Introduction to the NonStop SQL/MX Report Writer Database Organization For information on the SQL/MP language, see the SQL/MP Reference Manual . Database Organization In an SQL/MX database, data is organized and maintained in tables. A table consists of vertical columns and horizontal rows: A row contains pieces of related data, such as an employee's identification number, name, and address. A column contains data of the same type, such as all employee ID numbers. Columns have names; rows do not.
Introduction to the NonStop SQL/MX Report Writer SQL Database Reports SQL Database Reports MXCI generates a default report definition for each SELECT command you enter during your Report Writer session. You can override the default report by using layout options, style options, and report formatting commands. Layout and style options are global and not related to a specific SELECT command.
Introduction to the NonStop SQL/MX Report Writer Report Development Steps Report Development Steps The steps for using the MXCI report writer to develop a report are described in detail in the remainder of this guide. This summary provides an overview: 1. Setting report writer mode Before developing a report, you must set report writer mode . Note. All the examples in this guide assume that you have set report writer mode before executing any report writer commands. 2.
Introduction to the NonStop SQL/MX Report Writer Report Layout and Style To change the appearance of a report, use the layout options to determine: Margins The number of lines per page Line spacing Whether default headings are to print above columns of data 4. Customizing the style Use the style options to customize: 5.
Introduction to the NonStop SQL/MX Report Writer Default Report Format Default Report Format You can display or print a report without specifying any report formatting commands, layout options, or style options. The report is produced in the default format and is called the default report. The tables referred to are in the same catalog and schema, so your default catalog and schema should have been set at the beginning of this session.
Introduction to the NonStop SQL/MX Report Writer Default Layout and Style Options The WHERE clause also specifies that rows of the PARTS table are joined with rows of the ODETAIL table when the rows have the same part number. The components of the default report are: Detail lines Each detail line contains all elements of the select list in the order you specify in the SELECT command. (In Figure 1-2, the columns of data correspond to the data items as they were listed in the SELECT command.
Introduction to the NonStop SQL/MX Report Writer Customized Reports For a summary of layout and style options, which includes the default setting of each option, see Report Writer Components on page 1-12. For detailed information about layout and style options, see the SQL/MX Reference Manual. Customized Reports By entering report formatting commands, you can define these additional report elements: Page title: A title appears at the top of each page.
Introduction to the NonStop SQL/MX Report Writer The report contains: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.

