I'm working with an Access database with chemical data. The different parameters are in one coulmn each. Some stations don't measure all parameters. I want to create a recordset with all data from a station within a time interval. I will then display the data in a html table, and would like to avoid empty columns.
Is it possible to create a recordset, which only consists of columns with data, with some sort of filter? How do I filter on the column level, and not on the row level?
I have a text file that I will be importing into a new table once a week (every week) that I will need to add about 30 more columns to before I export it to a new text file in preparation for importing it into another Access application.
Is there a way through a query to add the columns without having to open the table and manually add them each week?
I was able to use the UNION ALL qry. But, when I have another file (like original2) that does NOT have all the columns listed in the UNION ALL qry, I get a Parameter value box asking for the missing columns when I run the qry.

The UNION ALL qry includes all the possible resources ( includes all the possible column fields Christan, Johnny, and Steve).
When I run the UNION ALL qry with the original2 file, An "Enter Parameter Value" box is displayed with the mssing column name "Steve".
Is there a way to Map the original2 table into a working table with all the columns, or use VBA code to construct the UNION ALL qry to only include the existing columns? My data has variable columns and I'm trying to avoid the parameter popups.
I have a MS ACCESS 2010 database with a data table which i am trying to create a query from. I have 6 columns of data( one with an ID Field and 5 Name Fields). Below i have made examples of how it first appears as a simple query and the second will show you what i would like it to look like.
What the simple query looks like: [URL] ...
Second what I want the query to look like: [URL] ....
Currently I'm building tables and forms. My first table (called Clients) lists the details of fictional clients. My second table is for invoices.
In my invoices table, I wish to link the column for client reference (note: stored in the Clients table) to the column that precedes it. This column will list the clients’ names and is selected from a drop down list that is linked to the Clients table.
What I want to do (if its possible) is to have the respective client ref. automatically show up in the next cell once I've selected the client to whom the invoice relates?
Am I making sense? Is that possible? If so, how do I do it?
Secondly, how do I do a sum of selected columns for my “totals” column? Basically, I want to add the figures found in several cells that precede it?
I'm affraid my confusing topic title is an indicator of how confused I am by this. I can't even understand the variables well enough to fully utilize Access Help or the Search function here...
What I have is a database hat has column headers that look something like this: Customer_Name, Order_Date, Qty_Ord, Unit_Price, Total_Price
What I'm trying to get is a query output that will have
Customer_Name, Total Orders (in Dollars) for January, Total Orders (in Dollars) for February, Total Orders (in Dollars) for March, etc.
I've been able to set it up to SUM for one month, but not multiples.
I know I'm totally lame (for proof read any of my previous posts) but you guys totally bailed me out the other time I asked a lame question.
Hello World:I have two tables, one called Assets and the other table called Job Sites. the Assets table has several fieldsAssetID - autonumberplus othersthe Job Sites table has two fieldsJobSiteID - autonumberJobSite - text (with about 22 names in it)the I add the JobSite to the Assets table (hiding the JobSiteID) it shows me the expected drop down box but it is BLANK. If I click on any of the BLANK spaces in the drop down, it populates the field. It is behaving as if the font color was white.Any ideas??? I am baffled. :confused: :confused:
I have just created a query so that I may base my report on it. The query ties together 4 tables. I only included the fields that will be in my report. I created the report using the wizard and used my new query as the source but it does not want to work. I tried opening the query and it was empty even though I have entries in the database.
I'm trying something quite simple, adding dates into a table with the aid of an action SQL statement (INsert Into) in VBA.
However, if a date is empty, the value 12:00:00 AM is filled in! I really want that if it a date is set to empty, that noting is added to the table... I can use an if statement though, to fix it, but why does it fill in 12:00:00 AM if a date is empty?? Can you fix it? Or is there no other way?
I have a query that appends records to a table with a constant numer of fields. so sometimes I have fields with no data. is there any way to create query which selects only fields with data.
I am trying to make a query with two tables. Each row consist of a student ID, their name and all their personal information. Both tables are exactly the same. But one table is a link table. That link table gets update every so often from an outside program and the other table is not linked. I want to be able to run a query that updates certain fields called "address changes". I have figured out how to find the updates, but I am having a problem with a field that is blank. If I have a field in the non-linked table that is empty but there is information in the linked table, it does not see it. Is there a way to get around this empty field problem?
I have been going back in a db to the beginning of time and restructuring...I have a field sales person if its null I need to assign a value of 100 to another field representativeid, I have been using the update query to accomplish the update until now. I've tried is null and "" to get this query to update, any idea?
I have an Input form that does not clear the fields after I hit the Save button. Data Entry is set to YES. If I use the navigation bar, there is no problem, but I would like to have the fields empty after hitting the Save Button, so that the navigation bar can be removed. What is wrong?
