backend-access function

Backend: MS Access

Backend: MS Access

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

Examples

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"))
