Hi:
v8.3.4 on linux
In plpgsql, I have something like this...
if ((string_to_array(check_values_text,',') <@ string_to_array((select
permitted_values from bi_constraints where bicolumn = 'fivr'),',')) = 'f')
It's just testing all the values in the check_values_text csv are in
permitted_values csv (through array operators as you can see)
I need to do the same thing only for regexp.
So, instead of...
if ((string_to_array('aa,cc,dx',',') <@ string_to_array((select
permitted_values from 'aa,bb,cc,dd,ee' where bicolumn = 'fivr'),',')) = 'f')
(which would flag no compare because "dx" is not in 'aa,bb,cc,dd,ee')
I need to compare with regexp operator...
if ((string_to_array('aa,cc,dx',',') <@ string_to_array((select
permitted_values from 'a.,b.,c*,d*,ee' where bicolumn = 'fivr'),',')) = 'f')
(which would compare OK because "dx" is is matched by "d*")
Don't even know if this sort of thing is possible. I didn't see any operator
like this in the docs. May have to split out each and compare in nested loops
sith atomic regexp compare "~".
Thanks for any ideas and/or help
