requested database does not belong to the calling thread

[nn26]

Hello,

I am getting this error.

QSqlDatabasePrivate::database: requested database does not belong to the calling thread

In my application with database, I have 5 tables. I am using two tables with one thread (with plugins to application) and another three tables with second thread from same application.

is this a problem due to same connection name for both thread? or something else?

thanks.

You can only access a QSqlDatabase from the thread which created it/in which it lives.

Hi,

You need to create one connection per thread directly in the thread where you will use it.

[nn26]

QSqlDatabasePrivate::addDatabase: duplicate connection name'xxx', old connection removed

so this is creating problem right?

@nn26 Don't use same connection name more than once

Give each thread's connection a unique name. You can use the thread id for that for example.
