Public Overloads Function ExecuteDataSet() As DataSet

public DataSet ExecuteDataSet()

Return Value

Not all providers return a DataSet with the same structure if no results are returned by the query. Some providers return an empty DataSet. Some providers return a DataSet with a single DataTable which contains zero rows. Test for tables and rows using the Count property on the DataSet and any DataTables before assuming any Tables or Rows exist. 

In no case will the DataSet returned be a null reference (Nothing in Visual Basic).
