A common approach is to use a TBlobStream. Lookup the help on TBlobStream. When the object is created, you associated it with the blob field of a dataset.

Then you can save data directly to the stream, using methods like TJpegGraphic.SaveToStream, or any other graphic class that can save to a stream. Note that you should also save the type of graphic, ie, extension in the database, so you may later read it back properly.

Note that Envision 2 can detect the format from the contents of the stream, but if you are using other classes, it would be safer to save the extension also in the table.

Best regards,
