SIMPLE SQL选择查询位置

Question

Anyone got any idea why this doesn't work. Im at a loss

The following

SELECT * FROM  tblCustomerDetails WHERE AccountNo='STO00900'

Returns nothing however if i run the same query with any othe accoutn number it works.

and this account will show when i run

SELECT TOP 10 * FROM tblCustomerDetails ORDER BY ID desc

Picture explains it better.

Thanks

Answer 1

Try as Notulysses suggested, but I would recommend it a bit differently:

SELECT * FROM  tblCustomerDetails WHERE LTRIM(RTRIM(AccountNo)) = 'STO00900'

The LIKE operator will likely match more rows than you need (if te AccountNo column is not unique), so I'd go with trimming the whitespaces and then checking for a specific account.

Answer 2

条目的开头或结尾可能会有一些空间，请尝试修剪条目的两端。

Answer 3

Try

SELECT * FROM  tblCustomerDetails WHERE AccountNo LIKE '%STO00900%'

As there can be hidden characters.
