>Thanks for this, but how do I set a value to null? I thought null and '' >were the same, but now I see it is not. '' means that "the value is an empty string" whereas null means there is no value/the value is unknown/the value is not determined yet. You can "fix" all your dates by doing an: update <table> set <datefield> = <contentfunction>(julianday(<datefield)); where <contentfunction> is one of date time or datetime depending on whether the <datefield> is supposed to contain a date, time, or datetime respectively. The date will be normalized but the result will be null if the field is blank or contains a time outside the 00:00:00 - 23:59:59 valid time strings. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
