Quick Answer

Handle restricted operations.

Understanding the Issue

Some SQL commands are disabled or restricted based on server configuration or security settings.

The Problem

This code demonstrates the issue:

Sql Error 
SELECT * INTO OUTFILE '/tmp/data.csv' FROM users; -- Error if disabled

The Solution

Here's the corrected code:

Sql Fixed 
-- Solution 1: Use alternative commands
-- Instead of INTO OUTFILE, use client-side export

-- Solution 2: Check secure_file_priv
SHOW VARIABLES LIKE 'secure_file_priv';

-- Solution 3: Grant necessary privileges
GRANT FILE ON *.* TO 'user'@'host';

-- Solution 4: Modify server configuration
-- Edit my.cnf/my.ini and restart server

-- Solution 5: Use database-specific alternatives
-- MySQL: mysqldump instead of SELECT INTO
