GUID_PK in SQL Server - sql-server

Question

When I execute this query, I am getting an error
Cannot find data type dbo.GUID_PK
For this should I create table for CandidateRoleID or what else should I do here?
But, when I googled it I found it saying SQL Server stores GUID. How could I access it or what is the correct way of declaring this table? I searched in google about GUID_PK.
But didn't find any syntax or explanation. Thanks in advance.
CREATE TABLE [dbo].[tbl]
(
[CandidateRoleID] [dbo].[GUID_PK] NOT NULL,
[CandidateID] [uniqueidentifier] NOT NULL,
[RoleID] [int] NOT NULL
);

Answer 1

The SQL server data type for a GUID is UNIQUEIDENTIFIER.
Your script should be:
CREATE TABLE [dbo].[tbl](
[CandidateRoleID] [uniqueidentifier] NOT NULL,
[CandidateID] [uniqueidentifier] NOT NULL,
[RoleID] [int] NOT NULL,
CONSTRAINT PK_Tbl PRIMARY KEY (CandidateRoleID));
If you want it to be 'automatically' created, similar to an integer identity column, give it a default:
CREATE TABLE [dbo].[tbl](
[CandidateRoleID] [uniqueidentifier] NOT NULL DEFAULT NEWID(),
[CandidateID] [uniqueidentifier] NOT NULL,
[RoleID] [int] NOT NULL,
CONSTRAINT PK_Tbl PRIMARY KEY (CandidateRoleID));

Answer 2

CREATE TABLE [dbo].[tbl](
[CandidateRoleID] [uniqueidentifier] primary key NOT NULL,
[CandidateID] [uniqueidentifier] NOT NULL,
[RoleID] [int] NOT NULL,
);
In SQL server GUID is uniqueidentifier data type.

There is no data type 'GUID_PK' in sql server.
GUID is an acronym for Global Unique ID(entifier) and is a unique 16
byte number. The term GUID and UNIQUEIDENTIFIER are often
interchangeable within the SQL Server community.
If you need to auto-generate uniqueidentifier value in your table during data insert, the consider adding default value to the uniqueidentifier data-type.
CREATE TABLE #tbl(
[CandidateRoleID] [uniqueidentifier] NOT NULL DEFAULT NEWID(),
[CandidateID] [uniqueidentifier] NOT NULL DEFAULT NEWID(),
[RoleID] [int] NOT NULL);
GO
INSERT INTO #tbl (ROLEID) SELECT (1)
CandidateRoleID CandidateID RoleID
