How to see average game lenght for specific chess opening?

Is there some chess database which allow me to see specific opening game length?

For example:

• Sicilian defense (average length is: 80.5)
• Caro-Kann defense (average length is: 60.7)

I want to learn which opening lead to short, medium, long game.

It is easy to find white/black/draw statistics but hard to find length of games.

Answer 1

Chessbase has a function "Opening Report" which gives average lenght of White wins/Black wins/draws Just setup che base position on the chessboard and right-click it
