hi,

In a COBOL/DB2 environment, Does the host variables have data if the Sql query returns the error code of -811.

Thanks,
Anil

depends on your version of db2.
vsn 6 and below will populate.
vsn 7 and above will not guarantee population of host variables.

vsn7 and above, you need to use the FETCH FIRST ROW ONLY
to guarantee population of host variables.
V7 does not allow you to code ORDER BY in a singleton select.
