Get The Difference Between 2 Rows Of Same Column

Aug 15, 2006

i have a table that has meter readings for copiers on it and dates.
i need to add another column to show the differences in the meter field between itself and the row entered before it (the month before) to find out how many copies were made. i can do this in excel very easily, but cant figure out how i would do it in access
sample:
Date Meter Diff.
06/01/2006 0 0
07/01/2006 1000 1000
08/01/2006 1500 500
we will be entering the date and the meters in every month, but i need to have it calculate the difference between months so i can then calculate overage, if any.

1205972 Jones 6/28/2013 Warfarin 7/6/2013 1.0 6.5 mg 29 138

[code]....

What I really want is to calculate the time (# day) it takes to reach a target goal INR (2-3) I have tried DateDiff between DOA (date of admission) and Start date but this obvious won’t work because some patient won’t start on warfarin until later.

Another possibility is to calculate date difference between two rows in same column but I don’t know how For example Pt 1 = It take 7 days to reach an INR of 2, Patient #2 = it takes 5 days to reach an INR 2.2 and Patient #3 takes 6 days to reach an INR of 2.1. Average = 6 days.

Queries :: Difference Between Rows - How To Extract CHANGED Value In A Column

Jan 24, 2015

I have a query question . How can I extract a CHANGED value" in a column? Example here under table1. Time and TAG makes a record unique, No ID available ...

Table1
time tag value
10:02 Tag1 10
10:02 Tag2 11
10:03 Tag1 10
10:03 Tag2 11
10:04 Tag1 10
10:04 Tag2 12
10:05 Tag1 10
10:05 Tag2 12
10:06 Tag1 10
10:06 Tag2 12
10:07 Tag1 11
10:07 Tag2 12
10:08 Tag1 11
10:08 Tag2 11

I want to have as output
10:04 Tag2 12
10:07 Tag1 11
10:08 Tag2 11
(so at 10:04 tag 2 changed in value and on 10:07 tag1 changed value and 10:08 changed Tag2)

Preferably with the previous value as well, but this is not the highest prio
10:04 Tag2 12 11
10:07 Tag1 11 10
10:08 Tag2 11 12

Calculating Difference Between Dates In Different Rows

Nov 18, 2011

I currently have a table that has patient ID (unique record (SSN)) and a date of visit field. The SSN may have numerous rows with different dates of visits. What I am trying to do is a DateDiff function that will retrieve records that are 48 hours apart or 2 days apart. We are tracking patients that return within 48 hours of a previous visit.

Queries :: Calculating Difference Between Dates In 2 Rows

Oct 25, 2013

I have a list of client activity - client name, loan ID and loan date. I would like to create a new field that shows the number of days between one loan and the next. If I was doing it in excel, I would need to sort the data by client name and loan date and then calculate the number of days between the loan date of one loan and the loan date of the loan immediately prior to this.

Column Difference From Same Table

Jul 11, 2005

I have a table that contains a significant amount of data. The columns are as follows;

ID, WeekNo, Ref, Cost

What I want a query to do is only show me differences in Cost value where the Ref is the same

For example

ID, WeekNo, Ref, Cost
1, 1, ABC, 123
2, 1, DEF, 456
3, 2, ABC, 123
4, 2, DEF, 789

The query I would like, would only show me the result of Rows 2 & 4 because the value of cost is different between the weeks.

At the moment I have two queries, One that pulls out the last weeks value (WeekNo 1), and the other that pulls out the same information but for the comparison week (WeekNo 2). In the third query I created I linked the two columns from the Ref fields, but could not work the logic to only show me ones where the differences in cost were displayed.

Thanks in advance of the resolution to this. I know it is basic query work, but just have a logical block in getting it to work.

Regards

Column Values To Rows?

Aug 25, 2006

I am trying to devise a way to display query results in a row instead of a column. The table on which the query is built has this structure:

Column1: Index (pkf)
Column2: Group (int)
Column3: Position (int)
Column3: ItemCode (txt)

When I do a select query, the data comes back like this:

Group Position ItemCode
11A
12B
13C
14D
15E
16F
Etc.

I want to arrange the data this way:

1ABCDE (Etc)

I keep thinking that a cross-tab query is the answer, but all I seem to be able to do is to get counts of Position 1, 2, 3 Etc.

I’m baffled. Does anyone have a suggestion?

