If an input line has too few fields, the table columns for which input fields are missing are set to their
default values. Default value assignment is described in
An empty field value is interpreted different from a missing field:
• For string types, the column is set to the empty string.
• For numeric types, the column is set to 0.
• For date and time types, the column is set to the appropriate "zero" value for the type. See
Section 11.1.5, "Date and Time
These are the same values that result if you assign an empty string explicitly to a string, numeric, or
date or time type explicitly in an
