Altering Stored Procedures in Java (SPJs)
Steps for Altering an SQL/MP Alias
1. Start an MXCI session. Enter a LOG command to initiate a log file for statements
and commands entered in this session. Keep the log for your records.
2. Determine the name of the SQL/MP alias you want to alter.
3. Use the DISPLAY USE OF command to identify which user modules are
associated with this object. See the similarity check criteria in the SQL/MX
Programming Manual for C and COBOL and the SQL/MX Programming Manual for
Java to determine if your changes are likely to cause similarly check to fail and
force automatic recompilation. If they will, you should SQL compile these modules
after making the changes to avoid expensive automatic recompilations at run time.
SQL applications that are running while you make these changes will still undergo
automatic recompilation.
For information about explicit and automatic recompilation, see the SQL/MX
Programming Manual for C and COBOL and the SQL/MX Programming Manual for
Java. For information about using DISPLAY USE OF, see Checking Module
Dependencies With DISPLAY USE OF on page 11-20 and the SQL/MX Reference
Manual.
4. Enter the ALTER SQLMP ALIAS statement.
5. Revise the application source code as needed to reflect your changes to the
database. Process and compile the updated source file. For more information, see
the SQL/MX Programming Manual for C and COBOL and the SQL/MX
Programming Manual for Java.
For more information and examples of altering SQL/MP aliases, see the SQL/MX
Reference Manual.
Altering Stored Procedures in Java (SPJs)
For information and examples of altering SPJs, see the SQL/MX Guide to Stored
Procedures in Java.
Altering System Defaults
For information and examples of altering system defaults, see Section 6, Reviewing
and Setting System Defaults.
Altering Tables
You can use various statements and utilities to alter SQL/MX tables in many ways. For
detailed information about these statements and utilities, see the SQL/MX Reference
Manual.
