I can call
and this wil give me the metadata for the dataset as well as all the rows.
If the dataset is big, this can take some time and sometime never return. So how can I just return the number of rows in a dataset.
The column name is not always the same, for the dataset can be changed out. Is there a generic 0 or 1 or 2 for the column names
or a call that just returns the metadata, no actuall rows of data.
