ODBC and Union Queries

Posted on 2001-07-23
Last Modified: 2008-02-01
Ok, I have 3 tables  1) New, 2) Current, and 3) History.  All 3 have identical data structures.  I am trying to do a Union query in Access, but I get the following error:

ODBC--call failed.
[Timberline][Timberline ODBC Dri(#0)[Timberline][Timberline ODBC Driver](#0)

The funny thing is I can get the query to work fine in Crystal Reports SQL Query Designer.  I have tried to restart everything, kicked everyone out of the DB, Refreshed the links to the Timberline tables, yet nothing works.  Any ideas?  Below is my code, notice how terribly basic it is...

-instead of using *, have you tried replacing it with the actual field names???
-i assume the ODBC driver is the "latest", correct?

just some thoughts...

Yes, I started with just one field name and reverted to the * hoping it would alleviate any errors.

What is weird is that it DID work...once.  Then I started changing it to exactly what I wanted and stopped working.  It makes no sense.  Also, it does work in Crystal SQL, just not access.

ok. we'll put it to the test then! :)

i am assuming that your query is based off of "linked" tables, right?  instead, use a passthrough query. passthrough queries are run DIRECTLY against the server with no (very little) Access manipulation.

if you need help with creating a passthrough query, let me know. otherwise, try that and see what happens.

I've never done a pass through, and the documentation is not very good.  Any chance I could get an example to run off?  I'm assuming this will allow me to plug the information where I want it, but will it let me do a union as well?

Btw, thanks so much for the help.

Just change the query typr to pass thru from the query menu and selecting SQL specific .

devtha is mostly correct. you need to be careful with your syntax when running a passthrough query as you will need to use ansi sql as opposed to access sql. so getting the syntax just right might take effort.

but to try it out, you create a new query. go to the query menu, choose "Sql specific" and then choose "pass-through".  you will be forced to TYPE in your sql, so as a trial try something like "SELECT * FROM SomeTableName" and then run the query to see if it works.

oh yes, union is an ansi sql command, so that should work fine...

good luck, let us know if you need any more help.
