From VS 2005 documentation:
DataAdapter.Update - Calls the respective INSERT, UPDATE, or DELETE statements for each inserted, updated, or deleted row in the specified DataSet from a DataTable named "Table."

Thanks for your reply. "DataAdapter.Update" is for updating a DataTable in DataSet. I want to know how to insert this updated data back to SQL.

Try this snippet and let me know if it worked for you.
SqlConnection c = new SqlConnection(@"Data Source=(local)\SQL2005;Initial Catalog=TEST_DB;Integrated Security=True");<br />
SqlDataAdapter da = new SqlDataAdapter("select * from customer where customer_id = 1", c);<br />
SqlCommandBuilder cb = new SqlCommandBuilder(da);<br />
DataTable dt = new DataTable();<br />
<br />
da.Fill(dt);<br />
dt.Rows[0]["NAME"] = dt.Rows[0]["NAME"].ToString() + "1";<br />
da.Update(dt);

Hi
I have problem in getting primary and foreign key for a given table.
For example in a Adventureworks Database, Production.ProductCostHistory table.
If i try to get the foreign key related table it is not returning any value.
But ProductID is is both primary and foreign key.
How to get the foreign key table for the given table.
sp_fkeys not working if it is a composite key.
exec sp_fkeys @PKTable_name='ProductCostHistory',@PKTable_Owner='Production'
Can any one help me please?........

If you have the correct rights you can select your table from sysobjects where [name] = 'yourtablename'
You can use the id from that table to look in sysindexes for your primary keys.
Then you can look in sysforeignkeys to see if you have some foreignkeys
Hope that helps.

It is not that easy.
First if you look in the sysobjects table for your table name to get the id.
Next if you look in the sysobjects table for an xtype = 'PK' that is a primary key that has a parent_obj = the id you found above. This gives you your primary key
Next you look in the sysforeignkeys table using the parentid
joined back to sysobjects to try and find a foreignkey if it exists.
So if you have a customer table and a customertype table
Customer Table:
customerId
CustomertypeId
... other stuff
CustomerType Table:
customertypeId
... other stuff
Here's a query:
declare @id int
select @id = id from sysobjects where [name] = 'customertype'
select * from sysobjects where xtype = 'pk' and parent_obj = @id
select * from sysforeignkeys fk
join sysobjects so on fk.fkeyid = so.parent_obj and so.xtype = 'f'
where fk.rkeyid = @id
I don't know if that helps at all it is quite complicated.

Thanks a lot ben
I have done this by following way
Select Tab1.Column_name,(select Schema_name(uid) from sys.sysobjects where id=PK_table_id)+'.'+Tab2.PKtable_name as PKTable_name, Tab2.PKColumn_name, Tab1.Table_Schema+'.'+Tab2.FKTable_Name as FKTable_Name, Tab2.FKColumn_Name from (Select Column_Name, Data_Type, Table_Schema from Information_schema.columns where Table_Name='Product' and Table_Schema='Production') Tab1 left outer join (select PKColumn_Name=c1.name,PKTable_Name=Convert(Sysname,Object_Name(f.refereced_Object_id)),PKTable_ID=f.referenced_Object_id,FKTable_Name=o1.name,FKColumn_Name=c2.name from sys.all_objects o1, sys.all_objects o2, sys.all_columns c1, sys.all_column c2, sys.foreign_keys f inner join sys.foreign_key_column k on(k.constraint_object_id=f.object_id) inner join sys.indexes i on (f.referenced_object_id=i.object_id and f.key_index_id=i.index_id) where o1.object_id=f.parent_object_id and o1.object_id=object_id('production.product') and o2.object_id=f.parent_object_id and c1.object_id=f.referenced_object_id and c2.object_id=f.parent_object_id and c1.column_id=k.referenced_column_id and c2.column_id=k.parent_column_id) Tab2 on Tab1.Column_name=Tab2.FKColumn_name

You can do. Off the top of my head the regular expression would be something like
^[0-9]*$
NOTE: This accepts only positive integers only.

I have a column in my database called SaleNumber which has a datatype numeric(18,0). One of the values I have stored in there is 11101930593 however when I retrieve this value from the database in my delphi application the number displayed is -1782971295.
Does anybody know what could possibly be going on here?

I don't know Delphi so this could be way off the mark. I'm guessing that it might be an overflow. Are you putting the column value in a 32bit integer? A 32bit integer has a range of rougly -2billion to +2billion. Your number is roughly 11 billion.
|
|
|
|
|
No I am parsing it in as an unsigned long.
|

It looks like Colin is right. You tried, somewhere along the line, to stuff a 64-bit number into a signed 32-bit variable. What you're seeing is a sure sign of an overflowed signed 32-bit value.
Step through your code and verify that the value you got from the database is what you expect, the instant you get that value. Then follow it from there. Perhaps the value IS an unsigned 64-bit value, but when you went to display it, it got truncated to a signed 32-bits.

When I try to set up an email subscription for SSRS 2000, I get:
EXECUTE permission denied on object 'sp_add_category', database 'msdb', owner 'dbo'.
The dbo user for the msdb has admin priviledges. I'm stumped on what to do or look for.
Found this in the catalog.sql file:
GRANT EXECUTE ON msdb.dbo.sp_add_category TO RSExecRole
I ran this script for the msdb database via Query Analyzer, tried the subscription again, and got:
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help EXECUTE permission denied on object 'sp_add_category', database 'msdb', owner 'dbo'.
We're connecting to the db server from a shared datasource w/ a user, let's say "reportuser", that has only "Read Access" to pull the data.
Any suggestions? Thanks!
