Matching Fields
Jun 19, 2007
Hi All,
Wondering if you can help I have a table called "example" which has field "a" "b" "c" "d"...
I then create another table called "importtable" with field "a" (imported in from Excel)...
I would then like to create a query which matches any and shows all the records which I imported in from Excel to my current table called "example" I looked at joining via "relationships" using a Select Query but it doesn't quite show what I'm after...
Should add I would like Field "a" in both tables to show but only if the number exists in the "importtable" if not then don't show..
Any tips :confused:

In a database I have two tables, one is linked to an excel sheet (our customers order) and the other is created via a "make-table query" from our business system.
In both tables I have the customers part numbers and neither contain a primary key.
What I need to do is compare the part numbers in both tables to find if a part number is present in the order but not in our business system.
I just cannot figure out how to do this.
Any ideas are greatly appreciated

Hello,
I have a few tables containing different exam data for students - and a unique identifier with each. I need to add another unique identifier (which is already specified from another system).
Now, can I use the existing identifier (UPN) to automatically put in the new identifier into a new field (AdNo).
If that makes any sense at all, I will be surprised...thank you!

I have a series of numbers in 30 columns. I want to identify where either of two numbers appear in the same record regardless of which of the 30 columns they are in.
OTHCPT2OTHCPT3OTHCPT4OTHCPT5OTHCPT6OTHCPT7
00300C1778C1820J0690 J2250 J2270
00300C1778C1820J0690 J2250 J2270
00300C1778C1820J0690 #NULL!#NULL!
2318095978C176788307J0131 J2270
For instance if 23180 and J2270 are in the same record I want to identify them for all of the records.

For my query I have 3 tables.
TEAMS. This contains TeamID / TeamName and TeamManagerName.
TeamAPPLinks. This is a many to many relationship and contains TeamAppID / AppID and TeamID (TeamID links to Teams.TeamID and AppID links to Applications/AppIS)
Applications. This contains AppID / AppName / Pass/Fail.
So teams can have many applications and applications can have many teams.
I only want to show teams that have all applications that have the Pass/Fail column as PASS. I have managed to do this for FAIL runing a query in a query but obviously its different for PASS as all associated applications have to be a PASS, not just one FAIL for a FAIL.

How to get the following results using 1 table:
Field1 ID is an auto record ID, field2 ID is actually field1 ID assigned that record, in other words record 1 has a roommate (record 5) assigned to it, record 2 has a roommate (record 4) assigned to it
Table A
Field1 ID Field2 ID
1 5
2 4
3 6
4 2
5 1
6 8
Results records I'm looking to display for would be:
1 5
2 4
3 6
6 8
I only want to display all fields for records, but I don't want to show their matching record, so I want to display record1, but not record 5 because record 1 has record 5 as a roommate, want to display record 2 but not record 4.

I am undertaking an analysis of corporate mobile phone data based on data from the phone provider. The base data consists of a number of monthly text files at transaction level for voice calls, data usage, billing/tariff information, international calls/transfers etc. I have set up VBA code to import the text file data into a number of Access tables.I would like to have a way of joining these tables but the only common field is the phone number (a text field with the groups of numbers separated by hyphens).
I confirmed that joining the tables on the phone number text field does not work.My idea was to create an additional table with just one row for each phone number and link that to the other tables by the ID in the new table. I was able to create this table [PhoneNumbers] (by creating a totals query of the phone numbers from the main call transactions table, I then dumped it into Excel and then imported it into a new Access table with an auto-generated ID column).My problem / challenge is how to get the ID column from my [PhoneNumbers] table to appear in each of the other tables so that I can join them effectively. In the Excel-world, I would have used a vlookup function.I even thought of performing this as an interim step in Excel but there are too many records / rows in some of my tables. It seems that the dlookup function is not what Im looking for and even if the IIF function is suitable, I cannot get the syntax to work for me.

I'm trying to clean up a database and make sure that I don't make an error in future entrys.
Is it possible to make a "key" that highlights the rows with matching keys. The thing is that a the "key" is Switchname + Switchport, data placed in 2 different columns in the same row.
How do I do this? Is it possible?

