I'm trying to insert rows into a table, but some date and time columns are missing values. In the INSERT INTO ... statements of the .sql file I've tried various formats: ,, and ,'', and ,' ', but they all generate the error of invalid syntax for type date. When I have missing date of the date and time types, how do I validly represent them in the input file?
