75 days up time

And 75 days connected! Most stable router I’ve had had in the last seventeen years, also never had an internet connection this stable either. Well done to Billion, it wasn’t cheap mind, and to Zen.

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.

29th October 2017: Seems to have resolved the issue.

Cannot synchronise MLAT with Piaware?

Possibly an issue with Pi firmware of 4.9.x, find out your version by using this command

uname -a

If so then issue these commands, the first installs the firmware updater the second the 4.4.50 version of the firmware.

sudo apt-get install rpi-update
sudo rpi-update 52241088c1da59a359110d39c1875cda56496764

If you can’t install the firmware because you have a “custom” kernel then you’ll have to get the latest version of Raspbian and install that, then run the above two commands.

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)
