Question

Access run update query in form

Asked by: Heather_D

Hi,

I have a form and several subforms.  I would like to setup an event that would allow an update query (already written and works) to run.  I do not want to see the results of the query, I just need the results updated to be used in another form.

Example:
Form 1 queries and returns times.
Update query updates time table with times.
Form 2 pulls data from time table and displays.

Works great with the button but I would like to have it so that a button doesn't need to be pushed.  I saw on the web where some guy took the code from the button and replaced it to point to his form and then put it in an event.  I did the same but wasn't sure what to change to have it point to the form.

Any help would be appreciated.

Heather

    When would you like the query to run? when the form opens, when the user does something else?

    docmd.setwarnings = false
     docmd.runquery "Qerey1"
    docmd.setwarnings = true

    put it in the event you want it to run from.

    by: eghtebasPosted on 2007-12-30 at 14:50:51ID: 20552388

    Or, use:

    CurrentDB.Execute "Update...."
                                      ^-- enter your SQL here

    instead of docmd.runquery "Qerey1"

    You need to decid when yyou want the query to be executed, i am assuming after the form is closed in which case you can use the docmd as specified above in the OnClose Event of the forms property page.

     

    by: eghtebasPosted on 2007-12-31 at 02:37:52ID: 20554053


    re:> Form 1 queries and returns times.

    By 'returns' do you mean it updates a text box? If so, OnChange event of the text box is where you will be putting your code so your "Update query updates time table with times" and "Form 2 pulls data from time table and displays".

    If not, the other option is using timer even of the form with timer set at 2000 (2 second). An in order for the code is fire only when it is needed, you need to add:

    Public bolDontRun As Boolean

    in the timer:

    If bolDontRun = False Then
    bolDontRun = True
    CurrentDB.Execute "Update...."
    End If

    And somewhere in your form 1, you need to set bolDontRun = False to signal timer to fire the code again.

    BTW, put following in a module, under module tab:

    Public bolDontRun As Boolean

     

    by: Heather_DPosted on 2007-12-31 at 16:01:45ID: 20557905

    The form and a subform is open.  Once the user types in the last time (time out), the subform requeries and applies the new values.  At that time, on it's refresh, I would like the update query to run.  This query will update a table that another form will be pulling values from.

    So, I guess I would like the update query to run when the user clicks on the subform and after the subform is updated.

    I hope this helps....I give the above suggestions a try.

    Happy New Year to everyone.  I appreciate the help!

    Heather

     

    by: pierre_rouxPosted on 2008-01-01 at 00:07:26ID: 20559067

    In that case use the onAfterUpdate Event for your subform, then requery the main form to see the latest resultset.  

     

    by: eghtebasPosted on 2008-01-01 at 12:33:14ID: 20561323

    Going over parts of your last post:

    re:> Once the user types in the last time (time out), the subform requeries and applies the new values.

    The key part her is "subform requeries". The event I suspect you need to try is the On Current event of the subform. And, if the user enters the date to the subform:

    CurrentDB.Execute "Update...."    'in On Current event of the subform

    It will be nice for you post the SQL of your query to see if it needs update using a value from the form or the subform.

    Happy New Year to you as well.

    Here is the sql scripts...by the way, I tried the above code in various event locations and nothing worked.  Not sure if I was using the correct info.  For the following:

    docmd.setwarnings = false
     docmd.runquery "Qerey1" (I used the name of the query "Update TimeUsed Query"
    docmd.setwarnings = true

    Maybe I should have used the control name...not sure if the query would have one.

    Here are the queries:

    Time Used: Main Form
    SELECT ParentInfo_TB.ParentID, TimeUsed_TB.ParentID, ParentInfo_TB.ParentID, ParentInfo_TB.Parent_LastName, ParentInfo_TB.Parent_LastName, TimeUsed_TB.Time_In, TimeUsed_TB.Time_Out, ([Minutes]\60 & Format([Minutes] Mod 60,"\:00")) AS Total, TimeSerial(Hour([Total]),(CInt(Minute([Total])/15)*15),0) AS RoundTotal, DateDiff("n",[Time_In],IIf([Time_Out]<[Time_In],1,0)+[Time_Out]) AS Minutes, Format(([Minutes]\60)+(CInt(([Minutes]-(60*([Minutes]\60)))/15)*15/60),"Fixed") AS TimeFRMT, *
    FROM ParentInfo_TB INNER JOIN TimeUsed_TB ON ParentInfo_TB.ParentID = TimeUsed_TB.ParentID
    ORDER BY TimeUsed_TB.ParentID;


    Time Query: Subform
    SELECT [Time Query].TimeUsed_TB.ParentID, [Time Query].Parent_LastName, [Time Query].TimeFRMT, Payment_tbl.PaidTotal_Hours, [TotalHours_Left]-[TimeFRMT] AS [Left], Payment_tbl.TotalHours_Left
    FROM [Time Query] INNER JOIN Payment_tbl ON [Time Query].ParentInfo_TB.ParentID = Payment_tbl.ParentID;

    Update Query (Background Query):
    UPDATE (ParentInfo_TB INNER JOIN [Used Time Query] ON ParentInfo_TB.ParentID = [Used Time Query].ParentID) INNER JOIN Payment_tbl ON ParentInfo_TB.ParentID = Payment_tbl.ParentID SET Payment_tbl.TotalHours_Left = [Left];

    Thanks again,

    Heather

    In the events you try, have

    MsgBox "subform events fired"   'using the event name as it applies

    This is to make sure, in requerying of the subform's on current event it fires. If it doesn't fire (which it should in requeryin it) we have to see what the problem is.

    After we located the event, use

    'docmd.setwarnings = false
     docmd.runquery "Qerey1" (I used the name of the query "Update TimeUsed Query"
    'docmd.setwarnings = true

    to see if there is some kind of error with the running of the query. We can remove the single qoutes later.

    Hi Mike,

    I did the above suggestion and received an error in the code.  It stopped at the docmd.runquery, highlighting the runquery word.  I noticed that when I typed in the code earlier, it did not show up as an option.

    Thanks,

    Heather

     

    by: Heather_DPosted on 2008-01-02 at 11:48:11ID: 20567191

    Hi Mike,

    I got the message box to pop up and fire the query.  I had to replace the runquery with the "Update query statement."  That worked!! BUT, I it is firing the update query when the form is open.  I tried to move the update query around to something other than CURRENT like on click, or after update, etc; but it doesn't seem to be firing the update query when clicked.

    Any suggestions as to where I can put the query and why it is on only working with the on Current event?

    Thanks,

    Heather

    Hi Heather,

    I guess we are getting closer to solve it. You probably remeber my post asking you, in a module, to include:

    Public bolDontRun As Boolean

    The value of this will set to true when the user enter a value that running the update query becomes necessary. Say, when user enters a time value in a text box, then in that text box after update enter:

    bolDontRun = True

    Now, chnage your code in the on current event to:

    If bolDontRun = True Then
       CurrentDB.Execute "Update...."
       bolDontRun = False
    End IF

    This way, it updates only once. When a value is entered into a specific text box.

    Mike

    Have a great day!

    I would love  your help with the query issues.  Is there a way I can post it question so that you can get the points? I can post the question, but I am not sure if you can find it.

    Thanks,
