DataSource Controls :: TableAdapterManager.UpdateAll Shows Foreign Key Error When Insert Values To Master And Child Table

Mar 18, 2010

I am trying to use the TableApapterManager.UpdateAll to insert values to master and child table. I had set the relation to cascade for update in the dataset and the HierarchicalUpdate to true. But stil when I run TableApapterManager.UpdateAll(dataset), I get a foriegn key violation error. Following is the code I used:

int ID;
DAL.Datasets.dsMembers.MembersRow rwMem = m_dsMembers.Members.NewMembersRow();
rwMem.u_name = mem.Name;
m_dsMembers.Members.AddMembersRow(rwMem);
DAL.Datasets.dsMembers.MemPhonesRow rwmemphn = null;
rwmemphn = m_dsMembers.MemPhones.NewMemPhonesRow();
rwmemphn.u_memberid = ID;
rwmemphn.u_phn = "test";
m_dsMembers.MemPhones.AddMemPhonesRow(rwmemphn);
m_adpMgr.UpdateAll(m_dsMembers);
return ID;

The error I get is "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_MemPhones_Members". The conflict occurred in database "Family", table "dbo.Members", column 'i_memeberid'.
The statement has been terminated."

DataSource Controls :: Deleting All Child Record On The Base Of Primary Key And Foreign Key?

Apr 20, 2010

how can i retrieve the all foreign keys against a single primary key. i mean to say that if a table contain a primary key then it becomes as foreign keys in which tables.

i want to take that nam of that tables and on the base of that tables then i am to delete from all the entries. e.g: if a primary key's column entry deleted then all foreing key entries should also be deleted.

there are 988 tables in a single database. it can't be possible to go for each table to setup foreign key to ON DELETE CASCADE.

.can it have any way to delete against foreign key priority wise? mean to say that parent table contain primary key, child table contain foreign key , now there is another child table which dependent previous child table. then how can i delete all record against it?

i want to do it from programatically. i am using sql server 2005

i have completed this till to that , it retrieves all foreign keys but how to delete now on the base of priority.

DataSource Controls :: How To Create The Pivot Table To Search The Table

Feb 26, 2010

I'm assuming I need to use a pivot table from what I've found so far. However, every one that I've seen has not had the date setup like I have.

I have a Gridview on my page which I need to be populated like so

Date NCMR

1/1/10-1/31/10 #

2/1/10-2/28/10 #

I want to do this for 10 months... bottom record being the current month (or last month). I would also like the Date to format to January 2010 I used the above date format because that is how it is in the table. Basically, I need to know how to create the pivot table to search the table for 1/*/10, 2/*/10, etc

DataSource Controls :: Update Another Table Automatically As Row Entered In First Table?

Mar 1, 2010

I'm sure this has been answered many times already, but I still can't seem to find exactly how to search for this issue, so apologies in advance.

Anyway, I have a VB script for entering a row of data into a table by a web user. When this row of data is entered, I wish to take some of the values from the columns of the "primary" table, and have that data automatically create a new row of data in a "secondary" table. I think I'm part of the way there, here is my script:

[code]...

"ProductsByMfr" is the "primary" table - the table that the user adds data into when the button click event is fired.

"DealerPricing" is a "secondary" table that I wish to have some of the data from the newly-entered row in ProductsByMfr copied into. Am I even close here?

Sep 5, 2010

I have a table in my aspnet database. I added a bottom row "Not Selected", if the user doesn't select from a databound drop down list. This row is at the bottom, because I just added it to the table data. Is there any way to move this one row to the top of the table manually? There is not "cut" and "paste" when I select the whole row.

SQL Server :: Dropping Primary Key On A Table?

Mar 29, 2011

I am working on a database with about twenty tables. In one of the tables "Customers" their is a column with

a primary key. Call it "CustomerNumber".

The problem is that we log customers from multiple vendors and so we might have the same customer number, but from different vendors. So really this would be a perfect situation where we could set up the primary key to be a composite key consisting of the Vendor and CustomerNumber combination.

The integrity of the database is not very well maintained because the Primary Key CustomerId is never used as a secondary key in any of the other tables.

So here is my question. Instead of making a primary composite key, can I just drop the primary key all together?

This is one of those questions I really hate to ask, because typically I would never lean tword this drastic of a measure to solve a problem. Because of other situations I can't discuss this might be the best alternative. So would it be okay to drop the primary key constraint all together?

MVC :: Composite Primary Key + Editing Of A Table?

Feb 1, 2011

I have a table with composite primary key and this key includes two values referring to two other tables. Now I need to implement Edit feature for this Original Table but I wanted to have dropdown lists while editing pointing to look up tables(composite key values are primary keys for two lookup tables). for eg.

Table1(table1_primarykey, table1_field1)

Table2(table2_primarykey, table2_field1)

Table3( table1_primarykey,table2_primarykey, table3_field1) - composite primary key

while editing I wanted to display table1_field1, table2_field1 instead of original primary keys as numbers in Dropdowns.
