RMySQL dbWriteTable with field.types

Question

I have a data frame, called df, that looks like this:

dte, val
2012-01-01, 23.2323
2012-01-02, 34.343

The type on the columns

Answer 1

After playing with things, I realized what the problem is: field.types must be a NAMED list vector, not simply a list; additionally the row names must not be included otherwise we need three field types. For the above example, the following works fine:

dbWriteTable(con, name="table_name", value=df,
  field.types = c(dte="date", val="double(20,10)"), row.names=FALSE)
