Um die Funktionen, die Microsoft SQL Server 2019 bietet, in Anspruch nehmen zu können, benötigt ein Anwender zwingend eine entsprechende Clientzugriffslizenz – z.B. die SQL Server 2019 Device CAL; diese enthält die Zugriffsrechte für ein einzelnes, registriertes Endgerät. Denn die SQL 2019 Serverlizenz für die Standard-Edition in der Server/CAL Variante enthält selbst keine Nutzerrechte, diese müssen separat z.B. in Form einer Zugriffslizenz für ein Endgerät (Device) erworben werden. Diese Device CAL gewährt jeweils nur dem damit ausgestatteten Computer die Erlaubnis zum Serverzugriff.

25x Device CALs for SQL Server 2019 as used software

In order to be able to make use of the functions offered by Microsoft SQL Server 2019, a user absolutely needs a corresponding client access license - e.g. the SQL Server 2019 Device CAL; this contains the access rights for twenty-five individual, registered end devices. This is because the SQL 2019 Server license for the Standard edition in the Server/CAL variant does not itself contain any user rights; these must be purchased separately, e.g. in the form of an access license for an end device. This Device CAL only grants permission for server access to the computer equipped with it.

As used software, SQL Server 2019 Device CALs from Wiresoft not only offer the great advantage that they are also available individually, but that they also have a lower price than comparable offers from the usual license providers. They have the same functionalities as the Device Client Access Licenses for SQL Server 2019 available through the official Microsoft Volume Licensing Program.

Get all the benefits of MS SQL Server 2019 with a pre-owned Device CAL

SQL Server 2019 is currently the latest version of Microsoft's database platform. Companies using enterprise resource planning systems, ERP software or CRM systems can use all the important database, reporting and analysis functions of this powerful relational database management system.

Depending on the edition, SQL Server 2019 includes, in addition to the possibility of clustering (group assignment) of data, monitoring functions for their systematic collection during the processing of targeted database queries. With the SQL Server 2019 Device CAL, users on a dedicated end device take advantage of all the benefits offered by Intelligent Query Processing for accelerated queries of larger data volumes, as well as the new Big Data Cluster feature with machine learning tools and PolyBase for optimized processing of Transact-SQL queries from external data sources.

Other SQL Server 2019 features:

  • Always Encrypted securely encrypts data - both of the client and the DBMS
  • Intelligent Query Processing optimizes queries of large data sets
  • Intelligent Performance provides faster execution speed for database operations
  • Database Snapshots document potential discrepancies
  • Last Query Plan Statistics provide up-to-date views of queries
  • lightweight Query Profiling Infrastructure enabled by default
  • Accelerated Database Recovery for faster recovery of databases after a restart or transaction rollback

Device CALs for SQL Server 2019 Standard edition

Even with a used Device CAL from Wiresoft, you can fully use the usual functionalities and services of SQL Server 2019 Standard-Edition: Small and medium-sized companies in particular benefit here from the licensing option per Server/CAL, which consists of the server license and a varying number of access licenses (Client Access Licenses) for devices.

Licensing model for SQL Server 2019 with server licenses plus CALs

The option of licensing a SQL Server 2019 plus Device CALs is done according to the terms defined by Microsoft - this licensing model is called Server/CAL licensing. Microsoft license management thus differentiates between licensing of the servers and that of the individual end devices or users. Each server on which an SQL Server instance is run first requires a Standard Server License 2019. To access the licensed SQL Server, a separate access license(Device CAL) of the identical or a higher server version is additionally required for each dedicated enddevice.

Only the Device CAL entitles the device to use the SQL Server functions of version 2019. A client access license for end devices does not contain any additional software that needs to be installed, but only the access rights in the client/server environment for SQL Server 2019.

For Device CALs to SQL Server 2019, version compatibility must be considered

A Device CAL for SQL Server 2019 also entitles access to SQL Server 2017 or an older version (downgrade). However, the reverse case of using the Device CAL of an older SQL Server version, such as 2016, to access a higher SQL Server version, such as 2019, is not possible. Therefore, you should make sure that you have the correct version of your Device CALs when using SQL Server 2019.