Using MXCI and the Report Writer Starting and Ending an MXCI Session Starting and Ending an MXCI Session To start an MXCI session, at the OSS shell prompt, enter: /home/sql:mxci Hewlett-Packard NonStop(TM) SQL/MX Conversational Interface 2.0 (c) Copyright 2003 Hewlett-Packard Development Company, LP. >> When waiting for a command, MXCI displays the standard MXCI prompt (>>).
Using MXCI and the Report Writer The Elements of Your Session Environment The catalog and schema you have set are in effect until the end of your session or until you execute another SET CATALOG or SET SCHEMA command. Note. All examples in this guide assume that you have already set the correct names for the catalog and schema, as appropriate, at the beginning of your session. The Elements of Your Session Environment CURRENT DIRECTORY Path name of the current server directory.
Using MXCI and the Report Writer Invoking Report Writer Mode Use the ENV command to display the current default settings, as shown: >> env; ---------------------------------Current Environment ---------------------------------CURRENT DIRECTORY /usr/yourdir/bin HOME DIRECTORY /usr/yourdir LIST_COUNT 4294967295 LOG FILE MESSAGEFILE /usr/yourdir/bin/mxcierrors.cat TERMINAL CHARSET ISO88591 MESSAGEFILE LANG US English MESSAGEFILE VRSN {2003-09-19 09:43 NSK:FIGARO/SUPER.
Using MXCI and the Report Writer Setting and Displaying Options Setting and Displaying Options There are three basic commands for working with options: SET, RESET, and SHOW. There are two types of options you can use to customize your reports: Layout options, such as line spacing and margin settings, control the appearance of a report on the screen or printed page. Style options, such as the decimal character and underline character, control the appearance of items in a report.
Using MXCI and the Report Writer Listing Rows of a Report You can use the RESET, RESET LAYOUT, and RESET STYLE commands to reset specific options or all options to their default values. For example, to reset the line spacing to 1 (single spacing) and reset all style options to their default values, enter: >> RESET LAYOUT LINE_SPACING; >> RESET STYLE * ; You can enter SET, RESET, and SHOW commands at the standard MXCI prompt (>>) or the select-in-progress prompt (S>).
Using MXCI and the Report Writer Canceling a SELECT Command Figure 2-2.
Using MXCI and the Report Writer Defining a Window for Report Output Defining a Window for Report Output If your report is wider than the maximum width of the device on which you are displaying or printing it, the device determines at what point an output item will wrap to the next line. Use the SET LAYOUT WINDOW command to specify which vertical portion of the report you want to see. For example, suppose that a report is designed for a printer that prints 120 single-byte characters per line.
Using MXCI and the Report Writer Defining a Window for Report Output At the select-in-progress prompt only, you can define a window by the column name or column number of the left most select item you want to display. For example, to display the fourth column of the select list, enter: S> SET LAYOUT WINDOW COL 4; Figure 2-4 illustrates the relation of the left edge of a window to the output line of a report. At each numbered step, the headings and first row are displayed.
Using MXCI and the Report Writer Entering Report Formatting Commands Figure 2-4. Relation of Window to Output Line 1 Default left edge of window is TAB 1 (First position of output line is at left edge of window.) (Screen Position 64) (Left margin of 5 print positions is part of output line.) DEPTNUM DEPTNAME 1000 MANAGER 23 FINANCE LOCATION EMPNUM CHICAGO 23 2 SET LAYOUT WINDOW TAB 15 (15th position of output line moves to left edge of window.
Using MXCI and the Report Writer Entering Report Formatting Commands Figure 2-5.

Using MXCI and the Report Writer Entering Report Formatting Commands You can enter only one version of each of these commands at one time: BREAK ON DETAIL PAGE FOOTING PAGE TITLE REPORT FOOTING REPORT TITLE TOTAL If you enter a second version of any of these commands, that version replaces the previous one. A report formatting command is canceled if you do any of the following: Cancel the current SELECT command. Enter LIST ALL. Reset the command using RESET REPORT.
Using MXCI and the Report Writer Specifying Log Files However, if you enter the SUBTOTAL COL 2 command, only column 2 will be subtotaled: S> BREAK ON DEPTNUM, JOBCODE; S> SUBTOTAL COL 1; . . S> SUBTOTAL COL 2; Suppose you enter these commands: S> BREAK ON DEPTNUM; S> BREAK TITLE DEPTNUM ("Department Number:", DEPTNUM); If you decide you want to change the break title, reenter the command: S> BREAK TITLE DEPTNUM ("Dept. No. ", DEPTNUM); The second BREAK TITLE command replaces the first.
Using MXCI and the Report Writer Repeating Stored Commands Use the PREPARE and EXECUTE commands. (For an example, see Preparing a SELECT Command on page 3-25.) Use the OBEY command. To execute a set of commands repeatedly, use a text editor to put the commands in a command file. For more information on examples of creating command files, see Defining Reports in Command Files on page 2-15.
Using MXCI and the Report Writer Defining Reports in Command Files Figure 2-6. Repeating Stored Commands Example 1 >> FC SELECT >> SELECT PARTNUM, QTY_AVAILABLE ..

