Hi @suppagorn chaoumdee,
SQL Server Developer edition includes all the functionality of Enterprise edition, but is licensed for use as a development and test system, not as a production server.
When you install SQL Server Developer Edition, the license terms are copied to a location like:
C:\Program Files\Microsoft SQL Server\150\License Terms\SQLServer2019_License_DEV_1033.rtf
You can read it. The license states, in relevant part:
1. INSTALLATION AND USE RIGHTS. a. General. You may install and use copies of the software on any device, including third party shared devices, to design, develop, test and demonstrate your programs. You may not use the software in a production environment.
b. Demonstration. Any person that has access to your internal network may install and use copies of the software to demonstrate use of your programs with the software. Those copies may not be used for any other purpose.
c. User Testing. Your end users may access the software to perform acceptance tests on your programs.
Regards,
Zoe Hui
