Tips
- Use the Query Design window in SQL Wizard when you want to add new DML commands to your program but are not sure of the correct syntax. Create your query and run it until you are happy that results are correct. Then open the SQL window and copy the SQL statements into your program, between the EXEC SQL and the end-of-procedure statements.
- If you are writing a program that needs to create a table and you have a test table with the correct structure, use SQL Wizard's Export capabilities to generate the DDL commands for your program.
- If you create date columns in a test table using the WITH DEFAULT constraint, you can use the Date Warp feature of the IDE to change the system date on a row-by-row basis, without having to restart the XDB Server.
- SQL Option automatically commits changes to a database when the end of a program procedure is reached with no errors. If an error occurs or if you stop debugging prior to reaching the end of a procedure, a rollback is performed instead. You do not need to use the LOGOFF directive when running a COBOL application.
