How to remove duplicate records in MySQL with WHERE condition

My address book table has many duplicate addresses for each client. Note in the screenshot below that I have many duplicate zip codes for the same client with ID 12.

What would the MYSQL statement look like in this case?

Thank you!

You can make a INNER JOIN with the same table to find the duplicates. In your case it will be considered a duplicate if there is another record with the same parent_id , the same post_code and a entity_id minor:

DELETE b
FROM 'catalog_address' a
INNER JOIN 'catalog_address' b ON a.'parent_id' = b.'parent_id' AND a.'post_code' = b.'post_code' AND a.'entity_id' < b.'entity_id'
WHERE a.'parent_id' > 1 AND a.'post_code' > 1;

To query the records that will be removed in DELETE above, use SELECT below:

SELECT b.*
FROM 'catalog_address' a
INNER JOIN 'catalog_address' b ON a.'parent_id' = b.'parent_id' AND a.'post_code' = b.'post_code' AND a.'entity_id' < b.'entity_id'
WHERE a.'parent_id' > 1 AND a.'post_code' > 1;
