mysql row search
I have a table:
Table Keywords
id,keyword
Here is sample data
1,test1
2,test2
3,test2
4,test3
5,test4
1,test5
1,test6
2,test7
3,test8
2,test9
Let's say I want to get ID's where keyword is test5 and test6, but I want the ID number has to be the same.
ie if I did a search for test5 and test6 keywords it would return 1 because that is the only ID that matches the keywords
Any ideas how I would do this?

I want to do a search on the table and if I do a search on two keywords test5 and test6 (from my example above) if the ID is the same for both of the keywords found I want to return the ID.
Test5 and test6 both have the same ID in my table data above so the ID would be the same
Here is what I want
Select all IDs from keywords table where a row.keyword = test5 and a row.keyword = test6 and each row has the same ID.

You would substitute your form variables, or whatever for the test5 and test6....
where keyword = <cfqueryparam value="#trim(form.field1)# ">
or keyword=<cfqueryparam value="#trim(form.field2)# ">
Building up the criteria in the where clause would be by whatver means is applicable.
The important point is to get all the entries for the keyword... group by id, then filter the list where the count(*) > 1... meaning that more than one record was found for that id that matched the keywords.

having works like where, but works on the grouped records.
<cfquery name="findRecs" datasource"yourDSN">
select distinct id
from yourTable
where keyword like 'form.input'
</cfquery>
<cfif findRecs.recordCount gt 1>
<cfset form.errorMsg = "keyword matched more than 1 result. refine your search">
</cfif>
