Has anybody had luck calling SQL Stored Procedures from a SnapDevelop API project?  What is best practice and any sample code?  I'm interested in both Resultsets and Output parameters if possible.

Also, in your migration from PB tools, can it figure out that a Datawindow has a Stored Procedure source and generate the right code... Also Stored Procedure Update, Delete and Insert?

Hi Ephraim,

You can choose either .NET DataStore or SqlExecutor to call your SQL Stored Procedures.

1. For .NET DataStore, when generating Model by DataWindow Converter, the following attributes can be applied to the model automatically once needed. Then you can use .NET DataStore to CRUD with your predefined stored procedures similar to PB. Refer to:

DwProcedureAttribute (Retrieve data )

https://docs.appeon.com/appeon_online_help/dwconverter2019r2/api_reference/DWNet.Data/ModelAttribute/Class/DwProcedureAttribute/DwProcedureAttribute.html

DwUpdateAttribute & DwUpdateParameterAttribute (Update, Delete and Insert)

https://docs.appeon.com/appeon_online_help/dwconverter2019r2/api_reference/DWNet.Data/ModelAttribute/Class/DwUpdateAttribute/DwUpdateAttribute.html

https://docs.appeon.com/appeon_online_help/dwconverter2019r2/api_reference/DWNet.Data/ModelAttribute/Class/DwUpdateParameterAttribute/DwUpdateParameterAttribute.html

2. For SqlExecutor provided by SnapObjects ORM, please refer to:

ExecuteProcedure

https://docs.appeon.com/appeon_online_help/snapobjects2.0/api_reference/SnapObjects.Data/SqlExecutor/ISqlExecutor/Method/ExecuteProcedure.html

SelectProcedure

https://docs.appeon.com/appeon_online_help/snapobjects2.0/api_reference/SnapObjects.Data/SqlExecutor/ISqlExecutor/Method/SelectProcedure.html

Regards, Logan

Thanks Logan,

Actually I find the Datawindow converter tool does all the .net code for you.   For Select, Insert, Delete and Update!  Amazing!   Good job Appeon.
