fabric datawarehouse

[arkiboys2]

hello,

It looks like it is not possible to create keys or index on a table in the warehouse.

is this right?

the messsage says: primary key or unique keyword is not supported in the create table statement in this edition of sql server.

and not sure if my fabric warehouse should be upgraded? 

current version: 12.0.2000.8 oct 22 2024

thanks

Hi, it is true that it is not possible to create keys or index on a table in the warehouse. Here is the documentation that mentions that limitation: https://learn.microsoft.com/en-us/fabric/data-warehouse/tables#limitations

is there a workaround?

You could use row_number or hashing your rows to get unique values for every row.

Hi, @arkiboys2 

Thanks for FabianSchut‘s reply. As he said, currently Warehouse doesn't support the creation of unique indexes and there are some limitations for primary keys, you can try his method for your data and if it doesn't work, it's recommended to submit an idea for here and the product team will take note of such a need.
