dbplyr (version 2.5.0)

backend-impala: Backend: Impala

Description

See vignette("translation-function") and vignette("translation-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.

Usage

simulate_impala()

Examples

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)))
