When I started building forms to fill my junction tables, the example that I looked at based them all off of queries. That's what I've done for the most part. However, this latest subform that I've made and embedded into a main form is based off of a table. Will that cause problems for me down the road? I'm not so far with it that I can't redo it off of a query, I just don't want to!
View RepliesI have a main screen that has a tabbed form in it. Each of those tabs has a sub-form in it that displays information and allows some information to be updated.
In one tab I have a query based sub-form that returns information related to the project. This information cannot be manipulated or changed as it comes out of a company managed database. I would like the analysts to be able to add more granular information to a new table by inputting information in a dropdown field for one of the new table fields, but utilizing two of the existing sub-forms fields as identifiers in the new table.
I have a form that users can input data into and based on that data it runs a query and generates a report. These reports can be different based on user entered data on the form. My issue is within the report I would like to sum certain fields. The problem with trying to sum theses fields is that they show up on each row so I have hidden duplicates but when trying to sum the field it still trys to count the hidden duplicates thus giving a value that is of no use.
I have tried many methods to sum but one of the problems I continue to run into when I create a text box and build an equation and reference the field I would like to sum is when the report runs it is asking for a value to be entered for the field I am attempting to sum. I shouldn't need to enter a value as I am trying to obtain the value.
I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.
I have a keys table and a keysctivity table. I need keys to not be available if they are currently signed out (return_date is null) or if they have been marked as lost (lost_key = true)
This is my activity table. URL....If for example signin_id 1 was not returned or was lost, key_id 1 should no longer be available. Is this something that can be done?This is the access file I am working on: URL....
create two new tables "lostKeys" "unreturned_keys" and have records moved to their respective tables based on whether they are indicated to be lost or currently not returned.
i'm creating a database which holds all animals. i'm trying to make the parents selectable in a subform based on the same table as the main form - this doesn't work for whatever reason ("table is already opened exclusively by another user,..."). it can't just be one field or a query, it needs to be a subform because besides name and eartag i also want to display a small picture of the parent and only the filename is being stored.
i'd really like it to be selectable records in a continuous subform, so the risk of selecting a wrong id is minimized. is there a way around this not being able to use the same table for a subform?
I would like the subform in the lower left corner to be blank when
I open the program. It is populated from my tblClients table.
How it works in general is you select "x" number of items from the
list box...hit the search button and the results go through a query
and then show up in the subform.
everything works ok but, like I stated I would like the subform to
be blank when the program is first started up.
It seems to be retaining information from the last start up in the
subform box.
Thanks for your help...it's coming along great so far...
see attached doc...
Because my tables were already large I split them up by environment to speed up data maintenence and retrieval. Thus I have table names which contain the environment as part of the table name (ex: tbl_TEST_MyTable, tbl_PROD_MyTable). Once the user sets the environment they want to use (by clicking on an option button) I update the form's recordsource to the appropriate table. My form has 5 subforms within it.
Even with the split loading the form was taking a long time because some of the queries the subforms are based on are joining tables so that they can be linked (parent/child) to the form. I created indexes to speed up the data access which helped a little but it was still running too slow. So, I attempted to change the subform's queries to only join the necessary data by re-creating the queries each time the user changes the form's current record.
For example, what I had originally was taking too long:
SELECT DISTINCT tb.*, pt.CollId, pt.ProgName, pt.QueryNo
FROM tbl_TEST_SysTables AS tb INNER JOIN tbl_TEST_Plan_Table AS pt
ON tb.Name = pt.TName
ORDER BY tb.Name;
and the parent/child link fields are CollId, ProgName, and QueryNo.
This is the change I made:
SELECT DISTINCT tb.*, pt.CollId, pt.ProgName, pt.QueryNo
FROM tbl_TEST_SysTables AS tb INNER JOIN tbl_TEST_Plan_Table AS pt
ON tb.Name = pt.TName
WHERE pt.CollId = 'BATCH_COLLECTION'
AND pt.ProgName = 'PROGRAM1
AND pt.QueryNo = 123
ORDER BY tb.Name;
where the pt fields are changed dynamically each time the user navigates to the next record in the form. This resulted in much faster access time; however I discovered that the form was always displaying the query that existed before the form was opened. I have not been able to figure out how to get the subforms to display the latest created query.