Thanks,

Rick

Moving Column Data To Rows

Dec 21, 2011

I have an Excel sheet with data organized like:

1 A
1 B
2 A
2 B
2 C

I want to reduce the first column to unique records, and have the second column listed on the same row. (I'm assuming I'll need Access to do it.) Is there a way to produce a table like this?

1 A B
2 A B C

The final result would need to be something I could put back into Excel.

Queries :: Match Multiple Rows From Same Column

Apr 2, 2014

I have parent-child one to many data in one pair of relationships, and now I've been asked to see be able to find out what matches a defined regimen; each is also defined in a parent-child relationship.

Best is to show sample data. I'm going to show them as two tables, but the "Components" are actually in a parent-child relationship, e.g.,

PersonList -= Meds
Regimen -= Meds as well

Note that PersonList and Regimen do not really have any relation; we just want to see if things are being done one of the ways they are "supposed" to be done, without a slow manual check. It's worked as set up for reports, and I really don't want to change everything to a big long list of fields, one field per med for a lot of reasons (not least of which is that is denormalizing)

Quy 1 Result:
PersList T1Component
Andrew Med 1
Andrew Med 2
Brett Med 1
Brett Med 3
Brett Med 4
Charles Med 2
Duane Med 1
Duane Med 4

Quy 2 Result
Regimen T2Component
Goody1 Med 1
Goody1 Med 3
Goody1 Med 4
Goody2 Med 1
Goody2 Med 2

I'd like to be able to do two queries - one that are "OK" one that are not. Don't need to replicate the med list, just the regimen if matching..

"Good" would return
Person Regimen
Andrew Goody2 (he has med 1, 3, and 4)
Brett Goody1 (he has med 1 and 2)

"Bad" would return
Person
Charles
Duane

What they "almost match" does not matter; it tells people which ones we need to check into a bit more.

Update Average From Different Rows In One Column To Another Row In The Same Table

Aug 2, 2012

I am still quite new to Access and have spend the last two days looking for a solution to an issue but don't seem to find anything that fits. The problem is that I want the three year average of [NIbyA] inserted in [AvgNIbyA]. The years are stored in [FocalYear] (as Date/Time formate) and [TextYear] (as text formate) and [ID] indicates which entity the record belongs to (see below).

UniqueID
ID
TextYear
FocalYear
NIbyA
AvgNIbyA
1020180-19981231
1020180
19981231

[Code]...

Example.accdb

I have been playing around with update queries but can not seem to get the syntax right. The query needs to add NIbyA for year 1998, 1999 and 2000, divide it by 3 (or use Avg() function or something of that sort) and insert the result into the row where [FocalYear] = 13/12/2000. To add to the confusion, it should obviously only add those records that belong to the same ID. Years are from 1998 to 2010 and ID's are random (this obviously means that the rows where [FocalYear] = 13/12/1998 and [FocalYear] = 13/12/1999 will not have an entry).

How To Split Up One Column With Multiple Rows Related To One Person Into A Query

Jul 1, 2013

I have an Access Database and I want to split up one column into multiple columns. The one column has multiple rows that relate to one person, so for instance I have the following:I am taking information from both tables and I want to create a query but I need to separate out the mother, father, and guardian with the names attached

So from the Child table :

Joe Smith Address Phone

The query that I created is from two tables, the child table and the family table: ( I used the dashes just for it to be easier to read)

------Child Table/PrimaryKey --------Family Table---------------------

First Name--- Last Name--- First Name--- Last Name--- Relationship
Joe ----------------Smith ----------Jane --------Doe-------------Mother
Joe ----------------Smith ----------John---------Smith---------- Father

So in this scenario I need to get the name of the second parent in another column....meaning have all the parents appear on the same line for this child, and each child there after..

So I need it to look like this:

------Child Table/PrimaryKey --------Family Table---------------------

First Name------ Last Name------ First Name------ Last Name------ Relationship------ 2First Name------2Last Name------2Relationship
Joe----------------Smith------------ Jane-------------- Doe------------- Mother-----------John---------------- Smith------------ Father

Combining 2 Query Columns Into 1 Column With Data In Separate Rows

Mar 29, 2012

I have a database with all the hours employees have logged stored in the database. Our payroll company wants an excel spreadsheet that has very specific info in particular columns and fields on the excel spreadsheet, so I'm trying to design a query which will put the correct info in the correct fields per their system.

