Обсуждение: Arrays in PL/PGSQL

Hello,

Does PL/PGSQL support arrays? Or is their a mechanism to select a set of
records from a table and iterate over all of them.

For example:

DECLARE recs AS RECORDS; //??
BEGIN
SELECT INTO recs * FROM mytable WHERE myfield = 'myvalue';
for i in 1 .. NumRecs loop
    ...
end loop;

Is there a way to do something like this??

    Do it with one record as:

        DECLARE rec record;
        BEGIN
        FOR rec IN SELECT * FROM mytable WHERE myfield = 'myvalue' LOOP
            ...
        END LOOP;

    And BTW, this syntax is documented in the user manual :-)
