say this procedure have to be called
select #className = Name
from dbo.ClassNames
where id=#classId
select #sectionName = SectionName
from dbo.ClassSections
where id=#sectionId
select #className as 'Class Name',#sectionName as 'Section Name'
the other procedure is:
declare #className nvarchar(50),
#sectionName nvarchar(50)
EXEC [dbo].[testAll]
#regNo=#regNo
so how to assing value to #className and #classSection by calling the above procedure???
create procedures using OUTPUT
https://technet.microsoft.com/en-us/library/ms187004(v=sql.105).aspx
create procedure spOne (#param1 int OUTPUT, #param2 varchar(20) OUTPUT)
as
select #param1= x from table
create procedure spTwo (#param1 int, #param2 varchar(20))
as
select x from table where y=#param1
Declare variables
declare #param1 int
declare #param2 varchar(20)
exec procedure using OUTPUT
exec spOne #param1 OUTPUT, #param2 OUTPUT
Now those variables holds values generated inside spOne
exec spTwo #param1, #param2
I think you missed something. You can't actually use the return of the proc like that or assign a variable in another procedure, they are out of context.
I would solve this in one of the 2 ways:
Define a View returning the 2 fields you need, that way you could filter the results by #regNo and return its results in another procedure, just like a normal table.
Use the return as a OUTPUT field in the procedure. That could be a table or simple 1 of the fields.
Hope it helps...

I have a stored procedure like
CREATE PROCEDURE GetSerial (#param1 int, #param2 int)
AS
BEGIN
-- do some insert/updates, so I can't use function
DECLARE #value AS int;
SET #value = 3;
return #value;
END
Now I declare a table variable
DECLARE #Serials AS TABLE
(
ID int,
Value int
)
Now I wanna fill this table like
INSERT INTO #Serials (ID, Value)
SELECT 1, GetSerial(1,2) -- *How can I call this?
So, can anyone help me how can i call the GetSerial stored procedure inside the SELECT statement to fill my table?
I recommend you avoid getting into this pattern/thinking, because stored procedures only return INTs, and those ints are really intended to describe how well the operation went, not a result/data from the operation. Example: 0 => failed, 1=> succeeded. Not GetAgeInYears() => 29
https://learn.microsoft.com/en-us/sql/relational-databases/stored-procedures/return-data-from-a-stored-procedure?view=sql-server-2017 has a lot of info and concrete examples but in your specific case you'd need to execute the procedure and capture the result code into a variable then insert that:
DECLARE #ret INT;
EXEC #ret = GetSerial(1,2);
INSERT INTO #Serials VALUES(1, #ret);
Really you'd be better off using an output parameter or resultset if you have many values to return. See the above link for more
I have a stored procedure named [usp_Movie_GetUserPaidList] that takes two arguments #MovieID INT, #UserName Nvarchar(250) and returns data something like this
Exec usp_Movie_GetUserPaidList #MovieID, #UserName
IsPaidUser | IsSubscribeUser
0 0
Now in my another stored procedure I have something like
DECLARE #tblTemp1 TABLE (
MovieID INT
,IsPaidUser BIT
,IsSubscribeUser BIT
)
Here I know #MovieID value
Now I need to do something like
INSERT INTO #tblTemp1
SELECT #MovieID (EXEC [usp_Movie_GetUserPaidList] #MovieID,#userName )
Which is obviously not correct.
Help me to do so...Thank you for your time.
You need to take output in another variable and then use it:
DECLARE #Movieid int
EXEC #Movieid = [usp_Movie_GetUserPaidList] #MovieID,#userName
Here assumptions are:
1. You have #MovieID and #userName with you.
2. Your stored proc usp_Movie_GetUserPaidList is returning proper value.
Why don't you return MovieID in the output of stored procedure usp_Movie_GetUserPaidList since you know it there also. Then you can use simple insert in another stored procedure like :
INSERT INTO #tblTemp1
EXEC [usp_Movie_GetUserPaidList] #MovieID,#userName
How can i execute a stored procedure in another stored procedure in SQL server?
How will I pass the parameters of the second procedure.?
If you only want to perform some specific operations by your second SP and do not require values back from the SP then simply do:
Exec secondSPName #anyparams
Else, if you need values returned by your second SP inside your first one, then create a temporary table variable with equal numbers of columns and with same definition of column return by second SP. Then you can get these values in first SP as:
Insert into #tep_table
Exec secondSPName #anyparams
Update:
To pass parameter to second sp, do this:
Declare #id ID_Column_datatype
Set #id=(Select id from table_1 Where yourconditions)
Exec secondSPName #id
Update 2:
Suppose your second sp returns Id and Name where type of id is int and name is of varchar(64) type.
now, if you want to select these values in first sp then create a temporary table variable and insert values into it:
Declare #tep_table table
(
Id int,
Name varchar(64)
)
Insert into #tep_table
Exec secondSP
Select * From #tep_table
This will return you the values returned by second SP.
Hope, this clear all your doubts.
