Bizarre Problem!
May 27, 2005
Hi All!
This to me seems absolutely bizzare! It happens in both Access 97 and Access 2003 so I know its not a version issue.
I have a Access database with a link table to a spreadsheet. I have written a query which displays data from this link table which filters out blank rows, the spreadsheet header etc and just leaves me with the data I want to import which first time I ran it was perfect and exactly what I wanted. However, it turns out that this query only works intermittently. If I run it subsequently I get a "numeric field overflow" error message. But if I go into the query design and resave it without making any changes it will then run again!!! Running it thereafter will bring back up the error message until I resave it again!!! Why is this? Any ideas anyone? I dont want to have to keep resaving it to run it.
Actually thinking about it unless I could of course resave it using code???
Regards,
Dalien51

Hi,
First time on here, so hello all!
I have a very strange request from a client who wants to do something simple that they can't because of poor database design (not mine!) . I can't think of an elegant solution so I'm wondering if anyone on here can?
They have multiple tables containing address information, for example they have one containing information about certain buildings. They can use the softcopy of the database to retrieve information about the building but for backup they now need a hardcopy.
Now part of the building information includes the alternative names for buildings (for example "City Museum" and "Art Muesum" might be different names for teh same building). The hard copy needs to have a line entry for both names (proper and alternative) and this is where the difficulty lies.
Using a simple example the table might be:
colour fruit
red apple
orange
yellow banana
The output I would need in the report is therefore:
Red (Apple)
Apple (Red)
Orange ()
Yellow (banana)
Banana (Yellow)
Now I may be being dense but I can't see how I can do this! All help very gratefully recieved :)

Greetings all,
I'll try to make this as simple as possible, but please ask for clarification if I'm unclear:
*I have one pass-through query to Informix that pulls all available class schedule information.
*I have another local query that uses information in a local table to restrict that query to a particular year and semester, chosen by the user.
*I have a function TimeConv that takes the numeric value used in the Informix db to store times (e.g., "1300") and converts it into a real time value (e.g., "1:00:00 PM").
The problem is this:
While the TimeConv function by itself always works in the local query, if I try to perform any comparisons on it, I get the error message "Invalid Use of Null". There are no null records in the restricted data. If I put the semester and year restriction directly into the pass-through query instead of the local query, the comparison operations work just fine. (But it's important that the user be able to change this without editing the SQL directly.) Only when that restriction is in the local query do I get the error message.
I've tried several ways of filtering out Null values from both queries, and it doesn't seem to make any difference. If I Nz() the fields before passing them to the TimeConv function, I instead get the error "Invalid procedure or argument call", I believe because it insists on reading "0000" as "0", which is too few digits for the function to work.
I get the same results if I try to run it through yet a third (local) query.
Relevant code and SQL below. I'm really stumped on this one. Thanks in advance for any suggestions!
Pass-through query (qryPassJoin1):
SELECT t3.days, t3.room, t2.crs_no, t3.bldg, t3.mtg_no, t1.sec_no, t3.beg_date,
t3.end_date, t3.beg_tm, t3.end_tm, t9.sex, t5.abbr_name, t1.yr, t1.sess
FROM informix.sec_rec t1, informix.crs_rec t2, informix.acad_cal_rec t7,
outer (informix.secmtg_rec t8, outer informix.mtg_rec t3), outer
informix.dept_table t6, outer informix.schd_comment_rec t4, outer
(informix.fac_rec t5, outer informix.profile_rec t9)
WHERE t1.cat="UG93" and t1.crs_no=t2.crs_no and t1.cat=t2.cat and
t1.crs_no=t8.crs_no and t1.cat=t8.cat and t1.yr=t8.yr and t1.sess=t8.sess and
t1.sec_no=t8.sec_no and t8.mtg_no=t3.mtg_no and t1.crs_no=t4.crs_no and t1.cat=t4.cat
and t1.yr=t4.yr and t1.sess=t4.sess and t1.sec_no=t4.sec_no and t1.fac_id=t5.id
and t2.crs_no NOT IN
("JFESSA", "FRESSA", "SOESSA", "JRESSA", "MAESSA", "MAORAL", "DEPO", "DEPO2", "SRESSA", "SRORAL")
and t2.dept=t6.dept and t7.prog=t2.prog and t7.sess=t1.sess and t7.yr=t1.yr
and t5.id=t9.id;
If I add this criteria, functionally equivalent to the first WHERE statement in the local query below, it all works fine:
AND t1.yr=2005 AND t1.sess="SU"
Local Query (qryCatalog):
SELECT qpj1.days, qpj1.room, qpj1.crs_no, qpj1.bldg, qpj1.mtg_no, qpj1.sec_no,
qpj1.beg_date, qpj1.end_date, qpj1.beg_tm, qpj1.end_tm, qpj1.sex,
qpj1.abbr_name, DateDiff('h',TimeConv([beg_tm]),TimeConv([end_tm])) AS NoLongLab
FROM qryPassJoin1 AS qpj1, tblSettings
WHERE (((qpj1.beg_tm)>0) AND ((CInt([yr]))=CInt([tblSettings].[catyear])) AND
((qpj1.sess)=[tblsettings].[catsess]));
The comparison criterion I would like to add here is:
AND ((DateDiff('h',TimeConv([beg_tm]),TimeConv([end_tm])))<=2)
Function TimeConv:
Public Function timeconv(numtime As Variant) As Date
timeconv = CDate(Left([numtime], (Len([numtime]) - 2)) & ":" & Right([numtime], 2))
End Function

