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.
