    Then you should rather keep the string of the query and build the QSqlQuery object when you actually need it.

      Can you share the code you are using ?
      It looks like you could make use of a QSqlQueryModel.

          i took a look at QSqlQueryModel but i guess i can't use it because my table view already has a model.

                You can replace your model unless you are doing something special with it ?

                  that's the thing. i can't replace it cause it's doing a lot of things (it's part of a library someone has created and I'm using it)

                    How are you using it since you need to query a database ?

                      it has some long logic built into it, it sets up a lot of connections etc.
