RE: Count records in SQL

GET DIAGNOSTICS ... will only return information AFTER an SQL Statement is
run.

ROW_COUNT: (Except from the SQL Reference)
Identifies the number of rows associated with the previous SQL statement
that was executed. If
the previous SQL statement is a DELETE, INSERT, REFRESH, or UPDATE
statement, ROW_COUNT
identifies the number of rows deleted, inserted, or updated by that
statement, excluding rows
affected by either triggers or referential integrity constraints. If the
previous SQL statement is a
MERGE statement, ROW_COUNT identifies the total number of rows deleted,
inserted, and updated
by that statement, excluding rows affected by either triggers or referential
integrity constraints. If the
previous SQL statement is a multiple-row-fetch, ROW_COUNT identifies the
number of rows fetched.
Otherwise, the value zero is returned.

May be DB2_NUMBER_ROWS would be the better option: (Except from the SQL
Reference)
If the previous SQL statement was an OPEN or a FETCH which caused the size
of the result table to
be known, returns the number of rows in the result table. For SENSITIVE
cursors, this value can be
thought of as an approximation since rows inserted and deleted will affect
the next retrieval of this
value. Otherwise, the value zero is returned.

What about ...

exec sql GET DIAGNOSTICS :Rows = ROW_COUNT;
