SQL内部拼接执行SQL语句时，实现变量参数化

exec sp_ExecuteSql执行的SQL语句拼接起是比较麻烦，如果关联的表多拼接过程是很容易出错的，下面这方法非常的好用，而且简单直观

if exists(select * from sysobjects where name=" porc_SeekProttoryProject")

drop proc SeekProttoryProject

go

create proc SeekProttoryProject

@shareSgin int,
@lotteryTypeId int,
@projcetStar varchar(500),
@term varchar(50)

as

declare @ParmDefinition nvarchar(500);
declare @prc_GroupStr nvarchar(600);
set @prc_GroupStr= N'select * from Yuanbo_OpenAward where TypeCatalog =@TypeCatalog and Trem IN (@Trem);

SET @ParmDefinition = N'@TypeCatalog tinyint,@Trem nvarchar(500)';

exec sp_ExecuteSql @prc_GroupStr, @ParmDefinition,
@TypeCatalog = @lotteryTypeId,@Trem=@projcetStar
