MySQL如何獲取每個關鍵字的行數

Question

我在table1中有一個名為text的字段。 我如何計算有多少行包含單詞“ test”，“ test2”和“ test3”？

到目前為止，我有：

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

但這只會返回全部計數

我需要類似的東西：

test 100
test2 115
test3 12

誰能指出我正確的方向？

也許UNION會很適合您：

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%'
