I want to be able to invoke a form from a main form that allows me to add, delete or amend records in a table related to the one updated by the main form.
As many details records are being updated, I want to retain the value of a couple of foreign keys (but be able to amend them if required) based on the value of the previous record.
I have looked at the Dlookup function and wonder if this is what I should be using. If it is, I am having trouble trying to understand how you could differentiate between the first invocation of the pop up form and any subsequent table entries. The way I understand this function is that to get the value of the previous record in the table you use "ID-1", but this would almost certainly lead to an error for records being updated for a new master record, or if the table happended to be empty then there would be no ID-1 record.
In a Related Tables, you need to enter a FK to link to the other table.You either key in the FG from memory..The standard procedure is to design the field as combo box AND use SQL to select the field that will input the ID of the other table. So, if you want to input foreign key 3 , the combo box will display what 3 is then when you selected Access will insert 3 for you.
My question is since I can later on, edit the table and change the the value to another value, and mess the whole thing up!!! HOW can I lock my first choice so it will stay unedited ? My second question is: Is this the only way to input the FK if you do not remember the exact ID number or there are thousands of records in the related table.?
Newbie here, i have two tables with 3 fields in each (code, Description and amount) what i need to do is join these two together to show data from both tables (some of the data in fields one and two will be identical, but the third fields in both tables will need separate entries for each table) the primary key would be the first field (code) ysee, the original table has been updated by a n other, some codes and descriptions changed for others so, i would like to end up with feild one, all codes from both tables, field two, all descriptions matched to codes from both tables, field three numbers matching from first table, field four numbers matching from second table.
I'm relatively new to Access and have just created a database and am wanting the database to calculate the total of two fields and store this information in the underlying table.
Example:-
Field 1 - £10 Field 2 - £15 Field 3 - TOTAL of above - I have used the calculation =([Field 1]+[Field 2])
This works fine in my form but the total value doesn't fall through to the table. It is just blank.
I am using Access 97 and wonder if this is somehow possible. I have attached a screen shot of the properties for this field (which is called 'Total' in the underlying table).
I seem to be have trouble resolving an issue whereby data entered via a combo box based on another combo box from separate tables/queries is not able to be retained when the data in the original table has been "discontinued". The database in question has changing items that are continually updated and/or discontinued. However when these items have been checked as "discontinued", the old entry data is then updated and the fields are empty.
I chose the criteria 2 for the filter just as a test as I knew there are some records with that value in the master category field.
The problem is when ever i click the button to apply the filter it clears all the data as if it has not found any records with that value.
Is my syntax and method OK? Why its filtering everything out?
The only other thing to consider is that the field I am filtering on was set up using a lookup wizard linked to a table so the values stored are a foreign key (hence the value being 2 rather than something descriptive).
I have 7 fields in a listbox (1st is the ID, hidden) from the single table. 3 of these fields are foreign keys. How do I get them to display their related values instead of the foreign key value?
Background:I'm purpose-building my db to essentially track individually cataloged items, somewhat like a library system would. I have four main tables: tblMediaItems, tblUsers, tblTransactions, and tblLocations. Users wills be spending 90% of their time on the Details form for the particular media item record they're viewing.
I'm trying to show an item's transaction history on the main form. I added a listbox (because I liked that compact presentation style) and got the desired fields to show up from tblTransactions. I figured out how to accomplish this for a single column combo box with the wizard, but so far I don't see how I would do this with multiple fields in a listbox.
I've sent a post about this before and got some of the answer from 'Dennisk'- thanks.
I want to replace composite keys with a primary. I've just made an autonumber field on one table for my new primary key and already populated it. On the foreign table ive made a new field with 'number' datatype; this field is empty at the moment.
I'm not sure how to update the foriegn tables new field with the primary tables data. I've saw it before and remember it being easy, just can't remember how to do it.
I obviously want the numbers in the primary key field to relate to the correct records in the foriegn table.
Anyone know what the query is or if there's another way?
I have what I think is a normalised database that uses foreign keys quite a bit.
For example if I had a 'contracts' table which refers to 'clients', then there would be a tblClients, where each client has a primary key. The tblContracts would then refer to the relevant client via that clients FK only which would be linked to the client's PK in tblClients via a one-to-many relationship.
If I need any user for any purpose to see contract related information that makes sense to a human being, I simply construct a query with the necessary relationships that will show client information alongside contract information by substituting tblContracts' client FK with required information from tblClients via the appropriate relationships.
I think that is reasonably basic stuff (hopefully correct practice!)
But what about when I come to import a block of new data that needs to go into tblContracts? I'm not going to be given a list of client keys (obviously) I'm going to given their real names.
MS Access has (in theory) all the information it needs (via the relationships) to substitute client IDs (keys) for their real names and thus slot these IDs into tblContracts with the new data as appropriate, but how do I make it do this? (I know it could kick out errors if there are any duplicate client names, but let's put that to one side for a moment).
I noticed that when I made a few changes to one of my queries, the results in my data sheet view were in some sort of Asian looking language. See below. Why is it doing this? I've only been using English with this program and have not changed any of my settings so I'm very confused. Also the other fields are in English. This one field is the only one I'm having issues with.
