The WhatColumn(s) is the name of one or more columns.
The WhatObject is the name of a table or query.
Each condition is written as a SQL operation using the formula:
Column operator Value
In this case, the WHERE operator resembles the If conditional statement. The Condition1 is the first that would be examined. Remember that, from our discussion earlier, if the first condition is false, the whole statement is false and there is no reason to examine the second condition. If the first condition is true, then the second condition would be examined.
Here is an example:
SELECT Title, Director, CopyrightYear, Rating FROM Videos WHERE CopyrightYear = "1994" AND Rating = "PG-13";
To make the statement easy to use and read, you should include each part of the AND operation in its own parentheses. Here are examples:
SELECT Videos.Title, Videos.Director, Videos.CopyrightYear, Videos.Rating FROM Videos WHERE (Videos.CopyrightYear)="1994") AND ((Videos.Rating)="PG-13");
Here is an example that uses a BETWEEN operator:
BETWEEN [Enter a starting year] AND [Enter an ending year]
