I think I found an issue with TOAD.
TOAD version: TOAD for IBM DB2 220.127.116.11.
The following SQL will fail:
Select * from TblTest
fetch first 1 row only;
–for fetch only;
The error message is the following:
Error:10/12/2015 9:21:20 AM 0:00:00.056: Lookup Error - DB2 Database Error: ERROR  [IBM][DB2] SQL0198N The statement string of the PREPARE or EXECUTE IMMEDIATE statement is blank or empty.
The reason is because I commented out a line after the ; sign. If I move the ; sign after the commented line the SQL will run fine.
Can we try to get this fixed in future release?
