Not every SQLCODE other than 0 or 100 is an error - only those < 0 are hard errors. I was told to do something like this - I prefer a first Fetch, then the Dow loop with a Fetch before the EndDo - I know, this is a religious choice, so I will not discuss it!!
dow sqlcode >= 0 and sqlcode <> 100;
Positive SQLCODE are often about something that makes the statement less efficient - 12 (unqualified correlation) or 30 (# of host variables different from # of result values) might not be a problem, they are just an indication of sloppy coding practice.

After all Fetch or Select, you must control the result of these operations,
using SQLCODE verification, through an IF, the value returned by SQLCODE =
0000, operation was performed correctly, in this case FETCH was able to
read a record or Select found what
I was looking for, SQLCODE = 0100, It means that the FETCH or SELECT
operation did not find anything, any other value is ERROR
