[Qt-interest] Driver not loaded...

[Jason H]

Sqlite has the anti-thread documentation. Paraphrased, "threads are evil"
Sqlite can handle multi-process locking through.

Threading support is left up to the driver.

I actually did read the section on threads and databases and nowhere in there 
does it say anything about the instance of the database having to reside on the 
same thread that the database is opened. That is why I suggested they add the 
documentation. But, like Scott said, it is probably something different with the 
driver, so I could see how it would be difficult to document all databases and 
their special characteristics. Thank you for your reply!

Hello All,
 
I have an application that uses an SqLite Database. I can open the database just 
fine, write to it, and read from it without problems in most cases; however, 
when I try to open the database on a different thread than the one that it was 
created on, I always get an error. And the error always says that the drive ris 
not loaded. Can anyone tell me why this is happening? Or what I can do to fix 
it? According to the documentation, threading should not be a problem.
 
There is actually a documentation section about threads and sql databases. You 
might want to take a look.