Selecting Data for a Report Setting Criteria for Selecting Data The select list must specify each column of data used in the report. For example, a column value you print in a title or footing does not have to appear in the detail line, but it must be retrieved in the select list. You select specific columns by specifying column names. The select list for the supplier parts summary consists of the column names in boldface type: >> SELECT S.SUPPNUM, +> SUPPNAME, +> CITY, +> STATE, +> P.
Selecting Data for a Report Setting Criteria for Selecting Data To select only rows describing parts with at least 50 units available, enter: >> SELECT * +> FROM PARTS +> WHERE QTY_AVAILABLE >= 50; In the next example, the WHERE clause specifies conditions for selecting rows and specifies the method for joining three tables. Only information about local suppliers is selected; that is, suppliers in areas with postal codes between 95400 and 95500. >> +> +> +> +> +> +> +> SELECT S.SUPPNUM, SUPPNAME, P.
Selecting Data for a Report Setting Criteria for Selecting Data Table 3-1. Search Condition Predicates Predicate Purpose Comparison Compares values of two expressions, two sets of expressions, or the value of an expression and a single value resulting from a subquery. For example: PARTNUM = 244 (Part number must equal 244.) Quantified Compares the value of an expression to all or any of the values of a single column result from a subquery.
Selecting Data for a Report Setting Criteria for Selecting Data These examples illustrate the effect of each predicate when included in the SELECT command: >> +> +> +> +> +> +> SELECT P.PARTNUM, QTY_AVAILABLE, PARTCOST, PRICE FROM SAMDBCAT.SALES.PARTS P, SAMDBCAT.INVENT.PARTSUPP PS, SAMDBCAT.INVENT.SUPPLIER S WHERE P.PARTNUM = PS.PARTNUM AND PS.SUPPNUM = S.SUPPNUM ( Substitute predicate example from following text.
Selecting Data for a Report Comparing a Set of Columns to a Set of Values In the next example, the subquery (shown in boldface type) selects from the PARTLOC table part numbers for parts with greater than 500 units on hand in a single location. The main query selects the part description and price for these parts from the PARTS table. >> +> +> +> +> S> SELECT PARTNUM, PARTDESC, PRICE FROM SAMDBCAT.SALES.PARTS WHERE PARTNUM IN (SELECT PARTNUM FROM SAMDBCAT.INVENT.
Selecting Data for a Report Comparing Character Values This query selects employee numbers and job codes for all employees whose names are between CLARK, LARRY and FOLEY, MARK: >> +> +> +> SELECT EMPNUM, JOBCODE FROM EMPLOYEE WHERE LAST_NAME, FIRST_NAME BETWEEN 'CLARK', 'LARRY' AND 'FOLEY', 'MARK'; The names CLARK, JUNE and FOLEY, MAVA would not be selected.
Selecting Data for a Report Comparing Character Values Use the LIKE predicate to search for similar values by specifying only a few characters and using these wild-card characters: % (percent sign) Indicates zero or more characters of any type are acceptable. _ (underscore) Indicates any single character is acceptable. Character data can be stored in columns of data type CHAR, PIC X, VARCHAR, NATIONAL CHAR, and NCHAR.
Selecting Data for a Report Comparing Character Values Table 3-2.
Selecting Data for a Report Specifying More Than One Condition Specifying More Than One Condition You can use the Boolean operators NOT, AND, and OR to select data that satisfies more than one condition: >> +> +> +> +> SELECT PARTNUM, PARTDESC FROM PARTS WHERE QTY_AVAILABLE < 2500 AND PARTNUM BETWEEN 2000 AND 3000 OR PARTNUM > 6000 ; The order of evaluation is: 1. Expressions within parentheses 2. NOT 3. AND 4.
Selecting Data for a Report Sorting the Data Sorting the Data The ORDER BY clause of the SELECT command determines the order in which rows appear in the report. For example, the rows selected by the query in Figure 3-3 are displayed in descending order by quantity available. Figure 3-3. Rows Sorted by One Column >> SELECT * FROM SALES .
Selecting Data for a Report Grouping Data for Calculations Figure 3-4. Rows Sorted by Two Columns >> SELECT * FROM SALES.ODETAIL +> WHERE QTY_ORDERED > 30 +> ORDER BY PARTNUM, QTY_ORDERED DESC; S> LIST ALL; ORDERNUM PARTNUM UNIT_PRICE QTY_ORDERED 1000.00 1000.00 1900.00 1900.00 240.00 500.00 700.00 425.00 415.00 60 36 65 40 48 70 36 40 36 600480 2001 2001 400410 2003 700410 2003 600480 6301 400410 6400 400410 6401 800660 7301 600480 7301 400410 --- 15 row(s) selected.

