The sqlcmd utility is a command-line utility for ad hoc, interactive execution of Transact-SQL statements and scripts and for automating Transact-SQL scripting tasks. Often a developer believes that sqlcmd works with only command prompt, however that is not true. sqlcmd can also work with SQL Server Management Studio. There are lots of cool tricks we can do with sqlcmd while we are using it along with T-SQL.
One of the tricks which I often use it that I use it to connect to different servers from SQL Server Management Studio while I work with multiple SQL Server instances. This way I do not have to keep on connecting/disconnecting the server using SSMS prompt. This makes things very easy as well it is less distracting. The code which you can use to connect to another server is as follows:
SELECT @@SERVERNAME GO :Connect localhost SELECT @@SERVERNAME GO
In this SQL in Sixty Seconds video I have demonstrated how we can list Windows Directory while we are working with SSMS. The display of the SQLCMD is visible in the message area of the SSMS result pane. The code of the same is as follows:
USE AdventureWorks2012 GO SELECT DISTINCT Type FROM Sales.SpecialOffer; GO !!DIR GO SELECT ProductCategoryID, Name FROM Production.ProductCategory; GO
This trick is described over here.
