使用LEFT JOIN / IS NULL：
SELECT t.*
FROM TABLE_LIST t
LEFT JOIN TABLE_LOG tl ON tl.jid = t.jid
WHERE tl.jid IS NULL
使用NOT IN：
SELECT t.*
FROM TABLE_LIST t
WHERE t.jid NOT IN (SELECT tl.jid
FROM TABLE_LOG tl
GROUP BY tl.jid)
使用不存在：
SELECT t.*
FROM TABLE_LIST t
WHERE NOT EXISTS(SELECT NULL
FROM TABLE_LOG tl
WHERE tl.jid = t.jid)
LEFT JOIN / IS NULL和NOT IN在MysqL中是等效的-它们将执行相同的操作，而NOTEXISTS则较慢/效率较低。
