Create A New Table Ignoring Dupes
Jul 18, 2006
MS Access 2000
I have 2 tables “MDW” and “LeadList”
Each table contains the same type of data (Contact information)
Some duplicate records MAY be in both tables.. (I would like to ignore the dupes).
Each table has a unique ID field but are in no way related
I need to create a 3rd table “NewTable” WHERE…
MDW!FirstName is not = to LeadList!FirstName
And
MDW!LastName is not equal to LeadList!LName
And
…….. I need to look at 10 fields
My thought was to create a query with both tables. Create Joins (where both are equal) for all 10 fields and moving on from there. The fields may or may not have values. I don't think I could add records if only of the indexed fields are null... Can I?
Does anybody see me walking in front of a freight train? Or, any other ideas?
TIA

I have a database where my indexed field in my table is a number set up like this (ex, 1111-0108) where the first 4 numbers are the record # (so can't dupe) and the second 4 are the month and year. Of course the whole field is indexed with no dupes but changing the first 4 provides the change.
Right now we enter manually when starting a new record in a form. Is it possible to auto populate the new record with the next number in the sequence for the first 4 digits and the current month and year for the second 4? If not, is it possible to auto populate it with the next number in the sequence for the first 4 and leave the next 4 blank?
I'm a noob as far as programming goes, however I built the database so I have a "fair" understanding of access.
Thanks,
Dave

I am creating a small Access application that will allow me to update my Call handling system's site table.
It uses an mdb file, and I wish to add new sites (from new contracts) to the SCSite table.
I recieve regular updates of new sites from existing customers, so want to create a simple macro that will
1: import (from an excel file) the new sites and add these to the existing SCSite table
2: Check for duplicate records using the Site_Num primary key
3: Merge non duplicate records into existing SCSite table.
Is this possible, and if so - how? VBA? Macro builder? Query?
A Swift response would be great, I have had a look through previous posts - but to no avail!

I'm trying to create a combo box that takes its values from a field in a table, the thing is that this field has duplicates because:
* The table is a qualification look up table
* It has 3 fields: QualificationID (autonumber), Qualification(e.g. Bachelor), Programme (e.g. Science)
* E.g of duplicate values (this is not a problem as it is necessary) Bachelor of Science, Diploma of Science, Certificate of Science
What I'm trying to do is create 2 single-columned combo boxes that are a parameter for a query and it's working except the combo boxes show duplicated valuesIs there a way to get the query that is the row source for the combo box to eliminate duplicates?

I have a table of plant names such as
×Mahoberberis
+Crataegomespilus
Iris
Scilla
Hebe
Geranium
Acorus
Note that the multiplication and plus signs are part of the names.
If I sort the table (A-Z) I get
+Crataegomespilus
×Mahoberberis
Acorus
Geranium
Hebe
Iris
Scilla
What I would like to see is
Acorus
+Crataegomespilus
Geranium
Hebe
Iris
×Mahoberberis
Scilla
I am not a programmer so need to be led by the hand, but can anyone see a way of achieving this which I could copy? My simple mind tells me that I have somehow to suppress the × and + during the sort. But how?

When running a search I would like Access to ignore international characters like á é í ó ú ñ.
For example searching for "Amelia" matches both "Amelia" and "Amélia"
I know this is done in SQL Server by setting it to ignore nonspacing characters.
Can this be done in MS Access?

I've been using the following query:
SELECT
[qry_1].Month,
B_Division_Group.Grouping_Name,
Sum([qry_1].Month_Client_Count_from_B) AS Monthly_Count,
Sum([qry_1].Month_Assets_from_B) AS Monthly_Total,
Sum([qry_1].YTD_Client_Count_from_B) AS Yearly_Count,
Sum([qry_1].YTD_Assets_from_B) AS Yearly_Total
FROM
([qry_1] INNER JOIN tbl_branch
ON [qry_1].BranchCode = tbl_branch.BranchID)
INNER JOIN B_Division_Group
ON tbl_branch.BranchName = BDivision_Group.N_Br
GROUP BY
[qry_1].Month,
B_Division_Group.Grouping_Name;
While all monthly and yearly values were positive, the query produced exactly the results expected (i.e. one row of data for each Grouping Name/Month combination, containing the overall totals for each field).
Now, however, some Grouping Names have minus values and the query is showing an extra row (one for positive values, one for negative). It's as if having one or more minus values is being treated as a new Grouping Name/Month combination.
Is Sum() the correct method to use, when dealing with negative values, or should I be using some other function?

