Tables :: Updating One Column Of Data Across Many Records
Jul 9, 2014
I have a database containing 10,000+ trouble tickets identified by a unique field called "Ticket ID". This is the primary key for my table. (It's on just one table.) These tickets came from an excel sheet that was exported out of a different database. (For various reasons, we've moved the tickets to access.)
Among many descriptor fields, I have a field called "SPR Type" that shows what type of ticket each entry is. (Bug, Defect, Enhancement, etc, etc) The problem we have here is... not all of the ticket entries have an SPR Type listed on my access table because not all of the tickets coming out of the original excel sheet had one.
I was given a new excel sheet containing 400 to 500 ish Ticket IDs and the SPR Type that applies to each of those tickets. How can I take that sheet and use it to update my access table? Ie. Use the excel sheet containing Ticket ID and SPR Type to populate the blank SPR Type fields for each of their respective Ticket IDs?
**Update: I'm trying something like this...
UPDATE [SPR Priority] inner join [EB Update of SPR] on [SPR Priority.Ticket ID] = [EB Update of SPR.Ticket ID]
SET [SPR Priority.SPR Type] = [EB Update of SPR.SPR Type]
But I am getting an error that says "Invalid Bracketing of name [SPR Priority.Ticket ID] and similar errors. What am I getting wrong here?
I thought about an Update query that would populate the SPR Type fields based on Ticket IDs. I could import the new excel sheet into a separate access table and update from there.

I have this table "tblPreventativeMaintenance" which calculates when the next appointment for service. Stored in the field "NextDueService". I have three fields in this table. "SerialNumber", "NextDueService" & "Engineer'sReport".The whole purpose of the table above is to do the calculations.Now the results of the calculations I need them to go into another table "tblInstallations" so I can use it to show Next Due Service when there is a call out in regards to certain ready installed equipment. I have same fields in both tables.I tried update query but for some reason it didn't work or at least wasn't giving me the results I needed from it.

I am in the process of building Append Queries for new records, and I know I can do an Update Query to enter specific information. However, how can I update multiple records from a (externally sourced) linked table to fill in blanks of an existing table? I have created a query to identify records with 1 or more matching criteria which contain the blank fields. I now want to update those blank fields. The data in each blank field is different for each record (same type, just different data).

I have a table with more than 60 fields and need to update it with records from another Access file with a table with an identical data structure.
Is it better to run an update query or an append query (i would have to delete the original records in the target table first) or a union query?
If I run an update query I will have to manually add each field to the query.
The update query will not add 'new' records. If I run an append it is quicker because I can use the * to match all fields, but i will have to delete the 'old' records first, as both tables use autonumber for the PK so the PK ID will be the same in each table (will get a key violation error).
If I import the 'new' table and run a union query it will match the fields and add the new records, but then i will have to create new table from that query.

So I currently have a table that tracks medication activity for patients called tblMedRanges. The Fields are the ID, StartMedication, EndMedication, Med ID/Medication Name.
In the End of Medication, some patients are not currently active so they have a set date/time field property. What I have for right now is the default value is set to
Code:
=date()
So that when staff adds a new medication it is set to the current date. These patients are supposed to be active, but it doesn't update the default value. I want it to continue to update to the current date every time the database is open.
I have three options that I know of(or think I know of) to update but can't commit to one in particular :
1)I want these individual records in the field to update the current time for today and was considering using some kind of data macro code using before update.
2)The other idea I had was splitting up the field into an EndOfMedication field that would display a value only if their inactive, and an Active field (text, value list active/inactive choices) that would be used in a query to generate the current date as med field. This would take some crafty query work with comparisons later on to generate list of drugs that they were on for each visit.
3) set to text field and convert the field to date field for comparison in queries.

I Have a table that contains the fields: CAT, CHAPTER, ID, someSrting and Completed
CAT, CHAPTER, ID are numbers and Completed is true/false. If I mark a certain entry as Complted (true), I want all the records with the same (CAT, CHAPTER, ID) as the one I marked to be updated to Completed.
For example, If I marked the entry cat:1 chapter:1 id:1 as completed (true), I want all the entrys that have cat:1 chapter:1 id:1 to be marked as completed (true)
the code I wrote is:
Code:
Private Pub Completed_check_AfterUpdate()
Dim myCC
Dim myCat
Dim myChap
Dim myID
myCC = Me.Completed_check
myCat = Me.CAT
myChap = Me.CHAPTER
myID = Me.ID
CurrentDb.Execute "Update [my Table] " _
& "SET Completed = (" & myCC & ") " _
& "WHERE CAT = (" & myCat & ") And CHAPTER = (" & myChap & ") And ID = (" & myID & ") ;"
End Sub
I'm running the code (my clicking the "check box") and nothing happens, I was thinking that maybe I defined the after "WHERE" statement wrong, and there are 0 entrys changed..
UPDATE: after removing the
Code:
"& "WHERE..."
row, the code does update the entire table, so I have a problem with the syntax of the sql..

