获取jdbc允许用户使用的所有表

Question

I'm connecting to a database using jdbc, getting list of all schemas and tables from database (I assume that some databases may return at this point only tables which current user can query, but some of databases return full list of tables) and when user try to query some tables he get "insufficient privileges" error. Is there a way to get only tables, user can query using only jdbc capabilities? Without writing special query to database.

Now I'm looking at

      DatabaseMetaData dbMeta = connection.getMetaData() 
      dbMeta.getTablePrivileges(null, null, null);

But from result of this query it's not so clear which exactly tables can user query.

Currently I'm working with SAP HANA database, but in general it may be any database, so I'm looking for some common approach.

Please look at

http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#getTablePrivileges%28java.lang.String,%20java.lang.String,%20java.lang.String%29

You have to get the each row from the ResultSet and query of column name TABLE_NAME which contains the table name and PRIVILEGE which contains the access of each table.