The table ProductInfo has an ItemID, and its corresponding Quantity.The table Orders has a PO column, an Item# column, a OrderQuantity column, and the column Item#CurrentStock which holds the Quantity of the selected item, for 3 items.I have created a form that has a ComboBox populated with the ItemID's from ProductInfo, that when selected populate the corresponding Item# in the Orders table.
I would love if the Quantity(stock) from ProductInfo would automatically fill the Item#CurrentStock field on the form when the ItemID is selected from the ComboBox.But all of the fields only relate to Item# from the first ComboBox!?!?I have tried =dlookup,

I have two databases (files). Each file has a format like the one below.
File 1:
chr start end
chr1 1000 2000
chr2 3000 4000
File 2:
chr start end
chr1 1500 3000
chr2 3750 4000
I want to be able to merge the two records together if the field chr matches between the two files plus if there is an overlap between the start number and end number from each file. For instance the first record from each file would match because the range from 1000 to 2000 of file 1 has numbers consisting of 500 numbers (1500-2000) that are also present and overlap in file 2 (1500-3000). I possibly cannot use < or > since the ranges from each file will vary to different degrees. Perhaps there is a between function that might work...

I have a table tROE with a field listing all dates starting 1/1/10 to date (populated), and three fields for currency exchange rates [USD], [RSD] & [EUR] which are empty and need to be populated. I have another table tROEPartial that has the exchange rates for some of the dates starting 1/1/10 but not all. Their structures are identical. I want to add the exchange rates from tROEPartial to tROE where the dates match, leaving the unmatched fields in tROE blank.

I'm trying to make it a little further with my new call answering database at work.
Basically it consists of a main form that has a button leading to a call answering form for each business that we represent. it also has a text box that displays the number of the caller when the telephone picks up, the correct call answering screen is also popped by the telephone software and a macro whenever the phone is answered.
I've got code in place that automatically puts the date and time in the correct field and also copy the incoming telephone number from the main form into the caller number field on the call answering form.
I'd like to take this automation a little further now and get the form to autopopulate the caller details if that caller has called before (we get a lot of calls from the same people) so i'd like to make the form search the table it's linked to for the incoming phone number and to fill in the name, email, company etc... for the caller according to the previous record.
The code for the 2 forms i've currently got setup (the switchboard and one call answering screen) are as follows
Switchboard:-
Code:
Option Compare Database
Dim WithEvents MaxxCom As Metro_MaxxCom_CTI_COM_API.CTI
Private Sub cmd_onnet_Click()
DoCmd.OpenForm FormName:="On_Net_Communications"
End Sub
[Code] .....

I have a subform in which I want to put in a Command Button to open another form.
I used the wizard as per normal, but when you come to matching specific data fields, there is nothing in my left hand column of the sub form. I have checked the record source property and it is bound to the correct table.
I have read that this is an issue with Access 2007? Is this the case or am I missing something obvious here?

Hello eveyone . . .
i am attempting to create a VERY complicated query . . . it's sort of confusing:
I recieve data from an outside source and it is up to us to format it for our own analysis . . .
i have fields:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
The fields we want to focus on is "AccNo" and "TestCode"
Now i want to filter based on this condition:
If "AccNo" AND "TestCode" BOTH have duplicate data in a record. Show that record only once. Remember. . . "AccNo and TestCode, both these fields have to have duplicate data in a record.
Example:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
CAPT.....M566679.....John Blue.....123456.....CBCA
CAPT.....M566679.....John Blue.....123456.....CBCA
the example above should only display once because of the repeated AccNo and TestCode
Example:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
CAPT.....M566679.....John Blue.....123456..... CBCA
CAPT.....M566679.....John Blue.....123456..... LIPID
the example above is just fine because the TestCode is not matching
How do i create a query to accomplish this? someone please help, i've had troube with this for the passed couple weeks . .. .

