1、
select 'Drop table '||table_name||';'
from all_tables
where owner='要刪除的使用者名稱(注意要大寫)';
2、
刪除所有表
以使用者test為例
for example:
declare
cursor cur1 is select table_name from dba_tables where owner='TEST';
begin
for cur2 in cur1 loop
execute immediate 'drop table test.'||cur2.table_name;
end loop;
end;
3、這個刪除目前使用者的所有對象(表、視圖、觸發器、預存程序、函數)
沒試過
DECLARE
TYPE name_list IS TABLE OF VARCHAR2(40);
TYPE type_list IS TABLE OF VARCHAR2(20);
Tab_name name_list:=name_list();
Tab_type type_list:=type_list();
sql_str VARCHAR2(500);
BEGIN
sql_str := 'select uo.object_name,uo.object_type from user_objects uo where uo.object_type not in(''INDEX'',''LOB'') order by uo.object_type desc';
EXECUTE IMMEDIATE sql_str BULK COLLECT INTO tab_name,tab_type;
FOR i IN Tab_name.FIRST.. Tab_name.LAST LOOP
sql_str := 'DROP ' || Tab_type(i) || ' ' || Tab_name(i);
EXECUTE IMMEDIATE sql_str;
END LOOP;
END;
