Querying A Related Table.

Dec 9, 2007

I have a very simple database with two tables. One stores Schools that I work for and the other holds people that work at that school.

I have a form that displays information from the schools table and I have a button that I want have open a form that displays the people that are related to that school.

THe problem is I can't figure out how to limit the recordset to just the people from the school record I was just viewing.

For example. I am looking at a record with School ID 1. I want to run a query on the People table that will return just the people that work for school id 1. I just can't figure out the criteria part.

Any help is appreciated.

Thanks

Querying Two Inter-related Field In A Table

Jun 16, 2005

Hi,

Need some help. Here's the problem:-

I've two fields in a table (A & B)

A B
1 Null
2 Null
3 1
4 2
5 3
6 5
7 Null
8 4
9 6

The fields are somehow related where values of B (unique) is taken from A(unique).
I trying to do an SQL such that if I input a single value A=9 or 6 or 5 or 3 or 1, the following should be the output:

A B
9 6
6 5
5 3
3 1
1 Null

Or in another case where I input a single value A=8 or 4 or 2
the following should be the output:

A B
8 4
4 2
2 Null

How can I do that? Many thanks in advance!! :D

Continuous Forms And Querying Another Table

Jan 23, 2006

I have a continouus form that queries a table and displays various fields on the form. For each record in the master table displayed on the continous form I also need to show the result of a calculation in an unbound field.

The calculation needs to be based on the Count of the rows of a particular type in another table. This other table will have many different types of record - and I have a query that returns the count. This query is based on a SQL WHERE clause that is fed in a value from a field in the master table. To be concret a field in the master table has the name ID_component. This field has to be then used in the query to determine how many rows in this other table has a type of ID_component. From what I can tell right right now is that the query which is triggered from a combo box in the form is not getting the ID_component value on a record by record basis.

My question therefore is whether using continous forms one can get an unbound field to do a query on another tabel when the query has to be fed in a parmeter from a field in the original tabel?

If this is not possible - any ideas on how I can achieve something similar to I can obtain a count of rows and feed it into a continous form

thanks in advance

ComboBox Querying Table, Returning Null ?

Aug 8, 2005

Is anyone else experiencing similar problem ?

Basically here's what happen:

1. User need to look up item name, while in a subform. He pressed F5
2. A form showed up, with a ComboBox (which got its values from a query)
3. User chose an item name in the ComboBox, and then pressed the Close button
4. The item name got copied into the subform.

Problem is, for some items/records, step 4 doesn't happen :eek:
When I investigated, turned out that for some records, the ComboBox returned null (instead of the selected record)

This is on a 5800+ records table, on Access 2000.

Here's the code :

[Forms]![005_cashier].[subform_0051_enter_sold_items]!selling_price = Me!item_name.Column(2)
[Forms]![005_cashier].[subform_0051_enter_sold_items]!quantity = 1

The second line always works (always got copied to the subform properly), while the first one only works with certain items/records.

I've examined the offending records, but couldn't imagine how they'd be able to make Access to behave like that.

Any ideas ?


Thanks,
Harry

Querying A Table Multiple Times Based On Output

Feb 12, 2006

Hi,

I need to run a parameter query in which you enter a product number and the query (a) returns the list of components and (b) then automatically reruns the query for these components. In other words, I enter an input (a product number) the query gives me outputs (component numbers) and then reruns the query with each of these outputs as the input (i.e. I want to know what are the sub-components of these components). This process stops when all the components are raw materials -- this will be easily identifiable.

Does anyone know how to set-up this type of query?

Thanks!

Queries :: Querying Time Range On Linked Table Does Not Work?

May 8, 2013

I have a linked table in my access accdb file to a view on a SQL Server DB.

One of the columns is a date column, where only the time value is important, so it's stored in the default format, like 12-30-1899 12:00 AM.

In SQL Server, I can query records that fall between a certain time frame. It works in Access when written as an ADO query (that's another story), and it also works when I convert the view to a local access table.

But when I query it as a linked server, it will return everything is greater than 12-29-1899 11:59 pm, but when I try to search any date/time ranges on 12-30-1899 nothing is returned. This seems to be a bug in Access.

The reason I no longer use ADO, is that the results would not print. For some reason, when I go to print preview, Access would evaluate the query I'm passing through to SQL Server and throw a syntax error. I miss ADP.

