Write a data frame to Oracle Data Base

Hi guys:



When I use the ROracle package, I found the function 'dbWriteTable'
can't work.

The data frame can't be written to 10g Oracle Data Base. Here is what
happened to me.

library(DBI)
library(ROracle)
drv <- Oracle()
con <- dbConnect(drv , 'uid','pw','db')
mm <- data.frame(CO2)
dbWriteTable(con,'eve_tmp',mm)

Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "dbPrepareStatement",
for signature "OraConnection", "character", "list"
[1] FALSE

And I tried the RODBC package, 'write' function is OK.
Is it the Oracle version' problem? : (


Best regards
