The statement not valid SQL for WWSF without prefop allins

[sky44]

I am trying to create columns for WWSF, but I get an error

What's wrong with this?

sum(if[ tourney_hand_player_statistics.flg_f_saw
AND lookup_actions_f.action LIKE '_%'
AND tourney_hand_player_statistics.flg_won, 1, 0 ])

I tried writing it differently

sum(if[ flg_f_saw AND lookup_actions_f.action LIKE '_%' AND flg_won, 1, 0 ])

But it's still an error.

The default cnt_f_saw_won column contains tourney_hand_player_statistics.flg_won_hand and you are using tourney_hand_player_statistics.flg_won which does not exist in the database schema.
