这么的存储过程在SQL2000里面是不是没效果

这样的存储过程在SQL2000里面是不是没效果？

SQL code

CREATE PROCEDURE spCustomerList@sqlWhere varchar(300) AS   Declare @sql varchar(500)   set @sql = 'SELECT * FROM [Customer] '   if (@sqlWhere!='')    declare @TempID int     begin        select @TempID=count(1)  from [Customer] where@Sqlwhere       if @TempID=0  return 0     elsereturn 1          endGO

SQL code

CREATE PROCEDURE spCustomerList@sqlWhere varchar(300) , @rtn int OUTPUTASbegin   Declare @sql varchar(500)   if (@sqlWhere is not null and len(@sqlWhere) > 0)      begin        declare @TempID int       set @sql = 'select @a = count(1)  from [Customer] where ' + @Sqlwhere        exec sp_executesql @sql , N'@a int output' , @TempID output         if @TempID = 0          return 0       else          return 1     endendGO
