Queries :: Find A Way For Access To Find Unique Dates And Unique Names?
Aug 1, 2014
I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:
Start Date/Time
End Date/Time
Employee
At the moment this is what the format of my report looks like (I removed other unnecessary fields):
StartTime----------EndTime---------------Employee
12/06/2014 01:00--12/06/2014 03:00------John Smith
12/06/2014 04:00--12/06/2014 06:00------Jane Doe
13/06/2014 02:00--13/06/2014 05:00------John Smith
13/06/2014 08:00--13/06/2014 08:00------Jane Doe
I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?
I thought this would be relatively simple task to complete but its proving tricky.
I have two tables with the same data: E1 and E2
E1 has two columns and is as follows
A 1 B 2 C 3 D 4
E2 is similar except for one record '5'
A 1 B 2 C 5 D 4
Now the task is to show those records that do not match...in this instance
E1.Field1 E1.Field2 E2.Field2 C 3 5
Now I've used the find unmatched wizard and this is the SQL: SELECT E1.Field1, E1.Field2, E2.Field2 FROM E1 LEFT JOIN E2 ON E1.Field2 = E2.Field2 WHERE (((E2.Field2) Is Null));
this is giving me partially the right answer as in E1.Field1 E1.Field2 E2.Field2 C 3
Each Product can be in the table mulitiple times depending on how many Build ID's it has. So if Product 123456 has Build ID's G004, E818, N005, F813, D024, C879 it will show up one time each for each Build ID. What I want to query is unique Products that are for Build ID's D024 & C879 only and not for G004, E818, N005, & F813.
How can I accomplish this with a query. I am sure I am making this harder than it is but I sure need help.
I want to do a unique count of dates when an activity was done in my table. The table may have multiple entries of the activity performed possibly on the same date by an individual
totV = ECount("[dateAssessed]", "R_P_Data_P", "[approvalNoSys] = '" & [Forms]![cmrOverview]![txtappNoSys] & "' AND [Activity] Like '*audit*'") totV = Unique count dateAssessed = date field in R_P_Data_P table R_P_Data_P = table "[approvalNoSys] = '" & [Forms]![cmrOverview]![txtappNoSys] & "' = criteria for the customer in question to separate them from many other customers in the table. Activity = text field in R_P_Data_P table audit = the activity
I'm also trying to avoid having to build total queries etc to them reference them, I'd like getting the desired outcome in an expression or small code.
I read about Ecount but my complier doesn't recognise the function
I have 2 linked tables, tblPN & tblReceivedDate. tblPN has field PN and tblReceivedDate has field [Received Date]. The tables are used to record the receipt of different part numbers and the date they received. I want to use a query to count how many times a part number is received. The catch is that I only want to count a part once even if it is received more than once on the same date. With the data in the attached DB the count for PN 123 would be 5.how to configure the query to do what I need to do?
I need a query to find all the field header names that contain string "PL-" and along with records contain a value with the field name containing "PL-" within a Access DB table.
I've recently finished constructing a database that uses forms with checkboxes i.e. when a user opens a form there are several checkboxes associated with labels, but the table only stores the check-boxes and the form labels are the field (column) names on the table.
Now, what I'm trying to do is create a search feature whereby if a keyword search is conducted, a search through the column names from the table with checkboxes takes place and only lines (rows) with true (checked) checkboxes are returned.
I've got two tables, both are indexed by customer ID, with a series of dates against the customer ID. One has a list of all dates a customer was visited, the other is a list of dates where activity happened on the customer account
I want to get a list of the dates when the customer was visited but where no activity happened on the customer account, i.e. where there is a customer visit date on the customer visit table but no record for that date on the activity table.
How do I do that? I can find all dates where was a date was on both tables, but how to find where its on one but not the other
I have create 6 tables for library books (which are differentiated by categories). Each table has different category and unique ID name e.g. F1, F2, F3..(for table 1), G1, G2, G3..(for table 2) and so on. How do I combine all those tables into 1 table for easy search for a book rather than open up each table? Tried append query but its ID run as 1, 2, 3... , not F1, F2, F3 and it only append 1 table, not the rest.
Code: tblPrice PosNr PriceDate Company Price 1 01.01.2014 Firma A 5 2 02.01.2014 Firma A 7 3 03.01.2014 Firma A 9 4 04.01.2014 Firma A 8 5 06.01.2014 Firma A 6 6 02.01.2014 Firma XY 11 7 03.01.2014 Firma XY 9 8 04.01.2014 Firma XY 7 9 05.01.2014 Firma XY 8 10 06.01.2014 Firma XY 10
And I have a table with the dates, for which I need a price.
