JPA 中的 @Query 为 STR TO DATE 提供空输出

Question

the following query is resulting in null output for all the entries in the resulting list.

 @Query(value="select STR_TO_DATE(sp.date,'%d-%m-%Y') from shift_plan sp where sp.date>=:leaveDate and sp.shift_type NOT IN('leaveMorning','leaveAfternoon')",nativeQuery=true)
    public List<Date> findDatesGreaterThanOrEqualToLeaveDate(@Param("leaveDate") Date leaveDate);

I have saved the date as Date type in my java code but it has been saved as varchar in my database table shift_plan.I have saved from java as follows

cal.setTime(sdf.parse(j + "/" + (month_num + 1) + "/" + year));
                        sp.setDate(cal.getTime());

How to get the list of actual dates here?

Answer 1

This issue got fixed after changing the datatype of date from varchar to date in database. STR_TO_DATE was not required after that.
