Using EXECUTE, SELECT, or WITH as Cursor Names

Do not use an EXECUTE, SELECT, or WITH keyword as the name of a cursor. If you try to use one of these keywords as the name of a cursor in a FOREACH statement, the cursor name is interpreted as a keyword in the FOREACH statement. No workaround exists.

The following example does not work:

DEFINE execute INT;
FOREACH execute FOR SELECT col1 -- error, looks like
                                -- FOREACH EXECUTE PROCEDURE
    INTO var1 FROM tab1;
