Stored procedure query for selecting values - sql-server

Question

I have a Test table
CREATE TABLE [dbo].[Test](
[TestId] [int] IDENTITY(1,1) NOT NULL,
[TestName] [nvarchar](50) NOT NULL,
[UserId] [int] NOT NULL,
[isDelete] [bit] NOT NULL,
and Questions table as
CREATE TABLE [dbo].[Questions](
[Qid] [int] IDENTITY(1,1) NOT NULL,
[Tid] [int] NOT NULL,
[Qtype] [int] NOT NULL,
[Question] [nvarchar](max) NOT NULL,
[isDelete] [bit] NULL,
Questions table stores all the questions for each test with Tid as foreign key.
I want to write a stored procedure to fetch TestName, TestId and number of questions in each test in a single stored procedure. But I am unable to get this.

Answer 1

You can write the stored procedure as:
CREATE PROCEDURE [dbo].[procGetNumberofQuestionsForTest]
AS
BEGIN
SELECT T.[TestId], T.[TestName], COUNT(Q.[Qid]) AS NumberOfQuestions
FROM [dbo].[Test] T
JOIN [dbo].[Questions] Q ON Q.Tid = T.TestId
GROUP BY T.[TestId], T.[TestName]
END
If you want to get the result for specific Test, then pass the parameter as #TestId INT and add the WHERE clause as WHERE T.[TestId] = #TestId before the GROUP BY.

Try this (table create, insert, proc creation and execution included);
CREATE TABLE [dbo].[Test](
[TestId] [int] IDENTITY(1,1) NOT NULL,
[TestName] [nvarchar](50) NOT NULL,
[UserId] [int] NOT NULL,
[isDelete] [bit] NOT NULL)
go
CREATE TABLE [dbo].[Questions](
[Qid] [int] IDENTITY(1,1) NOT NULL,
[Tid] [int] NOT NULL,
[Qtype] [int] NOT NULL,
[Question] [nvarchar](max) NOT NULL,
[isDelete] [bit] NULL
)
go
insert into [dbo].[Test]
values('test #1',1,0)
go
insert into [dbo].[Questions]
values(1,1,'what is life',0)
go
create proc dbo.MyInfo
as
select
t.TestName,
t.TestId,
[No Questions]=COUNT(q.Qid)
from
[dbo].[Test] t
inner join
[dbo].[Questions] q on t.TestId=q.Qid
group by
t.TestName,
t.TestId
go
exec dbo.MyInfo
go
