我可以获取最后插入行的列吗？

Question

Hi I'm using Codeigniter and would love a solution in CI but can suffice with mysqli or PDO.

I was wondering if there is a way to get a column of the last inserted row in MySql 5.1.54

The reason is I'm inserting a null value which then a trigger changes that null into some calculated value and instead of getting the last inserted id and querying for that value.

Is there some way this can be done?

In case I wasn't clear : I know I can run a query on last inserted id, I mean can I get last inserted "column"?

Answer 1

You can get the last inserted id by

$this->db->insert_id();

and select the last row and use it normally

ref Query Helper

Answer 2

The PDO comes with lastInsertId method . You can then SELECT * FROM table WHERE id=return_of_this_function .

Answer 3

我猜猜@Eric正在寻找的答案是否定的。
