Description

This warning is used to report that a specific statement uses a variable or literal with an invalid query and for that reason, it will not be executed.

Example Code

Input Code:

REPLACE PROCEDURE TEST.COLLECT_STATS
(
)
BEGIN
COLLECT STATS ON DBC.AccessRights COLUMN(COLNAME);
SET STATS_STATEMENT = 'COLLECT STATS ON ' || OUT_DB || '.' || OUT_TBL || ' COLUMN(' || C4.ColumnName || ');';
EXECUTE IMMEDIATE STATS_STATEMENT;
EXECUTE IMMEDIATE 'COLLECT STATS ON DBC.AccessRights COLUMN(COLNAME);';
SET STATS_STATEMENT_NOT_DYNAMIC = 'COLLECT STATS ON DBC.AccessRights COLUMN(COLNAME);';
EXECUTE IMMEDIATE STATS_STATEMENT_NOT_DYNAMIC;
END;
;

Output Code:

The warning message appears every time an Execute uses a statement (variable or literal) with an invalid query. In the example, those lines are 15, 18, and 22.
