，我需要的是結果：

10914 
10921 
10918 
10923 
10922 
10913 
10912 
10907 
10915 
... 
...

怎麼會變成這樣select語句看？

select column from table where column...

總是4位數？你想整個專欄，還是隻搜索它？ – gbn 2010-11-05 17:14:26

@gbn我很抱歉我更新了這個問題。它並不總是四位數字。我只是想從列 – 2010-11-05 17:16:26

這一列返回這些值，但我不清楚你想要做什麼 - 從列中檢索所有數字數據，檢索文件名的前五個字符（不包括文件路徑），在每一行隨機生成一個五位數的數字......請你可以澄清你試圖達到的目標。 – 2010-11-05 17:28:30

它分解爲兩個步驟：

  1. 放棄一切高達數開始（在這裏我假設3個digists最小）
  2. 然後採取一切高達下一個非數字位數

你所需要的留下了情況的數量是在年底，因爲PATINDEX將返回零

DECLARE @MyTable TABLE (bigstring varchar(200)) 
INSERT @MyTable VALUES ('F:\MassHunter\DATA\6897_Pan_1\QuantResults\6897_Pan_1.batch.bin') 
INSERT @MyTable VALUES ('F:\MassHunter\DATA\6897_Pan_1\QuantResults\6897_Pan_1.batch.bin') 
INSERT @MyTable VALUES ('10914_Excel Short Summary.xls') 

SELECT --assumes number not at end of string 
    LEFT(startOf, PATINDEX('%[^0-9]%', startof)-1) 
FROM 
    (
    SELECT --assumed 3 digits minimum 
     SUBSTRING(bigstring, PATINDEX('%[0-9][0-9][0-9]%', bigstring), 8000) AS startOf 
    FROM 
     @MyTable 
    ) foo

@JNK：謝謝。我可以評論一下你使用「他」的用戶名爲「我是女孩」:-) – gbn 2010-11-05 17:31:41

@gbn - 只是抓住並修復它，因爲你輸入:) – JNK 2010-11-05 17:32:05
