1.用DataBase执行
DataBase db = new DataBase();
db.executeStatement("update or delete");

2.用QueryProvider对象
String url = "jdbc:oracle:thin:@ipadd:1521:server";
String driverName = "oracle.jdbc.driver.OracleDriver";
String userName = "user";
String password = "pwd
boolean flg = false;
Database db = new Database();
ConnectionDescriptor cndp = new ConnectionDescriptor(url, userName, password, flg, driverName);
ParameterRow pr = new ParameterRow();
QueryProvider qp = new QueryProvider();
db.setConnection(cndp);
pr.addColumn("name", Variant.STRING, ParameterType.IN);
pr.setString("name", "a");
qp.executeStatement(db,"delete from test where name=:name",pr);
db.closeConnection();
