Queries :: Name A Field In A Query Or A Table With A Variable Name?
Jul 19, 2014
is it possible to name a field in a query or a table with a variable name?
For example:
I want to choose in listbox "fieldname" the name of the field.
And the query field name looks like:
Code:
forms![testform]![fieldname]: FieldOfTheTable
Unfortunately it doesn't work.
Also if I save the choosen fieldname in a vba function.
Code:
fieldNameFunction(): FieldOfTheTable
This doesn't work, too.

In my access form I provide the user a list of locations from various countries in a listbox . But the list is too long so I provide him a combobox for selecting a country. Selecting the country should update the listbox showing only the locations in that specific country.
So my SELECT from the listbox must cover the unselected state and show all entries and when a country is selected it must narrow the selection.
I tried to get this happen with the following SELECT statement containing a variable. Choosing a country in the Combobox results in a change of the variable and in a requery. This works after the first country is selected and for each country change, but the initial list is empty.
VBA in the loadform
'Application.TempVars.Add "varcountryselect", "*"
SELECT in the listbox "lstlocationsperproject"
SELECT tbllocations.locationID, tbllocations.country, tbllocations.localstreet, tbllocations.localcity FROM tbllocations WHERE ((tbllocations.country) Like [TempVar]![varcountryselect]);
VBA in the combobox
Application.TempVars("varcountryselect") = [Form]![kombcountryselect].Column(0)
Me.lstlocationsperproject.Requery
The values in [kombcountryselect].Column(0) are texts like "SPAIN", "MEXICO", etc.
Any hints, how I have to use the * for getting the complete list on the initial view ?

I am creating a 2 level report to confirm an order. Main report already created, runs successfully called as subform/subreport under "OrderDetails" form. Linked to master using Order.ID. There are two versions of the confirmation report that have different layouts for different program types.
The hangup comes when I try to add a "Class Dates" subreport. It lists dates of individual classes and Skip dates. I have created the subreport as "srClassDates". When I add it to the main report, it lists the records. However, when I try to link it to the Main report, an error message box appears with the "object variable or With block variable not set".
I have tried rebuilding both the main and subreports, rebuilt the query, have not found anything that changes the result.
Linker has been working successfully on other subforms. Report with groupings works fine, but I need data from 2 tables both linked to order.id.

I have a query that has three fields: 1) Days 2) Bit Size 3) Feet. The Days field has a date range specified in the Criteria that comes from two unbound fields on a form. I have a second query based on the first: Two fields are Days with the Total as Min and Max. Three fields are Feet with the Total as Min, Mac, Avg. One field is Bit Size with the Criteria as a specified bit size (i.e. 6.125). These queries are used on a report, and all data is inputted from forms prior to the report.
The queries work as expected with a specified bit size. My problem is that while Bit Size is normally chosen from a list of sizes, a custom size can be inputted. I am unsure how I can specify the Criteria in Bit Size to be a custom size..? To compound things further, more than one custom size can be used.
A) I need a way to pick out the custom sizes from the first query and B) use them as the Criteria for the second query. If I use VBA, I assume I could complete B) by using a WHERE clause (if the custom size(s) has been defined)...

Im trying to pass a list box variable in a select query. I understand you cannot pass a variable directly but have to pass it through a function. I may be wrong in this, but whatever I do I cannot get it to work. Here's my code:-
Public Sub GetEquipment()
List387.RowSourceType = "Table/Query"
List387.RowSource = "SELECT findequipstr() FROM Equipment"
End Sub
Public Function findequipstr() As String
If IsNull(List371.Value) Then GoTo function_end
findequipstr = List371.Value
function_end:
End Function
If I MsgBox(findequipstr()) within my Getequipment function, the variable is messaged,

