create or replace trigger D_m_account_data for delete on M_ACCOUNT_DATA compound trigger // Declaration // Body before statement is begin NULL; end before statement; before each row is begin NULL; end before each row; after each row is begin NULL; end after each row; after statement is begin NULL; end after statement; END / create or replace trigger I_m_account_data for insert on M_ACCOUNT_DATA compound trigger // Declaration // Body before statement is begin NULL; end before statement; before each row is begin NULL; end before each row; after each row is begin NULL; end after each row; after statement is begin NULL; end after statement; END / create or replace trigger U_m_account_data for update on M_ACCOUNT_DATA compound trigger // Declaration // Body before statement is begin NULL; end before statement; before each row is begin NULL; end before each row; after each row is begin NULL; end after each row; after statement is begin NULL; end after statement; END / 这个是出异常的sql代码
