RODBC odbcDriverConnect() Connection Error

Question

I\'m trying to use

odbcDriverConnect(\'driver={SQL Server};server=servername\\instancename,port;database=testing;username=abc;password=123456\') 
         


        

Answer 1

1.Connet to MySQL

a)if Mysql is installed in your system, if not install it.

b)download the RMySQL IN R

library(RMySQL)

drv = dbDriver("MySQL 5.0.1")

make sure MySQL version is correct.

con = dbConnect(drv,host="localhost",dbname="test",user="root",pass="root")

use local host or use the server i.e ip address

use the required database name, user name and password

album = dbGetQuery(con,statement="select * from table")

run required query

close(con)

2.Another way to connect database

a)first install any database like MySQL,Oracle,SQL Server

b)install the ODBC connector for database

library(Rodbc)

channel <- odbcConnect("test", uid="ripley", pwd="secret")

test is the connection name of odbc conector which user has to set manualy

user can find this in Administrator tool

res <- sqlFetch(ch, "table name")

A table can be retrieved as a data frame

res<-sqlQuery(channel, paste("select query"))

part of the with condition one table can be retrieved as a data frame

sqlSave(channel, dataframe)

to save a dataframe to the database(dont use "res<-" something like this)

like user can use

sqlCopy() sqlDrop()

sqlTables()

close(channel)

always close the connection