Hi guys, here is my new problem.I have a form which conatins a subform that shows info from a query.I created a query which shows records from table history when the field comment is like *code 1.the criteria in the query, in the comment field is: [forms]![edititem]![vconcate]In the edititem form i have a hidden field called vconcate which receives the value as follows:me.vconcate= "*code " & me.winecode (me.winecode is integer)after assigning the value to vconcate i display the vconcate value and shows*code 1, as it should be. However, the subform doesnt displays any record.I also tryed to insert the query in the editform, but nothing.if i run the query from the query window, and fill the value as *code 1, it works.here is more info:when the edititem is open, the user has to select a wine code from a combo box. After this selection the values are assigned to me.winecode and the me.vconcate. Because when i open the form edititem these codes are null or empty the subform is empty. Is there any way to refresh the subform via code?any suggestion?
Hey guys......simple problem I have a form with 3 combo boxes.
The 1st combo, called winecode, gets the values from the following sql: SELECT [winecode] FROM wine WHERE winedesable=0; it works.....
The second combo box, called suppname, gets the values from another select, but depending on the previous combo: SELECT DISTINCT [supplier].[suppname] FROM supplier, suppwine WHERE [supplier].[suppnumber]=[suppwine].[suppnumber] And [suppwine].[winecode]=[Forms]![addpop]![winecode]; it works......
The 3 rd combo, called winesubcat, gets the values from a query which takes the selected value from the previous 2 combos. The query works by it self . However, i added the query in the data tab and open the form. then i selected values from the first 2 combos and there is no value in the 3rd combo...... any idea??
When I click a button I have code (below) that checks to see if my Combo boxes are NULL (empty), and if they are it’ll prompt the user to “fill in all fields”. Right now it includes all of the combo boxes on my form. Although, I want it to only include 3 combo boxes (I have 5 on my form). How could I do this, lets say if my combo box names are cbo1, cbo2, cbo3 ?
For Each ctl In Me.Controls Select Case ctl.ControlType Case acComboBox If ctl.Value & "" = "" Then MsgBox "You must fill in all data fields." Exit Sub End If End Select Next
In a previous post someone mentioned a difference between Null and Empty. Is Null is not pulling the nulls but I know those fields are empty. Can someone tell me how to pull in these empty fields. for my calculation I need to get Companies that showed revenue after and didn't show revenue once their contract started.
Code:DoCmd.RunSQL "SELECT tblTrades.tradeID, tblTrades.TradeConfirm, tblTrades.Laurent FROM tblTrades WHERE (((tblTrades.TradeConfirm)=No) AND ((tblTrades.Laurent)=Yes));"
I can seem to find a way to test if the SQL for my record set returns value. I've tried using the if statement with .BOF and .EOF. When there are no records returned for the criteria, there should be a way to test it with IF. I can't seem to figure it out. Using the record count does not work because it also returns at least one record. Help.
Here is the code
Dim rsContacts As ADODB.Recordset
Set rsContacts = New ADODB.Recordset
SQLStr = "SELECT FormatPercent(((43200-Sum(DateDiff('n',[tblOutageDetail.StartTime],[tblOutageDetail.endtime])))/43200),2) AS ElapsedTime FROM (qryOutageTotalMin INNER JOIN tblOutageData ON qryOutageTotalMin.Outage = tblOutageData.Outage) INNER JOIN tblOutageDetail ON tblOutageData.Outage = tblOutageDetail.Outage WHERE (((tblOutageData.System)='PARK PRIMARY') AND ((tblOutageDetail.StartTime)>=Date()-30) AND ((tblOutageDetail.OtgCat)=1))"

I have a report base on a select query but in the report i get the following:
page 1 = record 1 page 2, page 3, page 4 = are empty (nothing to see on the pages) page 5 = record 2 page 6, page 7, page 8 = are empty (nothing to see on the pages) page 9 = record 3 ...........etc... So there are three empty pages between every two pages(records).
I have checked in the settings of the report and all properties but cannot find the solution.
Can any one help me to solve this ? Thanks in advance
This is working fine as long as I input the values for all the fields...when some values are missing, I get the error that Access can't append the query due to validation rule violations...got no clue what to do !
Using expression builder what expression do I use to not display the filed in my query if the field is formatted as currency and is blank (showing £00.00)
I have a form with a subform on it. My subform gets populated by a lookup. On my main form I have an unbound (cboLotIDLU) lookup field and also a text box (LotID) that shows the chosen record. When I open the form my cboLotIDLU is blank but my LotID has an ID in it so the info for that ID is displayed on my subform. I would like everything to open up blank. I've looked around and I can't see where that first record is coming from. How do I get it so everything comes up empty?
Hi, I imported an Excel spreadsheet into Access. As you know, Access will automatically create 255 characters size for each 'text' datatype.
Now the issue is, when I create a query and I specify Right([Field Name],3) I get no/empty results. I know my query syntax is correct, but the issue is, Access is picking up the right 3 character of the 255 field size. But in reality, my field's data are not 255 characters long; the max is probably 30 characters.
So, the question is, how do I go about picking up the 'actual' right 3 characters?
