So I am creating a database to track projects. In it I have several milestones. On the form each milestone has a label and a textbox next to it. The project manager will go in and type the date of that milestone.
What I need to do is based on the textbox that date is typed in it will save date and milestoneID to a table.
If you look at the Form and Table images attached:
You see on the form they enter the date next to milestone.
On the table you see the each date gets a schedule ID (autonumber), the projectID gets assigned to it (another table), and then the milestoneID(phaseID) followed by the StartDate. Ignore the end date. I need that schedPlanPhaseID to fill in based on which text box then entered a date in on the form.
I am still very new to SQL and access so sorry if I miss something obvious.

So in an Access database I have a Customer table with a “CustomerNum” field which is a text field with the format ‘00001’ for example. This is a database that I inherited and previously had no autonumber field in the Customer table, I have since added “CustomerID”. However, all the coding in existing forms, queries, etc. is based on the CustomerNum field.
So my issue is, when adding a new Customer on a form, I’ve been trying to add the next sequential CustomerNum via vba code to a text box, but when I do so it is not saved to the Customer table. The only way I’ve been able to get the record to save is to enter the CustomerNum manually. I’ve set up a message on the form using the DMax function to inform users of the correct CustomerNum to enter, but this is less than ideal for obvious reasons.
I tried setting the CustomerNum text field using the DLookup function (=(DLookUp("[MaxOfCustomerNum]","[tblCustomer]"))+1) which does enter the correct CustomerNum in the text field on the form. But when I try to save the record, I get an error message that the CustomerNum needs to be entered into the table.
I’ve also tried using a recordset:
rec(“CustomerNum”) = me.CustomerNum
rec.Update
which appears to work, but strangely enough it restarts the autonumbering of the CustomerID field and wipes out pre-existing records (sets the newest added record to CustomerID = 1, and wipes out the previous record with CustomerID =1). Weird.
I have a form of multiple project sites where one of the fields is labelled "Project Start Date". I have another field in the form labelled "Projected Project Finish Date". Both fields are stored in a table labelled "General Project Info" (well, at least that's the source of the information for the form come from).
I could manually fill in the Proposed Project Finish Date by adding 10 days to the Project Start Date, but I would like to make it a calculated field, i.e once someone puts in the Project Start Date Access automatically calculates the Proposed Project Finished Date.
I am aware you can use a query to calculate this: New Query-->Include Project ID and Project Start Date fields, then make the third field--> Proposed Finish Date: DateAdd("d",10,[Project Start Date]). This produces a query result which has a column with all the sites, a column with the Project Start Date and a column with a date that is 10 days later. Perfect. But, how do I store those new results in my existed General Project Info table and have them appear in the form? I'm obviously a beginner and am missing something.
Thanks for any help in this matter.
Oh, I am using Access 2007.
You can use the After Update event for Project Start Date on your form to update the Project End Date control to Project Start Date + 10, but if the answer is always + 10, why store the date at all? Just use your query to show the end date.
Private Sub StartDate_AfterUpdate()
Me.EndDate = Me.StartDate + 10
End Sub
Or
SELECT StartDate, StartDate + 10 As EndDate FROM ATable
Edit
To add an After Update event, use the property sheet in form design view. Select [Event Procedure] and then click the three little dots. It will open up the code window and you can add code into the event. You will need to use the proper names for you controls, but if you type Me., intellisense will help you along with names of properties, methods and controls.
What I have here is a table with some text fields. I basically put in the name of some students into a table. I got their info from forms that teachers had sent me. When I put their names into the database, I just put the names in based on which form was at the top. Does access track the actual time that a field was put in in such a way that I could sort my text fields by that so that when I give a list of what I just did to someone else, they won't have to sort through the stack of papers to make sure all of the papers are there?
I should add that I need to track this for an individual field, not just for the record. For instance, let me take this one piece of paper I have. When I get it from an outside agency, I then put it into the database with the student's name and some info. I then need to send it to the teachers for them to sign and send back to me. I am on the second part so the record had already been created, but I want to find the date that I entered the Date_signed field basically.
