ODBC extraction - null values instead of DB values

[#1]

Hi all,

I have some trouble with some data extractions using ODBC connection in QV.

In my application, i've configured delta extractions (by year) for my datas. After the "extraction" process I've lost some values for certain fields (values are null instead of having the database values). I don't understand what happen,

I've searched on web about ODBC and buffering configuration into QV without results, do you have any idea ?

Regards,

Kévin

Export some data to excel and as a test retry the procedure with the excel files. I'm pretty sure it has nothing to do with ODBC. Then if you still have the same problem, post the excel files and the qlikview file here. That way we can have a look at what you're actually trying to do.
