How to use the path (database file)  of a datasource in a SQL query.

I have query like this
<CFQUERY NAME="SAV1" DATASOURCE="usertables" dbtype="ODBC">
INSERT INTO USER(WEBPAGEID,COUNTRYID)
IN 'D:INETPUB\WWWROOT\DATABASES\CAWS1.MDB'
SELECT WEBPAGEID,COUNTRYID
FROM USERCONFIG_S
WHERE .....
</CFQUERY>
User is a table in a different database CAWS1.MDB and I use the query to insert the records in it hardcoding its path as shown above.
As CAWS1.MDB is a datasource ,I was wondering if its path as given in Database file field of the Administrator section can somehow be used so that I donot have to hardcode the path.
Is there any other way.
Thanks
AA

hi aa, creating a dsn without odbc is like this

<cfset DBPath="D:INETPUB\WWWROOT\DATABASES\CAWS1.MDB">
<cfquery name="QueryName"
 datasource="#DBPath#"
 dbtype="OLEDB"
 provider="yourprovider"
 providerdsn="#DBPath#"
 username="Admin"
 password="">

but what u r doing i think is not possible, meaning in one cfquery , trying to so a select and insert into another different database..board is quick - so u can wait to see answers..

cheers.

As we know every datasource is associated with a database file which is the path for the file.Is it possible to save the path for a datasource in a variable.i.e CAWS is a datasource and has a path associated to it .can we store the path for the CAWS datasource using some colf fusion function etc.
Thanks

Simple, centralized multimedia control

Watch and learn to see how ATEN provided an easy and effective way for three jointly-owned pubs to control the 60 televisions located across their three venues utilizing the ATEN Control System, Modular Matrix Switch and HDBaseT extenders.

Ahson sorry
simply use the
fileexists() to check if the file is available and directoryexists() to see if the directory is available..

cheers.

Thanks But I think I confused you.
suppose we have a datasource = "Caws".Can we store the path to this datasource in a variable that could be used in a query.
Thanks again
AA
like
<cfset my_path=some function getting the path for datasource CAWS1.mdb>

<CFQUERY NAME="SAV1" DATASOURCE="usertables" dbtype="ODBC">
INSERT INTO USER(WEBPAGEID,COUNTRYID)
IN '#my_path#'
(instead of
IN D:INETPUB\WWWROOT\DATABASES\CAWS1.MDB')

SELECT WEBPAGEID,COUNTRYID
FROM USERCONFIG_S
WHERE .....
</CFQUERY>
Thanks

Ah, no you cant do that , better do

<cfquery name="lastquery" dsn="olddsn">
SELECT WEBPAGEID,COUNTRYID
FROM USERCONFIG_S
WHERE .....
</cfquery>

then
<cfoutput query="lastquery">

<cfquery dsn"newdsn" query="newquery">
INSERT INTO USER(WEBPAGEID,COUNTRYID)
VALUES(#lastquery.webpageid#,#lastquery.countryid#)
</cfquery>

</cfoutput>
