Tables :: Normalize Existing Table Containing Data And Copying PK Value To FK In New Table
Nov 21, 2014
I am working from an existing database which is just two table. The main table has a massive amount of redundancy and duplication and needs splitting into, at first glance, 5 tables.
After I have run my various make table queries and added a Primary Key and FK field to the new tables how do I populate the FK with the Parent PK.
I thought I could simply add all the fields from the new table and then create an adhoc join in an update query to populate the PK to the FK. When I do this however I get "You are about to update 0 records"
I have tried the table analyzer but it doesn't give the correct options to split the table the way I need.

I want to be able to copy the data within a selected field and then place it into a fresh database is this easily done?
my second questions is i have several fields which need to be merged into one 'Address' field as currently i have data with Building Name, Number, Line1, Line2, Line3, County, Town, Country. This is required to be merged into one field how would i do this?
Not all fields have data is there a way to put a space between each of the current fields when merged as well?

I have one DB that is used for creating/storing customer ID's, and another DB that is used for creating/storing job information for customers.I have linked the table from the customer DB to the job DB.
There is a table in the job database that holds customer name and ID, and some VBA that generates unique job codes.
Is it possible to have the data from the linked table automatically update into the existing table?

I am looking to copy one exceptionally large table to another. I can use VBA to copy the entire Report2013.accdb to Report.accdb while compacting at the same time. This is very fast and works well. However once it's copied I need to rename the table tblReport2013 to tblReport. None of these table are in the accdb that I am running the scripts from FrontEnd.accdb. I am working very hard to keep the data tables under the 2 GB limit, which is why linking and keeping the data separate is necessary. There is the chance that Report2013 will be on the network while tblReport will be local to the user, and may or may not be a subset of the Report2013.
I have considered a number of options:
DoCmd.Rename - I can't seem to tell it a database location
I could try
docmd.copyobject - and see if it keeps the file size the same or smaller then the original.
I could just write the sql statement and copy the data that way, and compact the table afterwards. The trouble with doing the transfer that way is hitting the 2GB limit, before I can compact/compress the newly imported data.It just seems odd to have to find another solution when all I really want to to rename a table and ensure the new new is still linked as a separate table.

Hi:
I am looking for some guidance in doing the following:
I have a tableO that contains a list of objects that have associated attributes, specifically a list of system_names (object) and the associated attributes (additional fields in the table) that include port_name, port_direction. Think of each one of the records as a template that will supply data to another table, called the Instance table (tableI). The concept is that the user can populate the template with various objects and associated ports, and direction.
The table cols are;
PK|FK|system_name|port_name|port_direction|
The data for this table is manually entered via an associated form.
At some later time, the user want to make a copy of an object(e.g. a record in tableO) by populating Table I (the instance table). The first few fields of tableI are named identical to tableO. Table I contains additional fields that further refine the template, by adding a object_property field, and a port_direction_property field.
Table I looks like:
PK|FK|system_name|port_name|port_direction|prop1|p rop2
The forms interface allows the user to fill in the fields in the TableI (intance table) directly, or, lets the user scroll through the list of objects in the template table, and chose a template, copy the fields:system_name|port_name|port_direction into the same fields in table I, and then add values to prop1 and prop 2 manually.
I made the combo box control that will list the objects from the object column of the template table (table O) and make the desired selection. I have a radio button adjacent to the combo box that when clicked, will copy the selected record and designated fields from the template object table (tableO), into the same fields of the instance table (table I). The instance table is displayed on an adjacent form.
After the fields are copied to the instance table, the user can type in the data into the additional fields (e.g. prop_1, prop_2), and complete the record.
I do not know how I can do the 'copy' from tableO to table I when the radio button is pushed. I know to allow an action when the radiobutton is 'clicked'. Table O and tableI are not currently related.
Can you provide some guidance?
Thanks a lot for your time

Hi,
I'm looking to include a button on a form that opens a new entry in another table and copies some field entries from the first table into the second table. I tried an append query, but it seems to be unable to be displayed in a form. I just want to copy data from one form to another. Thanks.

