When you are developing an application, it is imperative that the user is able to use it even when there is no internet connection. To do this, you need to set database option offline to on. This article will show you how to do that in your SQL Server database.

When working with databases, we often have a situation where we are not connected to the internet or maybe our database server is down or any other reason that could prevent us from accessing the database. In such situations, we cannot access any data that is stored in our SQL Server database. However, the good news is that there is a way we can use our SQL Server even when it’s offline and this article will show you how to do just that!
Setting Database Option Offline To On For Database
Take Database Offline Rollback Immediate
By default, when you take a database offline in SQL Server, the transaction log is purged and the transaction log files are truncated. The database is then brought online. If your database was in full recovery mode at the time it was taken offline, the transaction log is not truncated because it will be needed by the database when it comes back online. You can take a database offline without truncating its transaction log by using the T-SQL statement ALTER DATABASE [database_name] SET OFFLINE IMMEDIATE.
Here are some of the common questions I have seen regarding taking databases offline:
How can I check which databases are currently taken offline in my SQL Server instance?
How do I know when a particular database has been taken offline?
How can I check who took a particular database offline? What is the date/time stamp?
SQL Server database offline means that the database is unavailable to users. It can be taken offline by either a user or a system administrator.
When you take a SQL Server database offline, the transaction log files are truncated, which means all transactions are lost and cannot be recovered. However, you can take the database online again after you have backed up your data and restored the transaction log files.
To take a database offline, use the ALTER DATABASE statement with the TEMPOFFSET option in SQL Server 2000 and above. If you want to check who made the database offline and when it was taken offline, use DBCC CLONEDATABASE (Transact-SQL).
In this article we will see how to take database offline in SQL Server.
Take Database Offline In SQL Server:
Step 1: Open SSMS and connect to your SQL server instance.
Step 2: Right click on your database and click Take Database Offline.
Step 3: Click Yes to confirm the operation.
You can take a database offline in SQL Server 2019, 2016, 2014 and 2012. You can also take an availability group database offline. This article explains how to take a database offline and what the difference is between taking a single database offline versus taking an entire availability group offline.
Take Database Offline
To take a database offline in SQL Server, do the following:
1) Right-click on your database and choose Tasks > Take Database Offline.
2) Click Yes to confirm your choice.
SQL Server Take Database Offline Taking Long Time
SQL Server take database offline rollback immediate:
When you take a database offline, this is known as the transaction log replay. A transaction log replay involves replaying all the transactions that took place in the log after the last checkpoint of the database. The transaction log replay is a very resource-intensive operation and can cause SQL Server to slow down significantly. This can be avoided by using the WITH ROLLBACK IMMEDIATE option. It rolls back any uncommitted transactions and makes the database available again right away.
How to check when a SQL database was taken offline?
To check when a SQL database was taken offline:
In Object Explorer right-click on your database name and select Properties from the context menu or use ALT + E + P keyboard shortcut
Click on Options tab
In Transaction Log section click on Open button
In Transaction Log file name box type TxLogFileName and click Check button

SqlTakeDatabaseOffline() is a function that can be used to take a database offline in SQL Server. It takes the database offline by removing the database from the set of available databases that are currently being hosted by the specified server instance.
The most common reason for taking a database offline is to fix problems with it, such as data corruption, or else upgrade it to a newer version of SQL Server.
The database is taken offline. SQL Server takes the database offline when you use the ALTER DATABASE statement with the TAKEOVER option. The TAKEOVER option allows a database to be mounted as long as it does not have any active users.
The database is offline and someone made it that way. When you run DBCC SHRINKFILE, SQL Server checks the status of each file in the database and determines whether it can be shrunk or not. If a file cannot be shrunk, it stays online and online backups continue to use this file until it is able to shrink (see How to: Shrink a Database File).
SQL Server Take Database Offline: Sql server take database offline can be a very useful feature for many reasons.
One of the most common uses is to free up some space on your SQL Server. Another is to do some maintenance on your database such as backup, restore or even index rebuild. In this article, we will look at how you can use the SQL server take database offline command and what steps need to be taken to bring the database back online.
If you are using an Availability Group then you can take one of the databases in that group offline without affecting any other databases in the group. The only time when this will not work is when all of the replicas are unavailable due to issues with their underlying storage subsystems (such as storage spaces). More detail on this topic can be found here: https://msdn.microsoft.com/en-us/library/ms173786(SQL.120).aspx
The process for taking a database offline involves:
1) Ensure that all users are detached from the database (this is important otherwise they might get stuck trying to access the database):
–SELECT name FROM sys.databases WHERE name = ‘AdventureWorks2012’;
When you take a database offline, the system works as follows:
The transaction log is truncated.
The database is put into the OFFLINE state.
The checkpoint process stops running.
All backups are suspended until the database is put back online.
You should use this option only when you want to perform maintenance on your database or server. While the database is offline, all data modifications are queued and not processed until after the database has been taken back online. You can use this option to perform maintenance tasks when no users are accessing your database or server, such as restoring a backup or upgrading software components that have been installed on the server.
How To Check When A SQL Database Was Taken Offline
You can use the sys.dm_server_registry stored procedure to determine when a SQL instance was last taken offline. The following example returns the date that each instance was last taken offline:
SELECT name, value FROM sys.dm_server_registry WHERE name = ‘ServerName’;
SQL Server takes a database offline when you perform maintenance activities such as restoring a database or running DBCC CHECKDB. You can also manually take a database offline. For example, if you want to perform tests on the data in a production database without impacting production users, you can take the database offline and then run your tests against that copy of the data while users continue to work against the production copy.
In this article I will show you how to take a SQL Server database offline using different options.
