Description:

Hi.
Please explain me.
I use psqlodbc to do my work at university. I need to develop an
application to access the Postgresql database. I am using the QT development
environment. When doing the work, I need to use fields like bytea. But when
working with bytea, I get this error : QSqlError("7", "QODBC3: Unable to
execute statement", "ERROR: type \"lo\" does not exist;\nError while
executing the query").
It is a mistake to add a picture to the bytea field. I don’t understand why
to me told about type "lo", because I set the bytea type .
This error appears when using the psqlodbc driver.
