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

simulate_redshift()
Examples
library(dplyr, warn.conflicts = FALSE)
lf <- lazy_frame(a = TRUE, b = 1, c = 2, d = "z", con = simulate_redshift())
lf %>% transmute(x = paste(c, " times"))
lf %>% transmute(x = substr(c, 2, 3))
lf %>% transmute(x = str_replace_all(c, "a", "z"))
