Re: Referencing Cursor/Row/Record Fields in PL/PgSQL

[Lee Hughes <lee@xxxxxxxxxxxx>]

I thought that's what EXECUTE was for in plpgsql -- isn't there a way to extract the value of a field in a row/record variable by building a SELECT string and passing it to EXECUTE?

There isn't any --- plpgsql doesn't deal in accesses to unknown fields
(mainly because it can't know their type, and it's a strongly typed
language).  Consider plperl or plpython or pl-anything-but-pgsql.
