Hi Paul,
You said:
|Someone tell me why this isn't working. It's annoying me now:
|
|
| SELECT 'name not given', *
| FROM Directory
| WHERE CountryID = @country
| IF ( @type IS NULL )
| BEGIN
| AND DirectType = @type
| END
SQL doesn't support IS NULL like this.
In my experience you have to use the ISNull() function.
usage:
ISNULL(check_expression, replacement_value)
The replacement_value argument is the value the field will have, replacing
the NULL value, when the field has a NULL value.
AN example:
SELECT 'name not given', *
FROM Directory
WHERE CountryID = @country
IF ( ISNULL(@type,'ANULL IS HERE') = 'ANULL IS HERE' )
BEGIN
AND DirectType = @type
END
Hope this helps.
