Consider this function:
CREATE OR REPLACE FUNCTION php_get_subfield_data_repeating(int4,
"varchar") RETURNS SETOF "varchar" AS
$BODY$
DECLAREaRecordID ALIAS FOR $1;aSubFieldId ALIAS FOR $2;
returnValue record;subFieldNumber char(3);subFieldLetter char(1);
BEGINsubFieldNumber = substr(aSubFieldId, 1, 3);subFieldLetter = substr(aSubFieldId, 4);
FOR returnValue IN SELECT "subfieldValue"::varchar FROM "records_sub" WHERE "fieldTag" =
subFieldNumberAND "subfieldTag" = subFieldLetter
AND "recordId" = aRecordIdLOOP RETURN NEXT returnValue;END LOOP;
RETURN;
END
$BODY$ LANGUAGE 'plpgsql' VOLATILE;
Now, when I do this:
biblio3=# select * from php_get_subfield_data_repeating(1,'606a');php_get_subfield_data_repeating1
----------------------------------(Anđeli)(ofsajd)
(2 rows)
I have return values in parentheses. However, if I create a new type:
CREATE TYPE subfield_data_type AS (subfield_data varchar);
And then drop the function and recreate it like this:
CREATE OR REPLACE FUNCTION php_get_subfield_data_repeating(int4,
"varchar") RETURNS SETOF subfield_data_type AS
$BODY$
...
And then when I run the function, the results are ok:
biblio3=# select * from php_get_subfield_data_repeating(1,'606a');subfield_data
---------------Anđeliofsajd
(2 rows)
Am I doing something wrong here? Why do I need to create type with only
one member of type varchar to have results without the parentheses?
Mike
P.S. The subFieldValue field in the records_sub table is of type
varchar(4096).
