Announcing full support for the Snowflake driver

In the previous release we included a preview of the Snowflake driver. This new release provides full ODBC, dbplyr, and Python support for Snowflake, as well as corrects some issues that occurred on new installations.

This release makes working with the Snowflake data cloud as easy as working with other supported data sources. For example, the same dplyr syntax used with data in R will also work with data in Snowflake. In the code below, data from the nycflights13 package were pre-loaded into a Snowflake data warehouse and then queried from R using the Snowflake ODBC driver. Notice that the same dplyr syntax used here will also work on an R data frame. The results from the query were then collected into R and visualized with ggplot2. For more information on using databases with R, see


con <- dbConnect(odbc::odbc(), "Snowflake")

tbl(con, "FLIGHTS") %>%
  filter(distance > 75) %>%
  group_by(origin, hour) %>%
  summarise(delay = mean(dep_delay, na.rm = TRUE)) %>%
  collect() %>%
  ggplot(aes(hour, delay, color = origin)) + geom_line()

Enhancements for Microsoft SQL Server and NTLM authentication

This release of the drivers includes an updated version of the SQL Server driver that supports environments using exclusively NTLM v2 authentication. Please refer to the documentation for the SQL Server driver in this release for additional details.

Fixed issues with MySQL commands

The previous release of the drivers introduced a regression for certain MySQL commands such as USE <database> and LOAD DATA INFILE. This new release restores that functionality.
