Click '+' button next to 'Data Frames' and select 'Import Database Data'.

Click Amazon Aurora.

4. Preview and Import

  1. Put data frame name.

  2. Select connection from left box in the dialog.

  3. Write a query in the input field.

  4. Click "Preview" button. Then you will see the preview of the data.

  5. Click "Save" button to import.

5. Using Variables in SQL

First, create a custom R script.

Second, define a variable in the R script and save.

cutoff_date <- "\'2016-01-15\'"

Note that the ‘\’ (backslash) symbols are used to escape the single quotes, which are required to be used for characters in SQL queries.

Finally, you can use @{} to surround a variable name inside the query like below.

select *
from airline_2016_01
where fl_date > @{cutoff_date}
