SQLCMD -- Part IV (set your favourite editor)

From my previous posts one can understand that it is possible to write SQL queries directly in command prompt with the help of SQLCMD utility.

Now let's assume we have typed a 'big' query and there is a typo there! Instead of going back and forth to edit it in command prompt won't it be easy if we are able to open the query in an editor and make the corrections there?

Yes its possible in SQLCMD. All we need to do is type ed and it will open up the last command/query in a text editor. FYI the default editor is Edit (the command line editor of MS DOS).

Step 1: Open up SQLCMD and connect to your SQLServer
Step 2: type any query of your choice
Step 3: type ed
Step 4: The query would have opened in the 'EDIT' utility of DOS. Once you are done with the change, save and exit from that.
Step 5: type go and press enter

Can I make 'ed' to open up notepad or any editor of my choice?
Yes it's possible.

Step 1: Open DOS prompt
Step 2: Type set sqlcmdeditor=notepad
Step 3: Open up SQLCMD and connect to your SQLServer
Step 4: type any query of your choice
Step 5: type ed
Step 6: The query would get opened in notepad. Once you are done with the change, save and exit from that.
Step 5: type go and press enter

Script table as - ALTER TO is greyed out - SQL SERVER

One of my office colleague recently asked me why we are not able to generate ALTER Table script from SSMS. If we right click on the table and choose "Script Table As" ALTER To option would be disabled or Greyed out. Is it a bug? No it isn't a bug. ALTER To is there to be used for generating modified script of Stored Procedure, Functions, Views, Triggers etc., and NOT for Tables. For generating ALTER Table script there is an work around. Right click on the table, choose "Modify" and enter into the design mode. Make what ever changes you want to make and WITHOUT saving it right click anywhere on the top half of the window (above Column properties) and choose "Generate Change Script". Please be advised that SQL Server would drop actually create a new table with modifications, move the data from the old table into it and then drop the old table. Sounds simple but assume you have a very large table for which you want to do this! Then it woul

AWS fatal error: An error occurred (400) when calling the HeadObject operation: Bad Request

While using AWS and trying to copy a file from a S3 bucket to my EC2 instance ended up with this error message. Command Used: aws s3 cp s3://mybucketname/myfilename.html /var/www/html/ Error: fatal error: An error occurred (400) when calling the HeadObject operation: Bad Request The error goes off if we add the region information to the command statement.

[Non Tech] Want to know the recipe for Omelette :)

Fed up with Bread - Jam and Curd Rice, today i wanted to eat Omelette. Interesting part is I wanted to cook it myself :) So in the first picture you see all the items which are needed for preparing an Omelette. When I had a closer look at the eggs I see that almost all the eggs are broken. But believe me when I bought it couple of days back it was in perfect condition! I was wondering whether the eggs have become rotten or pretty old to consume! I tried taking an egg and break it but couldn't break it at all :) Since I have kept in the freezer all the eggs have frozen and looked like a iron ball :) After trying for few minutes of trying i removed the shell of the egg and then kept that iron ball :) into a bowl and placed it within Oven. I heated it for 1 minute and checked. It melted only to a limit. So i just set it for another 2 minutes and checked it later. It has melted but the part of the egg white has become a Omelette :( I didn't leave it there. I took the bowl out of
