Are you talking about columns of data type BLOB? The word 'attribute'
confuses me.

There is plenty of information about BLOB in the manuals.

I am not sure what you mean by an 'sql database', but if you're talking
about a MySQL database, consider using the 'SELECT' command.

If you encounter any problems, describe them in detail, maybe somebody
can help you.

Yours,
