Explanation
The IMPORT

clause is used to specify the format of the data in the file, such as the delimiter.
Use
- Importing Data: Use
IMPORT

Important Points
- File Format: Ensure that the format of the data in the file matches the specified format in the
MODIFIED BY
clause. - Column Mapping: Verify that the columns in the file are correctly mapped to the columns in the target table.
- Permissions: Ensure that you have the necessary permissions to read the file and insert data into the target table.
