我想从一个字符串中的SQL删除空格,但LTRIM和RTRIM功能似乎并没有工作？

柱:

[ProductAlternateKey] [nvarchar](25) COLLATE Latin1_General_CS_AS NULL

查询:

select REPLACE(ProductAlternateKey, ' ', '@'),
       LEN(ProductAlternateKey),
       LTRIM(RTRIM(ProductAlternateKey))      AS LRTrim,
       LEN(LTRIM(RTRIM(ProductAlternateKey))) AS LRLen,
       ASCII(RIGHT(ProductAlternateKey, 1))   AS ASCIIR,
       ASCII(LEFT(ProductAlternateKey, 1))    AS ASCIIL,
       ProductAlternateKey
from DimProducts
where ProductAlternateKey  like '46783815%'

结果:

|  COLUMN_0 | COLUMN_1 | LRTrim | LRLen | ASCIIR | ASCIIL | PRODUCTALTERNATEKEY |
---------------------------------------------------------------------------------
