Remote Desktop: Map a local drive on the remote host

If you repeatedly use a Remote Desktop session and that session needs access to files on the machine you’re connecting from then you’d normally set up a network drive, possibly mapped as follows:

net use z: \\yourmachine\c$ /persistent:Yes

But, depending on how Draconian your network security is then mapping folders on user machines may actually be blocked. Strange one as this ability is mostly essential when working on a remote machine, especially if a developer. Fortunately you can map using the built in sharing of RDP. Same format as earlier just the machine name changes and effectively becomes a constant, so the mapping is now:

net use z: \\tsclient\c /persistent:Yes

And job done, until the next group policy is introduced blocking that…

Search an MS-SQL database for a specific named column

Need to find a column in a database? The following SQL will return the tables, and columns, that contain a wildcard value

SELECT c.name AS ColumnName,
       t.name AS TableName
FROM sys.columns c
JOIN sys.tables t
 ON c.object_id = t.object_id
WHERE c.name LIKE '%column_name%'
ORDER BY TableName,
         ColumnName;

Windows PC not auto-booting?

Since I installed the “Windows 10 Fall Creators Update”, build 16299, the desktop has stopped auto-starting, to it’s BIOS configured schedule. It’s scheduled for a 5:01am start, but every morning I’ve come into the room, since the update, it’s sitting there switched off.

A couple of Google’s later and here’s the answer, well I hope it is as I haven’t verified it yet, something for tomorrow morning. So the suggestion is to disable Windows “fast startup” mode, details on doing that can be found over at TechAdvisor.co.uk, and a more detailed explaination of why is at HowToGeek.com.

Transact SQL – (Global) script variables

Problem:

When running a SQL script using the command sqlcmd tool if you switch context to another database, by using the “use database” command, then any variables defined before this are lost. A similar thing happens if you use the “go” command to group, or batch, commands in the script.

Solution 1:

Create a temporary table, e.g

CREATE TABLE #GlobalVariables (variableOne varchar(30), variableTwo int)
INSERT INTO #GlobalVariables (variableOne, variableTwo) VALUES ('ABCdef', 222222)

Solution 2:

Use script variables

:setvar variableOne "ABCdef"
:setvar variableTwo 222222

To access these in your SQL code you would do the following:

UPDATE #GlobalVariables SET variableOne = '$(variableOne)', variableTwo = $(variableTwo)

Windows – using a local account with the free Windows 10 upgrade?

If so then, for the future, to enable you re-install Windows 10 you will need, before the free offer expires, to register your devices and their Digital Licences with your Microsoft Account.

If you already log into Windows 10 using your Microsoft Account then this has already happened and fresh installs will use that information when it comes to activating your Windows installation.
But if you haven’t then you need to do so ASAP, the free upgrade ends on the 29th July, 2016.

So if you use a local account to login then you need to go to Settings -> Update & security -> Activation and sign in with your Microsoft Account to associate that device and the Digital Licence

If you then want to auto login to Windows, without entering your password, then do the following:

  1. Press the Windows key & R, to bring up the run dialogue
  2. Enter netplwiz, and press enter
  3. Uncheck the “Users must enter a user name and password to use this computer” check box
  4. Click on “Apply”
  5. Enter your Windows account password, ignore the local user name displayed and do not enter the old password
  6. Reboot the PC, and all should be done