I have a form that opened perfectly before from a click event with a standard link criteria lookup function, and...it's suddenly stopped working!
Before the form opens I get a small query box asking: Forms!support!fault ref
In other words it's asking me to enter the value it should've got from the link criteria lookup. Whatever I enter, the form then loads with the correct record.
Is there a known Access corruption issue, or does anyone have any ideas?

This is driving me crazy! I have some code that has a list of items in a listview. When I right click it shows a pop-up right click menu with a macro. Then I select an item in the list that says Rename. After ensuring a single element is selected the StartLabelEdit method is called on my list view. Then I can begin editing. Normally this works fine. However, if I first double click a list item. Then I enter my double click list view event handler and from there I open a form. Later if I close that form and then try right-clicking and selecting rename. This time after StartLabelEdit is called, the BeforeLabelEdit event is never called. The whole selected line blinks momentarily and then wherever my cursor is at that moment every item between it and the originally selected item becomes selected. If I move my mouse around the selection changes to be between the originally selected item and the one my mouse is over as it moves. It's as though I had clicked the left mouse button down but didn't let go of it and then started moving the mouse around. If I left click and release again it seems to get out of this mode, but I am still not able to ever manually invoke the StartLabelEdit method after this point. If I close the form and re-open it, it works fine. (I've tried calling refresh on the list view but this had no effect.)
Here's the really weird part. If instead of double-clicking to open a form, I right click and select a menu option to call the exact samed double click event method. Everything works fine as you would expect. Then I tried another test. I made the double click method call another method to open the form. When I did this and tried the same alternate way of opening a form, it did not work and the same original error occurred again. This weird behavior is bizarre and I have no real idea how to troubleshoot it any further.
:mad:
Has anyone ever seen or heard of something like this where StartLabelEdit goes haywire? Please help me if you can.
Thanks...

Hi all,
Been having this problem for a long time.
Everytime my function is being called, a new tuple gets inserted into Table "Stats" containing the below mentioned data.
sSQL = "SELECT * FROM Stats WHERE UserID = '"&sUserID&"'"
rs.Open sSQL,,,adCmdTable
'Save the data
rs.AddNew
rs("JaID") = lIdJa
rs("JsID") = lIdJs
rs("LanID") = lIdLan
rs("ResID") = lIdRes
rs("WsID") = lIdWs
rs("Date") = Date
rs("Time") = Time
rs("IP") = sIP
rs("UserID") = sUserID
rs.Update
Some of the weird data i got from Table "Stats"
1/25/2005 12:45:59 aaaa bbbb cccc dddd ..... row1
1/25/2005 12:46:24 aaaa bbbb cccc dddd ..... row2
1/25/2005 12:46:29 aaaa bbbb cccc dddd ..... row3
1/25/2005 12:46:35 aaaa bbbb cccc dddd ..... row4
1/25/2005 12:46:40 aaaa bbbb cccc dddd ..... row5
1/25/2005 12:46:40 aaaa bbbb cccc dddd ..... row6
1/25/2005 12:46:40 aaaa bbbb cccc dddd ..... row7
1/25/2005 12:52:51 aaaa bbbb cccc dddd ..... row8
Each time a person click on my site, one tuple will be inserted into the Table "Stats".
Time which is one of the column of the Table "Stats" is inserted into the table each time the function is called
The puzzling thing is how is it possible for the time to be the same for row 5,6 & 7.
This happens very often and i have totally no explantion for it. I tried changing the time format, date format, however i always get this.
Please advise.
Thanks a lot

I built my wife a database to use for her work that has worked fine for a good while now. Just yesterday, one of the make table queries began to act peculiar. Suddenly, whenever you try to run it it gives the following error:
"The Microsoft Jet database engine has stopped the process because you and another user are attempting to change the same data at the same time."
This is on a computer at our home so obviously no one else is trying to access it. I have checked and there are no other instances of the database running (I've even rebooted to be sure). I have checked when it was shut down and didn't see a locking file associated with the database. It is a single make table query feeding directly from another table.
As I said, it was working fine for a good while. I'm out of ideas so can anyone help????:confused:
