【问题描述】:
我是 MySQL 新手,但它的语法仍然存在问题。我有这个问题:
SELECT a, b, c, d, e
FROM table1
WHERE status = 'skipped'
AND batchid IN (SELECT batchid
FROM (SELECT distinct batchid, date_format(uploaddate, '%Y-%m-%d')
FROM table1
WHERE uploaddate > '2011-01-26') AS t
) AS t;
这给了我这个错误:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'as t' at line 1
IN 子句有效:
SELECT batchid
FROM (SELECT distinct batchid, date_format(uploaddate, '%Y-%m-%d')
FROM table1
WHERE uploaddate > '2011-01-26') AS t
我认为我的问题与第二个表别名有关。谁能告诉我我做错了什么?
