Using XML in SQL Server 2008: Relational Data As XML - The FOR XML Modes (part 4) - EXPLICIT Mode

FOR XML EXPLICIT is a powerful, oft-maligned, somewhat daunting mode of SQL Server XML production. It allows for the shaping of row data in any desirable XML structure, but the SQL required to produce it can easily end up being hundreds (or, in some cases, thousands) of lines long, leading to a potential maintenance headache.

Using XML in SQL Server 2008: Relational Data As XML - The FOR XML Modes (part 3) - AUTO Mode

When RAW mode is not enough, FOR XML AUTO provides a few more ways to shape your XML output. Its usefulness derives from its capability to produce nested XML elements from rows derived by joining multiple tables, in contrast to the flat structure of RAW mode.

Programming with SQL Azure : WCF Data Services (part 1)

WCF Data Services, formerly known as ADO.NET Data Services, enables the creation and consumption of OData services. OData, the Open Data Protocol, is a new data-sharing standard that allows for greater sharing of data between different systems.

Using XML in SQL Server 2008: Relational Data As XML - The FOR XML Modes (part 2) - Working with Binary Columns

Even though XML is purely a text-based markup language, FOR XML still has the capability to generate XML that contains data selected from binary–data-typed columns, such as image, binary, and varbinary. To do this, SQL Server base-64 encodes the data, resulting in a long character string.

Using XML in SQL Server 2008: Relational Data As XML - The FOR XML Modes (part 1) - RAW Mode

When specified at the end of a SELECT statement, the keywords FOR XML RAW tell SQL Server to generate a one-XML-element-per-row structure. The FOR XML statement has a few options that change its output from the default of document fragments to well-formed documents with a slightly reshaped structure.

Programming with SQL Azure : Connecting to SQL Azure (part 4) - Sqlcmd

If you've worked with SQL Server for any length of time, chances are you've worked with the sqlcmd utility. This utility lets you enter and execute T-SQL statements and other objects via a command prompt.

Programming with SQL Azure : Connecting to SQL Azure (part 3) - ODBC

There is nothing earth-shattering or truly groundbreaking here, but let's walk though an example to see how ODBC connections work and illustrate that your ODBC classes still work as you're used to.

Programming with SQL Azure : Connecting to SQL Azure (part 2)

As you become more and more familiar with SQL Azure, you'll find that you don't need to make a lot of changes to your application code except possibly any inline T-SQL.

Programming with SQL Azure : Connecting to SQL Azure (part 1) - ADO.NET

Developing applications that work with SQL Azure isn't rocket science, but it requires knowing what to expect and what functionality you have to work with. You read earlier that not all client libraries work with SQL Azure and saw the libraries that are supported.

Programming with SQL Azure : Application Deployment Factors

Each of those aspects is important and should be discussed when you're considering moving applications to the cloud. In addition to security, performance is one of the primary items of concern that companies have about cloud computing.

SQL Server 2008: SQL Server Web Services - Building Web Services (part 3)

The second major section of the DDL begins after the end parenthesis of the AS clause, with the FOR SOAP group, whose keywords appear in parentheses.

SQL Server 2008: SQL Server Web Services - Building Web Services (part 2)

The AS HTTP statements describe the protocol, ports, virtual path, and TCP/IP bindings for the endpoint. This keyword group is of interest to security professionals because this is where you can implement IP restrictions, authentication, and other lockdown mechanisms.

SQL Server 2008: SQL Server Web Services - Building Web Services (part 1)

To expose this procedure as a web method of your web service, you use the CREATE ENDPOINT T-SQL statement, which falls under the formal SQL category of Data Definition Language (DDL).

SQL Server 2008: SQL Server Web Services

Microsoft first made it possible to expose T-SQL query batches, stored procedures, and scalar-valued functions as web services with the release of SQLXML 3.0, an add-on package for SQL Server 2000 that allowed for the interchange of relational data as Extensible Markup Language.

SQL Server 2008: SQL Server Service Broker - Related System Catalogs

A few of the system catalogs and dynamic management views (DMVs) might be of interest to you if you’re debugging Service Broker applications or simply seeking a greater understanding of how Service Broker works under the hood. Let’s take a look at some of them.

SQL Azure Backup Strategies (part 2)

The question then becomes, how do you know the copy is finished? The answer is that Microsoft created a new data management view (DMV) to return the details of the database copy operation

SQL Azure Backup Strategies (part 1) - Copying a Database

Your data is in the cloud, but it really doesn't stop there. Much of the functionality that DBAs have at their fingertips when dealing with local data stores doesn't exist in the cloud yet

SQL Server 2008: Troubleshooting SSB Applications with ssbdiagnose.exe

SQL Server 2008 comes with a new command-line application, ssbdiagnose.exe. You use this advanced utility to monitor SSB conversations or to check application configuration status, both across databases and between computers.

SQL Server 2008: Service Broker Routing and Security

Service Broker services running on multiple SQL Server instances communicate across the network via endpoints that are secured using certificates. Certificates are the foundation of secure network communications.

Migrating Databases and Data to SQL Azure (part 9)

The next step is to copy the data into the cloud—specifically, to your SQL Azure TechBio database. The syntax for copying into a database is very similar to the syntax for copying data out

Migrating Databases and Data to SQL Azure (part 8)

The bcp utility provides bulk copying of data between instances of Microsoft SQL Server. This utility is installed with SQL Server and requires no knowledge or understanding of T-SQL syntax

Understanding Service Broker Constructs (part 5)

After you create the initiator, the next step is to create the service program in XCatMgmt that is activated when messages arrive. This step involves a bit more work because this program needs to receive messages of at least three types

Understanding Service Broker Constructs (part 4) - Creating the Conversation Initiator

Each time Windows 7 starts successfully in Normal mode, the system makes a note of which control set—the system’s drivers and hardware configuration—was used.

Migrating Databases and Data to SQL Azure (part 7)

You're now ready to test your SSIS package. In Visual Studio, click the green arrow on the toolbar to begin package execution. Execution starts at the Clear Data task—which, as you recall, deletes all the data from the UserDocs, Users, and Docs tables
