1、
select 'Drop table '||table_name||';' 2、 删除所有表
for example:
declare 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
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;
