Pst = (PreparedStatement) cnx. I am going to use PreparedStatement to get the auto generated id value. Spring provides an easy way to get this auto-generated key using KeyHolder which is supported Spring JDBC 3 onward.
String sql = "INSERT INTO stage1 (ATTESTATION) VALUES (" + selectedPath + ")" In this post I will show you how to get auto generated id of a newly inserted row in table. The main advantage of Prepared Statement is, it will improve the performance when we want to execute the same query multiple times compared to Statement object but if we send different queries using. SelectedPath = selectedPath.replace("\\","\\\\") PreparedStatement is another statement object which is also used to execute all SQL select and non-select statements. ImageIcon icon = new ImageIcon(selectedPath) PreparedStatement.executeUpdate(PreparedStatement.java: 2345) at com. As the question implies, you can use the Java Statement class to issue a MySQL INSERT statement, but the Java PreparedStatement class provides a much better way to insert data into a MySQL database table.
String selectedPath = selected.getAbsolutePath() PreparedStatement.executeUpdate(PreparedStatement.java: 2427) at . Java MySQL INSERT example: Can you share a Java MySQL INSERT example, specifically using a Java PreparedStatement object.
In the previous tutorial, we have shown you how to use the PreparedStatement object to update data.
Remember, you need a Statement in order to execute either a query or an update.You can use a Java JDBC PreparedStatement instead of a Statement and benefit from the features of the PreparedStatement.
This My code JFileChooser f = new JFileChooser("D:\\") įileNameExtensionFilter fnef = new FileNameExtensionFilter("IMAGES", "png", "jpg", "jpeg") Inserting Data Into Table Using JDBC PreparedStatement In this tutorial, you will learn how to use PreparedStatement object to insert data into MySQL table. A Java JDBC PreparedStatement is a special kind of Java JDBC Statement object with some useful additional features.
You will need to provide the query and the parameters passed to the preparedStatement since retrieving them from it is a bit of a pain: private String generateActualSql(String sqlQuery, .圎rrorException: You have an error in your SQL syntax check the manual that corresponds to your MariaDB server version for the right syntax to use near ':\\wallpaper\\a.jpg)' at line 1Īt 0(Native Method)Īt (NativeConstructorAccessorImpl.java:62)Īt (DelegatingConstructorAccessorImpl.java:45)Īt .newInstance(Constructor.java:423)Īt .handleNewInstance(Util.java:411)Īt .getInstance(Util.java:386)Īt .createSQLException(SQLError.java:1053)Īt .checkErrorPacket(MysqlIO.java:4120)Īt .checkErrorPacket(MysqlIO.java:4052)Īt .sendCommand(MysqlIO.java:2503)Īt .sqlQueryDirect(MysqlIO.java:2664)Īt .execSQL(ConnectionImpl.java:2788)Īt .executeUpdate(StatementImpl.java:1816)Īt .executeUpdate(StatementImpl.java:1730)Īt 7MouseClicked(Dossier.java:355)Īt $500(Dossier.java:30)Īt stage.Dossier$6.mouseClicked(Dossier.java:171)Īt (Component.java:6542)Īt (JComponent.java:3324)Īt (Component.java:6304)Īt (Container.java:2239)Īt (Component.java:4889)Īt (Container.java:2297)Īt (Component.java:4711)Īt (Container.java:4904)Īt (Container.java:4544)Īt (Container.java:4476)Īt (Container.java:2283)Īt (Window.java:2746)Īt (EventQueue.java:760)Īt $500(EventQueue.java:97)Īt $3.run(EventQueue.java:709)Īt $3.run(EventQueue.java:703)Īt (Native Method)Īt $JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:74)Īt $JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:84)Īt $4.run(EventQueue.java:733)Īt $4.run(EventQueue.java:731)Īt (EventQueue.java:730)Īt (EventDispatchThread.java:205)Īt (EventDispatchThread.java:116)Īt (EventDispatchThread.java:105)Īt (EventDispatchThread.java:101)Īt (EventDispatchThread.java:93)Īt (EventDispatchThread.java:82) The JDBC specification is flexible on how certain functionality should be implemented.
