Tables :: Source / Reference Of Different Data Points
Apr 24, 2015
I want the user to be able to see the source/reference of (many of) the different data points in my database, so I need to store sources/references in the database itself. I want to have all references in one single/common table (list of references). Each reference may be the source of many data points, in different columns in a given table, and in different tables. Is this possible, and can it be done in an elegant way?
I have broken up by master database, table, into several tables. They all share the same ID values since they came from the master table. So each table that I split off has a unique, matching, identifier, ID, in both the master table and the new table. Plus a previous matching identifier listed immediately below.
Example: Permit the master or main table and Builder a supporting table. There are five tables that I split off and all have an identifier similar to the two listed below.
Permit->ID Permit->BLD Builder->ID Builder->BLD
All my tables have the same ID. But each table also has a identification numbers such as builder BLD, Subdivision SB and inspector INS>
Permit has the BLD, SB and INS
Builder has only one occurrence for each builder in the Permit table. As in the past it was identified by BLD number and now also ID. the use of BLD is from when I used visual dBase. The big difference here is that I have two ways to identify one is ID any other is by BLD, etc. My first thought is to identified by the BLD. I don't know why, but I guess I fear using a single "ID" to identify my various split off tables unique value or BLD.
I have a query on a form that is providing all of the information I need for everything on my form.
The problem is I don't know how to refer to a field's value in the query in VBA without having a hidden text field on the form.
I know I can reference a combo box's query to include criteria such as [Forms]![cboSelectStudent] if the control is actually on the form, but how would I refer to a value in the form's query that doesn't have a control on the form.
I've been searching for everything I can think to call this but haven't been able to come up with anything.
I'm working on my first report and am trying to get my textbox, tboJob to show a field value and not the ID. I have tried the following Dlookup in my control source with no luck.
I have a problem when storing a calculated field with two decimal points. If I set the field to double, fixed, 2 decimal points. For the field it will show the calculations as:
21.364 as 21.36 21.563 as 21.56 21.272 as 21.27
Which is how I want it to be, however when I run a summary of the field rather than showing 64.19 it calculates as 64.20, I know that this is the correct figure but is there any way I can get it to show me the 64.19?
So I have a simple table with Date, Points Earned, Points Used and Client ID number. Id like to tally the points for each client ID, after each time they either use or earn points. How do I do this?
test_id | test_Name | test_Date | test_value ------------------------------------ 1 | Company A | 01.01.2010 | 0,90 2 | Company A | 02.01.2010 | 0,95 3 | Company A | 03.01.2010 | 1,10 4 | Company A | 05.01.2010 | 1,05 5 | Company B | 01.01.2010 | 0,9 6 | Company B | 02.01.2010 | 1,20 7 | Company B | 03.01.2010 | 1,15 8 | Company B | 05.01.2010 | 0,95 9 | Company B | 07.01.2010 | 0,80
The important level is 1,00
Now I will, for each company, check:
- Is the value of ID-1 >1 AND the value of the ID-2 <1, THAN give me a 1 - Is the value of ID-1 <1 AND the value of the ID-2 >1, THAN give me a -1
In this example the result should look like this:
Code: test_id | test_Name | test_Date | test_value | test_Code_result ------------------------------------------------------------- 1 | Company A | 01.01.2010 | 0,90 | 2 | Company A | 02.01.2010 | 0,95 | 3 | Company A | 03.01.2010 | 1,10 | 4 | Company A | 05.01.2010 | 1,05 | 1 5 | Company B | 01.01.2010 | 0,90 | 6 | Company B | 02.01.2010 | 1,20 | 7 | Company B | 03.01.2010 | 1,15 | 1 8 | Company B | 05.01.2010 | 0,95 | 9 | Company B | 07.01.2010 | 0,80 | -1
Probably I have to carry out this in vba.but i dont know how I can calculate across the datapoints (rows).
I am a newbie, so please forgive me for such an easy question, but I am stumped. I attached a text file that shows the data I am working with. What I need to do is take each product (labeled Prod) and do a weekly sum on the quantities and compare against a set number to see if the quantity is lower or higher. For instance, I need to take column 12, regardless of value and compare it against set number. If the quantity is less, then I need to add the value of column 12 to column 13 and compare the summed value against set number. Again, if the sum is less than set number, I then need to take the value of column 14 and add it to the summed value of the previous step (sum of 12 & 13), then compare this new sum to set number. This process keeps taking place until I reach a summed value that is greater than set number. Once that happens I need to identify the column that sent me over the set value and hold that data. For instance, if column 33's (out of 52) summed value takes me over the set number, I want to know that it was column 33, so I can run further calculations against that value. The column header's are week numbers and I need to identify order points based on lead times and when I will run out of material. Is this beyond queries? I think so, but if it is, I don't know how to exactly begin the code in VBA either. I think I would use an If then Else stucture with a counter switch set from 1 to 52, unless comparison exits function, but not certain. HELP?????:confused:
I have some experience doing 'Update Query' using two different tables but I'm having a hard time doing an 'Update Query' using 3 tables.