Suppose you have one stored procedure like this
First stored procedure:
Create PROCEDURE LoginId
#UserName nvarchar(200),
#Password nvarchar(200)
AS
BEGIN
DECLARE #loginID int
SELECT #loginID = LoginId
FROM UserLogin
WHERE UserName = #UserName AND Password = #Password
return #loginID
END
Now you want to call this procedure from another stored procedure like as below
Second stored procedure
Create PROCEDURE Emprecord
#UserName nvarchar(200),
#Password nvarchar(200),
#Email nvarchar(200),
#IsAdmin bit,
#EmpName nvarchar(200),
#EmpLastName nvarchar(200),
#EmpAddress nvarchar(200),
#EmpContactNo nvarchar(150),
#EmpCompanyName nvarchar(200)
AS
BEGIN
INSERT INTO UserLogin VALUES(#UserName,#Password,#Email,#IsAdmin)
DECLARE #EmpLoginid int
**exec #EmpLoginid= LoginId #UserName,#Password**
INSERT INTO tblEmployee VALUES(#EmpName,#EmpLastName,#EmpAddress,#EmpContactNo,#EmpCompanyName,#EmpLoginid)
END
As you seen above, we can call one stored procedure from another
Yes, you can do that like this:
BEGIN
DECLARE #Results TABLE (Tid INT PRIMARY KEY);
INSERT #Results
EXEC Procedure2 [parameters];
SET #total 1;
END
SELECT #total
Your sp_test: Return fullname
USE [MY_DB]
GO
IF (OBJECT_ID('[dbo].[sp_test]', 'P') IS NOT NULL)
DROP PROCEDURE [dbo].sp_test;
GO
CREATE PROCEDURE [dbo].sp_test
#name VARCHAR(20),
#last_name VARCHAR(30),
#full_name VARCHAR(50) OUTPUT
AS
SET #full_name = #name + #last_name;
GO
In your sp_main
...
DECLARE #my_name VARCHAR(20);
DECLARE #my_last_name VARCHAR(30);
DECLARE #my_full_name VARCHAR(50);
...
EXEC sp_test #my_name, #my_last_name, #my_full_name OUTPUT;
...
You can call User-defined Functions in a stored procedure alternately
this may solve your problem to call stored procedure
Yes ,
Its easy to way we call the function inside the store procedure.
for e.g. create user define Age function and use in select query.
select dbo.GetRegAge(R.DateOfBirth, r.RegistrationDate) as Age,R.DateOfBirth,r.RegistrationDate from T_Registration R
Procedure example:
Create PROCEDURE SP_Name
#UserName nvarchar(200),
#Password nvarchar(200)
AS
BEGIN
DECLARE #loginID int
--Statements for this Store Proc
--
--
--
--execute second store procedure
--below line calling sencond Store Procedure Exec is used for execute Store Procedure.
**Exec SP_Name_2 #params** (if any)
END
I have a T-SQL stored procedure with the following parameters
CREATE PROCEDURE [dbo].[SaveData]
-- Add the parameters for the stored procedure here
#UserID varchar(50),
#ServiceID varchar(50),
#param1 varchar(50),
#param2 varchar(50),
#endDate datetime
AS BEGIN
.
.
-- my code --
I want know if it is possible to pass a result of select as parameter:
exec SaveDate (SELECT player.UserID,player.ServiceID, 'no','no',GETDATE()
FROM player)
I tried something like this, but it does not work.
1.One way is:
a) Declare your variables
b) Assign values to them with a single select statement
c) Execute the procedure passing the local variables
d) Execute the following in a loop using WHILE or CURSOR in order to apply this for all rows in TABLE1
DECLARE #param1 <DATATYPE>, #param2 <DATATYPE>, ...
SELECT TOP 1 #param1 = col1, #param2 = col2, ...
FROM TABLE1
WHERE <where_clause>
EXEC SaveDate #param1, #param2, ...
2.Other way is to define your own table type, fill it, and pass it to procedure. However this requires changing a little bit your stored procedure (in params list your custom type should be followed by READONLY):
CREATE TYPE [dbo].[TYPENAME] AS TABLE(
[ID] [int] NOT NULL,
...
)
GO
DECLARE #myTypeVar TYPENAME;
INSERT #myTypeVar
SELECT col1, col2, ...
FROM TABLE1
EXEC SaveData #myTypeVar
The SELECT query you wrote in your example would probably bring back multiple rows (your SELECT does not feature a WHERE clause or a TOP(n)). If your intention is to be able to have your procedure engage a "tabular" set of parameters, from SQL Server 2008, you are able to use table valued parameters.
This involves creating a user defined table table and will almost undoubtedly mean adjusting the logic inside the stored procedure.
Hope this helps :)

I've got two stored procedures:
SP1
CREATE PROCEDURE GetAge
#Birthday datetime,
#BirthDayAge INT OUTPUT
AS
SELECT #BirthDayAge = YEAR(GETDATE()-DATEPART(dy, #Birthday) + 1)-YEAR(#Birthday);
SP2
CREATE PROCEDURE AgeProc
#Age int
AS
DECLARE #BirthDayAge INT;
EXEC GetAge #Age, #BirthDayAge OUTPUT
SELECT ... FROM ... WHERE #BirthdayAge = #Age;
For some reason or other, no results are being returned in the second procedure when tested. Am I doing something wrong in either of the stored procedures?
WHERE #BirthdayAge = #Age;
you are comparing 2 variables.
Shouldnt one of this be a table column?
also, you are passing an integer to a datetime, that may cause issues
