Article Introduction：When handling NULL values ??in MySQL, please note: 1. When designing the table, the key fields are set to NOTNULL, and optional fields are allowed NULL; 2. ISNULL or ISNOTNULL must be used with = or !=; 3. IFNULL or COALESCE functions can be used to replace the display default values; 4.

Article Introduction：WebRTC is a free, open source technology that supports real-time communication between browsers and devices. It realizes audio and video capture, encoding and point-to-point transmission through built-in API, without plug-ins. Its working principle includes: 1. The browser captures audio and video input; 2. The data is encoded and transmitted directly to another browser through a security protocol; 3. The signaling server assists in the initial connection but does not participate in media transmission; 4. The connection is established to achieve low-latency direct communication. The main application scenarios are: 1. Video conferencing (such as GoogleMeet, Jitsi); 2. Customer service voice/video chat; 3. Online games and collaborative applications; 4.
