This sounds strange.  I can connect to many tables in less than a minute. 
 I can open tables in seconds regardless of how many rows are in the 
tables.  Access usually only selects 20-30 rows at a time.  My ODBC 
connections to PostgreSQL in Access are fast.  Not as fast as opening local 
Access tables by much faster than 1 minute.  You can try different options 
in your connect statement.  Some options work with ODBC, others don't.  If 
this does not help, you will have to email me your VBA code.

thanx for the answer.
i have in every table a primary index called ID, but ODBC and VB don?t
accept it as a primary keys. and the performance of the OBDC connection
is rather bad. he needs almost 1 minute to connect to a table with 300k
rows, for just appending a few lines. even sql calls fails. i postponed
the whole transfer for a time and check it then again.

but thanx for the reply
