backend-mysql: Backend: MySQL/MariaDB

In dbplyr: A 'dplyr' Back End for Databases

Backend: MySQL/MariaDB

Description

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

• paste() uses CONCAT_WS()

• String translations for str_detect(), str_locate(), and str_replace_all()

• Clear error message for unsupported full joins

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

Usage

simulate_mysql()

simulate_mariadb()

Examples

library(dplyr, warn.conflicts = FALSE)

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