Support for primary keys and foreign keys

[pmscorca]

Hi,

I'd like to know if Fabric SQL database supports the primary keys and the foreign keys for tables.

I hope that this is possible, otherwise for which reasons.

Thanks

Hi @pmscorca ,

It supports primary key, please do check the limitations.

Hi pmscorca,

Please check the below Microsoft documentation link:

Table constraints

SQL analytics endpoint and Warehouse in Microsoft Fabric support these table constraints:

• PRIMARY KEY is only supported when NONCLUSTERED and NOT ENFORCED are both used.
• FOREIGN KEY is only supported when NOT ENFORCED is used.
• UNIQUE constraint is only supported when NONCLUSTERED and NOT ENFORCED are both used.

Hi, but I'm referring to a Fabric SQL Database and not warehouse/lakehouse.

Thanks

Hi @pmscorca , Fabric SQL database supports primary keys/foreign keys and all other objects that you may be familiar in Azure SQL Database or SQL Server.
