Dropping all user tables/sequences in Oracle
- by Ambience
As part of our build process and evolving database, I'm trying to create a script which will remove all of the tables and sequences for a user. I don't want to do recreate the user as this will require more permissions than allowed.
My script creates a procedure to drop the tables/sequences, executes the procedure, and then drops the procedure. I'm executing the file from sqlplus:
drop.sql:
create or replace procedure drop_all_cdi_tables
is
cur integer;
begin
cur:= dbms_sql.OPEN_CURSOR();
for t in (select table_name from user_tables) loop
execute immediate 'drop table ' ||t.table_name|| ' cascade constraints';
end loop;
dbms_sql.close_cursor(cur);
cur:= dbms_sql.OPEN_CURSOR();
for t in (select sequence_name from user_sequences) loop
execute immediate 'drop sequence ' ||t.sequence_name;
end loop;
dbms_sql.close_cursor(cur);
end;
/
execute drop_all_cdi_tables;
/
drop procedure drop_all_cdi_tables;
/
Unfortunately, dropping the procedure causes a problem. There seems to cause a race condition and the procedure is dropped before it executes.
E.g.:

Any ideas on how to get this working?
