See vignette("translate-function") and vignette("translate-verb") for details of overall translation technology. Key differences for this backend are:

  • Uses non-standard LOG() function

  • Date-time extraction functions from lubridate

  • Custom median translation

Use simulate_sqlite() with lazy_frame() to see simulated SQL without converting to live access database.

simulate_sqlite()

Examples

library(dplyr, warn.conflicts = FALSE) lf <- lazy_frame(a = TRUE, b = 1, c = 2, d = "z", con = simulate_sqlite()) lf %>% transmute(x = paste(c, " times"))
#> <SQL> #> SELECT `c` || ' ' || ' times' AS `x` #> FROM `df`
lf %>% transmute(x = log(b), y = log(b, base = 2))
#> <SQL> #> SELECT LOG(`b`) AS `x`, LOG(`b`) / LOG(2.0) AS `y` #> FROM `df`
