Remarks

This class is used for SQL Pass Through and makes it possible for you to execute stored procedures on a host database such as Microsoft SQL Server.

To use, drop the class on a project or form or, from the Component Gallery Item Shortcut Menu, select Add to Project or Add to Form. When you drop the class on a form, Visual FoxPro places the class icon on the form. You can then specify the appropriate property values and provide any necessary input and output objects. When you drop the class on a project, you can choose between adding the class or creating a subclass.

You need to add code that specifies parameter and connection information so the class can return a result set in a cursor.
