Backend: Teradata

Source: R/backend-teradata.R
backend-teradata.Rd

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

  • Uses TOP instead of LIMIT

  • Selection of user supplied translations

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

Usage

simulate_teradata()

Examples

library(dplyr, warn.conflicts = FALSE)

lf <- lazy_frame(a = TRUE, b = 1, c = 2, d = "z", con = simulate_teradata())
lf |> head()
#> <SQL>
#> SELECT TOP 6 "df".*
#> FROM "df"
