我有一个表(T1),有些领域F2、F3(哥伦斯)已经有一些价值。
I need to add a new field (F1) to the table (T1) and F1 will be the primary key .
F1的实地类型是ger。
我将随机的8位数分配给第一行的F1,其余各行应从前行中加1。 这种增益应与其他领域F2、F3等相同。
如果在表格中增加全新行,也应增加这一F1。
我试图用购买力平价中的最后产品来做,但只为新创建的浏览器工作。
Can u ppl help me in writing the code for the above using lastinsertid().
If its not clear plzz let me know..
If you are using MySQL:
ALTER TABLE myTable
AUTO_INCREMENT = 1677216 ,
ADD COLUMN F1 INT PRIMARY KEY AUTO_INCREMENT ;
现有各行将有<条码>F1,自<条码>16772<16/代码>起,自动填满。
如果有人担心这是一种愤怒,而不是一种扼杀,则预示着它永远不会使用<条码>id<>代码/代码>,但只使用<条码>。
