Multiple Aggregates With Fewest Possible Steps?
Jul 18, 2005
Hi,
I have a table wherein only new data is provided by the user, and fields that have not changed from the previous record are left Null:
Date Field1 Field2
1 B (Null)
2 A 1
3 (Null) 2
Is there a simple way to produce the following results from an aggregate query:
Date Field1 Field2
3 A 2
(Where [Date] is a parameter.)
Right now my process is pretty clumsy, requiring multiple steps to get the MaxOfDate for each Field, then each Field's value corresponding to its MaxOfDate. Not pretty. :(

Is there a way to make a query that has several steps that have to be run in sequence, rather than all at the same time?
For example, I want to create a table that is created from 3 other tables that I download.
The first step would be to append all titles from the first downloaded table, not allowing duplicates.
The second step would be to append all titles from the second downloaded table, not allowing duplicates.
And the same with the third step.
It would be nice to be able to do this with one query, but since it gives me an error because I am trying to do the same thing three times to the same field, I can't. I would really like to avoid having to save this as three different queries, like I've had to do with other multi-step queries.
If there's a way to do this, I'll be able to apply it to several other multi-step queries I have.
Also, if that is possible, is it also possible to have several types of queries in one? Like an append query with several update queries, performed in sequence?
(Note: I'm creating these queries in Design View--I don't know enough to write my own queries in sql, except for my one union query--which I had help with--from here, I think. I can, and often do, alter sql queries that others have written for my own purposes, though.)
Thanks,
Siena

I am working with several reports between Access and Excel and I feel like there must be an easier way to do what I need. Hoping someone can help.
I have 4 Excel files, A.xls and B.xls and C.xls. Each with different fields that I will use to join and extract data to make D.xls.
A is the master file that I need to compare B and C to. I need to create a 4th file that will contain all the records on A and only those on B & C that match A. I am using email and ID as the join fields. A has email, B has email and ID, C has ID. I am joining A & B by email to make query A_B which contains all A records and only those on B that have same email. A_B now has fields email and ID. Then I need to use query A_B to join to C. The problem here is that I cannot use the query A_B to do this. I get an error message and have to export the query to Excel then bring it back into Access as another table to use for the last join. This is where I feel like I am doing an extra step. Is there a way to use this last query for the next join so I can end up with a final file that has all A records that contain B data and C data?
I know this sounds confusing but I hope someone can understand and provide guidance. Thanks!

Hi,
This is my first post here and I seem to like the activity on this forums. Now to my issue.
I have a table with schedules: Event and it's schedule in actual date:
Ex.
Event1 1/1/2007
Event2 5/1/2007
Event3 7/1/2007 (MM/DD/YYYY)
and I have another table which has the event name, time steps and numbers:
Ex.
Event1 1 1000
Event1 2 1500
Event1 3 1500
Event1 4 2000
Event1 5 1500
Event2 1 1000
Event2 2 1500
Event2 3 1500
Event2 4 2000
Event2 5 1500
Event3 1 1000
Event3 2 1500
Event3 3 1500
Event3 4 2000
Event3 5 1500 (I kept the numbers same for all, time steps are monthly)
Now, I can't think of away to write a query to link the dates and the time steps, eventually reaching to some output as this:
Event1 1/1/2007 1000
Event1 2/1/2007 1500
Event1 3/1/2007 1500
Event1 4/1/2007 2000
Event1 5/1/2007 1500
Event2 5/1/2007 1000
Event2 6/1/2007 1500
Event2 7/1/2007 1500
Event2 8/1/2007 2000
Event2 9/1/2007 1500
Event3 7/1/2007 1000
Event3 8/1/2007 1500
Event3 9/1/2007 1500
Event3 10/1/2007 2000
Event3 11/1/2007 1500
Thanks, let me know if there is anything not clear. Pointing me to the right direction to do this helps a lot since I am kinda lost.

MS Office 2003..I have 7 queries that I use to export data to one excel workbook. Inside the workbook are 7 worksheets, one for each query. I have it working but I dont know how to save the exports steps like I did in AC2010.
I export the data by right clicking on each query and select export , then I browse to the workbook and because each query is named differently , it names the worksheet. I have to run these 7 queries each month , so I would like to save the steps and then build a macro that would run all seven steps at the push of a button.
I have saved the steps on a PC running MS office 2010 and the macro works great. The problem is this resides on a PC that cant be upgraded and I need to make it work on Access 2003 .

I'm enrolling medical centers in a new multi-center database. There are a number of steps that must be completed before the center is enrolled in the project. I have a form that serves as a checklist. I want the textbox at the bottom of the form to display the percentage of steps completed. I guess you would have to count the number of fields on the form that are filled in, but I don't know how to do it.

