I'd like to put a WHERE clause where I confont the date in an unbound textbox with the date in the table. In vba I control the null case of the unbound textbox, but I'm not sure how to control the null value in the sql code.here is the code "strDataRiferiment" that I later insert in a concatenated SQL code. The rest of the code works, while this line doesn't. The problem are the null date records present in the table COMMESSE.What I'd like is a WHERE clause that:
- returns records with all null date values and
- returns records with not null values where these dates are < date chosen in the unbound textbox
Code:
Select Case Nz(Me.InizioDataRif.Value, "Null") 'the unbound textbox
Case "Null"
strDataRiferimento = "AND (([if is not null] COMMESSE.DataChiusura =< #" & Format(Me.FineDataRif, "mm/dd/yyyy") & "#) OR (COMMESSE.DataChiusura IS NULL)) "
Case 'etc
'etc..
end select
I tried for example:
Code:
"AND ( IFF ((COMMESSE.DataChiusura,0) IS NOT NULL,
(COMMESSE.DataChiusura,0) =< #" & Format(Me.FineDataRif, "mm/dd/yyyy") & "#) , (COMMESSE.DataChiusura) IS NULL) )) "
It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code: Private Sub cmdUpdateDates_Click() '################################### 'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time]. '################################### Dim intCounter As Integer intCounter = 0 Dim rs As ADODB.Recordset
I've got a few questions on storing dates in an MDB using SQL UPDATE...
(1) I would prefer to have empty date fields really be empty (rather than some unusal date like January 1, 0001 or whatever).
If a textbox.text equals "", what would I set the corresponding field in the database to? Some sort of Null value..?
I tried setting it equal to a DBNull value, but it didn't like that. It said, "Parameter?_10 has no default value."
(2) If a user types garbage into a text box that is supposed to hold a date, CDate(thatTextBox.text) complains loudly.
Is there a cleaner way to test the contents of the text box for valid date than to allow CDate() to attempt the conversion and then clean up the mess afterwards? Maybe something like a IsValidDate("10/11/2001") that would return a true or false.
Here is some code to put this question into context. The Null part does not work.
Dim Null as System.DBNull [...] ' Prepare Paramater [HireDate] pm = New OleDb.OleDbParameter pm.OleDbType = OleDb.OleDbType.DBDate pm.Value = iif (isdate(cdate(txtHireDate.Text),cdate(txtHireDate. Text), Null))) dbCmd.Parameters.Add(pm)
[...]
update personnel set [Lastname]=?, [Firstname]=?, [HireDate]=? where [ssno]=?
Basically I have chart in a report thats based on a query that counts the amount of entries per month between two dates inputted by the user.
It all works fine but the chart that is based on the query only shows months that have an entry.
Eg if it counts all dates between the two dates and say the only month that has an entry is July, the chart will only show July. What I want is the other months to show (Null values) as zero, so every month shows. I'm probably missing something basic but can anyone help?
[TextPriDate] is the start date [TextPriDate2] is the end date
This is the query code (QryDate) SELECT tblMain.ID1, tblMain.Dt FROM tblMain WHERE (((tblMain.Dt) Between [Forms]![frmSwitchboard]![TextPriDate] And [Forms]![frmSwitchboard]![TextPriDate2]));
This the code from the chart in the Report SELECT (Format([Dt],"MMM 'YY")) AS Expr1, Count(*) AS [Count] FROM QryDate GROUP BY (Format([Dt],"MMM 'YY")), (Year([Dt])*12+Month([Dt])-1);
My issue is that I am trying to update a date field. When I do the date field may have a date or may be a null. When I try to pass in a NULL date with no quotes, I get a syntax error. When I have single quotes in the statement and a null value is passed in, I get an invalid use of date.
Dim DENIEDDATE1 As Date If (Not IsDate(rs.Fields("DENIED_DATE"))) Then DENIEDDATE1 = Null Else DENIEDDATE1 = "'" & rs.Fields("DENIED_DATE") & "'" End If
update table1 set table1.denieddate = " & denieddate1 & " 'get Update syntax error with this statement update table1 set table1.denieddate = '" & denieddate1 & "' 'fails due to invalid use of null
how to return all values in a query when a form critieria is left blank. I have made some progress, the combo box criteria queries were fairly simple, but i'm getting stuck with my date criteria. My query doesn't return null values when I want it to.
I want it to return all records (including null values) if the form OpenFrom and OpenTo dates are blank, and just the values between the selected dates (excluding null values) if the form is completed.
Code: SELECT qryReportSelector2_Authority.*, qryReportSelector2_Authority.ApplicationDate AS ApplicationDateFilter FROM qryReportSelector2_Authority WHERE (((qryReportSelector2_Authority.ApplicationDate) Between Nz([Forms]![frmReportSelector]![OpenFromDate],DMin("[ApplicationDate]","[qryAllCases]")) And Nz([Forms]![frmReportSelector]![OpenToDate],DMax("[ApplicationDate]","[qryAllCases]"))));
I'm not sure if I am biting off more than I can chew. I have a text field in each record in my database (Inherited) The db has nearly 5,000 records. I would like to split the field into records in a seperate table. An Example of the table as is now;
Is this possible in one hit or do I need to process the records without dates first and then run another process to split those with Dates? I say dates but the field is a text field. About 15-20% of the records contain dates which are always enclosed in parenthesis.
Is there a code that will replace the empty fields by shifting the bottom fields up for access? I am planning to write a code that will delete unnecessary items in my database, however, that will cause the database to have "holes" in it.
