我是否在PreparedStatement 中错误地使用了语法？

执行时：

1    statement = conn.prepareStatement("insert into ?.? (?) values(?)");
2    statement.setString(1, schemaName);
3    statement.setString(2, tableName);
4    statement.setString(3, columnName);
5    statement.setString(4, columnValue);
6    statement.executeUpdate();
7    conn.commit();

抛出的异常：