Selecting Data for a Report Grouping Data for Calculations The GROUP BY clause determines the rows to which the function is applied. Each group of rows with the same part number is processed to determine a sum.
Selecting Data for a Report Counting Rows the select list and to the GROUP BY clause. The same rows will be grouped. You must qualify the PARTNUM column or the reference will be ambiguous. >> SELECT O.PARTNUM, PARTDESC, SUM (QTY_ORDERED) +> FROM ODETAIL O, PARTS P +> WHERE O.PARTNUM = P.PARTNUM +> GROUP BY O.
Selecting Data for a Report Determining Minimum and Maximum Values CUSTNUM CUSTNAME (EXPR) ------- ------------------ -------------------21 CENTRAL UNIVERSITY 1 123 BROWN MEDICAL CO 2 143 STEVENS SUPPLY 1 You can also select and display only the grouped rows that have more than two orders by moving the COUNT function to the WHERE clause as shown: >> MODE REPORT; >> SELECT C.CUSTNUM, CUSTNAME +> FROM CUSTOMER C, ORDERS O +> WHERE C.CUSTNUM = O.CUSTNUM +> AND COUNT (DISTINCT ORDERNUM) >= 2 +> GROUP BY C.
Selecting Data for a Report Determining Which Columns to Group Determining Which Columns to Group By specifying different sets of columns in the GROUP BY clause, you change the results of functions you apply to the group. For example: This example counts employees in departments numbered less than 2000. Department 1000 has five employees.
Selecting Data for a Report Selecting Distinct Rows The group to which the function is applied is determined by all the grouping columns you specify. The last column you specify determines how precisely the groups are divided. Note. You do not have to specify an ORDER BY clause unless you want the groups arranged in a particular order or you want to specify break groups in the report. For more information, see Organizing Rows Into Break Groups on page 4-15.
Selecting Data for a Report Using Expressions to Calculate Report Values a part, more than one row of the PARTSUPP might describe the same part number and supplier.

Selecting Data for a Report Preparing a SELECT Command Named parameters can be useful in a report definition that you specify in an EDIT file and execute by using the OBEY command. To set the value, an operator enters a command before executing the command file. For example: >> SET PARAM ?CUSTNO 324 ; You can specify the value for a parameter as a numeric or string literal, or you can use the CURRENT_TIMESTAMP or COMPUTE_TIMESTAMP functions to calculate the value.
Selecting Data for a Report Using Views This SELPREP file contains this PREPARE command: PREPARE SELCUSTINFO FROM ' SELECT * FROM CUSTOMER C, ' ' ORDERS R, ' ' ODETAIL OD, ' ' PARTS P ' ' WHERE C.CUSTNUM = R.CUSTNUM ' AND R.ORDERNUM = OD.ORDERNUM ' AND OD.PARTNUM = P.PARTNUM ' AND C.CUSTNUM = ? ' ' AND SALESREP = ?'; ' ' ' The SELECT command contains two unnamed parameters to be given values through an EXECUTE command.
Selecting Data for a Report Using Views information. The view columns are specified in parentheses following the view name. The rest of the command specifies the selection of columns and rows for the view. >> CREATE VIEW CUSTORD +> ( CUSTNUM, CUSTNAME, +> STREET, CITY, STATE, POSTCODE, +> CREDIT, +> ORDERNUM, ORDER_DATE, DELIV_DATE, +> SALESREP, +> PARTNUM, UNIT_PRICE, QTY_ORDERED ) +> AS SELECT +> C.CUSTNUM, CUSTNAME, +> STREET, CITY, STATE, POSTCODE, +> CREDIT, +> O.

Selecting Data for a Report Using Subqueries A correlated subquery is evaluated for each row selected by the main query. A subquery that does not contain a correlated reference is evaluated once. The result is used for evaluating the WHERE clause against each row selected by the main query.
Selecting Data for a Report Using Subqueries The subquery is evaluated for each row selected by the main query. The FROM clause of the main query defines the correlation name XP for the PARTSUPP table. The subquery defines the correlation name P for the PARTSUPP table. The WHERE clause defines the correlation. The subquery averages rows from the PARTSUPP table with a PARTNUM value equal to the PARTNUM value of the current row from the outer query.

