This level discusses how to use a database VIEW to simplify your Transact-SQL(T-SQL) code. By understanding how to use a VIEW you will be able to better support writing T-SQL code to meet complex business requirements. In this article I will be discussing what a database VIEW is and then providing a number of examples to help you understand how you can use a VIEW to implement different coding scenarios.

There are times when retrieving data for complex business requirement requires you to temporarily store one or more results sets for a short period of time. Typically these temporary tables are stored in the scope of the current connection, but they may also need to be available across multiple connections.

There are times where you need to write a single T-SQL statement that is able to return different T-SQL expressions based on the evaluation of another expression. When you need this kind of functionality you can use the CASE expression or IIF function to meet this requirement. In this Stairway level Gregory Larsen reviews the CASE and IIF syntax and showing you examples of how the CASE expression and IIF function.

No one wants to use more keystrokes than they have to when they write a chunk of T-SQL code. To help with minimizing the number of characters a T-SQL developer needs to type the Microsoft team introduced three new shortcuts operators when they release SQL Server 2008. These shorts cuts are the String Concatenation, Add EQUALS, and the Subtract EQUALS operators.

There times when you need to write T-SQL code that creates specific T-SQL Code and executes it. When you do this you are creating dynamic T-SQL code. When writing dynamic T-SQL you need to understand how dynamic code opens the possibilities for a SQL injection attack.

When you build applications that store records in SQL Server you will most likely have to store date and time values as part of the data. To manage all the different date related tasks you might need to perform Microsoft has introduced a number of date functions. In this stairway I will be exploring those date and time functions.

When you are writing TSQL code there are times when you want to perform the same logic over and over again. To accomplish this you can used the WHILE keyword. There are other times when you want to perform a conditional test and depending on the results of the test you execute one code block for the TRUE condition and possibly a different code block when the condition is FALSE. When you need to conditionally execute code based on the outcome of a condition you can used the IF keyword. In this Stairway level I will be discussing how to use the WHILE and IF constructs to control the flow of your TSQL code.

Unless you are working on a reporting-only application you will probably need to update tables in your SQL Server database. To update rows in a table you use the UPDATE statement. In this level we will be discussing how to find and update records in your database, and discuss the pitfalls you might run into when using the UPDATE statement.
