SQL查詢，通配符，MS SQL SERVER 2005

Question

我需要查詢拉的所有目錄名的東西有如下前綴「網站/測試/測試/」 是正確的語法「*」

SELECT DirName, count(*) AS FileCount, SUM(Size)/1024 as 'SizeKB' 
FROM alldocs 
Where DirName = 'site/test/test/*' 
GROUP BY dirName 
ORDER BY DirName 

Answer 1

你需要使用SQL的LIKE子句：

SELECT DirName, count(*) AS FileCount, SUM(Size)/1024 as 'SizeKB' 
FROM alldocs 
Where DirName LIKE 'site/test/test/%' 
GROUP BY dirName 
ORDER BY DirName 

你使用MySQL見http://www.sql-tutorial.net/SQL-LIKE.asp

Answer 2

？如果你是，你可以使用類似於的東西

 
SELECT DirName, count(*) AS FileCount, SUM(Size)/1024 as 'SizeKB' 
FROM alldocs 
Where LEFT(DirName, LENGTH('site/test/test/')) = 'site/test/test/' 
GROUP BY dirName 
ORDER BY DirName
