Creating foreign key in SQL Server Management Studio Using SQL Server R2 I am trying to establish a relationship between two. Primary key, Foreign Key and Default constraint are the 3 main constraints that need to be considered while creating tables or even after that. To view the foreign key attributes of a relationship in a Table Column Properties (SQL Server Management Studio).
The increase has the following restrictions: MERGE operations are not supported.
A table with a foreign key reference to itself is still limited to foreign key references. Greater than foreign key references are not currently available for columnstore indexes, memory-optimized tables, or Stretch Database. If a foreign key is defined on a CLR user-defined type column, the implementation of the type must support binary ordering.
