Queries :: Comparing Data Differences Between Two Identical Access Tables?
Dec 10, 2013
I have two identical Access tables, for example tblDataYesterday and tblDataToday. The data from tblDataToday has updated data changes in it that are different from tblDataYesterday. I have a maximum of 100 fields to review. I want to compare the two tables and display in a query the differences between the data from both tables.
Hello, I have 2 fields that are supposed to have the same information for each record. I got the information from different sources, which is the reason for having 2 fields. I wanted to make sure that the information was accurate. Turns out, that some of it isn't accurate--all the fields don't match.
As you can see, the ISSN numbers for Title 1 and 3 match. There's no problem there. I want a query that would list all those like Title 2, where the ISSN numbers don't match. Then I'd have a list of all of the problem Titles, and I could look up the real ISSN numbers.
I have a form control with the input mask on it for a phone number. I am using an append query to append the information entered in the form to a table. I need to pull two fields from a linked table from another database. What I need to do is be able to compare the entered phone number in the form with the phone number from the table. The problem I am running into is that it won't match the phone numbers. The same mask is used in the table I am pulling from. Why can I not just put =[Table].[Phone_No] in the Criteria of the field where the number from the form is placed so that I can get the right record from the linked table?
I have multiple databases (one for each department). All 4 databases have an Agents table (tblAgents). Now I am creating another database that uses all of the agents on site. What I want to do is link all the agents tables and combine the values in one query.
The tables are linked to my new database. So logically, I'd think my next step is to query the tables. This is where I'm stuck. How do I say:
Agent = tblAgentsDepartment1.AgentName and also tblAgentsDepartment2.AgentName and also tblAgentsDepartment3.AgentName and also tblAgentsDepartment4.AgentName?
I have a question regarding making a query with joint data that are not identical, as I'm not sure whether it's possible.
I have to look at certain serum levels at te start of a new medication regimen, and serum levels after 5 years.
I have one database with:
Patient number Start date medication Start date medication + 5 years And one database with:Patient number Date of blood test Serum level molecule A Serum level molecule B
What I want to do is make a query where the patient numbers are joined. The problem is that the "start date of the medication" and the "start date + 5 years" are not identical to the dates of the blood tests. E.g.: I have a patient that started medication on 01/March/2006, but he has had blood tests done every 3 months from 28/November/2003 till now, and not on 01/March/2006.
I would need the results of the blood tests (of molecule A and B) at the start of the medication and after 5 years, but if the test date differs by a day, Access already sees they're not identical.
I would like to have access select a blood test date that is as close to the medication start date as possible, within a time frame of e.g. +3 and -3 months. Is this at all possible?
...TableA: 1 indexed field "Name" and many data fields in ~ 1000 records ...TableB: 1 indexed field "Name" and 2 data fields (DataB1 and DataB2) in about ~ 50 records
Tables currently have NO relationship set.
Want to add TableB data fields to TableA if Name are identical.
DataB1 and DataB2 fields are Not currently in TableA but could be added very easily.
Update (or whatever) will be done weekly where all previous data for DataB1 and DataB2 will be cleared from TableA before job is run.
Hi guys, i'll try and explain this as best i can....
I have 2 tables:
CurrentMonth PreviousMonth
Both tables hold financial information by policy number. What i am doing is working out financial movement on a month on month basis. For example, if in previous month the financial position was £100 but in current month the finances had moved to £150 then the movement is £50 for the month. This i can do no problem by linking the tables by policy number and extracting the financial position and subtracting one from the other to give me a movement. However, in some instances there will be some policies that appeared in PreviousMonth but have since been cancelled back to policy inception so is not appearing in CurrentMonth.
Problem: I need to be able to bring in the policies on the previous month that are not appearing on the current month (due to cancellation).
I have 2 tables. Quotation Details and Order Details. As you fill in the Order details Form I wish to compare fields from the Quotation Details Table. Is this possible? Please advise. Thank you.
I have got 2 access tables named Table1 and Table2. There is one field common in both the tables and that is "Reference" . So I need to match the data in Reference field in both the tables using VBA.
steps to perform:
1. Check each Reference in Table1 against all the values in "Reference" field of Table2.
2. if match occurs then store all the details of that Reference in Table3.
There could be more than 1 match of that Reference in Table 2 and we need to check the whole Table2 for each "reference" value in "table1".
As a Access newbie I am looking into a problem that I hope to solve structurally and "transparently" via Access in stead of Excel.
