Hi,
I came across a problem that I can't find a solution to and maybe one of you could help me with that.
I have a table that records Inventory on a nightly basis across our locations and it records any items that fall on zero stock.
I've to now show a count of 'days on zerostock' for items that has been on zero stock for any number of consecutive days.
Here is my sample table.
Company Item Qty Asof
US A 0 6/20/2013
US A 0 6/19/2013
US A 0 6/15/2013
US A 0 6/14/2013
US BB 0 6/20/2013
US BB 0 6/19/2013
MUC A 0 6/20/2013
MUC A 0 6/17/2013
MUC A 0 6/16/2013
MUC BB 0 6/19/2013
MUC BB 0 6/18/2013
MUC BB 0 6/17/2013
MUC BB 0 6/10/2013
The extra column needs to show values as per below. (Remember : Its by Item and by Company )
Company Item Qty Asof Days on Zerostock
US A 0 6/20/2013 2
US A 0 6/19/2013 1
US A 0 6/15/2013 2
US A 0 6/14/2013 1
US BB 0 6/20/2013 2
US BB 0 6/19/2013 1
MUC A 0 6/20/2013 1
MUC A 0 6/17/2013 2
MUC A 0 6/16/2013 1
MUC BB 0 6/19/2013 3
MUC BB 0 6/18/2013 2
MUC BB 0 6/17/2013 1
MUC BB 0 6/10/2013 1
Can you help me with providing a sql query of how to popluate this new column.
Any help is appreciated.
Thanks,
Devang.
