Question

How to return 1 if username exists and 0 in other case? Here is what I’ve tried.

IF EXISTS (SELECT * FROM [User] WHERE UserName = @UserName and EmailID=@EmailID) 
    begin
      return 1;
    end
     else
      begin
    declare @CreatedOn datetime
    select @CreatedOn = getdate()
    insert into [User](UserName,Password,EmailID,ContactNo,CreatedOn) values(@UserName,@Password,@EmailID,@ContactNo,@CreatedOn)

Maybe you could try this query:

Select count(*) from [user] where  UserName = @UserName and EmailID=@EmailID

and if user name exists count(*) will be larger then 0
