• Use SQL query statements to update or delete problematic records.
• Consider using data cleaning tools to fix data inconsistencies.

3. Optimize related queries

• Use indexes in queries to improve efficiency.
• Limit the number of columns in the query result set and only obtain necessary fields.
• Use LEFT JOIN or RIGHT JOIN queries instead of INNER JOIN to avoid filtering empty records in related tables.
