Description:
We have a problem with mysql and varchars of less than 4 chars when using a linked server through MyODBC in MSSQL 2K. MS Access works as expected. 

How to repeat:

in mysql:

create table ctest ( c1 varchar(2), c2 varchar(20) ); insert into ctest values ('a','b'),('c','d');

in sql2k, create a linked server using myodbc and then run:

select * from ctest

.. that will reproduce this error.
