Use the default finder
An intuitive way to query is by using the four tag level lists of the default finder in the Finder tab. This finder shows all the data tables available in your domain. You can use the time buttons above the tag level lists to display only tables that have received data over the last day, last week...

Once you select the final level of the tag, the query window will open displaying the contents of the selected data table.

To do this, select the Column Operations available in the query window to further customize the display of columns in your table.icon on the final level of the tag and choose Show / Hide Columns. This opens a window that lets you select the columns you want to show (checked) and the ones you want to hide (unchecked). Click Apply and the table opens in the query window showing only the columns you selected. You can use the
