Descombes Guest Posted: Wed Oct 18, 2006 7:37 pm    Post subject: What is the maximum number of columns supported by ADO Hi, I tried to read a csv file which has 320 columns, ADO only reports the first 256. Is this a known limitation? Is there a way to overcome it?

Also be ready that even those 256 columns could be messed up. Quote: Is there a way to overcome it? Same limitation exists with MS ODBC text driver, however maybe there is some 3pds drivers out there. Back to top Andre M.
