GetReaderbyfunc的示例数据

'544381428','544381436','544381433','544381424','544381043'

二,

三,

结果如下

'544381428','544381436','544381433','544381424','544381043'

因为nreaderidn是一个数字类型，但是当我像下面那样把它的结果放进去时，它就工作了

SELECT GETREADERSBYDESC('LOCKER') devices FROM dual

结果如下

'544381050','544381441','544381428','544381436','544381431','544381064','544381433','544381435','544381424','544381043'



WHERE 
  l.nreaderidn IN ( '544381428','544381436','544381433','544381424','544381043')

我不允许更改nreaderidn的数据类型和修改oracle函数。有办法解决这个问题吗？

提前感谢

您的函数返回一个逗号分隔的数字列表，需要拆分。试试看

例如：

您的查询将如下所示：

SELECT L.NEVENTLOGIDN, LPAD (nuserid, 6, '0') nuserid, u.susername, 
  TO_CHAR (TO_DATE ('1970-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS') + ( (ndatetime) / (60 * 60 * 24)), 'YYYY-MM-DD HH24:MI:SS') 
  date_time, l.nreaderidn, r.sname, 
  CASE WHEN l.nreaderidn IN (SELECT 
regexp_substr(GETREADERSBYFUNC('OUT', 'LOCKER'), '[^,]+', 1, level) FROM dual 
  connect by regexp_substr(GETREADERSBYFUNC('OUT', 'LOCKER'), '[^,]+', 1, level) is not null ) THEN 'O' 
  WHEN l.nreaderidn IN (SELECT 
   regexp_substr(GETREADERSBYFUNC('IN', 'LOCKER'), '[^,]+', 1, level) FROM dual 
  connect by  regexp_substr(GETREADERSBYFUNC('IN', 'LOCKER'), '[^,]+', 1, level) is not null) THEN 'I' END logtype 
  FROM TB_EVENT_LOG l, TB_READER r, TB_USER u 
  WHERE 
  l.nreaderidn IN ( SELECT 
   regexp_substr(GETREADERSBYFUNC('LOCKER'), '[^,]+', 1, level)  FROM dual 
  connect by  regexp_substr(GETREADERSBYFUNC('LOCKER'), '[^,]+', 1, level) is not null) 
  AND NDATETIME >= ((TO_DATE ('2020-01-27' || ' 12:00:00 AM', 'YYYY-MM-DD HH:MI:SS AM') ) - TO_DATE ('1970-01-01 12:00:00 AM', 'YYYY-MM-DD HH:MI:SS AM')) * 24 * 60 * 60 
  AND ndatetime <= ((TO_DATE ('2020-01-28' || ' 12:00:00 PM', 'YYYY-MM-DD HH:MI:SS PM') ) - TO_DATE ('1970-01-01 12:00:00 AM', 'YYYY-MM-DD HH:MI:SS AM')) * 24 * 60 * 60 
  AND l.nuserid = u.suserid 
  AND l.nreaderidn = r.nreaderidn 
  ORDER BY 2, 4

这不会给您一个错误：

SELECT * 
from TB_READER l
where cast(l.nreaderidn as varchar2(1024)) in (select GETREADERSBYDESC('LOCKER') devices FROM dual)

只需使用nreaderidn列的强制转换

但也要注意，您将在字符串中搜索一个varchar，例如“2”，而不是一系列字符，而是一个字符串“1”、“2”和“3”，因此不会返回任何结果

这里还有一个小示例，您可以看到在没有强制转换的情况下生成errir，并在添加强制转换时解决：

它告诉我现在缺少表达式您的函数返回什么？不确定上面的查询中为什么有设备。你能单独运行并告诉我结果吗？选择castGETREADERSBYFUNC'OUT'，LOCKER'as int FROM dual error表示SQL命令在尝试执行时未正确结束只需删除最后一个括号！！：从Dual中选择castGETREADERSBYFUNC'OUT'，LOCKER'作为int。Oracle中的日期减法是number，然后将它们与日期列进行比较。因此，问题似乎出现在这里，而nDatime>=截止日期'2020-01-27'| |'12:00:00 AM'，YYYY-MM-DD HH:MI:SS AM'-截止日期'1970-01-01 12:00:00 AM'，YYYY-MM-DD HH:MI:SS AM'*24*60*60和nDatime我认为这不是我在子查询运行的位置上赋值的原因。因此，日期减法不是逐行注释，然后告诉您在查询的哪一行触发错误的原因。并不是说已经有100行了。见上文1、2、3对不起，我更新了我的问题
