Dataset array with numeric and boolean data

Hello everyone!!!

I have a dataset array with numeric columns and boolean columns (0/1).Boolean columns are in string format ('0'/'1').

I want to find in this dataset array the rows where a boolean column has '1' values.

Can you help me with that?

Thank you!! Vanessa

Please explain the calls and size of the "dataset". This would be more useful that letting the readers guess this important detail.
