How to Remove Spaces from a String in SQL

To remove spaces from a string in SQL, use the REPLACE function. This function takes three arguments: the string you want to modify, the character you want to replace, and the character you want to replace it with. To remove spaces from a string, you would use the following query:

SELECT REPLACE(string, ' ', '') FROM table_name;

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 remove the spaces from the name column, you would use the following query:

SELECT REPLACE(name, ' ', '') FROM users;

This query would return the result John25Jane30John25Bob20, since all of the spaces have been removed from the name column.

Additional Info

The REPLACE 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. 🤓
