PostgresSQL: Get single attribute of UDT in SELECT statement
-

Question
I created a user-defined type in a PostgreSQL 9.2 database and am trying in the SELECT
statement to get only an attribute of the UDT. However, I don't seem to get my code to work.
Creation of type and table:
CREATE TYPE ttp AS (f1 int, f2 int);
CREATE TABLE tbl (ctyp ttp);
The SELECT
statement:
-- does not work
SELECT ctyp.f1 FROM tbl
SELECT ctyp(f1) FROM testtable
Both times I get an error. Is it possible to access a single attribute defined in a UDT in a SELECT
?
No correct solution
