MERGE JDBCTemplate Ausgabe

Question

ich meine Fragen wissen, ist, ähnlich wie diese Frage: UPDATE on INSERT duplicate primary key in Oracle?

tatsächlich exakte Kopie.

Ich bin neu im Frühling Rahmen. also das ist mein erster Versuch. Ich habe versucht, viele Beispiele, aber scheiterte kläglich.

Also hier ist die Sache.

Meine Quelle und Ziel ist die selbe.Was ich will, ist es, den Datensatz zu aktualisieren, wenn es in das DB sonst einfügen.

Ich verwende die folgende Methode. Meine Einfügeabfrage funktioniert einwandfrei. Aber wenn ich MERGE benutze. Ich bekomme Fehler.

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(); 
      } 
      }); 


     }

ich fühle mich gibt es ein Problem meiner MERGE SQL-Anweisung, ich bin auf der Suche nach etwas Hilfe/Anleitung

Answer 1

korrekte Syntax:

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)
