SQL: delete all the data from all available tables

Question

I am using oracle DB to maintain more than 30 tables, how can I delete all the data from all the tables? I only want to delete the data but not drop the tables.

Answer 1

Delete all the data from all tables in oracle

DECLARE
  str VARCHAR2(100);
BEGIN
  FOR i IN
  (SELECT object_name FROM user_objects WHERE object_type='TABLE'
  )
  LOOP
    str := 'Truncate table '|| i.object_name;
    EXECUTE IMMEDIATE str;
    DBMS_OUTPUT.PUT_LINE('table data deleted :' || i.object_name);
  END LOOP;
END;
