        (SELECT Name FROM NewsCategory 
         WHERE NewsCategoryId = N.HeadLineCategoryId) Category,
        N.PicUrl,
        N.Creation,
        SUBSTRING((fnStripTags(N.Description)),1,75) AS ShortDescription
FROM    News N
INNER JOIN
        (SELECT  HeadlineCategoryID, MAX(NewsID) max_id
         FROM    News           
         GROUP   BY HeadlineCategoryID) N_ 
   ON N.HeadlineCategoryID = N_.HeadlineCategoryID AND
      N.NewsID = N_.max_id
ORDER BY N.ViewIndex DESC  
LIMIT 6;  

Answer 1

Okay, Okay, just like this

SELECT  N.NewsId,
        N.HeadCaption,
        (SELECT Name FROM NewsCategory 
         WHERE NewsCategoryId = N.HeadLineCategoryId) Category,
        N.PicUrl,
        N.Creation,
        SUBSTRING((fnStripTags(N.Description)),1,75) AS ShortDescription
FROM    News N
INNER JOIN
        (SELECT  HeadlineCategoryID, MAX(NewsID) max_id
         FROM    News           
         GROUP   BY HeadlineCategoryID) N_ 
   ON N.HeadlineCategoryID = N_.HeadlineCategoryID AND
      N.NewsID = N_.max_id
ORDER BY N.ViewIndex DESC  
LIMIT 6 limit 6; 

at the end of code, with "limit 6" you get the next 6 rows from table/source

尝试使用SELECT DISTINCT而不是SELECT

Answer 3

Use the LIMIT function

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants, With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return.
