Datediff Parameter Criteria
Dec 12, 2007
Problem:
I have a datediff function as a field in a query:
DateDiff("d",[ClientHistory].[Date],Now())
When I put in the criteria: >30
I get two results based on the datediff values equal to 37 and 110 for the two records.
Now problem: when I use >[Enter value] for the criteria and enter 30 at the prompt. I only get the record with 37, even though 110 is higher...
It seems very inconsistent based on the values I enter at the parameter. Have you ever experienced this or know what might be going on? All works fine if I hard enter the number in the criteria of the query, but not when I use a parameter.
I'm using Access 2000 on Vista and XP - both systems have the problem

Hi:
I need to translate this VBA DateDiff into SAS and am not familiar with the "1>9,9"
I know "/" means divide but have never seen ""
Thanks for your help.

*Mth_1st_PNC: IIf(IsNull(DateDiff("d",DateDiff("d",[gest_age_days],[infantdob]),[calc_begin_pnc])/301),9, IIf(DateDiff("d",DateDiff("d",[gest_age_days],[infantdob]),[calc_begin_pnc])/301>9,9, IIf(DateDiff("d",DateDiff("d",[gest_age_days],[infantdob]),[calc_begin_pnc])/301<1,1,
DateDiff("d",DateDiff("d",[gest_age_days],[infantdob]),[calc_begin_pnc])/301)));

I've successfully created a DateDiff calculation that is generated with a d:h:nn format. Now the question:
How can i select or identify specific values, such as <= 2 days using those outcomes generated by the expression? Is it possible?
Example: a value is generated as 3:14:35. I would want to indicate this more than two days by putting a "N" in a separate column.
How is this done?

Hi All,
I have a parameter-query and when you execute it and 'fill in' the parameter it takes a very very long time when the results are displayed on the screen.
Now, that seems normal if you have a very large table, but when I enter the parameter in the criteriafield manually it displays the results immediately. Very strange. I have indexed the field so that cannot be the problem.
Does someone know what I do wrong?

In MS Access 97 I have a basic query based on a single table. When I use "Between [Start Date] and [End Date]" as the criteria in a date field it returns incorrect records.
It works correctly on date fields that are not calculated but not on the date field that is calculated. If I type in the actual dates in the criteria (instead of the prompts) it returns the correct records.
Is there a solution to this behaviour? I need the users to be able to input the dates.
Thanks.
P.S. I have tried using the base query as a subquery but I still have the same issue in the second query based on the subquery.

It is possible to create a parameter query in Access that will search for records that match the parameter entered by the user AND contain all other records that have that value plus other text.
For instance you may want Access to return all records that begin with the letter Q.
To do this you need to enter the following expression into the criteria row:
Like [Find records beginning with:] & "*" Or Is Null
The user can enter a Q and the criteria concatenates the wildcard character * to this parameter value, to find all text strings that begin with a Q.
By also using Or Is Null in the criteria the user can enter a blank value into the parameter query to return all records, even if this field is blank.
But how do I search if i want all the records with John anywhere in the field???

Hello Everybody,
I have an append query that contains a parameter [PTIdent] under the field named PTID. I would like to be able to set the parameter through VBA from a control on a form eg Form!PTID
I use the following code as normal
Private Sub Command19_Click()
On Error GoTo Err_Command19_Click
Dim stDocName As String
stDocName = "apNewPres"
DoCmd.OpenQuery stDocName, acNormal, acEdit
Exit_Command19_Click:
Exit Sub
Err_Command19_Click:
MsgBox Err.Description
Resume Exit_Command19_Click
End Sub
Is there a way within this code to do this? I realise I could set the form criteria within the query itself. However I wanted to be able to use this query from multiple forms.
Thanks for any help

I have a table that has three columns: Nationality, Gender, and Date. First I had the problem of grouping the Nationality column by Gender. That i resolved by creating a crosstab query. Now, I want to put a criteria on Date field so that when the query is run it will ask for the date input and will only show the Nationality and Gender result for specific dates. But when I write something in Criteria field it shows an error saying: "The Microsoft Access database engine does not recognize "[Registration Date]" as a valid field name or expression"..

I have one form which have two multiselect listboxes. They work, but every time when I choose id_organizacija from listbox popup enter parameter value comes up.
I am already tried to put id_organizacija in [ ] but that didnt solve problem.
Code:
Set ctl = Me.lstEmployees
For Each varItem In ctl.ItemsSelected
strWhere = strWhere & ctl.ItemData(varItem) & ","
Next varItem
Set ctl = Me.lstOrganizacija
[Code] ....

I'm trying to create an query that has two separate expression in it and a date selection criteria. The first expression is,
Expr1: DateDiff("s", [Arrival Time 1],[Departure Time 1])/3600
and the second is,
Expr2: IIf([Expr1]>[Hours Per Day],[Expr1]-[Hours Per Day]
When I run this query it asks me for the date (which is fine) but then it also pops up a box asking for "Expr1". How can I get "Expr2" to use the value returned from "Expr1"?

