I changed from Access97 to AccessXP and I have immense performance
problems.

Details:

- Access XP MDB with Jet 4.0 ( no ADP-Project )
- Linked Tables to SQL-Server 2000 over ODBC

I used the SQL Profile to watch the T-SQL-Command which Access ( who
creates the commands?) creates and noticed:

1) some Jet-SQL commands with JOINS and Where-Statements are
translated very well, using sp_prepexe and sp_execute, including the
similar SQL-Statement as in JET.

2) other Jet-SQL commands with JOINS and Where-Statements are
translated very bad, because the Join wasn´t sent as a join, Access
collects the data of the individual tables seperately.
Access sends much to much data over the network, it is a disaster!

3) in Access97 the same command was interpreted well

Could it be possible the Access uses a wrong protocol-stack, perhaps
Jet to OLEDB, OLEDB to ODBC, ODBC to SQL-Server or
Jet to ODBC, ODBC to OLEDB and OLEDB to SQL-Server instead of
Jet to ODBC and ODBC direct to SQL-Server

Does anyone knows anything about:

- Command-Interpreter of JetODBC, Parameters, how to influence the
command-interpreter
- Protocol-Stack of a Jet4.0 / ODBC / SQL-Server application

Thanks , Andreas
