Answer 1

Based on Alex answer i wrote this function to use rtrim in all variables.

query_nzz <- function(con, select="select * ", from="", where = "", limit = " 10000; "){
  options(scipen=666)

  # Get variable Names
  query_names = paste(select, " from ",from, where, sep = " ")
  names <- dbGetQuery(con, paste(query_names,"limit 1;", sep= " "))
  names <- names(names)

  # Trim spaces
  select <- paste0("trim(",names,") as ", names, collapse = ",")

  query = paste0("select ", select, " from ", from, where, " limit ",deparse(limit),";")
  data = dbGetQuery(con, query)
  data
}

Function usage

  dt <- query_nzz(
    con,
    select = "select * ",
    from = "DATABASE.TABLENAME",
    where = "",
    limit = 100000
  )
