Overview/Description
In SQL Server 2012 you can use Transact-SQL statements to access data in the databases. Transact-SQL statements can be grouped together in a number of ways to create more complex queries when one Transact-SQL statement will not retrieve the desired results. You can group Transact-SQL statements by creating programming objects within a database. These programming objects can include user-defined functions and DML triggers. When creating programming objects Transact-SQL provides control-of-flow keywords to ensure transaction are completed in a specific sequence and...
Overview/Description
SQL Server 2012 allows programming objects to be created to group multiple statements together. These objects work with data in the databases. One type of programming object is the stored procedure. Stored procedures can help reduce network traffic between clients and servers by enabling more than one statement to be set to the server at a time. They do this by executing statements as batches. They also provide greater security. Within stored procedures and other programming objects such as functions and triggers, error handling can be implemented to enable errors to be...

Overview/Description
SQL Server 2012 provides various features and utilities to manage data stored in the databases within a SQL Server instance. This includes support for storing large unstructured data, such as files and documents within or outside the database. The ability to store large data is supported through the FILESTREAM database feature. This enables large unstructured data to be store outside the database on the file system by providing integration between the file system and SQL Server. FileTables is another database feature that allows large data to be store within tables, but...
Overview/Description
Database maintenance is an ongoing task for SQL Server 2012 administrators. This requires the integrity of the database to be checked, the database size to be kept to a minimum by ensuring the files are the correct sizes, and maintenance tasks to be run regularly. SQL Server 2012 Transact-SQL provides DBCC, which is a command that provides statements to maintain the database and database files. An administrator can also create jobs using SQL Server Agent to automate administrative tasks in the SQL Server Database Engine and throughout the enterprise by having the jobs run...
Overview/Description
SQL Server 2012 provides features to allow administrators to ensure that data is accessed efficiently, this includes the use of indexes, table and index partitions, and full-text search. Indexes in SQL Server 2012 database allow data to be accessed quickly using keys that are stored in a B-tree structure. Indexes need to be created and managed to ensure for the best database performance. SQL Server 2008 provides table and index partitioning to allow data to be stored across multiple filegroups within a database. This makes tables and indexes that contain large amounts of...
Overview/Description
XML has been integrated into SQL Server 2012 so that XML data can be stored within databases using the xml data type. SQL Server 2012 also allows for relational data already stored in a database to be changed to XML, and for data to be loaded as XML using various methods. You can query this data using the XQuery language within the XML data type methods. SQL Server 2012 also provides support for using FOR XML to extract relational data from a database in XML format and the use of OPENXML to generate relational views from XML. This course demonstrates how to use the xml...
Overview/Description
Microsoft SQL Server 2012 Transact-SQL offers advanced query techniques, such as built-in aggregate, analytic, scalar, and ranking functions, as well as common table expressions, or CTEs and derived tables to manipulate the result set for a query.
