Max Columns/Fields In A Query
Nov 28, 2007
Could anyone tell me if there's a hardcoded maximum number of fields/columns in a query?
I ask, because through some experimentation and the urging of others on the boards, I've finally taken a look at the SQL view of a database and found it rather easy to understand. There, I found I had more flexibility filtering a Query via SQL in comparison to the query design window. (unlimited "Or" vs. 8).
So, even though there's a definite number of columns in the Query Design window, can I ignore than and just enter what I need in the SQL view?

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.
Example:
original1IDDateGroupChristianJohnnySteve 18/5/2013A1528/5/2013B338/5/2013C2348/5/2013D2358/5/2013E5
original 2IDDateGroupChristianJohnny18/6/2013A212528/6/2013B2338/6/2013C2248/6/2013D22
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 been looking on the forum for some code that would bind all columns (fields) starting from column 15 to 26 to a combo box
for example....
Field 1 Field 2 Field 3 Field 4
data1 data2 data3 nodata
Combobox
data 1
data 2
data 3
kind of like a grid
based on the record I select in my form the combo box will show the columns that have data for that record.
It is trycky but I have no idea how to get that started
Thank you all for your help

I have been pulling my hair out over a query application and I'm looking for some help...
For instance, I have a table with [PrimaryName], [SecondaryName] and [JobDate]. I want a query that will display if there is more than one occurrence of the same name in either name field on the same date.
If it were just one field I could do this using GROUP BY and HAVING but because I need to check both name fields I'm stumped. I tried a union query but that seems to group multiple occurrences together as one entry.
Any help is appreciated.

I have Two tables one table has a Master list of products (ProductMaster) with a Unique product code (ProductMaster.UQ_ID).
The second Table has Order data. The Second table (OrderTable) is where I will enter the product code (UQ_ID) which is the unique Identifier which is also in the ProductMaster. As soon as I enter the Prodt code in the OrderTable I should have all the related fields filled in from the Product Master.
Columns in The ProductMaster = Product_ID, Product_Manucaturer, Product_Weight, Product_Color, Product_Size
Columns in The OrderTable = Product_ID, Product_Manucaturer, Product_Weight, Product_Color, Product_Size, Order_Date, Ordered_By
The columns marked in red are the ones that will have to be automatically fetched from ProductMaster
The data in the second table should be populated from the ProductMaster as soon as I enter the Product_Code. The rest of the details Can be filled manually filled in.
Is it possible to do this with Access. I have tried different expressions in the Fields without much use. The Documentation from Microsoft is very weak. If someone knows a solution or where the documentation is, please help.
Thanks

Hi everyone,
I am working on a database to manage newsletter subscriptions. Each subscriber record has the option of having up to four email addresses registered to his/her name.
Is there a way to check for duplicate email addresses in the entire database? It would have to compare all values in all four fields of all records.
Any ideas on how to implement such a thing? I'm clueless...
Thanks!

Hello..
In one of my tables I have a field with the following characteristics:
Listbox
row source: SELECT Category.CategoryID, Category.Category FROM Category ORDER BY Category.CategoryID;
row source type: table/query
bound column:2
column count: 2
This gives the user the opportunity to see the category as well as the categoryID when choosing, however once selected only the CategoryID (which is a number) is visible.
I would like to put the same option on one of my forms, but Im not succeeding at this. How can I do this? Is this possible?
This leads me to my next question: If I want to load the information from the form and compare it in VBA with the one from the table, is it seen as a number or a string?
I hope it is clear..
Any thoughts on how to deal with this??
Thank u..
Stacey

I have a large query that has information from accounts sorted by date, account repeat but they are always associated with a different date. I'd like to create a report where each date has it's own column with an associated field displayed as the information in the column. However, as data is added to the table I'd prefer to do it without having to make a query to filter each date each time information is added.
The information is added in bulk with all the same dates, so ALL accounts (excluding newly opened accounts that may have no information with a certain date) should have information for each date - there will not be single accounts with their own date. For example: An account numbered 12345 with data of 57% on 1/2/13, 63% on 6/2/13, and 89% on 12/2/13. I'd like each of the dates to have their own column, with the account numbers as the row and the percent data to show under the date they are associated with. how to manage this in a report, or if it is possible.

