Queries :: Finding Previous Record Date Difference?
Dec 17, 2013
I am trying to use a query to find the previous record of a transaction and provide an additional field that computes the difference in the dates in days. (The days from TransferID 23 to TransferID 24)
I have the below query (A). How do I calculate the Day of Therapy as shown in B
A MRN Last Name DOA Service startDate INR Dose WarfID VisitID 12001 Smith 6/28/2013 Warfarin 6/29/2013 1.20 6 mg 10 138 12001 Smith 6/28/2013 Warfarin 6/30/2013 1.20 6 mg 11 138 12001 Smith 6/28/2013 Warfarin 7/1/2013 1.3 6 mg 12 138 12001 Smith 6/28/2013 Warfarin 7/2/2013 1.40 6 mg 13 138 12001 Smith 6/28/2013 Warfarin 7/3/2013 1.40 7.5 mg 14 138 12001 Smith 6/28/2013 Warfarin 7/4/2013 1.70 7.5 mg 15 138 12001 Smith 6/28/2013 Warfarin 7/5/2013 2.00 7.5 mg 16 138 11002 Brown 7/1/2013 Warfarin 7/1/2013 1.00 2 mg 17 139 11002 Brown 7/1/2013 Warfarin 7/2/2013 1.3 4 mg 18 139 11002 Brown 7/1/2013 Warfarin 7/3/2013 1.50 2 mg 19 139 11002 Brown 7/1/2013 Warfarin 7/4/2013 1.8 2 mg 20 139 11002 Brown 7/1/2013 Warfarin 7/5/2013 2.20 2 mg 21 139 1205972 Jones 6/28/2013 Warfarin 7/6/2013 1.0 6.5 mg 29 138

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.
I need to know how to auto enter the date of the previous record into a new record. I have this db for my vehicle log sheets and I submit monthly a claim for the business km from my company. I usually cant remember the date of the previous claim and have to scroll back until I find the field with a date. It will be useful if the date was copied into every new record until I edit the date when I submit the claim. What I ask is during the new month all the dates will be the same until I submit the claim. I do not know how to do this, and yes I have done a search.
Is there a way, in a query or via the use of a module, to calculate the workdays between two dates excluding holidays without needing to maintain a separate table with the holidays listed out?
For example, I would like it to calculate 21 work days for the month of May. However, I don't want to have to go in the first of each year and manually list out all the holidays for the year. Is there a way for the Holidays table to just contain the number of holidays in a given month (i.e. in December we get 3 holidays (Christmas Eve, Christmas Day, and New Years Eve).
I have to create a query in access that will calculate two Date and time fields [Date & Time Left]/ [Date Returned], need to figure out between the two fields. Trying to identify when the rep returned the call and the number of business hours (6:00am - 4:30pm) it takes to return a message in Ms Access 2010.
The only issue is the calculation has to be done by time and so I have to calculate what time they left the message(so the difference between [Date & Time Left] and [Date Returned) [Date & Time Left] and when the rep returned the message which is suppose to be [Date Returned] but the problem with this field is the data entry is in date format (10/9/2014, 00/00/0000) of Date and not Date and Time like the [Date & Time Left] field, so I don't know what to do now. Not sure what to do now not a database that create or have allot of control over.
I have a form with a date field on it. I would like the date field to automatically enter today's date, which it does now, but also I would like it to retrieve the previous record's date and if it is different from today's date, I want the form to use the previous date as the default value.
I'm struggling with a query to evaluate current and prior record data. I have a query producing 5000 records. I need to group records by Case ID and compare current date record to previous date record to determine if a team and worker name has changed during the year. I need to count how many times a cases is transferred to and out of a particular team from the beggining of the year. i.e., On 1/1/2014-Team1 has an inventory of 500 cases.
During the month 25 cases are transferred into Team1 and 15 cases are transferred out of Team1. So on 2/1/2014 Team1 begins with an inventory of 510 cases. Throughout the year cases come and go from and to Team1 each month so need to figure out how to create a query to count each change. See attachment displaying how the data is listed and how I invision it to work with the In/out column counts.
