Hi (this is a revised version of a question I asked previously - hopefully made clearer).
I need to pivot a result set based on a range of dates (wherby the dates become the column headers). Prior to retrieving the data, the user would choose a range of dates working backwards e.g. 1st June 2012 to 15th May 2012.
I appreciate that varying the number dates in the result set will affect the number of columns when you pivot the data (which in itself might prevent the ability to pivot (but I don't know)).
If it's not possible to vary the number of columns, is it possible to always have a sliding window of 31 days i.e.
<user selected date> to <user selected date minus 31 days>
so that the number of columns remains the same.
I attach a small sample of data show how I need the pivot to occur. It only contains 2 days worth of data, but I hoping that whether its 2 days, 5 days or 30 days, the logic should be the same (the loop count would just grow).
