How to Trim a String in SQL

To trim a single string in SQL, all you have to do is to use the TRIM() function. This function takes two arguments: the string you want to trim and the characters you want to trim from the string. For example, if you wanted to trim the whitespace from the string "  hello  ", you would use the following query:

SELECT TRIM("  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:

‍
If you wanted to trim the whitespace from the name column, you would use the following query:

SELECT TRIM(name) FROM users;

This query would return the result John, Jane, John, and Bob, with no whitespace around the names.

Additional Info

The TRIM() 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. 🤓
