不能用preparedStatement创建表

Question

我不能在数据库中创建（MySQL的）表，使用preparedStatement并尝试进入未来表的名称preparedStatement.setInteger()

static String queryCreateTable = "CREATE TABLE ?" +
                                 "(ID INTEGER not NULL ," +
                                 "BRAND VARCHAR(40)," +
                                 "MODEL VARCHAR(40)," +
                                 "YEAR INTEGER not NULL," +
                                 "NOVELTY BINARY," +
                                 "PRIMARY KEY ( ID ))";

然后我尝试在用户输入表名后构造并调用该语句：

newNameOfTable = JOptionPane.showInputDialog("Connected for saving data. " +
                                "Input name of new table:");

                        pStatement = connection.prepareStatement(queryCreateTable);
                        pStatement.setString(1, newNameOfTable);
                        pStatement.executeUpdate();

如果我尝试在不输入名称的情况下执行它（如常量字符串：“CREATE TABLE newtable (...)”但我需要输入名称..

读取表名后，您必须格式化字符串，例如：

static String queryCreateTable = "CREATE TABLE {0}" +
                                 "(ID INTEGER not NULL ," +
                                 "BRAND VARCHAR(40)," +
                                 "MODEL VARCHAR(40)," +
                                 "YEAR INTEGER not NULL," +
                                 "NOVELTY BINARY," +
                                 "PRIMARY KEY ( ID ))";

然后创建如下：

newNameOfTable = JOptionPane.showInputDialog("Connected for saving data. " +
                            "Input name of new table:");

statement = connection.createStatement();
statement.execute(MessageFormat.format(queryCreateTable, newNameOfTable));

Answer 2

newNameOfTable = JOptionPane.showInputDialog("Connected for saving data. " +
                                "Input name of new table:");

static String queryCreateTable = "CREATE TABLE " + newNameOfTable +
                                 "(ID INTEGER not NULL ," +
                                 "BRAND VARCHAR(40)," +
                                 "MODEL VARCHAR(40)," +
                                 "YEAR INTEGER not NULL," +
                                 "NOVELTY BINARY," +
                                 "PRIMARY KEY ( ID ))";


pStatement = connection.prepareStatement(queryCreateTable);
pStatement.executeUpdate();
