Hello,

I would like to retrieve data stored in MySQL database, so I installed
RMySQL package.
I can successfully connect with the my database using the following code

> dvr<-dbDriver("MySQL")
> con2<-dbConnect(dvr,group="exbardiv")
> mysqlDescribeConnection(con2)

<MySQLConnection:(972,0)> 
  User: mmorag 
  Host: localhost 
  Dbname: exbardiv 
  Connection type: localhost via TCP/IP 
  No resultSet available

I can even see the tables in the database

> dbListTables(con2)
[1] "agoueb"    "high_ld"   "rescue"    "sjlc_info" "sjlc_ld"   "temp"

[7] "temp_snp1" "temp_snp2"

However, when I try to query the database, R breakes.

res<-dbSendQuery(con,'select * from sjlc_ld')

Can anyone help me tune up the connection between R and MySQL?

Thank you,
Marc.