In this example, you set the default value of the dtmEntered field to Now()
p.s. Same answer as HugoLemos but with a pic :)
You can use a Date/Time field with its default value = Now() to store the time each record is created, as already suggested. That approach works fine when only one user can be adding new records, which sounds like your situation.
If you wish to also store the time an existing record is changed, you can do that from a form's before update event.
This example assumes a text box named txtLast_change which is bound to a Date/Time field in the form's record source. The text box does not have to be visible to the user for this to work.
Private Sub Form_BeforeUpdate(Cancel As Integer)
Me.txtLast_change = Now()
End Sub
Create a field with a date type and set default value to Now()
As you have discovered, there isn't any way after-the-fact to know when data was entered in to your table, as it's not something that you captured in the first place. As you mentioned in one of your comments, you can determine the order in which you entered new records based on the Id, but knowing when additional data was entered would require more tracking fields.
In the future, you may want to think about a table design along these lines:
Column Name Column Description
ID Record Id
STUDENT_ID Student Id Number
STUDENT_FIRST_NAME Student First Name
STUDENT_LAST_NAME Student Last Name
... Other student info ...
DATE_ENTERED Date/Time entered
DATE_SENT Date/Time sent to teacher
DATE_SIGNED Date/Time signed by teacher
UPDATED_DATE Date/Time record last updated
UPDATED_BY User that made the last update
If it's possible, you could always edit your table and add these datestamp columns. You'd have to allow for null values, as the previous entries wouldn't have a date/time value for some of them, but it would let you track future entries.
I've got a form that returns multiple records from a table. Each of these records has a field indicating what the measurement was and the measurement's value. My form's record source pulls the appropriate ID's set of measurements and values, and then I want to write each of these measurements to different text boxes on the form.
The problem is that I'm also keeping track of the date this data was updated, and want to include only the data pulled based on the "date updated" selected at the top of the form.
When I go to pull the measurement value into a text box (with something like max(iif(Measurement="Acidity", [Value],[Null])) I get #Error all down my form. This had been working earlier today, and as I've been developing the form something changed and now it no longer works (everything but the date returned is saying #Error). I've set it to Requery when the form loads and whenever the date selected is changed.
EDIT:
This form is actually a subform of another main form. The main form has a control called MemberID which a user can use to select the Member they want information about. This is based on a query that pulls from a table the information related to that MemberID (one row per MemberID). When the form loads, the query behind the main form needs to be requeried to get the data for the selected MemberID.
Then there is this subform causing the problems. On this subform is a "Data Updated" drop down box, which lists the possible dates that the data was updated. When one chooses a particular "Data updated" in the drop down box, this chooses the latest data for all the data measures up to that date selected. This means the form's record source pulls about 10 records in my case.
Then, on this subform I try to layout these 10 records' values in different text boxes. So, in my acidity case above, I would say iif(Measurement="Acidity", [Value], Null). Because there are 10 rows returned, I will end up with 9 Nulls and 1 value, and to get that value I use the max function, so the text box's control source reads: max(iif(Measurement="Acidity",[Value],Null)).
The strange thing is this code was working this morning, until later this afternoon when I was filling in the remaining text boxes with similar code, and then it stopped working. I had also renamed the boxes from Text71 to more relevant names, but none of these are referenced in the code.
I have a table Prices:
ID -- primary key, autonumber long integer
PriceDate -- Date
Price - Currency
Quantity - Number, DECIMAL subtype
UnitPrice - Number, DECIMAL subtype (an update statement is run to keep this in synch with price and quantity, but it's just a convenience for indexing... probably it'll be replaced with an expression in my queries)
ItemNote - Text
NewStores_ID - long integer key, lookup to another table of stores
NewItems_ID - long integer key, lookup to another table of items
To enter prices for a given store on a given day, I would like to be able to select the store and date ONCE on a form, then enter the items individually in a datasheet. For reasons unexplained, this proves difficult.
