When you lied about your SQL skills 🥹⬇️⬇️ 💥 A primary key in SQL is a column (or a set of columns) that uniquely identifies each row in a table. Here are the key points about a primary key: ✅ Uniqueness → No two rows can have the same primary key value. ✅ Not NULL → A primary key column cannot contain NULL values. ✅ Only one per table → Each table can have only one primary key, though it can consist of multiple columns (called a composite primary key). ✅ Enforces entity integrity → Ensures that each record can be uniquely identified. #sql #coding #fyp #wfh #codingmemes #AiAgents #ArtificialIntelligence #SmartTechnology #AIAutomation #FutureOfAI #DigitalAssistants #TechTrends #IntelligentSystems #Innovation #MachineLearning #Robotics #AIFuture #Automation #VirtualAgents #DigitalTransformation #SmartAgents #DataScience #AICollaboration #TechInnovation #airevolution
