This exciting release of Boolean Data Type Lab for Oracle Database 23c AI introduces native support for the boolean data type, a game-changer for database developers. With this enhancement, you can natively represent true, false, and null values, simplifying data modeling and making SQL and PL/SQL development more efficient.

To illustrate, let's recreate a scenario involving a Student Information System, where we'll track whether students are currently enrolled in courses using the new boolean data type.

Now let's populate the table with sample data using different boolean literals:

To retrieve students who are currently enrolled:

Boolean values allow for direct logical operations. For example, filtering students considered "actively enrolled":

To identify students who are not currently enrolled:

Let's retrieve students who are either enrolled or whose names start with 'A':

Suppose we want to update Bob's enrollment status:

PL/SQL seamlessly integrates with the new boolean data type. Let's add a new student:

The introduction of the boolean data type in Oracle Database 23c AI simplifies database design and improves the readability and maintainability of your SQL and PL/SQL code. Reducing reliance on workarounds like numeric or character codes empowers developers to write cleaner and more intuitive queries.

Whether managing a Student Information System or any other application, the boolean data type makes handling logical values straightforward and robust. Get hands-on experience today, and see how this feature can elevate your database projects.
