I want to have an array of composite type in a table. Retrieving/saving value work fine.
I just wonder how I can search against composite type array.
CREATE TYPE CompXYZ AS (
attr1 integer,
attr2 text,
attr3 inet
);
CREATE TABLE sample (
id integer not null primary key,
list CompXYZ[]
);
insert into sample values (1, '{"(1,abc,127.0.0.1)", "(5,def,10.0.1.2)"}');
insert into sample values (2, '{"(10,hello,127.0.0.1)", "(20,def,10.0.1.2)"}');
insert into sample values (3, '{"(20,hello,10.1.1.1)", "(30,there,10.1.1.2)"}');
How I can search a row containing "hello" for attr2?
I know if I have a separate table for saving 3 attributes along with foreign key to sample table, then I can achieve my goal.
I just want to know if there is a way to do the same thing using composite array.
Thank you,
