我们如何使用 mysqlimport 将数据上传到多个 MySQL 表？

借助 mysqlimport，我们可以将数据上传到多个 MySQL 表。下例对此进行了说明——

例如

假设我们希望从两个数据文件 student1_tbl.txt——

1     Saurav     11th
2     Sahil      11th
3     Digvijay   11th

和 House.txt 中上传以下数据

1   Furniture
2   Television
3   Refrigerator

下面是我们希望向其中上传以上数据的 MySQL 表——

mysql> DESCRIBE Student1_tbl;
+--------+-------------+------+-----+---------+-------+
| Field  | Type        | Null | Key | Default | Extra |
+--------+-------------+------+-----+---------+-------+
| RollNo | int(11)     | YES  |     | NULL    |       |
| Name   | varchar(20) | YES  |     | NULL    |       |
| Class  | varchar(20) | YES  |     | NULL    |       |
+--------+-------------+------+-----+---------+-------+
3 rows in set (0.06 sec)

mysql> DESCRIBE House;
+-------+-------------+------+-----+---------+-------+
| Field | Type        | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+-------+
| Sr    | int(11)     | YES  |     | NULL    |       |
| Name  | varchar(20) | YES  |     | NULL    |       |
+-------+-------------+------+-----+---------+-------+
2 rows in set (0.00 sec)

现在，借助以下命令，我们能够将数据上传到这两个表中——

C:\mysql\bin>mysqlimport -u root query C:/mysql/bin/mysql-files/student_tbl.txt C:/mysql/bin/mysql-files/house.txt
query.student_tbl: Records: 3 Deleted: 0 Skipped: 0 Warnings: 0
query.house: Records: 3 Deleted: 0 Skipped: 0 Warnings: 0

mysql> Select * from House;
+------+--------------+
| Sr   | Name         |
+------+--------------+
| 1    | Furniture    |
| 2    | Televisoin   |
| 3    | Refrigerator |
+------+--------------+
3 rows in set (0.00 sec)

mysql> Select * from student1_tbl;
+--------+----------+-------+
| RollNo | Name     | Class |
+--------+----------+-------+
| 1      | Saurav   | 11th |
| 2      | Sahil    | 11th |
| 3      | Digvijay | 11th |
+--------+----------+-------+
3 rows in set (0.00 sec)
