I have a table that has 7000 rows,
I added a new column to this table
The table has a mysql DateTime so.
一. 更新表格以填入新表格时,该表更新了该日期,
我在进行更新之前就做了一次地板堆放,即现在需要使用地板的垃圾堆回(只有该栏)。
如何这样做?

一. 更新表格以填入新表格时,该表更新了该日期,

如何这样做?
我认为,可以采取两种办法,在我头上这样做。
第一是建立另一个神秘数据库,将垃圾堆放到该数据库(确保它不会从垃圾堆放场中的使用中装入第一个数据库),然后利用该数据库的数据为第一个数据库进行更新查询。
第二,更方便、更贴近的方式是将垃圾堆放到文字编辑中,只从该桌上抽出,找到并替代根据主要钥匙而不是插入对该栏作出更新说明。 你们需要找到并取代模式。
第三种方式是装载S.K.A.K.K.K.L.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.S.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.S.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.A.
第四,如果这种制度不是一种生活体系,那么这种可能性就会退步,重新适应最近的变化(只有简单的话)。
将垃圾堆放到第二位。 选择该表的身份证和日期。 利用这些结果更新原表格中与你所看到的身份证对应的行文。
