dbplyr (version 2.5.0)

backend-sqlite: Backend: SQLite

Description

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

  • 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.

Usage

simulate_sqlite()

Arguments

Examples

Run this code
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"))
lf %>% transmute(x = log(b), y = log(b, base = 2))