Code: tblDates PosNr PriceDate Company 1 01.01.2014 Firma A 2 02.01.2014 Firma A 3 03.01.2014 Firma A 4 04.01.2014 Firma A 5 05.01.2014 Firma A (no price available) 6 06.01.2014 Firma A 7 02.01.2014 Firma XY 8 03.01.2014 Firma XY 9 04.01.2014 Firma XY 10 05.01.2014 Firma XY 11 06.01.2014 Firma XY
And now I want to combine this tables, and for the dates which have no price, the last price should be taken.
Code: tblResult PosNr PriceDate Company Price 1 01.01.2014 Firma A 5 2 02.01.2014 Firma A 7 3 03.01.2014 Firma A 9 4 04.01.2014 Firma A 8 5 05.01.2014 Firma A 8 (actualy no priceavailable, so take last price) 6 06.01.2014 Firma A 6 7 02.01.2014 Firma XY 11 8 03.01.2014 Firma XY 9 9 04.01.2014 Firma XY 7 10 05.01.2014 Firma XY 8 11 06.01.2014 Firma XY 10
how I can get this?
I have this code, but it need hours.
Code: SELECT tblDates.PosNr, tblDates.Company, tblDates.PriceDate, (SELECT TOP 1 B.Price FROM tblPrices As B WHERE B.Company = tblDates.Company AND B.PriceDate <= tblDates.PriceDate ORDER BY B.PriceDates DESC ) AS Price FROM tblPrices RIGHT JOIN tblDates ON (tblPrices.PriceDate = tblDates.PriceDates) AND (tblPrices.Company = tblDates.Company);
I Have one table which have 4 column ,i.eID , NAME, PAN, DOB..in this table same id having diffrent data of Name or PAN or DOB except DOB all are text format when i m trying to select unique id which having more than 1 name it shows 0 data, but table having these,,
SELECT tblCurrencies.CcyID, tblCurrencies.Ccy FROM tblCurrencies ORDER BY tblCurrencies.Ccy;
Now - I have a separate table of balances, which is linked to the currency table by the same CcyID, and which also has identifiers to link it to other tables (e.g. AccountID)
As part of the above query, I want to return the count of unique AccountID's in the balance table for each currency. So in other words, I want to know, for each currency, how many unique accounts exist?
Each AccountID could appear one or more times in the balance table (one-to-many relationship), so I only want to count the number of unique ID's.
So I started with the following :
Quote:
SELECT tblCurrencies.CcyID, tblCurrencies.Ccy, Count(tblBalances.AccountID) AS NoOfAccounts FROM tblCurrencies INNER JOIN tblBalances ON tblCurrencies.CcyID = tblBalances.CcyID GROUP BY tblCurrencies.CcyID, tblCurrencies.Ccy ORDER BY tblCurrencies.Ccy;
But this just gives the number of AccountID's per currency (regardless of duplication within them)
I found this article which informs me that a Count(Distinct) query won't work in Access and to use subqueries instead.
I am trying to find the latest date in a table where the dates are in 2 separate columns and multiple rows. (there are business reasons why there are 2 dates per row they represent different but comparable activities)
I have a table "Assessment tracker" with the following structure
Name Type Candidate short text Unit short text EV1 Date Date EV2 Date Date
My Data:
Candidate Unit EV1Date EV2 Date TH1 10 07/05/2015 25/05/15 TH1 10 07/05/2015 07/06/15
I have a query "Candidate AC Dates" that compares the 2 dates EV1 and EV2 and outputs a 3rd column with the latest date.
It does this by using a function shamelessly copied from the web somewhere...
Function Maxdate(ParamArray FieldArray() As Variant) ' Declare the two local variables. Dim I As Integer Dim currentVal As Date' Set the variable currentVal equal to the array of values. currentVal = FieldArray(0) ' Cycle through each value from the row to find the largest.
[Code]....
This is working well (I think)
I then want to find the latest date for the 2 records i.e. the Max value for the Achdate.
