Understanding ORA-01735 Error
The ORA-01735 error is thrown when an invalid option is used in an ALTER TABLE statement. The error message typically looks like this:
ORA-01735: invalid ALTER TABLE option
This error occurs when Oracle cannot understand the option specified in the ALTER TABLE statement, meaning there's a syntax error in the statement. To fix this error, you must identify the invalid option and correct the syntax.
Common Causes of ORA-01735 Error
Here are some common causes of the ORA-01735 error:
- Using an incorrect or unsupported option in the ALTER TABLE statement
- Misspelling an option in the ALTER TABLE statement
- Missing, incorrect, or misplaced keyword(s) in the ALTER TABLE statement
Step-by-step Solution to Fix ORA-01735 Error
Follow these steps to identify and fix the ORA-01735 error:
Step 1: Identify the Invalid Option
First, carefully review the ALTER TABLE statement that's causing the error. Look for any misspelled or misplaced options, keywords, or other syntax errors. If you're unsure about the correct syntax, consult the Oracle documentation for the ALTER TABLE statement.
Step 2: Correct the Syntax
Once you've identified the invalid option, correct the syntax of the ALTER TABLE statement. Make sure to use the correct options, keywords, and syntax as per the Oracle documentation.
Step 3: Test the Updated Statement
After correcting the syntax, execute the updated ALTER TABLE statement to see if the error is resolved. If the ORA-01735 error persists, re-examine the statement for any additional errors or discrepancies.
Step 4: Consider Other Causes
If the ORA-01735 error still occurs after correcting the syntax, consider other possible causes, such as:
- Insufficient privileges to execute the ALTER TABLE statement
- Issues with the database schema or object itself
Investigate these potential causes and take appropriate action to resolve the error.
