觸發器的建立

今天寫的乙個是我在寫專案時要查詢各個時間段該單據不同的資料。我就想到了做乙個觸發器，當他插入或更新時往另一張表插入資料，拼接查詢。

好了，上**。

這是插入的觸發器

begin

insert
into assets_card_perform (
id,main_id,
depart_id,
depart_code,
depart_name,
assets_type_id,
assets_type_code,
assets_type_name,
assets_ori_value,
acc_deprec,
book_value,
manage_operator,
manage_operator_name,
mon_depre_amount,
spec_type,
storage_place,
use_depart_id,
use_depart_name,
use_operator,
use_operator_name,
use_status,
operator_date
)values
