Not enough space on temporary disk - why not?

Not enough space on temporary disk - why not?

Post by VENT » Thu, 16 Mar 2006 01:56:13


I'm trying to run a query, but getting this error:

"Not enough space on temporary disk."

I don't understand why. I have 5+ gigs on my C: drive, and 18+ gigs on my
D: drive. I've looked this up in help, and found that this refers to my
"TEMP" variable in DOS. Mine is on my C: drive, currently using just over 2
gigs (2,097,152 KB), and leaving me the 5+ gigs still available. So what's
the problem? I do know that the .mdb limit is (or at least *was*) 2gb. But
this is a "temp" file, not an mdb.

What am I missing?

Thanks in advance,

Tom

Please post the SQL of the query and the approximate number of records in any
tables involved.

Also have you compacted and repaired your database lately? How big is it
before and after compacting?

I'm querying a DB2 db on an AS/400. Something I do all the time. Admittedly,
in this case I'm going to get back a lot of data, a year's worth of trans for
all active customers. (Roughly 18k customers * 8 trans/cust (approx) * 12
months.)

ooks like the tables are properly joined as seen below so that there isn't
an outright Cartisian product. However you really don't know if there are
multiple joins between the fields unless one side is the primary key. You
might have a mini cartisian product happening.

tblAnnRptFY05a_EL LEFT JOIN tblCXLIB_UT420AP ON
(tblAnnRptFY05a_EL.[Cust ID] = tblCXLIB_UT420AP.UTCSID) AND
(tblAnnRptFY05a_EL.[Loc ID] = tblCXLIB_UT420AP.UTLCID);

Next you are doing a DISTINCT which will take a lot of temporary space to
weed out any duplicate records. It might be best to first create a make table
query without the DISTINCT then insert the records from there.

Lastly I don't know if a DB2 db on an AS/400 supports it, but a Pass-through
query would be a lot better if possible. Instead of bringing all the data
into Access, let the DB2 database do most of the work for you. In the case of
other databases, like SQL Server, pass-thru queries are much more efficient.
