Synonym for any of the preceding items Directory, library, operator, or indextype Java source, class, or resource You cannot grant privileges directly to a single partition of a partitioned table. If you do not qualify object with schema, then the database assumes that the object is in your own schema.
In particular, this article gets you started with resources for limiting access, protecting data, and monitoring activities on a database.
Connection security Connection Security refers to how you restrict and secure connections to your database using firewall rules and connection encryption. Firewall rules are used by both the server and the database to reject connection attempts from IP addresses that have not been explicitly whitelisted.
As a best practice, you should restrict the IP address ranges allowed through your server firewall as much as possible. SQL Data Warehouse uses server-level firewall rules. It does not support database-level firewall rules. Modifying connection settings to disable encryption are ignored.
Authentication Authentication refers to how you prove your identity when connecting to the database. When you created the logical server for your database, you specified a "server admin" login with a username and password. Using these credentials, you can authenticate to any database on that server as the database owner, or "dbo" through SQL Server Authentication.
This way you can limit the permissions granted to the application and reduce the risks of malicious activity in case your application code is vulnerable to a SQL injection attack.
To create a SQL Server Authenticated user, connect to the master database on your server with your server admin login and create a new server login. Creating a user in master allows a user to log in using tools like SSMS without specifying a database name.
It also allows them to use the object explorer to view all databases on a SQL server. Authorization privileges are determined by role memberships and permissions.
As a best practice, you should grant users the least privileges necessary. To manage roles, you can use the following stored procedures: Save this account for deploying schema upgrades and other management operations.
Use the "ApplicationUser" account with more limited permissions to connect from your application to the database with the least privileges needed by your application.
Granular Permissions let you control which operations you can do on individual columns, tables, views, schemas, procedures, and other objects in the database. Use granular permissions to have the most control and grant the minimum permissions necessary.
The built-in fixed database roles provide an easy way to grant permissions, but can result in granting more permissions than are necessary. Stored procedures can be used to limit the actions that can be taken on the database.
The following example grants read access to a user-defined schema. Test to ApplicationUser Managing databases and logical servers from the Azure portal or using the Azure Resource Manager API is controlled by your portal user account's role assignments.
For more information, see Role-based access control in Azure portal.The MySQL server maintains many system variables that configure its operation.
Each system variable has a default value. System variables can be set at server startup using options on the command line or in .

In this article, Gail Shaw looks at how you can identify common types of deadlock, the difference between a deadlock and severe blocking, and how to avoid and fix the most common deadlock types.

Write SQL Server Audit Events to the Security Log. 09/21/; 3 minutes to read Contributors. all; In this article APPLIES TO: SQL Server Azure SQL Database Azure SQL Data Warehouse Parallel Data Warehouse In a high security environment, the Windows Security log is the appropriate location to write events that record object access.
Notes on Authorizing Database Users You can authorize database users through means other than the database and the GRANT statement.. Many Oracle Database privileges are granted through supplied PL/SQL and Java packages. For information on those privileges, refer to the documentation for the appropriate package.
In this post, we’ll address a common question about how to write an AWS Identity and Access Management (IAM) policy to grant read-write access to an Amazon S3 bucket. Doing so helps you control who can access your data stored in Amazon S3.
I would like to write a query on a sql that will report all the users that have access to a specific database, or objects within the database such as tables, views, and stored procedures, either directly or due to roles, etc.
