Hello, How can I make sqlSave only to write a subset of columns. I've a (MS-Access) table with columns A, B, C en D and if I send a sqlSave command with a data frame with columns A, B en D I get the message: Error in odbcUpdate(channel, query, mydata, coldata[m, ], test = test, : missing columns in 'data' Calls: sqlSave -> sqlwrite -> odbcUpdate (The columns in my table are all defined optional) I can add a dummy column to my data frame with name C and value NA and sqlSave will be happy, but is there another way to do this? Arguments to sqlSave? I can't find them in the documentation.
