Multiple Dcount Definitions
Aug 7, 2006
Hi Folks
I have a text box which shows the following
=DCount("[Ref number]","main","[open or clsoed] = 'open'")
This looks at a table with a primary Key called Ref Number in a table called main with a field called open or clsoed and looks for the value open only.
I need to specify another fileld, called engineer wheer I match the username =jimmy
Im struggling to add this extra field
So it wiill look , for Open and an engineer called Jimmy in a table called main that has a primary key set !
Can anyone give me some pointers on this simple question ?

Not sure if this belonged in reports or queries, so I chose general. I have looked at several DCount threads but haven't quite found my answer. I want to use Dcount in an unbound textbox in a report. It counts the number of records in another table - comparison
the first part of the statement works fine ( up to 'iss'"). When i added the between date part i'm not getting any # returned in my report. I want to addthe criteria of RecDate between the 2 dates on the open form.
Can anyone tell me where my problem lies? ( if this makes sense)
Thanks
Kevin
=DCount("[type]","comparison","[type] Like 'iss*'" And ("[comparison].[RecDate]" Between Forms!DateInputforRMAsReturned!Text0 And Forms!DateInputforRMAsReturned!Text2))

I am having an issue using DCount to validate against 3 fields within my database. I have a booking form which contains a Staff member, viewing slot, and Viewing Date which is used to book property viewings.
I want the form to check that the booking doesn't already exist when the process booking button is pressed.
I am using the following statement:
Code:
If DCount("*", "Viewing", "[Staff_ID]=" & Me.[Staff_ID] & " AND [Viewing_Period] = " & Me.Viewing_Period & "' AND Viewing_Date = '" & Me.Viewing_Date) & "'" > 0 Then
MsgBox "Cannot book, booking already exists", vbCritical
End If
I always get the error "Syntax Error (Missing Operator)".

I created a query in Query Builder which contains a DCount with multiple parameters and it runs as it should. I am trying to convert it to VBA, but my inability to put in the quotations marks correctly is frustrating me terribly.
Here is the SQL version from Query Builder:
UPDATE [Daily Status Update Table] SET [Daily Status Update Table].NumberOfChases = DCount("[ChaseOtherID5]","[Chases_View_ALL - TX_Mbr 9 Digit]","[ChaseOtherID5] = 'U - Initial Contact' AND [ChaseStatus] = 'A'"), [Daily Status Update Table].ChaseStatus = "A", [Daily Status Update Table].NewStatus = "A", [Daily Status Update Table].ChaseAssignment2 = "Unscheduled"
WHERE ((([Daily Status Update Table].ChaseOtherID5)="U - Initial Contact"));

The following code is giving me a "Run-Time error '13' Type mismatch. I have tried isolating both criteria and they seem to be fine but joined together with "AND" they error. Workdate is a Shortdate. Flightnumber and flightID are numbers. FlightID source is a cmb within my form.
Private Sub FlightID_BeforeUpdate(Cancel As Integer)
If DCount("[WorkDate]", "Main_tbl", "[WorkDate]= #" & Me.WorkDate & "#" And "[FlightNumber] =" & Me.FlightID.Column(0)) > 0 Then
Do this....
End If

I see that we can export a table, definitions only, from the master (developer) db into a client's (runtime) db.
But if there are relationships in the table, the export fails (Access 2003). How do we get around this problem?
And if the client's db is on another computer system, ie. remote from the developer, how do we import the new and amended definitions into the client's db?

Hi
I am looking for a book or poster or something that can show me all the access controls and what they do. My VB.NET version came with several posters. I have looked at many books but can not find one that enumerates and explains all of them. I would also like to get similar information for the Active X controls included with access.
Thanks

If a front-end database has links to many tables in a back-end database and the back-end is moved, is there an easy way to update all the table links in the front-end in one go, or do you have to set up all the links again one at a time?
Hoping there's a quick way...
Dave
edit: just realised the previous post asks exactly the same thing ( :o ), but that hasn't elicited a solution yet ( :( ).

