1. After you have created your workspace and your project, go to the Project Explorer view in the SAP HANA Development perspective , right-click on the file name, select New, and select File. The New File wizard will appear. 2. Enter or select the parent folder and enter the file name using the following naming convention .procedure. Choose Finish. The icon shows that your procedure is created locally. Choose Save. Your procedure will open containing the default Create Procedure template. In the Properties view, you will see the properties of your procedure, such as Access Mode, Name and Language. You can also change the default schema that this procedure is using. Note: You can also create a folder first and add a file. Right-click on the project name, select New, and select Folder. The New Folder wizard will appear. Enter or select the project, enter the folder name, and choose Finish. 3. To share your project, right-click on the project name, select Team, and select Share Project. The Share Project wizard will appear. Choose Finish. The icon shows that your procedure is not committed and not activated. 4. You can begin writing your code inside your new procedure and save it locally. The syntax is checked simultaneously and is highlighted. Auto-completion of the syntax appears as you type; press Ctrl + Spacebar to get a list of relevant SQLScript statements. Note: You can only write one stored procedure per file. The file name and the procedure name must be the same. 5. To commit your new procedure or make changes to an existing one, first save it, right-click on the procedure, select Team, and select Commit. Your procedure is now synchronized to the repository as a design-time object and the icon shows that your procedure is committed . Caution: The design-time presentation of the procedure is currently in XML format that you must not edit. 6. When you have finished writing your procedure and you are ready to activate it, right-click on the procedure, select Team, and select Activate. Your procedure is created in the catalog as a runtime object and the icon shows that your procedure is activated . This will allow you and other users to call the procedure and debug it. If an error is detected during activation, an error message will appear in the Problems view. Related Links Note: You can also activate your procedure at the project and folder level. SAP HANA Development Perspective [page 25] SAP HANA Repository Packages and Namespaces [page 43] In SAP HANA, a package typically consists of a collection of repository objects, which can be transported between systems.

7.2 Debugging SQLScript The SAP HANA SQLScript debugger allows you to debug and analyze procedures. In a debug session, your procedures will be executed in a serial mode, not in parallel (not-optimized). This allows you to test the correctness of the procedure logic and is not for evaluating the performance. Before you begin using the SAP HANA SQLScript debugger, you must activate your procedures and they must belong to a project on your local work station. For more information, see Editing SQLScript. To debug a procedure in the SAP HANA SQLScript debugger, perform the following steps: 1. Open the Debug perspective in the SAP HANA studio and select the procedure you want to debug by clicking on the relevant tab in the Editor view. 2. Double-click on the left vertical ruler to add breakpoints to your procedure. You can see a list of all of the breakpoints in the Breakpoints view. From the Breakpoints view, you can: ○ Deselect specific breakpoints or skip all of them. ○ Delete a specific breakpoint or delete all. ○ Double-click on a breakpoint to see which line it belongs to in the Editor view. ○ See the status of the breakpoint: ○ Pending ○ Valid ○ Invalid 3. To create a debug session you must first create a debug configuration. Choose and select Debug Configurations.... The Debug Configurations wizard will appear. Note: The current debug configuration allows you to debug any stored procedure that is opened in the editor. Therefore, you do not have to create a new debug configuration for every procedure you want to debug. 4. Double-click SQLScript Procedure, enter a name, choose Apply, and choose Close. SAP HANA Developer Guide Developing Procedures Note: If you want to start debugging your procedure, choose Apply and choose Debug. P U B L I C © 2012 SAP AG. All rights reserved. 161
