Queries :: Select Query With Joins Returning Duplicates
Sep 18, 2014
I am building a select query which is grabbing data from multiple tables with items being linked by a unique field "Certificate_ID".
I have created joins between table A and Table B, and Table A and Table C, linking both by Certificate_ID
All have the join property set to select all Records from table A, but only those from Table B and Table C where the joined fields are equal.
Table A has 5000 records. Am I correct to assume that my query should only return a max of 5000 records as well? When I select Certificate_ID from A and another column from B it only gives me the 5000 unique records. When I add in a column from Table C it is however returning something like 7500 records, with several being duplicates with the same data in every column.
Why it is choosing to duplicate records and give me more than I want. I am sure I am overlooking something simple.

My statement below is current returning 4 records. Two of the records have the same GBPAmount value.
RequestID is the Primary Key
Code:
SELECT TOP 3 RequestID, GBPAmount, Currency, RequestDate
FROM PayRequest
WHERE (((Currency)="CAD Canadian Dollar") AND ((RequestDate)>#11/16/2014#))
ORDER BY GBPAmount;
Code:
RequestID GBPAmount Currency RequestDate
10207 8.17 CAD Canadian Dollar 03/02/2015
9874 33.82 CAD Canadian Dollar 20/01/2015
11327 109.58 CAD Canadian Dollar 23/02/2015
10495 109.58 CAD Canadian Dollar 05/02/2015

I am trying to select all projects with the keyword "sett" in them. About a thousand rows with this keyword exist but why isn't my query returning any data? :confused:
Here's an example of the data "STPT-SETT-NY-EQ Legacy"
Now i want to return all rows with "SETT".
What am i doing wrong here please :)
SELECT projectList.*
FROM projectList
WHERE (((projectList.projectName) Like "%SETT%"));
this doesn't work either. No records are returned when query is run:
SELECT projectList.*
FROM projectList
WHERE (((projectList.projectName)="%SETT%"));

Hello, I am sure this is quite simple, however I cannot figure it out. I have a query that shows tblPartNumber and tblAverage. The average is calculated in the query by taking the total minutes to assemble the parts, divided by the number of parts completed. What I am trying to do is run a query that will show me the most efficient (lowest average), time for each Partnumber. Ideally the query would show me something like this;
Part # Average
1234 .72
1234 .86
1234 .94
etc...
I searched on here and it seemed like the Top 10 is used, but in my application that ommits all of the other partnumbers because it only shows ten of the records for the first partnumber. I only want to see the five most efficient averages. Any help is greatly appreciated.
Thanks, Tim

I have a db with 2 tables, one containing basic info FirstName, Surname, YearGroup, and another table with other data. I imported a list of names into the first table, firstname and surname only were imported, other field was left empty, other table was also left empty. I made a simple select query to pull all records from both tables and i get no results at all. None of the imported names show on the query results. what I am missing?

Why is strCreditCheck returning the actual query string and not the result? Of course, this is not working.
Code:

Me.Requery
Dim strCreditCheck As String
Dim strCompany_id As Integer
Dim stlinkCriteria As String

Hi- I have three queries:
Queries: Contain:
qryPrimary - primary_code, 1Reasons, EnteredDateCount as "CountP"
qrySecondary - 2ndary_code, 2Reasons, primary_ref, EnteredDateCount as "CountS"
qryTertiary - tertiary_code, 3Reasons, EnteredDateCount as "CountT", 2ndary_ref
In another query to combine data for a report, I need to see:
All the "1Reasons" and "CountP";
their corresponding Secondary "2Reasons", "CountS";
and finally the Tertiary "3Reasons", and "CountT" that correspond to the Secondary's.
Like a fool I thought it would be easy. I know it is probably a join problem, but I can't figure it out.
Any help would be appreciated. Stevie

