How to fasten MySQL inserts?
You can speed the MySQL insert when you are inserting multiple records at the same time with the help of the following syntax
START TRANSACTION insert into insertDemo(yourColumnName1,yourColumnName2,...N) values(yourValue1,yourValue2,....N),(yourValue1,yourValue2,....N),.......N commit
Let us first create a demo table
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)
Insert multiple records at the same time. The query is as follows −
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 secDisplay all records from the table using select statement. The query is as follows −
mysql> select *from insertDemo;
The following is the output
+-----------+-------------+------------+ | 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)