Specifically, at the begginig of the year (1/1/14) for case ID 1003 you can see it belongs to Mary in Team1 for January and February. Then in March the case is transferred out and went to Joe in Team 3. So for Mary a "-1" is recorded as a negative count for that Case ID. If later in the year the case is transferred back to Mary a "+1" would be recorded. Respectively evaluated for each of the 5000 records to get a total count for each of the teams by Case ID throughout the year.
I've started with DLookup, tried comparing current month to previous month using DMax. It works as long as I only select one case ID used in a separate query but if I use the whole subset (5000 records) it fails. I can't figure out how to group each set of case IDs and then apply the query.
There are three tables. An [Action Register] table, a [Calls] table and a [tblContacts] table. The Contacts are common to both.
The Calls table records calls to customer by date
The Action Register table records issues that Customers send in by Open date.
I am trying to make a query where we see the latest date the customer was contacted regardless of which table.
I created two queries.
qryLastCallDate finds the max date from the Call table:
SELECT Max(Calls.CallDate) AS MaxOfCallDate, tblContacts.ContactName FROM Calls LEFT JOIN tblContacts ON Calls.ContactID = tblContacts.ContactID GROUP BY tblContacts.ContactName ORDER BY Max(Calls.CallDate);
qryLastIssueDate finds the max date from the Action Register table:
SELECT Max([Action Register].Open) AS MaxOfOpen, tblContacts.ContactName FROM tblContacts RIGHT JOIN [Action Register] ON tblContacts.ContactID = [Action Register].Contact GROUP BY tblContacts.ContactName ORDER BY Max([Action Register].Open);
The problem I am having is that if I use Left Join I can see all the records from the Calls table but not all from the Action Register table. And vis versa if I use Right Join. This is because sometimes we have calls but no issues in the Action Register table and sometimes issues with no calls.
This is my Left Join query using a Min Max Module I found here: [URL] ....
SELECT qryLastCallDate.ContactName, qryLastCallDate.MaxOfCallDate, qryLastIssueDate.MaxOfOpen, qryLastIssueDate.ContactName, DateValue(MaxOfList([MaxOfCallDate],[MaxOfOpen])) AS [Last Contact], ([Last Contact]+21) AS NextCall FROM qryLastCallDate LEFT JOIN qryLastIssueDate ON qryLastCallDate.ContactName = qryLastIssueDate.ContactName;
How do I get to see ALL the records from both queries.
I have a database that is used (partially) to enter appointments during a day. In the appointment column I've entered the date and time as dd-mmm-yyy-hh-nn-ss. I'm now trying to search for appointments entered on a specific day through a user input ([Enter Date] in the query criteria) Problem is, this only returns records where the time hasn't been entered and the time shows as 00:00:00.
I've tried CDate which gives me add/mmm/yyy return. if I try to search against that I get nil returns though. As a test I put DATE() in the criteria but it then says that it's an invalid foremat. I've also tried various machinations of "Like" and "Between" without success.
So I'm trying to do this database for my ICT coursework and its a full system for dog kennels.
So in actuality the rooms are kennels.
I have a table tblbookings that amongst others has fields:
Kennel No Date In Date Out
I need a way of users entering the requested dates for a new booking and getting an output of a list of all kennels that are available to book for that full date range or even better, a way of running this straight from the form for a new booking frmbookings to just leave the first available kennel no. in the field KennelNo?
How to find the max value of a field in a query... How does a query display the max record based on the primary key... want to isolate the last record created, the one with the max primary key.
I need to add two previous record fields together in a query. I have attached a picture to illustrate.
The "StudyYears" filed is the primary key of the table the data is being pulled from. The zero's are placeholders for the sum of the previous record's data.
How do you compare one record to the previous record? I have a query that shows items sold. It is sorted by day with today on top. I would like to create a column that has a 'thumb up' or 'thumb down" if todays was a better day than yesterday.
