Update Query in SQL Description (120 Words):
The UPDATE query in SQL is used to modify existing records in a database table. It allows you to change one or more column values for specific rows that meet a given condition. The basic syntax includes the UPDATE clause, SET to define new values, and a WHERE clause to filter which rows should be updated. If the WHERE clause is omitted, all records in the table will be updated, which can lead to data loss if not used carefully. Common use cases include updating customer details, changing order statuses, or correcting data entries. Mastering the UPDATE statement is essential for maintaining accurate and consistent data in any relational database system.
