Setting Data Import To Overwrite Data On An Existing Table
Aug 1, 2007
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.
I have a table with a primary key. This table has address type information in it. I have an import *.csv file that I want to overwrite to this table. I want it to identify the primary key and then update address fields if applicable. I also want it to recognize when no key exists and than create a new record. However, I'm getting an error because the primary key exists and then it doesn't update the other fields. PLEASE HELP ME. How can I overwrite data in a table?
I have a table, which contains many fields, around 90. Out of these 90 Fields, around 40 will be imported from an Excel sheet, which has same headers as the 40 field names in my table, in which they have to get copied.
So when I import data, it copies them as new records, instead what I am looking at is, the records in Excel and in Access table has a Unique Key, so when I import data, matching with this unique key, the fields should be overwritten into those records from Excel, instead of adding new records.
E.g:
Say I have 2 records in my access:
ID(auto generated) Fab_name Issue_ID Location Remarks Data_1 Data_2 Data_3 1 Fab1 193 NY Bug OC DC MC 2 Fab2 641 DRS Error AC KC FC
Now when I am importing data from Excel with the following records:
So when I import the above data into my Access from Excel, based on Issue ID, it should update the values of different fields that are imported from Excel, leaving other fields (data_1, Data_2, Data_3) as it is.
And I need this to be written as a macro, so that user just has to choose the file, which he has to import.
I have the following statement which exports data based on a query to a .xls:
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, "qryreportsbydate", "C:Documents and SettingspdaintyDesktopRawQualityData_Weekly.xls"
This works fine it exports the data and names the sheet rawqualitydata.
The problem i'm having is when i come to run the export again Excel tells me the file already exists. What I want it to do is overwrite the data in the rawqualitydata sheet in the same file.
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 have a form that has 2 combo boxes and a list box. As I select items from each of the lists, the lists get changed. I tried setting some queries to Snapshot, but then I couldn't select from the list.
Alternatively, How can I find out where or why the data is being overwritten?
I have a table that is updated from an update query which gets its data from a table, which gets its data from a form. I have set the query to only update the current record, this is done by a macro when the user exits the input box. The problem arises when a user goes to visit past record, I would like it to not overwrite the old data with the new data. If the query was only allowed to ADD data and not overwrite then this would fix the problem!
-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].
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].
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.
I have a table that contains a notes field. What i would like to do is to append to this field in table with some more data (notes), however i dont want to over write the existing data. I would just like to add to it.
the current notes are added through the access front end, but in this instance i have a particular note that needs to be added to various enteries without overwriting existing data. I know this is to be done via an append query, any help would be great
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?
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 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.
Say I have a table [tbl1] and a recordset [rst1]. The fields in both items are the same. Now, how do I copy/dump/inject (what's the correct term?) the data from the recordset into the table?
i'm a Access novice. I have tables with existing data in numerical form, and would like to know how I can use Queries or VBA code to update these values into a new format in a new table. for example the original data might be of race type:
1 - caucasian 2 - african american 3 - hispanic 4 - other
how can i achieve this in Access? i know how i can do this conceptually with "if" and "case" statements, but I have no idea how i can do this in Access. I don't want to mess with the original data, so please help with CODE or QUERY examples.
what is the best way to import the data from the XML file into an access database table. The database I am working with has one large main table where all of the main record data is stored. There is a somewhat complex string of queries and reports based off this table that I am concerned about preserving. The problem is that the XML file is not structured in the same way the table is. The headings are named different, aren't in the same order, etc. I cannot use the import method and simply append it to the main table.After much searching around I have found two options:
1) Use the built in XML import method that access provides to create a secondary table. Then find a way to take data from individual fields in the second table and map and insert it into a new record in the main table.I already have the import part of this option working. The only part I can't seem to understand is how to take data from the second table and get it into a new record in the main table under the correct headings
2) Read the data from the XML file all at once and then map and insert it into the main table.I have not attempted this yet. I was having a hard time understanding how to retrieve the data from the XML file in the first place.
So.. which would be better/easiest to automate (most likely via button click on a form)? I only have a small understanding of VBA and even less understanding of anything XML.
I'm trying to write a query that will validate a field in an existing table. I want the query to show where any of the 412,000 records fail this strict validation:
AAnnnnnnA
...where A is any letter A-Z and n is a digit 0-9
Clearly I can use the LEN function to check for invalid lengths (anything <>9), but I'm looking for a simple neat expression I can use that will check the format. Does an existing function already exist before I resort to writing my own function in VBA (again)?
