Informix Error -943: Found a non-terminated comment ("/*" with no matching "*/").

Reasons / Common Causes

-943 fires when DB-Access encounters an unterminated /* ... */ comment while running a .sql script — per the official guidance, DB-Access doesn't currently support comments without a closing terminator.

1. A /* comment with no matching */, per the official guidance — the direct, only cause.
2. A closing */ accidentally deleted or omitted during editing, especially in a long, multi-line comment block.

Solutions / Resolution

1. Add the missing */ terminator, per the official guidance — DB-Access requires every /* ... */ comment to be properly closed.
2. Review the script for every /* and confirm a matching */ follows, especially in scripts with several comment blocks, since one unterminated comment can silently absorb the rest of the file.

Examples

The disallowed unterminated comment

/* This comment is missing its closing terminator
SELECT * FROM orders;

Corrected

/* This comment now closes properly */
SELECT * FROM orders;

Diagnostic Checks

1. Scan the script for every /* and confirm each has a matching */.
