Queries :: Subtracting Rows In Access

Dec 8, 2013

I have a query with years and sales column. I need to make a column that displays the difference in sales between years. My query is named "Qry" if that is needed. "Year" and "Sales" are the column titles if you need that for the SQL.

Adding/Subtracting Across Adjacent Table Rows

Oct 30, 2006

Is it possible to perform calculations across 2 adjacent rows in SQL?

At the moment, I have a running count that tracks the number of updates that go into our database against a specific JobID.

Is it possible to subtract the running count for a previous update from the current update.

For example, I would like my resulting table to end up looking like this

JobID Time Updates Since Last Update
1 10:10:00 1 1
1 10:30:45 3 2
1 11:15:10 9 6

In this example, the Since Last Updates should be found by
subtracting the Updates at 10:10:00 from the Updates at 10:30:45 giving 2 and the Updates at 10:30:45 from 11:15:10 giving 6. It would continue like this for as many rows of data have the same JobID (which could be several hundred!)

What I would then like to do is use the 'Since Last Update' number to display only those updates that are applicable to a certain Time, perhaps using Select Top in SQL.

Am I approaching this from the right direction, or would it perhaps be better to try to do this using Time, as this will always be unique?

Thanks for looking

Queries :: Access 2007 - Merge Two Rows Into One

Apr 26, 2013

I am creating a query to use in a Word 2007 mail merge.

For simplicity, let's say the query has three fields:

schname for school name, role for staff role, and name for the staff member's name.

The current query shows:

SchoolA, Admin, Jerry Garcia
SchoolA, President, Bob Hope
SchoolB, Admin, Janet Jackson
SchoolB, President, Mae West

I would like a query that would show one line per school like so:

SchoolA, Jerry Garcia, Bob Hope
SchoolB, Janet Jackson, Mae West

I've looked at Allen Browne's ConCatRelated function and can pull up a list of all names in a field called Expr1001, but that doesn't seem to be what I need.

Subtracting Results From Two Different Queries.

Jun 16, 2005

Hi, here's the situation:

I have a query A, that gives me the a set of numbers.
I have a query B, that gives me another set of numbers.

Numbers in B are always equal or larger than those in A. (B >= A)

I want to create a new query C, that does the subtraction. (C = B-A)

Here's an example to explain what I want.
Let's say I have A=4,7 and B=6,9

Now, when I create the query, I get the following result:
A | B | C=B-A
4 | 6 | 2
4 | 9 | 5
7 | 6 | -1
7 | 9 | 2

What I want is this:
A | B | C=B-A
4 | 6 | 2
7 | 9 | 2

How do I do that?

Subtracting Dates In Queries

Feb 1, 2013

My form consists of a textbox with a selected date. I have a combo box with integers 1-15. I have a table with 15 people and their birthdays.

I am trying to find the birthdays after a selected date by the integer selected in the combo box. For example, if I select 2/1/2013, and pick 7 in the combo box, the subform should show me people with birthdays 2/1 through 2/8.

I have a query with a datediff function. This is my query expression Expr1: DateDiff("d",[DateofBirth],[Forms]![Calendar]![Text1]) The criteria is <=[Forms]![Calendar]![Combo3].

It displays some data, but it's not consistent at all. I'm hoping to fix this without any SQL changes or form code. But if that's what I need, I'll do it.

I'm using access 2010, and I'm fairly new at it.

Queries :: Concatenating Multiple Rows In Access 2010

Feb 11, 2015

I have a query that has multiple IDs and different information in numerous fields. For example:

ID Field1 Field2 Field3
1 x
1 m
1 b

I need to find a way to concatenate the data so that it shows the information like this:

ID Field1 Field2 Field3
1 x m b

I'm working in Access 2010.

Yes I know this isn't the best way to set up a database, but I'm trying to make fixes to an already existing database that I can't go back and change the way it is set up. I can only find work arounds to accomplish what I need.

Queries :: Subtracting Date Fields

Jul 10, 2013

I have an Access query which has 2 fields 'Sent Date' and 'Return Date'. Sent date is input by the user when they return an item for repair, return date is input by the user when the item is sent back to us from repair. What I need is a 3rd calculated field which will work out the number of days the item was away for repair. I have included the 3rd column 'Repair Duration' but I don't know how to type the formula in the query to work this out.

Queries :: Subtracting Stock Numbers With A Query

Jan 2, 2015

I'm creating a sales system that allows customers to place orders using a customer account. when a customer completes an order the number items in the order needs to be subtracted from the stock numbers of each of those items stored in the system.

What I have so far is zipped and attached,

The way my system works should be easy enough to understand, there are four linked tables that store information on customers, products and orders. What I'm really struggling to understand is how to take the values in the records in the Invoice-Product table and take them away from the stock numbers for the products in the products table. But only new orders should take away from the stock number when a new order is placed.

If possible I also need to be able to add stock numbers for example if a delivery comes in, and if it's similar enough could that also be done here?

