如何在MySQL表中插入许多行并返回新的ID? [英] How can I Insert many rows into a MySQL table and return the new IDs?

问题描述

通常，我可以在MySQL表中插入一行并取回last_insert_id.不过，现在，我想将许多行批量插入表中并获取ID数组.有人知道我该怎么做吗?

Normally I can insert a row into a MySQL table and get the last_insert_id back. Now, though, I want to bulk insert many rows into the table and get back an array of IDs. Does anyone know how I can do this?

有一些类似的问题，但它们并不完全相同.我不想将新ID插入任何临时表；我只想找回ID数组.

There are some similar questions, but they are not exactly the same. I don't want to insert the new ID to any temporary table; I just want to get back the array of IDs.

可以从批量插入物中检索lastInsertId吗?

带有last_insert_id的MySQL多行插入选择语句()

推荐答案

旧线程，但只是调查了一下，所以去了:如果您在最新版本的MySQL上使用InnoDB，则可以使用LAST_INSERT_ID()和ROW_COUNT().

Old thread but just looked into this, so here goes: if you are using InnoDB on a recent version of MySQL, you can get the list of IDs using LAST_INSERT_ID() and ROW_COUNT().

如果innodb_autoinc_lock_mode设置为0(传统)或1(连续)，InnoDB保证批量插入时AUTO INCREMENT的序列号. 因此，通过添加ROW_COUNT()-1，您可以从LAST_INSERT_ID()获得第一个 ID，并从最后获得.

InnoDB guarantees sequential numbers for AUTO INCREMENT when doing bulk inserts, provided innodb_autoinc_lock_mode is set to 0 (traditional) or 1 (consecutive). Consequently you can get the first ID from LAST_INSERT_ID() and the last by adding ROW_COUNT()-1.
