4. 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}
