不能用preparedStatement創建表

Question

我不能在數據庫中創建（MySQL的）表，使用preparedStatement並嘗試進入未來表的名稱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 ))";

然后我嘗試在用戶輸入表名后構造並調用該語句：

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

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

如果我嘗試在不輸入名稱的情況下執行它（如常量字符串：“CREATE TABLE newtable (...)”但我需要輸入名稱..

Answer 1

讀取表名后，您必須格式化字符串，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 ))";

然后創建如下：

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();
