Using MySql 5.0.13 ODBC 3.51 and MS Office 2k3

I have 2 table 
  `identr` int(10) unsigned NOT NULL auto_increment,
  `APE` text NOT NULL,
  `RS` text NOT NULL,
  `siret` text NOT NULL,
  `adresse` text NOT NULL,
  `CP` int(10) unsigned NOT NULL default '0',
  `Ville` text NOT NULL,
  `Tel` text NOT NULL,
  `Fax` text NOT NULL,
  `www` text NOT NULL,
  `Email` text NOT NULL,
  `Groupe` text NOT NULL,
  `Nationalit` text NOT NULL,
  `Effectif` decimal(10,0) unsigned NOT NULL default '0',
  `Qualification` text NOT NULL,
  `Civil_res` text NOT NULL,
  `Nom_res` text NOT NULL,
  `Function_res` text NOT NULL,
  `juridique` text NOT NULL,
  `cedex` text NOT NULL,
  PRIMARY KEY  (`identr`)

this table as about 13000 records

  `Ville` char(100) NOT NULL default '',
  `CP` int(5) unsigned NOT NULL default '0',
  `zone` int(10) unsigned default '0',
  PRIMARY KEY  (`CP`,`Ville`)

and this one about 400 records

and one view
LEFT JOIN CP on CP.cp=CRCI.cp and CP.Ville like concat(CRCI.Ville,"%")
WHERE CP.zone=3;

witch hit about 300 records

And all is ok from my linux box

How to repeat:
And now the funy part 

I've made a DSN for my database using options "Allow big result" and "Use Compressed protocol"

When I import data from zone_ASud into Excel via ODBC, I have 300 records and all is ok ! Idem from word!

When I import (or link) same datas (zone_ASud) into Access via the same ODBC connexion, I have 14000 results ie all rows from CRCI table and no error!

I am now facing this problem! MyODBC5 does not work at all - it does not get any data.

So is there a solution for MySQL5 and ÓDBC 3.51?

What's the status regarding this issue?
I tested MyODBC 2.51.13 but the problem is still there.

Still facing this problem with MS Access 2003, MyODBC 3.51.12 and MySQL 5.0.22. It makes the long awaited views totally unusable for those poor fellows who use Access as the front-end to the data. Well, that's alright (though views could make developers life much easier in many cases). What worries me much more is that in this case the server returns more data via a view than expected. It is like if Access and MyODBC define a completely new view which is not aware of the criteria (like WHERE privilege>0) of the original view saved in MySQL server. Isn't that a bad thing? It seems to be pretty much of a security issue as well if someone (on the server side) uses views to restrict data access and neat users with MS Access and MyODBC can get much more out of it. 
So how can it be only the bug in MyODBC? Aren't there some problems on the server side too?

It is a problem in the client library.
See bug #19671. Its priority has been increased to high.

This was a server problem which was fixed in MySQL 5.0.25.