Query: SELECT [Candidate AC Dates].Candidate AS Expr1, [Candidate AC Dates].Unit AS Expr2, Max([Candidate AC Dates].Achdate) AS MaxOfAchdate FROM [Candidate AC Dates] GROUP BY [Candidate AC Dates].Candidate, [Candidate AC Dates].Unit ORDER BY [Candidate AC Dates].Candidate, [Candidate AC Dates].Unit, Max([Candidate AC Dates].Achdate) DESC;
But this is returning
Candidate Unit MaxOfAchdate TH1 1025/05/2015
I expect it to return
Candidate UnitMaxOfAchdate TH1 10 07/06/2015
It looks to me like MAX is considering only the day value rather than the whole date. I suspect this is because it is considering the results of the function in the first query as a short text rather than a date field. (I've tried to force this through declaring the variables as dates but don't know where else to force this. (I am UK based hence the DD/MM/YYYY format)
I have an Access front end linking to an SQL Server back end. My question is: Using VBA, how can I find the Group Names for groups I've got set up in SQL Server?
The database I'm working on is used for personnel budget projections. Because some employees are hired mid-year, I need to be able to use various dates in my projection calculations.
I have 3 different tables - one with the employee start date, the other with the fiscal year start date, and the last with the start date of certain special pay tables. In order for my projections to work correctly, I'll need to return in a query the minimum of these 3 dates. I know how to do a minimum value in a single field within a table, but don't know how to select a minimum from multiple values in multiple tables. Is this possible.:rolleyes:
I have over 180,000 records that I need help on. Here are key fields I have:
Students Address1 City State Zip Year applied
My problem here is that, for example, say these students apply for Financial Aid. Each year a student can apply for aid. However, the data collection never got the people’s SSN, so there is not a unique ID. It only created a unique ID by autonumber only. What makes this complicated is that students sometimes change their names. For example, let’s use Joe Schmoe applied for the following year with these names:
2001: Joe Schmoe 2002: Joey Schmoe 2003: Joseph Schmoe
Now, I could tag it by zip to filter it down, but anyone looking at these record can tell these 3 records are the same person, but Access reads it as 3 different recordsets. I do not want to manually manipulate the data (i.e. make the name congruent OR create a unique ID for these 3 records and joining tables). To manually manipulate all 180,000 records is crazy.
The record of over180,000 came from various sources through excel. The DB was created using only 1 table.
Is there a way to manually manipulate the data in an easy way? Thanks for all your help, guys.
I have a material usage table that tracks material going into products...Oftentimes the same material will be used and multiple records will contain that material.
I want my query to return only records with unique material used. I'm clicking the "Unique Values" and "Unique Records" property setting but its not working.
I'd like to extract just one TestPos record (TestPos = 1) per Patient ID. And I always want to select the record with the earliest date. So the result would be:
I can do this but it requires 3 queries: a SELECT query where TestPos = 1, a GROUP BY PatientID query and MIN(VisitDate) to get the desired record per patient, and then another query that links the two so I can get the additional variables (e.g., Complaint).
Is there a way to do this without using 3 queries? Seems inefficient.
The main table for the database I am working on contains the following fields:
ID Mfr Control Number Initial or Follow-Up Follow-up Number Suspect Date of Initial Email Date Received Date Submitted Date of Report Serious Brief Description Causality Notes
With some additional qualifications I wanted to find records that had an intial report but no follow-up. Which translates too I want records that are unique in the Mfr Control Number field (no duplicates).
I am trying to build a query and keep getting hung up on the unique aspect of fields. I started by trying to query only "Mfr Control Number" fields that are unique (no duplicates). As best I can figure for some reason I can not add any additional fields to that query. My current query is set up in the query build table such that I have added "Mfr Control Number" in two columns. The first column in Total I have "Group By". In the next column I have set Total to "count" with a criteria of 1. If I try to add any other fields from my table than I seem to lose those unique results. But I need to further filter to get the exact information I need.
I want criteria on the "Initial or Follow-up" field to only bring "initial" I want criteria on the "Serious" field to only bring "serious" I want criteria on the "Date of This Report" field of "<Date()-"15""
Is there some way to take the results of that initial query to then build a another query based just on those records? I could then apply the further criteria and run my report. Or is there a way to do this in one step?
I've tried to make clear my intention but know it can be difficult to get this kind of stuff down in writing in a clear fashion. I have to be careful to keep information confidential also so some of the details are vague.
I have imported a large number of emails into a table tbl_requests.
I had intended to have unique file tbl_requests.date_opened unique, but have ended up with a lot of duplicate records (i.e. tbl_requests.date_opened is not unique !). How to delete any duplicates? I have 15,000 records...
I have a query with over 85,000 lines of data where each row has a unique id but the unique id appears multiple times within the table. For example, there is a unique numeric id tide to various types of pets across four columns. So the id number 1 could appear in four different rows each with different pets. See the first attachment "Original Table"
I want to be able to create a table that has one for for each unique id with all of the corresponding pet data. See the attached "Desired Table".
