How can I remove duplicates from a SQL table?
You can use the DELETE
statement along with a subquery to remove duplicates. Would you like an example?
Yes, please provide an example.
Sure! You can use a query like this: DELETE FROM your_table WHERE id NOT IN (SELECT MIN(id) FROM your_table GROUP BY column_name);
This keeps the first occurrence.
What if I want to keep the latest entry instead?
In that case, you can modify the subquery to use MAX
instead of MIN
. Would you like to see that query?
