[Qgis-developer] Add a WHERE clause to field calculator

[Neumann, Andreas]

Hi, 

Would it be possible to add a "WHERE" clause to the field calculator?
Currently, if you want to update a subset of the records you would have
to do a two-step producedure: 

1. Make a selection 

2. Open field calculator and use the checkbox "only update selected
features". 

I think, in some workflows it would be more efficient if one had a text
input area where one can enter a WHERE clause and the field calculator
would respect the WHERE clause, if filled in. It would reduce the
two-step operation into a one or 1.5 step operation, so more efficient.
If you have to update based on multiple different subsets it would be
even more efficient. 

Would this be a useful enhancement to more users? Esp. for those who
know SQL ;-) ? 

Thanks and greetings, 

Andreas
