oracle删除某个用户所有表

1、select 'Drop table '||table_name||';' from all_tables where owner='要删除的用户名（注意要大写）'; 2、删除所有表以用户test为例for example:declarecursor 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、这个删除当前用户的所有对象(表、视图、触发器、存储过程、函数) 没试过DECLARETYPE 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);BEGINsql_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 LOOPsql_str := 'DROP ' || Tab_type(i) || ' ' || Tab_name(i);EXECUTE IMMEDIATE sql_str;END LOOP;END;
