Mini-Quiz: Updating Data with SQL

by Ron Kurtus (16 June 2007)

Take this Mini-Quiz to check your understanding of the lesson material.



1. Why would the ID be usually used in the WHERE command for updating a specific item?

So that you can easily change the ID

You should never use the ID in the WHERE statement

Each ID is unique, while other items may not be unique

2. How do you separate items in the SET command?

With a comma

With a semi-colon

With quotation marks

3. When should you omit using the WHERE command?

When you want to change all items in the designated columns

You should always omit WHERE, because it takes up more code

When you want to insert a NULL item

If you got all three correct, you are on your way to becoming a Champion in Using SQL. If you had problems, you had better look over the material again.
