I am very new to MS Access and I don't even know how should I start to approach for the solution.
I have a Table 1, that contains Project No., Part No. and Quantity of parts.
Now I want to transfer this data on button click to two different tables.
Table Order and Table Parts.
Table parts is a sub table of Table Orders
When we add project Number to table Orders, then we get auto-generated ID then based on that Unique ID, Table Parts is linked to it.
As we get ID from Table Orders, we need to create entry into table Parts with that ID that will contain Part Number and Quantity.
Can you please help me this?
I tried creating an append query but its just adding Project to Table Orders, not doing anything with Part No. and Quantity.
It must be very easy, baut i can't display a very simple filtered agregation on a table header row in BIRT 3.7. I manage to use count aggregation on groups headers or footers, buet not a filtered aggregation on a simple column table.
USE case : my sql statement car return the string value "ERROR..." for a string field name TEST. The query returns 734 results. My table display all the results.
In the header row i just want to diplay a count of which would be in SQL a count like "ERROR%".
I can't manage to do that whit the aggregation tool !
aggregation builder
Many thanks for your help.

as i can't manage to find the correct way of filtering my aggregation, i provide the results from my SQL request. By i'd be glad to find the dynamic way of filtering it.
Here is an image of a column that contains strings with "ERR". Le top field in red is my aggregation field served by a slq like '%ERR :%' statement.
example
I am using SQL Server. I have 2 columns Passed students and Failed Students in my database.
How to write a query which displays both these columns along with a third column which is Total Students which displays the sum of the entries in the row?
EDIT
It is not allowing me to ask another question.So,posting it here:
I have a hyperlink field in my gridview as below:
[Please refer comment for the code.For some reason it doesn't get posted here.]
Its basically a runId.When I click on this hyperlink I am redirected to a page called RunAnalysis.I want to access the value of the runId which was clicked in this page.
I was thinking of using query string but there is no event as far as I know that is fired on click of the hyperlink.
My question is how do I access the runId value in this page ? Can someone tell me if some event is fired so that I can send a query string.
Thanks.
You haven't given a lot of background information so I am assuming many things in my response.
Here is a simple aggregated result set:
SELECT SUM(Passed) AS [Passed],SUM(Failed) AS [Failed],COUNT(*) AS [TotalStudents]
FROM dbo.Students
Now if there is some grouping you want to do then you would add a GROUP BY clause like so...
I'm creating a new column because I don't know your schema:
SELECT GradeLevel, SUM(Passed) AS [Passed],SUM(Failed) AS [Failed],COUNT(*) AS [TotalStudents]
FROM dbo.Students
GROUP BY GradeLevel
ORDER BY GradeLevel
I am making a table by combining columns of two tables. But there are few duplicate rows also. How do you delete duplicate rows from MS Access. I tried using the duplicate record query and also tried to use append query. But neither of them worked.
There are a couple of ways you can do this without using the Access wizards:
1. Run a Make Table Query and in the select statement use grouping for every column. If the tables have a unique ID, don't use the ID because that will make every record unique
2. Export a Select query with the columns you want from the two tables to an Excel workbook. Once in Excel go to the Data tab and click on the column header selector and click on the Remove Duplicates button. Make sure you expand the selection if it asks you. Then save and link the Excel Workbook to Access again and do whatever you need to do from there
There are more ways, but you'd have to provide more details as to what you're trying to accomplish
Using the ASP.NET grid view. It displays 3 columns with 1 row for each, displaying an integer saved in the database. I would like to have a text input one for each column, so the user can add a new row of integers to the database. (The table only displays the last row updated, that part seems to be working OK)
Here is the code I have that displays data but without the input option I would like.
What is the way this is done in ASP.NET (3.5)? Are there more options in the control or do I need to manually bring in text input controls and give each one manual code to update the database? Any help is appreciated.
Thank You.
Do you know the asp.net website? There are a lot of tutorials, e.g. about data access. You might find the information you need, e.g An Overview of Inserting, Updating, and Deleting Data.
Also check out the ASP.NET Dynamic Data section on the same page.
