Return Max / Min Value In Single Query?
Oct 23, 2011
I have a table listing employee names and their birthdates. I have to create a single query that returns the names of the oldest employee and youngest employee. it's easy to return only their birthdays, but i can't figure out how to return the names (with or without their birthday). I can only use a single query.

I'm trying to create a report that's based on a query, and the query has three fields: [PersonName], [PersonDate], [PersonShift]. This table holds records for people that worked on certain days and certain shifts. What I want to do is create a report that gives a graphical calendar display of each day in a month, and on any day that the person has a record (and sometimes there are more than one), I'd like to see just the PersonShift records showing in that day's box.
tblPersons
PersonName PersonDate PersonShift
Jason 4/10/14 FIRST
Jason 4/13/14 FIRST
Jason 4/13/14 SECOND
So if I were to print this report for Jason, I'd get all the days in April laid out like a calendar, and on 4/10/14 you'd see "FIRST" in the box, and on 4/13/14. you'd see FIRST and SECOND in the box. All the other boxes would be blank.how to display the calendar, how to display the dates. I'm able to return records to those boxes by creating 31 separate queries, one for each day of the month, and each query returns records for that day. The queries are added to the report as subreports. It all works beautifully.
The thing is, I'm running 31 queries every time I pull the report. Is there a way to code a single field on a report that will run a SELECT statement on the table using variables that are located in fields elsewhere in the record?
If I have a PersonName field on the header of the report, and I have a PersonDate field in the detail of the report's record, can I create a new field in the detail of that record that runs a SELECT statement on qryPersons, and filters the tblPersons by the PersonName on the header of the report and on PersonDate in the record?
I want a field on a report that runs a SELECT statement on tblPersons, I want the field to return only the PersonShift records for that person based upon the PersonDate. Each of the fields on my report have a CalendarDate field, and I want the SELECT statement to return records where the PersonDate matches the CalendarDate, and again, it should only display PersonShift records.

For each record in my database, there are observation periods which are recorded in the format dd/mm/yyyy hh:mm:ss, titles as follows
1st Obs Start
1st Obs End
2nd Obs Start
2nd Obs End
3rd Obs Start
3rd Obs End.
I have been asked to create a query that will quickly show how many obervation periods commenced in a particular month. What I am trying to do is create a column that will be named Obs Start, and another, Obs End. For each record ID, this would then show as follows:
ID......Obs Start.............Obs End........
1....[1st Obs Start].....[1st Obs End]....
1....[2nd Obs Start]....[2nd Obs End]....
2....[1st Obs Start].....[1st Obs End]....
2....[2nd Obs Start]....[2nd Obs End]....
2....[3rd Obs Start].....[3rd Obs End]....
3....[1st Obs Start].....[1st Obs End]....
4....[1st Obs Start].....[1st Obs End]....
etc.
I could then quickly count how many obs periods started within the desired month.

I am trying to create a form with a button attached to each record that would allow the user to click the button and it would automatically open outlook and fill in the TO:, SUBJECT: and BODY: fields. Here is the code that I currently have:
Code:
Private Sub Command33_Click()
Dim strEmail As String
Dim strMsg As String
Dim oLook As Object
Dim oMail As Object
Set oLook = CreateObject("Outlook.Application")
Set oMail = oLook.CreateItem(0)
[code]...
There are two issues I keep running into:
1. This code opens outlook and populates all of the fields but pastes the email incorrectly. Instead of pasting just the email (email@email.com) it pastes the html tags as well (email@email.com#mailto:email@email.com#) which means that the user would have to delete everything between the #'s in order to send the email every time.
2. I currently have the email BODY pulling from a table but this obviously limits what I can do. I would like to simply encode the BODY within the VBA code. The setup I am looking for is:
one paragraph
a blank line
a hyperlink to a website
a blank line
another paragraph

I have a simple UDF that takes a string and returns a variant, which is an array of strings Example Input "Brick Wall" Return value would be a variant array with first element "Brick" and and second element "Wall" Now I have a table with a field of strings, and I want to make a query that returns all the results from the function, one per line.
So if my input table looks like this
[strField]
"kick the ball"
"return the pass"
my query result should looks like this
[Orig] [new]
"kick the ball" "kick"
"kick the ball" "the"
"kick the ball" "ball"
"return the pass" "return"
"return the pass" "the"
"return the pass" "pass"
Last time I had to do something like this I used VBA exclusively, with ADO objects, but I thought a query based solution would be easier.
With my current data the largest return array size my function returns is 27 elements but I wouldn't want to rely on that number being fixed.

Hi, thanks in advance for any help you can offer. I've got a table that has
Date
Time
Tag ID
Power Level
throughout the day a computer listens to several tags (transmitters) and records the power level of the signal generated by the tag each 3 seconds. What I'd like to do is build a query that gives the Date, Time and Maximum Power level reading for each tag ID. I only want 1 record per tag per day
I've tried using "group by" and max in the query but this gives me all the times throughout the day.
anyway, thanks again for looking
cheers, Shaun

What is the best way to impliment a query in a form so that the user can view the query records, and have the option to print or save the selected record using command buttons?
I tried subforms but I could not get the command buttons to work in the subform after it went into the form, it wanted to print the entire form instead of the selected record from the subform.
So in a nutshell I have 3-4 queries that are built, and I want to have them show up on my form in a format that the user can scroll through the results and select a single record of the results and then print or save that individual record from the form, if such a thing is possible.
Thanks in advance
Todd

I'm new to access, and have discovered its easy to write large queries by breaking them up into smaller queries and having each subsequent query reference the one before it. My problem now is that I want to combine these queries into a single query, so as to make it easier for anyone who comes after me to edit/understand what was done. I can't seem to find a good explanation of how to do this, but it seems like there should be a way.

