上面显示的代码是程序。当我执行它 -

declare
return_val number;
BEGIN
pm_own.emav_input_check(TO_DATE('05/19/2014','MM/DD/YYYY'),TO_DATE('05/20/2014','MM/DD/YYYY'),return_val);
dbms_output.put_line(return_val);
END;

我收到以下错误：

Error report:

ORA-01858: a non-numeric character was found where a numeric was expected
ORA-06512: at "PM_OWN.EMAV_INPUT_CHECK", line 19
ORA-06512: at line 4
01858. 00000 -  "a non-numeric character was found where a numeric was expected"
*Cause:    The input data to be converted using a date format model was
           incorrect.  The input data did not contain a number where a number was
           required by the format model.
*Action:   Fix the input data or the date format model to make sure the
           elements match in number and type.  Then retry the operation.

知道如何修复此错误吗？

Answer 1

问题在于你如何使用INCOMING参数。这是你的代码：

SELECT COUNT (*) INTO bbg_yest
FROM Crd_Own.Bbg_Oiv v
WHERE asof_date = TO_DATE ('last_bus_day', 'mm/dd/yyyy');

'last_bus_day'是一个常量字符串。 Oracle尝试将mm（月份作为数字）从中取出并失败。

你的参数：last_bus_day IN DATE

因此您无需再进行任何转换：

SELECT COUNT (*) INTO bbg_yest
FROM Crd_Own.Bbg_Oiv v
WHERE asof_date = last_bus_day;

Answer 2

SELECT COUNT (*) INTO bbg_yest
FROM Crd_Own.Bbg_Oiv v
WHERE asof_date = TO_DATE ('last_bus_day', 'mm/dd/yyyy');

这些是不有效查询。 to_date函数需要一个表示日期的字符串，以及一个表示第一个参数是什么格式的格式字符串。 Last_bus_day与mm/dd/yyyy不匹配，因此失败。匹配字符串的示例是05/19/2014。

由于您的传入参数是日期，因此您应该将查询更改为：

SELECT COUNT (*) INTO bbg_yest
FROM Crd_Own.Bbg_Oiv v
WHERE asof_date = last_bus_day;

因为您不需要将字符串转换为日期，然后再转换为日期。

执行没有参数的oracle过程
