适合经常改变where子句的代码



SQL：create proc procBP_Cost_UpdateCost
as
SELECT  a.ModelGroupID, a.ProductCost
FROM   T_ProductCost AS a INNER JOIN

        T_BPCost ON a.ModelGroupID = T_BPCost.ModelGroupID
WHERE     EXISTS (
SELECT   MAX(CONVERT(int, PCYear + PCMonth)) AS Version, ModelGroupID
FROM     T_ProductCost
GROUP BY ModelGroupID, ProductCostID
HAVING  (MAX(CONVERT(int, PCYear + PCMonth)) = CONVERT(int, a.PCYear + a.PCMonth)) AND (a.CostCommit = 'Y'))

后台：
DataSet ds = db.GetDataSetbyProc("procBP_Cost_UpdateCost");
 
  public DataSet GetDataSetbyProc(string procName)

        {
