Hi, one question. Do you put explicit "NULL" in the column value? Other option is. You have to delete the column "next_contact" in your INSERT clause. So, if the column has a default value, this value Will be inserted. Else Null value will be inserted.

Stay tuned to this mail list for test results. Dates are not treated as strings they are treated as dates. There is built casting for strings that are valid dates though: create table date_test(dt_fld date); insert into date_test values('01/11/19'); INSERT 0 1 --Trying MySQL 'null':) insert into date_test values('00/00/0000'); ERROR: date/time field value out of range: "00/00/0000" LINE 1: insert into date_test values('00/00/0000'); insert into date_test values(''); ERROR: invalid input syntax for type date: "" LINE 1: insert into date_test values(''); As pointed out you are being told '' is not a valid date. > > Thanks, > > Rich > > -- Adrian Klaver adrian.kla...@aklaver.com
