How to get signal of qsqldatabase?

Question

I want signal emitted by qsqldatabse object

Eg: I have Qsqldatabase db;

connect (&db, SIGNAL(signal_like_exec()), this, SLOT(any_slot()));

I'm not getting signal in connect() for db

Is there any way to do this?

Whenever any operation on database is done I wanted to execute a function — Vinay Kulkarni, May 17 '15 at 02:33
So why not just call your function directly after `QSqlDatabase::exec` completes? — MrEricSir, May 17 '15 at 03:48
There are many operations at different locations each time I have to call function so I was looking for signal to be connected to function — Vinay Kulkarni, May 17 '15 at 03:50

QSqlDatabase class does not have signals or slots. Qt event loop and the database are not related in anyway. You only perform operations on data and that's it! Subclassing QSqlDatabase and creating custom signals is a bad idea because you wouldn't be able to create and open a connection to the database. So just call your function after db.open() returns true.