I have a table that will have ITEMID as unique field but location could have save values. I tried using DLOOKUP to look at the value for the previous record to see if I need that value is same as current, however, since my data query are text formats, I am unable to. I get a message of mismatch data type. apply my query to look at sorted table by Location and ITEMID and if previous location = location, then my area=0?
I've got stuck in preparation of this sales query. The primary sales table contains a mix of Canadian and the US detail invoice sales records. All sales records are in their native currencies The secondary lookup table contains daily US/CAN foreign exchange rates (FX).
I need to multiply every $US sales record (marked with U) with the FX rate in order to convert it to the Canadian currency. Unfortunately, this FX lookup table is missing over 50 daily rates in the last two years and as a result I cannot match them date-by-date with the sales table.
As a workaround, it is acceptable to use the previous FX rate in the table. The previous rate can be one or more days before the transaction occurred.
Attached is a sample database with the query that I've already built. The query contains two sample US records that are missing the FX rate on Jan 6. The FX rate of $1.0639 that needs to be applied to it should come from Jan 3rd entry.

I have a database where I need to record student data, specifically marks and absenteeism. The marks are recorded each term as a running total. I have a final mark which needs to be equal to the 4th term mark.
I also need to record the number of days absent each term with a total at the end of the year.
My problem is that the term 4 mark is a in the previous record and the total days absent needs to be the total of the previous 4 records (term 1 - 4).
I using a create table query and an update query but that was a no go.
I want to get the datediff of the last returned date from vacation and the current vacation start date. But how to get difference from the previous record's date to this current record's date. I want to show date difference in an unbound textbox. I have a contiuous form which shows all vacation list of employees. It shows how many times he went vacations and when he went and when he returned.
I have a form that is used to book a new event for a client who is already in the database.Within that form I have a subform that is based on a query which displays information from that client's previous event. I did this using a solution found in the following thread: URL...It is based on pulling the second to last record that is related to the current client. It works perfectly when booking a new event that has taken place on a previous date. However, if the previous event occured on that same date (but at a previous time), it doesn't register.
I would prefer a query that would pull the record previous to the current one, instead of pulling the second to last record out of all that client's events.it would also mean that if more events are booked, then a past event is opened in a form, the sub forms in that form will display the event just prior to the current record.
I'm trying to refer to previous record in a query and i'm stuck as i do not know how to do it.
Here is my query:
Code: SELECT [Prod2Buy].[Product Code], IIF([Missing] IS NULL,0,[Prod2Buy].[Quantity To Order]-[To Order]) AS [Rest To Order], s.s_manu_code AS [Manufacturer Code], s.prod_cost AS [Price Code],
[Code] ....
In fact the line: IIF([Missing] IS NULL,0,[Prod2Buy].[Quantity To Order]-[To Order]) AS [Rest To Order] should refer to previous record.
I'm having trouble with a Form and getting a text box entry box (Date entry) default to the date entered on the last record, which is linked to a table.
The only way I can get it to work is to type the date into the Text Box's Default property, for example, #11/13/13".
How to get the correct syntax or code into the Default property of the Text Box to make this work? I only want the entry to change versus the previous record/entry if the User changes / enters a new date.
I'm setting up some analytical reports and i'm having a hard time with some date criteria.
I've gotten monthly averages already and what i want to do is take those monthly averages, and average them throughout the year. (the year being from the specified date on a form control back one year)
Month([Forms]![Report Runner]![Date1]) and Year([Forms]![Report Runner]![Date1]) worked great for specifying a certain month in a certain year, but what i'd like is to show all the monthly numbers for every month going back one from [Forms]![ReportRunner]![Date1].
I tried this:
Code: >(Year([Forms]![Report Runner]![Date1])) And <((Year([Forms]![Report Runner]![Date1]))-1)
I want substract from 9/20/2014 totreg40 - reg = ovt but when reg=0 the remainder subtract from 9/19/2014 (previous record) totreg40 - reg = ovt, etc. The sum of reg = 40.
I have a column "CAT" each time that CAT switches between 0 and 1, I would like my query to auto-create a "grouping" and increment the group by 1. What I am looking for is the output as shown below.
