Informix Error -2018: A grammatical error has been found on line line, character column. The construct is not understandable in its context.
Cause and resolution
A grammatical error has been found on line line, character column. The construct is not understandable in its context.
This message points to the exact spot in a source file where the compiler could no longer understand the input. The actual mistake might be earlier in the file, perhaps several lines earlier, but it is not later. Other, more specific error messages should also appear.
Oninit® Troubleshooting Guidance
Reasons / Common Causes
-2018 fires when the compiler can't parse a construct at a specific line/character position — per the official guidance, the reported position is where parsing actually failed, but the real mistake may be earlier in the file; this message typically accompanies other, more specific error messages.
- A genuine syntax error at (or before) the reported position, per the official guidance — the direct, only cause, though the actual mistake may be upstream of where parsing broke down.
Solutions / Resolution
- Check for additional, more specific error messages accompanying this one, per the official guidance, since -2018 alone only reports where parsing failed, not necessarily why.
- Review the source starting from the reported position, and work backward if nothing looks wrong there, since the actual mistake may be earlier in the file.
Examples
N/A
No specific triggering statement is documented — this is a generic parse-failure position report; check accompanying messages for the specific cause.
Diagnostic Checks
- Check the reported line/character position, and the accompanying more-specific error messages, for the actual syntax mistake.
