I have just joined the forum and spent the last day or so looking around for an answer that I wasn't able to find.
I have been asked by my employer to capture details of who has signed our confidentiality policy. I have made a very simple database which only has three tables, EMPLOYEE, POLICY and VERSION.
EMPLOYEE has three fields, NAME, NUMBER and BRANCH. POLICY has three fields, NUMBER, DATE and VERSION. VERSION has two fields, VERSION NUMBER and DATE. I won't worry about the VERSION table any further in this post as it doesn't figure in the problem query.
Primary key for EMPLOYEE is NUMBER. Compound key for POLICY is NUMBER and DATE (ie. the employee can sign the policy more than once and we want to record when this was, and whether the policy version changed).
I have an Access "type 3" join defined in table relationships from EMPLOYEE.NUMBER to POLICY.NUMBER.
I am trying to write a query that returns the employees that haven't signed the policy. I have no problem returning the employees that have (ie. employees whose numbers match the numbers in the POLICY.NUMBER field), but it is the EMPLOYEE.NUMBER entries that are not present in POLICY.NUMBER that are causing me grief.
I have tried using the expression builder in the query builder window (it gave me <>[tblPolicy]![Number]) which doesn't return any records (I have over 490 in the database and should be getting back at least 50 or so).
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Depending on the answer of a question, i would like to get the records that have no data in that specific field, otherwise i want the query to give me all records. I've tried this in "criteria" but it doesn't work: IIf([Question? J/N]="N";"Is Null";"")
Hi. I'm unable to work out how to set up a query which will filter records according to what is returned by one control, but will also list all records if the value of the control is null.
Situation: I have a CONSULTATION table linked many to many via a CONSULTATIONLIST relation table to an ADVISOR table. (An Advisor may be present in any number of Consultations, and a Consultation may include any number of Advisors.)
I have a CONSULTATIONMANAGE form enabling the user to select an Advisor from the table ADVISOR via a combo box called SELECTADVISOR which returns Advisor ID (adID).
My CONSULTATION form, displaying the list of consultation records, currently has, as record source, the following query:
SELECT Consultation.*, Advisor.adID FROM Consultation INNER JOIN (Advisor INNER JOIN ConAdList ON Advisor.adID = ConAdList.adID) ON Consultation.conID = ConAdList.conID WHERE (((Advisor.adID)=[Forms]![ConsultationManage]![selectadvisor]));
This query correctly lists only those Consultations in which the selected Advisor was present.
Problem: What I also need to do is show ALL Consultation records if the user does not select an Advisor from the combo box.
I have what I think is a simple query returning the names of students that have been dismissed since September 2012 using a "WithdrawnDate" field. The query pulls a lot of information from other related tables (about 6 different ones), and has two expressions.
When the criteria is set to either "Is Not Null" or a date range (which is all I need), it does not return the complete set of records based on the data that fits the criteria in the main table?
Could there be some sort of join preventing all records from being returned?
I have a left-join query where I know that some of the values in the left-hand table have no corresponding values in the right-hand table...that's why I used a left-join: I want all the values in the left-hand table to show up. I would expect that records without corresponding values in the right-hand table would show up as nulls (I swear I have dozens of other queries that work this way) but in this one, they show up as "#error" instead.
This is a problem because I want to do some calculations on this field. Normally I would use the nz function to change the nulls to zeros.
So, 1. Any idea why this is happening? 2. Is there a way to change the #error values to zeroes, similar to using the nz function?
HEre's the SQL: SELECT FeederInventorySummary.machine, FeederInventorySummary.Size, FeederInventorySummary.Leaf, FeederInventorySummary.Type, FeederInventorySummary.CountOfFeederID,FeederNeeds Summary_7.FeederQty FROM FeederInventorySummary LEFT JOIN FeederNeedsSummary_7 ON (FeederInventorySummary.Type = FeederNeedsSummary_7.Type) AND (FeederInventorySummary.Leaf = FeederNeedsSummary_7.Leaf) AND (FeederInventorySummary.Size = FeederNeedsSummary_7.FeederSize) AND (FeederInventorySummary.machine = FeederNeedsSummary_7.ActualMachine);
For every record without a corresponding record in FeederInventorySummary_7, the FeederQty field shows up
Hi, first of all I have to say I'm quite a noob at Access, so I apologise if my question seems stupid. :p I Googled for quite a bit looking for a solution but couldn't really get anything to work (maybe because I wasn't doing some of the possible solutions correctly?).
Anyway, I have a database with two tables, and I'm trying to make a QBF to search for data from these two tables. Quite a few of these entries have null values.
