Editing datasets based on a SQL query

One of the major advantages Cloudera Data Visualization provides is the option to edit the data selection that defines the dataset.

Navigate to a dataset that you created based on a SQL query.
Click to open the dataset, on the Dataset Detail view.

There is a SQL text window, which you can edit.
You can restrict rows and columns depending on what you need.
