我有一个数据库，我使用UUID作为主键。我使用java将uuids存储为二进制文件（16）。要保存条目，请使用以下

这部分正常，我可以在数据库中查看我的条目。
但是一旦我尝试加载条目：
public boolean saveEntry(UUID id , String, name, int p1, int p2) throws SQLException
{
byte[] uuidBytes = new byte[16];
ByteBuffer.wrap(uuidBytes).order(ByteOrder.BIG_ENDIAN).putLong(id.getMostSignificantBits())
.putLong(id.getLeastSignificantBits());
String updateQuery = "INSERT INTO " + databaseTableName + " (ID, Name, p1, p2) "
+ "VALUES " + "(?, ?, ?, ?) "
PreparedStatement statement = null;
// write the id in the workflow table
statement = databaseConnection.prepareStatement(updateQuery);
statement.setBytes(1, uuidBytes);
statement.setString(2, name);
statement.setInt(3, p1);
statement.setInt(4, p2);
statement.execute();
我得到以下错误：
您的SQL语法有错误;检查手册 对应于您的MySQL服务器版本，以便使用正确的语法 靠近＆＃39;？＆＃39;在第1行
我不太确定错误的原因是什么。我知道使用public Workflow loadEntry(UUID id) throws SQLException
{
byte[] uuidBytes = new byte[16];
ByteBuffer.wrap(uuidBytes).order(ByteOrder.BIG_ENDIAN).putLong(id.getMostSignificantBits())
.putLong(id.getLeastSignificantBits());
String query = "SELECT " + "* " + "FROM " + databaseTableName + " WHERE " + databaseTableName
+ ".ID = ?";
PreparedStatement preparedStatement = null;
ResultSet resultSet = null;
try
{
preparedStatement = databaseConnection.prepareStatement(query);
preparedStatement.setBytes(1, uuidBytes);
resultSet = preparedStatement.executeQuery(query);
有效，但我不确定这种方式的性能和功能。那么有什么方法可以解决这个问题吗？
