By default, databases created in Azure SQL Edge use the simple recovery model. This means that you can’t perform log backups on these databases.
Fortunately, you can change a database’s recovery model to full recovery mode, which will enable you to back up the logs.
By default, databases created with Azure SQL Edge use the simple recovery model. This means that you can’t perform log backups on these databases.
If you need to perform log backups on a database created with SQL Edge, you’ll need to change the recovery model of the database to either full or bulk logged.
This can be done with T-SQL with the ALTER DATABASE statement.
T-SQL includes a DATE_BUCKET() function that allows you to arrange data into groups that represent fixed intervals of time. It returns the datetime value that corresponds to the start of each datetime bucket, as defined by the arguments passed to the function.
As far as I’m aware, the DATE_BUCKET() function is only available in Azure SQL Edge at the time of this writing.
Update: DATE_BUCKET() was introduced in SQL Server 2022.
You can use the SUSER_ID() function to return the login identification number of the current user.
You can also use it to return the login ID of another user.
This is similar to returning the current login name, except here we’re returning the ID instead.
Occasionally you might find yourself in the situation where you need to get the name of the current workstation that’s connected to SQL Server.
For example, maybe you have a stored procedure that inserts data, and you want to record the name of the workstation that inserted the data.
In such cases, you can use the HOST_NAME() function.
This is not to be confused with getting the server name.
You can use the SWITCHOFFSET() function in SQL Server to change the time zone offset on a datetimeoffset value.
The function accepts two arguments; a datetimeoffset(n) value (or an expression that can be resolved to a datetimeoffset(n) value), and the new time zone.
In SQL Server, the REPLACE() function enables us to replace a string with another string. But what if you want to replace a list of characters with another list of characters?
The TRANSLATE() function might help.
In SQL Server, the OPENQUERY rowset function enables you to execute a pass-through query on a linked server.
OPENQUERY is commonly referenced in the FROM clause of a query as if it were a table, but it can also be referenced as the target table of an INSERT, UPDATE, or DELETE statement.
This article presents an example of using OPENQUERY to do an DELETE pass-through query.
There are several ways to get the language currently being used in SQL Server.
The language of the current session will often be the default language for the login, but this is not necessarily always the case. A user can change the current language during the session.
Also, some of SQL Server’s built-in functions accept an argument that allows you to specify a language for that specific query.
This article shows you how to return the language currently being used.
TSQL provides the DATEPART() function, which enables us to return the day of the year for a given date in SQL Server.
By “day of the year”, I mean the day number of the given year.
