backend-oracle function

Backend: Oracle

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

• Use FETCH FIRST instead of LIMIT
• Custom types
• paste() uses ||
• Custom subquery generation (no AS)
• setdiff() uses MINUS instead of EXCEPT

Note that versions of Oracle prior to 23c have limited supported for TRUE and FALSE and you may need to use 1 and 0 instead. See https://oracle-base.com/articles/23c/boolean-data-type-23c for more details.

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

simulate_oracle()

Examples

library(dplyr, warn.conflicts = FALSE)

lf <- lazy_frame(a = TRUE, b = 1, c = 2, d = "z", con = simulate_oracle())
lf %>% transmute(x = paste0(c, " times"))
lf %>% setdiff(lf)
