我找到了运行mysql查询以将一个表迁移/拆分为2个新表的一些选项，但我想在新表上创建的一个字段必须与另一个新表中的字段相同：< / p>
所以从“From_payments”表中，我想创建两个名为“To_paymenttransaction”和“To_paymentinfo”的新表。该字段的lof是预定义的，一些来自旧表。唯一的问题是预定义字段“paymentinfoid”必须与新表相同。
**To_paymenttransaction** --- < --- **From_payments**
paymenttransactionid ------- < --- (Generate next available number in this column)
paymentinfoid -------------- < --- (Generate next available number in this column)
transactionid --------------- < --- txn_id
state ---------------------- < --- (Set all to "1")
amount -------------------- < --- mc_gross
currency ------------------- < --- mc_currency
dateline -------------------- < --- payment_date
paymentapiid --------------- < --- (Set all to "1")
request -------------------- < --- (Set all to "NULL")
reversed ------------------- < --- (Set all to "0")
**To_paymentinfo** -----------<
paymentinfoid -------------- < --- (Same generated number that goes to the paymentinfoif field in To_paymenttransaction table )
hash ----------------------- < --- (Set all to "Imported")
subscriptionid --------------- < --- (Set all to "1")
subscriptionsubid ------------ < --- ("2" IF above field mc_gross is 4, "1" IF above field mc_gross is 6, "0" IF above field mc_gross is 10)
userid ---------------------- < --- userid
completed ------------------ < --- (Set all to "0")
有什么想法吗？
非常感谢所有帮助。

在分割之前，可能会在原始表上生成paymentinfoid。然后，您可以将该单个条目复制到每个新表中。