I am attempting to normalize an existing database. I've created the table structures necessary and now I'm designing a query that will update the new field in my primary table: "LabelBaseProduct" with the primary key from my new table: "tblBaseProduct" where the old field from my primary table: "tblLabels.BaseProduct" equals the description field from my new table: "tblBaseProduct.BaseProductDesc".
A visual of my tables:
tblLabels (Main table)
- LabelID
- BaseProduct (old field with text data)
- LabelBaseProduct (new field, needs to be updated with PK from tblBaseProduct)
tblBaseProduct (new table)
- BaseProductID (PK and FK to tblLabels)
- BaseProductDesc (Field that should be matched to tblLabels.BaseProduct)
I tried to design a query using design view of the query design and this is what I have:
Code:
UPDATE tblLabels, tblBaseProduct
SET tblLabels.LabelBaseProduct = [baseProductID]
WHERE (((tblLabels.BaseProduct)=[tblBaseProduct].[BaseProductDesc]));
When I attemted to run the query it told me that it was going to updated over a million records. I only have just short of 2k records in my database.

I have two identical access databases. I copied the master file to my desktop to work on it while someone else was in the shared file. I edited about a hundred rows in the Data Entry table (the records exist in both files), and now I want to copy those changes back over to the master file without messing up any of the other data. I'm not sure what the other people changed in the file, I just know what records I have that need to be copied over. Again, they exist in both files, I just want to overwrite the records in the other file with my updated records without affecting other data.

I have linked a SQL table to my ms access database. In order to view the SQL table as read-only and still be able to update the access table I have setup a form with a subform.
I know it would be a dublication of data but is there a way thru code of copying the data on the subform to my access table. I was hoping I could put a button on the form that would copy this data. My idea is after the copy is done all the information I need will be in my access table. I'm new to this linking idea and am worried I will only have half the information I need if the link breaks etc.
Thanks

I have a MS Access table containing Dependent social security numbers but some of the dependents social security numbers are blank.
I have a MS Sql Database that contains a table with most of the missing MS Access table dependents Social Security numbers.
How can I take the Dependents social security number from MS Sql Database and copy/update the MS Access table.
I tried the sql code below created from MS Access and it matches 453 records out of 460 dependent social security numbers but how do I update qryGHIAccuracyFile_MissingDepSSN.SSN with the social security number from dbo_depfile1.dep_depend_ssn
Code:
SELECT dbo_depfile1.dep_depend_ssn, qryGHIAccuracyFile_MissingDepSSN.SSN
FROM qryGHIAccuracyFile_MissingDepSSN LEFT JOIN dbo_depfile1 ON qryGHIAccuracyFile_MissingDepSSN.MemberSSN = dbo_depfile1.dep_ss_nbr
WHERE (((dbo_depfile1.dep_first)=[FirstName]) AND ((dbo_depfile1.dep_last)=[LastName]));
Updating MS Access table dependent blank SSNs with SSN in MS Sql Database.

What I have is a database that I have done some tweaking on and in the meantime the original db has been in use which has added around 200 or so more records in the table.
What I would like to do is to just update the db that I have been working on with the older db table(the one who has the additional 200 records).
EX. DB A(Old DB, Newer Table) DB B(New DB, Older Table)
I want to put DB A table into DB B
Is this a simple fix? Or do I need to write some sort of query to update the records in the old table? I've tried to export the excel file and then import but it puts it in unrelated objects and then my switchboard or nothing works.

I have 3 tables
tblProductInfo
- ProductID
- ProductItemNumber
- JDEDescription
tblFacility
- FacilityID
- FacilityDescription
tblProductFacilityMM
- ProductToFacilityID
- ProductIDFK (combined with FacilityIDFK to make a PK)
- FacilityIDFK
As I'm writing this out, I am realizing that tlbProductFacilityMM.producttoFacilityID is probably not necessary, but that I don't expect that to have much significance to the issue. So I've setup a query between the two tables:
Code:
SELECT tblProductInfo.ProductID, tblProductInfo.ItemNumber, tblProductInfo.JDEDescription, tblProductFacilityMM.FacilityIDFK, tblFacility.FacilityDescription
FROM tblFacility INNER JOIN (tblProductInfo INNER JOIN tblProductFacilityMM ON tblProductInfo.ProductID = tblProductFacilityMM.ProductIDFK) ON tblFacility.FacilityID = tblProductFacilityMM.FacilityIDFK;
And used it to create my subform which is simply a drop down box for tblProductFacilityMM.FacilityIDFK. My main form is one that has already been in use for 6 months or so, it is based off the tblproductinfo table and needs to have the option to select multiple Facilities for each ProductID. I inserted the subform, but when I try to select a facility I get an error that reads:
Quote: Cannot Join Records; Join key of tblProductFacilityMM not in recordset.

