quote delimited CSV output for SQL

Catagory: sql server · This Entry · Comment(0) · eMail entry · Google
sql server

when you output sql text manually creating CSV file output format, you may need to adjust for quote delimited data if that data contains your delimeter or line feeds.

this code snippet is for 'comma' delimited output.

SELECT
  CASE PATINDEX('%[,"\r\n]%', [MyColumnData])
  WHEN 0 THEN [MyColumnData] -- not found
  WHEN NULL THEN [MyColumnData] -- unknown
  ELSE '"' + REPLACE([MyColumnData],'"','""') + '"' -- encode data
END
AS [MyEncodedOutput]

sandisk sansa 8Gb usb drive mode

Catagory: electronics · This Entry · Comment(0) · eMail entry · Google

in some cases, windows may register the device as a "media player". in this mode you cannot view random files/folders like a normal storage device. this threw me off since on my laptop it registered as ordinary removable storage mode, whereas on my desktop it registered as a media player.

there is a setting on the unit to auto detect this mode (media player if capable?). however you can force the unit into storage mode and navigate the drive.

Go to Settings -> USB -> Choose MSC

esbar using webasto fuel pump?

Catagory: electronics · This Entry · Comment(1) · eMail entry · Google
electronics

the stock Webasto air top at-2000 fuel pump (12 volt) does not work in an Eberspacher (espar) D1LC. we measured the volume of fuel output using a procedure detailed on page 23 of the Espar installation troobleshooting & parts manual, by letting the pump expel fuel into a cup (shot glass) for 90 seconds. not having a proper measuring cup, we weighed the output on a suitable, sensitive scale for results.

output was 13.6 grams of diesel. average density of diesel listed at 0.85 kg/l, so that's 16 milliliters of fuel.

the espar manual states the fuel delivered in this startup cycle should be between 3.4ml and 4.65ml. so, much less. it was also clear after operating for a few minutes, that excess fuel was not being burned off and the unit was spewing smoke like mad.

so the pump output is too strong, waaay too much fuel. so i'm still looking for a proper esbar fuel pump (mfg. part: 25 1830 45 00 00), any tips?

on a curious note, the heater contains fairly advanced microprocessor, electronics, and sensors. they are reasonably well built and remarkably intelligent. i had not realized the level of sophistication these 'simple' heaters enjoy, it's pretty amazing. now, only if it worked. sigh.

card magnetic stripe?

Catagory: programming · This Entry · Comment(0) · eMail entry · Google

curiously enough, i discovered the magstripe on a credit card does not encode or obfuscate data (more than being a magnetic field with the equivalent of a bar code that is)... i just assumed it did. when you think about it, this is really the equivalent of peering at the front of the card --that's what you "see". i guess this makes sense. but i've also realized, card information is more vunerable than i hoped.

there are a number of well known, publish standards and specs.
this is the format i got scanning one of my cards:

;4111111111111111=1201=LAST/FIRST

IE8 'IE7' compatibility mode

you can tell IE8 to emulate IE7, if for some reason your page isn't rendering properly in the new brower. add this tag to the master page in your project to cover the whole site in one step.

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

When you go to (re) install sql server, you may get this error if you re-use the same instance name since the Reporting Services user data files are not deleted during uninstall and may contain valued user data.

Here's the message: Rule Reporting Services Catalog Temporary Database File Existence failed.

"The Reporting Services catalog temporary database file exists. Select a Reporting Services files-only mode installation."

2009 black rock city gps map

Catagory: black rock city · This Entry · Comment(4) · eMail entry · Google
black rock city

here's my version of black rock city, garmin gps street map for 2009. i've added items from there, gate road, confirmed porto-potties locations (not all placed yet), ranger and medical locations. i'll be updating as the city starts to take shape, check back for the latest.

this is a garmin formatted street vector map, you can use with most garmin gps models. upload the map using the sendmap.exe program, or copy the file to your memory card if you have a newer model with a memory card
