How to store a pdf file in a BLOB field of SQLITE ?

[Chris Holbrook]

can I reuse parts of your code ?

certainly, at your own risk!

ISTR that the application loads a blob from the DB then puts it into a temporary file from which GDI+ loads it, so the code you need may already be there.

Edwin and Chris, thank you for your answers.

Chris, I looked at your application. It is almost what I need; can I reuse parts of your code ? I just need to add a new option to re-create the jpg file directly after reading the image from the blob field (loadfromDB() function): not sure if I have to use the function readblob() or if can save the data right after the query when the image is in the buffer.

I recently posted a SQLite image blob example in the source code forum, if that helps?

You can bind to a blob field but the simpliest is to convert the PDF to hex.
Then insert with X'your hex data here'
The data will be stored as the original (1:1), not as hex.

I am having trouble figuring out how to successfully write a pdf file and/or image (jpg) to the SQLite database as a Blob, using PowerBASIC.

How can I retrieve the pdf file and/or image (jpg) later from the BLOB field of the SQLite database ?

I'm looking for sample PowerBASIC code.

Thank you for your help.
