Compare Two Types Of Records From One Table
Aug 9, 2011
I am trying to create a query based on a transaction table which compares the time between two types of transactions.
The initial record would have "A' in the type field and the second record would have "D" in the type field.
each pair of A and D records would be matched on o_time and idnum fields, and I would want to pull each pair and us the datediff function on c_time, using records marked with A as the initial time and records marked with D as the followup time.
Is there any way to accomplish this in a single query or do I need to create two subqueries?

Hi
I'm using MS Office 2000, I have an Access database table that contain many fields, namely I need to update FieldA from an Excel Spreadsheet according to the specified primary key of CustomerID. Is there a way to write automate process to import the records from an excel spreadsheet and then place those records in FieldA of the Access Database according to the corresponding CustomerID? The reason I ask is that these two fields are not exactly in the right order in my spreadsheet and my table and to do it manually will take lots of effort.
Your prompt response is greatly appreciated
Thanks

Hi,
I am designing a database.
It is going to store data from questionnaires.
The natural way seems to be to have a table - that stores where the data comes from, what is it about, what is the question and what is the answer, like this:
DataProviderID; FocusID; QuestionID; AnswerValue
My problem is that a Focus could be a eg. a Person, a Company or a Job - meaning that somebody may be giving info on an other person, on a Company or on a Job.
Now Persons, Companies and Jobs would have very different properties.
So how should I solve this shold I have a common table for Peoples, Companies and Jobs and use a very complicated structure of properties for them or should I store these entities in separate tables but than how will I store the results?
Thanks for your thoughts.

Not even sure where to start so if this isn't a query question, please point me in the right direction.
I work in a plant that has a number of cranes. Each crane should be inspected each shift (three shifts per day), each day (less Sunday).
I have exactly what I need to capture the inspections being done. Inspections are identified by crane #, shift, and date.
How do I determine if an inspection hasn't been done? How do I compare the inspections that have been entered against the standard of inspections for each crane, each shift, each day?
I am below average with Access on my best day so please type slowly and be specific. Thanks for any help you can give.

I have a table that contains the following fields: ID (autonumber), Item, billing date(mmm/yyyy), count, and approved.
My first query returns records where the approved field is null. My second query returns returns all records for 2 months ago where the approved field is not null.
This is my problem, I need to pull records that have NOT been approved for the prior month BUT if they were approved 2 months ago AND the count is the same, it does not need to be returned in the query. Also, if it was approved 2 months ago but the count is different than what it is for 1 month ago, it needs to show in the query.

So I have a table:
table1: company_name, year_month, company_rating, rating_change
For each company, I would like to compare the rating from 201201 and 201202 (and keep going for each month) and if there's a change in the rating, update rating_change to the difference in rating values.
The company_rating is a value from 1 to 20.
How should I go about doing that?

I have a table called tblAuthorizations. It appears as follows
AuthInstanceID....ConsumerID....AuthNumberID....Au thStart....AuthEnd....PSRUnits....BSTUnits
1374006036.........356679..........20255102....... ...4/22/13......7/21/13.....0..............416
-432536491.........356679...........20255102....... ...1/21/13.......4/21/13....104..........416
-124970517.........356679...........20147863....... ...10/23/12.....1/20/13....208..........520
504564357...........469432..........20254788...... ....4/22/13......7/21/13....0..............520
282523535...........469432..........20254788...... ....1/21/13.......4/21/13....0.............520
I work in mental health, and when we put in a request for a consumer to receive PSR & BST services, we put the above information into our database. Each record identifies which consumer the authorization is for, a start date and end date for them to receive services, and the amount of two types of services (PSR and BST). When one period ends, we request another period, such as in the first three records above, and then the final 2 for another consumer.
What I need to be able to tell is how their service authorizations change. For instance, if I were to compare the first and second records, it would tell me that PSRunits decreased 4/22/13-7/21/13 from 1/21/13-4/21/13 levels.
I have a query that displays the records for each consumer for the current period, but I can't figure out how to identify the previous period's number of PSRUnits or BSTUnits.I've tried adding the following fields, but this isn't working.
PrevEnd: (Select Max(AuthEnd) from tblAuthorizations Where AuthEnd < Auths.[AuthStart])
PrevBST: DLookUp("[BSTUnits]","tblAuthorizations","AuthEnd=" & [PrevEnd] And "ConsumerID=" & [ConsumerID])

