Since the official account has been in operation, it is inseparable from the support of friends.
Several WeChat groups established before are currently full. In order to provide a communication platform for learning SQL for friends who follow us in the future, we have established a SQL database development group. Welcome friends to join!
In order to create a good communication environment, we should first understand the group rules before joining the group:
1. Please be sure to modify the business card when entering the group, the format: City-Title-Name, thank you for your cooperation~
2. Please do not send advertisements, QR codes, small programs, politically sensitive content and disturb other group friends, except for good resource sharing. Once found, the group chat will be removed. Thank you for your support~
3. If you have any questions, you can directly communicate in the group. If someone contacts you privately, please do not be deceived, and you can give me feedback in time.
4. Learn from each other, communicate with each other, make progress together, and create a good learning atmosphere together!
