Question

我想生成包含默认字符和4位数字的唯一字符串。

例如-

"AKL0001"
"AKL0002"
"AKL0010"

像这样

Answer 1

尝试这样

WITH cte AS 
( SELECT 1 AS Num
  UNION ALL
  SELECT Num + 1
  FROM cte
  WHERE Num < 10000
 )
 SELECT 'AKL'+RIGHT(CONCAT('0000',Num),4)
 FROM cte

Answer 2

尝试一下。您可以根据需要更改选项：

DECLARE @min bigint, @max bigint, @string VARCHAR(12)
SELECT @Min=1 ,@Max=1000, @string = 'AKL'

SELECT TOP (@Max-@Min+1) @string + RIGHT(@Min-1+row_number() over(order by t1.number) + 1000 * @max, 4) as N
FROM master..spt_values t1 
CROSS JOIN master..spt_values t2
