Informix Error -33063: Already within BEGIN DECLARE SECTION.

Cause and resolution

Already within BEGIN DECLARE SECTION.

This message is a warning only. An EXEC SQL BEGIN DECLARE SECTION statement is inside another BEGIN/END DECLARE block. This statement is ignored. However, the warning might indicate a mix-up in the structure of your program. Check that all the declaration sections are properly delimited.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-33063 is a preprocessor warning — per the official guidance, an EXEC SQL BEGIN DECLARE SECTION appeared inside another BEGIN/END DECLARE block; the nested statement is ignored.

A BEGIN DECLARE SECTION nested inside another declare section, per the official guidance — the direct, only cause.

Solutions / Resolution

Check that all declaration sections are properly delimited, per the official guidance, since this may indicate a structural mix-up even though the statement itself is just ignored.

Examples

N/A

No specific triggering statement is documented beyond a nested BEGIN DECLARE SECTION.

Diagnostic Checks

Check the program's declare-section structure for an unintended nested BEGIN DECLARE SECTION.
