hi, now i meet a question about the complex field. Firstly i create a complex
type (the sql is "CREATE TYPE test11 as (area numeric, address character
varying(30))")and then i create a table ,set a field named "tt" whose type is
test11. Now i want insert the data which select from another talble
yantian_2005 into the tt of test1. but i try some SQL and always failure. so i
wish you can tell me how to do .The following is my sql and their error.
(1)select (eid,address,area1,marea,shape_area,shape_len,the_geom,gid)into
table1 from yantian_2005 where gid=2
ERROR: column "row" has pseudo-type record
(2)insert into test1(tt)select row(yantian_2005.address, yantian_2005.area1
)from yantian_2005 where gid=3;
ERROR: cannot cast type record to test11
(3)select Row (yantian_2005.address,yantian_2005.area1)::{tt} into table1 from
yantian_2005 where gid=2
ERROR: syntax error at or near "{"
LINE 1: ...ct Row (yantian_2005.address,yantian_2005.area1)::{tt} into ...
please tell me how to do.
my postgresql is 8.2 and system is windows XP.
