Oracle Database Error:
ORA-00900
What does this error mean?
Oracle could not parse the SQL statement because it uses invalid syntax, an unsupported statement type, or a statement that requires privileges not granted to the current session.
Common causes
- 1SQL generated by an ORM or ETL tool uses non-Oracle syntax (e.g. MySQL-specific statements)
- 2A stored procedure call is missing the CALL or EXECUTE keyword
- 3Comment syntax or line endings are malformed
- 4Using SQL:1999 or T-SQL features not supported in Oracle
How to fix it
- 1Step 1: Print the exact SQL being sent to Oracle and test it in SQL*Plus or SQL Developer.
- 2Step 2: Check for non-Oracle syntax: LIMIT/OFFSET → `FETCH FIRST N ROWS ONLY`, ISNULL → `NVL`, backticks → double-quotes.
- 3Step 3: Wrap procedure calls in `BEGIN ... END;` or use `CALL procedure_name();`.
- 4Step 4: Ensure the JDBC or ODBC driver is configured for Oracle dialect.
- 5Step 5: Remove any trailing semicolons from single statements passed via JDBC.
