sql语句转换成033或001 以下是详细分析： 1、select power(10,3)得到1000 2、select cast(1000+33 as varchar）将1000转换类型 3、select right(100033,3) 从右边取3个字符得到033 将1格式化同上 select right(cast(power(10,3) as varchar)+33,3)

--用法例子
CREATE TABLE #T
(
    val NVARCHAR(50) NOT NULL
)

INSERT INTO #t
SELECT ‘35040112‘ UNION    ALL
SELECT ‘35040112‘ UNION    ALL
SELECT ‘35040112‘ UNION    ALL
SELECT ‘35040102‘ UNION    ALL    
SELECT ‘35040102‘ UNION    ALL    
SELECT ‘35040102‘ UNION    ALL    
SELECT ‘35040102‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘ UNION    ALL    
SELECT ‘35040105‘

SELECT val AS 查出的料号,val +‘-‘+ right(cast(power(10,2) as varchar)
       +CAST(ROW_NUMBER() OVER (PARTITION BY val ORDER BY val) AS NVARCHAR),2) AS 需变成的这种 FROM #T
