:) Yes you got that right or: Danke, es geht mir gut. with a little
headache because the below described trouble ;-)

don't know if I got that right; I'm enclosing the query-criteria; see:

Select Groessen from Weg where Bsnr = '14957' and Znr = '1' and
wegkz => '1'

I think, that the problem is, that field "groessen" is defined as fieldtype
text;
I created a separte table where field groessen is defined as varchar(65535)
(I'm porting an MS-Access-Application and in Access this field is a
memo-type)
and it works perfect;

? do I have to configure the ODBC-Driver: no check on "Text as longvarchar"
???

best regards
Wolfgang
