Hello again, After 'googling', I set the environment variable MYSQL_HOME value to the path to MYSQL with the command below. I get a warning (is it a problem or not ???) but I managed to connect to my databases.
But when I close and open again R, the connection is lost. I have to run the command each time. Is there a way to definitively set the variable value ? Thank in advance, Have a nice week-end, Ptit Bleu. > Sys.setenv("MYSQL_HOME"="C:/MySQL/MySQL Server 5.1") > Sys.getenv('MYSQL_HOME') MYSQL_HOME "C:/MySQL/MySQL Server 5.1" > library(DBI) Warning message: le package 'DBI' a été compilé avec la version R 2.9.2 > library(RMySQL) Warning messages: 1: le package 'RMySQL' a été compilé avec la version R 2.9.2 2: In inDL(x, as.logical(local), as.logical(now), ...) : RMySQL was compiled with MySQL 5.0.67 but loading MySQL 5.1.44 instead! This may cause problems with your database connections. Please install MySQL 5.0.67. If you have already done so, you may need to set your environment variable MYSQL_HOME to the proper install directory. -- View this message in context: http://n4.nabble.com/Update-RMySQL-and-it-s-no-more-running-tp1561401p1561677.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
