This is a simple SUMIF in excel, but my dataset is too large for excel.

Queries :: Update Query To Replace Number With Text

Apr 15, 2014

I've made a simple form to Login/Logout with radio buttons but the buttons only allow me to push a number as a value, in my case 1 or 2 for Login or Logout.

How would I make an update query to change those numbers to the equivalent text? Or is that not possible in the same field because that is 2 different data types?

Reports :: Row (Line Item) Number On Report

I want to have line item numbers on report look like this:

Number....Order Number

5............7392-2305-62 ->repeating item

Each new row of record needs to have their own line item number starting from 1 with criteria if order number is the same then carryover line item number on that record. I know how to get line item starting from 1 to last by assigning unbound control field with entry "=1".

Queries :: Access 2007 - Update A Field In A Table With A Random Number / Long Integer

May 27, 2014

Is it possible to run a SQL command to update a field within a table with random numbers?

More specifically - random long integers linking back to an ID (autonumber) field in another table?

Background to this is, I have multiple static data tables related to each other by long integer identifiers (autonumbers)

The structure is fine but I haven't been provided with the actual data yet - but for development purposes, I need to work on other functionality which requires that this data be present.

So I want to fill my table with dummy data such that I can go off and work on the remaining functionality, but then just go back and clear it all out once I get the actual data.

I have one 'main' static table, which links back to other tables, which I have already populated with dummy static (i.e. company names, locations etc) Now I want to go into my main table and populate those fields in each record with a random ID. I don't mind doing this field-by-field (there's only a handful) but I've a lot of records in there (~1000) so I'd rather not do this record-by-record.

General :: Select Item Number From Drop Down Box To Create A Report

Jun 27, 2012

I'm currently working on fixing an older 97 database that I've updated to 2010. I have just populated the Drop down box with about three fields. Ideally what I want to do is after having selected the item number from the drop down box I then hit the button that creates a report with the information about that item number.

At the moment...If the box is blank it reports all the item numbers, however if i fill the box(select an item) it returns nothing i.e the report is blank.

I've looked at the query that builds the report, there are only three fields that populate the. location, part number and description. from a tbl called MainDetails

the only other thing:
If([Forms]![frmReports]![FLoc] Is Null,[FUNCTIONAL LOCATION] Is Not Null,[FUNCTIONAL LOCATION] Like [Forms]![frmReports]![FLoc])
it has a criteria of <>False
*FLoc is the drop down box *functional location is the location field.
I believe all the above does is populate the report if Floc is empty.

What can I put to make the report generate what ever I pick in the drop down box 'FLoc' source the three fields from the 'MainDetails table'.

Reduce Multiple Records To One

Jun 28, 2007


I hope you donít mind my using this forum as a learning tool. I am running an Access 2007 database. I am trying to create a query from 3 tables:
TblTrainingPrograms containing the following fields
Program Number (unique value)
Program Title
Program Date

TblInstructors with these fields
InstructorName, address, etc.

TblInstructorProgram with the fields
ProgramNumber(linking this instructor to a particular training)
InstructorNumber(in the case of multiple instructors for the same training, the user may add new records and enter ď1Ē, ď2Ē or ď3Ē here)

I need to run a query that will display even multiple instructor programs in one record, so that Instructor# 2 will appear in another field in the same record rather than having 2 or three records displayed in the datasheet view. Iíve tried several combinations, but when there is only one instructor, the Program does not appear in the query results.
I donít really know a lot about SQL, but Iím hoping there might be a way to do this that way. Any help would be appreciated.

Thanks in advance,

Setfocus On Repeating Item/accessing A Specific Item

Aug 18, 2006

I have a form that simply lists the items:

In the table: DEPARTMENT_TBL

When I edit the field DEPARTMENT_NBR and it is in error (must be between 01 and 99) I want to put out a message in a MSGBOX and SetFocus back on the DEPARTMENT_NBR.

I coded the MSGBOX with vbokonly and then DEPARTMENT_NBR.SetFocus, but after the message displays and enter is hit for the ok the cursor jumps to the DEPARTMENT_NAME on the current line. Is there a way to get the SetFocus to work properly on repeating items like this? I can never seem to get them to perform the same as they do on non-repeating items.

Thanks for your help.

If IsNumeric(DEPARTMENT_NBR) = False Then
If DEPARTMENT_NBR <> "00" Then
MsgBox "DEPARTMENT NUMBER must between 01 and 99.", vbOKOnly
GoTo DEPARTMENT_NBR_EXIT (exits the paragraph skipping other checks)
End If
End If

Also, is there a way to look at a specific item in a list like that? IE. I want to reference the 3rd row's DEPARTMENT_NBR. Thanks.

Reduce Decimal Places WITHOUT Rounding

Feb 15, 2006

Hey everyone! Hopefully, someone can help me with this. I've searched the forum and can't find anything on it.

I want to take a number and reduce the number of decimal places from 4 to 3 WITHOUT rounding it. Just chop off that 4th number...I don't care about it.


243.4586 = 243.458
22.0541 = 22.054
5.8577 = 5.857
1,587.2556 = 1,587.255

Seeing as how the numbers can be in the 10's, 100's, and 1000's, I can't just use the LEFT function. :D That, of course, would be too easy.

Suggestions? Solutions?

Thanks in advance!

Queries :: Unable To Select Item From Combo Box

Feb 2, 2015

So I have this form with a combo box which successfully displays a range of items from which I would like to select from - but unfortunately I cannot. I cannot select anything from the combo box.

I have checked the form and table to ensure I have edit rights - which I do.

The form is based on a query - attached is a picture of the relationships within the query.

I assume I have created a non updateable query but this is only an assumption.

I am lost about the best course of action to take. Is there a way to identify the problem?

Do I just cut my loses and recreate the functionality somehow?

Queries :: Get Information From Selected Item Of ListBox

Nov 22, 2013

From a search form example I got from this forum I made the following:

A listBox which shows results as you type, using a query.

This listBox has 1 column, I need it that way.

What I need is to show the information from the selected item of the listBox on a textBox, getting this info from the results of the query.

I found 2 answers which I don't like:

1- =DLookUp("[Column]","[Query]") as source of textBox

This shows only information from the first row. So if you select the second result from the listBox, it still shows the first row.

2- =SearchResults.column(int) as source of textbox

It does not work, because listBox has only 1 column.
