How to Convert an Integer to a Decimal in SQL

Are you looking for a way to convert an integer to a decimal in SQL? You've come to the right place! Converting an integer to a decimal in SQL is a simple process that can be done with a few lines of code. Read on to learn how it's done. 🤓

The Solution

The solution is to use the CAST function. This function takes two arguments: the value you want to convert, and the type you want to convert it to. For example, if you wanted to convert an integer to a decimal, you would use the following query:

SELECT CAST(integer_column AS DECIMAL) 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 convert the age column to a decimal, you would use the following query:

SELECT CAST(age AS DECIMAL) FROM users;

This query would return the result 25.0, 30.0, 25.0, 20.0, since the age column is now a decimal.

Additional Info

The CAST 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. 🤓
