SQL INSERT | UPDATE | DELETE

https://github.com/SMSiddhesh/SQL/blob/main/Insert%20Update%20Delete
This text outlines the fundamental SQL commands used to manage information within a database, specifically focusing on CRUD operations. The INSERT command allows users to populate tables by adding new records, either for every column or specific fields. To modify existing entries, the UPDATE statement is employed, though the author highlights the critical necessity of using a WHERE clause to avoid unintentionally changing every row. Similarly, the DELETE function removes data, with a clear warning regarding its permanent nature compared to the faster TRUNCATE method. Throughout the guide, practical banking examples and safety tips, such as verifying data with a SELECT query first, are provided to ensure data integrity. Ultimately, the source serves as a practical tutorial for beginners to master basic database manipulation safely.
