Using A Query To Add A Flag From One Table To Another
Jul 8, 2005
Hi, just so you are aware, I am totally clueless when it comes to Microsoft Access. I tried finding tutorials and help online that I could use to do this but I'm having trouble understanding what I'm supposed to do. I have two huge tables linked to each other by an ID number. One table contains multiple records with the same ID number while the other does not. There are records in the first table that don't appear in the second one, and there MAY be entries in the second table that don't appear in the first table. The second table has a flag that I would like to add to records in the first table that appear in the second table. What is the easiestt way to do this? This may be an extremely stupid question or it may be very hard, I'm not sure which, though I'm leaning toward it being a stupid question. Thank you in advance for your help.

If you've got a library database with three tables: books, clients, borrowings, would it be okay to have a field in 'books' that flags whether or not the book is currently on loan - or should that fact always be elicited from a search of the 'borrowings' table?

I have a stock-type record and a stock-item record.
I want to update a flag on the stock-type record called instock to be true if there are related stock-item records and false if there are no related records.
Does anyone know how to run a updating query that will do this?
I am fairly new to this so I'm sorry if this is a bit of a basic question.
Thank you for your help in advance.

I have a table with numerous fields including timeIn and timeOut field (these are date/time format). I need to find out how many people were clocked in during each operating hour (based upon their time in and time out). How can I run a query that will allow me to use the times in and out to 'flag' each hour that each person was on duty (a new field for each hour) so that I can run a count on the completed data for every hour?

Sorry, I tried searching the forums with no luck.
What I need to do is.
I have a table with a field called intervention day, the user then types in that field a date, pretty simple huh.
Well anyway I need the system to some how alert the user when that date comes, either through an information box or whatever.
thanks for any help,

I need a flag(indicator) for my database. This flag would be read by many different functions and depending on the value of the flag, would do one of two things.
Example: If the flag is "A", when I click a button in a form it does "C" function. If the flag is "B", then in case of the previous button it will do "D" function.
What I'm having a hard time with is where to store said flag. Mind you the flag is either one or the other ("A" or "B") for the entire database, not just a specific record(s). I thought about adding a field to my 'master' table and then use an update query to change all the values from "A" to "B" as needed, but that seemed a bit like storing redundant data.
How or where should I store this flag?

I print a certificate for each person attending my class by sending the form (StudentForm) to a report . To save time I print and sign certificates for all preregistered students then during class I enter all students that enroll the day of class. What I would like to do is flag each preprinted record so when I select the print button after all students are entered into the database all certificates except the preprinted records will be printed. Any ideas on how to flag a printed record?

I have a list of locations in a sub form where a chart has been and the last record is it's current location. I'm generating a building report which should show a list of charts on that building, but it also shows it on old locations. So in the example, it shows for building 43 and building 83. I just need it to show on 83, how to accomplish this.

Hi everyone,
I'm aware of the wizard in MS Access that creates a new table containing duplicated entries that have been entered under one column, however, my problem is slightly more complex...
A contractor of mine has recorded information from CCTV surveys of sewers (not very glamorous I know!) in a Microsoft Access database. If you can imagine - the camera can be pushed along a pipe from both ends. Sometimes, the survey is abandoned in one direction and then repeated along the same length of pipe but from the other direction. The database contains (amongst other columns) a "start manhole" reference and a "end manhole" reference.
eg:
16014
As you can see, the information contained by both entries will be the same (as they are the same length of pipe). Therefore, I was wondering how I could get MS Access to:
1. Recognise these 2 entries as duplicates
2. Create a table that hides the duplicated entry with a shorter "SectionLength" value.
Many thanks in advance.

I have a knowledge base database which lets the user search for articles containing answers to common problems and issues. Some of the users want to be able to bookmark certain useful articles. The DB is a front end/back end design so I am thinking if I have one table stored in the front end which can be used to store that particular user's favourites then that would be great. However, I a little stuck on how to implement this. Ideally, I'd like a simple checkbox option next to each article, which when ticked, would store that article ID in that user's local front end.

