The following example returns the SIGN values of numbers from -1 to 1.
DECLARE @value real
SET @value = -1
WHILE @value < 2
BEGIN
SELECT SIGN(@value)
SET NOCOUNT ON
SELECT @value = @value + 1
SET NOCOUNT OFF
END
SET NOCOUNT OFF
GO
"The @CustID means it's a parameter that you will supply a value for later in your code. This is the best way of protecting against SQL injection. Create your query using parameters, rather than concatenating strings and variables. The database engine puts the parameter value into where the placeholder is, and there is zero chance for SQL injection."