Customizing a Report Defining the Layout Defining the Layout You control the layout of a report by specifying margins, pagination, and spacing. Setting Margins The current settings of the layout options LEFT_MARGIN and RIGHT_MARGIN determine the margins of a report. If you want a margin to precede the leftmost printed item in your report, set the left margin to the number of blanks needed.
Customizing a Report Setting Margins If you are specifying a detail line, insert a SKIP clause before a print item to force the item to be printed on the next line. Figure 4-1 and Figure 4-2 illustrate the default margin settings for displayed and printed output. Figure 4-1.

Customizing a Report Setting Margins Figure 4-2. Default Margin Settings in a Printer Report Printed Report Left Margin 0 Print Position 1 Right Margin Output Device Width VST0402.vsd The default top and bottom margins are one line each. You can increase the apparent size of these margins with a PAGE TITLE or PAGE FOOTING command. If you have no title, specify PAGE TITLE '' for a top margin of 3 lines or specify PAGE TITLE SKIP desired-margin-size - 3 for more than 3 lines.
Customizing a Report Setting Margins If you specify text in the title line, specify PAGE TITLE SKIP desired-marginsize - 1, ' text'. For example, to produce a desired margin size of 4 lines (SKIP 4 - 1 = SKIP 3), enter: S> PAGE TITLE SKIP 3, 'Summary of Employees'; ( 4 blank lines appear here. ) Summary of Employees CUSTNUM CUSTNAME ------- -------In this case, the four blank lines are created as follows: The first blank line is the default top margin.
Customizing a Report Paginating Paginating The report writer features that control where page breaks occur in a report are: PAGE_LENGTH Specifies the number of lines from the top to the bottom of a page. For example, to set a page length of 55 lines, enter: >> SET LAYOUT PAGE_LENGTH 55; Default page length for a printed report = 60 lines. Default page length on a terminal is ALL. (The entire report is a single page unless you specify the PAGE clause.
Customizing a Report Paginating You can specify the maximum number of pages to be printed in a report by setting the PAGE_COUNT layout option. For example, to set the limit to 100 pages, enter: >> SET LAYOUT PAGE_COUNT 100; The default PAGE_COUNT value is ALL. The entire report is printed or displayed. To number the pages in a report, use the PAGE_NUMBER function to retrieve the number of the current page. The first page of the report is numbered 1.

Figure 4-6 shows the resulting report. Figure 4-6.
Customizing a Report Labeling Information You can specify a break column that is not in the detail line. The break occurs, but the item is not printed. For example, you might want to print the break column value in the break title but not in the detail line. If the break column is an item in the detail line: SUPPRESS ensures that the column value appears only in the first row of the group. If a page break occurs in the middle of the group, the value appears again in the first row of the new page.
Customizing a Report Headings for Column Identifier Print Items 2. HEADING or NOHEAD clauses of the DETAIL command control headings for print items. You can specify a heading with the HEADING option for a print item in the detail list. You can also specify NOHEAD to suppress a heading for a print item. 3.

Customizing a Report Break Titles You can delete the break title associated with each specified break column by using the RESET REPORT BREAK TITLE ( column-list) command. To include an unnamed item from the detail line in a break title, you must define a detail alias name for the item. In this example, a report generates break titles for two break groups—one for each customer and one for each order. The CUSTNUM value in the first title is taken from the first row of each customer break group.

Customizing a Report Display Format Specifications The essential part of a display format is the display-descriptor. A display descriptor controls the width of a field and, for numeric values, the scale of the value. The display descriptors for character values are: A[ w] specifies alphanumeric display of width w. For example, A20 displays characters in a field that is 20 single-byte print positions wide. Values are left justified in this format. Note.
Customizing a Report Numeric Values Numeric Values Use the I and F display descriptors for numeric values. In this example, QTY_RECEIVED appears in the detail line. The data type defined for QTY_RECEIVED is NUMERIC (7); the value is always an integer. By default, the display format is I11. The DETAIL command specifies a narrower field.
Customizing a Report Monetary Values You cannot specify a scale-sign descriptor for an I display descriptor. >> SELECT P.PARTNUM, QTY_AVAILABLE, PARTCOST +> FROM SAMDBCAT.SALES.PARTS P, +> SAMDBCAT.INVENT.PARTSUPP PS, +> WHERE P.PARTNUM = PS.PARTNUM +> ORDER BY P.PARTNUM; S> DETAIL PARTNUM HEADING 'Part No.', +> PARTCOST AS F10.2 HEADING 'Part Cost/(dollars)', +> PARTCOST * QTY_AVAILABLE AS '-3P F10.2' +> HEADING 'Total Cost/(thousands/of dollars)', +> PARTCOST * QTY_AVAILABLE AS F15.