-Microsoft Access 2010
-Existing Access Database contains tables with 1-2 million records
I would like to add a field[dol] to an existing table[rei]. I need this new field[rei].[dol] to be populated with existing data from another table[main] based on the associated field[main].[account1] or [main].[account2] or [main].[account3].
Table1[main]
...account1
...account2
...account3
...dol
[code]...
In the [main] table. There is always data in [dol]. But there is NOT always data in the [account] fields. Sometimes there is multiple account numbers per [dol] but not always.
Customers will ALWAYS have at least 1 [account] number and [dol]. Some will have multiple [account] numbers and [dol]. Sometimes these [account] numbers are the same in multiple fields[account1] [account2] [account3].I just need to do a lookup or something to find the [account#] and pull in its [dol] from the [main] table and populate it in [rei].[dol].

I have data that I would like to use within another system. In order for this information to work as desired I will have to "de-normalize" my tables into a single record set.
Here is the issue, I have 40k+ records that have the majority of the data I need in a single table. I have directory path links to the photos related back to the primary key.
I need to merge these into a single line of information.
Example:(this is simply an example and not the true layout)
Tbl1
PKEY De1 De2 De3
123 North 15 Blue
124 North 28 Green
Tbl2
PKEY Path PhotoName
123 M:Photo 123(a).jpg
123 M:Photo 123(b).jpg
123 M:Photo 123(c).jpg
124 M:Photo 124(a).jpg
124 M:Photo 124(b).jpg
124 M:Photo 124(c).jpg
124 M:Photo 124(d).jpg
The desired end result would look like
PKEY De1 De2 De3 Photo1 Photo2
123 North 15 Blue M:Photo123(a).jpg M:123(b).jpg
...and so on until all photos for the record have been listed out.
Any suggestions? If a search topic similar to my issue could be recommended I would appreciate it greatly.

I have a database that I import data from an excel spreadsheet into multiple times daily. The table that this data is imported into has several key fields that if the data already exisits in the table, and I attempt to import data that is the same except for one or more of the key fields is different. At this time the database it creates a different record. I am trying to get the database to overwrite the data in the database.

Please bear with me, first post, trying to get to grips with Access for work!
We (a primary school) had a "bespoke" database set up using MS Access by someone who has long left the area and now we need to make changes and I, as the most computer literate person on site, have been volunteered to make these changes.
My level is beginner (for now) and my first job is to add some new options to a "Titles" table, four columns, six records. Column1 = ID#, Column2 = Male Titles, Column3 = Female Titles, whilst Column4 seems to hold items from Columns 2 & 3.
If I add a futher option, I get the error "Can't perform cascading operation: Entry must be one of the Titles as featured in the drop-down box or in the Titles table.
Now, as far as I can tell, I HAVE added the new option to the Titles table, and they DO show in the drop down box in the main spreadsheet display, BUT the error comes back as soon as I try to confirm the new title.
Any ideas please?

I was asked to create a table within an existing database using these SQL commands;
CREATE TABLE Vehicle (reg_no TEXT(10)
CONSTRAINT VehicleKey PRIMARY KEY,
type TEXT(10),
purchase_date DATETIME,
last_service_date DATETIME, mileage_at_last_service INTEGER);
I was told to save the query and check the new table had the required records in it.
I had huge problems when I tried to save the query and kept getting error messages like: "query must have at least one destination field" and "syntax error in field destination". This was strange since I was sure I typed the query exactly as it had been written on the worksheet.
Having not changed the SQL command at all it eventually worked when I skipped the 'save query" stage and just went to the "run query" stage. I still don't know why it actually worked in the end and why I kept getting error messages.By running the query am I supposed to just click on "RUN" or can I check the information first by looking at datasheet view?

I am trying to import from Excel and append to an existing table. My excel sheet is named tblStatus and I am trying to append it to my Access table "tblStatus".
I get an error message that says "The first row contains some data that can't be used for valid Access Field Names. In these cases, the wizard will automatically assign valid field names." (I used the excel sheet to set up my table.) After I click OK, I get to the point where I can click finish, and I get a "Subscript out of range" error.
MY row headers are:
strOrderOps
strOrderNo
strOperation
strOrderType
dtmBasicStartDate
dtmActualFinishDate
dtmCalFinishDate
strStatus
I am not sure what is going on.

I have a form (frmCompany) which has two combo boxes (cmbCompany and cmbCity) which is used to add field data into a table (tblCompany). The Company field is the only required field the other is optional.
In some cases I may wish to add a City, at a later date, to an existing Company using frmCompany. I now select the company from the cmbCompany combo box then add the city to cmbCity. The problem is that when I close the form I get two companies in the table with same name, one has a city and one does not.
How can I add a new City to an existing Company, using the form, without adding a new Company?