Hello All,
For those who are interested in Approximate String Matching or those who could use these algorithms; I have a complete suite of Approximate String Matching algorithms written in Visual Basic in an Access database.
In 2004 I decided to jump into the world of Fuzzy Matching with both feet.
As it is, I am working for a company that deals with names, addresses, etc. very intensely. It is a fair sized company that
uses Access on a grand scale. Since I am an Access programmer, I work in an Access gold mine!
I knew that if I could get a good handle on Fuzzy Matching, that when I hit the right person at the right time, the company could greatly benefit from my research on Fuzzy Matching. The right time and the right person are not here yet.
Nevertheless, since I have reaped much free source code and information from the Web, it is now time to return the favor.
I developed a package that is sort of a demo/tutorial on Approximate String Matching algorithms in Access that is very
robust in Fuzzy Matching. It would overtax the post in this forum for me to include it in a post.
To summarize, it works with the basic name - Last, First, and Middle. It has a user interface that allows a user to type in
what would be a good name and what would be a questionable name to resemble the good name. The weighted results of all the various algorithms can be chosen, or an individual algorithm can be chosen to display how closely the names match.
In addition, it has a table of 17,295 known good names with unique ID numbers as a reference table, and table of 1200
morphed names that are typical of names entered in a database with no input conventions. These morphed names have typos, transpositions, variations on maiden names, etc. 1200 good names were selected for alteration and the unique ID of each original good name was stored in the table with the altered names to determine the accuracy of the matching process.
The morphed names were compared to the known good names in a query with an approximate join using the suite of algorithms to determine match percentage. The altered names, the ID number of the original good name, the ID number of the name it matched to, and the match percentage were stored in a results table to determine the results of the matching run.
These tables were used to test and tweak the algorithms by comparing the morphed names with the known good names. The results of 1322 names were saved to a results table with match scores.
The matching process was executed in a query with an approximate join using the suite of algorithms.
The match results:
Total Approximate Matches: 1188
(Recall) Precision Pct: 99.00%
Total Unmatched Names: 12
Unmatched Pct: 1.00%
Total Other Matches: 134
Other Matches Pct: .77%
The tables are accessible in the database, so anyone can run their own tests. The interface is set up to accommodate this
as well.
The algorithms used: Dice coefficient as a threshold algorithm, Levenshtein Distance algorithm, Longest Common Subsequence, and the DoubleMetaphone. The names were passed to the algorithms by way of the bigram model.
I will email it to anyone who requests it.
It is in two platforms, Office 97 and Office 2000 as FuzzyMatching97.zip (692 KB) and FuzzyMatching2k.zip (721 KB).
The zip files include ApprxStrMatchingEngine97.pps or ApprxStrMatchingEngine2k.pps respectively, StrMatching97.mde or StrMatching2k.mde respectively, IEEESoundexV5.pdf, and VBAlgorithms.txt.
IEEESoundexV5.pdf is an abstract about Approximate Sting Matching that fired my curiosity about the subject, and pertains to the package.
VBAlgorithms.txt contains the entire suite of algorithms in Visual Basic extracted from the MDB modules.
The PowerPoint presentations describe the workings of the MDE and give a good overview of Fuzzy Matching.
To match is divine....

A very elementary question - but I'd be grateful for an answer.
I have two tables (or perhaps two queries) each with a key field. If all is well, there should be complete correspondence between the two sets of records. That is, if there's a record with key 12345 in one table, there should also be a record with key 12345 in the other table.
I'm looking for the simplest way of checking whether or not this is the case, and, if it's not, detecting which records in one table are unmatched by any record in the other.

Hello,
I am using this query to get matching data:
SELECT NewMyEstartChild.yordob, NewMyEstartChild.firstname, NewMyEstartChild.surname, NewMyEstartChild.postcode
FROM NewMyEstartChild INNER JOIN For2003 ON (NewMyEstartChild.postcode = For2003.POSTCODE) AND (NewMyEstartChild.yordob = For2003.MyDOB);
but It's giving me more data so to minimise data I was thinking to add another filed. which is Firstname field. but some children's name are spell incorrectly.
How can I match data with first letter only ? I have tries following query but it doesn't work. Please help!!!!!!!!
SELECT NewMyEstartChild.yordob, NewMyEstartChild.firstname, NewMyEstartChild.surname, NewMyEstartChild.postcode
FROM NewMyEstartChild INNER JOIN For2003 ON (NewMyEstartChild.postcode = For2003.POSTCODE) AND (NewMyEstartChild.yordob = For2003.MyDOB) AND (NewMyEstartChild.Firstname = For2003.Firstname);
In last part of this query (NewMyEstartChild.Firstname = For2003.Firstname); How can I get the name of children whose firstname's letter is similar.
Thank you

My problem is this:
I have a large table with about (8000+) records and a smaller table (2000+) records.
The large table has been exported from an ACT! database.
The smaller table has 4 fields that i need to add to the larger table, and then i need to import the updated records back into the Act! database.
I created a simple select query and matched the tables with the only 2 criteria that match the 2 tables, this was "Company" and "PostCode".
This should have been ok, but instead of updating 2000+ records it only updated 1000. The reason for this is because some of the company names weren’t an exact match, "company ltd" and "company limited" etc.
If i just linked "postcode" to "postcode" there are quite a few different companies that have the same postcode.
Is there a way of trying to match just the first 5 characters of the company name but leaving the "company" field intact?
Or is there a different way to go about this?
Thanks
Darren

