Use cell magics - Amazon Athena
%%sql

Magics that are written on several lines are preceded by a double percent sign (%%) and are called cell magic functions or cell magics.

%%sql

This cell magic allows to run SQL statements directly without having to decorate it with Spark SQL statement. The command also displays the output by implicitly calling .show() on the returned dataframe.

Using %%sql.

The %%sql command auto truncates column outputs to a width of 20 characters. Currently, this setting is not configurable. To work around this limitation, use the following full syntax and modify the parameters of the show method accordingly. 

spark.sql("""YOUR_SQL""").show(n=number, truncate=number, vertical=bool)

  • n int, optional. The number of rows to show.

  • truncate – bool or int, optional – If true, truncates strings longer than 20 characters. When set to a number greater than 1, truncates long strings to the length specified and right aligns cells.

  • vertical – bool, optional. If true, prints output rows vertically (one line per column value).
