In dplyr 0.7.0, a number of database and SQL functions moved from dplyr to dbplyr. The generic functions stayed in dplyr (since there is no easy way to conditionally import a generic from different packages), but many other SQL and database helper functions moved. If you have written a backend, these functions generate the code you need to work with both dplyr 0.5.0 dplyr 0.7.0.

check_dbplyr()

wrap_dbplyr_obj(obj_name)

Examples

if (requireNamespace("dbplyr", quietly = TRUE)) {
wrap_dbplyr_obj("build_sql")
wrap_dbplyr_obj("base_agg")
}
#> base_agg <- function () 
#> {
#>     if (utils::packageVersion("dplyr") > "0.5.0") {
#>         dplyr::check_dbplyr()
#>         dbplyr::base_agg
#>     }
#>     else {
#>         dplyr::base_agg
#>     }
#> }
