Delete Entire Column From Existing Table
Mar 28, 2006
Please help....
I have combined 2 Tables using a select * query.
I have to do it this way as the data changes.
The issue I have is that in both tables there is a common field called "Amps"
Hence my resultant table has 2 columns, Table1.Amps and Table2.Amps.
Every time this occurs I want to delete Table2 column entirely as I use this table to plot a graph.
In short- I need to know the code to delete a column from an existing Table.
Please help..

Hi all,
In the organisation that I work for employees get paid every 2 weeks on a Saturday. So for this financial year the pay period end dates have been 08/07/2006, 22/07/2006, 05/08/2006 etc
I have a column in an Access table listing various dates. I want the next column to be
populated with the next pay period end date after that date.
So if DATE is 05/07/2006 I want PAY PERIOD END to be 08/07/2006
and if DATE is 09/07/2006 I want PAY PERIOD END to be 22/07/2006 etc
How do I do this?
Kind Regards,
Matthew

Hello again.
I've got a query that takes a part number, strips off the un-needed prefixes and suffixes, and gives me just the meat & potatoes of what I need.
I'd like to insert these results into a particular column in an existing table. Say the column name is Part_Number and the table name is CompletedWork. What would the SQL look like for that? I think this is relatively simple but my SQL skills would never be found in the same sentence as 'good'.
TIA for the help. This forum is an incredible source of information.

I read somewhere that the main difference between JET AND SQL server is that a query rn through JET transfers the whole table across the network to the client machine and then processes it. Whereas, SQL server just transfers the particular record, say if you use a stored procedure.
Is this actually true?
What about if it's usng a SQL back end?
Any links on this subject?

I have one table that will consists of about 1,000 rows. I have another table that consists of product codes that we want to exclude from the report. I know how to include the two tables by joining, but I want to EXCLUDE the 2nd table of product codes. Basically, if any of the product codes listed on table 2 are on table 1, I don't want them to appear. So how can I do an exclude function in a query?

Is there a way to import the records from another database table? I have an inventory database, blank, only the backend data is there. So everyone goes out on their own and gets inventory. At the end of the day, I would like to get flie 1, file 2, file 3, and only open file one, and only import the record from the other two inventory tables.
All these files will be exactly the same(Tables, queries,forms, everything). The only thing that will be different will be the data in the inventory table. Thanks for you help!

I have a table that has the following: Joint Account, Employer, Employer1...Employer20, subemployer1, subemployer2... subemployer5, addemployer1, addemployer2... addemployer5, removeemployer1, removeemployer2....removeemployer5.
It might be possible that any of the columns with the word "employer" in them have the same number in them. The Joint Account column might have the repeating number in it as well.
I want to be able to push a button on a form open a input box and enter a 7 digit employer number and search through the whole table and return all the rows where that number particular number is.
I have tried building a query using "like" in the criteria but you can only use that 8 times.
I have searched through this forum, but I am unable to find something that I could use. As I m not a seasoned access user, I do not quite know what to do with some of the other "search" questions I have seen.
Thank you in advance for any help that could be given or pointing in the right direction.

Hello,
I am currently working with a database that has a table called "Students." I need to import records from a textfile that has a bunch of records, some new, some existing records but updated. I got them to import into a table used for imports (called "Import Table") and I was able to run a query to append the records if they were not already existing, but how do I get a Query to do both new inserts and updating existing records with new info from the imported data?
i.e.
Bob is in the database already, but needs to update his records. His updated record is in a textfile which is now in the "Import Table". But in that same textfile/table, there are some new people that need to be added.
Thanks!!!

-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 am trying to change all the fields of a table from All Caps to Propercase. I have used strconv propercase before, however only on a field by field basis. I have about 5 or tables that I have to do this to and am trying to save the typing. I know I can do this with a recordset (easily in asp), but am not familar enough to do this in vba. Can you do a for each fld, like in asp, or am I going at this the totally wrong way. I tried using an update query with the *, but access doesn't like that too much. Any help is greatly appreciated.
Thanks,
Josh

I'm a relative newbie and I'm trying to figure out if I can link individual rows in one table to entire whole tables.
Example:
I have a table with the following fields:
Ticker Quote Volume
MSFT $25.00 3000000
IBM $30.00 1093837
SNDK $20.00 5959483
Now each of these Tickers has a whole table of options associated with each particular ticker and the EASIEST way for me to proceed would be to simply link row MSFT with an ENTIRE table of MSFT_OPTIONS then link IBM with the table IBM_OPTIONS.
Keep in mind that I don't have a field called TICKER in the options table and MSFT does not appear anywhere in the options table.
I know I can go and add the TICKER field to the OPTIONS_TABLE and then assign a primary key and then link them both but this would involve a great deal more work since I have hundreds of stocks with options tables to link. The data I get is in a specific format and I don't want to have to massage the data too much.
I appreciate your help,
Mr. Opine.

