I have many table that I am saving to a MariaDb in AWS RDS. I can manually save the tables. However I want to create a loop to do and I can't figure out the syntax on the dbWriteTable command. library(RMySQL)
dbWriteTable(con, "Account" , Account, overwrite = T)
dbWriteTable(con, "Campaign", Campaign, overwrite = T)
dbWriteTable(con, "Contact" , Contact, overwrite = T)
dbWriteTable(con, "User", User, overwrite =T)
Instead I would like to do it in a loop.
nm = c("Account", "Campaign", "Contact", "User")
for (i in 1:length(nm)) {
dbWriteTable(con, nm[i], paste(nm[i]), overwrite = TRUE)
}
Per comments above, using get0
instead of paste
like so will work:
nm = c("Account", "Campaign", "Contact", "User")
for (i in 1:length(nm)) {
dbWriteTable(con, nm[i], get0(nm[i]), overwrite = TRUE)
}
Try this instead:
for (i in nm){
dbWriteTable(con, i, paste(i), overwrite = TRUE)
}
You do not need to extract the i from the original list with brackets, because i represents directly that object in the list. Essentially you are saying for each instance in nm, write to the db table named i (which will be one of the words in your list) and paste the value of i as the name.
