[GitHub] [shardingsphere] luojiang-killgrave commented on issue #7423: mysql keyword 'point'
luojiang-killgrave commented on issue #7423:
URL: https://github.com/apache/shardingsphere/issues/7423#issuecomment-691457594
Hello.
I am using shardingsphere-jdbc.
It's convenient and powerful. yet, I still got some problem.
Here is it:
My project got a sql like this: `select point from table_a where id = 1`
When program executes this sql.error happens.
Here is one of logs:`line 5:8 no viable alternative at input 'point,'`
I guess shardingsphere is dealing with 'point' as a mysql keyword.
So I change the sql to ``select `point` from table_a where id = 1``
It runs perfect.
But then i did some research, 'point' is not a mysql keyword.
So I keep wondering why shardingsphere treat it as a keyword?
Sorry for bothering!
Here is error log detail:
