在同时插入多个记录时，您可以借助以下语法加快 MySQL 插入速度
START TRANSACTION insert into insertDemo(yourColumnName1,yourColumnName2,...N) values(yourValue1,yourValue2,....N),(yourValue1,yourValue2,....N),.......N commit
让我们首先创建一个演示表
mysql> create table insertDemo -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(20), -> StudentAge int -> ); Query OK, 0 rows affected (0.72 sec)
同时插入多条记录，查询如下 −
mysql> START TRANSACTION;
Query OK, 0 rows affected (0.00 sec)
mysql> insert into insertDemo(StudentName,StudentAge) values('John',21),('Carol',22),('Bob',21),('David',24),
-> ('Maxwell',25),('Mike',22);
Query OK, 6 rows affected (0.00 sec)
Records: 6 Duplicates: 0 Warnings: 0
mysql> commit;
Query OK, 0 rows affected (0.14 sec
使用 select 语句显示表中的所有记录。查询如下 −
mysql> select *from insertDemo;
以下是输出 −
+-----------+-------------+------------+ | StudentId | StudentName | StudentAge | +-----------+-------------+------------+ | 1 | John | 21 | | 2 | Carol | 22 | | 3 | Bob | 21 | | 4 | David | 24 | | 5 | Maxwell | 25 | | 6 | Mike | 22 | +-----------+-------------+------------+ 6 rows in set (0.00 sec)
