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)