I have created a mock employee database to work out kinks before I create the real one. One table has employee info (employeeID, name, address, email, phone numbers, etc.). The other table has "employee actions" with fields: employeeID, actiontype, salary, jobtype, jobtitle, jobhours, bonus, actiondate. Actiontypes are "hire", "salary change", "bonus", "leave". It is a little more complicated but that is irrelevant to my query question...
I created a query to show employee salary changes, amount and action date. I want to create a calculated field that shows the dollar change and percentage change from last salary to new salary. So the query involves multiple records or rows, which seems to be a black hole in terms of information on how to do this. If it were Excel, I would just do a quick nested function calculation and be done with it but with Access, where each record is independent of the others, how to calculate it. I know there must be a way to do this because otherwise, what good would an employee database be?
So the questions are: (1) can you do calculations (other than totals or counts) using multiple records/rows? and (2) if so, how do I do it? It seems I would have to do a a specific sort and it would not be easily updatable.

Hi Everyone,
I have a PO table. Each PO has 3 documents of multiple types (one may be Word, other may be Excel, Acrobat). When I display the PO, the attachments should be shown as Icons, which when double-clicked, will open in its own Application.
I have a pop-up screen where I enter new PO details. In this screen, I have Attach/Detach buttons for each of the Documents.
My Requirement:
When I press 'ATTACH' of Doc1, the File Selection screen should be displayed from where the user will select the file to be attached. This file should be updated into the table field "doc1".
When I press 'DETACH' of Doc1, the file in table field "doc1" must be cleared.
How can I achieve this???:mad:

I have a query which is my list of orders. Now I want to create other type of orders. New types don't use the code in red (tbl Offset and tblRodzajZlecenia). Is it possible to modify the query, in order to keep new types too?
New types of orders are in the same tables. But if I don't fill fields in tblOffset then query can't show new type of oder - that's the problem.
Code:
SELECT z.ID_Zlecenia AS ID, tblRodzajPracy.RodzajPracy AS [Rodzaj pracy], tblRodzajZlecenia.RodzajZlecenia AS [Rodzaj zlecenia], z.NazwaZlecenia AS [Nazwa Zlecenia], k.NazwaSkrocona AS Klient, z.DataPrzyjecia AS [Data Przyjęcia], z.TerminOdbioru AS Termin, tblStatus.Status, tblStatus.lp
FROM (tblKlienci AS k INNER JOIN ((tblStatus INNER JOIN tblZlecenia AS z ON tblStatus.Id_Status = z.Status)
[Code] .....

This the first time I post in this forum and I tried looking for an answer to my question before posting, so I apologize if my question has been answered previously.
Is it possible to determine, in Access 2000, the data type in a Make-Table query of a new column with null value so that it does not default to binary.
Here is my sample sql:
SELECT tblAddressBook.Name, Null AS Email INTO tblTestTable
FROM tblAddressBook;
The output is tblTestTable with two columns: Name and Email. The data type of column Email defaults to Binary. How do I make it default to Text.
Thank you.

I am building a tracking database where we would be able to track information which field are null data and report them to our Administration to fill the null data. For this I have created a form name "Search" and I have a combo box control on that form which is bound to "Table = employee" and its ROW SOURCE TYPE="Field List", I would like to able to query records where the selected value in this combo box is null through out the table.
For example if I select "Telephone" from this combo box dropdown, I would like the query to show all the records where the "Telephone" is null, how to set the criteria in query to take the combo box value as "Field Name" and then compare it with the Field/Column in the table and show the null values.

Hello,
I am just wondering whether there is any query I could use to compare the data on, say, whether all data in Table A are in Table B although some records in Table B may not be in Table A and give me the record that is in Table A but not in Table B.
Thanks!

Hi,
I have a table with four columns - A, B, C, D
I want to compare the values in columns A, B and C in row 1, with the values in row 2 and if they are the same, I want to copy the value that is in column D in row 1 into column D in row 2. I then want to move to the next row in the table and compare the values in row 2 with the values in row 3 in the same way. This will continue for all rows in the table.
Any help would be greatly appreciated as my VB is not up to much.
Thanks in advance

Hi there
This is probably quite easy but I cannot make it work so would appreciate some help. I have a table containing vehicle information. I have 2 fields, Current Mileage and Max Mileage. I want to do a comparison of the 2 fields and should the Current Mileage be greater than the Max Mileage, the query returns the Vehicle Registration. Test data has been entered in the table I am querying and I was expecting 1 value to be returned. However the query as I wrote returned either all the vehicle Registrations or none of them. Can someone help with this please.
Thanks in advance for the assistance
Craig:)

I'm willing to be this is simple, but I haven't been able to figure it out.
I have created a database with one table, tblUserData. I have one form called frmLogin.
tblUserData has two fields, Username, and Password.
frmLogin has two textboxes for user input, User and Pass, and has one control, cmdLogin.
What I am trying to do is - When a user types their username and password, and clicks on the control
button, the value of User.Value is compared to the Username field of the UserData table.
If a matching record is found, then Pass.value is compared to the Password field from the matching record.
If they match then the program proceeds.
Can anyone point me in the right direction please?