:confused: I have a Text box on a Form that copies data entered into other Text boxes on the same form.
Sometimes there may be the odd text box that does not have any data in it.
Is there anyway that I can put in code so that the blank text boxes are not copied into the main text box i.e. Only the populated text boxes are to be copied.
Thankyou for any assistance that you can provide.:eek:

I am currently importing data using the the "TransferText" method in Visual Basic; e.g., expression.TransferText(TransferType, SpecificationName, TableName, FileName, HasFieldNames, HTMLTableName, CodePage)
Per the above description, I can either include the first line as a field name, or as data. Is there any way to simply ignore this data row and start the import from row 2 onwards?
Thanks as always

I am currently trying to import a text file into an Access (2000) Table. My text file has a header line (first record) and a footer line (last record) which I want to ignore when importing. I am sure someone out there would have had a need to do something similar to this in the past. I am wondering if someone can point me in the right direction.
I have tried a few different google searches and nothing promising seems to come back. Mostly just references to check the first line for field headings box.
Any assistance would be appreciated.

I have a db with two tables linked by a Set_ID field. One table characterizes set information (date, time, location etc) and the other table has records for groups of fish caught in the set. The fish_table has (amongt others) a field for species (text), clip-status (yes/no), coded wire tag status (yes/no), and 'count' (number). The count field is necessary to allow input of groups of fish en-masse, or individually, depending on the amount of accessory information obtained.
Obviously, some sets catch no fish and so no record is entered into the fish table for those sets.
When I design a query, I want to produce a table that sums up the count field for each set, and produces subtotals for each species (and for the 4 variations of the clip/tag status fields).
My efforts so far are only partially succesful in that I can produce the correct subtotals, but only for sets where something was caught. Sets with no corresponding fish_table record are ignored instead of treated as zeroes.
Is it necessary to manually enter a 'zero' count for each species of interest for each set that we do? (Massively time consuming) Or is there some other way to query the db that forces the query to equate no fish record with a zero value?
Any thoughts? I've searched the forum, and googled, but haven't come across anything I could recognise as analogous to my dilema.

In a query, I'm using concatenation to join multiple address fields (organisation, building number, street address, etc) into one field. I'm also inserting line breaks to create a formatted address and then creating a form on the query so the formatted address appears in a text box and can be copied and pasted straight into my label-writer software to print address labels.
This is the concatenation code I'm using:
Expr1: [Organisation] & Chr(13) & Chr(10) & [Building Number] & Chr(13) & Chr(10) etc.
However, one problem with which I am now presented is where a field is blank. E.g. if one of my contacts is retired, then they don't have an organisation listed in the "Organisation" field. This means that a blank line is left between their name and the rest of the address.
When running a mailmerge there is the option of skipping blank fields so that a blank line is not inserted in such cases.
How can I achieve this within the above code?

I have a number of fields that hold values (scores - either 0,1 or 2) that need to be summed but in some cases the value is 99 (which is recognised by our stats program as a N/A type of anwer- This occurs when a question is optional and the user hasnt answered it. I did not want to value to be null (since its not like the user didnt answer it because they missed out on it by accident but rather they could not) and it couldnt be 0 either since 0 actually means something different in the context of the questionnaire.Lets say I have Q1 which has a value of 0, Q2 has a value of 1, Q3 has a value of 99 and Q4 has a value of 2I want to get the total of Q1+Q2+Q3+Q4 for a particular entry but if the value of any or all of the questions are 99 I want access to ignore it and just sum the rest of the values i.e. the sum should read 0+1+2+(99)=3 not 102I want to be able to include this sum function in the expression builder if possible since I am using it for a report. Can someone please help?

