如何根据该单词组的另一列中的每个单独单词和总和值进行分组？

Question

比方说，我有一个表，像这样的数据：

keyword   times_phrase_searched 
-------   --------------------- 
open windows  1000 
closed windows 750 
open doors  350 
closed doors  250 
nice window  100 
nice windows  50 
ugly doors  25 

我会分别需要什么SQL查询，以便组中的每个字，总结这个词出现在短语的搜索量因此，对。示例数据，预期结果将是：

word    times_word_in_searches 
----    ---------------------- 
windows   1800 
open    1350 
closed   1000 
doors   625 
nice    150 
window   100 
ugly    25 

Answer 1

如果你没有一个数字表，创建一个（见如何here）。然后你可以使用这个查询来获取字数：

select SUBSTRING_INDEX(SUBSTRING_INDEX(words.keyword, ' ', numbers.n), ' ', -1) word, 
     SUM(words.times_phrase_searched) times_word_in_searches 
from numbers 
inner join words on CHAR_LENGTH(words.keyword) - CHAR_LENGTH(REPLACE(words.keyword, ' ', '')) >= numbers.n - 1 
group by word 
order by sum(words.times_phrase_searched) desc; 

这将您的关键字列，让你对自己行的每个单独的关键字。那么对于group和sum这是一件简单的事情。

;

with tmp(keyword, times_phrase_searched) as(
select times_phrase_searched, LEFT((keyword, CHARINDEX(' ',(keyword+' ')-1), 
STUFF(Data, 1, CHARINDEX(' ',keyword+' '), '') 
from TestData 
Union ALL 
select times_phrase_searched, LEFT((keyword, CHARINDEX(' ',(keyword+' ')-1), 
STUFF(Data, 1, CHARINDEX(' ',keyword+' '), '') 
from Test 
Where Data >'') 
SELECT 
    keyword, 
    SUM(times_phrase_searched) AS times_phrase_searched 
FROM tmp 
GROUP BY keyword;

尝试......

DECLARE @temp TABLE 
    ( 
    keyword VARCHAR(max), 
    times INT 
) 

INSERT INTO @temp 
VALUES  ('open windows', 
      1000), 
      ('closed windows', 
      750), 
      ('open doors', 
      350), 
      ('closed doors', 
      250), 
      ('nice window', 
      100), 
      ('nice windows', 
      50), 
      ('ugly doors', 
      25) 

DECLARE @allValues VARCHAR(max) = (SELECT Stuff((SELECT 
              ',' + Replace(p2.keyword, ' ', 
              ',') 
       FROM @temp p2 
       ORDER BY p2.keyword 
       FOR xml path(''), type).value('.', 'varchar(max)'), 1, 1, '')) 


-- find distinct words 
SELECT DISTINCT t.element, 
       (SELECT Sum(k.times) 
       FROM @temp k 
       WHERE k.keyword LIKE '%' + t.element + '%') 
FROM dbo.Func_split(@allValues, ',') t
