First, see if there is any data in the table at all.SELECT TOP 10 adddttm, refundamount, moddttm, refundeddttm, refundstatusdttmFROM billing.refund
If there is, try changing the where clause to one of these:WHERE adddttm = CAST('08/22/2012' AS DATETIME)WHERE CAST(adddttm AS DATETIME) = CAST('08/22/2012' AS DATETIME)WHERE adddttm >= CAST('08/22/2012' AS DATETIME) AND addttm < CAST('08/23/2012' AS DATETIME)
If none of that seems to work, post the results of this query:SELECT DATA_TYPE FROM INFORMATION_SCHEMA.[COLUMNS] cWHERE c.TABLE_NAME = 'refund' AND c.TABLE_SCHEMA = 'billing'AND c.COLUMN_NAME = 'adddttm'