I'm using the Date()-1 to populate a form with yesterday's date for easier data entry. However, on Mondays I always have to change the date to Friday's date because it is populating yesterday's date (which in this case is Sunday). Is there an access expression that calculate yesterday's date but ignores weekends? So that on Monday yesterday would mean Friday?

I have a form with 4 different search fields used to query a table and limit results: Policy#, SSN, Credit_Amt, Debit_Amt. Any matching rows based on the search criteria are returned in a subform.
My problem is how to handle any fields where the user doesn't specify a search value.
In my query, I have the Criteria set to:
Field: Policy_No
Criteria: =[Forms]![form name]![Policy#]
Field: SSN
Criteria: =[Forms]![form name]![SSN]
and so on....
If I place my criteria on different OR lines, the query runs, but if a user specifies more than 1 criteria, I get all the data for one criteria(such as policy# matches) and all the data for the second criteria(such as all the records for a certain credit_amt, regardless of Policy #).
If I place my criteria on the same criteria line, effectively making it AND, I get no results because I assume the database is looking for any blank search field values.
So, how do I make the query an "AND" query, but actually get results by ignoring any NULL search fields? So if a user enters a Policy# and Credit_Amt, the results will be only matching rows by Policy# AND Credit_Amt, and doesn't look at SSN and Debit_Amt.
I've tried different iterations using IIF(Not IsNull(.... to no avail.
Thanks!

Hi everyone,
I have 2 linked tables from 2 different databases, there is a common field in both: “CORP_NBR” I need this field in order to create a join, but the problem is that in one table this field stores leading zeros and in the other table it doesn’t. I can see in design view that this field is text type in both tables. I cannot change field types because I don’t own the objects.
Is there a way or a function that I can add in my join query to ignore leading zeros? :confused:
I appreciate your help

Access 2013 on a Window 8.1 system.
I have a combo box based on a look-up table which I use to filter the records in the form. Seems after closing the form and reopening it, the filter remains.
I'm not sure if this is referred to filtering or restricting the records.
The value in the record source doesn't get changed but the records displayed don't reflect this. The records shown are the last filter I selected in the combo box.
The only work around I have found is I must explicitly set the record source in the on open of the form.
The was not occurring with access 2010. And I have made no changes what-so-ever.

I have a form, frmProjects, with a continuous subform, sfrPeopleOnThisProject. They have a master-child relationship. The form shows one Project record at a time, while the subform shows all the People records for that project. This works as expected - the correct records show up in the subform as you move through the form records.
To make it easier to glance through the list of subform records (as they can sometimes be quite long), I've added a navigation combobox to the header of the subform. If I understand correctly, as the combobox is within the subform, it should obey the master-child relationship: it should only show the subform records associated with the main form's current record. It does not. Instead, the combo box collects *all* of the records from the table that the subform is based on. So, choose the record for Project 1 in the main form. Up pops the 2 people on Project 1, but the combo box lists both the 2 people on Project 1 and the 3 people on Project 2.
The row source for the subform combo box is:
SELECT tblPersonOnProject.PersonOnProjectID, tblPerson.Fullname FROM tblPersonOnProject INNER JOIN tblPerson ON tblPersonOnProject.PersonFK=tblPerson.PersonID ORDER BY Fullname;
I can make the combo box perform as required by adding "WHERE Project=Forms!frmProject!ProjectID" to the row source and placing a hidden textbox on the main form for ProjectID (the autogenerated primary key) to sit. Have I misunderstood the point of the master-child relationship in the subform? This hidden textbox thing can't be correct.

I have a make-table query that pulls all the fields from 1 table (MainTable), and creates a new table with a date stamp based apon a form value entered (New Table = MainTableWithDate).
Currently, I setup the query to pull info from the form field like this:
DateField: [Forms]![frmmain]![DateField]
However, when the make-table query is done - all date fields are blank (all other fields are correctly created), and when I look at the new created table (mainTableWIthDate), the typeassigned to the date field is "Binary" (in the form, I've specified LongDate).

