將if語句和多個sql查詢合並為一個查詢

Question

我有一台服務器，它限制了你每小時可以進行的 sql 查詢的數量，所以我試圖找到一種方法將我的所有 3 個 if 語句和 sql 查詢組合成一個 sql 查詢，我想知道這是否可能？ 請看一下我的代碼：

$text1 = "one";
$text2 = "two";
$text3 = "three";

$data = SELECT text FROM tableName WHERE 
text LIKE '%$text1%' AND
text LIKE '%$text2%' AND
text LIKE '%$text3%' order by rand() limit 1;

if ($data == null) {
$data = SELECT text FROM tableName WHERE 
text LIKE '%$text1%' AND
text LIKE '%$text2%' order by rand() limit 1;
}

if ($data == null) {
$data = SELECT text FROM tableName WHERE 
text LIKE '%$text1%' order by rand() limit 1;
}

Answer 1

SELECT text,
((text LIKE '%$text1%') + (text LIKE '%$text2%') + (text LIKE '%$text3%')) as `matches` 
FROM tableName 
HAVING `matches` > 0
ORDER BY `matches` DESC, rand() LIMIT 1

這應該按匹配數對值進行排序，因為每個表達式在匹配時將被視為整數 1，否則將被視為 0。
