let's say you have the name of a table in a string.
'mytable'
you also have field names, such as
'lookupfield' 'valuefield'
which would be assembled like this
select valuefield from mytable where lookupfield = '?'
is there a way to write sql/plpgsql that'll take a varchar
argument (table and field names) and be able to turn it into the
appropriate query?
i can see pg_class contains table info and pg_attribute has info
for the fields ... is there a way (oids maybe?) to direct
postgres to the right table for a search, given the name of the
table in a varchar string? (and if so, how? :)
