In MySQL, if you try to execute an INSERT statement that does not provide a value for a NOT NULL column, the command is successful. 在MySQL中,如果要执行一个不提供NOTNULL列值的INSERT语句,此命令没有问题。
Each message, or frame, starts with a command and ends with the ASCII sign for a null character. 每个消息(即帧)以一个命令开头,以一个表示null字符的ASCII符号结束。
