SQL Pool

STEP 7: Grant access to SQL pools

By default, all users assigned the Synapse Administrator role are also assigned the SQL db_owner role on the serverless SQL pools in the workspace.

SQL Pool - master

List of server-role members

SELECT  roles.principal_id  AS RolePrincipalID
    ,   roles.name AS RolePrincipalName
    ,   server_role_members.member_principal_id AS MemberPrincipalID
    ,   members.name AS MemberPrincipalName
FROM sys.server_role_members AS server_role_members
INNER JOIN sys.server_principals AS roles
    ON server_role_members.role_principal_id = roles.principal_id
INNER JOIN sys.server_principals AS members 
    ON server_role_members.member_principal_id = members.principal_id ;

Listing all principals (SQL authentication) which are members of a server-level role

SELECT
        sql_logins.principal_id         AS MemberPrincipalID
    ,   sql_logins.name                 AS MemberPrincipalName
    ,   roles.principal_id              AS RolePrincipalID
    ,   roles.name                      AS RolePrincipalName
FROM sys.server_role_members AS server_role_members
INNER JOIN sys.server_principals AS roles
    ON server_role_members.role_principal_id = roles.principal_id
INNER JOIN sys.sql_logins AS sql_logins 
    ON server_role_members.member_principal_id = sql_logins.principal_id
;  
GO

SQL Pool - Use Database: YourDatabase

-- User

select * from sys.database_principals where [type] <> 'R';

-- Database Role and member

SELECT DP1.name AS DatabaseRoleName,   
   isnull (DP2.name, 'No members') AS DatabaseUserName   
 FROM sys.database_role_members AS DRM  
 RIGHT OUTER JOIN sys.database_principals AS DP1  
   ON DRM.role_principal_id = DP1.principal_id  
 LEFT OUTER JOIN sys.database_principals AS DP2  
   ON DRM.member_principal_id = DP2.principal_id  
WHERE DP1.type = 'R'
ORDER BY DP1.name;

Master or User-DB

Build-In

(Serverless SQL pool)

no local storage, only metadata objects are stored in databases. following T-SQL isn't supported:

l Tables

l Triggers

l Materialized views

l DDL statements other than ones related to views and security

l DML statements

You can use CETAS - CREATE EXTERNAL TABLE AS SELECT

YourDedicatedSQLPool

(Dedicated SQL pool)

All support

三種情境

The user can be an Azure Active Directory authentication contained database user (if you've configured your environment for Azure AD authentication) 就是用Azure AD的Contained database user帳號
a SQL Server authentication contained database user 也就是SQL驗證的Contained database user帳號 (此情境在Synapse不支援)
a SQL Server authentication user based on a SQL Server authentication login (created in the previous step.) 是SQL驗證的SQL驗證Login登入帳號

1.Azure AD的Contained database user帳號

CREATE USER [devuser1@yourdomain.onmicrosoft.com] from External PROVIDER;

EXEC sp_addrolemember 'db_owner', 'devuser1@yourdomain.onmicrosoft.com';

如果想建立SQL驗證的Contained database user帳號，則會出現語法錯誤，而無法建立

Contained Database Users - Making Your Database Portable

Azure: SQL Database and Azure Synapse Analytics support Azure Active Directory identities as contained database users. SQL Database supports contained database users using SQL Server authentication, but Azure Synapse Analytics does not. For more information, see Connecting to SQL Database By Using Azure Active Directory Authentication. When using Azure Active Directory authentication, connections from SSMS can be made using Active Directory Universal Authentication. Administrators can configure Universal Authentication to require Multi-Factor Authentication, which verifies identity by using a phone call, text message, smart card with pin, or mobile app notification. For more information, see SSMS support for Azure AD MFA with SQL Database and Azure Synapse Analytics.

所以以下這篇文件的描述有誤，因為Synapse不支援

SQL Authentication in Azure Synapse Analytics

2.SQL驗證的Contained database user帳號 (此情境在Synapse不支援)

3.SQL驗證的SQL驗證Login登入帳號

CREATE LOGIN [ApUser1] WITH PASSWORD = '340$Uuxwp7Mcxo7Khy';

CREATE USER [ApUser1] FROM LOGIN [ApUser1];

EXEC sp_addrolemember 'db_owner', 'ApUser1';

	master	UserDB
Build-In (Serverless SQL pool)	CREATE LOGIN [alias@domain.com] FROM EXTERNAL PROVIDER 建立網域帳號的登入時，管理員執行CREATE LOGIN語法的帳號必須是AD帳號，不然會出現錯誤(找不到使用者alias@domain.com) ALTER SERVER ROLE sysadmin ADD MEMBER [alias@domain.com]; CREATE LOGIN [sqladmin1] WITH PASSWORD = '340$Uuxwp7Mcxo7Khy' ALTER SERVER ROLE sysadmin ADD MEMBER [sqladmin1];
YourDedicatedSQLPool (Dedicated SQL pool)	CREATE LOGIN [alias@domain.com] FROM EXTERNAL PROVIDER CREATE LOGIN User1 WITH PASSWORD = '340$Uuxwp7Mcxo7Khy' In Azure SQL Database or synapse serverless, use the ALTER ROLE statement. ALTER SERVER ROLE sysadmin ADD MEMBER [alias@domain.com]; ALTER SERVER ROLE sysadmin ADD MEMBER [sqladmin1];	CREATE USER [alias@domain.com] FOR LOGIN [alias@domain.com] CREATE USER [User1] FOR LOGIN [User1] EXEC sp_addrolemember 'db_owner', 'Mary'; EXEC sp_addrolemember 'db_datawriter', 'Mary'; EXEC sp_addrolemember 'db_datareader’, 'Mary';

To grant full access to all serverless SQL pools in the workspace, in the master database

Azure Active Directory authorization: (可透過Synapse Studio web或SSMS登入)

CREATE LOGIN [alias@domain.com] FROM EXTERNAL PROVIDER;

ALTER SERVER ROLE sysadmin ADD MEMBER [alias@domain.com];

SQL authorization: (通常透過SSMS登入)

CREATE LOGIN Mary WITH PASSWORD = '340$Uuxwp7Mcxo7Khy';

ALTER SERVER ROLE sysadmin ADD MEMBER [Mary];

Synapse Studio

https://web.azuresynapse.net/

需先給予Synapse workspace權限，例如Contributor，在 https://web.azuresynapse.net/ 才能選到Azure Subscription與synapse workspace

The Serverless SQL pool has no local storage, only metadata objects are stored in databases. Therefore, T-SQL related to the following concepts isn't supported:

Tables
Triggers
Materialized views
DDL statements other than ones related to views and security
DML statements

You can use CETAS - CREATE EXTERNAL TABLE AS SELECT or instead you can create a provisioned SQL Pool.
