Sql Oracle | Varchar2 |数字相等|不同输出

我在Oracle中有一个表，比如说

表1

：

Column - ticketNo - NOT NULL VARCHAR2(10)

现在，当我运行不同的查询时，我会得到不同的输出，尽管记录是存在的

select * 
from Table1 
where ticketNo = '0900000106'; -- Fetches the record

select * 
from Table1 
where ticketNo = '0810087720'; -- Fetches the record

select * 
from Table1 
where ticketNo = '0050001104'; -- Fetches the record

select * 
from Table1 
where ticketNo = '3180000013'; -- Fetches the record


select * 
from Table1 
where ticketNo = '900000100'; --  Does not fetch the record

select * 
from Table1 
where ticketNo = '5889770';    -- Fetches the record

select * 
from Table1 
where ticketNo = 0900000106; -- Fetches the record

select * from Table1 where ticketNo = 0810087720; -- Fetches the record
select * from Table1 where ticketNo = 0050001104; -- Fetches the record
select * from Table1 where ticketNo = 3180000013; -- Fetches the record

select * from Table1 where ticketNo = 900000100; --  Fetches the record
select * from Table1 where ticketNo = 5889770;    -- Fetches the record

我无法理解为什么对少数记录的比较失败

我正在使用SQLDeveloper来查询上面的内容

Oracle IDE 17.4.1.054.0712

例如，当比较

ticketNo=900000106

时，ticketNo的字符值“090000106”被转换为数字900000106，并与正确的相等项匹配。

那么实际值是多少<代码>'0900000106'或

'900000106'

？很明显，这与

INT

conversion@HoneyBadger实际值为0900000100。此外，如果列是字符串，则带引号的版本是正确的。不管有没有吵架，那就很清楚了，不是吗<代码>900000106=900000106为真，

'0900000100'='900000100'

为真not@HoneyBadger是的，谢谢你指点
