Execute a stored procedure in another stored procedure in SQL server - sql

Question

How can i execute a stored procedure in another stored procedure in SQL server?
How will I pass the parameters of the second procedure.?

Answer 1

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.

Answer 2

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

Answer 3

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

Answer 4

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;
...

Answer 5

You can call User-defined Functions in a stored procedure alternately
this may solve your problem to call stored procedure

Answer 6

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

Answer 7

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
