What is CLR integration?

The common language runtime (CLR) is the heart of the Microsoft . With the CLR hosted in Microsoft SQL Server (called CLR integration), you can author stored procedures, triggers, user-defined functions, user-defined types, and user-defined aggregates in managed code.

What language is DLL written in?

C calling
The DLL uses the C calling convention. It can be called from apps written in other programming languages, as long as the platform, calling conventions, and linking conventions match. The client app uses implicit linking, where Windows links the app to the DLL at load-time.

What are the disadvantages of using stored procedure?

Drawbacks of Stored Procedures

• Testability. First and foremost business logic which is encapsulated in stored procedures becomes very difficult to test (if tested at all).
• Debugging.
• Versioning.
• History.
• Branching.
• Runtime Validation.
• Maintainability.
• Fear of change.

Where are CLR functions stored?

database
1 Answer. Deployed User CLR assemblies are stored in the database you deploy them to, not on the file system. the column called content contains binary data is the assembly.

Which is an example of an extended procedure?

Examples of these include sp_executesql, sp_xml_preparedocument, most of the sp_cursor routines, sp_reset_connection, and so forth. These routines have stubs in master..sysobjects, and are listed as extended procedures, but they are actually implemented internally by the server, not within an external ODS-based DLL.

How to debug an extended stored procedure DLL?

To debug an extended stored procedure DLL, copy it to the SQL Server\Binn directory. To specify the executable for the debugging session, enter the path and file name of the Microsoft SQL Server executable file (for example, C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Binn\Sqlservr.exe).

Can a stored procedure be called from any database?

Because sp_hexstring is a system procedure, it can be called from any database without requiring the caller to reference xp_varbintohexstr directly. Internal Procedures A number of system-supplied stored procedures are neither true system procedures nor extended procedures—they’re implemented internally by SQL…