While debugging I discovered that the form's OnCurrent event was being executed 3 times before the form is opened. I don't know what I'm doing that's causing this.
I also discovered that the subform events are executed before the form's events, so I think that's why the latest query isn't being used. I attempted to requery the subform in the form's OnCurrent and OnOpen event, but to no avail.
On my master form I have a subform called invoices this is tied by Site Number to the record on the form which is has the following important information, site code. group code, exp code an amount.
On another subform via a query I have a summary of all the invoices by exp code and group code.On another subform I need to create a Income an Exp.
I have two combo boxes 1 for the Group Code, and another for the expense code what I want it to now do is look up group code exp code = Total amount. There is currently only 1 line as you will see but there will be many rows of summary data...do i need a subform for the summary?
And I need to do it this way as not all exp appears on the income and exp and I want to be able to lay out the expenses for each site differently Attached is the zip file, of the database the only record that has data is site code 0289S
Doing a school project and need to add a count function to a sub form that is based on my query. The count function just needs to be displayed on the bottom of the sub form showing how many records are in the sub form.
When I do this, the function works all good.
When I add the function to a header or footer, so that it doesn't show a column and repeat itself each time.
Hello,
I have attached a zipped excel workbook to best describe what I'm trying to do. I have table1 and table2 and I'm trying to write a query in access to get the output as shown in the workbook. I'm having hard time getting this right. I would appreciate your help if possible. Tks

I attached a screenshot with notes that describes my problem.

I have a field in a table that is to be concatenated from two other fields, PolPrefix and PolNum. On a form I got it to show the full field 'PolicyNumber' by making the control source =[PolPrefix] & [PolNum].
But this doesn't update the field PolicyNumber in the respective table, and only shows it on the form. How do I get a concatenated field defined by the user into a table so that I can call that field other places in the database?
I created two tables, let's refer to them as Cars (VW, BMW and Audi) and Colours (White, Black and Grey).
Is it possible to create another table based on these tables - i.e. in the new table the rows will be the Cars and the columns the Colours as such:
White
Black
Grey
VW
BMW
Audi
And should I enter another Car or Colour in one of the first mentioned tables, then I would like this "new" table to update automatically. For example, if I have a new Car (say, Merc), then I would like the "new" table to update to the following:
White
Black
Grey
VW
BMW
Audi
Merc
I have a problem in reflecting the updated changes on a main screen subform based on a query .These changes get reflected only after closing the access database and reopening it .Tried the requery command. Also made a macro to update the query and run it after the form opens or load but not reflecting change in main screen immediately .I would be grateful if I can get some help on this forumThanks
View 3 Replies View RelatedHi,
Im currently constructing a basic search form, which currently works. I am now trying to make the form more specified. Basically one button will give you the form that searches all records of a table. Im now working on a second button that will do the same thing, but will only show the records that the current user is present in.
The table i wish to search/sort is Changes, and there are 3 areas that a user can be assigned to a change, they can be the initiator, they can have one of the tasks of that change assigned to them, or one of the impacts assigned to them.
Initiator is part of the Change table, so thats ok. The problem is that Tasks and Impacts are subforms, and thus are stored on different tables.
