in Oracle SQR (please, I know how already in SQL, I m asking about SQR syntax), how can I:
- determine the "type" of a variable? I can t find any "type" function
- what is the data type returned by datediff()?
- and finally, how do I round off to whole seconds the amount returned by
datediff($date1, $date2, MINUTE )
?
提前感谢。 寻求这一点是一个问题,因为我拿回了库克语的吨位,结果产生了真正的功能。
