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
