Thread: update ARRAY of COMPOSITE TYPE of text
I did: CREATE TYPE telephone AS ( area text, number text, ext text ); Then: CREATE TABLE directory ( id integer, tel telephone, faxes telephone[] ); After some data has been entered, I tried: UPDATE directory SET tel = ROW('11', '2222222', '333') WHERE id = 1; UPDATE directory SET faxes[1] = ROW('11', '2222222', '333') WHERE id = 1; both worked fine, but: UPDATE directory SET faxes = ARRAY[ROW('11', '2222222', '333'), ROW('44', '555', '666')] WHERE id = 1; has failed: (You will need to rewrite or cast the expression) with arrow pointing to ARRAY. Does anybody know how to overcome it? Please note, I'm not seeking an alternative, as I can still do the following: UPDATE directory SET faxes = '{(11\,2222222\,333),(44\,555\,666)}' WHERE id=1; I would like, however, do the same with ARRAY/ROW.

Just like it says, cast the expression: UPDATE directory SET faxes = ARRAY[ROW('11', '2222222', '333'), ROW('44', '555', '666')]::telephone[] WHERE id = 1; or if it's more convenient for your app, do it like this: UPDATE directory SET faxes = ARRAY[ROW('11', '2222222', '333')::telephone, ROW('44', '555', '666')::telephone] WHERE id =1; I don't recall at the moment why we allow implicit casting from an anonymous "record" type to a named composite type but not from record[] to an array of named composite. There might be a good reason for it, or just a lack of round tuits. regards, tom lane
