Here's some background on what I'm trying to do. I am building a database that will hold data on 31 parks. Each park will contain many advertisers and each advertiser may be in one or many parks. Theres more to this but i will just stick to what I am having trouble with.
The tables i have made thus far pertaining to my question are:
1. "Parks" table. It has two cols one for ParkID (key) and ParkName
2. "Advertisers" table. It has 9 cols for things such as AdvertiserID (key), addresss, etc...
3. "AdsData" table. This is the problem table. It contains AdID (key) and ad content columns (copy, names, driving directions, etc...). In addition to the ad content however, I need each ad to indicate which of the 31 parks it is located in (one or many) and which of the 16 park activities (things like hiking, swimming...i have another table for these) it is to appear in (one or many).
The only solution I have been able to come up with is to make a table ("AdsData") with 55 columns in it. In addition to the ad content data for each ad, there are 16 yes/no columns for selecting one or more activities for the ad to appear in and 31 yes/no columns for selecting one or more parks for the ad to appear in.
This seems excessive because I have a table with all the Parks in it and I have a table with all the Activities in it. Plus I've been told that having so many columns in a table is a bad, bad thing.
But in my limited knowledge of Access, this is the only solution I can come up with.
I have three tables that contain different columns but linked by a primary column call Name. I want to create a table where all these different columns in the three tables join to form a master table which can be updated regularly either through the master table or the smaller tables. The master table also has the primary column as Name.
If I update the master table with records, it should update the respective linked table and vice versa. I also want to link these tables to my SharePoint site.
Note: except the Name column, none of these tables have any other columns in common How do I go about this?
I have two tables tblCList and tblCode. The primary key of tblClist is an autogenerated number which is the foreign key to the tblCode.
The tblCList has another column names sClist.
whenever I import values from Excel into the tblCode, I need Access to look up the text values from the sClist in the tblClist and insert the appropriate number corresponding to the entry in tblCode.
Is it possible for the primary key of one table to act as the foreign key in another table for more than one columns? What I'm trying to do is create a table for a Committee which will have 1 student and 5 professors! So Can I import the faculty ID for each of the 5 faculty members?When I try creating the second relationship, access automatically creates a new Faculty table for the relationship!
I have a very simple question (I think). I have a table with 2 columns in it, filled with city names and their id's. For example:
city - id rotterdam - rd amsterdam - ad new york - ny london - ld
I have a form with this city-table as a dropdown menu to fill in the control. What i now want is, when I select the city, a different text field named ID must be filled in with the corresponsding city-id. So, how do I fill in 1 field when a edit the 2nd field?

I would like to know if there is a maximum nb of columns to use in a table or at least a prefered max nb. For example i have a table "customers" and inside i have "name" "last name" "age" "gender"..and so on is there a limit? By the way i'm using access 2007
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.
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 a table in Access with 184,000 rows or records of data and 20 columns or field names. When looking at the table ten of the columns represent the identifying information for the data stored in the other ten columns. I need to convert the last ten columns of data into one column with a second column added to identify the original field name. Then end result would be one current record of data being converted into ten records with the original 10 columns of identifying data, a new column containing the original field name and a column for the data value from the original column identified in the new column.
I have been able to do this in Excel using a consolidation pivot table, un-checking the rows and columns then clicking on the final sum value to get a detailed list of the records. Unfortunately there still appears to be a cap because I get a message saying some of the data has been dropped after a little over a million rows.
I am using the 2010 version of Access and Excel.This is the smaller table. I have several others that have up to 200 columns that need to be converted the same way.
I am trying to write a query that will select distinct values from three columns. The table name is Hoods. The columns are C1, C2, and C3. All three columns contain colors and can have the same values, but I only need to have a particular color selected once. For instance, all three columns contain "Black", but "Black" should only be listed once. The result of the query will be used in a drop down list.
The following works for one column:
SELECT DISTINCT [Hoods].[C1] FROM Hoods WHERE C1<>"";
Hi, I am trying to compare two columns' values within the same QUERY table, but I kept on getting the "Data type mismatch in criteria expression" error. What am I doing wrong?