Stock Symbol Table And Look Up Data Type In Related Table

Jul 10, 2012

I previously created 2 tables:

One lists all the stock symbols and company names = SYMBOL
The second table lists the purchase information for each stock = PURCHASE

I then created many queries, etc. using this data. Symbol is the key link between the various tables, queries, etc.

NOW that I understand the lookup wizard in the data type, I would like to change the symbol field in the purchase table to a Lookup field. I, of course, receive a message. I am told to delete the relationship with the other tables. If I remove the relationships and change the data type, can I then replace the relationship with out damaging all the queries and forms?

Using Foreign Key To Get Related Values From One Table Onto Another Table?

Sep 25, 2013

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?

Table Related To A Field

Nov 21, 2006

Hello

Could you help me ?

My problem is :

I'm developing a ms database for the a "repair service" .

I created a table witch contains basic data from customer, including its unique ID number (key field), name and contacts ...

Now I need to store the "repair service" data from each costumer ( its time consumption, replaced materials...) in a separate table but, If I'm thinking well, I must have a table for each costumer so, I will need to link each individual "repair service" data table from each costumer to each costumer itself.

Do you know how to do this ?

Lots of thanks in advance,

Miguel

Updating A Related Table

Jun 26, 2007

I have two databases, one containing the tables and one containing the forms and queries. The forms/query database is built from linked tables from the tables database. I would like to expand one of the fields from 7 characters to 9 characters. I planned on doing the in the table database, then updating the linked table. However, the table I need to alter has relationships with about 10 other tables and I get the (you cannot make changes to a related table error message). Is there a way I can make this change without deleting all the relationships?

For future reference, should the relationships have been created in the form/query database?

Thanks, N

Calculating Value From Non-related Query And Table

Aug 30, 2007

Hi, I'm a total newbie at Access, and know nothing about scripts. I've been operating at the level of using the Wizards and drop-down menus. I am trying to create a report that does two things:
1. Displays the results of queries that sum data from a table (I think I have this figured) and
2. Displays those sums as a percentage of a number that is input each time the report is run. (This is only one number that comes from a totally different place and has no prior relation to the data.)
Any help/advice that anyone could offer would be much appreciated!
Thanks!

Tables :: Related Table IDs Not Updating

Dec 3, 2012

I'm not sure why a couple tables are not being updated after entering data. I think my relationships are correct. I've attached the database.

steps:
open Main form
add addres then try to add an owner. it doesn't work the first time but it does work the second time. add test data and that works. now if you look at the related tables (OwnerInfo, WellLocation, TestData) they all have p_id which is the wellLocation Id

now open gernalinfo form
enter in info (tests requested doesn't work right now but you can click on them in the tbl GeneralInfo)
Now if you go to the table OwnerInfo and TestData the key p_id has not been updated. But it's there in WellLocation (ID).

Why are these tables not getting updated?

3 ORD9F0000
4 ORD9M0000
5 D90000VLO
6 D90000JOO

How would I design the table to allow me to define alternatepart numbers and also related parts? For example:

Record 1 is the primary part and record 3 is the alternatepart.
Record 2 is the primary part and record 4 is the alternatepart.
Records 5 and 6 are related parts to records 1, 2, 3 and 4.

I have a form that allows the user to select a part and displaythe part data. But I also want the alternate parts and related parts displayedon the form, maybe in a subform with tabs. I havent gotten there yet because Icant determine the table design.

Table Design Question -- Baseball Related

Jul 15, 2005

Hello,

I'm not sure why I'm drawing a blank but I am. Could I please get a few suggestions on how you might organize these fields into tables?

These are not baseball stats fields. I'm keeping track of how often teams win over the years. I would like to do generate a team webpages showing all historical wins, losses and championships.

TeamID
TeamName
Year
Wins
Losses
AL_DivisionChampion (3 divisions in each league EAST,WEST, CENTRAL)
NL_DivisionChampion (3 divisions in each league EAST,WEST, CENTRAL)
AL_WildcardChampion
NL_WildcardChampion
ALCS_Champion
NLCS_Champion
WorldSeriesChampion

Initially I thought about YES/NO fields but there are so many variables. I need to know STL won the division but also that it was the NL Central.

Any help would be greatly appreciated.

Thanks
