    Removing Duplicated rows from table

    Let's use ROW_NUMBER() to purge tables from duplicated data. You need to identify which set of columns are the unique key and then apply PARTITION over them. Thanks to Stefan Krzywicki. http://www.sqlservercentral.com/articles/duplicate+data/102383/
    DELETE q
        FROM ( SELECT ROW_NUMBER() OVER ( PARTITION BY Field1, Field2 ORDER BY Field1, Field2) R
