How to Convert a String to Uppercase in SQL

How to Convert a String to Uppercase in SQL

Are you looking for a way to convert a string to uppercase in SQL? You're in luck! SQL provides a handy function for converting strings to uppercase, which can be used to quickly and easily convert strings to uppercase.

The Solution

The solution is to use the UPPER() function. This function takes a single argument, which is the string you want to convert to uppercase. For example, if you wanted to convert the string hello to uppercase, you would use the following query:

SELECT UPPER('hello');

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 the name column to uppercase, you would use the following query:

SELECT UPPER(name) FROM users;

This query would return the result JOHN, JANE, JOHN, BOB, since all of the names in the table have been converted to uppercase.

Additional Info

The UPPER() 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. 🤓
