Thread: Group by clause - Postgres 9.2.4
I need some help
I was given the SQL called as insert into usr_role (select usr_id, '501~734' from usr_role where role_id = '501~703' group by usr_id); to be run in a server which will work fine but I need to construct another one to work the same way for the master table called corp_usr_role. Given the following 2 tables, is it correct to have the SQL as insert into corp_usr_role (select usr_id,ctry_cde,grp_cde, '501~734' from corp_usr_role where role_id = '501~703' group by usr_id,ctry_cde,grp_cde,role_id);
First table :
Table "public.corp_usr_role"
Column | Type | Modifiers
----------+------+-----------
ctry_cde | text | not null
grp_cde | text | not null
usr_id | text | not null
role_id | text | not null
Indexes:
"pk_cur" PRIMARY KEY, btree (ctry_cde, grp_cde, usr_id, role_id)
2nd table :
Table "public.usr_role"
Column | Type | Modifiers
---------+------+-----------
usr_id | text |
role_id | text |
Indexes:
"idx_usr_role_role" btree (role_id)
"idx_usr_role_usr" btree (usr_id)

As for your question it seems like something you can easily resolve on your own since you supposedly have data and a way to run queries. If your run the above query against your data do you get the results you expect? I do question whether having a constant in the select-list is something you really want but since you provide no context and no data... David J. P.s. Decided to read more closely...you seem to want to add a new role to all existing users with a given role. Whether this makes sense depends on the data. Regardless, your corporate query does not do what you want. -- View this message in context: http://postgresql.nabble.com/Group-by-clause-Postgres-9-2-4-tp5829741p5829763.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com.
