Mysql Duplicate rows - same table - not primary col

 / Published in: MySQL
 

Look for duplicate rows, in the same table, by a different column (not primary or unique).

Expand | Embed | Plain Text 
  1. SELECT p1.id,p1.cod , p2.id,p2.cod #here we find the duplicate data from cod column, but i need the ID to show ...
  2. FROM `st_produse` p1 #the table, first time 
  3. LEFT JOIN st_produse p2 ON p1.cod = p2.cod #the table second time
  4. WHERE p1.id <> p2.id #here put the key or a unique column
  5. GROUP BY p1.cod #the column in case, first time
