存储过程不会返回任何后续查询的值

推荐答案

嗨Baskaran



试试这个

Hi Baskaran

Try with this

ALTER procedure sp_getstudentforsearchbyrollno(@rollno int)
as
begin

DECLARE @tab table (AdmissionNumber int, RollNumber int, StudentName nvarchar(500),Standered_name nvarchar(500),Section_name nvarchar(500))

INSERT @tab
select sar.AdmissionNumber,ra.RollNumber,sa.StudentName,cn.Standered_name,sn.Section_name from School.dbo.StudentRollNumberAllocation_details ra  join  School.dbo.StudentAdmission_details  sa on sa.AdmissionNumber=ra.AdmissionNumber  join School.dbo.Student_Acadamic_details  sar on sar.AdmissionNumber=ra.AdmissionNumber  join School.dbo.Standered_details cn on cn.Standered_id=ra.classid  join School.dbo.Section_details sn on sn.Section_id=sar.Section_id where ra.RollId=@rollno

SELECT * FROM @tab

end

另一种方法是从用户定义的函数返回一个表变量，我不是这个方法的忠实粉丝。但它适合您的要求。



问候，

Vijay

An alternative approach is to return a table variable from a user defined function , I am not a big fan of this method. But it is fit for your requirement.
