Retieve BLOB data from DB for i gets converted

[bvv400]

THE BUG
IBM i DB table column as BLOB data which contains the contents of a JPEG file gets converted when using the bwicompanies/db2-driver in an IBM i V7r4 Seidon PHP Laravel 11 app.
The same app on a Linux RHEL 8 with a Oracle DB driver does not convert the JPEG data.

The data in the IBM i DB table BLOB is a copy from the Oracle DB and is binary the same when both columns are compaired.
(See Check with DB viewer )

To Reproduce
Store a JPEG picture in a BLOB field, retieve the data in a Laravel 11 controller field, print Header information en echo the content of the picture to a Browser session .

Expected behavior
BLOB data should not be converted when retieving it with the db2-driver

@bvv400 Just curious - have you tried this as a clob? The laravel migration column type would be text

@bennettblack .

I think the problem is in the Linux distribution of the ODBC accesses for IBM i.

On de CLOB I had the following problem. On the LINUX host retrieving a CLOB from the IBM i DB gave a problem of two bytes loss around the border of the first 256 bytes.
On the IBM i the CLOB was presented correctly.

We made the decision to extract the BLOB data from the Oracle DB to a file in a directory and copied that directory to the IBM i. The program now retrieves the file for IFS.
So we use no BLOB data anymore in the IBM i DB.

For the CLOB we decide to stay on the IBM i DB while on that DB there are no longer updates.

So for us the issue has been solved by management decisions rather then bug fix.