What is the correct way to save the values in a listbox column to the fields of a table? I can use rec("field1") = Me.list16.ItemData(Varitem)and that records the bound column to field 1 but how can I save the unbound columns to other fields in the table?

I have a big Excel file with payroll information about employees. Per employee per date, there are a couple of rows with mostly identical data (such as the employee's home address) but 2 differences: one will have paycode A with amount B, another will have paycode C with amount D, etc. I want to simplify the file to have 1 row per employee per date: in the example given that row would have paycode A with amount B as well as paycode C with amount D, in 4 separate columns.
I think I can technically solve this by creating Excel files per pay code/amount, and then linking them together by person and date, 1 by 1, through Access. This is feasible because there aren't that many different pay codes. But still, I was wondering if there was anyway to solve my problem in Access itself.

Currently what I have:

The list I have will be much longer and will be changing frequently, which is why I can't just go on excel and manually do this.

Hi everyone....
I have imported a data sheet into Access that had certain columns a different color...green...they were colored so that the end user would
know which columns were to have input. (visually)
Is there anyway that I can keep this format or color the columns in Access?
Also the end result is from a Query...does that make a difference ?
Thanks....

Hi all,
This is a strange one. I have a VERY simple query that runs directly off a single table which contains about 7 fields and one PK. I am pulling through 4 columns from this table including the primary key. I am renaming the columns using the format "NewName: Record_Id" format. I have also tried changing the caption on the query column properties.
Basically, the problem is that I save and close the working query but when I either close the database down or make a change to another form or query, the column names all get changed to a single value of the table, currently "Report Title". When the query is run, all the columns are shown with the same header name and the data results are all the same.
I have checked my relationships and they are fine and I have also done a compact/repair but without any luck. Can anyone please help me?
Thank you.
Gareth

Hi folks.
I've been looking for an easy way to have 12 columns in my query which are each of the 12 months and are all using the same date field "dateSent". So i'd want to just use the month part. within the actual columns there will be a disbursal field which will tell a user how much money has been sent (if any) on that month. then If done correclty, it could be analysed in Excel.
I've attached an example of what is required of me. I'm expected to have the same format but i'm unsure how I'm going to go about this.
I've attached an example. Maybe someone might know a good way to do this and perhaps point me in the right direction
I appreciate all help
Thanks.

I have a problem trying to sum a numeric column based off another column in the same table.
What I am trying to accomplish is to sum a numeric column if a corresponding column is Not Null.
I have uploaded my sample DB that to illustrate my problem. The query I am testing with is called Query1 and I am looking at summing point values from the task table grouped by the test case those tasks are in. I can easily sum the total number of points for each test case. But when I add another field to the query to sum the point values of the task in the test case that have a date entered into its corresponding date field it will not sum them correctly.
The result I get is the same sum total is shown for all three fields in the query.
I have tried several attempts at making criteria for this to work but nothing seems to work the way I want it too.
Here are my attempts:
IIf(Not (Sum([Task].[Points]))=IsNull("Attempted_Actual"),Sum([Task].[Points]),0)
IIf(Not (Sum([Task].[Points]))=IsNull("Completed_Actual"),Sum([Task].[Points]),0)
Not IsNull("Attempted_Actual")
Not IsNull("Completed_Actual")
My question is:
Is it possible to do want I want all in one select query or would this be something to code in a VBA module and then just call that module in a report?
My plan was to do this all in a query then build a report to display this query.
I have attached my dummyDB file and you can look at the Test_Case Table and expand each test case to see the data I have populated.
Any guidance would be appreciated.
Thanks,

Hi. I am trying to do a query on a table that has 3 columns
ID, Person1, Person2
I want to query the data to find out how many rows each person's name appears in either Person1 or Person2.
I don't need seperate counts for when each name appears in Person1 or Person2, just the total for each person.
Result example that I'm looking for:
If table contained:
1 Eddie Sam
2 Pete Max
3 Sam Pete
4 Dave Eddie
Query to look like:
PersonsName Total
Eddie 2
Sam 2
Pete 2
Max 1
Dave 1
Surely this is easy to do?
Anyone? Thanks. Martin

I run a query with several columns. The first column in that query is full of individual names; about 50. I have another spreadsheet with three names. I used to be able to set a criteria or a filter (whatever you want to call it) in a query that when "Run" would only return to me the names from the spreadsheet with 3. Not a drop box or a pop up where I have to fill out the name, just a spreadsheet with all the transactions that occurred with these specific three individuals.

