I tried this and doesn't work unforunately. I get "ERROR: Duplicate
entry..." that occurs when copying from the temporary table back into
the original table.
Is there a way to do this, to copy a single record, without moving the
primary key into the temporary table so I can avoid this error?

My client reported the a case to me. He said one mysql table lost some of
the data. The table structure is shown as follows:
+---+---+--+-+-+---+
| Field | Type | Null | Key | Default | Extra |
+---+-
What are the options to load data infile when not all lines in the file are
perfect.
For example, I have a 12 field file, but some of the data in the lines is
bad, could contain 10 or less, I just want to let those go in in the order
they are in.

The biggest problem I see is that you are using a text field and you don't
