Hi, Recently I talked to a Microsoft official and he said SQL Express cannot be installed in any client site where there are more than 10 employees. Save my name, email, and website in this browser for the next time I comment. Toggle navigation. It runs as a local application—not as a service.
It supports all of primary programmability features as the other SQL Server relational databases, but there is no required configuration. It is not intended to support production or multi-user workloads. The installer is called SqlLocal. This edition is a good fit for small scale production databases, and is often distributed by different ISVs along with their applications. This version is best for developers who are creating and managing multiple small SQL Server databases.
This version is best for small application developers who need to include reporting capabilities with their applications. IF you try to install the Extended Security Updates update manually from catalogue it will fail to install. Also, please note, Extended Security Updates activated devices and non-Extended Security Updates activated devices can exist in the same computer group for patch deployment. Third-party application control solutions are not a replacement for product security fixes.
After January 14, , the first Extended Security Updates update date will align with the patch Tuesday date in February Azure does not currently support shared storage clustering.
You may apply this benefit even if the SKU is active, but note that the base rate will be applied from the time you select it in the portal. No credit will be issued retroactively. Visit the Azure Hybrid Benefit landing page to learn more. Today, we offer SQL Server customers with Software Assurance licence mobility benefits, which allows re-assignment of their licences to third party shared servers. This benefit can be used on unmanaged offerings in the cloud i.
Customers only get one core in the cloud for every core they own on-premises, and can only run in their specified edition, i. Standard can only run in Standard Edition in the cloud.
Moving your licences to a fully managed PaaS product. We are the only cloud that has this. Yes, Software Assurance is required for Licence Mobility. Azure Hybrid Benefit datasheet. Server and R2 end of support datasheet. Windows 7 end of support. Try on Azure. Download end of support datasheet.

What are the eligibility requirements for purchasing Extended Security Updates for use on-premises? What Azure services will Extended Security Updates apply to? Are there any changes to the type of updates in Extended Security Updates compared to Extended Security Updates? Are there any changes to the technical support options for Extended Security Updates customers since ?
General Questions. What does end of support mean? When will the Extended Security Updates offer be available? What do Extended Security Updates include? What licensing programmes are eligible for Extended Security Updates?
Are customers required to cover all on-premises servers with active Software Assurance to get Extended Security Updates on-premises? What are the details of the Extended Security Updates for on-premises?
Customers can choose which servers to be covered. Coverage will be available in three consecutive month increments following end of support. Can customers license just the virtual machine? For example, if a customer is running a Windows Server or R2 virtual machine on Windows Server or another host, do they need Extended Security Updates for the full server? Is there a deadline for when servers need to be migrated to Azure, or can customers wait until the end of support dates? Does this offer replace Premium Assurance?
If existing licences were bought with Software Assurance on Select or through a Microsoft Products and Services Agreement, can Extended Security Updates still be purchased under a different but eligible agreement?
What happens if Software Assurance is not renewed on time, or at all? Support questions for Extended Security Updates. Is technical support included when you purchase Extended Security Updates? What are the support expectations when requesting support for a product utilising Extended Security Updates? Will Microsoft help troubleshoot an issue that is not related to an extended security update when a customer purchases Extended Security Updates?
Can an organisation which purchases Extended Security Updates submit support incidents using its Unified or Premier Support agreements? How are customers able to get support? Can they submit tickets online using support. What is the support expectation if a customer encounters an issue that requires a new feature?
Is offline servicing available for operating system images covered by Extended Security Updates? How will Extended Security Updates be distributed? Core licenses are sold in packs of two a 2-pack of Core Licenses , and packs of 16 a pack of Core Licenses.
Each processor needs to be licensed with a minimum of eight cores four 2-pack Core Licenses. Each physical server, including single-processor servers, will need to be licensed with a minimum of 16 Core Licenses eight 2-pack of Core Licenses or one pack of Core Licenses.
Additional cores can then be licensed in increments of two cores one 2-pack of Core Licenses for servers with core densities higher than 8. Customers cannot license individual Windows Server virtual machines. They must license the full physical server.
Licensing requirements for Extended Security Updates on-premises align to the licensing requirements for the underlying Software Assurance coverage or subscription. Customers will only need to know their Windows Server license position for a given server, to know how many Extended Security Update licenses they need.
Customers who have covered all the underlying cores of the physical server with Windows Server Datacenter licenses should buy Extended Security Updates for the number of physical cores, irrespective of the number of VMs running on that physical server.
Customers who have covered all the underlying cores of the physical server with Windows Server Standard licenses should buy Extended Security Updates for the number of physical cores, but will only be licensed to run and update two virtual machines on the server.
Customers who wish to run and update more than two virtual machines on a server licensed with Windows Server Standard must re-license all of the physical cores on the server with both Windows Server Standard and Extended Security Updates for each additional pair of virtual machines. Microsoft will only produce updates which can be applied on the latest Service Pack. For customers who do not have Software Assurance, the alternative option to get access to Extended Security Updates is to migrate to Azure.
For variable workloads, we recommend that customers migrate on Azure via Pay-As-You-Go, which allows for scaling up or down at any time. For predictable workloads, we recommend that customers migrate to Azure via Server Subscription and Reserved Instances. Licenses and Software Assurance do not need to be on the same agreement. However, we recommend customers complete migration before the End of Support date so that they do not miss any Extended Security Updates.
