Question

I’m working on a faceted search in Coldfusion and SQL. I’ve tried creating a query like this:

SELECT * FROM Turbos 
WHERE
  PartNumber LIKE '%#trim(SearchCriteria)#%' 
  OR PartDescription LIKE '%#trim(SearchCriteria)#%' 
  AND (PumpingSpeed BETWEEN #minimum# AND #URL.speed#) 
  AND InletFlange LIKE '#URL.inlet#' 
  AND Bearing LIKE '#URL.bearing#' 
  AND Condition LIKE '#URL.condition#'

The problem is the server is returning rows that don’t contain EVERY piece of data I’m supplying. How can I select ONLY those rows which contain all the criteria?

Answer 1

just wrap the OR bit in brackets:

(PartNumber LIKE '%#trim(SearchCriteria)#%' OR PartDescription LIKE '%#trim(SearchCriteria)#%') AND...

at the moment you have A or B and C which is being read as A or (B and C). You want (A or B) and C.

And make sure you use cfqueryparam as suggested above.
