It is also the only kind of constraint that forms part of the definition of a domain or an assertion The check constraint is specified as a search condition, like the search condition that appears in the WHERE clause of a database query The constraint is satisfied if the search condition has a TRUE value..

A searched CASE function/expression is very similar. The only difference is that it does not have an input_expression. The complete criteria are inside the When clause in the form of a Boolean expression:

Phone line J3-1 J3-2 J3-3 J3-4

SQL Server returns the result_expression associated with the first Boolean_expression, which is True. If all Boolean_expressions are false, SQL Server returns the else_result_expression. In the following example, a searched CASE function/expression has to be used because the Boolean_expressions have different operators (= and Like):

- 228 -

Create Procedure prListLeaseInfo -- list all lease contract information As Select LeaseVendor [Lease Vendor], LeaseNumber [Lease Number], CASE -- some vendors have id of sales reps -- incorporated in lease numbers When LeaseVendor = 'Trigon FS' THEN SUBSTRING( LeaseNumber, When LeaseVendor Like 'EB%' THEN SUBSTRING( LeaseNumber, When LeaseVendor Like 'MMEX%' THEN SUBSTRING( LeaseNumber, When LeaseVendor = 'DAFS' THEN SUBSTRING( LeaseNumber, Else 'Unknown' end [Lease Agent], ContractDate [Contract Date] from Lease

J3-4 J3-3 J3-2 J3-1

5, 12) 9, 8) 7, 6) 8, 11)

TIP: Although both examples use CASE functions/expressions as a part of the Select statement, keep in mind that you can use it anywhere that you can place an expression. This flexibility might come in very handy in some situations.

Each individual constraint within a database (no matter what its type) may be assigned a constraint name to uniquely identify it from the other constraints. It's probably not necessary to assign constraint names in a simple database where each constraint is clearly associated with a single table, column, or domain, and where there is little potential for confusion. In a more complex database involving multiple constraints on a single table or column, it can be very useful to be able to identify the individual constraints by name (especially when errors start to occur!). Note that the check constraint in an assertion must have a constraint name; this name effectively becomes the name of the assertion containing the constraint.

Getting Information About Data You can use numerous functions to return information about data, the most important of which are

'DATA.BS2 flash new_io_state old_io_state call_state io timer tpin Tele TXpin M0 M1 LedPin Siren Lamp recall_delay bdmd delay

ISDATE is a function that you can use to determine whether a character value or expression contains a valid date. It is particularly useful when you are forced to read data from text files. If the result of this function is 1 (true), SQL Server guarantees that you will be able to convert the data to date and time datatypes. ISDATE uses the following syntax:

In their simplest form, the various constraints that are specified within a database are checked every time an attempt is made to change the database contents that is, during the execution of every attempted INSERT, UPDATE, or DELETE statement For database systems claiming only Intermediate level or Entry level conformance to the SQL2 standard, this is the only mode of operation allowed for database constraints The Full level SQL2 standard specifies an additional capability for deferred constraint checking When constraint checking is deferred, the constraints are not checked for each individual SQL statement Instead, constraint checking is held in abeyance until the end of a SQL transaction (Transaction processing and the associated SQL statements are described in detail in the next chapter) When the completion of the transaction is signaled by the SQL COMMIT statement, the DBMS checks the deferred constraints.

ISDATE(expression)

init: DIRL = %00000000 DIRH = %11111111 high M0 high M1 new_io_state = %00000000 old_io_state = %00000000

In the following stored procedure, SQL Server verifies that Lease Data (received as a string) can be converted to a datetime value. It then stores this result with the rest of the parameters in the Lease table:

Create Procedure prLoadLeaseContract -- insert lease contract information and return id of lease @chvLeaseVendor varchar(50), @chvLeaseNumber varchar(50), @chvLeaseDate varchar(50), @intLeaseId int OUTPUT As Declare @intError int -- test validity of date if ISDATE(@chvLeaseDate) = 0 begin Raiserror ("Unable to Convert to date.", 16, 1) return 1
