Prepare and run a program with SQL statements

This topic describes some of the tasks for preparing and running an application program.

• Basic processes of the SQL precompiler
  You must precompile and compile an application program containing embedded SQL statements before you can run it.
• Non-ILE SQL precompiler commands
  DB2^® UDB Query Manager and SQL Development Kit includes non-ILE precompiler commands for the following host languages: CRTSQLCBL (for COBOL for iSeries™), CRTSQLPLI (for iSeries™ PL/I), and CRTSQLRPG (for RPG III, which is part of RPG/400^®).
• ILE SQL precompiler commands
  In the DB2^® UDB Query Manager and SQL Development Kit, the following ILE precompiler commands exist: CRTSQLCI, CRTSQLCPPI, CRTSQLCBLI, and CRTSQLRPGI.
• Set compiler options using the precompiler commands
  The COMPILEOPT string is available on the precompiler command and on the SET OPTION statement to allow additional parameters to be used on the compiler command.
• Interpret compile errors in applications that use SQL
  Sometimes you will encounter compile errors. Use the following information to interpret these errors.
• Bind an application that uses SQL
  Before you can run your application program, a relationship between the program and any specified tables and views must be established. This process is called binding. The result of binding is an access plan.
• Display SQL precompiler options
  When the SQL application program is successfully compiled, the Display Module (DSPMOD), the Display Program (DSPPGM), or the Display Service Program (DSPSRVPGM) command can be used to determine some of the options that were specified on the SQL precompile.
• Run a program with embedded SQL
  Running a host language program with embedded SQL statements, after the precompile and compile have been successfully done, is the same as running any host program.
