mysql - Using Timestamp in java sql prepared statement -


i trying execute select query using prepared statement in java. in clause im checking condition on timestamp type column shown below.

string selectsql = "select * db.keycontacts createddatetime>?"; preparedstatement preparedstatement = connect.preparestatement(selectsql); preparedstatement.settimestamp(1, convertstrtotimestamp(lastsynctimestamp)); resultset = preparedstatement.executequery(selectsql );

//function convert timestampstring java.sql.timestamp

private java.sql.timestamp convertstrtotimestamp(string datetimestr){        java.sql.timestamp timestampdate = null;       try {             dateformat formatter = new simpledateformat("yyyy-mm-dd hh:mm:ss");//2015-05-11 18:26:55             java.util.date dateobj = (java.util.date)formatter.parse(datetimestr);             timestampdate = new timestamp(dateobj.gettime());         } catch (parseexception e) {             // todo auto-generated catch block             e.printstacktrace();         }        return timestampdate;   }

when query executed, getting following exception.

com.mysql.jdbc.exceptions.jdbc4.mysqlsyntaxerrorexception: have error in sql syntax; check manual corresponds mysql server version right syntax use near '?' @ line 1

so im going wrong here?

thanks in advance.

remove parameter from

resultset = preparedstatement.executequery(selectsql );

and change to

resultset = preparedstatement.executequery( );

the query passed in preparedstatement.executequery(selectsql ); takes priority on query passed in connect.preparestatement(selectsql); simple string ("select * db.keycontacts createddatetime>?") in dint set parameter there syntax error ?

and can statement prepared @ preparedstatement preparedstatement = connect.preparestatement(selectsql); since executequery() inherited statement execute query without preparing it.