Here is my Select Query Statement: SELECT qryDedparmDedetail.EMP_ID, qryDedparmDedetail.[Employer Amt], qryDedparmDedetail.[Employer Actl], qryDedparmDedetail.[Admin Amt], qryDedparmDedetail.[Admin Actl], qryDedparmDedetail.[Employee Actl], qryDedparmDedetail.[Employee Amt], qryDedparmDedetail.FirstOfSTATUS, qryDedparmDedetail.FirstOfAGENCY, qryDedparmDedetail.FirstOfTITLE, qryDedparmDedetail.FirstOfFORMAT_NM, qryDedparmDedetail.RepUnit, qryDedparmDedetail.FirstOfDEDTYPE_CD1 AS Expr1, qryDedparmDedetail.SumOfNBR, RepUnit.REPUNITDESC, qryDedparmDedetail.LeftType FROM qryDedparmDedetail LEFT JOIN RepUnit ON qryDedparmDedetail.RepUnit = RepUnit.REPUNIT WHERE (((qryDedparmDedetail.[Employer Amt])<>"Employer Actl") AND ((qryDedparmDedetail.LeftType)="01"));
I have a Microsoft Access table with the following columns: A,B,C,D,E,F. In first row of Column A, I have the following string value: "Al,Peggy,Kelly,Bud,Buck" What I would like to do is parse this string as such:
I want to count data from my table ( Table ) and to display result like a dashboard (Desired result ). To count this do i need to write query for every column and then link to final column? i have totally 300 columns to count I am attaching Table & desired result images;
My Approach database contains records relating to nearly 800 sites in London. There are radically different amounts of data held about each site. The database contains a lot of different tables, each containing a different class of information. Not all the sites listed in the database have information in all of the tables.
The unique thing that holds it all together is the unique site reference number. Unfortunately this is split into two separate columns in the Approach database, "Reference" and "Suffix". Not all sites have a suffix. (The purpose of the suffix is to identify sub-sites which are subordinate to the main site reference, but need to have their own individual records.) Because many sites have no suffix, most of the fields in the second column are blank.
In order to link all the tables together in access I need a Primary Key which is unique to each site. In this case the reference/suffix number is the obvious (only) candidate. There is no problem using two different columns to create a primary key. The problem I face is that it doesn't like the fact many of the fields in the second column are blank.
My solution to this is to combine the two columns into one. That would give every site a unique reference, and none of the fields in the combined column would be blank. Can I work out how to do it? All I want is a new column that displays the reference and suffix (if any) in a single field, no spaces.
My database has three tables with many columns. The three tables are identical in the names of their columns.
I want to copy all columns from all three tables together into one single table, giving the respective columns prefix table1-, table2-, table3- since the columns would otherwise be indistinguishable.
I already tried to search the board for "table columns add prefix".
I use Access 2010
I managed to copy all columns together into one table through design-view, but cannot figure out the "add prefix" step.
I am working with other data that has been created by someone else.
There are a number of columns with the same information in (a serial number). What I need to do is get this into one long column so that I can run other queries from it.
So far I have tried using this SQL:
SELECT A1-TX1 POWER AMPLIFIER 1 FROM SM_Cabinet_T UNION ALL SELECT A1-TX1 POWER AMPLIFIER 2 FROM SM_Cabinet_T
[Code] .....
But it is not working - Is it to do with the field names or am I entering something incorrectly?
I'm having problems importing a spreadsheet from Excel for a client.
They are using Access 2003 and Excel 2007, 3.5GB RAM
It works perfectly on my machine - Excel 2010 and Access 2007-2010, 4 GB RAM.
The file is imported in Excel 97-2003 format via a macro using the transferspreadsheet function.
It returns error 3274: "external table is not in the expected format."
There are 1488 rows and 71 columns in the spreadsheet and resulting table - in future additional columns may need to be added representing new critical data.
The interesting thing was that it worked fine on my machine. Then as a trial and error process I cut the file down to 26 columns and it worked fine. 52 columns also imported. But it gave up when there were 71 columns.
if 52 columns * 1488 rows =77,376 record worked, that's more than the magic number of 65,536. but it doesn't like 71*1488 = 105648 records. Is there a limit at 100,000, or some other number in between? I would have thought Access could hold/import much more than this.
Is it possible to have a calculated column based on another table. i have a 1 to many table. the table that is the parent hold a start time. all of the 'many' have an individual time length. i would like a calculated column in the parent table showing the full length. is it possible or will i have to use an update query?
but only one column which is called "Id_rodzajpracy" from
Code: tabela_zdrodlooffset = "tblOffset"
How could I modify red instruction to do inner join?
Code: Dim rec_GoraZlecenia As DAO.Recordset Dim rec_GoraZlecenia2 As DAO.Recordset Dim rec_GoraZlecenia3 As DAO.Recordset Dim tabela_docelowa As String Dim tabela_zrodlowa As String Dim tabela_zdrodlooffset As String Dim s As String
I have 4 tables that store information on guest charges (stayinfo/room rate, fuel charges, bar tab, merch charges) each linked to table carrying guest ID's. Is there a way to combine/merge all the tables into one in such a way that all of the guestID's are in one column, all of the charges are in another column etc? Basically adding one table to the bottom of another.
