Here is another example of assertion that might be useful in the sample database: Insure that the total of the orders for any customer does not exceed their credit limit: CREATE ASSERTION credit_orders CHECK (CUSTOMER.CREDIT_LIMIT <= SELECT SUM(ORDERS.AMOUNT) FROM ORDERS WHERE ORDERS.CUST = CUSTOMER.CUST_NUM) As these examples show, a SQL2 assertion is defined by a search condition, which is enclosed in parentheses and follows the keyword CHECK. Every time an attempt is made to modify the contents of the database, through an INSERT or UPDATE or DELETE statement, the search condition is checked against the (proposed) modified database contents. If the search condition remains TRUE, the modification is allowed. If the search condition would become untrue, the DBMS does not carry out the proposed modification, and an error code is returned, indicating an assertion violation. In theory, assertions could cause a very large amount of database processing overhead as they are checked for each statement that might modify the database. In practice, the DBMS will analyze the assertion and determine which tables and columns it involves. Only changes that involve those particular tables or columns will actually trigger the search condition. Nonetheless, assertions should be defined with great care to insure that they impose a reasonable amount of overhead for the benefit they provide.

The types of constraints that can be specified in SQL2, and the role played by each, can be summarized as follows: The NOT NULL constraint can appear only as a column constraint It prevents the column from being assigned a NULL value A PRIMARY KEY constraint can appear as a column constraint or a table constraint If the primary key consists of a single column, the column constraint may be more convenient If it consists of multiple columns, it should be specified as a table constraint A UNIQUE constraint can appear as a column constraint or a table constraint If the unique values restriction is being enforced for a single column only, the column constraint is the easiest way to specify it.

The CASE function/expression works much like a Select statement with nested If statements. In fact, most of the time you can write equivalent code using nested If statements. There are two types of CASE function/expressions:

A simple CASE function/expression has the following syntax:

Now you will need to fire-up your PC and load the supplied disk into your computer. Once the communication cable has been attached, you will now need to load the STAMP2X or the STAMPW.EXE programs. These are the editor programs you will need to load the Data-Alert programs into the microprocessor. There are two Data-Alert programs included with this project: the DATA.BS2 program (Listing 21-1), which is the basic data reporting program, and MODEMTIME.BS2 (Listing 21-2), which reports data along with the time of day. Scroll down the displayed program, look for the simulated phone number, and replace it with your own phone number. Remember, a digit 10 is programmed by a zero. If you want to dial a long distance number, just add the full sequence of numbers. If you wish to dial out from a PBX telephone system, you will need to first put in the access number such as an 8 or 9 followed by a comma,

If the unique values restriction applies to a set of two or more columns (that is, the combination of values for those columns must be unique for all rows in the table), then the table constraint form should be used A referential (FOREIGN KEY) constraint can appear as a column constraint or a table constraint If the foreign key consists of a single column, the column constraint may be more convenient If it consists of multiple columns, it should be specified as a table constraint If a table has many foreign key relationships to other tables, it may be most convenient to gather all of its foreign key constraints together at one place in the table definition, rather than having them scattered throughout the column definitions A CHECK constraint can appear as a column constraint or a table constraint.

CASE input_expression WHEN when_expression THEN result_expression [...n] [ ELSE else_result_expression ] END

The previous example used this kind of CASE function/expression. SQL Server attempts to match the input_expression with one of the when_expressions. If it is successful, it returns the result_expression associated with the first matching when_expression. An Else clause is also part of the CASE function/expression. If the value of the input_expression is not equal to either of the when_expressions, the function returns the value of the else_result_expression.