Hi, Big Jim here:
I am really not sure where to ask this one.....
My boss and I are in a jam. We have been using Access to run a reporting process, but one of our tables will exceed the maximum fields allotted this month. Our thought, dump the table into SQL Server and use the GUI interface provided in Access Projects.
Unfortunately, the query designer seems to have a few drawbacks. The one that effects us the most is in using UPDATE queries where more than one table is used to determine records to be updated. In attempting it, we get the message: "The designer does not graphically support the Optional FROM clause SQL construct".
Now I know we can manually create Update Queries, but we often need 1,000+ in a short period of time. Manually punching in all the fields involved and other code just isn't timely.
Question: Is there some alternative, service pack or anything else that would allow us to graphically create these Update Queries using Access Projects or even SQL Server 7.0? I would hate to have to scrap all the work we did over something that seems so minor.
Thanks in advance!
Big Jim

I'm fairly new to Access. 's various select queries containing useful and useless results. I want to create a select query that will pick out all the useful figures into a 1 row table that can then be pasted into Excel.
e.g Existing Select Query 1 returns 1 row showing Average Age, Average Price, Total rainfall
Existing Select Query 2 returns 1 row showing Average Weight, Average Salary, Total snowfall
Existing Select Query 3 returns *2* rows: It returns Distance from London, Hours daylight and population for Town A and Town B
I want a select query that returns 1 row showing (6 items):
Total rainfall, Total snowfall, Town A Distance from London, Town A Population, Town B Distance from London, Town B Population.
I've been able to handle getting Total rainfall and Total snowfall. But I cant figure out how to get Town A Distance from London, Town A Population, Town B Distance from London, Town B Population to appear in the same row of the same query results as Total rainfall, Total snowfall.

I have two tables:
tblSITE and tblUSID (joined by SITEID)
and I am trying to create a query which lists each site and the USID with the latest date in its ConstructionDate field (USID and ConstructionDate are both in tblUSID). If I omit the USID from the query and run a totals with MAX on the ConstructionDate field, I return what I would like to, but I want to add the PK (USID) of the record with the latest ConstructionDate for another query, and every way I attempt it the query returns multiple records per SiteID.

I have 2 tables, one called Location and the other called PC Inventory. They both have columns called sites. The query is set to search both tables by site name and return the PC's at that site that match the search criteria.The search form has a drop down menu with all the site names. When you choose a site name from the last, the after update event does a re-query to a subform on that same form. The source object of the subform is set the query.[Forms]![PC Search]![Combo6] - this is the criteria on the query that point to the drop down menu.
Private Sub Combo6_After Update()
Me.Child19.Requery
End Sub
This is the requery that point to the subform (child19)..The problem is that some selections from the list don't return any results to the subform. But there is clearly records that meet the criteria in the table. Example: ABC @ Maryland returns all the PC's at the site. DEF @ Maryland doesn't return any PC's at the site, but there are records with that site name.Even if go into the table copy the site name that isn't working and enter into the search field it doesn't return the results.

Any new data I add to my database isn't showing up when I run a query.I've noticed it on 2 queries. One which is my ChargerSearch query with the field name:
Code:
ChargerSearch: "Charger ID: "+[Charger_ID]+" "+"Scheme Contract: "+[Scheme_Contract]+" "+"Nissan Serial Number: "+[Post_Serial_Number]+" "+"Client: "+[Client]+" "+"Site: "+[Site]
and the Criteria:
Code:
Like "*" & [Enter Search Term] & "*"
And my JobHistory Query which has multiple fields from many tables. With criteria only on the Charger_ID field "[Enter Charger ID]". Both work fine for data that was already there but any new data I've added isn't returning any results when I enter the correct values in the parameters. The data is definitely there in the appropriate tables, it just won't find it on the queries.

Hello!
My problem is the following:
My select works fine when I select 3 fields, but trying to select more than three, when I add two fields more, it doesn't give me the last two fields, being these two fields added lattely in the table...
I mean... I added two fields more to the table one it was created, and the script executed.
After that, if I try select * from table, the recordset does not have this two fields... only the old ones...
Any idea?

