Short version for easy use   SELECT    FROM  TableName  t WHERE t  DateColumnName   gt   DATEADD month  -1  GETDATE      DATEADD and GETDATE are available in SQL Server starting with 2008 version  MSDN documentation  GETDATE and DATEADD

You should be using DATEADD is Sql server so if try this simple select you will see the affect  Select DATEADD Month  -1  getdate      Result  2013-04-20 14 08 07 177   in your case try this query  SELECT name FROM   SELECT name FROM  Hist answer WHERE id city  34324  AND datetime  gt   DATEADD month -1 GETDATE    UNION ALL SELECT name FROM  Hist internet WHERE id city  34324  AND datetime  gt   DATEADD month -1 GETDATE      x GROUP BY name ORDER BY name
