【问题描述】：
我在从 SP 的日期字段中检索时间时遇到问题。如果我运行查询：
select TO_CHAR(HOR_HST_ATN,'YYYY/MM/DD HH24:MI:SS') AS HOR_HST_ATN FROM AAM0_DT_RSTCN ;
返回日期和时间ok。
但在SP中，代码：
SELECT FEC_DSD_ATN, FEC_HST_ATN, NOM_SEM_DSD_ATN, NOM_SEM_HST_ATN,
TO_DATE(HOR_DSD_ATN ,'DD/MM/YYYY HH24:MI:SS') as HOR_DSD_ATN,
TO_DATE(HOR_HST_ATN,'DD/MM/YYYY HH24:MI:SS') as HOR_HST_ATN
只返回日期 ok 但时间是 00:00
如果我尝试在 SP 中使用 TO_CHAR 进行选择，如下所示：
SELECT FEC_DSD_ATN, FEC_HST_ATN, NOM_SEM_DSD_ATN, NOM_SEM_HST_ATN,
TO_CHAR(HOR_DSD_ATN ,'YYYY/MM/DD HH24:MI:SS') as HOR_DSD_ATN,
TO_CHAR(HOR_HST_ATN,'YYYY/MM/DD HH24:MI:SS') as HOR_HST_ATN
我收到错误：SQLCODE: -6502 SQLERRM: ORA-06502: PL/SQL: error ...
有什么线索吗？顺便说一句，我必须使用 SP 来检索此值。
更新：该列是日期类型。这是完整的 SP：

【问题讨论】：
-
“ORA-06502：PL/SQL：数字或值错误。您尝试执行导致算术、数字、字符串、转换或约束错误的语句。”存在不具有预期类型的列或变量。我们能看到完整的代码吗？
-
什么是存储过程代码。该列是 DATE 还是 TIMESTAMP ？
