从MS访问到包含MySQL的图片导出表（BLOB）

Question

i have a database table in MS-ACCESS format (MDB) containing structure as

Form_No   Int
Picture   OLE OBJECT

when i import this table in MySQL using navicat, then the PICTURE field converts to BLOB and the field has no images(IMAGES ARE LOST). what to do ?

Answer 1

OLE objects are tricky beasts - it is not exactly trivial to convert them into pictures.

This article is an example of C# program (about 5KB) that can convert OLE object to few supported formats (JPEG, BMP, PDF, WORD).

You should be able to adapt it to your needs. I would think it will be easier to create new BLOB picture column in MS Access table first, convert it to real JPEG (not OLE!) using C#, and only then export it to MySQL.
