Thank you for the hint. Unfortunately it still does'nt work. I get ERROR: wrong record constant: »('a'« LINE 2: 5, $${ ('a', 'aa'), ('b', 'bb') }$$ ); ^ DETAIL: Unexpected end of line.

[GENERAL] Insert value input syntax of an array of types without ARRAY/ROW nor casting?
Hi, I'm playing around with array of types but don't get the intuitive syntax really. Given the test snippet below, why do the following insert attempts fail? The literal constant would be the most intuitive syntax. The attempt below also closely follows the documentation AFAIK: http://www.postgresql.org/docs/current/static/arrays.html INSERT INTO mytypetable VALUES ( 5, '{ ('a', 'aa'), ('b', 'bb') }' ); > ERROR: Syntax Error This would be close to Oracle (SQL standard?) syntax by using an implicitly generated constructor with same name as type ('mytypes'): INSERT INTO mytypetable VALUES ( 6, ARRAY[ mytypes('a', 'aa'), ('b', 'bb') ] ); > ERROR: Function mytypes(unknown, unknown) does not exist Any help? Yours, S. -- Testing arrays of types CREATE TYPE mytype AS ( attr1 varchar, attr2 varchar ); CREATE TABLE mytypetable ( id serial, mytypes mytype[10] ); INSERT INTO mytypetable VALUES ( 0, null ); INSERT INTO mytypetable VALUES ( 1, '{ null, null }' ); INSERT INTO mytypetable VALUES ( 2, ARRAY[ (null, null) ]::mytype[] ); INSERT INTO mytypetable VALUES ( 3, ARRAY[ ('a', 'aa'), ('b', 'bb') ]::mytype[] ); INSERT INTO mytypetable VALUES ( 4, ARRAY[ ROW('a', 'aa'), ROW('b', 'bb') ]::mytype[] ); -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