Queries :: Sum Different Rows

May 3, 2013

I'm building a Bradford Scoring DB, everything is running smoothly apart from one niggle I would really like to get around and automate.Essentially, I'm hoping to run a difference sum query which is fine when it's on the same row, but the issue I'm having is that I'm trying to calculate this from another row, linked by name. This inturn will workout the difference between the two absence episodes i.e. it's been 80 days since their last absence end.

I did find a method which would view the previous AutoID, but this worked well for the whole table, but not within a query limited to name.The obvious workaround is to allow the team leaders to enter this manually, but this could be a/ open to small errors b/ mildly time consumingI, like most, work with people who want info NOW and with little effort.

Queries :: Select All Rows Except Last

Jan 22, 2015

How I might select all the records within a query except for the most recent one? I have an AutoNumber ID field and a date stamp to use , but I can't figure out how to exclude just the biggest record.I am trying to run an update query on the After Insert Event, so that when the user inserts a new record it will mark down similar older records as 'superceded'.

At the moment I can select all the records, and I can select just the largest one, but I can't seem to take one away form the other. Here is the SQL in it's current state:


UPDATE [Personnel-Qualifications] SET [Personnel-Qualifications].[Superceded?] = True
WHERE ((([Personnel-Qualifications].PersonnelID)=[Forms]![Personnel]![PersonnelID]) AND (([Personnel-Qualifications].QualificationID)=[Forms]![Personnel]![Child21]![qualificationID]));

Queries :: Rows To Columns

Mar 26, 2013

I have the following scenario and do not wish to use a crosstab for various reasons. I am combining three queries into one. The last query has information as follows:

Project Type Rev Budget
12345 Debt 100,000
23456 Impact 50,000
34567 Other 25,000

There are hundreds of these line items. The first two queries hold the project information as well and that would be the field that I would use to join each query. Currently the information above is in line form and I need to put it in column form to coincide with my other data. The final result needs to have the following column headings:

Project, Desc, Exp Budget, Expenses, Debt, Impact, Other, Rev Budget

Please note that the first four headings come from the first two queries so I have this taken care of. how do I change the query to put the Type by line item as a column heading and sum the Rev Budget accordingly without creating a table and doing appends or update queries? Can it be done in the query where I am combining the three queries?

Queries :: Combining Rows Into One Field

May 12, 2013

So in my example you have a Weld (tblWelding_WeldingID) and each weld can have more than 1 consumable (tblconsumables_consumableID). have a third table that links the two, trackID,consumableID, weldingID)

What I need to be able to do in a report, is under the heading COnsumable, list the 1 or many consumables.

Also you select the consumable from a combo box..... if that just makes it that much harder...

Queries :: Concatenate Multiple Rows Without VBA

Sep 23, 2014

I am trying to concatenate multiple rows into one record. I googled it and found many functions in VBA that do the job. However my problem is that my query will be linked directly to Excel file and then I get an error message saying that Excel could not recognise this function. I could potentially insert data into new table and link that table to Excel but I need to avoid end-user exposure to Access as much as possible.

So I am desperately trying to find a way of doing this without VBA code.

Example of data:

Customer Name |Order Number
Smith |O101
Brown |O102
Smith |O103
Green |O104
Brown |O105

I am trying to achieve below:

Customer Name |Order Number
Smith |O101, O103
Brown |O102, O105
Green |O104

Queries :: Counting Rows Within A Query

Apr 16, 2013

I am trying to get a total count of rows from a query on my tickets, Each ticket has a date and an ID number

SELECT tbl_ticket.ticket, tbl_ticket.entrydate, Count(tbl_ticket.[entrydate]) AS [Row Count]
FROM tbl_ticket
GROUP BY tbl_ticket.ticket, tbl_ticket.entrydate
HAVING (((tbl_ticket.entrydate) Between #1/1/2011# And #1/31/2011#));

I am trying to get this query built so I can attach it to a form.

I am trying to get three bits of data from this Query

1 a total count of all the Tickets in a given month

The ticket #'s and their date of entry.

So far this gives me a great list of Tickets and the date they got put in the system, but then for the total count it gives me 1 for each line. Even if some have the same date.

Queries :: Add New Rows Depending On Entered Value

Nov 12, 2013

I have a form where we fill in information for supply of PPE to employees.

Each item must be signed for on a printed report.

I am encountering problems trying to create enough rows for my report detail for each signature of the number of items supplied.

For example, on the form I will select the "equipment" - 4 hats supplied and 3 boots. On the report I want the equipment set as the group and the detail to be a number or rows which equals the number of selected items. therefore under the Hats group heading I want 4 blank rows which are made up of 3 text boxes - Print Name, Signature & Date and another group heading for boots but with 3 lines.

The Query gives the results below: (Item name is linked to a PPE table containing Item ID, Item Name, Cost etc..)

IssueIDDateProvidedItem_Name AmountIssued
0001 01/11/2013 Gloves (Orange) 10
0001 01/11/2013 Hard Hats (Black) 2
0002 02/11/2013 Hi Viz (Large) 5

The report I aim to generate from this should look as attached ...

The query/report is set up as a parameter report so I will enter the issueID such as 0001 and only those items will appear on the report to print and sign.