SELECT [M-Table].Firstc, [M-Table].Secondc, [S-Table].Thirdc FROM [M-Table] LEFT JOIN [S-Table] ON [M-Table].Firstc = [S-Table].Firstc
WHERE
((([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*") AND (([Forms]![interface]![TxtFirstc]) Is Null) AND (([Forms]![interface]![TxtThirdc]) Is Null))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*") AND (([Forms]![interface]![TxtThirdc]) Is Null) AND (([Forms]![interface]![TxtSecondc]) Is Null))
OR ((([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*") AND (([Forms]![interface]![TxtFirstc]) Is Null) AND (([Forms]![interface]![TxtSecondc]) Is Null))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*") AND (([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*") AND (([Forms]![interface]![TxtThirdc]) Is Null))
OR ((([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*") AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*") AND (([Forms]![interface]![TxtFirstc]) Is Null))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*") AND (([M-Table].Secondc) Like "*" & [Forms]![interface]![TxtSecondc] & "*") AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*"))
OR ((([M-Table].Firstc) Like "*" & [Forms]![interface]![TxtFirstc] & "*") AND (([S-Table].Thirdc) Like "*" & [Forms]![interface]![TxtThirdc] & "*") AND (([Forms]![interface]![TxtSecondc]) Is Null));
This really long and tedious code was the only way I could get it to work such that in my query form, if I leave any one of the fields blank the search will still pull all the related results out, regardless of whether there are nulls in the values themselves, e.g. if I search for anything with "ab" in Secondc, it will give me all the data with "ab" in Secondc, even if there are null values for those entries in Firstc and Thirdc. Similarly for searches with the other fields.
I tried using IIF and Nz, first using IIF under Criteria, then I read somewhere that they should be used under Field rather than Criteria, but I couldn't really get it to work. Either the QBF wouldn't return any results, or it would return only those entries without null values, so if I searched for "ab" in Secondc, I wouldn't get the entries that had "ab" in Secondc but null values in either Firstc or Thirdc.
The problem with my solution is that I wouldn't be able to get it to work in another database with like 10 fields. The number of combinations would be a killer...
They are all numerical values that I need to format into percentages however Field3 could contain zero so I can't replace Null with zero. I simply want to return nothing if Field1 is equal to Field2.
2007 version - my child query is not returning null values. I have 2 fields, both pulled from a parent query. One is "DaysSinceRecd", the other is "AmountPaying". The parent query returns multiple results, which is fine. For example, the parent query might have 10 different records for "0" "DaysSinceRecd", with different "AmountPaying" for each of those records.
In the child query, I am trying to condense that down, so that I only have one "AmountPaying" for each "DaysSinceRecd". It's working fabulously, except that there are records in the parent query that have a value for "AmountPaying" but a null value for "DaysSinceRecd". The null value for "DaysSinceRecd" cannot be changed to another value, it needs to stay null. My child query is not returning the null records. I tried adding to the criteria: IsNull Or IsNotNull, >=0 or <=0. That's not working.
1. User need to look up item name, while in a subform. He pressed F5 2. A form showed up, with a ComboBox (which got its values from a query) 3. User chose an item name in the ComboBox, and then pressed the Close button 4. The item name got copied into the subform.
Problem is, for some items/records, step 4 doesn't happen :eek: When I investigated, turned out that for some records, the ComboBox returned null (instead of the selected record)
I have 3 tables - Students, which contains all students; Attendance, which contains dates a particular student was absent; and AttendanceCtrl which contains Quarter beginning/ending dates. I need to be able to calculate the number of days a student was present, absent, tardy in a quarter. The query needs to extract all students regardless of whether or not they missed any days. I tried using a Left join Students to Attendance and then joining AttendanceCtrl but Access said it couldn't do it because of "ambiguous outer joins". It said to create the first join then use that query in the second join. I tried that. I created a query with a Left join joining Students to Attendance. That gives me what I wanted, all students from Students and also those students with matching records in Attendance.
The 2nd query is giving me problems. I tried joining the first query (qryStudents) to AttendanceCtrl and calculating my totals. Problem is, the query only gives me students what have records in the Attendance file; it doesn't give me all the students. If a student did not miss any days, I need to show that he was present 90 days out of 90. Because there's no matching record in the Attendance file, I get nothing for those students.
As I said the first query (qryStudents) seems to be working but I need to take the records from that query, group them together by StudentID, and then calculate my totals. How can I do this? Am I approaching this wrong altogether?
I cannot seem to get my query to return all the records i want it to, i want to search by year group, which it is doing fine, but if a record has a table wich does not have data in it, the query will not return that record, i can't find the solution anywhere!
