Hi.
I have a db with a numeric field called Eur_2.
This field is populated with data imported from an excel file.
When the Eur_2 excel field contain Null, in the correspondent Access Field the value inserted is 0 (zero).
I have necessity to put in the Access field Null value.
The VBA code that I use for import is:
Eur_2 = XL.Application.Cells(indriga, indcolonna + 10)
If Eur_2 = 0 Or _
Eur_2 = Empty Then
Eur_2 = Null
End If
but when i open the Access table, the value inserted is 0 (zero).
There's something to do for change 0 (zero) to Null?
Hi Guys, i have a problem in converting NULL to 0 , i wrote a query which gave me a Null value, But i would like to know if there is any way i can change the NUll value to 0.
ex SELECT Sum(xxxx) AS yyyy FROM zzzzz WHERE******=#####;
I would like to convert zero if enter into null value during the data entry phase in a form. This means that zero values will be stored as null values. Is there a way? I am not able to do it in the input mask somehow.
Simple query, but I need to roll the results up with others and a null return is hurting me. I have been chasing my tail around with the nz(), input masks, IIF statements, only to prove my ignorance and possible insanity for expecting different results.
Here we go:
SELECT Count([LDB LOG].DSTHTL) AS ["tot120"] FROM [LDB LOG] WHERE ((([LDB LOG].[LDB Rcvd]) Between Now()-120 And #1/1/2008#)) GROUP BY [LDB LOG].[T-7 Date] HAVING ((([LDB LOG].[T-7 Date]) Is Null));
This is being used to count open items into age buckets, the above is the greater than 120 days (discounting anything prior to 2008). If the T-7 Date is null the item is open. What is happening is that no records are being selected, resulting in the null value back.
Any help would be greatly appreciated as I have spent an unrealistic amount of time on this.
I have a query which returns, among other things, a number of boolean fields. In some cases, there will be a genuine True or False value in each of these fields; in others, it can and should be Null (e.g. as a result of a 'failed' LEFT JOIN of some description, where there is no associated record in the joined table which fulfills the criteria)
So something like this :
Code: SELECT [tblTable2].[fldBooleanField].... FROM [tblTable1] LEFT JOIN [tblTable2] ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, I will be writing the result of the query to a text file and here's the problem. I want to show a numeric value for a genuine True / False (i.e. -1 and 0 respectively using the standard boolean conversions in Access) and a blank for any Null values.
So I tried this :
Code: SELECT CInt([tblTable2].[fldBooleanField]) AS fldBooleanField.... FROM [tblTable1] LEFT JOIN [tblTable2] ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, currently when I look at the exported recordset in Notepad, I am getting 0's for both False and Null values (and -1 for True)
How I can adapt my query to keep Nulls...null? And convert the genuinely present boolean values to integer form?
Only thing I can think of is to use (untested) :
Code: IIf([tblTable2].[fldBooleanField] Is Null, Null, CInt([tblTable2].[fldBooleanField]))
But there's a number of boolean fields in there, all requiring the same treatment.
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
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
I am having problems with setting up a set of combo boxes.
What I am trying to do is if combo Productline is empty then in combo PartNumber would show all products but if combo Productline has a value selected then in the combo partnumber would only be able to select the partnumbers in that productline.
Hi, I have some problem with assigmnet with date and string variable. what i wana do is get data from Forms textboxes into variable and then by insert query send to history table.
the problem occurs when there is blank textbox its says invalid use of null.
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
We have both Access 2003 and Access 97 users on our network and i have a database that is written in 97. But lately we've been getting unrecognized format when we open it. So my guess is someone out there is opening it in 2003 and converting it. Is there a way to tell the database to ONLY run on 97 and DO NOT convert to a different version?
I am running an Access Database for a large uk companys call centre.. I use many diffrent systems which allow me to show our centres productivity...
I have hit a wall
When i first developed the DB i used the time formatting hh:mm:ss but later down the line i found if you *the time by 86400 it converts the hh:mm:ss into a workable seconds format....
One of my old extracts that i feedinto the DB are in the old format therefor i do this calculation within an access query which *the time by 86400
however i have found an probelm.. if the time is over 24hrs it seems to double the time there or there abouts in seeconds
example
01/01/1900 01:42:00 which is basically 25 hrs should be around 92520 seconds
when is do this calculation in an access query it is coming out 178920 all the other times are correct so this rules out how i link 2 querys ....
Hi, hope someone here has experience with this issue.
Our system was recently converted to much tighter secured network environment and moved to Office 2003 (still Windows XP).
Within the next couple of weeks we expect to split/secure our new db for shared use across a network (approx. 6-8 users at any one time).
I want to keep the db in 2000 as long as possible because I'm doing lots of the work at home and that's what I have. After deployment there will be lots more changes but in managed releases. (sounds official, eh?...)
Does anyone know of any risks I'm running by keeping it in 2000 within Access2003?
When I load a spreadsheet I can't add an index because it is a linked table, so I want to save it in MDB format so that I can add an index and then export it to SQL. However, when I save the file as an MDB file the data is all still linked as a spreadsheet and I still can't add an index. (I would add the index at the last step in SQL, but Pervasive SQL is very temperamental.)
Basically I just want to export an Excel spreadsheet into SQL and add an index.
I have a query in which I am splitting a long integer into Month, Day, Year and then putting it back together using Date Serial in another query. When I originally set this up, the date was coming through as 5 numbers. Now it is coming through as six. However, Access will error out if I try to set it as a date.
So, how can I redo the fields below to get 2 digits for the month instead of one. The date now comes through as 041706
CInt(Mid([Field1],1,2)) AS iMo, CInt(Mid([Field1],2,2)) AS iDay, CInt(Mid([Field1],4,2)) AS iYear
Looked through DateSerial but possibly not the way to go. I have a text field, "Month", with the dates in this format: Jan-06, Feb-06. What do I use to convert these to date format? 1/1/06, 2/1/06.
Hi all,I'v been at this for awhile nowI did a search and tried out some of the examples but for some reason they didnt work.Heres the format i have it in. D| O | B04 | 30 |1967 all in a text fieldI need to convert it into 4/30/1967I tried creating a new field called DOB and setting it to date/time and then using a concate query but it said it could not convert it.UPDATE Table1 SET Table1.DOB = [D] & "'/" & [O] & "/" & [B];UPDATE Table1 SET Table1.DOB = "#" & [D] & "'/" & [O] & "/" & [B] & "#";Please helpTake care
My query is... SELECT tblExtensions.Extensions AS 'PIN', tblExtensions.Budget AS 'LIMIT',
tblExtensions.Extension is text tblExtensions.Budget is number
I would like to convert the tblExtensions.Budget to a text/character filed for further manipulation. In SQL it all works, how do I change this in MS Access?
