In access 2010:
I have the table "pharmacy" and I have a field called "ph_quantity".
I also have the table "warehouse" and I have a field called "wh_quantity".
In "warehouse" I also have a field called "available_stock".
Whenever I will change "ph_quantity" or "wh_quantity", I want to automatically update the value of "available_stock".
Any help please?
There are two new features in MS Access 2010 that should be of use to you.
In Access 2010, you can create table fields that calculate values. The
calculations can include values from fields in the same table as well
as built-in Access functions.

I'm trying to create a database in Access 2010, and have run into a bit of a problem. I currently have two tables, EarlyStageListResults & ESDailyTotals. Each of these tables has a field named Records, with ESDailyTotals being a summary of multiple entries in EarlyStageListResults. What I need to do is have the Records field in ESDailyTotals be the sum of multiple Records fields in EarlyStageListResults. For example, given the following records in EarlyStageListResults:
Date Records
4/22/16 2000
4/22/16 3000
4/22/16 1500
4/21/16 1200
4/21/16 2700
the records in ESDailyTotals should be:
Date Records
4/22/16 6500
4/21/16 3900
I know this can be calculated later through VBA and a form event, but optimally I'd like to be able to have it update as soon as any of the Records fields in EarlyStageListResults changes. It looks like there may be a way to do this using the Access Macro Editor (not sure of the name, but the tool where you can create a macro through a series of combo boxes rather than through VBA), but I've never gotten an understanding of using that tool, so have always relied on Forms and VBA instead. Basically if there's an event that triggers when a field is updated, and a way to enter VBA code into that event handler like you can with Access Forms, then I can do it with either DLookup or an SQL statement I think, but I don't know how to grab that event handler.
This does all need to be done within Access itself, I can't use an external program to update the records in an Access database file. This is for work, and (officially at least) any custom programs are a big no-no. :)
Thanks in advance everyone!
You're making this way too complicated. You just need one table and a database view (called a query in Access, I think) that is defined as
select Date, sum(Records) as Records from EarlyStageListResults
group by Date
Name the query ESDailyTotals.
How to make the default value a reference to a field from another table while still being able to edit the new field in Microsoft Access?
Ideally, I’d like to find a solution that doesn’t include the use of VBA coding.
If you have Access 2010 or 2013 you can use the macro event "After Insert Macro Event"
Here is the official description from Microsoft
https://msdn.microsoft.com/en-us/library/office/ff196099(v=office.14).aspx
You should examine the Example and build an appropriate version in your database for your needs.
I'm trying to figure out if there is any vba way of sorting a report field in access 2003. I have this field that contains three different values " Estimated date", "Needs date" and "Date in"; what i need is for the field to be sorted first from A-Z and then by Date. If anyone knows how to do this in either VBA or access2003 please let me know I'm fairly new to access and vba so any help would be greatly appreciated.
For an Access report, use the report Group and Sort option to define your sort order. That option over-rides any sort order established by the ORDER BY clause in the report's record source query.
I don't recall exactly where that option is found in the Access 2003 user interface, but suspect you can track it down. Meanwhile be aware that Microsoft will discontinue support for Office 2003 in April 2014.
Here is a screenshot from Access 2007 which shows where the option is located on the ribbon interface.
Yes, go to the queries tab and create a new query based on your table and sort on those fields. Then modify your report to read data from the query and not directly from the table.
If this is not the forum to ask this question, please direct me to the correct one.
I am trying to learn Micosoft Access 2013 programming. I am trying to create a report on a form to display the table info based on a user defined range of the creation date. How would I go about doing this? Is the creation date stored automatically, available for retrieval?
No, Access does not automatically store the creation date of a record. However, you can accomplish that by adding a Date/Time field named [RecordCreated] (or whatever) to the table and setting its Default Value to Now(). That won't add a timestamp to existing records, but new records will automatically have their creation date (and time) recorded.
In Access, when I do a Database Tools->Database Documenter, and document an existing table, the report has a value called GUID. I want to get that GUID programatically.
I am trying to determine if 2 databases came from the same source, by comparing their GUID.
Points for either telling me the name of the function; alternately, you could tell me how to decompile the code that generates the report.
At least on Access 2010, the GUID value is in the "Properties" section of the Database Documenter report, so I tried this out in one of my databases:
CurrentDB.TableDefs("dateTest").Properties("GUID").Value
The return value is an Array of Bytes.
The value can be found in the system table called MySysNameMap
SELECT GUID FROM MySysNameMap WHERE Name = "Your TABLE NAME"
You can also use function such as DLookup in VBA to get the GUID from that system table.
