Solution 1

Have a look,

Sql Count.asp[^]

Sql where[^]

So the logic will be ,

C#

if( SELECT COUNT(*) FROM YOUR_TABLE WHERE USERNAME=USER_INPUT_USERNAME > 0 ) then
 do something
else
 No such user exists

Hope it helps :)

for the stored procedure you can use

SQL

CREATE PROCEDURE [dbo].[SE_SelSecUserCredentials]
	@UserName	NVARCHAR(45),
	@PassWord	NVARCHAR(45)
AS
begin
	SELECT
		 thefiels or count you need
	FROM 
		UserTable
	WHERE 	loginName = @UserName
	AND	BINARY_CHECKSUM(password) = BINARY_CHECKSUM(@PassWord)
end

We do a Binary_Checksum on the password to keep up with capitals in the password. a lower case for a capital will not give you a result (a in binary is different value than A)