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?
Thanks,
David

Hi, everyone. I've been reading this forum for several days now and the information I have picked up here has been wonderful. Thanks. Unfortunately, I haven't been able to find what I'm looking for on a problem I'm having. I apologize for the long post, but I wanted to include as much information as possible. Thanks for taking the time to look at my problem.
My Background: I am a Computer Managed Maintenance System Planner for a foundry. I am responsible for the administration of all maintenance and repair records for the plant’s mobile equipment (dump trucks, fork lifts, etc.) I’ve been using Access as a report writer for several years. I have pretty good understanding of report writing and basic query writing, although I have never used pivot tables or crosstab queries, and I have only used amend/update queries a few times. I have a novice’s understanding of relational databases and I recently picked up a book on VB for MS Applications and have been devouring it. The rest of my limited VB knowledge comes from reading these forums, so my programming knowledge is still in its infancy.
What I’m Using: I am on a network that uses Windows 2K, to which I have only regular user privileges. We use an Oracle database (it is used for everything in the plant) with a third party CMMS. I use Access 2002 to do my report writing. I have a small database set up that contains links to the necessary tables in Oracle and a few tables I created to help “massage” my data for queries and reports.
My Problem: Our CMMS app is only set up to retain the current and the previous hour meter/mileage readings. I need to be able to retain all my hour/mileage readings, however, so that I can track up/down time, utilization, etc., over several different periods of time, including years.
What I Want To Be Able To Do: I want to archive my hour/cycle readings in a table so that I can reference them for later queries and reports. A couple of typical questions I want to be able to ask of this information are
1)“What was the last known hour/mileage reading for this/all equipment on <date>?”
2)“How many hours/miles have passed between <date1> and <date2>?”
What I Have Done So Far: I’ve done research into crosstab queries and pivot tables. I don’t fully understand these, but they don’t seem to be what I’m looking for. I could be wrong, though. Then I got to thinking that the easiest thing for me to do might be to make a button on my main form that would run a query to append the hour data from the db to a table I made to store the info (tblMeterArchive). The table would have a column for the Equipment# and then the append query would create a new column with today’s date as the heading and dump the data into it. The problem is I can’t figure out how to get a query to add a column to a table and stick today’s date in the heading. I’ve searched these forums and I’ve done a Google, to no avail. I have even taken time to just start going through every thread to see if this sort of thing has been discussed before. So far I haven’t found anything and my boss is getting a bit peeved at the hours I have spent working on this so far this week.
So, my question is can an append query create new columns in a table? Or, am I barking up the wrong the tree and there is a better/easier to accomplish my goals? Even a link or pointer to the proper way to search for the information I need would be much appreciated.
Thanks again for taking the time to look at my problem.

Is it possible to total columns in a query? Right now, I have a query that produces the following column counts, but I'd like to total Pending, Overdue, etc. This data is being displayed in a subform.
Process Pending Overdue Total
-------------------------------------
Engineering 1 2 3
Procurement 0 6 6
<etc>
-------------------------------------
TOTAL 1 8 9 <- this is the line I want to add
Here's what the query (qryStatusRptB) looks like thus far:
Field: Process
Table: tblProcesses
Total: Group By
Field: Pending
Table: qryStatusRptA
Total: Sum
Field: Overdue
Table: queryStatusRptA
Total: Sum
Field: TotalRecords: Count(*)
Table:
Total: Expression
Can someone explain how to get the TOTAL ROW in here? (I can do it via another query, but that won't work since the data is displayed in a subform. I've tried crosstabs without success.)
Many thanks,
Christine
