User-Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:47.0) Gecko/20100101 Firefox/47.0
Build Identifier:

When you COPY INTO from a CSV file, using mclient, and the parsing of a certain field fails, you get a message saying something like:

"Failed to import table line 1 field 13 'smallint' expected in '1247801'"

This could be improved in more than one way, but the most significant drawback is the lack of a column name. At this point, clearly the server knows/can know which column the value should go into (otherwise it would not know the type); it would be very helpful for the user to print the column name as well as the index (especially since it's not trivial to determine whether the field index is 1-based or 0-based), and columns in MonetDB are not typically identified using indices.

Reproducible: Always

This has nothing to do with the client.

Please don't add my name to the cc list. I get the notifications by other means already.

Sorry for not making this comment earlier, but - why not print both?
