SQL Keywords: AND
The AND keyword is used to create a logical conjunction. The formula to follow is:
SELECT WhatColumn(s) FROM WhatObject WHERE Condition1 AND Condition2
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 a conditional statement. The Condition1 is the first that would be examined. 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:
USE VideoCollection1; GO SELECT Title, Director, YearReleased, Rating FROM Videos WHERE YearReleased = N'2006' AND Rating = N'PG-13'; GO
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:
USE VideoCollection1; GO SELECT Title, Director, YearReleased, Rating FROM Videos WHERE (YearReleased = N'2006') AND (Rating = N'PG-13'); GO
Here is an example that uses a BETWEEN operator:
BETWEEN [Enter a starting year] AND [Enter an ending year]
