SQLCODEs and message descriptions

Y'all

A recent thread spoke of warning messages in the context of adding columns to a file. So I thought I'd post something about the relationship between SQLCODEs and message descriptions.

There are both positive and negative SQLCODEs, the latter are typically warnings or information, while the latter are errors.

The general connection between SQLCODEs and message descriptions is that the SQLCODE digits are the final digits in a message ID that generally starts with SQL.

So an SQLCODE of 100 (row not found) has a message description in QSQLMSG of SQL0100 of severity 0.

And SQLCODE of -206 (column not in table) has a message description in QSQLMSG of SQL0206 of severity 30.

There are some 5-digit negative SQLCODEs, and all 5 digits are at the end of the message ID. So SQLCODE of -30000 (DRDA protocol error) has message ID SQ30000, severity 30.

So with all that, one should STILL check SQLCODE in programs - AND one can easily see a more expansive explanation of the meaning by looking in the joblog.

I hope this is useful - Buck, maybe this can go in the WIKI.