As I proceed with my development I continue to rename fields. The effect of those renames is unclear to me. They seem to effect some things and not others.
What rules do I need to know about renaming the fields in my database and the effect on the forms I'm working on.

I have 192 databases that I need to redact certain information in certain columns. Generally, I'm looking for field names like name, first name, last name, address, address2, shipping address, mailing address, and phone numbers. Not sure how to get this information without going into every database and every local table inside the databases. Is there a way to get this information programmatically and just access the databases and table that I need to redact info in?

I have several tables and the default layout is one table per page. In some cases, there are a couple of fields...a waste of paper. Can this be changed?

Was wondering if someone could possibly help me with a DCount problem i'm having.
I have a form with a subform, displaying bookings that customer has made. What i want to be able to do, is when a booking is created for a customer in this subform, after the time period chosen is selected, i want a DCount to run, go to a table of regular bookings, count up how many bookings in it have the date of booking, that same as the date just put into the subform, AND the time period of booking the same as just put into the subform. There can only be 1 result at max due to its setup, and from there it should be fine, but i cannot get it to work. The field names are as follow:
Subform:
Date for Booking
Time Period
tblRegularBookings
Date For
Time Period
If this doesn't make any sense i can try and explain better.
Can anyone help me?
Thanks very much in advance

I have only been using access for about 3 weeks now, and its kicking my butt pretty hard.
Im making a query that does all kinds of math junk in it. I want to be able to find the number of occurrences of x in another column in the table.
For a better example, lets say I have a column named "SP" in the "compiled" table, the values of this column range from 1 to 5, in about 200 entries. So there is another column in the compiled table called "SPX", which has the same value range. So if I am looking at the one entry in the table, I want to take its value in the "SPX" column, and see how many times it shows up in the "SP" column.
I have been trying to get dcount to do this, but I cant seem to get it to work... Must have tried a dozen ways now.
Any help would be awesome, thank you.

My main table is called NEWcompiled, I have fields named "faction", "SPeffect", and "Launcher_ID". I am trying to use Dcount in a query to count up how many entries have a value in "faction" and "SPeffect" that are equal, and a value of "yes" in "Launcher_ID".
Currently my code looks like this:
DCount("Faction","NEWcompiled","Faction = '" & [SPEffect] & "'" And "Launcher_ID = yes")
This indeed counts how many entries have equal values for "faction" and "SPeffect", but then it seems to add that to sum of all the entries that have a yes for "Launcher_id".
Any help would be great, thank you for your time.

I've looked at numerous threads on this site and still can't get a dcount to work.
I want the database to check if there is a valid reference number entered before opening a form.
There is a table called 'staff' with a 'payroll number' field in it. This table contains all staff.
I then want the user to enter a payroll number and retrieve the corresponding record. However, if there is no match then the user has entered the number incorrectly.
I've done:
int2=dcount("[payroll number]","staff",forms!control,payroll) and then an:
if int2=0 then msgbox
end if
exit sub
However, I either now get a message when the number is correct, or it's exitting the sub every time.
Any corrections please?

What I want is for DCount to see how many times a a Box# appears in a table, if it is 0 it puts a message up that the box does not exist.
This is what I have as the code
If DCount("[tblLockbox]![LockboxNo]", "[tblLockbox]", "[tblLockbox]![LockboxNo]=" & Me.[txtGLockbox]) = 0 Then
MsgBox "Lockbox not Found! Please try again.", vbCritical
Me!txtGLockbox.SetFocus
End If
tblLockbox is the table that contains all the lockbox numbers and the names they relate too.
LockboxNo is the field that holds the Box#. I have the field set as a Text because no calculations are done with these values.
txtGLockbox: is the field on the form where they enter the Box#
The problem is I keep getting a data type mismatch in criteria expression.
I thought DCount took a count and returned a value, so it shouldn't matter what data type the field in question is.
We are using it in another area where the field in question is a number.
I hope this makes sense.

