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)
