Thanks for the info, will have to experiment and see what happens -----Original Message----- From: Bryan Stevenson [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 11, 2003 12:30 PM To: CF-Talk Subject: Re: DSNless connection
Sam Neff posted this a while back for me....haven't tested, but I'll betcha it'll work: Sam Neff said: As earlier posters stated, DSN-less connections are no longer directly supported in CFMX because they are not supported in JDBC. However, there is an easy work around. Jet (MS Access database engine) supports a special use of the IN keyword in the FROM clause of a query to specify another source database. The secondary source can be a Jet (Access) database or any Jet accessible source (Excel, DBase, Text, etc.) or any ODBC connection (dynamic connect string). To set this up create an empty Access database and then create a datasource for this database named "PassThroughMDB". Then you can run queries like: <cfquery name="getFromDynamicConnection" datasource="PassThroughMDB"> SELECT * FROM some_table_in_another_db IN 'c:\wherever\other_database.mdb' </cfquery> You can experiment with paths to an MDB, XLS, etc. or you can use an ODBC connect string. To use ODBC I believe you have prepend it with ODBC; as in FROM wherever IN 'ODBC; [dynamic odbc connect string]' See MS Access help for more information. You can also view some examples in MSDN Library. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/off2000/htm l/acsqlINX.asp Another option is to create linked tables in the Access database. I know you can do this with DAO, and you may be able to do it with some combination of ADOX/JRO or even with DDL through CFQUERY. If using MSSQL or Oracle (and if so why would you need a dynamic connect string?) you can use linked databases (perhaps they use a different term, but the concept exists in both). Good luck!
