Question

i have an SP where i need to check for if condition

ALTER   PROCEDURE [dbo].[spCheck]  
 @strEmpname  VARCHAR(50),  
 @intReturn  INT OUTPUT,
 @intWorkdID  INT,
 @intEmpID INT  
AS  

BEGIN  
IF(@intWorkdID is not null and @intWorkdID != '')
    BEGIN 
      IF EXISTS ( SELECT *   
          FROM Employee   
         WHERE [Empname] = @strEmpname   
         AND WorkID = @intWorkdID 
           )  
       SELECT @intReturn = '1'  
    END 
ELSE    
IF(@intEmpID is not null and @intEmpID != '')
   BEGIN
     IF EXISTS ( SELECT * 
          FROM Employee   
         WHERE [Empname] = @strEmpname    
         AND PeopleID = @intEmpID 
           )  
       SELECT @intReturn = '1'   
    END
 ELSE IF(@intEmpID is not null and @intEmpID != '') 
 and(@intWorkdID is not null and @intWorkdID != '')
  BEGIN  
   SELECT @intReturn = '0'  
  END  

END  

here based on WorkID,EmpID
1 condition and 2 condition should execute

if both condition fail i need to excute the third condition

can any one tell the syntax for it

thanks

Best way is that you can use

Try something as below:

SELECT @intReturn = 
     CASE
          WHEN @intWorkdID IS NULL THEN 1
          WHEN @intWorkdID<>'' THEN 1
          WHEN @intEmpID IS NULL THEN 1
          WHEN @intEmpID <>'' THEN 1
          ELSE 0
     END

Case… When