I have my source table TP05XY with the fields 'Mark' 'Date' 'UTM_Edig' and 'UTM_Ndig'. Mark and Date are my primary keys (they together uniquely ID each record). I have my Observations table with the fields 'Mark' 'Date' and 'Obs_ID'. The last table is Locations with 'Obs_ID' 'UTM_E' and 'UTM_N'.
I want to update my fields UTM_E and UTM_N from UTM_Edig and UTM_Ndig. However, to do so, I have to go from my TP05XY table, through Observations table to update Locations table. Table TP05XY is joined to Observations through 'Mark' and 'Date' and Observations table is linked to Locations through 'Obs_ID' field.
I have tried a few options without success ... anyone knows how to do it?
When entering a lookup reference to a table field it pop up message saying, "you can't modify the table 1 this time as it is in use by other person or process" i have closed all forms and table reports but the problem is same to rectify ? also when going to see the realationship then there shows no relation ship developed even after the lookup reference from one table filed to another table field.
I have two tables, Table 1 and Table 2 and two related forms, Frm1 and Frm2. I want to be able to update the data on Table1 from Frm2, that is, if I change the data on Frm2, the corresponding fields in Table1 will update to the same data. I know that if both tables are open I can reference the fields on Frm1 and Frm2 with an IF statement: If Active = True And Forms!Frm1a.DoNotchange = False Then..And I know on the update query I can reference a control on a form by Forms!Formname.Control. Wll works fine.What I would like to know is can I reference a table field in the same way. For example, I have tried to use the IF Statement If Active = True And Tables!Table1.DoNotchange = False Then..Is there a way to reference the Table instead of the Form in both the VBA and the query? The problem seems to be that I have the two bound controls [Active] on Frm2 and [DoNotChange] on Frm1. (Which I need).
I'm new to access and need to modify an existing database to get a report I want to create. I'm an Excel user and could accomplish what I want to do in seconds using Excel's Lookup functions, so I'm trying to do the same with Access Dlookup.
I have two tables in my database that tracks components in a hardware product. The first table is just a list of hardware units shipped. The second table is a list of various components (and versions thereof) used in each unit. The two tables are linked by a UNIT_ID field. I need to create a report showing each unit and what the various versions of the components are. My difficulty is that the component table is does not have a dedicated field for each component and each unit can be comprised of a different quantity of components. So the tables look something like this:
UNITS TABLE: ID Customer 1 Joe 2 Bob 3 Bill
COMPONENTS TABLE: ID Component Revision 1 Main Board A 1 Blue Board B 2 Main Board B 2 Blue Board B 3 Main Board A 3 Red Board C
I want to produce a report that looks like ID Customer Main Board Blue Board Red Board 1 Joe A B -- 2 Bob B B -- 3 Bill A -- C
I setup queries to get revisions of each Board and am trying to compile into the full report, but can't figure it out. Right now I'm trying to use Dlookup to lookup data from one of the queries and insert into a larger table. I can lookup a single value fine, but can't figure out how to get Dlookup to give me the Blue Board & Red Board values for each of the system ID numbers in a master query (which would be a snap in Excel).
So basically: If a car is using multiple cost centers for a trip it divides the total mileage among the cost center for said trip provided that the user enters the same start and end mileage on all the cost centers used. And if it doesn't have multiple cost centers it provides the appropriate amount.
how to do a particular thing in Access 2010 (I don't even know if it is possible).
I have a table named PRODUCTS: ID_PRODUCT (primary key, autonumber long integer) ALLOWED_OPTIONS (multi value text lookup field: "Option 1";"Option 2";...;"Option 9")
So I can store, for each different product, none, one, or more options to let the customers choose from.
I have a table named ORDERS: ID_ORDER (primary key, autonumber long integer) FK_CUSTOMER (foreign key, linked to the primary key of a CUSTOMERS table; represents the customer that places the order.) FK_PRODUCT (foreign key, linked to PRODUCTS.ID_PRODUCT; represents the product that the customer has choosen) CHOOSEN_OPTION (lookup text field; the customer must choose ONE option among those allowed for the product he has ordered)
The problem is that I would like the CHOOSEN_OPTION field to show as a combobox, listing the values stored into PRODUCTS.ALLOWED_OPTIONS, so that when a customer buys a product, he can choose only among the options allowed by that particular product.How can I manage a multi value field to populate a combobox, in which every item stays on its line? If I use, as a query to populate the combobox:
select [PRODUCTS].[ALLOWED_OPTIONS] from PRODUCTS where [PRODUCTS].[ID_PRODUCT]=[FK_PRODUCT]
I obtain an empty combobox.If I refer to the last field as [ORDERS].[FK_PRODUCT], Access asks me to type a value for "[ORDERS].[FK_PRODUCT]", treating it as an unknown parameter.I think that the problem is that when the combobox expands, the record is not committed yet, so FK_PRODUCT is unknown (NULL?). But this happens even if I commit the record typing something in FK_PRODUCT and then I re-enter the record and I expand the CHOOSEN_OPTION combobox, that is still empy although FK_PRODUCT exists, now.Is there a particular syntax to refer to a field in a record not committed yet (something like "THIS." or "ME.")?