I created 2 table that are linked to a link table so to get a many to many relationship.I have a table for locations and a table for parts.One location can have many parts and One part can belong to many locations, that is way the many to many relationship.
how to get values from the parts table to the Location table using the linked Primary Key in the foreign key linked field.The values also have to be interactive, if I change the value in the part table it needs to update in the location table.
What can I put in the field of the location table to get a specific value from the parts table?
I tried setting the field to calculated field and put the Dlookup function but that didn't work. The lookup wizard seems to be the solution, but I can only create combobox or list box and I need to select the value manually. I just need a value to be put automatically by looking at the foreign key.
If I put the Dlookup function on the default value, those it update if a value is changed in the part table?
I used to import excel data into access successfully, many times but now I have to import excel data into an existing Access table with foreign key fields, which makes me problems.
Its just doesn't work...and Im sure the forien key fields are the prob cause, the other fields are going well ...
I'm trying to update the account number via an input box with a do loop but I don't have the code right. The at the input box, the user will type in a 4-8 digit number and it will update all the account number fields in a table that are null.
I have a report that selects and shows records where a specified date field is within the range of 2 dates that the user enters.I created 2 unbound textboxes on the report with a Shortdate format and InputMask 0000-00-00;0;_.When user enter correct dates, then everything works fine: selection is properly done, the right records show up.But I have 2 problems:
1-the input mask is not working: the user can input anything! 2-the 2 unbound textboxes do not show the dates entered by the user.
It seems the value entered bu user does not go straight into the unbound textbox. How do I either intercept the value entered by the user directly into the unbound textbox or via a variable?
I am making a dp for end of day sales, and i want to compare data in a table to the numbers inputted in a form and see whether this value is higher or lower. the table displays the target sales figures for each day, and the form allows the area mangers to enter in the current day figures.
I have a database of experimental products. The database allows test technicians to input test information as well as product information (obviously in separate tables). Therefore before a tech logs test information, they have to first make sure the test product is in the database. They can do this by looking up the products that are in the database, and if the current one isn't they can input its information. In the lookup section you can also click on an individual product and lookup its test history.
What I am looking to do is add a button in the product information screen that allows the tech to open the test information input form with the test product information already loaded into the form. The product information portion of the test input form, is two combo boxes, one indicates the test products group and the other is the product number.
Looking up information on Google looks like i might need to use the OpenArgs function, however I have never used that before.
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 add a combo box to a form, where depending on the values entered in the box another combo box would show more values. In other words, if the first combobox had choices of 1, 2, 3 and 4, if 1 was selected the next combo box would have values a, b, c and d. If 2 was selected, it would have values of a, d, e, f and g.
I'm trying to make a report that a untrained user can use to review the relevant data from the database I'm creating. All of the work I've done so far has been directly in the tables . Here's a quick outline of my general data organization:
Basically, I want the user to select a department to view using a combo box or option group (which I'm not sure of how to do in a report). Then, I want to view the employees within that department sorted first by whether or not the Needs_Work check box is selected, and then by how many of their competencies are unchecked.
I have a unbound text box being used as a label. In the control source of the text box I have a date ie. =#12/31/2008#. I am using this date for criteria in a dsum function, so whatever date is in this field effects the data being displayed. I need to be able to have the user edit this date when necessary. I created another unbound text box and put the following code in the after update: Me.ReestDate.ControlSource = "=#" & Me.EnterReestDate & "#" This is working as it is displaying the correct change. My problem is that the control does not retain the date. When I exit out and go back in, the original date is still there. Is there some code that will save the field after I update it? Or maybe another suggestion to do what I need. Thanks Gregg
I an trying to create a data entry form (IndividualsEntryFm) to input data for fields such as (First Name),(Birthdate) etc., these to be saved to the (IndividualsTbl)
I also have another table (NamesTbl) which has family names etc. The two tables are linked by a (MainID) field. I want a combo box on the individualsEntryFm so that I can select the family name. Then I wish the empty fields for the IndividualsTbl to be available to enter data.When I press the save button I then want this data saved, together with the MainID from the combo box to the IndividualsTbl.
I have set the IndividualsTbl with a (PersonID) field as an auto number each individual therefore has a unique PersonID but may well share the MainID. I'm trying to link many people to the same address.
I would like to filter data from a table using a query (from an data input form). The objective is to output all results if input form field is empty and to output results higher or equal to the type in the field if field is not Null. The query code is as follows:
I was assigned by my manager to design an Access database system that is able to import all data from excel file monthly and creating charts & tables to analysis how each sales people and industry perform.
We originally have a big excel master sheet that has more than 10 sheets. I tried to import the current excel into access, but then i realized that this is not gonna work. because for next month, there will be new data and I can't do the whole import process over and over. Plus, after this system is designed, the users will be someone who has no knowledge in access, so i need to create a user-friendly system for them to use.
My questions is:since the data is always cumulative number, if I imported current excel file into access, when the next month comes, how to update the new data into excel. p.s. EXP. Mike's sale volume is different each month, and with the access system, for that column, it will be a cumulative number, like the total from the month of November to this month. how do i achieve this kind of update/import goal?I tried to link the excel to access, but by doing that, I will not be able to set relationship or change the attributes of any data type in access.
