Showing the Syntax of an SPJ
The output of the SHOWDDL command does not exactly match the original CREATE
PROCEDURE statement in these ways:
•
The SHOWDDL command does not omit the optional clauses, such as
LOCATION, CONTAINS SQL, NOT DETERMINISTIC, and ISOLATE.
•
The SHOWDDL command always generates a Java signature for the SPJ.
•
The SHOWDDL command displays DECIMAL or NUMERIC data types instead of
PIC S9, when PIC S9 is specified for an SQL parameter, because NonStop
SQL/MX stores PIC S9 as one of these data types.
•
The SHOWDDL command displays CHARACTER data types instead of PIC X,
when PIC X is specified for an SQL parameter, because NonStop SQL/MX stores
PIC X as a CHAR data type.
•
The SHOWDDL command displays the NCHAR data type as a CHAR type with
UCS2 (or ISO88591, KANJI, or KSC5601) as the CHARACTER SET modifier.
•
All ANSI names are fully qualified.
•
All physical location names are fully expanded.
The SHOWDDL command for an SPJ named ADJUSTSALARY returns this output:
For more information about ADJUSTSALARY and its underlying SPJ method,
adjustSalary(), see Appendix A, Sample SPJs.
