Question

我正在尝试这样做

startdate = "20160123"
enddate = "20160204"
cmd = "select identification_number from bug where submitted_date >= TO_DATE(:1,'dd-MON-yy') and submitted_date <= TO_DATE(:2,'dd-MON-yy')"
cursor.execute(cmd,(startdate,enddate))

我收到错误

cursor.execute(cmd,(sdate,edate))
cx_Oracle.DatabaseError: ORA-01861: literal does not match format string

我看到了有关此错误的先前线程，但没有解决我的问题

我不确定startdate和enddate如何转换为:1和:2，但如果确实如此，则问题是日期格式问题。您正在传递YYYYMMDD并将其转换为DD-MON-YYYY。尝试改变它。你也缺少from条款。

我改为使用between子句。

select identification_number 
from <your_table>
where 
submitted_date between 
TO_DATE(:1,'YYYYMMDD') and TO_DATE(:2,'YYYYMMDD')

如果可行，请在代码中使用相同的日期格式

startdate = "20160123"
enddate = "20160204"
cmd = "select identification_number from <your_table> where submitted_date between TO_DATE(:1,'YYYYMMDD') and TO_DATE(:2,'YYYYMMDD')"

Cx_oracle：在python中使用变量To_date
