Executing SQL Script from Command Line

Yes, It's more pretty your SQL Server Management Studio, because you can just go to "File" option, find there "Open" and click on "File..." to load a SQL file (.sql) to execute it without problems.

But, have you ever tried to do so with a file create by this tool being large enough to freeze it literally when you open it? Well, in this case there's no way to execute that file through the tool.

Therefore, here we are with a SQL Server command that will help us with this task. You just have to keep in mind the command: sqlcmd, simple right?.

Let's say that we have a SQL server called "MY_SERVER" and my SQL instance "MY_INSTANCE" installed there. What I need now is to execute the following script "my_large_script.sql" located at "D:\Test".

It's important to consider that this command use Windows authentication by default, so it's only required to put this line in any command prompt:

sqlcmd -S MY_SERVER\MY_INSTANCE  -i D:\Test\my_large_script.sql

However, if you are using SQL authentication it's neccesary to use your credential in this way:

sqlcmd -S MY_SERVER\MY_INSTANCE  -U domain\my_user -P my_password -i D:\Test\my_large_script.sql

That's all, have fun with your scripts.

I Need to Send an Automatic Email with Lotus Notes

Image
If you don't know, Lotus Notes is an email client used in a lot of companies around the world.

As you can image, I did this example on a Spanish version of Lotus Notes 8.5 but I will explain it clearly enough. The first step is getting yourself into the inbox, then select the "Create" menu item and inside of it, click on "Agent...". You will get a dialog box opened, in this we have the possibility of setting the rules for this agent. However, in this case we will only set "Trigger" option to "On schedule" with the "Weekly" frequency. Don't forget to push the "Schedule..." button to program the agent in the right way. After this, select "OK" and close the dialog bo...

Turn Horizontal Visio Swimlanes into Vertical Ones

Image
In one ocassion, a friend at work called me because she had a problem with Microsoft Visio , she was trying to draw a process flowchat but using swimlanes, this was not a problem until she realized that it would be better to use vertical swimlanes instead of horizontal ones.    But, when she tried to drag a vertical one it just put together to the previous swimlanes created before.  To avoid creating a new visio document and lost your work just go to 'Cross-Functional Flowchart' ribbon and select 'Orientation' and 'Vertical'.     And it's done, now you can work with vertical swimlanes or if you like it you can turn them back to horizontal ones.
