What Is UPDATE?

It's time to UPDATE your database! There is something new in town that can help with your data and go a long way for you. Do you know what's cool, or are you still figuring it out? When you write a query, you write an UPDATE statement that changes one of the values in the database. Because some stuff can go wrong when you update data, I will show you how to handle those situations, so your table stays tidy. The UPDATE statement is a SQL UPDATE message that allows you to change or update the values in a table. It's usually suffixed with a WHERE clause to restrict the change to values that meet a specific set of criteria. The UPDATE statement can use the UPDATE statement for a single row or multiple rows in a table. Can use it to edit columns with a new value or delete a column from a table. It also enables you to change the order of columns in a table; like changing the email address and date of birth for someone, you can do it all in one statement. Like Andrew Smith, born on February 17, 1985, and has an email address of asmith@gmail.com, he has changed his name from Andrew Smith to Andrew Smithee. So when Andrew Smith changed his email address in the above example, he was sent to the database as part of a query (the equivalent of UPDATE) that would update his record. So, who's the real boss? The database administrator or the application developer? The answer is both. When you use an application to access and change data, what's happening is that the application sends an UPDATE statement to execute on the database. But it still needs to be granted permission by the database administrator.
