Hello *anonymous user* ,
I did checked the storage explorer and if your entity has a numeric value in the name , it does not allow to create that entity . But I think you can use the column alias and get around this issue . Here is the more details with examples .https://video2.skills-academy.com/en-us/stream-analytics-query/select-azure-stream-analytics
Please do let me know how it goes and if you have any queries .
Thanks