I wan't to create special query who show only special package. It must work that.
1. Client logg in. System rember his chose. varPrawa="Client" and varIDLogin=5
2. Client click at button "Show Your Package". At that moment query haven't got any criteria so it show every package but it must show only package with IDClient=varIDLogin so only package with IDClient=5 it is easy to create. I tell more it is still easy to join other person but only with varPrawa="Client" i want to create one query who must select by.
WHEN varPrawa="Client" then show only package with IDClient=varIDLogin
WHEN varPrawa="Kurier" then show only package with IDKurier=varIDLogin
WHEN varPrawa="Spedytor" then show only package with IDSpedytor=varIDLogin
WHEN varPrawa="Administrator" then show all package without varIDLogin criteria.
I create subraport who use chosen package in my list and display all special data using varaible but my problem is how to create query whose can select and display only package of that Client or Kurier or Spedytor.
At the end
When Client is online he can see only his packages special IDClient (any IDKurier, IDSpedytor)
When Kurier is online he can see only his packages special IDKurier (any IDClient, IDSpedytor)
When Spedytor is online he can see only his packages special IDSpedytor (any IDClient, IDKurier)
When Administrator is on line he can see all packages (any IDClient, IDKurier, IDSpedytor)
How i can create this query?

I am trying to use a criteria to filter out nulls in concatenated variable, which slows the query considerably.The part that makes it slow looks like this -
WHERE ... AND (([tbl1].[x] & [tbl1].[y]) <> "") AND ...
If I work them individually, it's not a problem, the query is fast, but I have to combine them first in order to produce the correct output.

I am trying to copy the parameter value that is entered to a variable so that it can be used to run other queries without typing it in over and over. Once my form is finished it will run 4 queries, and the current setup is that I would have to retype the parameter each time.

I am trying to create a table to show the parent/child relationships between assemblies, sub-assemblies and detail parts. The table I start with has 2 fields a "Part Number" and an "Indenture".
Please forgive all the periods, couldnt think of how else to seperate the values to depict the tables.
Example:
IND..PN
00....A
01....B
01....C
02....D
03....E
03....F
01....G
00....H
01....I
02....J
I can get the first step to completeing the new table of parent/child relationship like this:
PN....00....01....02....03
.A.....A
.B....."".....B
C......"".....C
D......"".....""......D
E......"".....""......"".....E
F......"".....""......"".....F
G......"".....""......""....G
H......H
I......""......I
J......"".....""......J
Where "" are null values
My problem is making it so that every part number has its own array, aka [family tree], so that for part "F" the table would hold "A,C,D,F"
I though an update query where for example:
*"Zero" is a single field string.
IIF([00]<>null(), Save [00] to Zero, Write Zero to [00])
Would work but have been unable to find any information about passing a field value to a variable for later use or comparison. I would have already done this in excel if the table had less that 65000 records.
Example of final table:
PN....00....01....02....03
.A.....A
.B.....A.....B
C......A.....C
D......A.....C......D
E......A.....C......D.....E
F......A.....C......D.....F
G......A.....C......D....G
H......H
I.......H......I
J.......H......I......J
Any help is greatly appreciated.

I want to set a table field's default value to whatever is displayed in a certain field on a certain form at the time.In other words, say I have a database with a table called TABLE1, and two fields called NAME and SCHEDULENUMBER. I have a form called CreateSchedule with a SCHEDULE NUMBERCONTROL form and a NAME form, and I can enter names onto it, and it records to the proper SCHEDULENUMBER. So if I pull up SCHEDULENUMBER 4, and add three names, when I go back into TABLE1, I can see those three new names, and each one has the SCHEDULENUMBER set to 4.
What I'm trying to do is write an APPEND QUERY to copy a list of names from a different table, and paste them into TABLE1. The problem is that the other table doesn't have a SCHEDULENUMBER field. What I want to do is put a button on the CreateSchedule form that runs an APPEND QUERY, and sets the SCHEDULENUMBER to whatever value is displayed on CreateSchedule's SCHEDULENUMBERCONTROL field.
I tried setting a default value in TABLE1's field properties for that SCHEDULENUMBERCONTROL field, but I keep getting error messages. I just want TABLE1, whenever I add a new record (regardless of how I add the record: manually typing it or clicking the append query button) to look at the form CreateSchedule, and set it's own SCHEDULENUMBER field to whatever is displayed in CreateSchedule's SCHEDULENUMBERCONTROL form.

I have a query with many fields. One of them is the combination of two fields and is called "Components Reference". What I try to do is, every time this query is updated, the records of only this field "Components Reference" to be written to the field of another table which also takes records from an another query. I wish I was clear enough.

