无效号码，如果没有无效号码

Question

Oracle抛出错误时有问题

  

ORA-01722：无效的号码   01722. 00000-“无效编号”   *原因：指定的号码无效。   *操作：指定一个有效的数字。

除已排除的一些异常情况外，所有位置均遵循相同的规则。

下面是示例输出：

A列：该行必须小于39

B列：身高必须小于17

Location_23_23是小岛

某些位置的设计不同，因此我在位置6处添加了“-”检查以消除这些错误。例如（C0S1-0101）

ive已导出数据，未发现异常，但是在结果中滚动时会出现错误。

下面的代码：

select location_id,to_number(ltrim(rtrim(substr(location_id,7,2)))) asa,to_number(ltrim(rtrim(substr(location_id,9,2)))) as b,to_number(ltrim(rtrim(substr(location_id,4,2)))) as Location_23_23
from location 
where location_id like '%C0S%'
and location_id not in ('C0SKRUSAGE','C0SKYUSAGE','C0SRBUSAGE') 
and to_number(ltrim(rtrim(substr(location_id,7,2)))) < 39  
and current_volume = 0  
and to_number(ltrim(rtrim(substr(location_id,9,2)))) < 17
and to_number(ltrim(rtrim(substr(location_id,4,2)))) between 23 and 23
and substr(location_id,6,1) = '-'

这玩了几个小时后终于解决了我的问题！

select location_id as Location_id
from location 
where location_id like '%C0S%'
and location_id not in ('C0SKRUSAGE','C0SKYUSAGE','C0SRBUSAGE') 
and ltrim(rtrim(substr(location_id,7,2))) < '48' 
and current_volume = 0 
and ltrim(rtrim(substr(location_id,9,2))) < '15'
and ltrim(rtrim(substr(location_id,4,2))) between '65' and '86'
and substr(location_id,6,1) = '-'

删除TO_NUMBER并在数字周围添加“＃”！
