Restoring Orders Table Data from a Text File

Restore Data from a Text File Using LOAD DATA INFILE

Write a MySQL query to restore the "Orders" table data from a previously exported text file.

Solution:

-- This command imports data from a text file into the Orders table
LOAD DATA INFILE '/tmp/Orders_backup.txt'
-- Specifies the target table as Orders for the imported data
INTO TABLE Orders
-- Indicates that fields in the file are separated by commas
FIELDS TERMINATED BY ','
-- Specifies that field values are enclosed in double quotes
ENCLOSED BY '"'
-- Indicates that each record ends with a newline character
LINES TERMINATED BY '\n';

Explanation:

• Purpose of the Query:
