How to Change Text to Lowercase in SQL
Have you ever wanted to change the case of text in your database? Whether you want to make all the text lowercase or uppercase, SQL has a handy way of doing it.
The Solution
The solution is to use the LOWER() function. This function takes a single argument, which is the text you want to convert to lowercase. For example, if you wanted to convert the text Hello World to lowercase, you would use the following query:
SELECT LOWER('Hello World');This query would return the result hello world.
Examples
Let's look at a few examples of how this function can be used. Suppose you have a table called users with the following data:
name age
----------------
John 25
Jane 30
John 25
Bob 20
If you wanted to convert all the names to lowercase, you would use the following query:
SELECT LOWER(name) FROM users;This query would return the results john, jane, john, and bob.
Additional Info
The LOWER() function is supported by most major databases, including MySQL, PostgreSQL, and SQL Server. However, the syntax may vary slightly depending on the database you are using. For more information, check out the documentation for your particular database. 🤓
