Execute set of ddl scripts in pl/sql

Question

Hello,
If I use DBMS_METADATA.GET_DDL and DBMS_METADATA.GET_GRANTED_DDL for a particular user I can get something like this:
CREATE USER "USERB" IDENTIFIED BY VALUES 'B6C9E444D14CDE5B' DEFAULT TABLESPACE "PROD_TBSP_03" TEMPORARY TABLESPACE "TEMP";
GRANT "SELECT_CATALOG_ROLE" TO "USERB";
GRANT "SCHEMA_ROLE" TO "USERB";
Now, how do I go executing this in pl/sql? The following would fail as execute immediate wouldn't run all of these at the same time:
DECLARE
v_str VARCHAR2(4000 BYTE);
BEGIN
v_str := 'CREATE USER "USERB" IDENTIFIED BY VALUES ''B6C9E444D14CDE5B'' DEFAULT TABLESPACE "PROD_TBSP_03" TEMPORARY TABLESPACE "TEMP";'
|| chr(10) || 'GRANT "SELECT_CATALOG_ROLE" TO "USERB";'
|| chr(10) || 'GRANT "SCHEMA_ROLE" TO "USERB";';
dbms_output.put_line(v_str);
EXECUTE IMMEDIATE v_str;
EXCEPTION
WHEN OTHERS
THEN
dbms_output.put_line('Exception encountered: '||SQLCODE||' - Error message: '||substr(SQLERRM,1,200));
END;
Any ideas on how to run it?
Thanks guys
Leo

DECLARE
v_str VARCHAR2(4000 BYTE);
BEGIN
v_str := 'CREATE USER "USERB" IDENTIFIED BY VALUES ''B6C9E444D14CDE5B'' DEFAULT TABLESPACE "PROD_TBSP_03" TEMPORARY TABLESPACE "TEMP";';
dbms_output.put_line(v_str);
EXECUTE IMMEDIATE v_str;
v_str := 'GRANT "SELECT_CATALOG_ROLE" TO "USERB";'
dbms_output.put_line(v_str);
EXECUTE IMMEDIATE v_str;
v_str := 'GRANT "SCHEMA_ROLE" TO "USERB";';
dbms_output.put_line(v_str);
EXECUTE IMMEDIATE v_str;
END;
/You should make sure you really want to do this, though. I don't think this style (ie dynamically running DBA tasks) is a generally accepted "good" practice :)
It's prone to a lot of issues - security and otherwise. Caution is advised.
