====== Find Duplicate Rows By Specific Columns ====== Consider a table, MyTable, with four columns: KeyCol, NameCol, IsActive, RowVersion. If you wanted to find all rows where NameCol and IsActive have the same values, you could do it as follows: SELECT * FROM (SELECT NameCol, IsActive, count(*) AS DupCount FROM MyTable GROUP BY NameCol,IsActive) AS ResultSet WHERE ResultSet.DupCount > 1
