how pass SQLTypeAdapters to create a SQLQueryParms(supplementary explanation)?

[Alex Luya]

In fact,I need to pass variables to template query(counts changed 
dynamically),so make a  test to try to run following code,but got an 
exception:Not enough parameters to fill the template.So can any guys 
point out the issues for me?Thank you.

try {
               Query query = serverConn.query("INSERT INTO sync_status 
VALUES(%0q,%1,%2q)");
               query.parse();

               SQLQueryParms sqp;
               SQLTypeAdapter sta0("Alex Luya");
               sqp<<sta0;
               SQLTypeAdapter sta1(DateTime("2009-03-04 14:33:31"));
               sqp<<sta1;
               SQLTypeAdapter sta2("synchronizing");
               sqp<<sta2;
               SimpleResult res1 = query.execute(sqp);
           }
           catch (const mysqlpp::Exception& er) {
                cerr << "synchronize-Exception: " << er.what() << endl;
           }