The form of decoration is: condition location char-string The entire display format must be enclosed in quotation marks.
Customizing a Report Suppressing Leading or Trailing Zeros In the first decoration, condition M specifies that this decoration applies if the value is negative. location A1 specifies print position 1 for printing charstring CR. In the second decoration, condition MP specifies that this decoration applies if the value is negative or positive. location and char-string are the same as those shown in Figure 4-16.
Customizing a Report Concatenating Text Use the uppercase letter Z to suppress leading and trailing zeros in a mask: Mask Value Result M 2.453 2.45 9023.00 9023.00 5432 5,432 300 0,300 0 0,000 M 300 300 M<$ZZZ9.99> 5432 $5432.00 300.153 $ 300.15 0 $ 0.00 M<9,999> You can use the BZ modifier to suppress all zeros when the value is zero; for example, AS ’[BZ] M’.
Customizing a Report Truncated Values To specify the width of the field, include an AS clause in the print item: CONCAT (FIRST_NAME STRIP, SPACE 1, LAST_NAME) AS A25 Truncated Values The VARCHAR_WIDTH style option specifies the maximum number of characters that can appear in a print item with a value of a variable-length character data type. The excess characters are truncated. The default is 80 single-byte characters. You can set a value up to 32767 single-byte (or 16383 double-byte) characters.
Customizing a Report Filler Characters A value in an A display descriptor field does not fill the field. For example, ’[FL''*''] A12’ produces FINANCE*****. Leading zeros are to be replaced. For example, ’[FL''*'']I6’ produces ***355. Embedded text in a mask descriptor is not printed because the digits that surround the text are not printed. For example, ’[FL''*'']M<$ZZZZ9.99>’ produces $**355.67.
Customizing a Report Formatting Dates and Times Formatting Dates and Times To format a date and time in your report, you must consider the data type of the date and time value to be formatted. The data type is determined by the way the value is generated or stored. Date and Time Values A report can contain dates and times selected from columns of the DATETIME, DATE, TIME, or TIMESTAMP data types. You can also use date-time literals or expressions to generate dates and times for a report.
Customizing a Report Julian Timestamp Formats You might also store a date as a numeric value but not as a timestamp. See Formats for Dates Stored as Binary Values on page 4-46. Julian Timestamp Formats By using the AS DATE/TIME clause, you can specify the date format and time format of a Julian timestamp.
Customizing a Report SQL/MX Date and Time Formats Table 4-2 summarizes the characters you use to specify date and time formats in an AS DATE/TIME clause, a DATE_FORMAT style option, or a TIME_FORMAT style option. Table 4-2.
Customizing a Report Converting Timestamps If you are formatting only a part of the date-time value, the applicable parts of the format are used. For example, if you specify YEAR TO DAY in the DATEFORMAT function, the EUROPEAN format will be dd.mm.yyyy. These print items produce identical formats: CURRENT DATEFORMAT (CURRENT, DEFAULT) A current date and time generated by either of these functions would appear as: 2000-04-15:18:22:05.
Customizing a Report Formats for Dates Stored as Binary Values Note that you do not need to include YEAR TO DAY with CURRENT because the AS DATE clause selects only the month, day, and year from the timestamp.

Customizing a Report Defining a Subtotal Label The OVER clause indicates when a subtotal is to be calculated. If you omit the OVER clause, the subtotals appear whenever any data value in any currently defined break column changes. Only one SUBTOTAL command without an OVER clause is in effect at one time. To delete all subtotal commands, enter: S> RESET REPORT SUBTOTAL; RESET REPORT BREAK also resets subtotals by deleting the specified break columns.
