Please excuse: "dbWriteTable" functions are mentioned in the
documentation for packages RMySQL, RSQLite, ROracle, DBI, RJDBC, RpgSQL,
RH2, sqldf, and RSQLite.extfuns, at least according to the following:
install.packages('sos') # if it's not already installed
library(sos)
(dbw <- ???dbWriteTable)
This found 38 help pages in 10 packages matching "dbWriteTable".
If you had provided "sessionInfo()", we'd at least know which one of
these you were trying to use.
Have you tried something like the following:
x2010 <- read.table('2010101000.txt')
dbWriteTable(con, "b20101010", x2010, overwrite = T)
If this does not work, please note that there is a mailing list
specifically for questions regarding database issues with R (R-SIG-DB:
"https://stat.ethz.ch/mailman/listinfo/r-sig-db";).
Hope this helps,
Spencer Graves

something like CHARACTER or NUMERIC... maybe.

Dear Rusers,
I am trying to feed my database with data from a file.
But since my file (2010101000.txt) there`s no headers I am facing problem
because the
result data.frame is not separated my columns.
How could I set variables names for each columns in *dbWriteTable*? I have
tried the command below but I don`t know how to fill the *field.type*option.
dbWriteTable(con, "b20101010", "./2010101000.txt", overwrite = T, sep =
"\t",row.names=c("V01", "V02", "V03", "V04", "V05", "V06"," V07","V08",
"V09", "V10", "V11", "V12", "V13", "V14"),field.type=????)
===Below what I have been used. I need to know how to set the column names
to xx (my dataframe).
drv=dbDriver("MySQL")
con<- dbConnect(drv,dbname='buoy',user="xx",password="xxx")
dbWriteTable(con, "b20101010", "./2010101000.txt", overwrite = T, sep =
"\t", head = F)
[1] TRUE
*xx*<- dbGetQuery(con, "SELECT * FROM b20101010 ")
xx
* V1
