问题描述

我收到以下查询的 ORA:00936 错误.请告诉我查询中的问题

I'm getting ORA:00936 error for the following query.Please let me know the issue in the query

SELECT convert(DATE,r.created_dt) as created_dt,
r.created_dt as time,
r.rep_id,
rt.rep_type_id,
rt.rep_type_desc
FROM t_tbm_ia_rep_2015 r,
t_tbm_ia_rep_type_2015 rt
WHERE r.rep_type_id=rt.rep_type_id
GROUP BY r.created_dt,
r.rep_id,
rt.rep_type_id,
rt.rep_type_desc
ORDER BY rt.rep_type_id

推荐答案

SELECT convert(DATE,r.created_dt) as created_dt

SELECT convert(DATE,r.created_dt) as created_dt

问题在于CONVERT 函数的错误使用.请参阅文档.

The issue is with the incorrect use of CONVERT function. Please see the documentation.

SQL> SELECT convert(DATE,hiredate) as created_dt from emp;
SELECT convert(DATE,hiredate) as created_dt from emp
               *
ERROR at line 1:
ORA-00936: missing expression

我猜您正在尝试转换数据类型，您可以使用 TO_DATE 将字符串转换为日期.或者，TO_CHAR 反之亦然.

I guess you are trying convert the datatype, you could use TO_DATE to convert string into date. Or, TO_CHAR to do vice-versa.