Hi
I am new to VBA with access. Im wanting to get the result of a query called "qLastRotaDate" into a variable called "datLastRota". The query returns a single date, it is not possible to have more than one result for this query. I have tried different variations of : datLastRota = qLastRotaDate but cannot get any to work. I'm assuming this is very simple yet I cannot figure it out as am very new to VBA.
Any help would be greatly appreciated. Sorry if this has been dealt with in previous posts but I could not find any info by searching the post.
Thanks

Hi,
I am trying to run an append query, but instead of appending the whole table, I would like to only append a single record.
I have an append query, and it works like a charm. I can also get it to work with prompting the user for a parameter (in my case LeaseId which is a primary key). When the user is prompted and enters the LeaseId it only appends the single matching record. Works like a charm.
However, I don't want to prompt the user for the paramater. I want the user to generate the LeaseId based on the selections in two combo boxes.
So far the I do get the right LeaseId, but I have no idea how to actually pass the LeaseId to the query. I've tried the following, but I know it's completely wrong.
stDocName = "approveLease"
DoCmd.OpenQuery stDocName, acNormal, acEdit, "[LeaseId]=" & Me.buildingCombo.Column(0)
Any ideas on how to actually accomplish this?

Hi,
I have a product table in Access, like this:
product_id | product_name | product_quantity
I need to be able to do an SQL update on this table to subtract 1 from the product_quantity field.
I could do this with two SQL queries (SELECT product_quantity, then subtract 1, then UPDATE table) but I'm sure there must be a way just to run one query which subtracts 1 from the field.
Does anyone know how to do this?
Any help would be fantastic, thanks!

Thanks for taking the time to look at my problem first of all. I have a form that shows records but I want a button next to each record that will append that one single record to another table that is built exactly the same, which is for historic records. Not the brightest on Access and I can only manage to append all records.
As an example, I have an employee record that have a task, when the task is complete I want to append the record to a historic table that I can look up later on. However, just that one employee and not all that are in the current table.

I have two identical databases in MS Access. I have created a query in the first mdb file, which retrieves the matching records in two tables.
My problem is that i want to execute the same query created in the database1, on database2, without creating the query in the database2.
I think it is possible, but the query i was trying was not working file.
select * from db1.[Query1] in 'C:DBDB2.mdb'
where db1 is the name of the first database,
db2 is the name of the second database and
Query1 is the name of the query in the db1.
Thanks in advance for the help.

I have 2 calculations in a single query.
1st - ProdCost: [TBLinvqty]*67
2nd - Gross: [TBLinvamt]-[ProdCost]-[TBLfrtamt]-[TBLocamt]
The query runs and works fine but it keeps prompting me for ProdCost but if I hit ok it runs fine.
How do I get it to quit prompting me for Prodcost
BTW, Prodcost is not a field in a table its only the 1st calculation in this query

Each record in my table has six possible sale dates as a result of cancellations. My problem results when a record is sold twice during the queried time frame (SaleDate1 and SaleDate2). Currently my query uses an if statement and if they are in the same time period, it will only return SaleDate1. I would like to see the record returned twice (once for SaleDate1 and once for SaleDate2). Any suggestions?

Hello all,
Is there a SQL function in Access that will allow it to return (as a field value) the name of the table where a particular record was found?
The reason that I want to do this is because I have a single table (Table A) with building address records counted and broken down by state and by month - but some of the records belong to smaller groups (e.g. Zone 1, Zone 2, etc.) that aren't states, but that I want to count in the crosstab as if they were. There are building addresses on Table A that belong to each of these four groups, so I need to somehow match the records on Table A with the appropriate Zone, and place the name of that Zone in the "State" column of the query results instead of the actual state so that I can then count the results in the same crosstab.
I had the intention of resolving this by creating three tables (with the listings of address information for each Zone #), then matching records in Table A to each Zone table in a query by the address field to get each record's appropriate Zone no.(if available), then using the results of this query in my crosstab - :confused: but I can't figure out how to get Access to create a calculated field that lists from which table a resulting query record came from, so I can't continue.:confused:
Any suggestions, if able, would be appreciated!

Sales Rep, Total Sales
1, 100
2, 200
3, 500
4, 50

I need to create a report which delivers the sales rep with the most sales and only that sales rep
e.g.

I have set up a parameter query in Access 2003 that asks the user for the "Section", such as "Admin", "Accounting" etc.
I need them to be able to respond to the prompt with more than one section if they want- sometimes just one, sometimes two or three or four.
So they can get "Accounting" and "Admin" both in the records that are returned.
The code:
SELECT T_ElainesMaster.Section, T_ElainesMaster.Login, T_ElainesMaster.Workstation, T_ElainesMaster.NT, T_ElainesMaster.Barcode, T_ElainesMaster.[PC model], T_ElainesMaster.[Emp Name], T_ElainesMaster.[swap or not], T_ElainesMaster.[Exp Date]
FROM T_ElainesMaster
WHERE (((T_ElainesMaster.Section) Like [What section would you like to include?]))
ORDER BY T_ElainesMaster.Section;
Thanks!

Hey guys, my problem is this:
I want to run a query that runs off of two list boxes on a form. However, I want both these parameters to filter a single field in my query. Why I want to do this is I have several types of accessories made by several manufacturers, both included in the "Description" field. I don't want to include an entirely new field for manufacturer because it's only 4 out of about 5 items that need this.
Is there a way this can be done or will I be forced to include a manufacturer's field.
Thanks in advance
Nathan
