Remove duplicate rows in MySQL

Question

I have a table with the following fields:

id (Unique)
url (Unique)
title
company
site_id

Now, I need to remove rows having same titl

Answer 1

In Order to duplicate records with unique columns, e.g. COL1,COL2, COL3 should not be replicated (suppose we have missed 3 column unique in table structure and multiple duplicate entries have been made into the table)

DROP TABLE TABLE_NAME_copy;
CREATE TABLE TABLE_NAME_copy LIKE TABLE_NAME;
INSERT INTO TABLE_NAME_copy
SELECT * FROM TABLE_NAME
GROUP BY COLUMN1, COLUMN2, COLUMN3; 
DROP TABLE TABLE_NAME;
ALTER TABLE TABLE_NAME_copy RENAME TO TABLE_NAME;

Hope will help dev.
