Description:
The actual mysqld-err.log is as follows.
bash

Thread pointer: 0x7fbbec183678
|
Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went
|
terribly wrong...

The actual query is as follows.
SELECT REQ_GRP_ID
|
FROM TB_REQ_MAIN
|
WHERE REQ_GRP_ID ='REQ_GRP_000000440'
|
ORDER BY ROW_NUMBER() OVER (ORDER BY CREATE_DTM) + 1;
|
The problem is ORDER BY ROW_NUMBER() OVER (ORDER BY RM.CREATE_DTM)`+1` part.
In the actual application, it occurs as follows
[2020-11-11 17:21:53] [08S01] Communications link failure
|
[2020-11-11 17:21:53] The last packet successfully received from the server was 149 milliseconds ago. The last packet sent successfully to the server was 149 milliseconds ago.
|
[2020-11-11 17:21:53] java.io.EOFException: Can not read response from server. Expected to read 4 bytes, read 0 bytes before connection was unexpectedly lost.
|
How to repeat:
SELECT REQ_GRP_ID
|
FROM TB_REQ_MAIN
|
WHERE REQ_GRP_ID ='REQ_GRP_000000440'
|
ORDER BY ROW_NUMBER() OVER (ORDER BY CREATE_DTM) + 1;
|
Suggested fix:
SELECT REQ_GRP_ID
FROM TB_REQ_MAIN
WHERE REQ_GRP_ID ='REQ_GRP_000000440'
ORDER BY ROW_NUMBER() OVER (ORDER BY CREATE_DTM);