I had a query which was working fine to tell me the number of weekend bookings for holiday parks for a specified year:
SELECT Bookinfx.[Park Name], Month([Start Date]) AS FilterMonth, Year([Start Date]) AS FilterYear, Count(Bookinfx.[Park Name]) AS Bookings FROM Bookinfx GROUP BY Bookinfx.[Park Name], Month([Start Date]), Year([Start Date]) HAVING (((Year([Start Date]))=2005));
However it has become necessary to only find bookings of specific accommodation types so I modified it like so:
SELECT Bookinfx.[Park Name], Month([Start Date]) AS FilterMonth, Year([Start Date]) AS FilterYear, Count(Bookinfx.[Park Name]) AS Bookings FROM Bookinfx WHERE ((Bookinfx.Day)="FRI" Or (Bookinfx.Day)="SAT") And ((Bookinfx.Nights)<=3) And ((Bookingfx.[Accom Type])="CHALET/LODGE" Or (Bookinfx.[Accom Type])="STATIC VAN") GROUP BY Bookinfx.[Park Name], Month([Start Date]), Year([Start Date]) HAVING (((Year([Start Date]))=2005));
Now when I run this, the first problem is that it asks me for the accommodation type, which is odd as I've already specified this in the query. The second problem is that if I enter say 'chalet/lodge' it returns records telling me that there are bookings for chalets and lodges at parks that only have camping! I have trawled through the database to make sure no erroneous records exist and so I know it is a problem with the query.
If anyone can shed any light on what I've done wrong, I would be extremely grateful! :)
Hello, I am sure this is quite simple, however I cannot figure it out. I have a query that shows tblPartNumber and tblAverage. The average is calculated in the query by taking the total minutes to assemble the parts, divided by the number of parts completed. What I am trying to do is run a query that will show me the most efficient (lowest average), time for each Partnumber. Ideally the query would show me something like this;
Part # Average 1234 .72 1234 .86 1234 .94 etc...
I searched on here and it seemed like the Top 10 is used, but in my application that ommits all of the other partnumbers because it only shows ten of the records for the first partnumber. I only want to see the five most efficient averages. Any help is greatly appreciated.
I have a sub report that is based on a query. The Where clause of my SQL is giving me a bit of hang up. What I am attempting to do is return the records that are the items used to test products we test. The ID's of the records are gathered in a public function. The function is called GetCal Equipment. This returns all of the requested numbers just fine. For example ID numbers 4, 112, 124, 138, 232, 338 are returned when I call the function. Any number of records can be returned at any point. This is the unique numbers used to identify the records. I thought by having the function return the numbers the records would come up. However when I use that in my where statement, none of the records are returned. The whole SQL is as follows:
Code: SELECT CalibratedEquipmentListTable.ID, CalibratedEquipmentListTable.Manufacturer, CalibratedEquipmentListTable.ModelNo, CalibratedEquipmentListTable.Description, CalibratedEquipmentListTable.SerNo, CalibratedEquipmentListTable.LastCal, CalibratedEquipmentListTable.CalDue FROM CalibratedEquipmentListTable WHERE CalibratedEquipmentListTable.ID In (GetCalEquipment());
how to get the query for the report to return the records.
I have a query that I set up to return multiple records. The number of the records is in that text box. I have tried to set the where clause to the text box but for some reason I don't get any of the records I want returned. I am using a Where... IN statement. I have tried to put the numbers in single quotes and no quotes and I have had no luck at all. If I do individual records they will return, just not when I try and do more then one at a time. This query is a part of something more, but since it doesn't return anything, Here is my sql statement
Code: SELECT CalibratedEquipmentListTable.ID, CalibratedEquipmentListTable.Manufacturer, CalibratedEquipmentListTable.ModelNo, CalibratedEquipmentListTable.Description, CalibratedEquipmentListTable.SerNo, CalibratedEquipmentListTable.LastCal, CalibratedEquipmentListTable.CalDue FROM CalibratedEquipmentListTable WHERE CalibratedEquipmentListTable.ID In ([Forms]![ReportForm]![Text41]);
My statement below is current returning 4 records. Two of the records have the same GBPAmount value.
RequestID is the Primary Key
Code: SELECT TOP 3 RequestID, GBPAmount, Currency, RequestDate FROM PayRequest WHERE (((Currency)="CAD Canadian Dollar") AND ((RequestDate)>#11/16/2014#)) ORDER BY GBPAmount;
Code: RequestID GBPAmount Currency RequestDate 10207 8.17 CAD Canadian Dollar 03/02/2015 9874 33.82 CAD Canadian Dollar 20/01/2015 11327 109.58 CAD Canadian Dollar 23/02/2015 10495 109.58 CAD Canadian Dollar 05/02/2015
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
I have a search button / text field on a form with the following code:
Private Sub SearchButton1_Click()
Code:
Dim rsTemp As Recordset If IsNull(Me.SearchField1) = False Then Set rsTemp = Me.RecordsetClone rsTemp.FindFirst "[CompassRef] = '" & Me.SearchField1 & "'" If Not rsTemp.NoMatch Then Me.Bookmark = rsTemp.Bookmark
[Code] .....
