Goal
You have an Oracle Database Table containing BLOB data and a column which keeps name of the file for that BLOB Data. You want that each BLOB data is saved to Physical Files with names as stored in "File Name" Column. This Documents details how to achieve this goal.
Prerequisite:
-----------
Consider a sample data as:
Table1
---------
filename FileContent
myfile1.pdf BLOB1
myfile2.pdf BLOB2
myfile2.jpg BLOB3
After running Export Wizard from SQL Developer, it should produce:
myfile1.pdf --> containing BLOB1 content
myfile2.pdf --> containing BLOB2 content
myfile3.jpg --> containing BLOB3 content
It is then assumed that BLOB content matches with the filename extension. For example BLOB1, BLOB2 are PDF format content and BLOB3 is an image content.
Script does not verify the content and assumes they are mapped correctly.
Disclaimer:
-----------
Please note:
This sample python script is for a Demonstration purpose only. This is not a part of SQL Dev product and not supported.
This is more like post processing with a workaround. You need to enhance script or choose any other alternative to achieve it.
There are other option such as running JavaScript from SQLcl.
