我正在试图写入一个使用多个关键字搜索的选定语句。 例如,
SELECT id FROM my_mod mm WHERE (mm.name LIKE %joe% OR mm.name LIKE %jim% );
我想做的是 返回数据有一个额外的列 计数该行的次数 与类似语句的次数。
如果上面有一个名称 < code>jimjoe , 它会计2, 或者如果这个名称是 jim
, 它会计1。 有人知道这样做的方法吗?
我还要提到,我无法使用临时表格。

试试这个
select t.id,count(*) FROM
((select id from my_mod where name like %jim% )
union all
(select id from my_mod where name like %joe% )) t group by t.
"http://sqlfiddle.com/#!2/a654d7/3" rel="no follow" >我在这里检查它是如何工作的
SELECT id,
CASE
WHEN mm.name LIKE %joe%
AND mm.name LIKE %jim% THEN 2
ELSE 1
end AS cnt
FROM my_mod mm
WHERE mm.name LIKE %joe%
OR mm.name LIKE %jim%
尝试此查询 -
SELECT
COUNT(IF(name LIKE %joe% , 1, NULL)) joe_count,
COUNT(IF(name LIKE %jim% , 1, NULL)) jim_count
FROM
my_mod
WHERE
name LIKE %joe% OR name LIKE %jim%
