Question

问题是COLA填充了0s

我要做的是用COLA验证COLB，COLC，COLD，COLE，COLF

或者我以错误的方式解决了这个问题！

如何使用COLB，COLD将Number（int）与填充数字子字符串进行比较？

实施例这是正确的

COLB    COLC    COLD    COLE    COLF               COLA

1        DD      5       1       0                     should = 01DD000510

不是这些中的任何一个

COLB   COLC   COLD  COLE   COLF    COLA

50     AA     230   2       0        0
50     AC     600   3       0
50     AG     740   2       0        50AE074020
50     AS     240   3       0        *0AS024030

 -- select that does not work statement.

 SELECT COLA ,
        COLB ,
        SUBSTRING(COLA, 1, 2) AS 'BLC_COLB' ,
        COLC ,
        SUBSTRING(COLA, 3, 2) AS 'BLC_COLC' ,
        COLD ,
        SUBSTRING(COLA, 5, 4) AS 'BLC_COLD' ,

        SUBSTRING(COLA, 9, 1) AS 'BLC_COLE' ,

Answer 1

执行此操作以选择＆＃34;未经验证的所有行＆＃34;：

SELECT  *
FROM    ATABLE
WHERE   RIGHT('0' + CAST(COLB AS VARCHAR), 2) +
        COLC +
        RIGHT('000' + CAST(COLD AS VARCHAR), 4) +
        COLE +
        CAST(COLF AS VARCHAR) <> COLA

Answer 2

在进行比较之前，将零填充数转换为整数。

CASE
   WHEN ZeroPadded NOT LIKE '%[^0-9]%'
   THEN CAST(ZeroPadded AS int)
END

T-SQL将数字与填充数字子字符串进行比较
