How can I search (case-insensitive) in a column using LIKE wildcard?

🌳 The Wild Search: Case-Insensitive LIKE in SQL 🌳

Searching for specific data in a database is like finding a needle in a haystack 🧵🆚. But what if we told you that there's a way to search for data regardless of its casing, making the search process smoother and more efficient? 🤔

👀 The Case of the Elusive Elm 👀

Let's dive into a common scenario: you have a table called trees with a column named title, and you want to search for all trees that contain the word "elm". Easy peasy, right? 🌳

SELECT * FROM trees WHERE trees.`title` LIKE '%elm%'

This query seems to do the trick, until you stumble upon a tree named "Elm" or "ELM". Uh-oh! The case sensitivity of the SQL LIKE wildcard search strikes again! 😬

🎭 Making SQL Dance to Your Beat 🕺

Lucky for you, there's a simple solution to your case-insensitive woes. The magic lies in using the right combination of SQL functions and operators. In this case, we'll use the LOWER() function and the LIKE operator together:

SELECT * FROM trees WHERE LOWER(trees.`title`) LIKE '%elm%'

By converting the title column to lowercase using the LOWER() function and then performing the wildcard search with the LIKE operator, we ensure a case-insensitive search. Now those elusive "Elm" and "ELM" trees won't escape your sight! 👀✨

🚀 Level Up Your SQL Game 🎮

But wait, there's more! 💫 Here are a few additional tips to level up your SQL query game:

1. If you're dealing with a large dataset, consider adding an index to the title column. This can significantly improve search performance.

2. Want to search for variations of a word? Use the % wildcard before and after the search term. For example, searching for '%elm%' will match "elm", "elms", "elmwood", and so on.

3. Keep in mind that the specific syntax for case-insensitive searches can vary depending on the database management system you're using. The LOWER() function is commonly supported, but do check the documentation of your specific database for any syntax nuances.