I've been back thru this DCount function, here in the forum and elsewhere. I have posted about this function before and even went back to my old post. Looks like I still need some help.
Here's the premise:
My database has a query that tracks Payments made to Students who are on the Federal Work-Study program. We have 4 categories of work: On-Campus; Off-Campus Community Service; Off-Campus Family Literacy; College Support Services.
Of all payments made to students in the year for Federal Work-Study, there are some payments in each category. On the Report, based on the query "FISAP Detail Query", programmed to show every disbursement(payment), I'd like a count of each type in the Report Footer .
I have a control on the report that I'd like to use to count the number of students paid for Community Service.
=DCount("[StudentID]","FISAP Detail Query","[Community Service Amount]>0")
and I've tried
=DCount("[StudentID]","FISAP Detail Query","[Community Service Amount]>'0'")
Count the number of students listed in the FISAP Detail Query who have a [Comunity Service Amount} greater than zero. Sum totals of disbursements for the year for each student are displayed in the Detail section of the report as a single record. So how many of these records have Commuity Service disbursements; that's what I'd like to know.
The formula returns #Error.
Anybody have any advice for fixing this? It must be some syntax or trying to use the wrong function to do the job.
Any help will be very much appreciated
Cheers!

Hello,
I am trying to count the number of records in the query result and for some reason, it's not coming up with a number. This comes up "1E+0.."
not sure what's really going on, but this started happening after i converted all my data from excel. However, records come up when i actually go run the query and not from the form.
here's my formula from the form:
=DCount("[Queue]","qryODFData","[Queue]= 'NBCT'")
I'm sure some of you have ran into these problems after data conversion.
Does anyone know what it could be?
Thank you

Ok, I admit that I know just enough about Access to be dangerous, so maybe I'm going about this the wrong way... I'm trying to set up what seemed like a relatively simple Query, but for whatever reason it's just not behaving in the way I thought it would.
We're attempting to set up a database to track sales of product, as work orders, then take that data and reorganize it through Queries for use in our payroll system.
I have the tables, queries and forms set up to enter in our work orders just fine, and there are no issues there. The problem comes when I attempt to re-query that information for use in the payroll side. Here's where I sit at the moment:
I've built a query which pulls data from the [Work Orders] table, using criteria which filters out data one employee at a time, for certain invoice dates, for only certain status codes - the ones which are payable on this payroll week. Then, I built a form, [Payroll1] and added a few fields in it which *should* pull from [Payroll1]![ProductSold] field, and count the number of instances of, say, "Digital" product, tally that number using the DCount function, and display that number on the form, for later data manipulation. It all looked good, until I actually ran the form and instead, recieved an "#Error" in my newly created field, instead of the tally of "Digital" that I expected. Am I using the function DCount wrong, or is there some other relationship that I'm not understanding here?
Thanks in advance!

I have a DCount() statement that checks to see if records (in a qryCheck) meet that condition. I have it where if DCount(…) > 0 then do something.
What I would like to be able to do is to display all records where conditional DCount() check = 0 on a certain form.
Is this at all possible? I can't seem to figure out how to do:
Show all records where DCount(...) = 0.
Thank you.

Im trying to count the number of records in a table in a certain field that match a certain criteria.
I've tried to figure out how to use Dcount with some success, but only in counting total records.
Here are two examples. The first one didnt work.
=DCount("RegisteredAt","tblGlobalReg","RegisteredAt=003 - Orland Park")
RegisteredAt is a FIeld name in the table tblGlobalReg.
RegisteredAt=003 - Orland Park is my criteria.
The second one, with out criteria did work.
=DCount("[RegisteredAt]","tblGlobalReg")
I guess my question is, how do I insert criteria?
Matt
