SQL SERVER – Remove Cached Login from SSMS Connect Dialog – SQL in Sixty Seconds #049

One of the most annoying thing which I have personally come across is drop down list of Server Lists on Connect dialog in SQL Server Management Studio. Here are two of the cases when I want to delete something from SSMS Connect Screen: 1) Incorrect server name typed 2) Server does not require in the future. When I see a name of the server which is there for a long time and I know that I am not going to use it, I feel like deleting it right away so I do not have to see it again.

In SQL Server 2008 and earlier version there was a file in the installation folder once deleted it would remove all the cached login from the Connect drop down of SQL Server Management Studio. Here is the direction for SQL Server 2008 and earlier version. However, in SQL Server 2012 product team has made it very easy for all of us. We can just select the connection name which we want to do remove and click on delete and it will immediately remove the entry. This way, instead of removing every single entry, you can pick and select the entry which you want to delete.

SQL SERVER – Enable SQLCMD Mode in SSMS – SQL in Sixty Seconds #048

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.

SQL SERVER – Resolve Cannot Resolve Collation Conflict Error – SQL in Sixty Seconds #047

One of the most common errors database developer’s receives when they start working with database where there are different collation used. Collation is a very important concept but it is often ignored. First use the method displayed in this video to resolve your error and right away put your efforts to understand what collation stands for.

Language is the most important part of communication. We all communicate with each other through language which both persons to understand. If we do not talk in the language which the other person cannot understand, the end result is not fruitful. In a similar way, collation is very important to any database. I have often seen situations when the collation changes from case sensitive and case insensitive turning the query result hey-wire and creates chaos on the server.

SQL SERVER – Shortcut to SELECT Single Row from Table – SQL in Sixty Seconds #046 – Video

Earlier I have blogged about the same subject and in very short time I received lots of good comments about this blog post as well lots of email from users who faced issues to make this work. Thought, the instructions are very simple in the blog post, every user read it differently and they have a different interpretation. I finally decided to do convert the same blog post in the video. I hope now it will be much easier to understand it.

If you watch any SQL Server Developer, you will notice one particular task them doing every day frequently. It is they select the row from the table to see what are the various kinds of data it contains. It is very cumbersome for developers to continuously write following code to retrieve a single row to see what the table contains. There is a shortcut how we can make our life easier if we use SQL Server Management Studio Shortcut. In this quick video we will see how we can create a shortcut which will select a single row from a table.

SQL SERVER – Cycle Clipboard Ring in SSMS – SQL in Sixty Seconds #045 – Video

Copy and Paste! In other words – CTRL + C and CTRL + V – these two are our famous shortcuts for this new age. Remember copy paste is not a bad thing but plagiarism is for sure. I rely on a lot of Copy Paste when I am doing development. There are so many templates, code or name of the objects (tables, stored procedure) etc which we need when we are doing development. If we keep on typing those names, there are chances of making human error which can lead to further problems.

Now the problem with the copy paste is that we can only paste one item which was the last copied. There are often scenarios when we want to paste more than one value without keep on going back again and again to copy them. I was very much delighted when I discovered the shortcut of the Cycle Clipboard Ring and Paste it.  However this shortcut is not very popular among developers – CTRL+SHIFT+V. I have created a short video which describes the same.

SQL SERVER – Restore SQL Database using SSMS – SQL in Sixty Seconds #044 – Video

“How do I restore my backup?”

I often receive this question from two kinds of users – i) who are panicking as they are not able to restore database ii) developers who have full backup but not sure how to restore it and use it.

In industry everywhere you go, everybody is taking backup but I noticed hardly anybody try to restore it. When users have not restored the backup for a long time, they have either no expertise to restore or have no idea if their backup have an issue while restoring.

Earlier I have created a SQL in Sixty Seconds Video on How to Take Backup of the database, in this video we learn how we can restore the same backup.
