Informix Error -79864: Statement length exceeds the maximum.
Cause and resolution
Statement length exceeds the maximum.
Your application issued an SQL PREPARE, DECLARE, or EXECUTE IMMEDIATE statement that is longer than the database server can handle. The limit differs with different implementations but in most cases is up to 65,535 characters.
Review the program logic to ensure that an error has not caused your application to present a string that is longer than intended. If the text has the intended length, revise the application to present fewer statements at a time.
This error is the same as error -460 that the database server returns.
Oninit® Troubleshooting Guidance
Reasons / Common Causes
-79864 fires when an SQL PREPARE/DECLARE/EXECUTE IMMEDIATE statement exceeds what
the database server can handle — per the official guidance, the limit varies by
implementation but is often up to 65,535 characters. This is the JDBC-driver-reported
form of the same condition as database server error -460.
- A statement longer than the server's implementation-specific length limit, per the official guidance — the direct, only cause.
Solutions / Resolution
- Review the program logic to confirm the statement isn't accidentally longer than intended, per the official guidance.
- If the length is intended, split the work into multiple statements presented at a time, per the official guidance.
Examples
N/A
No specific triggering statement is documented beyond exceeding the length limit.
Diagnostic Checks
- Check the statement's actual length, and confirm it's within the implementation's limit (often 65,535 characters); split it into multiple statements if not.

- -460 — "Statement length exceeds maximum." The equivalent database server error this JDBC code mirrors, per the official guidance's own note that they're the same condition.
An SQL statement exceeded the server's implementation-specific length limit — split it into multiple statements if the length is genuinely needed.
