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...
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?
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).
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
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";"")
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)
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 form that feeds information to a query which in turn sets up a report. For clarity i will list out in basic terms what I have
Input Form - Check Box to activate/De-activate a text field [chk-active] - Text field for a parameter [txt-Parameter]
the query has a column that has null values from the originating table. These values will be added a t a later date, but need to be queried and reported at some business intervals.
In the query criteria for this column, I have the following Criteria
Like IIF([Forms]![ReportGenerator]![chk-Active]=0, "*", [Forms]![ReportGenerator]![txt-Parameter])[/I][/I]
I have tried for the last 5 hours to figure out how to write the formula to be able to get the blank entries to show up as well but have had no luck.
I have a Membership List Table with a calculated field entitled Member Name.
The second table entitled Groups contains only 46 records each of which has up to 30 Fields also containing member names.
I Have written a query to establish which of the members from the single field of the first table do NOT featured in any of the fields and records of the second table. In the Query Design View I have listed 'Member name' from Table 1 followed by all the relevant member fields from Table 2, carrying the criteria 'Is Null'.
When I run the query, it merely lists all the members from Table 1.
I've built a form on my Access database that invites a user to enter a start date and an end date into two textboxes. When i press a command button, a parameter query runs which uses the two textboxes as the parameter's criteria. However, to ensure that both textboxes have a data entry, i have tried entering in some VBA that prompts the user to enter in a date if its left null...then set focus to that textbox: Here it is...
If IsNull(Me.txtWeight1) Then MsgBox "You must enter a minimum weight!" Me.txtWeight1.SetFocus Else If IsNull(Me.txtWeight2) Then MsgBox "You must enter a maximum weight!" Me.txtWeight2.SetFocus Else If IsNull(Me.txtWeight1) And IsNull(Me.txtWeight2) Then MsgBox "You must enter a min and max weight!" End If
This will not compile for me! I've tried with and End If and without an End If and other stuff. Why won't it work?
I have a table in access which is updated weekly; I need to create two tables from this updated table.
1st table will consist of all the new entries for the current week
2nd table will consist of all the entries from the previous week - an amalgamation of all the entries which are not from the "current week" (table) For example; the table below shows the two entries from last week.
ID Name
1 Adam
2 Ben
This week I have three new entries New entries
ID Name
3 Charles
4 Richard
So when I run the same query next week I will get something like this.
Old Entries ID Name
1 Adam
2 Ben
3 Charles
4 Richard
[code]....
How do I get a query /queries which divides up the weeks new entries and also all the old entries.
It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code: Private Sub cmdUpdateDates_Click() '################################### 'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time]. '################################### Dim intCounter As Integer intCounter = 0 Dim rs As ADODB.Recordset
I am having problems with setting up a set of combo boxes.
What I am trying to do is if combo Productline is empty then in combo PartNumber would show all products but if combo Productline has a value selected then in the combo partnumber would only be able to select the partnumbers in that productline.
Hi, I have some problem with assigmnet with date and string variable. what i wana do is get data from Forms textboxes into variable and then by insert query send to history table.
the problem occurs when there is blank textbox its says invalid use of null.
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.
Notes (1 to many relationship with People table, based off Number) ----- Number (lookup to People table) Note Date
I need to take all people of a certain type whose newest note is more than 6 months old. Here's what I have so far (it doesn't take into account the "more than 6 months old" part). Notice that I have the GROUP BY because of the MAX() in the outside SELECT statement: SELECT [App Info].[First Name], [App Info].MA, [App Info].[Last Name], [App Info].[Soc Sec #], [Note Info].Note, Max([Note Info].[Eff Date]), [App Info].[App Type] FROM [App Info] INNER JOIN [Note Info] ON [App Info].[Soc Sec #] = [Note Info].[Soc Sec] WHERE [App Info].[App Type] Like 'Apprentice*' AND [Note Info].[Eff Date] in (SELECT [Note Info].[Eff Date] FROM [Note Info] WHERE [Note Info].[Eff Date] Is Not Null) GROUP BY [App Info].[First Name], [App Info].MA, [App Info].[Last Name], [App Info].[Soc Sec #], [Note Info].Note, [App Info].[App Type];
Problem is, it's returning multiple notes for a given person.
The snipet below returns only a single record. I want all the records. I am not sure how to get the results from the query or the syntax.
This is what I want:
Select location from client_loc where clientID = FORMS!job.ClientId
Thanks ---------------------------------
Private Sub ClientId_AfterUpdate() GetValidLocations End Sub
Private Sub GetValidLocations()
Dim varName As Variant ' declare a variable for the name
' Check if either combo box is null If (IsNull(Me.ClientId)) Then varName = "" Else ' Look up the title varName = DLookup("[Location]", "client_loc", "[clientID] = FORMS!job.ClientId") End If
If (varName = "" Or IsNull(varName)) Then Me.location = "(None found)" ' Otherwise, put name into the text box Else Me.location = varName End If
Hi anyone! I have a table that tracks data for parts across different depots. Thus some depots might not have records for a part in a particular depot whilst others do on a given day. My table does not record a 0 value for parts in a dept that don't have a part on a given day, it simply does not record anything.
I would like to query all depots and have it return a 0 value where there are no records on a given day for a given part in that depot. Does anyone know how to do this? i.e. if no record return 0 as default.
Does anyone know how to do that? At the mo my query simply exlcudes all records on taht day for all depots?
My select works fine when I select 3 fields, but trying to select more than three, when I add two fields more, it doesn't give me the last two fields, being these two fields added lattely in the table...
I mean... I added two fields more to the table one it was created, and the script executed. After that, if I try select * from table, the recordset does not have this two fields... only the old ones...
