SELECT * FROM PERFORMERS;

With the Informix row data type capabilities illustrated so far, each individual structured column is defined in isolation. If two tables need to use the same row data type structure, it is defined within each table. This violates one of the key principles of object-oriented design, which is reusability. Instead of having each object (the two columns in the two different tables) have its own definition, the row data type should be defined once and then reused for the two columns. Informix Universal Server provides this capability through its named row type feature. (The row data types shown in previous examples are unnamed row data types.) You create an Informix named row type with the CREATE ROW TYPE statement. Here are examples for the PERSONNEL table:

crystal reports data matrix native barcode generator, excel upc-a, pdf to excel converter in vb.net, c# ean 13 check digit, code 128 barcode font word free, convert image to pdf c# itextsharp

In this statement, I specify that every column the PERFORMERS table should be returned. In addition, every row will be returned because no other clauses have been specified.

CREATE ROW F_NAME M_INIT L_NAME TYPE NAME_TYPE ( VARCHAR(15), CHAR(1), VARCHAR(20));

CREATE ROW TYPE POST_TYPE ( MAIN INTEGER, SFX INTEGER); CREATE ROW STREET CITY STATE POSTCODE TYPE ADDR_TYPE ( VARCHAR(35), VARCHAR(15), CHAR(2), POST_TYPE);

PERFORMER_ID: PERFORMER_NAME: PLACE_OF_BIRTH: INT VARCHAR(60) VARCHAR (60) 2001 2002 2003 2004 2005 2006 2007 2008 2009 Jennifer Warnes Joni Mitchell William Ackerman Kitaro Bing Crosby Patsy Cline Jose Carreras Luciano Pavarotti Placido Domingo Seattle, Washington, USA Fort MacLeod, Alberta, Canada Germany Toyohashi, Japan Tacoma, Washington, United States Winchester, Virginia, United States Barcelona, Spain Modena, Italy Madrid, Spain

Note that the definition of a named row type can depend on other, previously created named row types, as shown by the ADDR_TYPE containing a column (POSTCODE) that uses the POST_TYPE row type. With these row data types defined, the name and address columns in the PERSONNEL table (and any other columns holding name or address data in other tables of the database) can be defined using it. The aggressive use of abstract data types can thus help to enforce uniformity in naming and data typing within an objectrelational database. Here is the new Informix definition of the PERSONNEL table, using the just-defined abstract data types:

Although SQL Server might seem to offer each user a separate operating system thread, the system is actually a bit more sophisticated than that. Because it is inefficient to use hundreds of separate operating system threads to support hundreds of users, SQL Server establishes a pool of worker threads. When a client issues a command, the SQL Server network handler places the command in a queue, and the next available thread from the worker thread pool takes the request. Technically, this queue is a Windows NT/2000 facility called an IOCompletion port. The SQL Server worker thread waits in the completion queue for incoming network requests to be posted to the IOCompletion port. If no idle worker thread is available to wait for the next incoming request, SQL Server dynamically creates a new thread until the maximum configured worker thread limit has been reached. The client s command must wait for a worker thread to be freed. Even in a system with thousands of connected users, most are typically idle at any given time. As the workload decreases, SQL Server gradually eliminates idle threads to improve resource and memory use. The worker thread pool design is efficient for handling thousands of active connections without the need for a transaction monitor. Most competing products, including those on the largest mainframe systems, need to use a transaction monitor to achieve the level of active users that SQL Server can handle without such an extra component. If you support a large number of connections, this is an important capability.

Let s take a closer look at this. The PERFORMERS table includes the PERFORMER_ID, PERFORMER_NAME, and PLACE_OF_BIRTH columns, as shown in Figure 7-1. If you execute the SELECT statement shown in the previous example, your query results would look similar to the following:

PERSONNEL Table NAME EMPL NUM 1234 1374 1421 1532 F NAME Sue Sam Joe Rob M INIT J. F. P. G. L NAME Marsh Wilson Jones Mason STREET 1803 Main St. 564 Birch Rd. 13 High St. 9123 Plain Av.
