Backend: MS Access
See vignette("translate-function") and vignette("translate-verb") for
details of overall translation technology. Key differences for this backend
are:
SELECT uses TOP, not LIMIT
Non-standard types and mathematical functions
String concatenation uses &
No ANALYZE equivalent
TRUE and FALSE converted to 1 and 0
Use simulate_access() with lazy_frame() to see simulated SQL without
converting to live access database.
simulate_access()
library(dplyr, warn.conflicts = FALSE) lf <- lazy_frame(x = 1, y = 2, z = "a", con = simulate_access()) lf %>% head() lf %>% mutate(y = as.numeric(y), z = sqrt(x^2 + 10)) lf %>% mutate(a = paste0(z, " times"))
