library(DBI)

con <- dbConnect(RSQLite::SQLite())
dbWriteTable(con, "df1", data.frame(x = c(1, 2)))
dbWriteTable(con, "df2", data.frame(x = c(2, 3)))

dbGetQuery(con, "SELECT COALESCE(df1.x, df2.x) FROM df1 FULL JOIN df2 ON df1.x = df2.x")
#>   COALESCE(df1.x, df2.x)
#> 1                      1
#> 2                      2
#> 3                      3

And also RIGHT JOIN, for more than half a year already. I like them mentioning "long overdue":

Add (long overdue) support for RIGHT and FULL OUTER JOIN.
