How to Concatenate Strings in SQL

Do you need to combine two or more strings together in your SQL database? Concatenating strings is a common task in SQL, and it's easy to do with the CONCAT() function. This function takes two or more strings as arguments and returns a single string that is the combination of all the arguments. Let's take a look at how it works!

The Solution

The CONCAT() function takes two or more strings as arguments and returns a single string that is the combination of all the arguments. For example, if you wanted to combine the strings 'Hello' and 'World', you would use the following query:

SELECT CONCAT('Hello', 'World') FROM table_name;

This query would return the result 'HelloWorld'.

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 combine the name and age columns into a single string, you would use the following query:

SELECT CONCAT(name, age) FROM users;

This query would return the result 'John25Jane30John25Bob20'.

Additional Info

The CONCAT() 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. 🤓