My db has multiple linked tables. As time passes and work on a project continues data needs to be added to a separate table that is linked to the first table to be populated.
i.e., Initial design data is entered first, when drilling is complete more data is added to a linked table, when drilling is surveyed yet more data is added to the second table.
What I want to be able to do is to query for a particular set of existing design data, display this on a form and on the same line enable data entry to other fields from other tables which are linked to the existing design data.
I have a database with existing data, that is not normalized, :eek: and all the data is in one field... This what I am dealing with:
As you notice the first row of data in field1 C10A CHOLEST&TRIGLY has 3 spaces to the right the next row ALTORVASTIN has five spaces to the right, the next line LIPITOR has 7 spaces to the right, and so forth, hopefully you get at what I am trying to do, I just looked at the data and it is not showing up in view of the leading spaces, but I am trying to move the data based ONLY on the position of leading spaces, example all data that has 3 leading spaces would go into its own separate column, and all data that has 7 leading spaces would go into a separate column, I have tried to use the left, mid, len functions but I cannot figure out how to move the text and keep it whole only by data position of spaces.
Field1: C10A CHOLEST&TRIGLY ATORVASTATIN LIPITOR PFIZER SIMVASTATIN SIMVASTATIN TEVA TEVA M1A ANTIRHEUMATIC N-STEROID ETODOLAC ETOPAN TARO PHARMA Thanks so much for your help... :confused:
This has to be an easy one but I can't seem to figure it out. I created a table by importing the structure from a .dbf file. Now I simply want to import other .dbf records from a bunch of .dbf files that have the exact same structure. How do Import these records into my existing table?
This should be a no brainer but I have spent an hour or so searching the help file and the internet.:mad:
I have a table with more than a million records. I want to add a new column with date equals to e.g.3/14/2012 for all the records. I am using update query, but it is super slow (taking more than a hour)..is there any other way to do this?
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.
I want to import data from one DB to another, but only data without affecting the table structure and names. In the import dialog box has only two options, import tables and data import tables only. I want the third one ;) import data only. Is there any automatic way or do I have to make a VB sub?
What I'm doing now is to importing tables and data to the second DB, but as u know this results in having every table twice like Students Students1 Classes Classes1 and so on. Then I'm removing one by one all the old tables and then renaming every the Table1 to Table. As you can imagine this is not a practical solution and it can be implemented only to small DBs, with a small number of tables. In my case we are talking about a huge DB with over 20 tables, and the above process (importing data) has to be done at least once per month.
Let me inform you that copying data and only data from one base to another is the only method suits in my case so please avoid suggesting alternative solutions.
I currently have a macro that imports data from a spreadsheet and then a query that adds the data into the main table.
But when I want to import new data it deletes the old data out of the table and inserts new data. How can I adjust the query so that it "updates" the new data into the table instead of deleting and then adding?
Another problem is empty records, is there a way of importing data where field 1 has data?
Hi guys, Iīm a unexperienced user of access and itīs my first post in this forum. Hope to make myself clear.
I have several tables. My problem is rather simple but I didnīt find out to solve it. I searched on the forum but didnīt find it. I might not have the appropriate vocabulary yet to perform an efficient search.
My problem is that I have a form to fill a sales table (Salg). For each entry I need to fill the postnumber and the location. On another table (Poststed) is registered the Postnumber and the location name. On the form I did a combobox to get the post numbers. Then to get the location, In another box, which should come automatically after the "Postnr" has been selected, it should display the "location name". I did a "DLOOKUP" for that:
and it works fine. The name come automatically. However, when I validate the "post" then all the data in the boxes are register in the destination table, but not the "location nam". It seems it is not bound to the table because the DLOOKUP function is in the source field. Does anybody knows how I can bound it to the table. Or if I should use another way to do the task, Iīm open to any suggetions. I hope I made myself clear enough.
I want to import an Excel spreadsheet into a table in my Access DB. I am using following: DoCmd.TransferSpreadsheet acImport, 0, "tblSchedule", "C:mailinimport.xls", false This code works but it is appending to the table. What is the best way to update the table - or would it be best to delete the old table and then to create a new one to import tha data into? If the latter would be most elegant solution, can anyone help with some code that would do this ? Thanks Mat
