NET Framework Library, which provides an extensive set of classes that can be used to quickly and efficiently solve programming problems.
Developers may also leverage the power of the. NET Framework languages are in many respects richer than Transact-SQL, offering constructs and capabilities previously not available to SQL Server developers. Some of the benefits of the server-side CLR integration are:Ī better programming model. NET Framework such as regular expressions, code for accessing external resources (servers, web services, databases), custom encryption, etc. This 6-minute video shows you how to use CLR in Azure SQL Managed Instance:ĬLR Integration enables you to implement complex features that are available in. For more information, see sys.sp_add_trusted_assembly. SQL Server administrators can also add assemblies to a list of assemblies, which the Database Engine should trust. For more information, see CLR strict security. Microsoft recommends that all assemblies be signed by a certificate or asymmetric key with a corresponding login that has been granted UNSAFE ASSEMBLY permission in the master database. The clr strict security option can be disabled for backward compatibility, but this is not recommended. clr strict security is enabled by default, and treats SAFE and EXTERNAL_ACCESS assemblies as if they were marked UNSAFE. Beginning with SQL Server 2017 (14.x), an sp_configure option called clr strict security is introduced to enhance the security of CLR assemblies. A CLR assembly created with PERMISSION_SET = SAFE may be able to access external system resources, call unmanaged code, and acquire sysadmin privileges.
NET Framework, which is no longer supported as a security boundary. CLR uses Code Access Security (CAS) in the.
