See vignette("translation-function") and vignette("translation-verb") for
details of overall translation technology. Key differences for this backend
are:
Uses non-standard
LOG()functionDate-time extraction functions from lubridate
Custom median translation
Right and full joins are simulated using left joins
Use simulate_sqlite() with lazy_frame() to see simulated SQL without
converting to live access database.
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`
