jdbc information from ngdbc.jar

Hi all.

I wants to know about jdbc client info API.

I have to use different query as jdbc version.

For example

if Client version is 39 and then execute Another query that right for Revision 39.

if Cient version is 51 and then execute Another query that right for Revision 51.

I think con.getMetaData() is not enough.

do you have any idea about this?

please give me advice.

thanks.
