Why this SQL will return only one query maximum?
DateLimiter: (SELECT Date_Retro_Fees_Rate FROM tblRetroFees AS Alias WHERE Date_Retro_Fees_Rate = (SELECT FIRST(Date_Retro_Fees_Rate) FROM tblRetroFees AS Alias2 WHERE Alias2.Date_Retro_Fees_Rate > tblRetroFees.Date_Retro_Fees_Rate AND Alias2.Id_Product = tblRetroFees.Id_Product) AND Alias.Id_Product = tblRetroFees.Id_Product)
A picture of the table is included.
Basically in the query I need a Collumn to only output the greatest value that is given within the sub query. If that makes sense?
Eg. Tenancy start date must be the highest date against the date the property was added back to the system - for post development properties.
At present the it's returning previous tenancies from pre development.
Any way to build something into a sub-query that says 'if no records are found, return '0' or some other string'?
Otherwise is there a way to make a master query ignore sub-queries if they return no records?
Allow me to explain in more detail: I have a series of sub-queries, most of these take the sum of several fields from a number of different tables, and I have a main query which combines all of these, to be used as the basis of a summary report.
These queries aren't a problem, but I have a few other essential queries which take the modal (most common....) entry for fields which aren't numerical. So I can't use the sum function.
Now, if all the sub-queries are working then so does the main query, however if one of them fails to find a result, then none of them show up in the main query. I don't know why.
The issue is that depending on the date range selected, some of the tables targeted by the sub-queries don't have any records at all, so when they are run they return nothing. The sum queries can handle this since they just return 0, but those searching for modal records just find nothing (not 0's and not null fields, just blank across all rows).
Here's an example of my sql statement for the modal queries.
Code:
SELECT TOP 1 Trends.Trend AS ModeTboxTalk, "1" AS [Key]
FROM Trends INNER JOIN [Toolbox Talks] ON Trends.TrendID = [Toolbox Talks].TrendID
GROUP BY Trends.Trend, [Toolbox Talks].TrendID, [Toolbox Talks].TalkDate
HAVING ((([Toolbox Talks].TalkDate)<=[Forms]![WeeklyReportSelect]![WeekBox] And ([Toolbox Talks].TalkDate)>[Forms]![WeeklyReportSelect]![WeekBox]-7) AND (([Toolbox Talks].SiteID)=[Forms]![WeeklyReportSelect]![SiteBox]))
ORDER BY Count([Toolbox Talks].TrendID) DESC;
- FYI the weekly select form is where users select the week and site they want to report against. So it would be really peachy if I could tell the above to say something like 'no trend this week' if indeed there were no records.
I cannot get my query to return result when I enter the month of "June" as search criteria. June is listed in the table and query, every other month is returned except June.
I have attached two example for your reference.
I have several queries that perform an audit on data. I want to create a form that has two buttons, multiple labels and textboxes. When the first button is pressed, it runs all queries and returns a count of the records within each query into the corresponding textbox. Then I want a a button that will clear all textboxes. I don't want to see the queries, I just want them to run in the background and the count results to be populated in the textboxes.
So for example, it would return:
Check1: 3
Check2: 6
Check3: 2
Check4: 0
I have a query that returns several calculated fields. One of them is simply derived by simple summation of the others. If this calculated field returns a negative number, I need it to show as a zero.
The only way I know how to do this is by an IIF statement :
Code:
SELECT [fld1], [fld2], [fl3], .....
IIF(([fld1]-[fld2]-fld[3])<0,0,([fld1]-[fld2]-fld[3])) AS fld4
FROM...
(The above doesn't suggest that [fld1], [fld2] etc are calculated fields - I just wrote it like that for succintness - they calculate fine, there's no issue with them...)
Is there a more efficient way of doing this? I find IIF's a bit tardy, possibly because they evaluate for both True & False eventualities, regardless of the condition, and this query is going to run against a fairly large dataset so any performance lag is going to be exacerbated.
My quiery is supposed to search through a table of names, and find the latest timesheet entry date for each name, as follows:
ID: 1
Name: John
Timesheetdate: 1/1/2005
ID is specific to each name.
I want the result to be a single row for each ID/name, and to return ONLY the latest timesheetdate (this could either be the maximum value or the latest entry).
I have a feeling that this is a simple problem, but i just dont have the knowledge to do it, any help would be greatly appreciated!
I have two functions both should have the same results but they do not.
