Folks,

This is driving me crazy...I'm sure it's possible but that I am getting the
#quotes wrong in some way...
I keep getting unterminated string errors...now matter how many quotes I
use.

I have a FN that I want to loop through all views and populate a table with
a count(*) from each views.

To do it I'm doing a LOOP around all views...something like:

FOR r_rec IN SELECT viewname from pg_views
LOOP

    sql_string := 'INSERT INTO temp_table ( view_name, row_count ) SELECT
''' || r_rec.viewname || ''', count(*) FROM ' || r_rec.viewname  || ' ; ' ;

    EXEC sql_string ;

END LOOP ;

END ;


Building that sql_string is the problem.
Any thoughts folks?