Im trying to work something out on Access at the moment to score some brownie points with my boss and am hoping someone will be able to help me. Im relatively confident about using access but when it comes to tricky queries i get a bit confused. Basically my situation is that i need to do some matching. Using a PO number and a unique ID and updating a column in one of my files with the unique ID. I have done it this way so far....
Linked the the two files together and matched them on the PO number and then updated the field with the ID where they matched. This seems to work ok, but the problem is that about 10 of the PO numbers contain between 2 to 6 different ID's. Therefor how can i make it so that if there is a PO number 6 times in the file it will match with all the ID's. I dont think that this is to hard to do, but each line has a different cost and they have to be matched to the write one. The problem with this is the cost is normally different as it flucuates with the exchange rate. I can only think that the best way to do this is to use a function that looks at the cost and if its say $20.00 more or less then assume its that. But have no idea how to implement it.
Does that make sense? Is it likely that its going to be easy to do. Im relatively ok with SQL if it would be easier to use that.
If anyone has any suggestions it would be greatly appreciated...
Thanks :)

I have two tables that have fields set to a text so that the ClientID is their name.
When I query, my queries don't take into account the case. So "K Smith" is the same as "K SMITH" as "k sMIth"
I am trying to write an unmatched query between two tables based on this ClientID but it will turn up no unmatched because it is not taking into account the case.
Any suggestions on how to match the cases, othere then changing the table?
Thanks.

Hi. I am in the process of loading nursing license numbers into my database. The spreadsheet that I am importing from does not use the exact same names as the ones in my database, i.e. Smith, Deb in my database is Smith, Debora in the spreadsheet and I can't figure out the code or procedure to use to tell the database that these names are actually for the same record. Is it possible to do this and if so, how?
Thank you!

Hey all
I have a function to display the opening hours for the next 7 days for a client. I have also included the functionality whereby you can create a "special day" with non - standard opening times which are stored in the database.
I have a simple SQL to check to see if the current day is a special day:
Code:SELECT * FROM SpecialDays WHERE SpecialDate = #" & currentDate & "#"
I have run into this problem tho. There is a special date in the database for 03/01/2007 (UK date format 3rd January) but this is being retrieved for the 1st of March (01/03/2007)
therefore this query:
Code:SELECT * FROM SpecialDays WHERE SpecialDate = #01/03/2007#
retrieves the record with the date 03/01/2007
Any ideas?
Thanks

Many have had questions on how to use this for their own purposes.

Here is how you can use it - I provide this example:
Tables and queries can be created in the MDE database.
Create a table with known good reference strings. I created this one - REF_LIST.
It has one field, REF_STRING (Text) with a length of 50, and indexed (No Duplicates). The field length can be set to a length that suits your requirements.
This is the content:
REF_STRING
Claw Hammer
Cold Chisel
Monkey Wrench
Nail Gun
Create another table with strings to match. I created this one - TEST_LIST.
It has one field, TEST_STRING (Text) with a length of 50, and indexed (Either No Duplicates or Duplicates Ok depending on the data). The field length can be set to a length that suits your requirements.
This is the content:
TEST_STRING
Claw Hamer
Claw Hammr
Clew Hammer
Clw Hammer
Cold Chisil
Cold Chisle
Cold Chissel
Cole Chisel
Monkey Wrnech
Monkie Wrench
Monky Rench
Nail Gn
Nail Gunn
Naill Gun
Nial Gun
Then create another table for the results. I created this one - RESULTS.
It has four fields, REF_STRING (same properties as in table REF_LIST), TEST_STRING (same properties as in table TEST_LIST), MATCH_VALU (Single, Fixed, 2 decimal places), and GOOD_MATCH (True/False).
This is the content from the results of the Match_Lists query.
REF_STRINGTEST_STRINGMATCH_VALUGOOD_MATCH

Monkey WrenchMonky Rench0.94No

Nail GunNaill Gun0.96No
Claw HammerClaw Hamer0.96No
Claw HammerClaw Hammr0.96No
Claw HammerClw Hammer0.96No
Cold ChiselCold Chissel0.97No
SQL from the Match_Lists query:
INSERT INTO RESULTS ( REF_STRING, TEST_STRING, MATCH_VALU )
SELECT REF_LIST.REF_STRING, TEST_LIST.TEST_STRING, IsSimilar([REF_STRING],[TEST_STRING]) AS Expr1
FROM REF_LIST, TEST_LIST
WHERE (((IsSimilar([REF_STRING],[TEST_STRING]))>0.79));
Using this example you can populate the two tables, REF_LIST and TEST_LIST with strings that you need to compare and run the Match_Lists query.
The GOOD_MATCH field in the RESULTS table is for you or another human to determine if anything questionable is a good match for your purposes.
If it is found that any match with a value of at least .95 is a good match then an update query could be created to update the GOOD_MATCH field with true for all those with a value of >= .95.
Then a select query could be created to look at those matches that do not have a GOOD_MATCH to determine if they may be good matches.
Naturally the two tables may need a unique ID for the strings for better tracking and comparing.
If so, create them and have them appended to the RESULTS table as well in the Match_Lists query.
