Open the WaitForDelayVisitor.cs file and update the contents to match the following code: using The WaitForDelayVisitor.cs file is added to the project in Solution Explorer. In the Name text box, type WaitForDelayVisitor.cs and then click the Add button. In Solution Explorer, select the SampleRules project. These might be difficult to find using the object model since they're not associated to a specific object property or relationship, but it's easy to find them using the visitor pattern and the ScriptDom API.

In this API, Transact-SQL code is represented as an abstract syntax tree (AST) and visitor classes can be useful when you wish to find specific syntax objects such as WAITFORDELAY statements. Visitor classes make use of the ScriptDom APIs provided by SQL Server. This class provides access to the WAITFOR DELAY statements in the model. The first class that you must define is the WaitForDelayVisitor class, derived from TSqlConcreteFragmentVisitor. These classes might be useful for creating additional custom rules. Creating the Custom Code Analysis Rule Supporting Classesīefore you create the class for the rule itself, you will add a visitor class and an attribute class to the project. Next you will add supporting classes that will be used by the rule. For Visual Studio 2013 this will usually be C:\Program Files (x86)\\MicrosoftVisual Studio 12.0. For Visual Studio 2012 the will usually be C:\Program Files (x86)\\MicrosoftVisual Studio 11.0.

Choose the, .dll, and .Sql.dll entries and click Add, then click OK.ĭACFx binaries are now installed inside your Visual Studio install directory. Click Browse and navigate to the \Common7\IDE\Extensions\\Microsoft\SQLDB\DAC\120 directory. Next install the required DACFx references. Select on the Frameworks tab.Ĭlick Browse and navigate to the C:\Program Files (x86)\MicrosoftSQL Server\120\SDK\Assemblies directory, select .dll, and the click OK. In Solution Explorer, right-click the project node and then click Add Reference. Rename the file Class1.cs to AvoidWaitForDelayRule.cs. To create a class library project:Ĭreate a Visual C# or Visual Basic class library project named SampleRules. Creating a Custom Code Analysis Rule for SQL Serverįirst create a class library.

You are also expected to be familiar with Visual Studio concepts, such as how to create a class library and how to use the code editor to add code to a class. This walkthrough is intended for users who are already familiar with the SQL Server features of SQL Server Data Tools. You must have a SQL Server project that contains SQL Server objects.Īn instance of SQL Server to which you can deploy a database project. You must have installed a version of Visual Studio that includes SQL Server Data Tools and supports Visual C# or Visual Basic development. You need the following components to complete this walkthrough: Verify that the new code analysis rule is in place. In this walkthrough, you will create a custom rule for Transact-SQL static code analysis by using the following processes:Ĭreate a class library, enable signing for that project, and add the necessary references.Ĭopy the resulting DLL that you create into the Extensions directory in order to install it. The rule created in this walkthrough is used to avoid WAITFOR DELAY statements in stored procedures, triggers, and functions. This walkthrough demonstrates the steps used to create a SQL Server Code Analysis rule.
