SQL Tuning Advisor中的绑定日期

Question

我正在尝试使用Oracle SQL Developers SQL Tuning Advisor将日期绑定到变量，但是它将日期识别为VARCHAR2而不是DATE。有没有办法指定您绑定的参数的数据类型？

SQL：

SELECT * FROM Actv
WHERE ActvId = :in_UserGrpCds AND ActvTime >= :in_FromDate AND ActvTime < :in_ThruDate
OFFSET :in_CurrRecordOffset FETCH NEXT :in_NextRecordOffset ROWS ONLY;

in_ThruDate被绑定为VARCHAR2，它无法运行曲调。

Bind Variables :
 1 -  (NUMBER):1091
 2 -  (NUMBER):0
 3 -  (VARCHAR2):07-21-2018
 4 -  (NUMBER):50000
 5 -  (VARCHAR2):08-21-2018

Answer 1

我们仅绑定字符串/数字/空值，因此请调整您的SQL以包含to_date：

SELECT * FROM Actv
WHERE ActvId = :in_UserGrpCds 
AND ActvTime >= to_date(:in_FromDate ,'MM-DD-YYYY')
AND ActvTime < to_date(:in_ThruDate ,'MM-DD-YYYY')
OFFSET :in_CurrRecordOffset FETCH NEXT :in_NextRecordOffset ROWS ONLY;