I would like to compare two similar tables for different months. I am looking for:
+ loan id's that are new in table(t), i.e. not exist in table(t-1) + loan id's that exited: that is exist in table(t-1) and not in table(t) + loan id's that stayed in both
We have an "item" table that contains information specific to an item (the item number is unique); and multiple "production line" tables. There is a relationship between the Items table and the Production Line tables (all 8 of them). Each item can be entered on 1 or more production line tables because one item may be produced on multiple lines and the settings vary based on the line they're produced. When entering an item in the Production table we MUST make a selection from the Item table.
Now, what I want to do is identify which item number(s) from the Items table does not have a specific field entry in ANY of the Production Line tables.
I have 2 tables one Access, one FoxPro both containing similar information. The idea of my query is to compare both tables and update the Access table if the value in the FoxPro table has changed. This works fine for a number of similar queries that I have. However, intermittently, this query will see two values as different when they are exactly the same and replace the value in the Access table with a seemingly random value. I know the "Random" values are from other records within the table but cannot see any link between the values.
I have a table which is used to record electric billing period dates, total kWh and costs for a list of locations each month. I would like to compare the quarter total kWh and costs for this year "2013" against same quarter last year "2012". I have created two queries, the 1st is capturing data from 2013 and the 2nd is capturing data from 2012. I created a 3rd query which joins the 1st and 2nd together by month where fields match. Both tables have the same fields, however there is more records in 2012 than 2013. How can I join the tables together so months that have no data are left blank?
I have a simple (I hope :) ) question. I have two tables in my database. Tables are simple and the structure is the same Tables contain some different and some the same records I want to create a new table (or Raport maybe) which contains differences (different records which are not in both tables) How can it be done in the easy way?
Sorry for such stupid question but I have tried to find this forum for similar issue with the easy solution but no luck.
I have a Table named WorkUnit1234567-01-01-07. We'll say the info on this table is from 1 January. I will then have a Table named WorkUnit1234567-02-01-07. We'll say the info on this table is from 1 February. Both of these tables will have the same fields. What I would like to do is compare Table WorkUnit1234567-01-01-07 with WorkUnit1234567-02-01-07 and only show the differences between the first table and the last table. Any ides on how to accomplish this?
I am using ACCESS to compare roles for users on our SAP system before and after a QAS refresh. I have two tables, one listing roles before and one listing roles after the refresh, how do I have to relate these two tables and what type of query should I run to present me with a list of roles that appear in one table and not the other, since I have two tables there may be roles in table a that arent in table b, as well as roles in table b that arent in table a. I need to see both these. I also dont want to see any roles that appear in both tables.
Basically I would like to populate column three "OUTCOME" according to the following logic:
if train A10 has multiple destinations (we see this in the second column) then in outcome I woudl like to have "multiple destinations" if the destination is only one (in case of trains A15 and A16) , then I would like to have that city in column 3 "OUTCOME".
I need to combine two tables that have identical structure to one table. Different people have used them to insert data from different parts of our project. I have tried to find information about how to do this but so far with little luck.
I'm just wondering if there is any differences in writing queries in vba in different versions of access. i'm developing a search function in access 2000, but it doesn't seem to be working. however, the same code in access 2003 works fine.
Here's an extract of the code when the search button is clicked (I'm getting table information, attribute/field information and condition they're specifying from the user. The result is then displayed in a subform):
Private Sub cmdFind_Click() Dim searchSQL As String
The part in red is the part that is highlighted whenever i run it in access 2000. The error message is: " You entered an experession that has an invalid reference to the property RecordSource "
Can anyone tell my why it's like that and how i can fix it to work for access 2000?
Thanks I've also enclosed a picture of the form, so you can get a feel of what it looks like.
I have an Access DB built that links to an excel spreadsheet. The spreadsheet changes so I cannot import and have to link.
Now the source of my spreadsheets is producing two spreadsheets with identical fields but different data. I need to combine the data from these two spreadsheets. Can I link them both and combine them in a query? How?
I am trying to count how many of the "same" and "differences", as well as calculate the percentages of the number of "same" over the total amount. To clarify, I work at a nursing home, and I need to calculate the number of people who were admitted to our facility and then to the hospital for the same diagnosis, and a different diagnosis. Then, out of the total number of people who were admitted to the hospital from our facility, I need to calculate how many of those people had the same diagnosis or a different diagnosis.
Also, I need to categorize these diagnosis by each type of diagnosis.
