[java] Multiple queries executed in java in single statement

Hi I was wondering if it is possible to execute something like this using JDBC as it currently provides an exception even though it is possible in the MySQL query browser.

"SELECT FROM * TABLE;INSERT INTO TABLE;"

While I do realize that it is possible with having the SQL query string being split and the statement executed twice but I was wondering if there is a one time approach for this.

    String url = "jdbc:mysql://localhost:3306/";
    String dbName = "databaseinjection";
    String driver = "com.mysql.jdbc.Driver";
    String sqlUsername = "root"; 
    String sqlPassword = "abc";

    Class.forName(driver).newInstance();

    connection = DriverManager.getConnection(url+dbName, sqlUsername, sqlPassword);

I think this is the easiest way for multy selection/update/insert/delete. You can run as many update/insert/delete as u want after select (you have to make a select first(a dummy if needed)) with executeUpdate(str) (just use new int(count1,count2,...)) and if u need a new selection close 'statement' and 'connection' and make new for next select. Like example:

String str1 = "select * from users";
String str9 = "INSERT INTO `port`(device_id, potition, port_type, di_p_pt) VALUE ('"+value1+"', '"+value2+"', '"+value3+"', '"+value4+"')";
String str2 = "Select port_id from port where device_id = '"+value1+"' and potition = '"+value2+"' and port_type = '"+value3+"' ";
try{  
    Class.forName("com.mysql.jdbc.Driver").newInstance();
    theConnection=(Connection) DriverManager.getConnection(dbURL,dbuser,dbpassword);  
    theStatement = theConnection.prepareStatement(str1);
    ResultSet theResult = theStatement.executeQuery();
    int count8 = theStatement.executeUpdate(str9);
    theStatement.close();
    theConnection.close();
    theConnection=DriverManager.getConnection(dbURL,dbuser,dbpassword);
    theStatement = theConnection.prepareStatement(str2);
    theResult = theStatement.executeQuery();

    ArrayList<Port> portList = new ArrayList<Port>();
    while (theResult.next()) {
        Port port = new Port();
        port.setPort_id(theResult.getInt("port_id"));

        portList.add(port);
    }

I hope it helps

Based on my testing, the correct flag is "allowMultiQueries=true"

Why dont you try and write a Stored Procedure for this?

You can get the Result Set out and in the same Stored Procedure you can Insert what you want.

The only thing is you might not get the newly inserted rows in the Result Set if you Insert after the Select.

Hint: If you have more than one connection property then separate them with:

&

To give you somthing like:

url="jdbc:mysql://localhost/glyndwr?autoReconnect=true&allowMultiQueries=true"

I hope this helps some one.

You can use Batch update but queries must be action(i.e. insert,update and delete) queries

Statement s = c.createStatement();
String s1 = "update emp set name='abc' where salary=984";
String s2 = "insert into emp values ('Osama',1420)";  
s.addBatch(s1);
s.addBatch(s2);     
s.executeBatch();