I need to convert an entire table to lower case..
The table happens to only have one column in it, so each record only has one field..
How do I convert the entire thing to lower case?
I can not just convert the display info to lower case, this table is used as a cross-reference data table and I need to physically convert all the data in the entire table to lower case.
Oh, and I need this to be a macro of some sort, since the data is re-imported on a regular basis, and will re-convert to upper case on the import.
Thanks,
Bill

I have a form with two unbound text boxes: HireMovieID and HireCustomerID, and a button HireButton which runs my query: HireHistoryQuery. Then I have a table: HireHistory. In my HireHistory table, I have my CustomerID's along the top as column names. Then the records for those columns are in this sort of format: "0001 on 19/05/2006" as type Text.How can I make it so that when a user enters a Customer ID (e.g. 23) into my HireCustomerID box in my form, it shows column number 23 and all it's records?
Also, what code do I need so that if someone enters something into the HireMovieID text box in my form (e.g. 0001) it shows all of the instances of that from the whole table in its respective column?

I have a local table that I am trying to append to a linked table. The fields are exactly the same. When I try to append the entire local table to the linked table I get an error code.
ODBC- insert on a link table failed.
[ctreeSQL]-17002 CT- Key value already exists in index (linked table field) (#-17002)
If I specify the criteria in the field to refer to a specific value in the local table, it updates it just fine. I want an append query because I don't want to manually update 500+ records!! I don't believe an update query would work because the values are not in the current linked table... so nothing to update!

I have run into an issue with a basic DLookup. The database has grown in size and now we could have multiple entries, but I want it to return a certain one. So the information could be in it three times. Of course DLookup stops after the first one. How do I get it to loop to check the entire table? Someone mentioned to me to use a recordset, but how to write that as I have never used it before. Below is what I was using until this new request came up.
<code>
Private Sub txtloan1_AfterUpdate()
If IsNull(DLookup("[loan1]", _
"settlement", _
"[loan1]=""" & Me.txtloan1.Text & """ AND [status] = 'Open'")) = False Then
Cancel = True
MsgBox "Test", vbOKOnly, "Warning"
End If
End Sub
</code>
This was also executing after the user entered the information within a text field. I did not want them to enter all the data and then have it come back as a duplicate.

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?

Hoping someone can help me with this DELETE query. I have a Main table that's being updated by a Temp table that's an exact copy of the Main table but with a subset of records.
1) Insert records from Temp table NOT found in the Main table - this query I have worked out below - not tested, but the results look correct.
Need Help Here...
2) Delete Records from the Main that are not found in Temp table with an exception...only DELETE records where certain key fields are matching. i.e. If S.CAD_NAME, lngStoreNumber are a match to what's in the Main table. While
Temp table:
lngStoreNumber - CAD_NAME - lngcomponentSerial
1 - "CHK" - a
1 - "STK" - a
2 - "CHK" - a
Main table
lngStoreNumber - CAD_NAME - lngcomponentSerial
1 - "CHK" - a - LEAVE (EXISTS In Both Tables)
1 - "CHK" - b - DELETE (lngStoreNumber & CAD_NAME composite Found /lngcomponentSerial NOT Found in Temp)
1 - "STK" - a - LEAVE (EXISTS In Both Tables)
1 - "RMM" - a - LEAVE (lngStoreNumber & CAD_NAME NOT Found in Temp)
2 - "STK" - a - LEAVE (lngStoreNumber & CAD_NAME NOT Found in Temp)
2 - "CHK" - b - DELETE (lngStoreNumber & CAD_NAME composite Found/lngcomponentSerial NOT Found in Temp)
3 - "CHK" - a - LEAVE (lngStoreNumber = 3 Not in Temp table Subset)
Rule: Only delete the records for a particular CAD_NAME and lngStoreNumber from the Main table leaving all other CAD_NAME/lngStoreNumbers.
I'm running these updates in batches of lngStoreNumber. So the Temp table will only contain subsets of what's to be deleted from the Main table thus the need to link on the key fields only NOT to delete a Subset of lngStoreNumber/CAD_NAME. I think I've tried every possible query that doesn't work.
Here is query #1 to insert records missing from the Main table that exist in the Temp table. I think what I need is a variation of this???
SELECT D.*
FROM Main AS S RIGHT JOIN Temp AS D ON (S.CAD_NAME=D.CAD_NAME) AND (S.lngcomponentSerial=D.lngcomponentSerial) AND (S.lngStoreNumber=D.lngStoreNumber)
WHERE S.lngcomponentSerial is null AND S.CAD_NAME is null AND S.lngStoreNumber is null;
THANKS.

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 need to categorize 35,000 cells of data in a column into 3 different groups (A,B, and C). Each cell will have something like "G00001" or "G00525" in it, but depending on when it was added, I want to change it to "G00001A" or "G00525C". I created a select query to show only the G0000's column and the column that indicates AB or C, but i don't know how to add the letters at the end of my G0000's. Do I need to use an update query or can I do something more simple? Also, if I need to use an update query, how would I build it to do what I need to get done?

I have a table with employees’ information. I want to copy all records in this table to another existing table “WorkTimes”. I do not want to edit my employee table, so therefore I want to copy all records to another table before editing/adding information in other fields. How I can do that with a macro or module?
Thanks in advance.
