Hi Winthor;

   The key here are the PB commands UpdateBlob() & SelectBlob(). The SS column type would be "Image".

Regards ... Chris

this is the script that I am working on...but it is not working...no data saved to the database











long ll_file, ll_bytes, ll_pdf_key = 1

blob lblob_file





ll_file = FileOpen("C:\AFFC\otia.pdf", StreamMode!)

ll_bytes = FileReadEx(ll_file, lblob_file) /* ll_bytes value is 7982565*/

FileClose(ll_file)

if ll_bytes > 0 then





Updateblob dat_pdf

set files = :lblob_file

where dedcode = '1H1'

commit SQLCA;





end if

if I remember correctly,autocommit must be set to TRUE before UPDATEBLOB.



HTH.

Hi Philippe,

I think you're right for MS SqlServer, but not for all Databases like Oracle.

Have you confirmed that the row exists in dat_pdf before you execute the UPDATEBLOB command?

Hello,

Here is a sample program to upload pdf file and save it to a SQL Server database.  I've attached PB 2019 R3 project (in zip file) with structure.sql file to create the table.  

Modify the database credentials at application open event.

HTH

Happiness Always

  • What's the type of the "files" field in your "dat_pdf" table?
  • What error text can you see in sqlca when the update fails?
