I'm not following the logic here. Let me reword this:
WHERE @passedValueCity IS NULL or dbColumnCity LIKE @passedValueCity
So my new query looks like this:
SELECT listing_id, RANK, name, address, city, zip, heading, phone
FROM listings a,
FREETEXTTABLE(listings, *, @Search)
WHERE [KEY] = a.listing_id AND (@passedValueCity IS NULL or dbColumnCity
LIKE @passedValueCity)
ORDER BY RANK DESC, name
I altered my query as such, and it returns no resluts either way - if
passedValue has a value of if it doesn't. (it also doesn't work if I
take off the () around the new AND clause.)
I hope I am making sense.
Thanks,
Casey

WHERE @city IS NULL OR city LIKE @city
