AirOps | SQL Guide • How to Check the Length of a String in SQL (free SQL tool) (2024)

Are you trying to figure out the length of a string in SQL? It's easy! With the LENGTH() function, you can quickly and easily get the length of a string in SQL.

The Solution

The solution is to use the LENGTH() function. This function takes a single argument, which is the string you want to get the length of. For example, if you wanted to get the length of the string 'Hello World', you would use the following query:

SELECT LENGTH('Hello World');

This query would return the result 11, since the string 'Hello World' has 11 characters.

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:

If you wanted to get the length of the name column, you would use the following query:

SELECT LENGTH(name) FROM users;

This query would return the results 4, 4, 4, and 3, since the names John, Jane, and Bob have 4 characters each, and John appears twice.

Additional Info

The LENGTH() 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. 🤓
