How to see full query from SHOW PROCESSLIST?

👋 Hey there! Welcome to my tech blog, where I'm all about making complex tech problems feel like a piece of 🍰! Today, we're diving into the world of MySQL queries and tackling the common issue of not being able to see the full query from a SHOW PROCESSLIST command. Let's get started, shall we? 💪

So, you've noticed that when you run SHOW PROCESSLIST, you only see the first 100 characters of the running SQL query in the info column. It's frustrating, especially when you're dealing with queries that are longer than 100 characters. 😫 But fear not, my friend, there are a couple of easy solutions to this problem. Let's take a look at them:

Solution 1: Using the max_allowed_packet Setting

By default, the max_allowed_packet setting in MySQL limits the size of packets sent between the server and clients. This limitation can affect the amount of data returned by SHOW PROCESSLIST, including the query itself. To see the complete query, you can try increasing the max_allowed_packet value in your MySQL configuration.

1. Locate your MySQL configuration file. In many cases, it's named my.cnf or my.ini, depending on your operating system.

2. Open the configuration file in a text editor.

3. Look for the [mysqld] section. If it doesn't exist, you can add it to the file.

4. Add or modify the max_allowed_packet setting. For example, you can set it to 64MB like this: max_allowed_packet=64M.

5. Save the configuration file and restart your MySQL server.

After making these changes, execute the SHOW PROCESSLIST command again, and you should be able to see the complete query in the info column. 🎉

Solution 2: Using the SELECT Statement

If modifying the max_allowed_packet setting doesn't work for you or you don't have access to the MySQL configuration, you can retrieve the complete query by using the SELECT statement instead of SHOW PROCESSLIST.

1. Open your MySQL client or command-line interface.

2. Execute the following query: SELECT * FROM information_schema.processlist.

3. Look for the info column in the result set. Here, you will find the complete query, regardless of its length. 😎

That's it! You now have two easy solutions to see the full query from a SHOW PROCESSLIST command. Choose the one that suits your situation best, and you'll never miss a single character of those lengthy queries again! 💃