I have created a Production Tracking database for my company using
Access 2003. Everyone here uses Access 2000, so I have saved the file
as an access 2000 database. I am importing three tables from an ODBC
connection. These tables are being update by another department
constantly. I am using a centralized form for users to view the
information.
If the users are viewing the information and we try to update the
tables they are viewing, we get an error. My question is: Is there a
way around this problem?
This what I have done:
In the module I wrote, I am importing the tables, then renaming them
to the tables the users are viewing, and then altering the structure
of one of the tables. We cannot use linked tables, the reason is we
have only three licenses to access the software through the ODBC
connection. So as soon as three people open the access database they
take those three connections.
Any Ideas?
Thanks,
Phil

This has to be a common problem.
I have an environment where I have two databases. One holding tables (The Data) and one holding everything else "The Programs" (Forms, Queries etc)
When the application gets enhanced I currently have no problem updating "The Programs" since I can just copy the new MDB on top of the old MDB.
This is not the case with "The Data", if I need to change any of the tables (since they contain live data, that is modified all the time) I have to physically connect to the machine holding the Data.MDB and modify the tables. The problem is there are getting to be many locations where these changes need to be made.
Is there any way to update the tables from a script (I used to use SQL to update remote tables in a mainframe world)
Thanks

Ok. Here's the situation. I have query setup. This query has 2 columns:
1. Agent Name
2. Sale Value
I have 2 tables.
Table1: Includes Sales for this pay period only
Table2: Includes all Sales From past to present.
We are setting up our system on Tiers and Each sale value is going to change. So, Here's what I need:
I need to run an update query that first Looks up all the records in Table1 based on Agent Name. The field that needs to be updated is called SaleValue. It needs to be updated with what's in my Query mentioned above.
Then, all the values in Table1, need to be copied (or updated) into Table2. This can be done based on the Primary Key (SaleID), which exists in both tables. So I guess we will need to run 2 separate update queries. Any ideas on how this can be done?

I have an Access db in a 3 person multi-user environment on a Windows network.
There is a "PRODUCTION" db and a "DEVELOPMENT" db.
Let's call them PROD and DEV.
PROD has the most current data, shipping records, item master, customer data, sales, etc. - but not the most current structure.
DEV has the most current struture - all the front end stuff - forms, functions, modules, etc. - but not the most current data.
The way I've handled this in the past (it seemed to work) was to take the PROD db and rename it to PRODX. Then take the DEV db and rename it PROD. Then open DEV (now called PROD) using the usual shortcut to PROD.
So now that opens fine, and I have to update all the tables from PRODX - and I mean ALL of them - since I don't really know what data has changed since the last update.If I try to delete records I get blocked by access because of all the related records (I don't have cascade delete set on every relationship). So I delete the whole table - ALL of them (this requires me to also delete the relationships). Then I IMPORT all the tables from PRODX (these have the current data). But now the relationships are all gone. It seemed at first that the relationships were back and intact - but when I last looked they were gone. So this is my problem.
HOW do I COMPLETELY empty ALL of the tables - or even delete them - and then restore them or repopulate them from an exact copy of the db but with current table data - and WITHOUT affecting the relationships?
Obviously any back end structural changes have to be handled differently. Usually by manually making the same change on the PROD db that I had in the DEV db - because deleting the table will cause the structural changes to be lost.
One last thing - I've been working this way on an un-split db, and now I'm in the process of splitting it - which SHOULD make updates much easier.

I am working with MS Access. The database has 2 tables.
-Parent and Student and ParentID is the Primary key as a parent may have multiple Students
-There is a form that lets me add students for a particular parent
One of the fields in the Parent Table is FeeDue. I added a field in the Parent Table called NumOfStudents..What I want to do is as follows: When a student is added on the Student Form, I want fee to be calculated automatically for display AND update the FeeDue field in Parent table. Event handler executed when a student is added (checkbox clicked)
OnClick()
{
Read NumOfStudents from Parent Table
if(student_added = true)
NumOfStudents++
else /* This is to cover student withdrawl*/
NumOfStudents--
if(NUmOfStudents = 1)
Fee= 400
else
Fee = 500
}
student_added check box is on the student form NumOfStudents and FeeDue are fields in Parent

I have a table in my DB called, devices. This contains all the information about various devices we have deployed in the field.
These devices are also contained in 2 other separate MySQL DB's.
What I need to do is add 2 additional field to my access table for the DeviceRecno and DeviceID of the same device from the MySQL DB's.
Adding the field is easy, but I cant think of a way to enter the recno and ID from the other DB's without typing them in manually for each one.
The common between them all is the serial number of the device, and I can get a list of serial numbers, recno's and ID in an excel sheet.
like a vlookup in excel to easily populate all the existing records with the recno and id's from the other db's?
When I created the access system there was no intention to link it to the other DB's for any reason, but that has now changed due to a lot of reasons.