The challenge is, I have currently a query with Employee ID, Overtime Hours, and Regular Hours as separate columns.

I need to translate this to a query with a single column for hours and a separate column that designates those hours as OT or Reg, with two rows for those employees who have both types.

Current:

ID / Regular Hours / OT Hours
101 / 70 / 7.5
102 / 30 / 0
103 / 5 / 0

Needed:

ID/ Hours / Type
101 / 70 / Reg
101 / 7.5 / OT
102 / 30 / Reg
103 / 5 / Reg

I don't know how to create a query or a formula in a query to break out each employee row into multiple rows with different data in the hours column. It seems like there's something pretty straightforward that I've done in a similar vein but it doesn't seem to work - I can do the opposite and combine those hours by using the SUM function in a query, but I can't seem to break it out this way.

Access 2007, Windows 7.

I'm just wondering if there's any way I can do this with a datasheet or a crosstab type setup?

Compare Several Hundred Rows Against Other Rows

Nov 21, 2005

Not sure if what I want to do is possible, or at least possible the way things are set up.

I have a massive table - c. 6 million rows. It contains data along these lines:

Plan#, Item, Price, Description, Colour, Value, Location, etc.

The primary key would be Plan# + Item. Each Plan# has approximately 1,000 Items, and there is only 1 Item per Plan#. There are only a limited number of Items (c. 1500) and all or only some Items might be assigned to the Plan#. All items under each unique ID# belong together, sort of in a set. So this huge table has approx. 6,000 unique sets (based on Plan#).

To add to the confusion, Item A under Plan#1 may have different information (Price, Description, Colour, etc.) from Item A under Plan#2. I know this isn't a great way to set up data but this is what I have to work with.

Over the years it's possible that the exact same combination of Items with identical values might have been set up for multiple Plan#s. What I need to do is find any Plan#s which have the exact same combination of Item, Price, Description, etc. So if Plan#R has 200 rows and Plan#S has 201 rows, it automatically doesn't match. If Plan#R has 200 rows and so does Plan#T, all information in each record must match between the two Plan#s (with the exception obviously of Plan#).

I don't think this is possible, and if it is I am sure it's not going to be easy. So far the best I can do is to come up with finding duplicates on Item, Price, Description, etc. but that's only one record at a time and doesn't tell me if the two Plan#s match.

Any help or suggestions would be much appreciated.

Thanks!!!

Populating A Column In A Table Based On Values In An Existing Column

Mar 5, 2007

Hi all,

In the organisation that I work for employees get paid every 2 weeks on a Saturday. So for this financial year the pay period end dates have been 08/07/2006, 22/07/2006, 05/08/2006 etc


I have a column in an Access table listing various dates. I want the next column to be
populated with the next pay period end date after that date.

So if DATE is 05/07/2006 I want PAY PERIOD END to be 08/07/2006
and if DATE is 09/07/2006 I want PAY PERIOD END to be 22/07/2006 etc

How do I do this?

Kind Regards,

Matthew

Queries :: Change In Column Based On Base Query Column

I have created a cross tab to extract pipeline and sales for Q1 2014, Q2 2014, Q3 2014 & Q4 2014... the user can select the quater from a multivalued text box...

Now for the final output, have created another query which pull the above four quarter in each column from the cross tab...now the problem arises when i change the quarter to Q2 2014, Q3 2014, Q4 2014 & Q1 2014..it gives an error "Microsoft office Access database does not recognizes "Query name" as a valid field name or expression".

The error is because the second layer of query does not identifies Q1 2014.

How do i make access change the column automatically when the Q1 changes to Q2...

Modules & VBA :: Input String In Column Based On Data In Another Column?

Nov 30, 2014

I need to input a string into a column named "EventType". The code should first check if the column "Agent Name" contains any strings. If there is none, it will input "IBM Director" into the EventType column.

Once it has looped through the agent names, the code will then loop through the Details column and input into EventTypes based on what is displayed within the string.

These are the codes that I am using to achieve this, however nothing is being input into the EventType column.

Code:
Private Sub Command11_Click()
Dim dbs As DAO.Database
Dim rst As DAO.Recordset

Set dbs = CurrentDb
Set rst = dbs.OpenRecordset("Final")

[Code] ....

I think the problem lies with the code that checks the agent name. When I removed it, it managed to populate the EventType column based on the details. But I still need to find out how to check the agent name too.