I'm trying to create an access database to make an inventory of my model trains.
I have a main entry form (frmTrain) where I enter all sorts of info regarding e.g. a locomotive. This info is then stored in a table (tblTrain).
In the main entry form, I've put a combo box (cmbCountries) linked to a query (qryCountries) which queries the country codes from a table (tblCountries) that has three fields:
ID (autonumber)
CountryCode (short text) (containing the country codes UK, FR, DE, ...)
FlagFile (short text) (containing the name of the flag picture, e.g. UK.png)
The flags are stored as *.png files in a folder Flags that is in the same folder as the database file. I have chosen this approach instead of putting the flag pictures in an OLE field in tblCountries because I'd like to avoid being stuck to *.bmp files (don't support transparency). I'd also like to avoid having to mention the complete file path in the field FlagFile
I created a form (frmCountries) to easily add countries to tblCountries as needed.
Now back to the main entry form. The selection made in cmbCountries is stored in the field 'Countries' in tblTrain. When a country is selected in cmbCountries, I'd like that the corresponding flag is displayed next to the combo box.
I found an example on the web where an image field was used to display the flag, let's say with the following code:
Private Sub cmbCountries_Change()
Me.ImageFieldName.Picture = Me.cmbCountries.Column(2)
End Sub
Private Sub Form_Load()
Me.ImageFieldName.Picture = Me.cmbCountries.Column(2)
End Sub
and where the combo box had as row source (not using qryCountries):
SELECT tblCountries.ID, tblCountries.CountryCode, [Application].[CurrentProject].[path] & "Flags" & [FlagFile] AS Expr1 FROM tblCountries ORDER BY tblCountries.[Code];
The problem with this example is that, if you select in frmTrain e.g. UK, the UK flag is then displayed across all records in frmTrain. So the image field is not the appropriate field to display the flag in frmTrain and I guess an unbound/bound (?) object frame should rather be used.
How to display correctly the flag picture for every individual record in frmTrain corresponding to the country chosen in cmbCountries.

Another question on how might be the best way to do things with dates ?
I have a simple database which is a fault database.
I get an email request to investigate something and I log it and give it a ticket number. If I email back , I put the comments that I sent in the email in the update field on the database.
When I create the ticket its in an open state with a date and time stamp of now()
When I close (drop down box with open and close as options) the ticket it automatically updates the time in the closed filed to Now()
What I want to do is when I updated my comments field , this sets a date value in a hidden field on the form of Now()
So then I need an expression that looks at the difference between the updated time and the now time
i.e. I update a call on 29/7/2006 at 10:00 am
Its now 30/7/2006 at 10:01
i.e 24hrs and 1 minute later
As its more than 24hrs this flags and output to a filed e.g. 1
I then total all the "1" and therefore I have a ticket count of how many calls have not been updated in 24hrs.
So Im assuming I will need an after update event on my comments field put today's date in this hidden field ,and then maybe some sort of code which is maybe on my switchboard which looks at the difference of these dates and if greater than (or equal too) 24hrs it will output a value of 1.
And If I can do this I can also have a flag if its more than 2 days , then clear the 24hr flag an increment a 24hr flag etc.
My tickets should all be closed with 24 hrs , so this is something to capture anything that is open and hasn't been updated in 24hrs
Id appreciate some guidance on the best way to do this ?
Cheers
Jimmy

I am trying to automate a membership status flag based on comparing today's date and a recorded expiry date. The expiry date control is on a sub-form. I have the following code in the OnLoad event of the master form:
Dim DateGap As Integer
While Me.CurrentRecord < Me.Recordset.RecordCount
If Not Me.NewRecord Then
DateGap = DateDiff("y", Date, Forms!PersonalMasterF!MemberSubF.Form.MemberExpire )
Else
DoCmd.GoToRecord , , acNext
[Code] .....
With debug pointing to the DateGap = statement I get the error 'Invalid use of Null'. As you can see, I've tried to trap any new records it might run into to avoid nulls in MemberExpire, and there are no null values in the MemberExpire field of the underlying table. I've also tried defining DateGap as Variant, which does not work at all.

