Generate Foreign Key constraints for all table in Database

SELECT 'ALTER TABLE [dbo].[' +''+  object_name(fk.parent_object_id)+']' AS  ParentTableName, 

   'WITH NOCHECK ADD  CONSTRAINT'+' ['+  fk.[name] +']' ,    

   'FOREIGN KEY([' +''+  COL_NAME(fc.parent_object_id,fc.parent_column_id) +'])' AS  ParentColName ,

   'REFERENCES [dbo].[' +''+  object_name(fk.referenced_object_id) +']' AS  RefTableName,

   '([' +''+    COL_NAME(fc.referenced_object_id,fc.referenced_column_id) +'])' AS  RerfColName ,

   ' NOT FOR REPLICATION'

FROM sys.foreign_keys fk

 INNER JOIN   sys.foreign_key_columns AS fc        

        ON fk.OBJECT_ID = fc.constraint_object_id

 INNER JOIN   sys.tables t 

      ON t.OBJECT_ID = fc.referenced_object_id

--WHERE fc.parent_object_id = object_id('Table_name')

Check DATABASEPROPERTYEX ()

If you are managing more than 'n' of SQL Server database estate in your organisation then you may required to check some times  a specified database current setting in SQL Server to understand.

This below function returns the current setting of the specified database option or property.

DATABASEPROPERTYEX ( database , property )

-- You should defined database name for each function to retrieve the property details

SELECT 
DATABASEPROPERTYEX('AdventureWorks2022', 'Collation') AS Collation, 
DATABASEPROPERTYEX( 'AdventureWorks2022' , 'IsAutoShrink') AS IsAutoShrink  ,
DATABASEPROPERTYEX('AdventureWorks2022', 'Recovery') AS Recovery_State

--Alternatively you can use db_name function for the current database to  retrieve the property details

USE [db_name]
GO
SELECT   
DATABASEPROPERTYEX( db_name() , 'Collation') AS Collation,
DATABASEPROPERTYEX( db_name() , 'IsAutoShrink') AS IsAutoShrink  ,
DATABASEPROPERTYEX( db_name() , 'Recovery') AS Recovery_State

-- Check with Sys.databases to see all the database related property values

SELECT * FROM sys.databases;

Features removed or deprecated in SQL Server 2022

The following features have been removed from SQL Server 2022 that were available in previous releases:

• R, Python, and Java runtimes - R, Python, and Java runtimes are no longer included as part of the setup for SQL Server 2022. The Machine Learning Services feature is still supported, but you'll need to add your own packages that include runtimes you need.

• Polybase Hadoop Connectivity with Java - The Polybase feature with Hadoop connectivity is removed from SQL Server 2022. You can still use Polybase services with ODBC drivers or new REST API based connectors for Azure Blob storage, Azure Data Lake Storage, or S3 compatible object storage.

• Polybase scale out groups - The Polybase scale out group feature has been removed from SQL Server 2022. Queries using external tables or OPENROWSET for data virtualization can take advantage of scale-up processing built into SQL Server.

• Machine Learning Server - Machine Learning Server was retired in July of 2022. Therefore, the Machine Learning Server feature has been removed from the SQL Server setup.

• Distributed Replay - Distributed Reply is no longer available to configure with the setup for SQL Server 2022 on Windows.

• Stretch Database - Stretch Database is deprecated in SQL Server 2022. This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
