Access :: Copy Columns And Insert Them Again With Different ForeignKey?
May 8, 2010
I have a Access DB. I have relations with two tables. For example In my table1 I have three columns as T1ID, Name, Description and Tbale2 I have three column as T2ID, T1ID which is a foreignkey from Table1 and desc.
What I want is that : for example, I wanna copy the columns from table2 which has the value of 2 under the foreignkey field and I wanna insert them into table2 again with the value of 3 under the foreignkey field !

I'm using asp.net 2.0, vwd, sqlServer 2005, c#
After much researching I'm still @ a loss of how to do this.
I've looked @ scope_identity & @@identity but haven't been able to get it going...but I don't know if this is the command I should be using
I CAN: (from webform) insert data to Table2, ColumnA & ColumnB via stored procedure to db
I WANT TO:Insert the primary key of *Table1 to Table2 ColumnC so that it becomes the foreign key of Table2
*Table1 has data already displayed on the webform (used select command) & have class that contains the @ID_PK as Parameter

I have three tables in database:
ARTICLE with fields like ID_Article, Title, etc. and also a FK ID_Author
CATEGORY with fields ID_Category, Name
CATEGORYTOARTICLE with fields ID_Article, ID_Category
Now I have a page that shows all Articles of a given Category. Inside there is a GridView.
[Code]....
The ID of the viewed Category is passed via QueryString.
How to access the fields of Article table so that I can create columns for them in GridView? I tried using Eval("Article.Title") but it keeps saying that "DataBinding: 'konserwatyzm.db.CategoryToArticle' does not contain a property with the name 'Article'."

I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns()
{
// The first column to begin to insert the columns in the GridView
int columnIndex = 5;
BoundField aoColumn = new BoundField();
aoColumn.HeaderText = "New Column 1";
gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback
gvMyGrid.Columns.Add(aoColumn); // works fine
columnIndex++;
foreach (MyEntity my in _myEntityCollection)
{
BoundField myColumn = new BoundField();
myColumn.HeaderText = String.Format("{0:d}", my.StartDate);
gvMyGrid.Columns.Insert(columnIndex, myColumn);
columnIndex++;
}
}
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.

Some data, NULL, NULL, 2010, NULL
Some data, 2010, 2010, NULL, 2010
Some data, NULL, NULL, NULL, 2010
A new column needs to relfect 2010 for each row in the View.
Goal New View
Columns 1-10, FY_NEW
Some data, 2010
Some data, 2010
Some data, 2010, etc. for each row in the view
I can not hard code the data as time moves forward next year rows will have 2012, etc.

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

I have a number of tables that together make up a "Test" that somebody can take. There are multiple types (scripts) of Test a person can take. I'm working on an Edit function that will allow somebody to edit the Test Questions. I want these edited questions to show up on all new Tests of that type, but still show the old questions when viewing past test scores.
To do this each "Test" has a TestId auto-increment identity (along with its name). When a test is edited I want to make a copy of the test with a new TestId and present the questions for editing.
So what is the best way to make the copy and insert it into my table using LINQ to SQL? This:
DataContext db = new DataContext(ConnectionString);
//Copy old test into identical new test but with a different script ID
var oldScript = db.TestScripts.Single(ds => ds.TestScriptId == oldScriptID);
var newScript = oldScript;
db.TestScripts.InsertOnSubmit(newScript);
db.SubmitChanges();
of course tells me that I Cannot add an entity that already exists.
Is the only way to do this to go through every column in the TestScript and copy it manually, then insert it, and the database will give it a new Id?

Is there a way to copy a row from one table and insert to another but at the same time insert extra values to destination table?Let's say source table Item has values:
ItemID
ItemType
ItemProducer
ItemModel
Destination table ItemHist:
ItemID
ChangeDate
ChangeReason
ChangedBy
ItemType
ItemProducer
ItemModel
I want to copy row from source table where itemid is 25, insert it into destination table and add extra values: ChangeDate, ChangeReason, ChangedBy. I tried:
INSERT INTO ItemHist (ItemID, ChangeDate, ChangeReason, ChangedBy, ItemType, ItemModel) VALUES (ItemHist.ChangeDate=GetDate(), ItemHist.ChangeReason="why not", ItemHist.ChangedBy="me")
SELECT ItemID, ItemType, ItemProducer, ItemModel FROM Item WHERE ItemId=25
but obviously it didn't work ("The name 'ChangeDate' is not permitted in this context. Only constants, expressions, or variables allowed here. Column names are not permitted.").

Getting the message that ObjectDataSource ... count not find a non-generic method ... that has parameters ... The parameter list is fine until I get to the very end and it list the two data fields that are in my DetailsView. Using the ASP Tutorial #17 (Examining the Events Associated with Inserting, Updating, and Deleting) and the Exploring the Data Modification - specifically the one showing the INSERT of the Product Name and UnitPrice. ASPX page is pretty simple and attempting something similar, two fields to insert a new record - update the other fields later.
Full Error Message follows along with ASPX and the AsignaturasBLL.cs. Interesting thing is that when I swap the two fields in the DetailView, then the last two fields in the error message are swapped. In the error message I bolded these two fields.

I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.

I have a SQL Server 2000 table with 7 columns and would like to add a constraint that prevents a row being added with the same value for both Col2 and Col3.
So, for example, if Col2 = 205 and Col3 = 5, then the constraint should prevent inserting another row with the values for Col2 = 205 and Col3 = 5.
The following is an example of what I would like to prevent:
Col1 Col2 Col3 Col4 Col5 Col6
1 205 5 1 1 1
2 205 5 0 0 0

i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