If customers miss a year of Extended Security Updates coverage, they may buy coverage for previous years at the same time they buy coverage for a current period.
Yes, customers can start a new , R2, , or R2 instance on Azure and have access to Extended Security Updates. Customers who purchase Extended Security Updates for production servers may also apply those security updates to servers licensed under Visual Studio MSDN subscriptions at no additional cost. There is no limit to the number of MSDN servers a customer can cover.
Premium Assurance is no longer available, but we will honor the terms of Premium Assurance for customers who already purchased it. Software Assurance is required as a pre-requisite to Extended Security Updates. Extended Security Updates coverage is not required to be co-terminus with Software Assurance coverage, but customers must have at least one month of qualifying Software Assurance coverage remaining at the time a given year of Extended Security Updates coverage is purchased.
If they migrate to Azure, however, they can get support using their Azure Support Plan. When customers have purchased Extended Security Updates and have an existing support plan:. Scenario: Support Team will work to troubleshoot customer issue Response: Yes.
Scenario: Support Team will do a root cause analysis Response: No. This program covers only the named product and the components that shipped with it. Unless explicitly stated the scope of this program does not extend to any other products or tools that the customer may be running on or with the covered product.
No, customers must purchase Extended Security Updates separately. The cost of Extended Security Updates is not included in the price calculation of the Unified Support agreement. However, customers with Unified Support and Extended Security Updates can request technical support for the , R2, , or R2 servers covered by Extended Security Updates.
Onsite or proactive support will only be available to a customer if it is part of their Unified Support agreement. Yes, organizations which have purchased Extended Security Updates can submit support incidents using any Microsoft Support offering, including Unified and Premier Support. Microsoft Partners are also able to submit tickets on behalf of their customers as long as the customer has purchased Extended Security Updates, though Partners will need a support agreement in place to do so.
All customers must call Microsoft Support in order to place a request for a technical support incident. As we continue to work to fully automate the validation process, the tech routers will validate whether a customer purchased Extended Security Updates. Once the customer is validated, a case will be created and routed to the appropriate queue for technical support. Customers should provide their Enterprise Agreement number or full customer name for validation.
If an investigation determines that resolution requires product enhancement available in a recent release, then a request will be made to the customer to upgrade to a more recent release where the capability is already available. See online servicing for more details. Extended Security Updates are not supported in offline servicing mode. Applying Extended Security Updates in offline servicing mode will generate an error and updates will fail.
The Wsusscn2. The latest Wsusscn2. Windows Server: Customers can leverage existing on-premises license investments to save on Azure Virtual Machines. Pricing is based on per core pricing, based on the number of virtual cores in the hosted virtual machine, and subject to a minimum of 16 licenses per instance for Windows Server and four for SQL Server. Customers cannot apply them to non-covered databases or share them with hosters. The following describes pricing for Extended Security Updates in various hosted scenarios.
Azure Pricing: Cost included in standard virtual machine rate SA or subscription required? The Extended Security Updates offer does not include technical support. Customers can use existing support agreements for questions. Most of the time, the database engine uses the file location from the master database. Logical name is used to refer to the file in all T-SQL statements.
There can be up to 32, files in one database. Extents are basic unit in which space is allocated to tables and indexes. An extent is 8 contiguous pages or 64KB. Uniform extents are made up of only single object. Mixed extents are shared by up to eight objects. The size of the page is 8KB. The start of each page is 96 byte header used to store system information such as type of page, amount of free space on the page and object id of the object owning the page.
There are 9 types of data pages in SQL Server. The SQL Server transaction log operates logically as if the transaction log is a string of log records. Each log record contains the ID of the transaction that it belongs to. Log records for data modifications record either the logical operation performed or they record the before and after images of the modified data.
The before image is a copy of the data before the operation is performed; the after image is a copy of the data after the operation has been performed. Different types of operations are recorded in the transaction log.
Every data modification insert, update, or delete. This includes changes by system stored procedures or data definition language DDL statements to any table, including system tables. Rollback operations are also logged. Each transaction reserves space on the transaction log to make sure that enough log space exists to support a rollback that is caused by either an explicit rollback statement or if an error is encountered. This reserved space is freed when the transaction is completed.
The section of the log file from the first log record that must be present for a successful database-wide rollback to the last-written log record is called the active part of the log, or the active log. This is the section of the log required to a full recovery of the database.
No part of the active log can ever be truncated. Virtual log files have no fixed size, and there is no fixed number of virtual log files for a physical log file. The Database Engine chooses the size of the virtual log files dynamically while it is creating or extending log files. The Database Engine tries to maintain a small number of virtual files. The size or number of virtual log files cannot be configured or set by administrators.
If the log files grow to a large size because of many small increments, they will have many virtual log files.
This can slow down database startup and also log backup and restore operations. SQL Server uses a write-ahead log WAL , which guarantees that no data modifications are written to disk before the associated log record is written to disk.
This maintains the ACID properties for a transaction. This allows you to connect to and manage your SQL Server from a graphical interface instead of having to use the command line. In order to connect to a remote instance of an SQL Server, you will need this or similar software. It is used by Administrators, Developers, Testers, etc. Then click Enter. SQL Server Management Studio will be open up as shown in the following snapshot in either of the above method.
A login is a simple credential for accessing SQL Server. For example, you provide your username and password when logging on to Windows or even your e-mail account.
This username and password builds up the credentials. Therefore, credentials are simply a username and a password.