I have an access database with 8 tables and as many queries and forms. Our company uses an application that performs backups of other companies data, this data is imported into access into one table. The backups are scheduled to run overnight, but sometimes they do not start for whatever reason. We need to use a query to identify when a backup does not start, so therefore to identify when data does not appear or exist in the table.
This problem is only concerned with two tables. In one table i have the backups policies (Backup Policy) and the details about when the backup should run. In the other, the main table (Backup) is the actual data that has been imported. So far I have queried only the backup policies that should run, but i need to go one step further and compare this to data in the Backup table that does not exist.
Im not sure whether this should be a bit of code in the query that compares data in the Backup Policy table with that in the Backup table when it is not present.
Ideally i need something that says. "If a particular policy name does not appear in any record in the Backup table, report back a list of policy names."
OR
(Lookup a list of policy names in table backup policy,
if these policy names do not appear in the backup table, report back a list of the policy names,
if these policy names appear in the backup table, do not report back a list of the policy names)
If anyone has any ideas if this is possible, and how, I would be most grateful. Also, if it involves the use of code or functions etc I may need a little bit of guidance!!
Let me know if you need any more details of the table structures.
I have a table and a simple query that pulls results from the table. Nothing too crazy. But, if I were to go in and change some of the data/values in the query results it will change the respective data in the table. I know that this cannot be right. What do I have to do to either prevent the ability to change query results and/or prevent any changes in the query from altering the original data in the table.
I have entered one entry in to the database with the correct values (this is record 6) and everytime I enter a new record, the data is the same (I'm using a drop down list) it will automatically appear in the box. But when I goto the table that the data is stored in, each field just has the reference to the first record that the data came from.
Looks a bit like this:
ID Server Name Pattern Engine Program 6 LN1HOME 4.735.00 8.500-1002 5.58.0.1185 7 LN1WORK2 6 6 6
Is there a way of seeing the origonal data in those fields other than the Record ID Number as a reference. :confused:
I know its a lame question, Im just is a learning process at the moment.
I am new to this and i may be going about this the wrong way but what i am doing seems to do the job until now.
I am making a form that has a combo box, a few text boxes and a subform subreport on it.
The idea is that the first thing a user does is to select a name form the combo box. this name is then stored as a sring and used to set the forms record source and then the subform's (called window) source object. the string is slightly modified during the process to do this. That part works fine.
The problem arose when i included text boxes to show infomation from the selected Query thatisant show in the window (subform).
After the user selects a name and the name is used to set up the record source and the source object for the text boxes.it then displays in the text boxes the records extra data. however it only displays the first row extra data.And when other rows in the query table are selected the data in the text box stays set as the first row.
I know that this is because i haven't programed in an event that makes the text box data update when the user selects a new row.
i also realise that i would need to have some way of know what row of the quiery table the user is looking at to be able to update the text boxes.
my questions are
Is there a way to tell what row of a query table in the subform is selected ?
Is there an event similar to on selection of row or something like that that i could use to reload the text boxes?
Can an Excel spreadsheet reference an Access Table for it's data? Sort of like a vlookup, but instead of referencing another spreadsheet, I'd like to pull data in from a database.
I have a table I'm trying to query information out of. Key fields are below:
RecNo (Key) ParentRecNo Description
I need to have a "record" in the query show both the description of itself, as well as it's parent. I was hoping to use Dlookup directly in the query design. If there is no other way, I suppose I could create a temp table and look through the recordset in VBA and dump them into the temp table, but like I said; quick and dirty was the hope here, it's for my own use, and the tables aren't large 50-100 records is what I'll be pulling out when I use this.
In my contacts datababse I have a main table where all the is stored for my contacts.
I have a form that I use to enter and display the information from, Because I have more the one contact at a given company I have created a seperate table that contains all of the contact details for each office.
What I would like to be able to do is when I select a office on my form Access will populate the the rest of the fields in this section with the relevant information.
I am making a master form for three tables which ultimately form a hierarchy. I am getting all the fields from each table onto one form. By default the record source would be made up of an INNER JOIN such as below
SELECT PERSON.first_name, PERSON.country, PERSON.last_name, PERSON.street, PERSON.area, PERSON.city, PERSON.telephone, CONTRIBUTOR.registration_date, CONTRIBUTOR.fav_category, MUJAHED.profession FROM (PERSON INNER JOIN CONTRIBUTOR ON PERSON.id=CONTRIBUTOR.id) INNER JOIN MUJAHED ON CONTRIBUTOR.id=MUJAHED.id;
I'm trying to change the record source to match using the where clause instead. However the following allows me to view but not add a new record
SELECT PERSON.first_name, PERSON.country, PERSON.last_name, PERSON.street, PERSON.area, PERSON.city, PERSON.telephone, CONTRIBUTOR.registration_date, CONTRIBUTOR.fav_category, MUJAHED.profession FROM PERSON, CONTRIBUTOR, MUJAHED WHERE (PERSON.id = CONTRIBUTOR.id) AND (CONTRIBUTOR.id = MUJAHED.id);
A tip or guideline on how I can correct this will be appreciated.
