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)    CONFIDENTIALITY NOTICE The contents of and attachments to this e-mail are intended for the addressee only, and may contain the confidential information of Argility (Proprietary) Limited and/or its subsidiaries.