I have three tables that contain different columns but linked by a primary column call Name. I want to create a table where all these different columns in the three tables join to form a master table which can be updated regularly either through the master table or the smaller tables. The master table also has the primary column as Name.
If I update the master table with records, it should update the respective linked table and vice versa. I also want to link these tables to my SharePoint site.
Note: except the Name column, none of these tables have any other columns in common How do I go about this?

Here is what I am trying to do: I have form, and a table which is created from this form. The data is entered a second time using the form to make sure there are no discrepancies.

I have two tables. The first one is as follows:
MP No (Primary key), Sales, Date Entry, Specs, Email
The second Table is as follows:
MP No, Quantity, Description, DWG, Price
There is a "one-to-many" relationship between the two tables through the MP No field so whenever I go to the first table there is a sub-table for each MP No. Correct?can I create an extra sub table under the sub table already created?

I'm a relative newbie to the more advanced features available to Access.
If someone could help me or point me in the right direction, I'd really appreciate it.
I have one table that contains companies and associated contact info. Each company can have more than one unique number ID (3 digit alphanumeric).
I want to take this table and run a query to create a new table that will only have one instance of each company name, along with the other contact information. The unique ID's aren't needed in this table (but it would be great if I could somehow toss them in, too).
This new table would then be used to create a form with a combo box containing all of the names to quickly jump to their contact info.
Any and all help would be appreciated. If a query isn't the best avenue for this, then please point me in that direction, too.
Thanks!

Hi there :)
I'm not sure if I've picked the right forum topic for this... It's not a straightforward table question, and I think the only way I can do what I need is with a query of some sort. Apologies if it should have gone in 'Tables'...
The situation is: I'm creating a database (using Access 2003) in which our secretaries can enter exam marks for students. The difficulty is that there are ten papers (exams), each student's exam is marked by at least two examiners and there are at least 6 examiners per paper. Every examiner also marks more than one paper, but doesn't mark all papers.
So, I've got a table with all of the examiners and the papers they're marking and I've got a table with all the students and the papers they're taking. Because we have to enter the marks in such a way that we know both which mark an examiner gave and (obviously) which mark a student received (e.g. so we can look at statistics for each examiner), I thought the best way to do this would be to run a query that created a new table per paper in which the field names would be: Student_ID, <name of examiner 1 for the paper>, <name of examiner 2 for the paper>, <name of examiner 3 for the paper>, etc until the end of the list of examiners for that paper. The student's number would populate the Student_ID field and then the secretaries would enter each examiner's mark in their named field. Like this:
| Student_ID | A.N. Other | J. Blogs | J.Q. Public | Agreed_Mark |
1234A 72 74 73
2345B 65 68 67
3456C 71 73 72
4567D 52 51 52
Listing the name of every examiner (including those who aren't marking that particular paper) isn't an option (and would have to be hard coded into a table in any case, as far as I'm aware, either in a query or in a table design. This is something I'm loathe to do). Ideally, the secretary would be able to press a button on a form and have all the mark entry tables for all the papers created automagically.
The examiners for the different papers change every year, and not every academic marks exams every year, so this data will not remain static. Hard coding a table with examiner names would make more work for the secretaries. (I want to avoid this as all mark entering for all students is done in a single day. This means over 600 students at 3 marks per student [mark 1, mark 2, and final agreed mark] with time to contact examiners with questions... and only 2 secretaries, each of whom deals with a different section of students).
Because of the nature of the marking, it would also make quite a lot of work for the secretaries if we had to cross reference a generic Examiner_1 field with a different examiner for each paper, so the field name really must be the examiner's actual name.
Can anyone help me? I'm happy to do it with either VB or SQL; I'm not a programmer, but I can usually work out what code does even if I can't write it myself. I should be able to adapt anything presented as long as it's complete and doesn't assume that I know the basics. :) I've also got two reference books to hand: _Microsoft Access 2003 Forms, Reports and Queries_ by Paul McFedries and _How to Do Everything with Microsoft Office Access 2003_ by Virginia Anderson.
Thanks very much for your time. :)
