Help with truncating a table using plsql procedure in different schema

Question

I have a plsql procedure in schema A that truncates a table that is given in as parameter.
create or replace procedure truncate_table(schema, table_name)
EXECUTE IMMEDIATE 'TRUNCATE TABLE '||schema||'.'||table_name;
end;
The above procedure has public execute grant.
I need to truncate a table in schema B. I have a plsql procedure in schema B that calls the truncate_table procedure and passes in the schema B table name.
Since the table is in schema B, should the delete grant on the table be given to user A or user B to truncate the table in schema B?
Thanks in advance.

Answer 1

Procedure created in schema A
create or replace
procedure truncate_table(l_schema varchar2, table_name varchar2) authid current_user
as
begin
EXECUTE IMMEDIATE 'TRUNCATE TABLE '||l_schema||'.'||table_name;
end;from schema B
grant delete on table1 to Schema_A
from schema A
exec truncate_table('Schema_B','Table1');
Hope this helps.
