scope of a local temporary table in HANA through jdbc

Jan 31, 2017 at 11:04 AM | 119 Views

hi all

In my HCP Java web app, I need to call PreparedStatements through jdbc to execute SQL calls that involve local temporary tables in HANA. I need to make sure that these temporary tables are not shared across multiple requests done by application's http clients.

What I know is that local temp tables are specific per session. I am not sure if there is a 1:1 mapping between a java.sql.Connection and a HANA session. I'd assume that if I can make sure that each client request is served by a different Connection, then the HANA sessions will be different and local temp tables will not generate interference.

Can anyone confirm?

Thanks

Vincenzo

    Hello Vincenzo,

    You are right. The local tables are session specific and the table metadata is itself is not available to another session.