Why are there client access licenses for SQL Server 2019 Standard edition?

For the Standard-Edition of SQL Server 2019, Microsoft optionally offers CAL-based licensing for Devices (endpoints), among others. Server access licensing via Device CALs is more economical, especially for SMBs whose SQL Server has lower performance but is sufficient for their needs. For this type of SQL Server 2019 usage, the Microsoft licensing model offers two different types of CALs:

  • SQL Server 2019 Device CAL: this gives server access rights to a dedicated endpoint device (PC, Laptop, Table, Mobile)
  • SQL Server 2019 User CAL: this equips a dedicated user with server access rights

Buying, for example, multiple device client access licenses to use the SQL Server features is then usually cheaper than server licensing by cores.

What are the specifics of licensing with Device CALs for SQL Server 2019?

A Device CAL is a license that gives a specific end device (device) access rights to SQL Server 2019. It is not possible to subsequently change this end device specified during initial registration, nor is it possible to change the type of assignment - from Device to User CAL. These restrictions are intended to prevent misuse of CALs and offer greater security because unauthorized or foreign users cannot access a company's server.

What are the benefits of the Device CAL for SQL Server 2019?

In terms of functionality, there is essentially no difference between the endpoint-based client access license and that for users. The respective advantages are shown by the type of typical SQL Server accesses. Companies using SQL Server usually differ in the number or type of workstations used for common workflows: For example, in certain projects, several employees may share a single computer or use it in shifts, while in another work environment, the same user regularly uses completely different end devices to access the SQL Server.

By tying the device license for SQL Server 2019 exclusively to a specific Windows-enabled endpoint - rather than to a user to use the right to access SQL Server, different types of usage arise depending on the type: If it is a mobile end device such as a laptop, the respective user can access the SQL Server via it not only within the company, e.g. at the workplace, but also outside of it - e.g. at another company location or at home-Office. With a PC, access naturally always takes place at the same location.


So, which CAL type for SQL Server 2019 offers more deployment options in a given organization differs based on the predominant usage scenario. The decision for the type of client access licensing has to be made before the purchase, because as already mentioned, a Device CAL for SQL Server cannot be subsequently changed to a User CAL or vice versa.

Not only does the number of employees play a role, but also the main way in which the end devices are used: If many employees alternately use the same computer to access the SQL Server, no matter if internal or external or mobile, then licensing with Device CALs offers more advantages. Device CALs are therefore the suitable form of licensing as soon as several employees regularly access the SQL Server alternately via a single end device.

Buy Device CALs for Microsoft SQL Server 2019 from just one license in the Wiresoft Online Shop

Device CALs for SQL Server 2019 are available in the Wiresoft Online Shop from as little as a single user license - the offer as used software is significantly cheaper than a comparable new license, without the "used" condition of the CAL meaning any disadvantages in terms of usability, as software cannot wear out.

What are used Device CALs for SQL Server 2019?

The Device CALs for SQL Server 2019 offered in Wiresoft's online shop are original access licenses as available as part of the Microsoft licensing program; with the difference that they were once part of a volume license of SQL Server 2019 for endpoints purchased by a company that resold unneeded individual Device access licenses or the volume license to Wiresoft. This former volume license was broken up and converted to individual licenses, in the process the Device CALs were labeled as used software or Used Software. As already mentioned, this designation does not imply any wear and tear of the Device CAL software for SQL Server, nor does it imply any restriction in its functionality or its use for an unlimited period of time.

What kind of security do used Device CALs for SQL Server 2019 offer?

Buying used software such as Device CALs for SQL Server from Wiresoft is not only cheaper for customers, it is also secure! Because already a single Device CAL for Microsoft SQL Server 2019 you get not only at a cheaper price than the corresponding new software, but you also have buyer security through the instant download after payment plus license activation with the included volume license key.
