Note The Datasource object is included in Commerce Server 3.0 only for backward compatibility with sites created in Commerce Server 2.0. New sites should be constructed using ADOs.
The Execute method executes the specified query and returns the results of the query, if any, in a SimpleList object containing Dictionary objects.
Datasource.Execute(SQL, Parameters)
You can pass the Execute method the text of a query, but this technique does not take advantage of the speed optimizations built into the Content object, and is not advised. If the SQL parameter to Execute is the text of a query, default values are used for the query's timeout, command type, maximum rows fetched, cursor type, and cursor size. The default value for each of these arguments is listed under AddQuery.
