Backend: Impala
See vignette("translate-function") and vignette("translate-verb") for
details of overall translation technology. Key differences for this backend
are a scattering of custom translations provided by users, mostly focussed
on bitwise operations.
Use simulate_impala() with lazy_frame() to see simulated SQL without
converting to live access database.
library(dplyr, warn.conflicts = FALSE) lf <- lazy_frame(a = TRUE, b = 1, c = 2, d = "z", con = simulate_impala()) lf %>% transmute(X = bitwNot(bitwOr(b, c)))
Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
