Question

I want to create a procedure that takes in a string, searches the table and the specified column for that string, and returns a 1 if it finds it and a zero if it does not. I am relatively new to SQL and do not know the syntax or commands very well. I want something like this:

CREATE PROCEDURE dbo.GetUsername

(
@Username   NCHAR(10)
)

AS   
    @boolVariable
SELECT  @Username FROM Accounts  
RETURN  @boolVariable

Answer 1

You don’t return a value, but instead supply that in a result set.

CREATE PROCEDURE GetUsername
(
   @Username   NCHAR(10)
)    
AS       
    SELECT Username FROM Accounts WHERE Username = @UserName;

In your calling code, simply check for the existence of a row in the result set.
