In SQL Server Management Studio, there's no great way to list all the foreign keys that are defined in a database.
In our free SDU Tools for developers and DBAs, we added a function ListForeignKeys to do just that, and to provide their details in a form that's easy to consume programmatically if you need that.
You can see how to execute it in the main image above. The procedure takes these parameters:
@DatabaseName sysname – This is the database to process
@SchemasToList nvarchar(max) – a comma-delimited list of schemas to include (ie: 'Sales,Purchasing') or the word 'ALL'
@TablesToList nvarchar(max)- a comma-delimited list of tables to include (ie: 'Customers,Orders') or the word 'ALL'
One row is returned for each foreign key.
The columns returned are SourceSchemaName, SourceTableName, ForeignKeyName, SourceColumnList, ReferencedSchemaName, ReferencedTableName, ReferencedColumnList, IsNotTrusted, IsDisabled.
