the procedure must be owned by the same schema that owns the table

then you can simply do something like this...

create or replace trunc_table(p_tablename in varchar2)
is
begin
execute immediate 'truncate table ' || p_tablename;
end;

then grant execute on the procedure to your other schema

to add protection against sql injection it would be good to check the parameter to confirm it is the name of a table.  You could wrap it in double quotes within the execute immediate call too.


execute immediate 'truncate table "' || p_tablename || '"';

If you already have been given explicit permission to truncate the other schema's table,  just add the schema to the truncate command:

execute immediate 'truncate table schema.table';

>>> If you already have been given explicit permission to truncate the other schema's table

there is no "truncate table" permission that can be granted

the closest you can get is "drop any table"  which is NOT recommended


also,  small mistake above,  I left out the key word "PROCEDURE"


create or replace procedure trunc_table(p_tablename in varchar2)
is
begin
execute immediate 'truncate table ' || p_tablename;
end;

Wasn't implying a 'truncate table' permission.  Just stating that if they already had permission to issue a truncate command...
