Issues with dplyr::mutate and RMySQL.

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = " # "
)
options(width =100)

library('dplyr')
packageVersion('dplyr')
packageVersion('RMySQL')

my_db <- src_mysql('mysql','127.0.0.1',3306,'root','passwd')
d4 <- copy_to(my_db,data.frame(x=c(1.1,2,3,3)),'d4')
suppressWarnings(
  d4 %>% mutate(z=1) %>% compute() -> d4
)
print(d4)
