Mapping? Change Query? VBA?
Jan 18, 2008
Issue: We have software that maps some of our "custom" grades that we use locally to the state-specified grades when we submit.
Ex: Grades PA and PP map to report to the state as PK. The data stays in our software as PA and PP however as it is needed that way.
I'm trying to run queries comparing our data with what is at the state to head off mismatches and want to find a way to NOT have these grades show a false mismatch. The field for flagging as mismatch is for example
GX = iif ([schoolgrade] not like [stategrade], "GRD", null)
I tried doing a compound iif statement in my comparison query field but got stalled there as there are 6 or 7 grades that map, one with 3 that maps to one state grade.
What would be the best way to alleviate these? I know I can do a change query, but I'm assuming that can only be done one at a time, and I would have to import the data. Doing find and replace is too manual, and the data is updated daily so I would want something automated.
At this point I'm thinking of creating a bunch of change queries and automating the running of them but that seems like the long way to do it...

I have a database consisting of one table with 5 columns, called Name, Zip Code, Model, Serial #, and Reference #
I made a form with 5 text boxes (generically named Field 1 through 5), and then I built a query. I put all five of the table's fields in the query. In the criteria fields of those five columns, I have
Criteria: Like "*" & [Forms]![Search_form]![Field1] & "*"
Criteria: Like "*" & [Forms]![Search_form]![Field2] & "*"
Criteria: Like "*" & [Forms]![Search_form]![Field3] & "*"
Criteria: Like "*" & [Forms]![Search_form]![Field4] & "*"
Criteria: Like "*" & [Forms]![Search_form]![Field5] & "*"
However, here in lies the problem:
Some of the records don't have a reference field included, and others don't have serial numbers, and etc. Basically, some records have blank fields.
So to find all of "John"s records, we would put John in Field1, and then run the query.
The first criteria is now looking for *John*, which is correct (it might find Jack John, Johnny, John John, or anything else with j o h n in it).
The rest of the criteria are now looking for **.
However, what about the records with blank fields?
John ; _____ ; SDMS71 ; 1231234 ; REF9001 will NOT make it into the query, because that blank field for some reason doesn't meet the ** wildcard!
how can I accomodate this "blank field" problem? I want those records with blank fields to still be included in the query, because they still belong to "John", and that's what i wanted to search for! :(

Hi
I've built a macro that runs through about 12 queries one after the other, which I run every day. They basically bring in data from a data warehouse held on a Pervasive server through an ODBC link, then perform calculations based on other criteria in tables held within the access database. Up until about 10 days ago, the whole thing took about an hour to run. Then all of a sudden, this changed and it now takes around 5 hours. I haven't made any changes to the macro or any of the queries which it runs. I was wondering if anyone has any ideas what might have caused this (as it's now almost unusable). I've compacted the database to remove bloat, added more RAM, moved the Access DB onto my C drive instead of the server, stopped my antivirus program from looking at either my access DB or the datawarehouse where the data comes from, pestered the network guy to find out if they've changed anything to do with the server (he says no). Any ideas for other things to try would be great, as I'm on the verge of throwing my PC out of the window in case that helps!
Many Thanks
Andrew

Ok, been puzzled by this one.
I have a form with a subform in it. The subform is based on a query. It shows all my active staff. On the form i have a button that (atleast i would like that it does that) when clicked it sets the field "selected" on true on the subform.
The code behind the button works just fine, but i always get an error stating, can't change data, database or object is read only. Funny thing is, when i click on the checkbox "selected" in the subform behind each staff member, i can set it to true. Why does it not work? I tried it with selecting the query itself (qerWerknemersActief instead of tblWerknemers) and also not working. Here's the code, hope someone has a clue. Oh, in each form everything is set on yes except adding records, so it's not that change records is set to no.
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim strSQL As Variant
strSQL = "SELECT tblWerknemers.Id, tblWerknemers.Werknemer, tblWerknemers.Selectie, tblWerknemers.Actief " & _
"FROM tblWerknemers " & _
"WHERE (((tblWerknemers.Actief)= True));"
Set db = CurrentDb
Set rs = db.OpenRecordset(strSQL, dbOpenForwardOnly)
Do Until rs.EOF
rs!Selectie = True
rs.MoveNext
Loop
rs.Close
Set rs = Nothing
Set db = Nothing
Call Form_frmBeheerDeelnemers.Requery

