Exporting Orders Table Data for Backup

Backup a Table to a Text File Using SELECT ... INTO OUTFILE

Write a MySQL query to back up the "Orders" table data into a text file.

Solution:

-- This command exports all data from the Orders table to a CSV file
SELECT * FROM Orders
-- Specifies the output file location and name as /tmp/Orders_backup.txt
INTO OUTFILE '/tmp/Orders_backup.txt'
-- Sets the field separator to a comma for CSV formatting
FIELDS TERMINATED BY ','
-- Encloses field values in double quotes to handle special characters
ENCLOSED BY '"'
-- Sets the line separator to a newline character for row separation
LINES TERMINATED BY '\n';

Explanation:

• Purpose of the Query:
• To create a backup of table data in a text format for easy recovery or analysis.
