ALTER PROCEDURE selectedrfp

IF(@bdename='All') 
EXEC (@query + @withoutbde) 
ELSE IF(@bdename!='All') 
EXEC (@query + @withbde) 
END 

EXEC selectedrfp @from='2010/01/01',@to='2011/06/22',@bdename='chad',@status=4

ローカル変数@bdenameなどは、動的SQLの有効範囲にありません。

パラメータを正しく設定するには、sp_executesqlを使用する必要があります。それらを連結しないでください。