Advanced apologies for the long question.
I have a table providing a list of all members of a local bowling club, with the following fields - MemID, MemName (table is tblMembers)
I also have two more tables providing details of matches we play in a local bowling league. The first table holds the basic match information (called tblMatches) - MatchID, Date, Opponents, ScoreFor, ScoreOpps. I've used a MatchID field as more than 1 match can be played on a single date.
The other table provides details of who played in what match and on what bowling rink and is called tblMatchDetails, with the following fields - MatchID, MemID, Rink (numeric), Result (numeric - 1 for win, 0 for loss). Each match uses different rinks, and not all rinks are used in a match, however, each rink can only be used once in a match.
We have 10 rinks, and I was looking to see if I could get a table to show me the match details along with the rinks in numerical order with who played on them in what match and their result.
For example:
Field Row: Date - Opponents - ScoreFor - ScoreAgainst - Rink 1 Player - Rink 1 Result - Rink 2 player - Rink 2 result - [and son on upto] - Rink 10 player - Rink 10 result.
Row 1: 01/01/2005 - Example BC - 4 - 3 - [blank] - [blank] - Fred - 1, etc
Row 2: 08/01/2005 - Other BC - 5 - 2 - John - 0 - [blank] - [blank], etc
I produced a query for each rink in turn which looked in tblMatchDetails and provided the following (the queries are called qryRinkOneDets - or whatever rink numebr was used):
MatchID - PlayerID with a criteria field of rink = "1" or whatever number rink it is for.
I then produced a second query providing a link of the matches (tblMatches) and the rink queries (qryRinkOneDets, etc), with the joins between the MatchID fields in tblMatches and the individual queries to provide every record from tblMatches and only those records from qryRinkOneDets where MatchID was equal.
However, the results I got only showed the match details and no info from the Rink query. If I change the join from RIGHT to LEFT, then I get the records from the Rink query but not from the Matches table. If I then do a join where only the MatchID's from the table and query are equal (an INNER join) then I get no records at all.
Can anyone figure out what I'm doing wrong?
Many thanks in advance

Hi,
I am extracting data from linked db2 table using access make table query. First I create a select query and can view the linked db2 data, but when I change to a make table query I get an error message, "invalid argument", when I run the make table query. There is no selection critera specified. Has anyone had this happen? and Do you know a solution?
Thanks for your support

Hi everybody,
Beginner here needs help !
I'm building a make-table query for which if the result is null (no record correspond to the set of criterias), a default message like "there was no activity during the period" would appear in the table (not a message box...I need the message in the output table). The best I could think of is an IIF function but it doesn't seem to work... Is there any way to do this without using VBA?
Thanks in advance !

I'm using an UPDATE query to update records in one table (tblMain) from another table (tblTemp)
Here is my SQL :
Quote:
UPDATE [tblMain]
INNER JOIN [tblTemp] ON [tblMain].[MainField1] = [tblTemp].[TempField1]
SET [tblMain].[MainField2] = [tblTemp].[TempField2];
I only want to update the records in tblMain which have a corresponding record in tblTemp (linked by MainField1 / TempField1)
If any record doesn't appear in tblTemp, I want tblMain to retain the existing value for that record.
However, it appears that in such situations, the record in tblMain has it's MainField2 value set to null / ZLS.
I've tried using LEFT JOIN and RIGHT JOIN and also tried WHERE clauses but the result is the same every time.

I have a table that is basically a survey form. The same series of options was available for 35 questions, and the table used to have a text string written for each answer. Because of all the repetitive data, I created a second table that assigned a number value to each of the nine possible options in these 35 separate fields. What happened is that, instead of the same text strings repeated over and over (and taking up real estate), now each of the 35 columns had a single number in them.
Now comes the day of reckoning and TPTB want a query with the raw data and the original text strings back in instead of the numbers. I was thinking doing something along the lines of a DLookup, but I can't seem to make that work in a query correctly. Apart from calling the same table and linking it over and over to the different fields in the original data table (see photo for how insane that is).

Dear Access Expert
I wanted to know if it is possible to change the name of the Table which is going to be created using a Make-Table Query via code (VBA).
For example if my Make-Table query currently creates a table with the name "Table1" I want to change it to name "Table2" and then change it Back to "Table1" or "Table3" etc.... depending on the users selection.

Let's say that there're 2 workers: Worker A, and Worker B, and they are fixing some engines. There's 2 different engines: Engine A, and Engine B. And these workers are fixing these engines for all day, and in the evening they have to register how many engines they've fixed.
And my job is to design Access database for them. I thought it will be very easy to do; I've created table with columns: Date, Worker, Engine, Quantity - so every day Worker A and Worker B can register, that they have repaired some amount of Engines A and Engines B.
But there's a problem that I also have to register how many Engines have arrived to the factory, and how many of them weren't repaired on time (E.g. 15 Engines A have arrived, Worker A fixed 5, Worker B fixed 5 so there's 5 engines left for tomorrow)
I've figured out that I should somehow create table IncomingEngines with columns Date, Engine, Incoming, Fixed, Undone (field Fixed should be completed automatically every day for every engine - it would be a sum of engines A and engines B fixed by worked A and worker B - so I could fill Incoming field manually)
It's easy to create this kind-of Query, but I can't add column to querry, or edit it.
