Diff between unique value and unique record
I have a Query that makes a report and I noticed that I'm getting some errors in my output. As far as I can tell, all records are unique, no duplicates, but when my Query properties is set to Unique Values, YES, I get 28 results/records but when I have Unique Records set to Yes, I get 29 (which is the correct number). I use other queries based on the same tables/queries and changing these 2 properties makes no difference (always comes out to 29 records, as it should). So can someone explain what the diff between unique values and unique records is? I searched the Access 97 Help and its of No


Count of Unique Values in Access Field
In the query given below which is done in Access

[code]

The field Count([Q Test].[Contract ID]) lists the count of contract ids including duplicates.

What should I do to let Access Return only count of unique values. For example, there are 100 records having contract id out of which only 10 are unique, balance 90 are repetitions.

While currently access returns 100 for the field, I want access to return 10 which is unique values for the field.


Count Values in Totals for Reports
How does count values for totals in layout view work? I was hoping that it would count unique values in a column - but it does not appear to. I have an ID number column in my report - and the report is sorted by date. The same person/ID can have activity on several different dates. so they can have multiple rows in the report. I am trying to count each unique ID number in this report so I can provide a unique headcount for this report. I tried count values, and it gives me the same number as count records. Is there a way to count unique values in a column to show a total at the end of the report


Create Time Slots!!!!
in developing a column in query to create different time slots for each record like following:

IDs Time
new080592001 11:00 am
new080592002 11:00 am
new080592003 12:00 am
new080592004 12:00 am
new080592005 02:00 am
new080592006 02:00 pm

secondly how I can add unique values by developing append query .
For example I have developed a query which takes values from text boxes but those values are not unique in a table. The query append all values instead of providing unique values.
10-Oct-11 Ali Fayyaz
10-Oct-11 Ali Fayyaz
10-Oct-11 Ali Fayyaz

I want the query append only one record only instead of three records.


eCount to return a sum of unique values
I am attempting to do an eCount in Access to return a sum of unique values. I have 1257 records but I know through a physical count, I really only have 315 unique values.

In Column A, I know there are 36 unique Work_IDs - I need an eCount syntax that would provide this. Then, I need to count the Total number of Work_IDs where the Project Adoption Level only is 1 or 2; or the Assessment Status for the Work_ID is only Closed.


Putting Unique Query Results into Variables; VBA?
I have a query that returns unique values of one field. There can be from 1 to 10 unique values that are returned. Ex. 099 and 010 could return one day. And 002, 110, 956, 010, 099 could return another day.

I want to be able to put each returned value (however many) into an individual variable so I can use them in other queries I already have.

I tried DLookup() but it only returns the first value. And ELookup() wouldn't work for me


Count of Unique Values
In the query given below which is done in Access

SELECT [Q Test].[Lead Business], [Q Test].Region, Avg([Q Test].[Cycle time days]) AS [AvgOfCycle time days], Count([Q Test].[Contract ID]) AS [CountOfContract ID]
FROM [Q Test]
GROUP BY [Q Test].[Lead Business], [Q Test].Region;

The field Count([Q Test].[Contract ID]) lists the count of contract ids including duplicates.

What should I do to let Access Return only count of unique values. For example, there are 100 records having contract id out of which only 10 are unique, balance 90 are repetitions.

While currently access returns 100 for the field, I want access to return 10 which is unique values for the field


Understanding the Field and File Formats of Access 2007
One of the most unique changes in the newest version of Microsoft Access, Microsoft Access 2007, is the introduction of new field formats. Most database programs, including all previous versions of Access, allowed only a single value to be stored within each field, but Access 2007 allows users to store multiple values in each field, in effect creating a many to many relationship within the field itself, while hiding the details of the implementation using system tables.


Counting unique records in a column
I have a field that will have multiple records with repeating values (ie 6 records with "Adam74", 12 records with "Bryan67", etc), is there some way to count how many entries there are of each unique value and have it display in my form? This would have to update onstantly as additional values are entered and not be dependent upon a query for individual values.


Scatter Chart not Showing X-axis Values
I have a scatter chart in a form that I want to show Flow Rate versus Pf^2-Ps^2 in Access 2007. The Y values plot correctly in the chart, but X values just plot as 1, 2, 3 in succession. How can I get the X values to plot on the X-axis.

Prevent duplicate values in a field
You can prevent duplicate values in a field by creating a unique index. A unique index is an index that requires that each value of the indexed field is unique.
What do you want to do?
* Set a field's Indexed property to Yes (No duplicates)
* Create a unique index for a field by using a data-definition query

"You tried to execute a query that does not include the specified expression "unique Count" as part of an aggregate function"

Need help with Reports
I am using 2003 version and I am running into some issues.

I designed a form that allows my users to enter values. The values they enter are stored in a table. I have about 5 queries that do some calculations based on the values entered on the form.

I am trying to display the results of these queries on a report. On the main report I have 5 sub reports (1 for each query). When I run the report I want it to display values for each single row in the table.

For this I have set the criteria in the query to accept a unique value (for each row) from user so that it selects only the row with that unique column value but this is not working fine.
