BLOB issue with Assign

Post by cbc700 » Tue 22 Nov 2011 06:23

I have a freshly allocated TVirtualTable instance and I assign to it a TUniQuery with 4 fields, one of them being a BLOB column with bitmaps. 3 if the fields are broght over fine, but the BLOB is not. Upon using SaveToFile or SaveToXML, it's evident that the schema information is present for all fields, with the data being present only for the 3.

Should this be working or might this be a known issue?

Using Delphi 2010 with UniDAC 3.70.0.19.

Thanks.

Hello,

I cannot reproduce the problem.
Data from BLOB fields of VirtualTable (image) is saved and loaded to/from file correctly. Try to download the latest UniDAC version 4.0.2 and reproduce the problem. If the problem persists, please send a sample reproducing the problem to alexp*devart*com.