I have the following query, named "Query9" (Right, I didn't assign it a name when I first created it). Its SQL is:
SELECT LA.DL_ID, LA.UPB, LA.[FMLNo]
FROM LindActivity AS LA
UNION ALL SELECT [Q].[Deal ID],[Q].[CSUPB],[Q].[CBIID]
FROM [qry_DSRCB] as Q;
Both LindActivity and qry_DSCRB are queries, neither of which makes any reference to "Query9".
This query runs fine. However, when I change its name to PCBStack, it can't find Query9.FMLNo. If I change its name back to "Query9", it runs fine again.
Also, if I copy the SQL from Query9 and create a new query, PCBStack, and paste the SQL into it, it runs fine.
Anyone have any idea what is going on? I am using Office 2003 with Windows XP

I had been using some SQL in Access with many IIf statements. I understand the equivalent in SQL is CASE, WHEN, END.
However, I'm really stuck with the following:
oh..ISNULL used to be Nz as well
IIf(ISNULL(ZI.InvoicesRaised,0)=0,0,IIf(IIf(ISNULL (ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)>0,30,(ISNULL(ZA.TotalDebt,0)*30)/ISNULL(ZI.InvoicesRaised,0)),0)>0,IIf(ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)>0,30,(ISNULL(ZA.TotalDebt,0)*30)/ISNULL(ZI.InvoicesRaised,0)),0),0))
+IIf(ISNULL(ZIMinus1.InvoicesRaised,0)=0,0,IIf(IIf (ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0))*30)/ISNULL(ZIMinus1.InvoicesRaised,0))),0)>0,IIf(ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0))*30)/ISNULL(ZIMinus1.InvoicesRaised,0))),0),0))
+IIf(ISNULL(ZIMinus2.InvoicesRaised,0)=0,0,IIf(IIf (ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0))*30)/(ISNULL(ZIMinus2.InvoicesRaised,0)))),0)>0,IIf(ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0))*30)/(ISNULL(ZIMinus2.InvoicesRaised,0)))),0),0))
+IIf(ISNULL(ZIMinus3.InvoicesRaised,0)=0,0,IIf(IIf (ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)-ISNULL(ZIMinus3.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0))*30)/(ISNULL(ZIMinus3.InvoicesRaised,0)))),0)>0,IIf(ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)-ISNULL(ZIMinus3.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0))*30)/(ISNULL(ZIMinus3.InvoicesRaised,0)))),0),0))
+IIf(ISNULL(ZIMinus4.InvoicesRaised,0)=0,0,IIf(IIf (ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)-ISNULL(ZIMinus3.InvoicesRaised,0)-ISNULL(ZIMinus4.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)-ISNULL(ZIMinus3.InvoicesRaised,0))*30)/(ISNULL(ZIMinus4.InvoicesRaised,0)))),0)>0,IIf(ISNULL(ZA.TotalDebt,0)<>0,IIf(ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)-ISNULL(ZIMinus3.InvoicesRaised,0)-ISNULL(ZIMinus4.InvoicesRaised,0)>0,30,(((ISNULL(ZA.TotalDebt,0)-ISNULL(ZI.InvoicesRaised,0)-ISNULL(ZIMinus1.InvoicesRaised,0)-ISNULL(ZIMinus2.InvoicesRaised,0)-ISNULL(ZIMinus3.InvoicesRaised,0))*30)/(ISNULL(ZIMinus4.InvoicesRaised,0)))),0),0)) AS DD
Do I have to put in some seriously heavyily nested CASE statements or are there some other ways round this?
