SQL query does not work every time

[wysota]

The database may fail to open if the killed process did not release a lock on the sqlite file. Are you also using QSqlDatabase::removeDatabase()?

Carefully read the description of the QSqlDatabase::addDatabase method. You have to use the second parameter.

Thanks, I was not using the connection name parameter (neither QSqlDatabase::removeDatabase()) so each time client contacted again it tried to use the same default connection and it failed. Now I'm using clients username to differentiate the database connection name. Seems to work.

Cheers guys!
