First, you must modify the stored procedure created in the SQL adapter sample to help derive the schema of the returned data.

This topic shows you how to do the following:

1. Modify a stored procedure.
   
   
2. Create an empty BizTalk project.
   
   
3. Add metadata to the BizTalk project.
   
   
4. Revert the stored procedure.
   
   
5. Add a required schema to the project.
   
   
6. Create an orchestration.
   
   
7. Create a map.
   
   
8. Create new messages.
   
   
9. Build the project.
   
   
10. Create a strong name key file.
    
    
11. Deploy the solution.
    
    
12. Create a send port to communicate with the SQL adapter in BizTalk Explorer.
    
    
13. Create a receive location by using BizTalk Explorer.
    
    
14. Bind ports.
    
    
15. Start an orchestration.
    
    

You must build and initialize the SQL adapter sample to be able to view the Loan Acceptance sample. For more information about installing the SQL adapter sample, see SQL Adapter Loan Application.

Once installed, the Loan Acceptance project is located in the <drive>:\Program Files\Microsoft BizTalk Server 2009\SDK\Sample\Adapter\SQLAdapter\Loan Acceptance folder.

1. Click Start, point to All Programs, point to Microsoft SQL Server 2005, and then click SQL Server Management Studio.

2. When prompted, connect to the SQL Server instance that contains the BTS2009_SQL_Adapter_Loans database.

3. In SQL Server Management Studio, in the left pane, expand Databases, expand BTS2009_SQL_Adapter_Loans, expand Programmability and then click Stored Procedures.

4. In the right pane, right-click SP_Save_Loan_info and click Script Stored Procedure As, ALTER To, New Query Editor Window.to edit the stored procedure text.

5. Add the text , xmldata to the last statement in the stored procedure so that the last statement reads as follows:

   select * from Loans where LoanID = @newLoanID for xml auto, xmldata.

   Note

   The SQL adapter only handles stored procedures that return XML. In this example, there is one simple SELECT FROM table FOR xml auto. Examine the stored procedure SP_Get_Agent_and_Interest() for a procedure that returns one or two items that you need for XML raw data. The added , xmldata would cause the SQLXML to emit a schema as well as data. The SQL Add Adapter Wizard uses , xmldata, which you must remove before actual operation of the SQL adapter or else the schema will confuse the BizTalk Messaging Engine.

6. On the Query menu, click Execute to modify the stored procedure.

1. Click Start, point to All Programs, point to Microsoft Visual Studio 2008, and then click Microsoft Visual Studio 2008.

2. On the File menu, point to New, and then click Project.

3. In the New Project dialog box, in the Project Types section, click BizTalk Projects, and then in the Templates section, click Empty BizTalk Server Project.

4. In the Name box, type SQL_Adapter_SP, and then click OK.

   The new SQL_Adapter_SP project appears.

1. In Visual Studio, in Solution Explorer, right-click SQL_Adapter_SP, point to Add, and then click Add Generated Items.

2. In the Add Generated Items – SQL_Adapter_SP dialog box, in the Templates section, click Add Adapter Metadata, and then click Add.

3. In the Add Adapter Wizard, on the Select Adapter page, select SQL from the list of registered adapters, and click Next.

   You can leave the other entries on the page blank or with their default values, unless you are connecting to a remote SQL Server computer. If connecting to a remote SQL Server computer, type the name of the server in the SQL Server box, and the name of the database in the Database box. Leave the Port box empty.

4. On the Database Information page, click Set.

5. In the DataLink Properties dialog box, on the Connection Tab, do the following.

   Use this	To do this
   Select or enter a server name	Type localhost.
   Enter information to log onto the server	Select Use Windows NT Integrated security.
   Select the database on the server	Select BTS2009_SQL_Adapter_loans from the drop-down menu.

6. Click OK.

   This sets the connection string for the SQL adapter.

   Note
   This connection is stored only when you run this wizard. The actual connection will be formed later during the port binding process.

7. Click Next.

8. On the Schema Information page, do the following.

   Use This	To do this
   Target namespace	Type http://Microsoft.Sample.SQLAdapter.
   Select the port type	Select Send port.
   Request root element name	Type MyRequestRoot.
   Response root element name	Type MyResponseRoot.

   Note
   Write this information down. You will need it later. Take note that everything you type is case-sensitive, for example, SQLAdapter is not the same as SQLadapter.

9. Click Next.

10. On the Statement Type Information page, select Stored Procedure, and then click Next.

11. On the Statement Information page, select SP_Save_Loan_info from the drop-down box.

12. On the Parameter values page, click once to the right of the check box in a cell in the Value column to select the cell, then wait for one or two seconds and click again to the right of the check box to edit the cell. Ensure that the check box is not checked as the check box sets the value to NULL. Repeat this procedure for each cell in the Value column and enter the following values.

    Use this	To do this
    Value cell of the @Amount row	Type 100.
    Value cell of the @City row	Type Redmond.
    Value cell of the @FirstName row	Type Max.
    Value cell of the @LastName row	Type Benson.
    Value cell of the @State row	Type WA.
    Value cell of the @Street row	Type 123 Main St.

    Note
    The check box sets the argument to NULL.

    Note
    Clicking twice in one place will toggle the NULL value check box.

    Note
    The arguments entered in this step are stored only for schema generation. The actual arguments during operation will be in a solicit-request message.

13. Click Generate.

    Completed Statement Information page
    

14. Click Next, and then click Finish to complete the wizard.

    The Add Adapter Wizard generated and added two files to your project, BizTalk Orchestration.odx and SQLService.xsd. SQLService.xsd is the schema containing both the Request and Response structures. BizTalk Orchestrations.odx is a blank orchestration with some preconfigured port types.

    New files created in the BizTalk project
    

    Note
    If you know that the stored procedure only returns one row (as in this example), adjust properties of elements in the response schema from the default: Max Occurs=unbounded ; Min Occurs=0.

15. Now go back to SQL Server Management Studio and return the stored procedure to its original state.

1. In the right pane, right-click SP_Save_Loan_info and click Script Stored Procedure As, ALTER To, New Query Editor Window.to edit the stored procedure text.

2. Remove the text , xmldata from the last statement in the stored procedure so that the last statement reads as follows:

   select * from Loans where LoanID = @newLoanID for xml auto

3. On the Query menu, click Execute to modify the stored procedure.

1. In Visual Studio, on the Project menu, click Add Existing Item.

2. In the Add Existing Item - SP_Adapter_SP dialog box, browse to <drive>:\Program Files\Microsoft BizTalk Server 2009\SDK\Samples\AdapterUsage\SQLAdapter\Loan Acceptance, select LoanApplication.xsd, and then click Add.
