postgresql - How to get the local port of a jdbc connection? -

-

As far as I know that more than one connection objects through JDBC If the database is installed in the database, then each connection places a separate port on the machine where connection is installed (they all connect to a port on the server, where DBMS is running).

I tried to remove the port. Connection corresponds to the objects. Unfortunately I have not found any way to do this.

Background: I am doing performance analysis where I establish several clients who issue questions on DB. I am logging the execution time of the query on the database server. I have the resultant log - between others - information about connections, who started the query, e.g. localhost.localdomain: 44760 I hope that this information can be used to map the customer to each query or for a more accurate connection object, (Which is my final goal and works in the analysis objectives).

Simply select through this JDBC connection: 

  inet_client_port () Select

in more ways like this:

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
