Basically I have a table filled with wavelength and power readings from an optical sensor (sensor is being read every 15 mins) which I'm using to create graphs in Labview.
Plotting a full table takes a ton of time though, so I'm basically in need of a function that displays every 4th entry.
Now my SQL "skill" is crap to say the least, yet I figured "how hard could it be?" and had a go at it. I failed misearbly; 3 hours later and not a single usefull line of code later, I'm turning to you lot.
the main problem is is that the ID of the row doesn't have anything to do with where it is located.
ID Data
5 -60.0dB <-- entry 1
33 -58.3dB <-- entry 2
48 -59-2dB <-- entry 3
55 -58.6dB <-- entry 4
only entry 4 needs to be displayed :/
anyone here who has an idea how to do this?