Hi,
I am trying to compare two columns' values within the same QUERY table, but I kept on getting the "Data type mismatch in criteria expression" error. What am I doing wrong?
Here is my Select Query Statement:
SELECT qryDedparmDedetail.EMP_ID, qryDedparmDedetail.[Employer Amt], qryDedparmDedetail.[Employer Actl], qryDedparmDedetail.[Admin Amt], qryDedparmDedetail.[Admin Actl], qryDedparmDedetail.[Employee Actl], qryDedparmDedetail.[Employee Amt], qryDedparmDedetail.FirstOfSTATUS, qryDedparmDedetail.FirstOfAGENCY, qryDedparmDedetail.FirstOfTITLE, qryDedparmDedetail.FirstOfFORMAT_NM, qryDedparmDedetail.RepUnit, qryDedparmDedetail.FirstOfDEDTYPE_CD1 AS Expr1, qryDedparmDedetail.SumOfNBR, RepUnit.REPUNITDESC, qryDedparmDedetail.LeftType

I have a form that users put in information and then it updates to a table. It works fine but i would like to add something. Right now there is a text box called item that the user puts in the item number. The problem is that sometimes they put in a wrong number. What i would like to do is have it when they hit the update button to compare that item number to a table that lists all of them. so if the text box doesnt equal one of the numbers in the table dbo_item and the field itm_num, i want it to give them a message box with an error.

I am running into an issue when trying to compare data stored within the same table.
tblParcels - holds data relating to an individual parcel of land; unique identifier is ParcelID. No repeating data.
tblValues - holds data relating to the value(s) of each parcel; new values entered annually; unique identifier is TaxID; has field to link to tblParcels. One parcel can have multiple entries for each year tracked.
I have two unbound text boxes on frmMainForm where users can enter Tax Years to compare (txtYear1 and txtYear2). Theory being that users will be able to select any two tax years and compare the parcel values.The report (rptMaster) is built using three queries and is used to show the change in value between txtYear1 and txtYear2:
qryYear1 - pulls all values from tblValues where the TaxYear equals the year typed in txtYear1.
qryYear2 - pulls all values from tblValues where the TaxYear equals the year typed in txtYear2.
qryCompare - joins the results from qryYear1 and qryYear2, along with other common fields, and populates rptMaster.
My problem lies when a parcel does not have any values for one or both of the years entered into the text boxes. I completely understand why, qryCompare can't show any records if there are no results coming from either qryYear1 or qryYear2. What I am not getting is how to work around this issue.I would like for the report to show "$0.00" for the value if there is not a value for that Parcel in tblValues for the year entered.
tblValues example data:
TaxID ParcelID TaxYear Value
1 5 2011 100,000
2 5 2012 200,000
3 6 2012 75,000
In the example above, when comparing 2012 values to 2011 values, my report shows the values for ParcelID 5 but not for ParcelID 6 as it does not have a 2011 value (and won't since information about that parcel didn't exist in 2011).

I am programming an Acess Database, the primary data come from an excel sheet. Since Access one to many relationship only works for primary key and another field in another table as foreign key, I can't have normalized database.
I will explain what I mean with a hypothetical situation.
So, let's say I have two tables: WindowT1, CustomerT2.
WindowT1 has fields: WinID (the pk), WindowName.
CustomerT2 fields include CustID (pk), CustomerName, WindowName, WinID.
So, in table "CustomerT2', WinID is the foreign key and I need that field filled in to make one-to-many relationship between these two tables to work. CustomerName and WindowName will be imported and prefilled already from an excel file with append query.
My question is can I make a update query (after the initial append query that brings in the data into Access) such that the criteria is matching WindowName (from CustomerT2) and the update would be the corresponding WinID (the pk number from WindowT1) that would be filled in the field WinID (in CustomerT2)? I know for this to work tables must have relationship and I did that.
Is there a better way to accomplish this task? i.e. through a form (remember info will be prefilled, so can't use combo box to fill in another form field) or maybe can I do this using the first append query (that brings in data)?
I am not good at Macro or VBA. The only thing I have done in code builder is After Update event in forms while using combo boxes. So, if there is no easier solution, I will try to deal with codes.
