ORA-13124 is an Oracle database error that occurs when a database is unable to determine the column id for a specified column string.
This error can occur when running a query that uses views or referring to a column name that is not found in the database.
Official Explanation:
ORA-13124 is triggered when the database server is unable to find the column id for the specified column string. This means that either the column name was misspelled or the column does not exist in the database.
Common Scenario:
A common scenario when faced with ORA-13124 is when attempting to query a database view. View columns might not exist if the underlying objects that define the view have changed.
Normal Handling:
The steps to resolve this error include:
1. Check that the column name is written correctly
2. Verify that the column name exists in the underlying table
3. Review any changes to the underlying table or view that might have caused the column to no longer exist or to have been misspelled
4. Update the view definition if necessary to account for any changes
