[GitHub] [shardingsphere] nkuflk opened a new issue #6228: mysql alias table not work when I upgrade from 4.0.0 to 4.0.1
nkuflk opened a new issue #6228:
URL: https://github.com/apache/shardingsphere/issues/6228
I have a SQL
`
SELECT min(id) AS min_id, max(id) AS max_id
from (
select id
FROM msg
WHERE id > #{minId}
AND date = #{date}
ORDER BY id
limit #{step}
) a
`
In version 4.0.0, the actual in log is
`
SELECT min(id) AS min_id, max(id) AS max_id
from (
select id
FROM msg_10
WHERE id > ?
AND date = ?
ORDER BY id
limit ?
) a ::: [-1, 2019-04-26 00:00:00.0, 1]
`
But when I upgrade to 4.0.1, the actual sql in log is
`
SELECT min(id) AS min_id, max(id) AS max_id
from (
select id
FROM msg
WHERE id > ?
AND date = ?
ORDER BY id
limit ?
) a ::: [-1, 2019-04-26 00:00:00.0, 1]
`

I hope to use 4.1.1 because it has long sql optimize. But 4.1.1 still not work for alias table.

4.1.1 also has this problem. I have tried 4.0.0, 4.0.1, 4.1.0, 4.1.1, only 4.0.0 is ok.
I review the SQLParseEngine in shardingsphere-sql-parser, it has a big upgrade in 4.0.1, maybe the upgrade has some problem.
