What is the fastest way to insert a large number of rows into a MySQL table?
The syntax for the fastest way is given below. Here, we have used INSERT INTO just once and formed an optimized way −
insert into yourTableName values(NULL,yourValue1',yourValue2),(NULL,yourValue1',yourValue2),....N;
Let us first create a table −
mysql> create table DemoTable1839
(
ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
ClientName varchar(20),
ClientAge int
);
Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1839 values(NULL,'Chris',29),(NULL,'Chris',29),(NULL,'Chris',29),(NULL,'Chris',29),(NULL,'Chris',29),(NULL,'Chris',29),(NULL,'Chris',29),(NULL,'Chris',29);
Query OK, 8 rows affected (0.00 sec)
Records: 8 Duplicates: 0 Warnings: 0
Display all records from the table using select statement −
mysql> select * from DemoTable1839;
This will produce the following output −
+----------+------------+-----------+
| ClientId | ClientName | ClientAge |
+----------+------------+-----------+
| 1 | Chris | 29 |
| 2 | Chris | 29 |
| 3 | Chris | 29 |
| 4 | Chris | 29 |
| 5 | Chris | 29 |
| 6 | Chris | 29 |
| 7 | Chris | 29 |
| 8 | Chris | 29 |
+----------+------------+-----------+
8 rows in set (0.00 sec)