I am using Access 2010 and Excel 2010. I need to have VB script to export the access table 502 records by 38 fields into Multiple Excel workbooks each having multiple tabs. In the Access table each record has two fields: Div and Tab that will be used to name each workbook and each tab (sheet). There are 6 unique "Div"'s to name the 6 workbooks and there are several "Tab" names for each Div (workbook).
Note: These 6 workbooks with multiple tabs were originally imported into Access from one common folder on my desktop by this routine:
Option Compare Database
Option Explicit
Private Sub Command1_Click()
Dim blnHasFieldNames As Boolean, blnEXCEL As Boolean, blnReadOnly As Boolean
Dim lngCount As Long

Excel workbooks would take names from the "Div" field and the tab names would come from the "Tab" field in the Access table. First need to find workbook name (Div - Field) then the look for each sheet name (Tab - Field) to create 1st Excel workbook with all the sheets (Tab) and repeat the process. I think you need to approach of read the Access table one record at a time keying on the "Div" and "Tab" fields in creating each Excel workbook with the associated multiple tabs (sheets) that are written to a common folder.
Note: These 6 workbooks with multiple tabs were originally imported into Access from one common folder on my desktop by this routine.

I want to create a form that allows users to update multiple fields for multiple assets. Below is what I came up with:
Ideally, I'd like the subform to be filled in by having the user select multiple Assets from the S/N combobox field which would then auto-populate the "Type" field. Then they would fill out the appropriate fields they want edited in the top part of the form. They hit save and magic happens. This would also be nice because only assets they want edited would be displayed (easier on the eyes) and no distinguishing would be necessary. To do it this way, I know I would need to use a temp table but I wanna avoid using temp tables.
I know I can do this by adding a Yes/No field in the "Asset" table, setting the "Asset" table as the subform's recordsource, and then putting a checkbox in the subform and allowing them to check the assets that they want to edit (which would also allow me to sort it instantly so that checked Assets are at the top of the datasheet for easy viewing), but I would like to know if there's a way of accomplishing this without the use of checkboxes.
I know I could also use a listbox and that allows them to multi-select items, but I'm not sure if that allows me to group all selected items at the top of the listbox for easy viewing of selected items. Plus it would involve a lot of scrolling (there are over 2k assets).

I have a form with 15 unbound text boxes (daily temperatures) and what I am trying to do after entering the temperatures into the text boxes the user clicks an add button which will add 15 new records into the temperature table
the code I have started off with is
Code:
CurrentDb.Execute "INSERT INTO ColdTemperatures (ProductID, ColdTempDate, Temperature) VALUES (" & Lettuce & ", #" & Me.RealTime & "#, " & Me.Lettuce & ")"
which adds 1 successfully however if i repeat the code above for all 15 this Im assumming will create a potential bottleneck and slow the system down
is it possible to add all 15 records at once? do you think Im going at this the right way

Function GetAllFiles()
Dim fd As Object
Dim strFilter As String
Dim lngItems As Long
Const msoFileDialogOpen As Long = 3
Const msoFileDialogViewDetails As Long = 2

I need to count records based on multiple criteria from two different tables. I have two tables (i.e. "tblTasks" and "tblTaskHistory"). The tables have a one-to-many relationship based on the "TaskID" field. "tblTasks" has a field called "AssignedTo" and "tblTaskHistory" has a field called "TaskStatus". I need to know how many tasks have been "reopened", the "reopened" status is located in the "TaskStatus" field in "tblTaskHistory". I need this count against a unique listing of employees which can be found in the "AssignedTo" field in "tblTasks".

I would like to know which way is the best way to import excel data from multiple sheets in to multiple tables in access.
For example data from Sheet1 -> Table1, Sheet2->Table2, Sheet3->Table3 etc...
I have tried using this:
Cmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel5, "Table1", "C:Importedfile.xlsx", True, "Sheet1!"
Ironically, data from Sheet2 and Sheet3 seem to be properly imported in to table2 and table3, but some of the data from Sheet1 seems to be missing in Table1 after import.
Any other ways to import the data?

I am trying to build a newer database 2010, based on an older one,2000, that has been locked tight and I cannot see the modules to kinda get a reference of where to start. I am trying to find a VBA code that will allow me to import a several text files to one table. The text files are all in the same format but I cannot remove the page headers and footers to get the table to look right. I have attached an example of the text file i am trying to import but it is a stripped down version for information protection.
Also, it appears in the old Database Table once imported as:
J.Smith 1234 01 ABCD ABCD HGJV 2345 ABCDE ABC6 Qual Date Date
J.Smith 1234 01 ABCD ABCD HGJV 2345 ABCDE ABC6 Qual Date Date
J.Smith 1234 01 ABCD ABCD HGJV 2345 ABCDE ABC6 Qual Date Date
J.Adam 1234 01 ABCD ABCD HGJV 2345 ABCDE ABC6 Qual Date Date
J.Adam 1234 01 ABCD ABCD HGJV 2345 ABCDE ABC6 Qual Date Date
J.Adam 1234 01 ABCD ABCD HGJV 2345 ABCDE ABC6 Qual Date Date
If I could import the text files and end up with a table like this, it would be all i need as i could run all the queries i need from this.

