Stairway to SQLCLR Level 4: Security (EXTERNAL and UNSAFE Assemblies)

In the fourth level of our Stairway to SQLCLR series we take a detailed look at the EXTERNAL_ACCESS and UNSAFE permission sets. We also explore some differences between using TRUSTWORTHY or an Asymmetric Key.

Stairway to SQLCLR Level 3: Security (General and SAFE Assemblies)

In the third level of our Stairway to SQLCLR, we look at the various mechanisms in place to help us control Security. In this Level we will focus on SAFE mode and see how secure SQLCLR is by default.

Encrypt a file from SSIS using the Advanced Encryption Standard (AES)

This article demonstrates how to create a CLR assembly that can encrypt or decrypt a file with AES-256 cryptography, how to reference the CLR assembly from an SSIS script task, and how to generate an MD5 checksum file so that its recipient can confirm the integrity of the encrypted file.

Stairway to SQLCLR Level 1: What is SQLCLR?

The first step to using the SQLCLR begins with this overview of what is possible and what is not. Start your journey to decide if this is a tool you can use inside your SQL Server instance.

Relational database or graph database? Why not have both?

SQL Server may not be the best solution for every problem, but we have the means to extend its capabilities by linking it to external resources; in this case, using SQLCLR to query a graph database.

Exporting CLR Assemblies from SQL Server back to .dll files

You have imported an assembly into a SQL Server database to use the CLR functions and stored procedures it contains. However later, you lost the original .dll file and you would like to create the .dll file again from what's in the database. In this tip, we look at how you can recreate the .dll file.

Stairway to SQLCLR

The possibilities for programming SQL Server platform were greatly enhanced with the addition of the SQLCLR subsystem. This allows code written in any .NET language to be incorporated into your SQL Server instance and called from a stored procedure or function. You can also create your own data types or aggregates for specialized purposes. This Stairway series will teach you how to get started writing your own CLR code and integrating it into SQL Server.
