Linking Values
Apr 16, 2005
Hello,
I'm not familiar with Access very much and this is my situation:
I've got a table Routes with RouteID, Route, Route_price; a tabe Invoices with InvoiceID, Units, Route, Route_price, Total.
I've got a form, where I input Units, choose Route from the combo box.
Needed action:
I input Units, then choose Route, the corresponding Route_price should be chosen, shown and multiplicated with Units. The Total must be shown.
The Route, Route_price, Units, Total must be saved in table Invoices.
I don't know how:
pick Route_price according to selected Route and multiply it with entered Units and then show Total.
store all values in Invoice.
Will be gratefull for help

Hey all,
I'm not sure whether I should put this in two separate posts, but here goes...
I have just started constructing a database which has many levels.
Some of the field records may not have an entry (as they may not be known) and calculations must be done between these levels. The bottom level is in the form of matrices and I am unsure of what implications this could cause to implementing them in the calculations.
1) I assume from what I know that non-values (or empty record fields), will not work in queries (i.e. they will not be ignored, they will be given a value such as 0 to be used in the calculation). I therefore ask, is it easier to exclude these non-values from the query - or is it better to assign a default value such as -9999, then filter these values out?
Would it be easier to do this exclusion using a filter, or using code?
2) My second question may not even be possible but...
My calculations will involve using values from matrices. I am not sure of the most effective way of using these values in a query? I think there are several options, of which, these two may be the best options.
- turn a matrix from Excel into a table in Access (will mean lots of records - but can be done)
- link a matrix in Excel to an existing query in Access.
Now, the second option may not be possible, but what I would like to do is link a certain cell from Excel to a certain query - depending on the calculation.
i.e. Cell A4 used in Query1 and Cell A5 used in Query2.
I am sorry that I am so ignorant in these matters, but I have been asked to find out what the best way of approaching this is.
Thankyou all very much for your time, I hope what I am trying to achieve is clear!
Kindest regards,
Matt.

I have parts that go into and out of inventory. Each time a part is removed or returned, the user inputs the number into the computer. I was wondering how I could link the numbers so that as parts were removed or added, the total number in inventory and the total number on the floor automatically changed. Thanks so much.

I need to display a value from a table in a text field on a form based on another text field on the same form.
The table has records as follows:
Month/Year xx Month No xx Year No xx Month ID (xx shows break in columns)
Jan-06 xx 1 xx 2006 xx 24
Feb-06 xx 2 xx 2006 xx 25
Mar-06 xx 3 xx 2006 xx 26
Apr-06 xx 4 xx 2006 xx 27
May-06 xx 5 xx 2006 xx 28
Jun-06 xx 6 xx 2006 xx 29
Jul-06 xx 7 xx 2006 xx 30
In one text field I use the DateSerial function to calculate the value of the previous month (e.g.Jul-06). I need to return the MonthID value to the second text field based on the value stored against it is the table, so in case of Jul-06 it would show 30 in text field 2.

i have 2 tables that i am linking on a field that matches with null values on both tables but it either pulls nothing or when i put a right join pulls just one tables data.
i have also confirmed both are pulling from the same data source, so no issues with field properties and confirmed they are null values in each field within both tables.

OK - I'm a bit of a novice at access and the answer to this may be very simple but any help would be much appreciated.
I have a problem getting a Combo box field in a table to link to another table and input a relevant value in another field of the same table. Here is what I've got:
Table 1 - Client
Fields - CLIENT ID, CLIENT NAME
Table 2 - Client Rates (The rates charged to the client for 3 specific items that do not change)
Fields - CLIENT ID, SC, LX, SX. (These last three are the codes for the items and the values in the field are the currency values for the items as they are charged to the specific client)
Thanks
Table 3 - Job Details
Fields - JOB ID (Autonumber for the Job), CLIENT ID (Who the job is for), ITEM (This is a combo box that selects between the items i.e. SC, LX and SX), RATE (I want this to recognise the item chosen in the previous field and display the corresponding rate for that item and for that client - This is my problem!) :mad:
I will attach the database as I currnetly have it so that you can see what I'm talking about. As I say - any help is muchly appreciated
Thanks muchley

I have a combo box field called "investigations" on a patient database which can allow multiple values. Each of its values represent the different investigations a patient can do. Now those investigations are tables and forms in the database. how can i program the database to simultaneously open these forms "on update" of that field-investigations?

I'm pretty good with setting up a very simple database such as inventory, profiles, etc.. However I'm creating a database to keep track of a football (soccer) team's players and match statistics.What I have so farsample attached)
Tables:
* Players - PlayerID, Fname, Lname, position, goals, assists, etc (all details regarding a player)
* Position - Positons (Table containing positions eg: defender. Data is selected in player's form as a combo-box)
* Competition - Competition types (Cup, League, Friendly. Data is selected in Match's form as a combo-box
* Venue - similar to Competition table
* Opponent - Similar to above two tables
* Match - MatchID, Competition, Venue, etc (form corresponding to table attached)
Forms:
* Player form
* Match form
Now as shown in the sample, I choose players using the combo-box. Then whatever stats they had during the match are entered on the fields provided. How to link the player (selected using combo box) to the stat fields (goals, assist, YC, etc).

I am creating a customer database for an independent insurance agency. Within that customer database, we have a lookup field that references another table "Carriers". This is where we select the insurance carrier we have placed the clients insurance with (ex. Geico, progressive, etc). This field allows multiple entries since clients can have policies with different companies.
We also have contact detail forms for each of our insurance carriers where we store information like web logins, contact phone numbers, and other notes. These forms are based on the same table as the lookup field.
I would like to create a hyperlink so, if we are looking at a clients form with all of their contact info we can click the insurance company in the carrier field and it will bring us to the contact details form of that carrier.

