Subject: [SQL] returning values to variables from dynamic SQL
I have a PG function ( using plpgsql) that calls a number of sub functions
also in plpgsql. I have two main problems that seem to be variations on the
same theme of running dynamic SQL from a variable with the EXECUTE statement
and returning the results back to a variable defined in the calling
function.

Basically when you use "EXECUTE" you do not embed the "INTO" as part of the
SQL query but rather INTO becomes a modifier of the EXECUTE itself:
EXECUTE 'some query' INTO {variables}
