Daniel Dai commented on HIVE-17830:
-----------------------------------
Ok so "SET @@session.sql_mode=ANSI_QUOTES" will be required, right? Last time I
read the code, it seems prepareTxn will be invoked every time we created a new
ObjectStore. However, I must miss somewhere as otherwise, we will never hit the
sql syntax error.
> dbnotification fails to work with rdbms other than postgres

> as part of HIVE-17721 we had changed the direct sql to acquire the lock for
> postgres as
> {code}
> select "NEXT_EVENT_ID" from "NOTIFICATION_SEQUENCE" for update;
> {code}
> however this breaks other databases and we have to use different sql
> statements for different databases
> for postgres use
> {code}
> select "NEXT_EVENT_ID" from "NOTIFICATION_SEQUENCE" for update;
> {code}
> for SQLServer
> {code}
> select "NEXT_EVENT_ID" from "NOTIFICATION_SEQUENCE" with (updlock);
> {code}
> for other databases
> {code}
> select NEXT_EVENT_ID from NOTIFICATION_SEQUENCE for update;
