The UPDATE command in SQL is used to modify existing records in a database table. It allows you to change one or more columns for specific rows that meet a certain condition, defined by the WHERE clause. For example, UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition; updates the specified columns for all rows that meet the condition. If no WHERE clause is provided, all rows in the table will be updated.
