Example of Resolving MySQL Error 2013 Lost Connection
Example 1: SQL Schema with Long-Running Query
-- Schema
CREATE TABLE large_table (
id INT PRIMARY KEY,
data VARCHAR(255)
);
-- Inserting sample data
INSERT INTO large_table (id, data)
VALUES
(1, 'Lorem ipsum dolor sit amet'),
(2, 'Consectetur adipiscing elit'),
-- ... add more sample data ...
-- Long-running query
SELECT * FROM large_table WHERE LENGTH(data) > 1000;
Output:
In this example, we create a table named large_table with some sample data. The long-running query is designed to fetch rows where the length of the data column is greater than 1000 characters, simulating a resource–intensive operation.
Example 2: SQL Schema with Network Disruption:
-- Schema
CREATE TABLE sensitive_data (
user_id INT PRIMARY KEY,
username VARCHAR(50),
password VARCHAR(50)
);
-- Inserting sample data
INSERT INTO sensitive_data (user_id, username, password)
VALUES
(1, 'john_doe', MD5('password123')),
(2, 'jane_smith', MD5('securepass')),
-- ... add more sample data ...
-- Data-intensive operation
UPDATE sensitive_data SET password = MD5(CONCAT(username, NOW()));
Ouput:
In this example, we create a table named sensitive_data with some sample data. The data-intensive operation involves updating the password column with a hashed value based on the username and the current timestamp, simulating an operation that may cause network disruptions.a
