I try to be helpful, but after 12 hours and no response to my request for clarification I can see that it isn't really that urgent.

The original post must not be really that urgent after all. Putting in "urgent" must have just been bait to get someone to reply right away.

matched wrote: when i try to complie vs 2005 gives me some crap error which i dunno what does it means (The column mapping from SourceColumn 'Total' failed because the DataColumn 'Total' is a computed column)
That doesn't read like a compiler error to me. The compiler doesn't know anything more about DataSets, DataRows and DataColumns beyond the fact they are classes - so a high level error that indicates semantic knowledge of the classes it is using is virtually impossible to come from the compiler. I can't actually see how the compiler could pick up on this error as the fact that "Total" is computed can't really be known until run time.
So, where did this dataset come from? How was it created? What filled it and with what?

There are enough forum guidelines around the world that you must have picked up on one or two of them... Curiously, the all say very similar things.

Hi
I have the following questions with regards to drag-drop type of databinding in windows forms.
Platform:
windows forms data bound form with the database as a source...
Bound column is defined as Identity in target SQL Server database
The databinding is created by draging-droping the datasource
Binding Navigator is automatically created
Senario:
When clicking the "BindingNavigatorAddNewItem" (the one with +) the bound text field to the identity column is incremented by 1.
Qustions:
Q1 - Is there a row added after to the underlying datatable after the click? Is the row added to the datatable only when you press the save button?
Q2 - Where is the code that increments this value?
Q3 - How to control the process of incrementing the value and showing it on the textbox? For example, I tried to create an event handler for this button but as soon as the code gets to this handler, the increment would have been completed already.
I have also tried to use the BindingSource.CancelEdit() but that did not work either.
Thanks for your help.

Hi,
I'm looking for some advice on a problem:
Mobile application implementing AUTD (http://msdn2.microsoft.com/en-us/library/aa446486.aspx[^]) calls a webservice. This webservice polls a SQL server (2005) every 30 seconds, for at most 3 minutes, lookikng for changes. Once the webservice has detected a change it returns true otherwise false. If true the mobile application makes another request to retrieve the changes, otherwise it issues a call to the webservice to check for changes.
The problem is that I would like a better way of checking SQL server for changes - some kind of event driven approach. I have tried using the Service Broker, based on http://www.codeproject.com/useritems/SQLNotificationRequest.asp?df=100&forumid=399750&exp=0&select=2062673[^]. However timing out the web method was impossible. I left the method running for an hour and it still responded to a change in a SQL table!!!!! The command timeout was set to 10 seconds.
Any help/suggestions would be greatly appreciated,
Mark

We are redoing our database. We have in an excel spreadsheet the mapping from the old to
the new: old table name, old column names, new table name, new column names. Is there a
tool out there or code that someone has put together that will create a new procedure from
the old replacing the old table names and old column names with the new table names and
new column names?

I suppose is a typical query but I dont know if exists a query to solve the next. Take for instance:
1.- Table items:
Code|Name
1000 Apple
1001 Orange
1002 Banana
2.- Table prices
Shop|Code|Price
1 1000 1.33
2 1000 1.44
1 1001 1.90
2 1001 2.10...
Can I show in a SQL query something LIKE:
Code Name PriceShop1 PriceShop2
1000 Apple 1.33 1.44
1001 Orange 1.90 2.10....
Thanks for any help because Im getting crazy

If you just have 2 shops then:
select i.Code, i.Name, p1.Price as PriceShop1, p2.Price as PriceShop2
from Items i
left outer join Prices as p1
on p1.Code = i.Code
and p1.Shop = 1
left outer join Prices as p2
on p2.Code = i.Code
and p2.Shop = 2
order by i.Code This links to the Prices table twice (one for shop 1 and once for shop 2). The "p1" and "p2" bits are "alias" names for these joins.
If you have more shops then you should try searching google for "crosstab queries".

If you are in SQL2005 you should look at the PIVOT command.

Hi All
i have a table with data to send it to the other Department. and when the bring back this table, it will come back with more additional Fields.the others Fields that were present in that table, i dont want them to be tempered with. So i want a way to validate or check if there was anything change from the table. i want to check based on two Fields. am using SQL2000. i need something like a Match. to match two tables.
Table 1 Table 2
============ =========
Num_key Num_key
Lis_key Lis_key
i want to check if the value i have sent to the other Department, did not change.
Thanks

I'm not sure what you are trying to do. Do you want to find the records in Table 2 that are not present in Table 1? If so, use the following query:
SELECT Num_key, Lis_key
FROM [Table 2]
WHERE NOT EXISTS
(SELECT TOP 1 *
FROM [Table 1]
WHERE Num_key = [Table 2].Num_key
AND Lis_key = [Table 2].Lis_key)

HI Paul
Thanks for the Reply
what am trying to achieve is the Following.
i have Table 1, that has records, and i want to send it to the other Department. after sending it, i will keep the copy of table1. when a Copy of Table1 has return from the Department i have sent too, it will have more additional Fields with it. i will now call it "Table2", now remember,that the same fields are still in Table 2 but with more addition. Now i want to Compare the Fields in Table1 And Table 2, only on the records i have sent to the Department, if they have changed in a Field ="Lis_key" and "Attrib_code".
i hope i have Explained it well this time
Thanks again

Is there a primary key on this table?
|
|
|
|
|
Yes there is a Primary key,
When i sent the table to the Other Department the Primary key was a field ("Property_ID") , and now because there are some records that i did not send to the department that will be present when table 2 returns. so i deciced to accept table2 and add a primary key to it as (Primary_ID). that means Table1 Primary key will be (Property_ID) and table2 will be Primary_ID. and the Field Property_ID will still be present in table2 but it will not be a primary key anymore.
Thanks