Public Function DefaultGreeting() As String
On Error Resume Next
DefaultGreeting = "Dear " & [Forms]![frm_contacts]![Dear] & ":"
End Function
Public Function DefaultBodyText() As String
On Error Resume Next
DefaultBodyText = [Forms]![frm_e_mailing]![mess_text] / this equals this just pulled from a table "Dear " & [Forms]![frm_contacts]![Dear] & ":"
End Function
I have a table that has 3 columns: Unique number, Date, and Results
I want the user to enter the unique number and date into the form. Then the "results" column/field will autopopulate a 0 or 1. I want it to populate a 0 85% of the time and a 1 15% of the time. This should be cumulative (meaning not every entry has a 15% chance of being 1). Is this possible?
Hi there !
I display some buttons on my Form. I should do an SQL request to know how many and what the button should display. It works fine with a RecordSet.
Now I want to move the code that do the stuff to a function. I read that I can't return a pointer to a RecordSet and I should used a variant with a getrows.
So I try this :
*here is my function
Function get_nom_operation(ByVal cnn As ADODB.connection) As Variant
Dim requetteSQL As String
Dim rst As New ADODB.Recordset
requetteSQL = "SELECT libelle " _
& "FROM operation;" _
rst.Open requetteSQL, cnn
get_nom_operation = rst.GetRows
End Function
* and here is the code that call the function
Dim res As Variant
Set res = get_nom_operation(conn)
Dim i As Integer
'i = 1
For i = LBound(res) To UBound(res)
Set Obj = Me.Controls.Add("forms.CommandButton.1")
With Obj
.Name = "monButton" & i
.Object.Caption = res(0,i)
.Left = 14
.Top = 25 * i
.Width = 60
.Height = 20
End With
'ajout de l'objet dans la classe
Set Ge = New gere_event
Set Ge.CButton = Obj
Collect.Add Ge
i = i + 1
Next
But it doesn' work, and I don't know why...
The error doesn't show where the code is stoped, but only show the call to display this form.
someone could show me some way to find the solution please ?
Thanks a lot.
My boss has a form based on a rather large table with a lot of records/fields and she wants to be able to have a field where she can enter something and it will seach every record in the table and return the results in a table. How do I do this?
View 9 Replies View RelatedI am working with Access 2010, on vista. What I have is a query made up of two tables, one product the other inventory. (see below) query.jpg
In the product table i have a field called "minimum reorder level". In the inventory table i have two fields one called "number in stock" and "number on order". What i want to happen is "number on order" to be filtered by the result, if the "number in stock", is less than "minimum reorder level", if it is, have the result placed in the "number on order" field. EG. if the "number in stock" = 2 and the "minimum reorder level" = 5 then 3 would be placed in the field "number on order" and only the second record from the query would be visible (see below) Query result.jpg The result of this would mean that the field "number on order" would be populated with the result and the and query would also use this to filter the record.
All using access 2010. Here's the situation. I built a searchform according to datapigtechnologies video. Used a query with criterias on fields i want to search on the form: ex.
Code:
Like [frm]![frmMyform]![MyField]
It worked fine i thought until i ran the same query outside the form without the criteria field. I filtered the query for the same result and the one used on the search form did not return all data records for that particular result set. Ex. on the searchform; I select the fields I wanted to filter then ran the query. I come up with only 9 records when it should be 18 I get with running the exact same query without the criteria and manually filter the results.
I there is no result in query, I need the default result zero in my form field. I only use query wizard to create queries.
View 5 Replies View RelatedI am doing an outline design of a database system to handle the results from an archery competition in a couple of weeks.
Currently I have a table with a primary key to hold the information on the competitors (name, age etc.) and this is linked to a table via a foreign key (the archers name) to enable multiple scores to be recorded against each archer.
For the purposes of the competition only the first score shot each day is valid and so I am using a yes/no box to filter out these results.
What I would like to do is then filter the results such that only the largest of these first session scores is displayed for each archer. (i.e if archer A shoot 578 on day 1 and 585 on day 2 i would like the database to only report the 585, and similarly for the other entries).
i I have two queries.. What i'm hoping is to combine the result into one query but not in one column only but instead the result of the second query should be beside the first query.. The result of the second query should be added as a new column.
