hi all,
below I have created two tables in pgsql with field name as 'name' and 'id'
as their datatype 'varchar(15)' and 'integer'.
One of the table is:->
chemical=> select * from test1;
name | id
-------+----
akhil | 1
b | 2
c | 3
d | 4
e | 5
f | 6
(6 rows)
Another table is:->
chemical=> select * from test3;
name | id
------+----
ab | 1
cd | 2
ef | 3
gh | 4
(4 rows)
i want the output as:->
name | id
-------+----
akhil | 1 -----from test1 table
ab | 1------from test2 table
b | 2-----from test1 table
cd | 2------from test2 table
c | 3-----from test1 table
ef | 3------from test2 table
d | 4-----from test1 table
gh | 4------from test2 table
e | 5-----from test1 table
f | 6-----from test1 table
i have tried all the joins but it makes different fields for different
tables.
is there any way out for this kind of output??????????????????
(plz reply asap)urgent.
THANKS IN ADVANCE

... a UNION of this 2 tables:
test=# select * from test1 union select * from test3 order by 2,1;
name | id
-------+----
ab | 1
akhil | 1
b | 2
cd | 2
c | 3
ef | 3
d | 4
gh | 4
e | 5
f | 6
(10 rows)

<snip>
Looks like:
select * from test1
UNION ALL
select * from test3;
would be a very good start.

given this.....
create table AA (id serial,name varchar(15));
create table BB (id serial,name varchar(15));
insert into AA (name) values ('1243f');
insert into AA (name) values ('asdfef');
insert into AA (name) values ('fdbsfd');
insert into AA (name) values ('btgrt');
insert into AA (name) values ('crregsewf');
insert into AA (name) values ('xedrgeef');
insert into BB (name) values ('243f');
insert into BB (name) values ('sdfef');
insert into BB (name) values ('dbsfd');
insert into BB (name) values ('tgrt');
insert into BB (name) values ('rregsewf');
insert into BB (name) values ('edrgeef');
you could try: (if you just need the one column "name")
select name from AA union select name from BB order by name;
a real nice way to go about this is:
create table CC (id serial,name varchar(15));
create table AA() inherits(CC);
create table BB() inherits(CC);
insert into AA (name) values ('1243f');
insert into AA (name) values ('asdfef');
insert into AA (name) values ('fdbsfd');
insert into AA (name) values ('btgrt');
insert into AA (name) values ('crregsewf');
insert into AA (name) values ('xedrgeef');
insert into BB (name) values ('243f');
insert into BB (name) values ('sdfef');
insert into BB (name) values ('dbsfd');
insert into BB (name) values ('tgrt');
insert into BB (name) values ('rregsewf');
insert into BB (name) values ('edrgeef');
=> select * from AA;
id | name
----+-----------
1 | 1243f
2 | asdfef
3 | fdbsfd
4 | btgrt
5 | crregsewf
6 | xedrgeef
(6 rows)
=> select * from BB;
id | name
----+----------
7 | 243f
8 | sdfef
9 | dbsfd
10 | tgrt
11 | rregsewf
12 | edrgeef
(6 rows)
=> select * from CC order by name;
id | name
----+-----------
1 | 1243f
7 | 243f
2 | asdfef
4 | btgrt
5 | crregsewf
9 | dbsfd
12 | edrgeef
3 | fdbsfd
11 | rregsewf
8 | sdfef
10 | tgrt
6 | xedrgeef
(12 rows)
by best regards,
Stefan
