: 我的DATABASE里其中一个TABEL SET了一个PRIMARY KEY
: 入面我SET了
: REQUIRED是FALSE
: ALLOW ZERO LENGTH是TRUE
: INDEXED是TRUE和NO DUPLICATES
: 之后我用了RECORDSET UPDATE
: 但出了这句ERROR MESSAGE
: Index or primary key can't contain a Null Value
: 请问那里出错呢?是否DATABASE出错?????

无论 requided 设定为 false or true ,primary key 可以是一个空字串,但不能是 null,应该是如此吧!
