insert_id在Kohana 3

问题描述

我正在将Kohana 3框架与Mysql存储过程一起使用.如何获取最后插入的记录的ID?这是代码:

I'm using Kohana 3 framework with Mysql stored procedures. How can I get id of the last inserted record?Here's the code:

class Model_MyModel extends Kohana_Model
{
    public function insertNew($param1, $param2)
    {
        $result = $this->_db->query(Database::INSERT, 'CALL insertNew('.$param1.', '.$param2.', false)';
        return $result;
    }
    ...
    ...
}

文档说，执行插入查询时，query()方法返回一个带有最后一个插入ID和受影响的行号的数组.当我打电话时:print_r($ result)我越来越:大批( [0] => 0 [1] => 1)尽管我在数据库中有很多记录，但是insert_id键为0.我在做什么错了?

Documentation says, the query() method returns an array with the last insert id and affected rows number, when executing an insert query. When I call: print_r($result)I'm getting:Array( [0] => 0 [1] => 1)The insert_id key is 0, though I'm having many records in the db.What I'm doing wrong?

推荐答案

我认为您在使用过程插入后必须使用SQL的LAST_INSERT_ID():

I think you'll have to use SQL's LAST_INSERT_ID() after inserting using a procedure:

SELECT LAST_INSERT_ID() as last_insert_id FROM table_name

(在您的过程中，只需在最后定义此查询即可).

( in your procedure just define this query in the end ).

在这种情况下，问题在于Kohana会自动返回mysql_insert_id和mysql_affected_rows作为Database :: INSERT的结果，因此您需要以SELECT查询的形式调用该过程并获取它(Database :: SELECT).

The problem in this case is that Kohana automatically returns mysql_insert_id and mysql_affected_rows as result for Database::INSERT, so you'll need to call the procedure as a SELECT query and fetch it (Database::SELECT).
