如何截断oracle中的所有用户表？我有表约束的问题.
declare
begin
for c1 in (select table_name,constraint_name from user_constraints) loop
begin
execute immediate ('alter table '||c1.table_name||' disable constraint '||c1.constraint_name);
end;
end loop;
for t1 in (select table_name from user_tables) loop
begin
execute immediate ('truncate table '||t1.table_name);
end;
end loop;
for c2 in (select table_name,constraint_name from user_constraints) loop
begin
execute immediate ('alter table '||c2.table_name||' enable constraint '||c2.constraint_name);
end;
end loop;
end;
