Create a file containing the statements below and run it in SQL*Plus
--- file begin ----
set heading of
set feedback off
set pages 1000
set termout off
spool a.sql
select ' Grant Select on '|| table_name || ' to user_name;'
from user_tables ;
spool off
set termout on
set feedback on
set heading on
set pages 14
--- file end ---
To grant a privilige to a user, you have to mention the object and the user.
The select statement creates the right statement to grant the select privilige to the user.
So, you select the objects (table_name from user_tables) and hardcode the user (user_name).
The first three lines instruct SQL to show no heading, no feedback and that 1000 lines will fit on a page
Otherwise the spool file wil contain header rows every couple of rows and the last row in yor spool file
will be something like '50 rows selected.'
Spool file_name instructs SQL to create a file wich contains the output of the statements executed.
The last three lines set everything back to the original state.
The a.sql now contains the grant script for user (user_name).
Just run this a.sql script to grant the select statements to the user.
Another way of granting the select privilige to the user is to type:
grant select on table_name to user_name;
and repeat this for every table_name the grantor owns. If the grantor owns just one or two tables, this might be faster than creating the statements dynamically. If the grantor owns quite a lot of tables, I would use the danamically created statements
