your question is not clear, give table structure and what do you want?

I have created a table and entered some duplicate rows into that table. Now I want to find out duplicate rows and delete them..

3 solutions

SQL

DELETE FROM Table1 WHERE Col1 NOT IN (SELECT MIN(Col1) FROM Table1 GROUP BY DupCol1, DupCol2, DupCol3)