I've been using MS Access 2007 for years to manage some Excel data. running some queries etc. Just recently I've been encountering problems when importing data into an existing table. When I do it now, I get a "Subscript out of Range" error. To troubleshoot, I imported into a new table and when doing so, the fields no longer match the column order of the spreadsheet. They all get imported but appears in a different order. I think this is why I am getting the error message. How can I go about ensuring that the data gets imported properly into my already existing table? My fields in "Design View" will match the order of the Columns in the Excel spreadsheet.

I've created a access database containing multiple tables, theres one main table that will contain all the data compiled.
I then have other tables that contain some matching data but with an additonal column filled in,
I want to be able to pull the data from these other tables into the main table and compile it including merging some data into a single feild.
Effectively this is what the inputs will be:
Code:
Table 1
Ident Number Solution TRN
T0941A1 SLN019149 EFE0008
T0941B1 SLN019149 EFE0008
T0941C1 SLN019149 EFE0008
Code:
Table 2
Ident Number Solution TRN
T0941A1 SLN019149 EFE0167
T0941B1 SLN019149 EFE0167
T0941C1 SLN019149 EFE0167
Code:
Table 3
Ident Number Solution TRN
T0941A1 SLN019149 EFE0188
T0941B1 SLN019149 EFE0188
T0941C1 SLN019149 EFE0188
Then the main table i want to compile the data like this:
Code:
Table 4
Ident Number Solution TRN
T0941A1 SLN019149 EFE0008,TRN0167,EFE0188
T0941B1 SLN019149 EFE0008,TRN0167,EFE0188
T0941C1 SLN019149 EFE0008,TRN0167,EFE0188
i want it to show as 1 line item and compile the TRN numbers into a single feild per row rather than having duplicates.

I am trying to run a simple update query to copy data from one column (Addrl1)to another column (Working_Addrl1) within the same file and I can't for the life of me figure it out. Then I need to repeat for addrl2 and addrl3 to working_addrl2 and working_addrl3.

I need to input a string into a column named "EventType". The code should first check if the column "Agent Name" contains any strings. If there is none, it will input "IBM Director" into the EventType column.
Once it has looped through the agent names, the code will then loop through the Details column and input into EventTypes based on what is displayed within the string.
These are the codes that I am using to achieve this, however nothing is being input into the EventType column.
Code:
Private Sub Command11_Click()
Dim dbs As DAO.Database
Dim rst As DAO.Recordset
Set dbs = CurrentDb
Set rst = dbs.OpenRecordset("Final")
[Code] ....
I think the problem lies with the code that checks the agent name. When I removed it, it managed to populate the EventType column based on the details. But I still need to find out how to check the agent name too.

My form is setup with Continuous view, with data feeding from a table. The structure is straighforward (excel style). AgentID, workHrs, holidayPaid, holidayUnpaid, sickHrs etc. The structure is not normalized, and I know the risk. This is basically only for human interpretation, not really a structure that will cause instability or patched up working of the DB.
I have the continuous form view, so it can be viewed in one single display, I have placed a Totals at the footer, which is populated by nothing but a simple = Sum(columnName). This works great in most of the computers, except one. My boss's computer. Which is where it actually needs to work. I am baffled, because I have tested it on almost every single computer in my office, everyone's work. Just his computer is playing up. I am unable to pin point the problem. The status bar keeps going "Calculating..." but even after giving it a solid 5 minute it does not seem to work !

Hi. I have a question I'm hoping someone can help me with. I would like to take data from multiple columns and put the data into one column. Additionally, I do not want to exclude any data (union all) and I would like to group the resulting union by another field. For example:
Original data layout:
Column Headings: Sample Event, Depth 1, Depth 2, Depth 3,
1st Row Data: 1, 6, 9, 12, 9
2nd Row Data: 2, 7, 9, 8, 3
Desired data layout:
Column Headings: Sample Event, Depths
1, 6
1, 9
1,12
1, 9
2, 7
2, 9
2, 8
2, 3
So far I'm using the following SQL. What do I need to add or change to get my desired result of grouping the unioned depths by the 'sample event' field?
I appreciate any help anyone may have to offer. Thank you.
SELECT Depth1 AS Depths
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth2
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth3
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth4
FROM Depth_Velocity_Substrate_Correct
Union all
SELECT Depth5
FROM Depth_Velocity_Substrate_Correct

I have a field called density which needs to be updated to show either 10, 20, 30, 40, 50,60, 70 or 80 depending on a number of variables, for example: If market location is 'hot' and unit type is 'house' and discounted is 'no' then show '10' in the density box.
or perhaps:
If market location is 'cold' and unit type is 'apartment' and discounted is 'no' then show '20' in the density box.
I have tried all sorts of expressions and queries but have really reached the limit of my know how and can't solve it. Is it even possible to do this in Access?

-the user will fill only the columns (File Type - Source - Delivery)
-the column (Return) will be filled automatically if (Delivery) not null

I am working on a database which has two tables used as part of a registration and login process.
I would like a couple of fields from table one to automatically update in table two, once the fields in table one are populated without using an 'on click' event.
The reason I would prefer not to use an onclick is because the completion of the form used to generate the users table does not require any buttons for the data to save.
