If you execute a query that returns multiple rowsets, the Adaptive Server® Enterprise (ASE) ADO.NET provider version 1.1.548.0 throws an exception when calling the AseDataReader::GetSchemaTable method for the second rowset. The exception is “System.ArgumentException: This row already belongs to another table.” This exception is not thrown if you use version 1.1.475.0. [CR 453942]