I have a query which runs fine, however one of the outputs is a calculated field and i use the Format(someValue,"Fixed") method of specifying the format for the % Change .Here is the query
Code:
SELECT tblTempBearsWeek3.SymbolCode AS [Short Ticker], tblTempBullsWeek3.SymbolCode AS [Long Ticker], tblTempBearsWeek3.[Week 3 Date], tblTempBearsWeek3.Short, tblTempBullsWeek3.Long, tblTempBearsWeek3.[Short Week 3 Close], tblTempBullsWeek3.[Long Week 3 Close],
[code]...
The problem is that the % Change calculated field for some reason comes out as a String. i know this because when I try and sort on that column, it sorts it as if it is text and not a number value i.e. it doesn't put it in Ascending order.

I want an append query to create a new record in a table and populate that record with fields from a form. Some of these fields are free text, others are from combo boxes.The append query adds vastly too many records (albeit all populated with precisely the same information) - and the number it adds seems to depend on which combo box options I choose.
I have a similar append query which pulls information from earlier records in the table, and combines that with free text and combo boxes on a near-identical form, which works fine and always just adds one row.

I've set up a simple query that returns 6 columns of data.This query then shows on a sub-form elsewhere in my DB.The problem is that the query always appears with a horizontal slider. Allowing the user to scroll across to see the other columns in the query...The problem here is that there ARE no other columns of data. They are just empty. I want to restrict the output of this query to ONLY show the 6 columns that i have specified.
I have tried deleting the columns in Query Designer, then save the Query. But every time i re-open it half a dozen or so blank columns are stuck on the end.

I'm running a query from two related tables in the database.the table relationships and the query design. Instead of doing what I want it to do/what I think I'm asking it to - which is show the sum total number of weeks on the program for each student - it shows me the number of weeks for that student just for that claim, not the total for the student overall. I've added some 'dummy data' (2 records in the claim table relating to 1 student), and the query then returns the student twice in the results.

I have two tables Contacts & Allowance. There is a relationship defined between the two based on Contact ID (primary field/contacts - foreign key/allowance). The Contacts table has Firstname + Surname. I have produced a query based on certain fields in both tables however the result is totally pulling incorrect info.

Hello!
I've good a very very strange problem...
I do an insert of a new row into the table TRA. That insert creates an id for the new row.
Right after that I do a select of the new row, trying to get the new id created.
Well, the insert is working fine, but the select sometimes gives me values, sometimes not.
How is it possible?? I've tryied closing the database and opening it again, but is not working anyway...
Any idea??
My code right now is the following: (closing the database, setting recordset to nothing... and still not working properly)
sql = "insert into tra (semana, empleadoid) values('" & semana & "'," & empleadoId & "); "
DoCmd.RunSQL (sql)
db.Close
Set db = OpenDatabase(database)
sql = ""
Set rcset = Nothing
sql = "select * from TRA where (semana='" & semana & "' and empleadoId =" & empleadoId & "; "

I have SQL query/dual sub-query in MS Access that is returning data from the left side of the query FROM correctly, but is only returning one record from the right side of the query FROM. Furthermore, it repeats the display of the one record and it repeats the entire results set with a different one record each time until all the records have been displayed. I expect that problems described as "Furthermore" will not exist by fixing the one record issue. I have tried using all the join types available in MS Access, but none change the result.
The desired output is:
Yellow Blue
11/23/2013 11/19/2013
11/19/2103 10/01/2012
10/01/2102 10/08/2010
10/08/2010 12/14/2007
The actual output is:
Yellow Blue
11/23/2013 11/19/2013
11/19/2103 11/19/2013
10/01/2102 11/19/2013
10/08/2010 11/19/2013
11/23/2013 10/01/2102
11/19/2103 10/01/2102
10/01/2102 10/01/2102
10/08/2010 10/01/2102
The same pattern is repeated 2 more times with Blue values of 10/08/2010 and then 12/14/2007.
Here is the SQL:
SELECT Long_List.Yellow,Short_List.Blue
FROM
(
SELECT DISTINCT BirthDate AS Blue
FROM (
SELECT DISTINCT BirthDate FROM citizens
UNION

