In one of my recent projects, a large database migration project, I confronted a peculiar situation. SQL Server tables were already moved from Database_Old to Database_New. However, all the Primary Key and Foreign Keys were yet to be moved from the old server to the new server.
Please note that this puzzle is to be solved for SQL Server 2005 or SQL Server 2008. As noted by Kuldip it is possible to do this in SQL Server 2000.
In SQL Server Management Studio (SSMS), there is no option to script all the keys. If one is required to script keys they will have to manually script each key one at a time. If database has many tables, generating one key at a time can be a very intricate task. I want to throw a question to all of you if any of you have script for the same purpose.
As per my opinion, I think the challenge is to get orders of the column included in Primary Key as well on the filegroup they exist.
Please note here that I am not looking for names of Primary Key or Foreign Key of database. I have already written an article for the same here : SQL SERVER – Two Methods to Retrieve List of Primary Keys and Foreign Keys of Database . I am looking for T-SQL script that generates Primary Key from the existing table for all tables in database.

[AddressID] ASC
) ON [PRIMARY]GO

You can define a primary key in SQL Server by using SQL Server Management Studio or Transact-SQL. Creating a primary key automatically creates a corresponding unique clustered index, or a nonclustered index if specified as such.
Before You Begin
Limitations and Restrictions
Can Sql Server Generate Primary Key In Excel
A table can contain only one PRIMARY KEY constraint.
All columns defined within a PRIMARY KEY constraint must be defined as NOT NULL. If nullability is not specified, all columns participating in a PRIMARY KEY constraint have their nullability set to NOT NULL.
Security
Permissions
Creating a new table with a primary key requires CREATE TABLE permission in the database and ALTER permission on the schema in which the table is being created.
Creating a primary key in an existing table requires ALTER permission on the table.
Using SQL Server Management Studio
To create a primary key
- In Object Explorer, right-click the table to which you want to add a unique constraint, and click Design.
- In Table Designer, click the row selector for the database column you want to define as the primary key. If you want to select multiple columns, hold down the CTRL key while you click the row selectors for the other columns.
- Right-click the row selector for the column and select Set Primary Key.
Sql Server Add Primary Key
Caution
If you want to redefine the primary key, any relationships to the existing primary key must be deleted before the new primary key can be created. A message will warn you that existing relationships will be automatically deleted as part of this process.
A primary key column is identified by a primary key symbol in its row selector.
If a primary key consists of more than one column, duplicate values are allowed in one column, but each combination of values from all the columns in the primary key must be unique.
If you define a compound key, the order of columns in the primary key matches the order of columns as shown in the table. However, you can change the order of columns after the primary key is created. For more information, see Modify Primary Keys.
Using Transact-SQL
To create a primary key in an existing table
The following example creates a primary key on the column TransactionID in the AdventureWorks database.
To create a primary key in a new table
The following example creates a table and defines a primary key on the column TransactionID in the AdventureWorks database.
