How can we export certain fields from a MySQL table into a text file?
This can be done by providing the column names in the SELECT … INTO OUTFILE statement when exporting data from a MySQL table to a file. We illustrate with the help of the following example-
Example
Suppose we get the following data from the table "Student_info"-
mysql> Select * from Student_info; +------+---------+------------+------------+ | id | Name | Address | Subject | +------+---------+------------+------------+ | 101 | YashPal | Amritsar | History | | 105 | Gaurav | Chandigarh | Literature | | 125 | Raman | Shimla | Computers | | 130 | Ram | Jhansi | Computers | | 132 | Shyam | Chandigarh | Economics | | 133 | Mohan | Delhi | Computers | +------+---------+------------+------------+ 6 rows in set (0.07 sec)
Suppose we only want to get the "id" from the above table " and "Name" columns are exported to the file, then the following query can export only the "id" and "name" values in the "Student_info" table to a file named "student1.txt"-
mysql> Select id, Name from Student_info INTO OUTFILE 'C:/mysql/bin/mysql-files/student1.txt'; Query OK, 6 rows affected (0.07 sec)
The above query will create a file named "Student.txt" and export the values of the "id" and "name" columns in the "Student_info" table to the file.
