无法显示在表格中的单词总数

Question

我在查找单词出现在整个表格中的总次数时遇到了麻烦。 我的代码目前只计算单词出现在每一行中的次数。我该如何解决这个问题？

SELECT comments, COUNT(*) AS total FROM AE
WHERE comments like '%'%' 
GROUP BY comments

如果您想要更多代码，请询问：）

Answer 1

你可以获得COUNT

SELECT  COUNT(*) AS total FROM AE
WHERE comments like '%abcd%' 

您只需使用WHERE

即可获得与该字词匹配的所有评论

SELECT  comments AS total FROM AE
WHERE comments like '%abcd%' 

如果您希望COUNT重复评论，则可以使用“CROSS APPLY”

select * from (SELECT  comments  
FROM AE
WHERE comments like '%abcd%' ) T
CROSS APPLY 
  ( SELECT  COUNT(*) AS total FROM AE
WHERE comments like '%abcd%' ) T2

Answer 2

这个数字是否足够？

SELECT COUNT(comments) AS total FROM AE
WHERE comments like '%'%'
