SQL_自定義排序

解決方案

用"按字段排序" (ORDER BY FIELD).

語法

ORDER BY FIELD(id, 5, 3, 7, 1)

要注意的是, FIELD 後面是沒有空格的.
因此, 完整的 SQL 爲:

SELECT * FROM MyTable
WHERE id IN (1, 7, 3, 5)
ORDER BY FIELD(id, 5, 3, 7, 1)

常見應用

SELECT * FROM MyTable
WHERE name IN (‘張三’, ‘李四’, ‘王五’, ‘孫六’)
ORDER BY FIELD(name, ‘李四’, ‘孫六’, ‘張三’, ‘王五’)
