sql 存储过程取值

一般的存储过程取值，有select查询，output输出参数，return返回值,raiserror 值，其中return必有返回值，如不指定return值，将返回0

SET NOCOUNT ON；设定是否返回受影响的行

多语句，取受影响的行数结果不准确

1, select 查询表数据返回

CREATE PROCEDURE [dbo].[GetMaxIssue]
AS
BEGIN
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    SELECT max( issue) as maxissue  from b_issuelist
END

 

2，OUTPUT参数取值

CREATE PROCEDURE [dbo].[GetMaxIssue]
@Maxissue int output
AS
BEGIN
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    SELECT @Maxissue = max( issue)  from b_issuelist
END

 

3,返回值取值

CREATE PROCEDURE [dbo].[GetMaxIssue]
@Maxissue int output
AS
BEGIN
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    SELECT @Maxissue = max( issue)  from b_issuelist   --OUTPUT 参数
return @maxissue + 1   --返回值
END

 

还有 raiserror 暂无实例