What is the best approach to returning calculated results in a query. I have been using nested IIf statements that include DateAdd but I think that I am at a point where there must be a better way.
I want my query to calculate a date based on:
1) A Type field from my table
2) A calculated date based on other query fields.
My query has the following fields:
[Type] [Action 1] [Projected Action 1] [Projected Action 1 Revised] [Action 2]
I want to create a calculated field for [Projected Action 2] that says:
If [Type] is "A" then
if [Action 2] Is NotNull, Null
if [Action 1] is NotNull, [Action 1] + 10 workdays
if [Projected Action 1 Revised] is NotNull, [Projected Action 1 Revised] + 10 workdays
if [Projected Action 1] is NotNull, [Projected Action 1] + 10 workdays
[Code] ....
I would like to keep using nested IIf but I keep running into problems and I thought that there is probably a better way.

I am having a problem with a Dlookup query. I want to achieve the following - I have 2 different tables
Demography Table - consisting of 2 fields, City and Region
For example
City Region
NYC NAM
The other Table totalflow consists of several field, one of the is flow from.
For example
Flow from
NYC
WAS
SEA
I want to do the following. Lookup the Flow from filed in table totalflow, and compare it to City in demography Table. If City = Flow from, return the value in Region. All are text fields.
I have tried following Query, but it only returns the same value for all rows. (from SQL view)
SELECT DLookUp("[Region]","Demography Table","[City] = '" &[Flow from]& "'") AS test
FROM [Demography Table], flowsize;

I have a problem that I haven't seen discussed here yet. (I know this is not good practice, but we're doing this for transfer to another application that wants and accepts data this way)
1) I have a multi select list box.
2) I have code that saves all the values in a semi colon delimeted list in a single field in the DB. (As I said, the application that this data is going to (and from) wants and accepts data in this way)
3) My problem is this. When I re-open my form, how do I get the values that are stored in the database to be highlighted in the multi select list box. I have code similar to this running, but still can't figure it out.
Dim lst() As String
rst.Open sSQL, cnn, adOpenStatic, adLockOptimistic
lst = Split(rst(0), vbCrLf, -1) 'Split the recordset into an array
For i = 0 To List96.ListCount
For j = 0 To UBound(lst) 'lopp until the upper bound of the array
'If the item in the list box = the item in the array then highlight the item in the list box
If List96.ItemData(i) = lst(j) Then
List96.ItemsSelected(i) = True
End If
Next j
Next i
In a nutshell, that's the problem. My list box contains a list of about 5 or 6 things, the user can select any number of them, and I store it in a single field in the DB semi colon delimited. However, I don't know how to return that field to my list box with the selected values highlighted. IE if the list contains A, B, C, D and the user selected A, C the field in the DB looks like this A;C. When I open the form again, I want to highlight A and C in my list box since those were the fields the user selected.
What happens is A;C gets passed to another application (which wants it that way). However, in that other application those values may or may not change, and then they will be passed back to me. (IE the other application may change those values to A;B;D and pass it back to me (which I accept no problem). However, when the user opens the form I want A B and D to be highlighted in the multi select list box
Any help is much appreciated

I have a simple nested query that is not working as expected. My inner query returns 102 records but when I run with outer query I only get 96 records. Below is my query, I don't really want to pull the same fields from both tables but I was doing to test. The values that are missing are those that don't exist with the monthenddate 8/31/2014 - a left join should fix that but doesn't seem to be working ..
Code:
Select distinct a.entity, a.gl_account,a.profit_center,[Open Items_1].profit_center,[Open Items_1].gl_account,[Open Items_1].entity
from(
SELECT DISTINCT [Open Items].entity, [Open Items].gl_account, [Open Items].profit_center
FROM [Open Items]
)a
left outer JOIN [Open Items] AS [Open Items_1] ON
(a.profit_center = [Open Items_1].profit_center) AND (a.gl_account = [Open Items_1].gl_account) AND (a.entity = [Open Items_1].entity)
Where ([Open Items_1].MonthEndDate=#8/31/2014#)