I can create a subform binding everything but the store and price to a temp table TempPrices with the same structure as the original. Then I run the SQL statement
INSERT INTO Prices
(PriceDate,Price,Quantity,UnitPrice,Brand,ItemNote,NewStores_ID,NewItems_ID)
SELECT
PriceDate,Price,Quantity,Price/Quantity AS
UnitPrice,Brand,ItemNote,NewStores_ID,NewItems_ID)
FROM Temp_Prices;
This will feed all the new rows into the main table. But, when I want to set the store and date only once, I run into problems. I've tried using named parameters for date an store in the insert statement... which can cause a pop-up prompt, but I cannot bind it to a form control. I've tried binding an update statement for those fields in the temp table to a form... but it doesn't even show an option to bind a multi-row update.
How can I get this to work with a minimum of clumsy hackery? It seems like there ought to be a simple solution, and if I were using something like PHP or JDBC I'd just run an extra query.
Edit: changed storage type for Quantity and UnitPrice to Number, Decimal subtype in place of double float. Just so people won't cry about using a float in any proximity to currency. It doesn't pose a problem in my use, but there are enough people who have a knee-jerk reaction to that.
Edit 2: Form/Subform
I'm trying to structure this as a master form with a either fields for entering store name and date, or a subform for the same, then a subform mapping to the temporary table for entering pricing data. There is an action button to run the insert/update queries to dump the temp table into my main prices table and clear out the temp table. However, the problem is that I can't figure out how to get the date/store fields in the master (or subform) to bind to an insert/update value applied to all the new rows at once.
Edit 3: SQL Statements (for clarity)
INSERT INTO
PRICES(NewStores_ID,PriceDate,NewItems_ID,Brand,Price,Quantity,
UnitPrice,ItemNote)
SELECT
#MyStore_ID,#MyPriceDate,NewItems_ID,Brand,Price,Quantity,
Price/Quantity,ItemNote
FROM TempPrices;
UPDATE TempPrices SET PriceDate=#MyPriceDate,NewStores_ID=#MyStoreID;
For these queries, I cannot bind parameters for #MyStore_ID or #MyPriceDate to fields in any form. The queries don't show up as options when trying to link them to a form. I can run them and get popup boxes to input parameters, but that's not what I want.
This is the target I'm aiming at:
"I would like to be able to select the store and date ONCE on a form, then enter the items individually in a datasheet."
However, if you have a reason why you need to do it with a temp table and DML statements, then this suggestion will not be useful.
I created a Prices table with only 4 fields, then a query on that table which I used as the Record Source for a form, "fsubPrices":
SELECT p.ID, p.NewStores_ID, p.PriceDate, p.Price
FROM Prices AS p
ORDER BY p.NewStores_ID, p.PriceDate;
The form has text boxes (txtNewStores_ID, txtPriceDate, and txtPrice) bound to the similarly-named query fields. I set Enabled=Yes for txtPrice, and Enabled=No for the other two.
Then I created an unbound form "frmPrices", and in the form header added a combo box "cboStores" and a text box "txtPriceDate". The combo has Bound Column = 1 with this query for its Row Source:
SELECT l.Store_ID, l.Store_name FROM tblkupStores AS l ORDER BY l.Store_name;
Then I added fsubPrices as a subform control to the detail section of frmPrices. The tricky part is setting the Link Master/Child Fields. There is a "wizardy dialog thing", but it will only allow you to select from the available fields, and I needed to link controls on the main form with fields on the subform. To do that, I had to type what I wanted directly into the subform control's property sheet:
Link Child Fields......NewStores_ID;PriceDate
Link Master Fields.....cboStores;txtPriceDate
The result is ... choose a store and date combination in the main form ... any matching records are displayed in the subform. You can navigate to the "new record" in the subform to add records for that store/date combination. But the txtNewStores_ID and txtPriceDate controls don't show the updated values until the new record is saved.
I hope this is close to what you want. It's actually fairly quick and easy to create; not so easy to describe.
You can't really do that. You are always going to have one row being worked with at a time.
What you can do is simulate it by changing the form's Default View from "Single Form" to "Continuous Form" or perhaps "Data sheet" and making is a child(sub) form of a master form.
Then you can put the store and date on the Master form, and linking to the child form using the NewStores_ID and PriceDate fields.