Im trying to find a way to build a SQL query which will display the Change records where the current user (username stored in a global variable) is either the Initiator, has a Task assigned, or has an Impact assigned
This SQL string will then be set as the searchforms recordsource.
i've tried using DLookups but it returns an error (Syntax error (missing operator) in query expression '[Initiator] = Test User'
this is the code im trying atm
strSQL = "SELECT DISTINCT * FROM tbl_Change"
strSQL = strSQL & " WHERE tbl_Change.ChangeNumber = " & DLookup("ChangeNumber", "tbl_Change", "[Initiator] =" & UserName)
strSQL = strSQL & " OR WHERE tbl_Change.ChangeNumber =" & DLookup("ChangeNumber", "tbl_Tasks", "[Who] = '" & [UserName] & "'")
strSQL = strSQL & " OR WHERE tbl_Change.ChangeNumber =" & DLookup("ChangeNumber", "tbl_Secondary_Impacts", "[Who] = '" & [UserName] & "'") & ";"
*the inconsistency in the above code is due to my trying different things
I Have a table with 15000 entries. This table lists components we use. This table is used to generate queries/forms. I have been asked to add a hyperlink to this table to link to a drawing of the component. All the drawings are in PDF and in the same folder. I am looking for a way to automatically update the hyperlink fields all at once. The Hyperlink will be in the format of servershareddrawings12345.pdfwhere 12345 is the component name from the table.
But there are a few small problems with the component names.
1. If the component begins with a B- . The drawing name will be all the characters except when there is a second dash in the component. So if the component is B-12345-678 the drawing name will only be B-12345.
2. If The component begins with AB, The drawing will be the first 5 characters regardless of what follows, e.g. AB123.
3. Finally for all other components the full component name will be the drawing name.
Putting the naming to one side, how to go about auto generating the hyperlink. I have posted this in the table section, but maybe this should be in another section like queries or VBA.
I'm quite new to Access and am just working on a little practice database where I keep track of sales of a product.
Basically I have a table keeping track of the different types of products, a table keeping track of customers, a table for orders and one for replenishments of stock. I have a query that calculates the stock of each type of product based on replenishments and sales.
Now I want to make sure that a customer can't order any more than there is in stock. I know you can restrict what's entered into a table with a validation rule but that's only for static restrictions. After searching the internet for an answer I've pretty much learned that I can't really make this restriction directly in the table, correct? But then how can I achieve this? Do I have to restrict the amount through a form somehow?
I want to split a table into multiple sets based on rowcount. Suppose I have a table having 10,000 records. I want different sets which should have values based on rowcount. Suppose if I select set 1 then the table should populate records from 1-2500. If I select set 2 then the table should automatically give the records from 2501-5000. If i select set3 then the table should have values from 5001-7500 and so on.
View 3 Replies View RelatedI have a DB with 4 tables:
Property (used for look-up values)
Service Type (used for look-up values)
Rate Table (uses the Property Table and Service Type Table and is used as a rate look-up table for the daily service table noted below)
Daily Service
Using the Daily Service table, I need to choose a property, choose a service type that is limited to the property (100's of service types, but a property may only have a limited number), and enter a quantity, and have the Rate Table return the specific cost of the service. I didn't think this was too hard in Access (2013), but I seem to be hitting a wall and spending too much time figuring it out. Now I am behind in my project.
I have been trying to do this in a table format, but have been unsuccessful in limiting the results of the Service Type combo box based on the property chosen.
i have a table that holds "course codes" with the corresponding Module title and module codes, and assessment titles and codes that are used in each of the courses, so I have a few records that will go against one course code. I have forms set up with subforms, with the same general details on the top of each as the main details, and each of the subforms giving different information. But, for four of my subforms, I need to pull information from this table with the module title, module codes, assessment title and codes. possible to have these certain columns appear across four subforms, and what is the best way to go about it, I was thinking of using lookups?

Is there an easy way to auto-populate a Junction table [in access 2010] given the following two tables with a many-to-many relationship for Tasks? The two tables are
Table 1) tblTasks (TaskID (PK), Description), and
Table 2) tblMeasures (MeasureID (PK), Description, Tasks)
If JCTN table is JCTN_Tasks_Measures (TaskID, MeasureID), is there a way to populate when tblTasks(TaskID) == tblMeasures (Tasks)?
I have a form which is based on a select query that brings together 2 related (one to many)tables. When I keyin data to the form it does not update the corresponing table.
Is it possible for a table to be updated in such a way, or do I have to create a form based solely on the table(s) without using a query?
