I am getting an error incorrect syntex near the keyword where. If I take out the where the query works..any suggestions.

SELECT T0.CardCode, T0.CardName, T0.NumAtCard, T0.DocNum, T0.DocDate,

T0.DocTotal, T0.PaidToDate, (T0.DocTotal- T0.PaidToDate) as 'Balance'

FROM dbo.OINV T0 WHERE T0.DocStatus ='O'

WHERE T0.CardName LIKE '%[%0\]%'
