This article mainly introduces the mysql batch data entry method, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to know about it.

Mysql batch input data methods: 1, the use of circular insertion; 2, reduce connection resources, splice a sql;3, use stored procedures; 4, use [MYSQL LOCAL_INFILE].

The method of batch inputting data in mysql:

Method 1: circular insertion

This is also the most common way, if the amount of data is not very large, you can use it, but you have to consume the resources to connect to the database every time.

The general thinking is as follows

(I write pseudo code here, which can be written in combination with my own business logic or framework syntax.)

For ($itim1bot / value) {$sql = 'insert.'; / / querysql} while ($I exec ($sql); if (! $res) {/ / TODO insert failure} @ unlink ($my_file);}}

Again, each piece of data is very large, with a lot of varchar4000 and text fields.

It takes 2.160s

The above meet the basic needs, 1 million data is not a big problem, or the data is too large also involves sub-database sub-table, or the use of queue insertion.

Thank you for reading this article carefully. I hope the article "mysql bulk data entry method" shared by the editor will be helpful to everyone.
