    Set warnings false - is this WIndows session specific, or Access session specific?

    What I mean is, when you have "Set warnings false" and then later at the end of a Module, turning it back to True, what happens if it is set to false and never set back to true? Is this going to say OFF/False for the rest of the day until you log out of windows, or should it revert to True when you close and then reopen the database?



    Thanks,

    Why don't you test it and find out? Let us know.

    I've never tested this myself. I avoid code that requires this but if I do use it I set back to True when the procedure completes and design code to set back to True in case of runtime error.

    I suspect it is a session setting.

    At the very least, I believe it will be reset when you close/reopen Access.

    That's just it - I'm having a hard time determining what is wrong in my set up. I have the lines in my module that turn off/on warnings "commented" out with a ', but the action queries inside my module, which is just a list of queries to run, are not giving warnings. I wanted to see all the warnings to make sure all queries were okay before disabling warnings again.

    Restarting Access does not revert it back. Well, to clarify, manually clicking on an action query gives a warning, but not when run with "execute" command inside the module. I just want to make sure things are working...

    Is the setting perhaps inside the VBA window and not the Access db?

    THanks,

    EDIT: I should add that this is a split database, which I have just implemented within the past hour or so. The table tehse action queries are hitting is in the back-end. So, would it not fire-off warnings for that reason? I don't seem to remember Access doing that...

    Have the been turned off already (by some other section of code or something)?
    Why not explicitly turn them on in your code before calling your action queries (there is no danger in setting it to True if it is already True)?

    If you still have issues, please post your VBA code so we can see how it is written.

    There is a clue (perhaps) where it says 'I'm using Execute '. If this is Database.Execute, this does not provide warnings, which is the whole point of it. You actually have to tell Access to provide a warning if the query fails (dbFailOnError).

    If that's not applicable, much more of the code is needed to attempt to decipher what's going on and what some of the statements really mean.

    Thank you both! I think the biggest culprit is that I recently changed from using docmd.openquery to database.execute, which as you stated, does not provide warnings. That is something I will probably temporarily change in case one of the queries is doing something unexpected, and then revert back if desired.

    Marking as Solved...

    One other thing.
    Look in Database Options...Client Settings at the confirm settings for action queries.
    Is the checkbox ticked? If not, you will never see warnings when you run action queries.

    You know me - black is black and white is white and there's nothing in between.
    So what did you really mean, as I'm sure you know that statement isn't really true (as written). Maybe the key word is "warnings", but are you applying that to when the affected record count is zero?

    EDIT: I might have to retract that statement. According to my understanding, dbfailonerror is supposed to generate a run time error if the record to be affected cannot be updated/deleted.
    Even with the option selected (to be warned) and using CurrentDb.Execute with dbfailonerror, I'm not getting warned even with the target field in the target table being locked because it's being edited. Yet M$ says
    In a Microsoft Access workspace, if you provide a syntactically correct SQL statement and have the appropriate permissions, the Execute method won't fail — even if not a single row can be modified or deleted. Therefore, always use the dbFailOnError option when using the Execute method to run an update or delete query. This option generates a run-time error and rolls back all successful changes if any of the records affected are locked and can't be updated or deleted.
    The record locking option is set to "edited record", yet no warning. So none of my testing makes any sense.
    I figured for sure, regardless of the setting you mentioned, warnings would be given if Execute failed with dbfailonerror and an attempt was made to alter a locked record, yet I can't seem to raise an error in any case. I do get the warning about someone else editing the record, but that's not what I was expecting.

    I meant EXACTLY what I said
    If you untick the 'Confirm Action Queries' option you will NEVER get a warning if you do any of these
    a) run an action query from the nav pane
    b) run an action query using DoCmd.OpenQuery
    c) run query SQL using DoCmd.RunSQL

    b) & c) are still true EVEN if you add DoCmd.SetWarnings True IMMEDIATELY before running the action query or SQL (which of course you wouldn't normally do)

    Ditto if there are no records that will be updated/appended
    The only thing I can think of to trigger a message is if the source or destination table don't exist when of course you get an error message

    In the attached example, I have unticked the Confirm Action Queries option
    The example includes my current favourite - the combined update and append query or UPEND query (AKA AppUp & Upsert)
    I've added code to run the 'UPEND' & update/append to tblOld from tblNew using each method

    P.S I ALWAYS set the record locks option to no locks but for this example also tested using locks for EDITED RECORD and ALL RECORDS - same outcome
    It would appear to indicate that the confirm checkbox takes priority over everything else

    So the MORAL of today's sermon is : ALWAYS tick the Confirm checkboxes
    I always tick all three

    thanks for the additional info! That will be helpful in making sure everything is set up optimally.
