Which functions are not supported in Fabric that a BI professional must be aware of?

[deep_pr97]

Few functions such as datepart, merge are not supported in fabric. There are few mentioned in the link https://learn.microsoft.com/en-us/fabric/data-warehouse/tsql-surface-area#limitations. What other functions are not supported?

Hi, what specific functions are you looking for; Fabric as a whole or only the warehouse? If you are talking about Fabric as a whole, you could argue that the CI/CD-process misses some crucial elements and the support of the gateway in Notebooks. However, those are not always used in all scenario's. I would advise you to look at your specific requirements and see if Fabric could fulfill those requirements.

If you particularly mean the warehouses within Fabric, I think you have most of the limitations already in the link you shared, here are a few bullet points more: https://learn.microsoft.com/en-us/fabric/data-warehouse/limitations

Fabric also published the SQL database in preview which has less T-SQL limitations, but that doesn't mean it is a better fit, expecially for BI purposes. You can take a look at the new SQL database here: https://learn.microsoft.com/en-us/fabric/database/sql/overview

Not exactly as BI but if working on DE tasks, you can check them out.

HI @deep_pr97,

If you're talking Fabric Warehouse T-SQL limitations, I covered that in a forum response the other day: https://community.fabric.microsoft.com/t5/Data-Warehouse/Fabric-DW-from-SQL-server/m-p/4334872#M2264

If you are looking outside of Fabric warehouses, please clarify what limitations you are referring to.
