请参见，每当您向数据库中插入内容时，都需要一条insert语句.

如果要从tableTableAdapter内部调用插入语句，则可以，否则，需要SqlCommand对象来创建命令. :)

See, whenever you are inserting something into database, you need an insert statement.

If you are invoking an insert statement from inside tableTableAdapter then it is fine, otherwise you need SqlCommand object to create your command. :)