I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).

I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?
So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.
If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.
For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.
So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.
There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.
A few notes.
1.Getting as close as possible to the requested number is a requirement.
2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).
my table (NR_PVO_120)
Row OtherID Fax
1 11098554 2063504752
2 56200936 2080906666
3 11098554 7182160901
4 25138850 7182160901
5 56148974 7182232046
6 56530104 7182234134
[code]....
A few sample outputs
one solution is taking rows 1-6 and 26.
OtherID
11098554
56200936
25138850
56148974
56530104
56148975
Another solution is taking rows 1-4 and 10-14.
OtherID
11098554
56200936
25138850
56024315

In Access 2010 I have a Data Entry Form on which I have an unbound textbox in the header that the user can put a default date in. In the body of the form is a bound textbox that records the date and the default value is set as =defaultdatestat (obviously the name of the box in the header).
Problem: The default date shows up perfectly until a value is put in any of the other text boxes.
For further info : If you put values in text boxes default value disappears; if you then push escape the default value reappears when the values in the text boxes disappear.

I have a query with an INNER JOIN and ORDER BY that is working great. Now, using the same JOIN, I need to update values in one table with the values in another. I thought it would be simple until I learned you can't do an ORDER BY with an UPDATE. Is there another way to achieve the same result? If you remove the 'ORDER BY', the statement below doesn't produce an error but the results are not correct:
UPDATE TableA INNER JOIN TableB ON (Left(TableA.CDN,6))=(TableB.CDN)
SET TableA.HCC = TableB.HCC
WHERE TableB.HCC Like '241*' AND TableB.BBB = 'X' AND TableA.CCC = "1234" AND TableA.HCC IS NOT NULL
ORDER BY TableB.HCC, TableA.CDN;

I have several result fields which are all drop down lists. I want each result field's drop down list values to be different depending on the selected value of the Test1 drop down list.I came up with using the .rowsource keyword. My syntax seems to be fine but I'm not getting any values under the result fields when I run the form.Here is my code so far:
Private Sub Test1_AfterUpdate()
If Me.Test1 = "Stress Echo" Or Me.Test1 = "Stress SPECT" Or Me.Test1 = "Stress PET" Or Me.Test1 = "Stress MRI" Then
Me.Test1Result2.RowSourceType = "Value List"
Me.Test1Result3.RowSourceType = "Value List"

I'd like to create a query which will consist of simple SELECT statements as follows:
SELECT [table1].[field1], [table2].[field1], [table2].[field2]
FROM table1 INNER JOIN table2 ON ([table1].[fieldX] = [table2].[fieldX]);
The challenge arises b/c instead of joining on equal values, such as the following:
[table1] INNER JOIN [table2] ON [table1].[field1] = [table2].[field1]
I would like to join based on equivalencies, such as:
[table1] INNER JOIN [table2] ON [table1].[field1] = 34 is equivalent to [table2].[field1] = 2;
I do not know the proper syntax, so this is where I need help. I tried to search online without any success.
I appreciate your help in advance.

I'm trying to determine the SQL to return only those records in a table which have duplicate values in each of two fields, but different values in a third field. Here's an example:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A123 Apple Fruit
A123 Apple Fruit
A123 Grape Fruit
A456 Potato Vegetable
A456 Potato Perishable
A789 Carrot Vegetable
A001 Banana Fruit
For the above table, I'm trying to return records which have multiple entries for AcctNum + FoodType, but DIFFERENT values for FoodClass. So for the above table, the query would return:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A456 Potato Vegetable
A456 Potato Perishable
It returns these two records because there is more than one record with for the AcctNum + FoodType (i.e. 'A456' + 'Potato'), but DIFFERENT values for FoodClass (i.e. one record has 'Vegetable' while the other has 'Perishable').

I have two tables.descriptions I'd like to relate and use to find/replace in bulk.
[Checking].[Description] (with the source data)
[Rename].[NewDescription] (with the correct data)
I'd like the values in [Checking].[Description] to be replaced with the values in [Rename].[NewDescription], including those that are "Like".
Examples:
[Checking].[Description] = Geico 12345
[Rename].[NewDescription] = Geico
[Checking].[Description] = Geic
[Rename].[NewDescription] = Geico

I have a travel time database that should tally the number of minutes traveled and convert them into a time (hours and minutes). I, however, am having difficulty converting the numeric values cleanly. Is there anyway to convert 102 minutes + 100 minutes + 110 minutes = 312 minutes to 5 hours and 12 minutes cleanly? I need to take averages of time traveled and hours worked but cannot do this correctly. Thank you for any help in advance.:eek:

There is a text box in a form that user can enter the value.
How can I check if the value entered by user is already existed in the record of the linked table or not?
If the value (or record) do not exist, that new value/record will be added to
the table.
If the value do exist, just show the msgbox to indicate.
How can I do that ? :confused:
Thanks

Firstly, is it possible to hide unchecked values in a listbox? I have a user with several roles and I want to only show the ticked roles in the listbox.
Secondly, can you create a hyperlink on listbox values? i.e, if I click on "Manager" in the roles listbox, it follows that to another form and opens the record about managers?

hello,
I've got a back-end/front-end Access database. The front end sits on a user's desktop. There's one table she needs to update, but cannot because it's not linked. It's table called Login that contains passwords/users names. The table did not exist in the front-end. I would like to copy it from the back-end to the front-end and link it, but when I try to do that, I don't see it in the list of tables. I do this rarely. How does this work exactly?
thanks-
