Have you been memorizing field names or relying on F4 prompting?

When creating file joins using interactive SQL (STRSQL), it's sometimes difficult to remember the field names that you want to join. I typically don't memorize field names and totally rely on the F4 prompting to get the names from the "SELECT fields" line.

The usage of SQL stored procedures by IBM i applications and programs continues to rise. For quite awhile, applications have had the ability to leverage the performance benefits offered by IBM i service program objects.

 

With a recent V6R1 PTF, SQL stored procedures can now benefit from the improved performance offered by IBM i service program objects. When an SQL stored procedure is created, DB2 for i generates and creates an ILE C program object to implement the business logic specified by the programmer. For example, when the following procedure is created, it will result in DB2 generating an ILE C program object (*PGM) named ADD_PGM in the QGPL library.  Whenever an application invokes the ADD_PGM, DB2 will transparently call the generated C program object.
