running-total

I have a table in an Oracle db that has the following fields of interest: Location, Product, Date, Amount. I would like to write a query that would get a running total of amount by Location, Product, and Date. I put an example table below of what I would like the results to be. I can get a running total but I can't get it to reset when I reach a new Location/Product. This is the code I have thus far, any help would be much appreciated, I have a feeling this is a simple fix. select a.*, sum(Amount) over (order by Location, Product, Date) as Running_Amt from Example_Table a +----------+---------

From the EMPLOYEE table, I want to group the amount of records(employees hired) AND also have the running TOTAL per day. The format of the input is like this: rownum Hired_date_time 1 1/10/2012 11:00 2 1/10/2012 13:00 3 20/11/2012 10:00 4 20/11/2012 15:00 5 20/11/2012 16:00 6 30/12/2012 1:00 The desired output: Hired_date.......Hired_per_day.........TOTAL_number_of_employees 1/10/2012 ...................2 ........2 20/11/2012 ..................3 ........5 30/12/2012 ..................1 ....... 6 No problem for the GROUPING PER DAY: select trunc(Hired_date_time) as "Hired_date" , count(*) as

I am trying to select the first n rowid values from the following table variable that will get me as close to a sum(itemcount) of 200,000 without crossing that threshhold. If I was looking at this manually, I would just take the top 3 rows. I do not want to use a cursor unless there is no pure-set-based way. What is a good set-based way to get all of the rowid values "sum while/until" I get to a running total of 200,000? I looked at "running totals" at http://www.1keydata.com/sql/sql-running-totals.html but that did not seem like it would work out because the real table has around 500k rows.

I have a table which contains the following data: ID In Out 1 100.00 0.00 2 10.00 0.00 3 0.00 70.00 4 5.00 0.00 5 0.00 60.00 6 20.00 0.00 Now I need a query which gives me the following result: ID In Out Balance 1 100.00 0.00 100.00 2 10.00 0.00 110.00 3 0.00 70.00 40.00 4 5.00 0.00 45.00 5 0.00 60.00 -15.00 6 20.00 0.00 5.00 Is it possible to do this with one query, without using a trigger or stored procedures? Short answer, yes Longer answer, you can use a variable to tally it up as it iterates down the rows, i.e. SELECT `table`.`ID`, `table`.`In`, `table`.`Out`, @Balance := @Balance +

I have a table like this (Oracle, 10) Account Bookdate Amount 1 20080101 100 1 20080102 101 2 20080102 200 1 20080103 -200 ... What I need is new table grouped by Account order by Account asc and Bookdate asc with a running total field, like this: Account Bookdate Amount Running_total 1 20080101 100 100 1 20080102 101 201 1 20080103 -200 1 2 20080102 200 200 ... Is there a simple way to do it? Thanks in advance. Do you really need the extra table? You can get that data you need with a simple query, which you can obviously create as a view if you want it to appear like a table. This will get

I have a table of the form Category Time Qty A 1 20 B 2 3 A 3 43 A 4 20 B 5 25 I need a running total to be calculated by category in MySQL. The result would look something like this: Category Time Qty Cat.Total A 1 20 20 B 2 3 3 A 3 43 63 A 4 20 83 B 5 25 28 Any idea how I could do this efficiently in MySQL? I have searched far and wide, but all I can find is info on how to insert one single running total in MySQL. I wonder if there's any way to use GROUP BY or a similar construct to achieve this. You could calculate the sum in a subquery: select Category , Time , Qty , ( select sum(Qty) from
