The EXCSQL Structured Query Language Execute Command, courtesy of the iSeries Network

Download Execute SQL NOW : EXCSQL

EXCSQL was developped by Dan Riehl in October 97. It allows one to execute an SQL statement up to 550 characters long, right from a high level language program, without having to bother with Query Manager (QM).

This command should probably be part of the OS/400 operating system. The first time I used it was because of necessity: CPYF, even with a FROMKEY specification, is very slow compared to SQL, and SQL is powerful enough to do a lot of what CPYF does and then some - and then a lot more!

Query Manager has the ability to accept parameters, which can be blended into a QMQRY. EXCSQL uses this feature in an unusual way. It actually takes the parameter and uses it as the whole command variable.
