Re: PgSQL vs Ms.Access slow in search - Mailing list pgsql-odbc

Edit the ODBC driver DSN that you are using to connect to PostgreSQL and
turn on or enable the "CommLog" option.  It can be found by clicking on the
"Driver" button.  Try your search in Access again.  This should create a
file in the C: drive of the PC you are running Access on called
c:\psqlodbc????.log where ???? is a number.  If there are many of these
types of files in your C: drive, the select the latest file and review it's
contents.  This should show everything that happens between Access and
PostgreSQL.  This log file has helped me resolve 90% of my issues with
Access.   If it is still unclear what the problem is, then please email the
log file.

Subject:    [ODBC] PgSQL vs Ms.Access slow in search


Hello everybody!

    First of all, sorry for my poor english. And now, the problem
that don't leave me sleep :). I'm using PgSQL as the data source of some
forms in MsAccess, with the current version of the ODBC driver. It
exports/imports tables right and fast. But... when I have the tables
"linked" (it's correct this word???), and i try to do a search (Edit->Find
or Ctrl-B) in any column of any table with more of 1.000 tuples:
 first: the access seems to be dead thinking too much :)
 second: the postmaster takes 99% of CPU
Why????? In numerics primary keys, the both works better, but most of
time, they dead.

I've startde postmaster from a shell, and I get:
2001-10-09 20:39:50 [6573]   DEBUG:  StartTransactionCommand
2001-10-09 20:39:51 [6573]   DEBUG:  CommitTransactionCommand
2001-10-09 20:39:51 [6573]   DEBUG:  StartTransactionCommand

2001-10-09 20:39:51 [6573]   DEBUG:  StartTransactionCommand
2001-10-09 20:39:51 [6573]   DEBUG:  CommitTransactionCommand
2001-10-09 20:39:51 [6573]   DEBUG:  StartTransactionCommand
2001-10-09 20:39:52 [6573]   DEBUG:  CommitTransactionCommand
(only 4 querys from each second?????)

I've tried to fin a solution by my self, but I couldn't :(. With MySQL ->
MyODBC -> Access the problem It's the same.

Thanks in advance from Spain...
