我厌倦的解决方案无效。任何人都可以提供解决方案。



我尝试过：

The Solution which i have tired was not working . Can any one please provide the solution.

What I have tried:

Declare  @Sorting TABLE(BusinessName varchar(50) NULL)
Declare @sortOrder  varchar(10) = 'ASC'  -- DESC

INSERT INTO @Sorting (BusinessName) VALUES ('ABCD')
INSERT INTO @Sorting (BusinessName) VALUES ('Zeebra')
INSERT INTO @Sorting (BusinessName) VALUES ('& ABCD')
INSERT INTO @Sorting (BusinessName) VALUES ('2 DEF')
INSERT INTO @Sorting (BusinessName) VALUES ('Hello &')
INSERT INTO @Sorting (BusinessName) VALUES ('1 Elephant &')


If(@sortOrder='ASC')
BEGIN
SELECT * FROM @Sorting ORDER BY  
			   CASE 
               WHEN PATINDEX('[0-9]%', BusinessName)=1
                 THEN LEFT(BusinessName,PATINDEX('[0-9]%',BusinessName)) 
               End asc,
			   case when PATINDEX('[^0-9a-zA-Z]%', BusinessName)=1
			   Then LEFT(BusinessName,PATINDEX('[^0-9a-zA-Z]%',BusinessName))	
			   end asc, BusinessName asc 		   
END
else 
BEGIN
SELECT * FROM @Sorting ORDER BY BusinessName desc 	,

			   case when PATINDEX('[^0-9a-zA-Z]%', BusinessName)=1
			   Then LEFT(BusinessName,PATINDEX('[^0-9a-zA-Z]%',BusinessName))	
			   end desc, 	
			   
			    CASE 
               WHEN PATINDEX('[0-9]%', BusinessName)=1
                 THEN LEFT(BusinessName,PATINDEX('[0-9]%',BusinessName)) 
               End desc
end

推荐答案

您的案例陈述已被清除。这将有效：

Your case statements are hosed up. This will work:

If @sortOrder LIKE 'ASC%'
BEGIN
    SELECT * FROM @Sorting 
    ORDER BY CASE WHEN PATINDEX('[0-9]%', BusinessName)=1
                  THEN LEFT(BusinessName,PATINDEX('[0-9]%',BusinessName))
                  ELSE CASE WHEN PATINDEX('[^0-9a-zA-Z]%', BusinessName)=1
                            THEN LEFT(BusinessName,PATINDEX('[^0-9a-zA-Z]%',BusinessName))	
                            ELSE BusinessName 
                       END
             END ASC;
END
ELSE
BEGIN
    SELECT * FROM @Sorting 
    ORDER BY CASE WHEN PATINDEX('[0-9]%', BusinessName)=1
                  THEN LEFT(BusinessName,PATINDEX('[0-9]%',BusinessName))
                  ELSE CASE WHEN PATINDEX('[^0-9a-zA-Z]%', BusinessName)=1
                       THEN LEFT(BusinessName,PATINDEX('[^0-9a-zA-Z]%',BusinessName))	
                       ELSE BusinessName 
                       END
             END DESC;
END
