[GitHub] [shardingsphere] myfairys opened a new issue #15613: About select column num is not match result column ,and always less one.
myfairys opened a new issue #15613:
URL: https://github.com/apache/shardingsphere/issues/15613
it's version:4.1.0
i use ShardingSphere-Proxy.
when i use the sub query on select column, i can't get the correct result. i always get a result that the result column numbers is less one than select column. For example：
i use this sql:
`SELECT
im.id AS id,
im.inquiry_code AS inquiryCode,
im.visitor_id AS visitorId,
im.content AS content,
im.chat_box_mark AS chatBoxMark,
im.access_user AS accessUser,
im.STATUS AS STATUS,
im.create_time AS createTime,
im.update_time AS updateTime,
im.top AS top,
im.deleted AS deleted,
im.user_type AS userType,
b.content AS lastMessage
,(
SELECT
count(*) AS msg
FROM
leshan_visitor_record
WHERE
is_read = 0
AND im.inquiry_code = inquiry_code
GROUP BY
inquiry_code
) as msgcount,
b.create_time AS lastRecordTime,
'aaa' as aaa
FROM
im_inquiry im
LEFT JOIN ( SELECT * FROM ( SELECT * FROM `leshan_visitor_record` ORDER BY create_time DESC LIMIT 10000 ) a GROUP BY a.inquiry_code ) b ON im.inquiry_code = b.inquiry_code`.
**i can get result but don't have "aaa",and is that i use sub query on select column???**
such as :
`1 ZX202202231057001 12345 测试 GROUP-431401804259393537 5 0 2022-02-23 10:57:15 2022-02-23 10:57:15 0 0 0 测试 1 2022-02-23 10:57:15
2 ZX202202231058001 123456 测试1 0 2022-02-23 10:58:49 2022-02-23 10:58:49 0 0 0 测试 2 2022-02-24 10:58:49`
and i don't know why happen.
Can you tell me how to resolve this bug? Thanks.