I can't seem to figure out how to test a combo box null value.I try:
Code: If IsNull(Me.cboManufacturer) Then MsgBox ("Please select category") Else DoCmd.OpenReport "rptItemCategory", acViewPreview End If
This works if the combo box IS NOT NULL, but if null it gives me:
PHP Code:
Run-time error '3071': This expression is typed incorrectly, or it is too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables.
I then tried:
Code: If IsNull(Me.cboManufacturer.Column(0)) Then MsgBox ("Please select category") Else DoCmd.OpenReport "rptItemCategory", acViewPreview End If
This works if the combo box IS NULL but if i've made a selection, it still gives me the message box as if I've selected nothing....
Private Sub Form_Current() Dim strTime As String Dim strHour As String Dim strMinute As String If (CollectionTime.Value) = "" Then MsgBox CollectionTime
I am trying to run this code but getting a run time error 94 - null value - when it shouldn't be.I am thinking I have written the Dlookup incorrectly?
Code: Private Sub txtProductName_Click() Dim iProdType As Integer Dim ProductID As Integer iProdType = DLookup("ProductTypeID", "tblProduct", "ProductID" = Forms![frmBooking]![cboProductID].[Value]) Note ProductID in an integer
How can I diagnose this or what could the solution be?
I am using a frame on form to get report. Below is the code used to filter report.
Select Case Me.fraReportType.Value Case 1 strReportType = "Like '*'" Case 2 strReportType = " Is Null" Case 3 strReportType = " Is Not Null" End Select
The second and Third case is working fine. While the first condition is not working. This filter is on date field. There are three possibilities:
1. If we need all data 2. If we need is null data 3. If we need is not null data
How I can get the first condition using my code mentioned above.
But after the "Me.[Username]" part, I want it to also filter to only show me data that has null values on a column called "PN".Alternatively, I also need a code that instead of only showing me data that has null values, I want it to show me data that excludes the data with null values on the column called "PN".
I have a main form with multiple combo boxes that filter a subform datasheet. In my main form combo box [PR_Filter] I added a selection titled "<Blanks>". When I select "<Blanks>", I want it to filter my subform field [PR] for NULL values. If I select anything else I want it to filter on that selection. I cannot get the NULL filter to work.
Here is the code that I have (Red is the field I need the NULL values):
Private Function PurchaseFilter() Dim strFilter As String Dim bFilter As Boolean bFilter = False strFilter = ""
I'm trying to search through a table with serial card IDs, Order Numbers, and Ship Dates. I'm search through the Serial Card ID column and making my code work so that if the serial card ID exists and its ship date is between 9/30/2001 and 10/1/2011, then retrieve the associated order number and put in array. All of this works perfectly except for one tiny part : it's not returning a null for either unfound serial Card ID or serial card Ids that exist but their ship dates do not qualify. I would like to return a null value for these fields into the array as well as keep the found values in the array. The whole point of all of this is so I could count the number of rows for all the found order numbers and return a total value with that number.
VBA creating and have spent about 4 hours trying to figure out the error with my simple loop to update a few fields. As you can see from the attached picture, the "Recalc" sub simply stops updating partway through the loop.
I'm trying to add a new functionality on my search form where the user can search for records that haven't been modified(based on the field DateModified) for certain amount of time.This is what I added in my search function but it's giving me "Invalid use of Null"
If Not IsNull(Me.txtInactiveTime) Then Dim LValue As Integer LValue = DateDiff("d", Me.DateModified, Date) Select Case Me.txtInactiveTime Case "> 1 month" strWhere = strWhere & "(LValue >= " 30 ") AND " Case "> 2 months" strWhere = strWhere & "(LValue >= " 60 ") AND " End Select End If
txtInactiveTime is a combo box where the user chooses the time during which the records haven't been modified.(i.e. 1 month, 2 months etc.)
The basic idea is that I need to insert a record into a table and then return the Key field so that I can use it to populate another table. This was working just fine for a while, then it stopped and naturally I can't think of anything I did to make it not work. I get an Invalid Use of Null error at the bolded step.

I have a report in which I'm trying to hide some elements from view in case a specific value is Null. Access seems to do this automatically if the report is in print-preview-mode, but not in normal view-report-mode.
I've tried something like this, but it's not really working:
Code: private sub report_load() if nz(txtfield, 0) = 0 then txtfield.visible = false end if end sub
I have a module that creates records into a contacts table in my access database. When there is no data in the field from outlook, the data is populated as an empty string "" instead of a null value, creating problems with subsequent queries and processes. I'd like to create the data as a null value but the module keeps failing with "object is required" on the statement
It doesn't seem to like System.DBNull.Value or DBNull.Value, and when I assign the vbNullString constant instead, it gets set to "" again and not null.
I want to pass the Combobox value of one form to a textbox on another using the where condition. Using the break in VBA, the value of the combobox (in this instance "two") shows as null. the control of the combobox is [cboSubCategory] and I want it's value to pass to another form "tblCategoriesSub" (aware of the incorrect reference, as used wizard quickly - but will change if I can get it to work) to the "SubCategory" field.
I'm sending out an e-mail (see below). I want to add a cc addressee. However, sometimes the cc addressee will be blank. The e-mail works if the cc addressee field has data. It doesn't work if there isn't data. I tried an IIF statement but that didn't work. How do I can the object to work if the field is blank (null) or has data?

The following code doesn't check null condition in Scannedby field. The scannedby has text data type. The code gives me all the data where scandate=20130722 but doesn't check that scanned by can't be blank.
Code: rs.Open "select count(*) from BatchTBL2 where scandate=20130722 and scannedby <> null", cn, adOpenKeyset, adLockOptimistic j = rs.fields(0).Value
