原标题:Oracle SQR datediff, rounding off seconds, and type

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。

问题回答

姓名不详。 编号用编号序号表示(日期和位置有预设额)。

SQR具有(x, y)作为参数和回报(x)四舍五入到 y门的地点。