Unfortunately it only returns the 'No record found' MsgBox, even if SearchField1 is populated with relevant content.
I am having trouble with the below returning the correct number of records, and can't see why.
I have one table, tblDevice, which has 4 columns, ID | DeviceRecNo | ExcludeFromCheck | StockLocationID
ID - Autonumber DeviceRecNo - Number ExcludeFromCheck - Number (1 = yes, 0 - No) StockLocationID - Number
I have the following running as part of some code, but it is not returning the correct number of records, and I cant see why not. I have tried creating this in a query in Access itself, and copy the SQL into VBA and it still doesn't return the correct number records.
I have 4 records in there for testing, all with StockLocationID = 3, all with different DeviceRecNo, and two each of ExcludeFromCheck, 2x0 and 2x1
Code: Public Function test() Dim db As dao.Database Dim rs1 As dao.Recordset Set db = CurrentDb Set rs1 = db.OpenRecordset("SELECT DeviceRecNo FROM tblDevice WHERE StockLocationID = 3 AND ExcludeFromCheck = 'No'") Debug.Print rs1.RecordCount End Function
I'm running a query from two related tables in the database.the table relationships and the query design. Instead of doing what I want it to do/what I think I'm asking it to - which is show the sum total number of weeks on the program for each student - it shows me the number of weeks for that student just for that claim, not the total for the student overall. I've added some 'dummy data' (2 records in the claim table relating to 1 student), and the query then returns the student twice in the results.
This is a toughie (i think so anyway!). I'll attempt to explain!!!
I start with a CONTINUOUS form in my DB that shows all readings for a single given customer's connections. E.g. Customer A has 5 connections and each connection has say 3 readings. Thus this query which uses joins between the Customers, Connections, and Readings tables, would return a list of all readings for each connection, so in the above example: 1*5*3 = 15 records.
Not too tricky so far, but then what I want is for each connection to have just one line showing the latest reading (easily achieved by use of SQL Aggregate Max function on the date field coming from the readings table) TOGETHER WITH the last-but-one (next most recent) reading. So back to the example taking Customer A's connection 1, the row would be as follows:
Cust Conn CurReading PrevReading A 1 750 500
Where the CurReading value (750) comes from a different record than PrevReading (500).
I've tried all sorts of ways (subqueries etc.) to achieve this without success. The main problem being that any sub query would require parameters from the current record's fields, which seems not to be possible. Can anyone help or is this simply not possible in MSAccess Forms. If it isn't possible anyone have any suggestions as to an alternative way?
It is basically a DCount, and it should find records, but returns 0 all the time. My code is:
Code:
Function cntkit(sftd As Date, sftn As String, typid As Integer, specpaint As Boolean) As Integer 'Counts jobs kitted during shift given by sftd and sftn Dim timeformat As String timeformat = "#mm/dd/yyyy hh:nn:ss#" 'need this, to convert it to US datetime format cntkit = DCount("[JOB]", "Archive", "[Type] =" & typid & " And [Autfinish]=False And [SpecPaint] =" & specpaint & " And ([Kit] BETWEEN " & Format(sftstart(sftd, sftn), timeformat) & " AND " & Format(sftstart(sftd, sftn), timeformat) & ")") End Function
sftstart and sftend are functions which are returning dates. The funcion works fine if I omit the Between part of the criteria. So the problem is in that part.
I'm creating a search form to filter out data based on certain inputs. My VBA code looks like:
Code: Private Sub Command18_Click() On Error GoTo errorcatch Me.Filter = "([Experiments.Log] Like ""*" & Me.Text21 & "*"") AND ([Expdate] Like ""*" & Me.Text22 & "*"") AND ([BaseSolution] Like ""*" & Me.Text24 & "*"") AND([AddCom] Like ""*" & Me.Text25 & "*"") AND ([Test] Like ""*" & Me.Text26 & "*"") AND ([Plan] Like ""*" & Me.Text23 & "*"")"
Me.FilterOn = True Exit Sub errorcatch: MsgBox "Error #: " & Err.Number & vbCrLf & vbCrLf & Err.Description End Sub
However, the output does not include records where other fields are blank. I have read that I may need to use Is Null but am not sure how to.