First Query
SELECT tbl_uSers.UserName, Count(tbl_rEceived_eMail.EntryID) AS eMailReceived
FROM tbl_rEceived_eMail INNER JOIN tbl_uSers ON tbl_rEceived_eMail.UseriD = tbl_uSers.UseriD
GROUP BY tbl_uSers.UserName;
Second Query
SELECT tbl_uSers.UserName, Count(tbl_rEceived_eMail.EntryID) AS eMailProcessed
FROM tbl_rEceived_eMail INNER JOIN tbl_uSers ON tbl_rEceived_eMail.UseriD = tbl_uSers.UseriD
GROUP BY tbl_uSers.UserName, tbl_rEceived_eMail.ProcessedYN
HAVING (((tbl_rEceived_eMail.ProcessedYN)="Y"));
I am trying to combine the result of two specific (and different) queries on a set of loans. As a result I have to sets of query results:
+ result query 1: with first field LoanID and several other fields
+ result query 2: with first field LoanID and several other fields
Now I want to create a list of the combination of all LoanID's, without duplicates.
How do I do that? I read about UNION but that appears to work only on tables.
I am looking up a product based on a unique code in tblProducts...I need to return one of two values
If the value of [Product type] = "multi" then return "multi"
else
If the value of [Product type] = "solo" then return the value of the non empty field in a range of fields
for example
tblProducts
PID (key) | PACKAGE TYPE | RED | YELLOW | BLUE
C13T0714010 | single | <empty>| yellow | <empty>
C13T0754010 | multi | red | yellow | blue
query
C13T0714010 returns "yellow'
C13T0754010 returns "multi'
Hi,
I have created the following function in my datebase so that i could specify the date a query works from.
Option Compare Database
Function GetParmValue() As Date
GetParmValue = InputBox("Please enter the date you wish to update!?")
End Function
I have a button on a form that runs the query in question, there is also an identical query that needs to be ran using the same result from the input box but rather than it display the input box twice i wondered if there was a way i could use the result from one of the boxes with both queries!?
Here is the code for the button;
Private Sub bImport5_Click()
DoCmd.SetWarnings False
DoCmd.OpenQuery "Update"
DoCmd.OpenQuery "UpdateFuture"
DoCmd.OpenQuery "MoveFuture"
DoCmd.SetWarnings True
MsgBox "Files have now been updated to the specified date and moved to the Future Dated table!", vbOKOnly, "Update Complete"
End Sub
Any ideas guys?
Many thanks
Tim
If you have a form that is based on a select query that has selected no records, the form will display as totally blank.
One way to avoid this is to ensure that the query is always able to select at lest one record; but Is there a way a message can be displayed if no records are selected?
I'm trying to create a query which returns me the next higher number..My table: tblPersons
Code:
ID, Name, balance,
10 John 1000
11 Alice 2000
12 Bob 3000
My query:
Code:
SELECT TOP 1 name FROM tblPersons WHERE( (balance)>([InputBalance])) ORDER BY balance ASC
Input:
[InputBalance] = 500
Result: John
[InputBalance] = 1234
Result: Alice
[InputBalance] = 9999
Result: EMPTY
Result should be Bob
it's possible to combine this logic into one query?
I have a query which i need to get Zero as a result if NULL value. How Can i do this ? Present SQL code is as follows;
SELECT tbl_Impts_main.Bkg_number, Count(tbl_Impts_main.Bkg_number) AS CountOfBkg_number
FROM tbl_Impts_main INNER JOIN tbl_booking ON (tbl_Impts_main.Voyage=tbl_booking.Voyage) AND (tbl_Impts_main.Vessel=tbl_booking.Vessel) AND (tbl_Impts_main.Bkg_number=tbl_booking.Bkg_number)

How can list the contents of one field columns in one row in a report.
Example:
ID: 1
A1
A2
A3
A4
Should be: ID1 - A1, A2, A2, A3, A4
I have a combo box as a value list and all the values apart from one are valid data entries in the table but I want to combine two of the values and then get the query to run if the combined values are selected. The value list is this:
(All);Brand1;Brand2;Brand1 & Brand2;Brand3;Brand4
The criteria in my query is this:
IIf([Forms]![MyForm]![Brand]='(All)',[MyTable]![Brand],IIf([Forms]![MyForm]![Brand]='Brand1 & Brand2',"Brand1" Or "Brand2",[Forms]![FrmCustomListATM]![cbBrand]))
Its the OR part that doesnt work.
I have record like below:
id s q
1 11 11
2 14 15
I want to sum record 1 and record 2 and put them in next record.
I have a POLEFFDATE field with dates in date/time format. A single record has POLEFFDATE equal to 12/15/2013. I calculated a simple field called EVALUATE as follows: IIF([POLEFFDATE]< 1/1/2014,1,0). EVALUATE should equal 1 for this record, but it equals 0. Why ?
