Question

我在table1中有一个名为text的字段。我怎么能算出有多少行有＆＃34; test＆＃34;，＆＃34; test2＆＃34;和＆＃34; test3＆＃34;？

到目前为止，我有：

SELECT count(*) FROM table WHERE text LIKE "%test%" OR text LIKE "%test2%" OR text LIKE "%test3%"

但只返回整个计数

我需要类似的东西：

test 100
test2 115
test3 12

有人能指出我正确的方向吗？

也许UNION会很适合你：

SELECT
    'test' AS `search_term`,
    COUNT(*) AS `term_count`
FROM table
WHERE text LIKE '%test%'
UNION
SELECT
    'test2' AS `search_term`,
    COUNT(*) AS `term_count`
FROM table
WHERE text LIKE '%test2%'
UNION
SELECT
    'test3' AS `search_term`,
    COUNT(*) AS `term_count`
FROM table
WHERE text LIKE '%test3%'
