How do I find duplicate values in my MySQL database table?

To find duplicates in a MySQL database table, you can run a query like the following:

select column_name, count(*) as count from table_name group by column_name having count > 1;

Ex. select name, count(*) from users group by name having count > 1;

This will display all records in the table ‘users’ who have duplicate ‘name’ values.