Users are viewing a record on a form that gets it's data from a query. I want to make it so that if they edit that record from that form, a last updated field will timestamp the date/time that the record was edited. I added a lastupdated to the source table which of course adds it to the query and so it's on the form.
But whenever i access the form and change something, the lastupdated only shows the time the record was created (which is from a different form based directly on the table). Whenever I edit any other field data in that query based form it changes in the table. Why not the Lastupdated?

I'm using Access 2003...I have a query that searches a parts table by description:
Like "*" & [Enter in Part Description to search] & "*"
I need to add another search to this query, I added another field to the parts table call manufacturer. I add this field to the above query and added this parameter to it:
Like [Enter in Manufacturer] & "*"
I then added a manufacturer to one of the fields for test purposes. For some odd reason this doesn't work. If I take out the manufacturer parameter and don't enter in anything into the part description the query returns all the records. When i type a description into the part description field the query returns the proper records. When I add back the manufacturer parameter and enter through both parameters only the one record returns showing the test record instead of all of them. If I put a part description in and enter through the manufacturer parameter no records show when they should.
I've tried adding a test field to a different table and tried a different query using the like parameter. The parameter works in a field already in the table but won't work with the new field I added. I've done compact and repair.

I have a created a query which I want to update a table. The field is called DTP. I have the Workingdays2 module in place as well as the Holidays Table. The dates (date only) are called Time in and Transaction date. I want the table to update records only if the entry in Completed is Yes. I have attached screenshot of what I have in query. I am no good whatsoever at VBA so I used the Query design view. It shows how many records will be updated (which is a valid number) and shows me which field will be updated. However when I run the query and then opend the Table the DTP field is empty.

Let's say Table (T1) has fields F1 and F2. After a massive update to T1, there are some records with F1 = "" because a Dlookup using F2 as criteria to another Table (T2) resulted in a null. I created a select query to show unique T1F2 values where T1F1 = "". The user can use this query to find out which F2 values need to be added to T2.
How do I create an update query that will update T1F1 with values from T2 using the T1F2 results from the select query to again use the Dlookup to T2 (of course after T2 has been updated to contain the missing F2's)?

I have a single table with customer information, one of the fields is a date field "LastContacted".
I'm creating a search form with 2 date fields (txtDate1 & txtDate2) to search a date range of the LastContacted field, and I need to write this into the query that the search form uses.
I have written this using Nz so that it can still return results if the search boxes are left blank:
Between Nz([Forms]![frm_AdvancedSearch]![txtDate1],#01/01/1989#) And Nz([Forms]![frm_AdvancedSearch]![txtDate2],#01/01/2999#)
This seems to work and it returns lines from the table where there is a date entered. However some of the fields in the table have no entry in the LastContacted field. How to code this query so that it also returns lines where the LastContacted field is blank in the table?
I have tried:
like "*" & (Between Nz([Forms]![frm_AdvancedSearch]![txtDate1],#01/01/1989#) And Nz([Forms]![frm_AdvancedSearch]![txtDate2],#01/01/2999#)) & "*"
but this returns errors when I try to run it.
I'm using Access 2010.

I am just querying a single table, no relationship involved with another table. As you can see form the attached jpeg, the ZIP field in some cases is empty. I would run a search using Is NULL but the field is NOT numerical. It's a long story but I had to make this field a TEXT field. Basically, what statement do I have to insert in the criteria field to just pull up the EMPTY ZIP fields?

My computer has been updated to 2010 whilst I've been off sick (was 2003 before my accident).
I've created a main table, for devises across the company, and a combo box/selection box based on another table which holds a list of all the "Responsible" employee's aswell as another combo box/selection box for the device location.
So the person entering the information, can enter all the information for a device (torq wrench, socket set etc), who is responsible for it and which department they belong to (where to find the device).
Which all works fine
However, I'd like to create 2 queries, one to enable the user to run a report of all device's allocated with an employee or to be able to run a query for all device's stored in a particular department.
But I have been unable to set the correct query criteria, to enable to query user to be able to selection from a drop down list, which responsible person or location to pull back the correct list.
I was getting an error asking me to set the parenthesis, I have now deleted criteria for both queries, as even if I put [Enter] and type a Responsible person's name exactly as its held on the table, the report comes back blank.

I've tried simply the following, but get a "No current record" error. why I'm getting the error, but how do I select the record currently visible in the form to edit?
Code:
foo = "bar"