I had an issue with writing LIKE statements in query criteria yesterday [URL]....
The answer they gave worked perfectly when I only used a single table in the query. But as soon as I did an INNER JOIN with two other tables, now I get parameter value prompts when I open frmSearch, and instead of seeing ALL my records when the controls are left null, I get only the first record in the table.
Here's the SQL of the query, can you point out what I messed up? NOTE that this SQL was 'written' by Access.. as I used the Query builder to set all the 'Like or Is Null' statements, then clicked SQL and sorta formatted the code so I can see what I'm looking at (instead of superthick wall-o-code):
Code:
SELECT tblPeople.name, tblPeople.num
FROM (tblPeople INNER JOIN tblAddresses ON tblPeople.name = tblAddresses.name)
INNER JOIN tblPets ON tblPeople.name = tblPets.name
[code]....
Basically, this is a searchable database of participants in a pet-adoption program, along with the participants' pets history and address history (hence the linked tables as opposed to additional columns in one single table for pets and addresses... there are more than one in some cases). The frmSearch allows a person to run quick searches based upon ANY item in the database, such as name, pets, addresses, pet age, pet type, county of residence, etc. I need to be able to pick ANY field on frmSearch and type a value, and have the qrySearch return records for ANY record's related column wherein any part of it matches what I typed.
The statements as written worked PERFECTLY right up until I added the INNER JOIN. Now I get a set of parameter value prompts for every field on frmSearch that's referenced in the SQL for EACH table I linked to tblPeople, and if I leave everything null and click Search, I want to see EVERY person, but I'm only seeing the very FIRST person in tblPeople.

I've created a farm database, with a form (frmSearch) that will allow user to filter data. The form comprises of combo box and list box etc... for the user to input their own criteria. The subform below has a datasource. The data source is based on a query (qContractionSearch) which is basically a parameter query with 3 tables. The problem is, however, that it won't work with 3 tables... but will work if data source comprises just one table.
See the farm database attachment...and go to frmSearch...then go to Contraction tab. (The Cattle tab filter works fine-it only has a single-table datasource).i have a requery macro which runs whenever the user clicks 'search'.

I have a report that is fed by a parameter query. When a command button (Command23) is clicked a parameter box opens and the user enters a subsystem number. A report for that subsystem then opens.
I want to open the report with VBA and show a message if the user has failed to enter a subsystem number in the parameter box and just clicked OK.
The problem is I don't know how to refer to the parameter box and detect if it has been left empty before clicking OK. I first tried to use IsNull in an If statement with Command23.Value, but now realize it is the value in the parameter box I am after, not the "value" of Command23.
How can I change my code to detect if the parameter box has not been filled out?
Private Sub Command23_Click()
If IsNull(Command23.Value) Then
MsgBox "You did not enter a Subsystem", vbOKOnly, "No Criteria Entered"
Else
DoCmd.OpenReport "rptTESTInfoBySubsystem", acViewReport
End If
End Sub

My form-based search mechanism uses controls to set the parameters for the query data source.
I have one field call quantity in stock. I could you a Between and And method to allow the end user to input the stock quantity they want.
HOWEVER, i would love it for the user to first select the Comparison Operator (e.g. > , <, >=, <=) from a combo box and then in an adjacent text box, enter the quantity.
The expression i entered in the query goes something like this.... Forms![frmSearch]![cboRange] & [Forms]![frmSearch]![txtQuantity]
When i try and run this, i get the message "THe expression is too complex to be evaluated".

I am trying to create a parameter query to return dates that have 2 years remaining.
For example I have dates for when mortgages expire, and I want to recognise the dates that have two years remaining using a parameter query but I can't figure out if I use DateAdd or DateDiff.

Is there a way in a query to write a datediff that looks at all the possibilities month, day, year? I have 10 different fields that I need to do a date diff on. I would like to have the fields checked in one place rather than 10 day checks then 10 month checks and 10 year checks. I don't need to use the data any where but I need it to let me know if there is a difference between a calculated date and a date that was input by a user. If there is then I know the user input the wrong date, and it shows as an error.
Thanks

Hi,
I am trying to calculate the number of days between 'today' and a 'date of birth' field. In the field properties Default Value I am using =(DateDiff('y',Date(),[dob]) where Date() gives today's date and [dob] is my 'date of birth' field. However, this is not working. I get an error "(The database engine does not recognize either the field 'dob' in a validation expression, or the default value in the table 'Table1')"
I have set the data type for both fields to 'Date/Time'. What am I doing wrong? Is there any alternate method?
Also, how can I calculate height in feet & inches (5'6" or 5.6 or 5-6) from a given height in meters?
Thanks

hello all,
i have a very simple databse with two table in it,, both table share a lot of common information, including a primary key called jobcard number,, i want to know if there is a simple query i can run that will find any differences in the start date fields that are found in both tables
any help would be much appreciated
cheers

Look at DateDiff function in the help for the time differences.
Thus for example in a new column in your query you can type:
DifferenceInDays: DateDiff("d",[Table 1 Name].[DateField Name], [Table 2 Name].[DateField Name])
--------------------------------------------------------------------
thank you DrSnuggles,
could you explain in idiot proof instructions?
do i enter the diffdate code in the criteria row of the select query? also, what do i need in the field and table rows? is it the table and filed i'm comparing the data against?
once again
many thanks

I have a call tracker database.
What I'm trying to create a query to view all my calls' time average (opened date and resolved date). Basically, how long it took to fix a call or problem... whatever...
I tried with datediff(), but had problems getting the Total Avg.
I would need the query to look like this...
Total Calls | Avg Call Time
100 | 5.33 (min.sec)
Thank you
Lucas
