Připojení k databázi Oracle 10g přes R

Níže je uvedeno, co jsem udělal pro připojení R k databázi Oracle

1. Stáhněte si ovladač Oracle JDK http://www.oracle .com/technetwork/java/javase/downloads/index.html
2. Nainstalujte RJDBC

poté spusťte níže uvedený kód v r

library(RJDBC)
## Loading required package: DBI
## Loading required package: rJava
# specify the driver type and location in your machine

jdbcDriver = JDBC("oracle.jdbc.OracleDriver",
                  classPath="C:/app/techsupport/product/11.2.0/client_1/jdbc/lib/ojdbc6.jar") # may be different on your machine, it's based on your JDK installation

# connect to the database

conn = dbConnect(jdbcDriver, "jdbc:oracle:thin:@//database.hostname.com:port/service_name",  # get the database name, port, and service name from you DBA
             user = YourUserName,
             password = YourPassword)

# get office table using a query string

startTime <- Sys.time() # start timer
OfficeTable = dbGetQuery(conn, "select * from office")
# disconnect after working with database
dbDisconnect(conn)
## [1] TRUE
Sys.time() - startTime  # calc time to import table
## Time difference of 0.1630161 secs
# take a look at the data
str(OfficeTable)
## 'data.frame':    373 obs. of  22 variables:
