MERGE JDBCTemplate issue

Question

I know my questions is similar to this question : UPDATE on INSERT duplicate primary key in Oracle?

actually exact copy.

I am new to spring framework. so this is my first attempt. I have tried ,many examples but failed miserably.

So here is the thing.

My source and target is the same.what i want is to update the record if its in the Db otherwise insert.

i am using the following method. My insert query is working fine. But when i use MERGE. i am getting errors.

public void insertAllPointss(final List<AllPoints> allpoints) {


//      String sql = "INSERT INTO myTable " +
//                  "(WIFI_SEQ_NO, my_urlL, street_number, house_number, street_name, last_update) VALUES (seq_w.NEXTVAL, ?, ?, ?, ?, ?) ";

         String sql = "MERGE INTO myTable M" +
                  " USING (SELECT ? AS my_urlL, ? AS street_number, ? AS house_number,? AS street_name, ? AS last_update FROM dual) N"+
                    "  ON (M.street_number = N.street_number AND M.house_number = N.house_number AND M.street_name = N.street_name)"+
                  " WHEN MATCHED THEN UPDATE SET M.last_update = N.last_update"+
                  " WHEN NOT MATCHED THEN INSERT(WIFI_SEQ_NO, my_urlL, street_number, house_number, street_name, last_update)"+
                                       "  VALUES(seq_w.NEXTVAL, N.my_urlL, N.street_number, N.house_number, N.street_name, N.last_update)";

          getJdbcTemplate().batchUpdate(sql, new BatchPreparedStatementSetter() {

              Calendar calendar = Calendar.getInstance();
              java.sql.Date ourJavaDateObject = new java.sql.Date(calendar.getTime().getTime());
            @Override
            public void setValues(PreparedStatement ps, int i) throws SQLException {
                AllPoints allpoints = AllPointss.get(i);
                ps.setString(1, AllPoints.getWebsite());
                ps.setDouble(2, allpoints.getStreetNumber());
                ps.setDouble(3, allpoints.getHouseNumber());
                ps.setString(4, allpoints.getStreetName());
                ps.setDate(5, ourJavaDateObject);
            }

            @Override
            public int getBatchSize() {
                return AllPointss.size();
            }
          });


        }

following is my log file

Correct Syntax use:

MERGE INTO people AS t 
USING (
    VALUES  (5, 'Chuck', 'Norris'),
                 (6, 'John', 'Smith'),
                 (7, 'Abraham', 'Lincoln')
                 -- maybe more rows
       ) AS s (id, name, surname)
    ON t.id = s.id
    WHEN MATCHED THEN
        UPDATE SET t.name=s.name, t.surname=s.surname
    WHEN NOT MATCHED THEN
        INSERT (id, name, surname)
              VALUES (s.id, s.name, s.surname)
