Обсуждение: Access 97 - problems with the result set

I am running access queries and it seems that it thinks certain queries were
unsuccessful when in fact they were successful...!

Is there something special that access expects to get back which indicates a
successful query?

Of course access appends the horrid select * from to the front of the query
and then postgres promptly gives and error.

Access then reports an error. Even though the original query executed fine
on the server.

Postgres 7.1.2
odbc 7.01.0006
win2k is the client


respectfully,
Joseph

Answering my own question, partly...

Turns out access seems upset at least some of the time if
there are no REAL fields returned from the database.

So if we have a table foo with a field  f1
and
we query it this way - SELECT 't' as t from foo
there is no error on postgresql but access first runs the query as is then
tries 'SELECT * FROM SELECT 't' as t from foo' which causes an error on
server, and therefore the error on access.

Any thoughts about how to fix this other that doing adding a REAL field so
it dosen't fail
as - 'SELECT 't' as t,OID from foo' (which works fine).

Hello,
    Couldn't you just do select 't' as t ? This seems to work on MS
Access2K. If you are (for whatever reason) actually wanting to execute the
query on the server instead then try a pass-through query (note:
pass-through queries only return snapshot recordsets).
