In this article I will explain with an example, how to assign (set) result value of EXEC function to Variable in SQL Server.
The capturing and assigning result value from EXEC function to a variable is supported in SQL Server versions i.e. 2000, 2005, 2008, 2008R2, 2012, 2014 or higher.

Here I am making use of Microsoft’s Northwind Database. The download and install instructions are provided in the following article.

Stored Procedure that returns value
In order to illustrate the process of assigning result value EXEC function to Variable in SQL Server, the following Stored Procedure is used which returns an Integer value 1 if the EmployeeId exists and 0 if the EmployeeId does not exists.
CREATE PROCEDURE CheckEmployeeId
      @EmployeeId INT
AS
BEGIN
      SET NOCOUNT ON;
 
      DECLARE @Exists INT
 
      IF EXISTS(SELECT EmployeeId
                        FROM Employees
                        WHERE EmployeeId = @EmployeeId)
      BEGIN
            SET @Exists = 1
      END
      ELSE
      BEGIN
            SET @Exists = 0
      END
 
      RETURN @Exists
END
 
 
 
Fetching returned value from EXEC function
In order to fetch the returned integer value from the Stored Procedure, you need to make use of an Integer variable and use along with the EXEC command while executing the Stored Procedure.
