Signed data types can store both positive and negative values. For example, an INT data type in SQL can hold values ranging from -2,147,483,648 to 2,147,483,647. This is useful when the data being stored can naturally have negative values, such as in financial calculations or temperature readings. What are unsigned data types? Unsigned data types, on the other hand, can only store non-negative values, effectively doubling the upper limit of the data type's range. For instance, an UNSIGNED INT can hold values from 0 to 4,294,967,295. This is advantageous when you know that negative values will never be part of your data, such as in scenarios involving counts or ages. When should you use signed vs. unsigned? Choosing between signed and unsigned data types depends on the nature of the data you intend to store. If you need to accommodate negative values, opt for signed data types. If your data will always be positive, consider using unsigned data types to maximise the range of possible values. 🔑 Key Features: ✅ Diverse Training Options – Online, Instructor-led, Onsite ✅ Device Compatibility – Access your course on all devices ✅ Interactive Learning Tools - Observe the trainer's screen, utilise virtual whiteboard, and share documents ✅ Best Industry Prize – Obtain your certification at competitive rates ✅ High-Quality Resources - Access detailed resources such as eBooks, Blogs, and more ✅ Worldwide Professional Recognition – Our courses are accredited by globally recognised bodies ✅ Subscribe to our Channel to explore additional top Technologies: https://bit.ly/4f1nM9t About The Knowledge Academy: Global Reach: Join over 2 million successful delegates with The Knowledge Academy High Success Rate: Accomplish your goals with our 98% pass rate Industry Accredited: Learn with confidence, accredited by PeopleCert, PMI Worldwide Centers: Access top-tier learning in 195 countries Excellence Acknowledged: Recognised by The Times and PWC for our commitment Wide Partnerships: Benefit from our extensive network of 3000+ organisations Flexible Learning: Explore diverse training methods tailored to your needs Join us for expert-led courses tailored to your needs, wherever you are.
