incorrect syntax near '=' error on sql server

Question

I am using just creating PROCEDURE and calling the procedure.

CREATE PROCEDURE ActiveUser @UserID int
AS
SELECT * FROM UserInfo WHERE UserID = @UserID;

EXEC ActiveUser UserID = "1"

But get this error

Incorrect syntax near '='

Answer 1

Actually correct syntax is

If you direct calling this:

    EXEC ActiveUser 1

or

    EXEC ActiveUser @Userid = 1

Or if by passing parameter

  declare @par int = 1
  EXEC ActiveUser @par