A small issue I was wondering of for a few day . Is it possible in SQL query to SELECT multiple fields from multiple tables ? Example for the question is
Code:
dim my_var as String
my_var = "SELECT Emp_FName , Emp_LName , Emp_Adress " _
& " FROM Table1 " _
& " AND Emp_Date_Of_Payment , Emp_Sum_Of_Payment " _
& "FROM Table2 " _
& " WHERE Emp_ID = 3 "
Is this code actually valid in SQL gramatics , and is it usable if passed to a Recordset variable ( rs = CurrentDB.OpenRecordset(my_var) ) ? Just FYI - The two tables are not related and I want to keep them that way (If possible relate their records just via SQL/Vba )

I have the following problem.
I have 3 tables made up of ID and NAME and other parameters.
NAME is unique field in each table, whilst ID is not unique. the three tables share the same fields, but can't be combined due to the NAME field not being unique throughout.
Now I have a single table that has a unique ID so I want to make a 1-inf relationship between this table and all three. the problem is how do I look at all three tables at the same time instead of having to insert subdatasheet on only one table.
see attached picture for the relationships.

I am trying to create a simple Search form in Access where a user can select a desired record and query multiple tables using the inputs.
I would like them to be able to query Retailers, Distributors and Products.
The 6 tables are linked as follows:
Although some of these tables are not included in the query, they are required to ensure relationships.
Retailers -- Uses (RetailerID,DistributorID) -- Distributors
Retailers -- Orders (RetailerID,ProductID) -- Products
All retailers have at least one distributor BUT a retailer may or may not have ordered any products.
I have created my form but the query linked to the form is having some trouble. It is only selecting those records that have ordered products. For example, if I query a retailer name only and it does not have any ordered products, it will not display. Is there a problem with the table joins? The SQL for the query is displayed here:

I created the below query to come up with a new form. When I enter a single parameter, it works fine. When I modify the code and enter multiple patameters, it also works fine if I do not enter any information for the parameters. But once I enter one of the parameters information, then it does not come up with anything. I double checked and made sure it was typed in correctly. Is there a trick when entering multiple parameters on a query?
SELECT [JE 06 Log].[Operational Region Name], [JE 06 Log].[Period Name], [JE 06 Log].[Source System], [JE 06 Log].[Source Name], [JE 06 Log].[Category Name], [JE 06 Log].[Associated Category Name], [JE 06 Log].[JE Name], [JE 06 Log].[JE Base #], [JE 06 Log].Area, [JE 06 Log].[Line Description], [JE 06 Log].[Natural Account], [JE 06 Log].Description, [JE 06 Log].[JE Entry Date], [JE 06 Log].[Debit Amount], [JE 06 Log].[Credit Amount], [JE 06 Log].Amount
FROM [JE 06 Log]
WHERE ((([JE 06 Log].[Period Name])=[Enter Period]) AND (([JE 06 Log].[Source Name])=[Enter Path]) AND (([JE 06 Log].[JE Base #])=[Enter Base Number]) AND (([JE 06 Log].[Natural Account])=[Enter Natural Accnt])) OR ((([Enter Period]) Is Null) AND (([Enter Path]) Is Null) AND (([Enter Base Number]) Is Null) AND (([Enter Natural Accnt]) Is Null));

Here is the situation that I'm hoping that someone can help me with. I'm working with a database that tracks our condo units - from prospect coming into the system until we close them as a buyer. All the units are setup in the system so a salesperson will select from the units available. All that works fine when I create reports. The problem is trying to get the parking and storage on the same reports with the unit information. The problem is that there are multiple parking/storage units "attached" to a single unit and I cannot figure out how to get them to all appear on a single row of the report. As an example -
I have units A, B, C
Parking units p1,p2,p3,p4,p5,p6
Storage units s1,s2,s3.
Unit A uses parking units p1, p2, p5 and storage unit s2.
Unit B uses parking unit p3 and storage unit s1.
Unit C uses parking unit p4, p6 and storage unit s3.
How do I write a query/report that would show:
Unit Parking Storage
Unit A p1, p2, p5 s2
Unit B p3 s1
Unit C p4,p6 s3
Thanks,

I have three tables. Risk, Names and RiskAndNamesJunction table. I have the junction table because I have many to many relation (meaning many people can be connected to one risk and many risks can be connected to one people).
The problem is that If I make a query to show the people related to the risks, if there are many people for one risk then it will put the people in different rows. Meaning that for risk 2 I will have three rows, because there are three people connected to this rows. See the attached file!
What I would like to do is to have a query which (in case there are more than one risk owners) puts the second name in another column, the third name in another column and so on. So I will have only one row per risks.
The attached file is a dummy file, so there are only maximum three names per risk. In the real file the maximum is five names per risk. So I am talking about no more then five extra columns. (So I am talking about a query which would put the first finding in the first extra column, then the second item in the second and so on till five. It there is no third or fourth or fifht item then the columns remain blank).
Unfortunately I have to do this because our mother company works with excel and they are sticking to this format in excel.

Ok, I have a form where new clients are entered into the system. We would like to have an automated check that could be run which would check several different fields and compare them to several different existing fields in two different tables to see if the same name shows up. What is the easiest way to go about doing something like this?
Thanks.
