When no query is opened, you can create a new query by clicking New Builder, New SQL, or New Data buttons on the Query page. A new query will be created with the respective view opened. To create a new query when one or more queries are already open, click the button on the query page tab bar. A new query will be created with the same view opened as the previously active query. You can switch to the necessary view by clicking the corresponding button on the right side of the query toolbar.
After this you can use SQL editor or Query Builder to configure your query.
Additionally you can clone an opened query by clicking Clone on the Query toolbar. The query is cloned with all its settings, connection, returned data and the data display settings (grid or chart, chart series, etc.).
