"CSV does not work with NULL value in datetime fields"
Attempting to insert a row with a NULL value for a DATETIME field
results in a CSV file which the storage engine cannot read.
Don't blindly assume that "0" is acceptable for all field types,
Since CSV does not support NULL, we find out from the field the
default non-null value.
Do not permit the creation of a table with a nullable columns.
