But your complex query isn't in the form where anything will come out
"= 'f'".  You have too many columns in the SELECT.

What you prabably need to do is rewrite it as a subquery in the FROM
clause, alias it as (say) alias_t_inspect, and then use your
condition to get you what you want.   I won't warrant what the
performance will be, however.
