This tutorial uses Transact-SQL, the Microsoft implementation of the. SQL standard. . create views and stored procedures and configure a user to the database and the data. This tutorial is divided into .. this instance of SQL. Server The implementation of stored procedures and UDFs using the. Common models of replication, and serves as a tutorial for how to configure publications SQL Server SP2, this data type can be stored as a variable-length column by. tended stored procedures (XPs), common-language-run- time stored procedures (CLRPs, new to SQL Server [1]), and interpreted stored procedures (SPs).

This file contains all the accompanying code and script developed for the book. It also includes pre-built versions of all the XPs to quickly get you up and running.

Please note that you are obliged to download a copy of the book to use this code. Chapter Breakdown The book is comprised of 29 chapters with the breakdown as follows: The initial chapters provide an introduction to XPs.

Then we develop a class framework to make the development process simpler. The chapters in the middle of the book include loads of ready to run production quality XPs. Finally the remainder of the book provides a comprehensive primer on the various technologies in SQL Server which XP's build upon.

Determine when to use stored procedures vs. SQL in the code

It also details the low level API's involved. Some simple tutorials are also provided to get started creating your own XPs.

Like any class framework, the idea is to reduce the amount of boilerplate code which you the developer must write in order to develop your solution. Here is an example that uses a procedural approach to displaying the contents of the Employee table: Open the Employee table Loop until we reach the end of the Employee table.


The how part is left up to SQL Server to figure out. TSQL is highly optimized for its declarative statements, like the SELECT statement in the example above, and most data retrieval needs can be performed using the declarative capabilities of TSQL; but, on some occasions, loops, branching, and other procedural approaches are needed. If you find yourself needing to use cursors or other procedural approaches, consider writing your stored procedure in.

But, before you do, think carefully about how you might use a declarative approach, instead. If you can write your stored procedures using declarative statements, instead, they will run faster—and very often much faster. Net is when a stored procedure must perform some non-database task.

I will use this second reason as a backdrop for the demo in this post. They want to send a notification to a server whenever data in the Employee table change.

The notification must include the BusinessEntityID primary key of the row that changed. To address this need, a CLR stored procedure that does exactly that will be created.

You can also use Visual Studio , , or We will use Visual Studio to create the.

Because we will be deploying to a newer version of SQL Server from an older version of Visual Studio, we will encounter a database version issue and the deploy will fail. The demo shows how to work around this common problem. Select New Project.

We are going to develop our. Net code using C , but notice that you also have the option to use Visual Basic. Then click the OK button. Since this is a database project, you will need to select a database to which the procedure we are about to create will become attached. After you specify a SQL Server in the Server name textbox, the databases on that server will appear in the drop-down below, the one prompting you to Select or enter a database name.

SQL Server Stored Procedure Tutorial

A new database project that is connected to the database we specified has been created and we can see its components in the Solution Explorer window. Note that you can create code for different types of database objects; you are not limited to stored procedures.

Note the new stored procedure that is listed in Solution Explorer. Note the [Microsoft.

SqlProcedure] attribute that is necessary for a CLR procedure. Note also the SqlString datatype.The specific tradeoffs depend on your application. A stored procedure is nothing more than prepared SQL code that you save so you can reuse the code over and over again.

The end result allows you to concentrate on coding your domain specific code as well as improve the overall robustness of the end solution. In addition to being a great tool for command-line aficionados, bcp is a powerful tool for those seeking to insert data into a SQL Server database from within a batch file or other programmatic method.

Properties of sub query can be defined as A sub query should not have order by clause A sub query should be placed in the right hand side of the comparison operator of the main query A sub query should be enclosed in parenthesis because it needs to be executed first before the main query More than one sub query can be included 8. Triggers are used to execute a batch of SQL code when insert or update or delete commands are executed against a table.

Create a fixed-width file for exporting SQL Server data Exporting SQL Server data to a file from within a stored procedure is a common task, but there are different ways to do this -- none of which are very easy. If a user is able to login then it needs to check user table if the user is present it return success and retrieve the data which user has access.

Thursday, January 28, - 3: It's also used when dealing with something that needs to be assembled almost entirely from scratch; For instance when the number and variety of parameters, the tables being queried, and so on may vary from statement to statement.
