| Good afternoon all,This is my first post so if a similar question has already been posted and answered please forgive my redundency. I have a table with the following columnsCL_ID DATE_REMOVED DATE_RETURNED NBR_OF_MOVES5 1/4/2000 1/10/2001 15 4/9/2004 9/2/2005 25 1/4/2006 5/17/2007 35 7/23/2008 NULL 4What I'm trying to do is create a SQL statement that will subtract the 'DATE_RETURNED' date from the next 'DATE_REMOVED' date. So essentially the results would look like the following:CL_ID DATE REMOVED CALCULATION 5 1/4/2000 (4/9/2004 - 1/10/2001) = 5 4/9/2004 (1/4/2006 - 9/2/2005) = 5 1/4/2006 (7/23/2008 - 5/17/2007) =I know how to subtract the dates, what I am having difficulty with is how to set up the query to do the actual subtraction if the table is set up this way. Any help would be much appreciated.~future |
