Populating A Column In A Table Based On Values In An Existing Column

Mar 5, 2007

Hi all,

In the organisation that I work for employees get paid every 2 weeks on a Saturday. So for this financial year the pay period end dates have been 08/07/2006, 22/07/2006, 05/08/2006 etc


I have a column in an Access table listing various dates. I want the next column to be
populated with the next pay period end date after that date.

So if DATE is 05/07/2006 I want PAY PERIOD END to be 08/07/2006
and if DATE is 09/07/2006 I want PAY PERIOD END to be 22/07/2006 etc

How do I do this?

Kind Regards,

Matthew

Forms :: Populating Null Field In Form From A Different Column In Same Table

Sep 15, 2013

I've been trying to populate a field in a form with information, but only if the field is blank.

What I am trying to do is this.

I have a continuous form displaying all of our principals, however when our principals are on leave I want to populate the field with the "acting principal". I have set it up so the field grabs the acting principal first but it is blank for several schools. For these schools where there there is no "acting principal" I want it to grab the substantive principal automatically and populate the field.

I have tried Is Null, Is Not Null, NZ, IF, Where and Then statements but to no avail.

Modules & VBA :: Switch Function - A Null Makes Whole Column Null

Nov 16, 2014

I do not understand what is happening here. I have foll0wing line in a calculated query field:

m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010

this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.

But if I do this:

m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example

then the entire column is set to Null

Queries :: IIF With Null Included Field - Lookup Table Values

Jul 1, 2013

I am currently working on an instrument datebase, I have a mainquery that takes care of user inputs from a form. The main fields that have been queried on are Type, System, and Manufacturer and they are all look-up fields that contain some null values.

On the same criteria row for these fields, I have

Like IIf([forms]![User Interface].[qtype2]="","*",[forms]![User Interface].[qtype2])
Like IIf([forms]![User Interface].[qsys2]="","*",[forms]![User Interface].[qsys2])
Like IIf([forms]![User Interface].[qman1]="","*",[forms]![User Interface].[qman1])

qtype, qsys and qman are the user inputs from the user interface that returns look-up table values.

This works fine when all 3 of these fields are all filled out for a certain instrument. The problem arise when some fields of the instrument are left blank or is null. The instrument won't show up in a query at all. What I wanted it to do is to show everything including the ones with null fields when the user input are null or "". When the user specifies certain requirement I only want to show the ones that are not null. I understand that putting them on the same row means AND, I have tried to OR them and did not have the result i wanted.

Match The Sum Of Column Values To Another Table

Jun 12, 2015

I am using access 2010. I have "classlevel" table with 2 columns-Class and Value1 .Value1 column has numeric values that i ll input from webpage (webpage to ms access connectivity).I want to sum the values of column "Value1" and i have another table-"Volume" which has 2 columns "VolumeLevel" and "Value2". So i want to match the sum that i calculated from first table-"ClassLevel" with the "value2" column in "Volume" table and get the corresponding "volumelevel" column value from that table and there is a third table that will get this volumelevel value.

There is no common column to join these tables.

Classlevel-

Class Value1
Class 0 3000
Class 1 2000
Class 2 300
Class 3 400
Class 4 500

Volume-

Volumnlevel Value2
Vo 0
V1 5000
V2 10000
V3 30000
....upto V10

Tables :: Setting Primary Keys To More Than One Field In Table / But They Cannot Have Null Values

Nov 30, 2012

Access 2010..One organization that we work with provides us with a block of numbers for each of the two types of contract products we order from them; we do order non-contract stuff from them also.The block of numbers are the same (i.e. 20000 to 30000 this year) for each of the two products. This means that each product can have the number 20000, for example. We call this the Tracking Number. If it is one of these products, we need to select the Contract Number.

For all other one off orders we have with them, we assign our own Tracking Number starting with 00001. This Tracking Number cannot duplicate unless it is one of the aforementioned two products.Both the Tracking Number and Contract Number are in the same table. The user selects the Contract Number from a form (connected to the Contract Number table that has all the details on the contract) and the Contract Number is populated in the same table that has the Tracking Number.Each order must have a Tracking Number (no null)..Not all orders need a Contract Number (null okay).The Tracking Number and Contract Number combination cannot duplicate.I tried setting the primary keys to more than one field in the table, but they cannot have null values.

If not... I have been working on Plan B.... an AfterUpdate on the form (either the form or a field... don't know yet) that looks at a query that only has results if there are duplicate values.

Forms :: Combo Box With Different Column Values To Create A Table

Jan 17, 2014

Am I correct in thinking the only way to have a combo box with different values in each column is to create a table and then bind the combo box to the column you are referring to if you want it to represent a value from another.

For example if I have a combo box with the words January, February etc can that combo box have a corresponding month number value in a separate column (this combo would be derived from a list) or would I need to create a table holding both the month names and numbers and then bind to the name value for selection but use the month number value?

The reason I ask is I wasn't sure if for every type of list I wanted with multiple column values, I would need to create a table.

Modules & VBA :: Wildcard Search Of Combobox - Lookup Values In Table Column

Nov 19, 2014

I have a form which has a combobox called Task_Ref which looks up values in a table column.

I would like to be able to set the tickbox value of tickbox called P1 to True if the combobox contains the word "test", each entry on the combobox selection may vary such as:-

Test number 1
Yesterdays Test

As long as the word "Test" appears I would like the above to happen?

I was thinking of something along the lines of:-

If InStr(Task_Ref.Value, "Test") > 0 Then
P1.Value = True
Else
P1.Value = False
End If
End Sub

But this hasn't worked

Field Criteria: Is Null; There Are Null Values In That Field; No Records Are Returned

Nov 16, 2007

I think the title pretty much sums it up....

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.

The query is refusing to return any results...

Any ideas?

How To Filter On A Column That Sometimes Is Null?

Aug 14, 2006

Hi!

I want to be able to filter a form based on a dropdown box, where one of the items can be null. (The field is of type short date).

the dropdown box is named "Fltr1".

The form is based on a query, and i have tried to express the filter in the query like this (sql syntax):

([Tablename].[Columnname]) Like "*" & [Forms]![frmMyForm]![Fltr1])

But this way, the records with this column being null are omitted...

I very much appreciate any help that leads me in the right direction ;)

Last Non Null Record In Column

Oct 14, 2015

Okay so I have a column called 'totalincome' on TblCashflow. There are 60 records of TotalIncome (represents 5 years or 60 months) per asset that I have on another table, TblLoanGeneral.

What I need to return is the LAST value from totalincome that is not null. For example, we may only have entries in the 60 records that go to row #35, or 50 or whatever. When I use the Last criteria it gives me the 60th record (in example would give me a 0), and when I use the Max criteria, it gives me the largest income value regardless of location(would be 50,000 in example). What I need is really where the "last" income amt is >1 (20) however, when you set last, it only considers row 60.In the example below I would want 20 to be returned.

ID
Row#
TotalIncome

Queries :: Pull From A Second Column If The First Is Null

Aug 6, 2013

I have 1 query that connects 4 of my tables through a tracking number. I am trying to make it so the value (DStatus) from DTable will populate where a (DStatus) is provided, but where there is no (DStatus) the column is filled in with a (SStatus) from STable. There is always a SStatus for each tracking number, but not always a DStatus, where there is a DStatus, it is more accurate.

Can I do this all in 1 query, whether I have to make a new column within my query for this to work, whether I need to have my query output into a table first.

Is there something I could type into the Criteria field of my query.

I have tried using Nz([DStatus],[SStatus]), an Iif Statement, the IsNull function, etc with no avail.
