I mean its as easy for you to use the seach function on CP or google as it is for anyone else to do the search and send you the links. Its generally known as doing your own research, unfortunately it does not seem to be widely practiced judging by the majority of posts on these forums.

So first decide on what you actually mean. Do you want to know about data versioning in general, or in relation to a specific CMS product. If the latter, then check with the vendor. If it the former, what do you actually want to know, what it means or how to do it.
As I say, nobody can really help as you are not clear in your requirements.

I think you are trying to run before you can walk.

OK, so you need a good understanding of deltas etc associated with versioning
m-khansari wrote: I want to know it's approachs in general
Seems you don't much understanding about how it really works.
I suggest you google for methods of version control and learn from there.

Ca any I tell me the maximum number of input or output parameter a sql stored procedure can have?
|
|
|

In Books Online, the sql server help, search for "maximum capacity" - it will tell you the answer and loads more useful/interesting (boring?) bits of information.

Just a simple addin that does things locally. Not a full and sophisticated web solution or an addin that requires access to a webserver,etc..
I need to be able to add sort of Todo markers in my source code, and be able to easily get to the source code line. Just simple things, in order to manage things myself. not something for team work.
Thank you in advance.

How to unlock a table in sql server 2005? I tried killing the transaction which has a lock on the table by finding the spid through the sp “sp_lock” but still I’m not able to unlock the table.
A simple select query on this table with no “where” clause takes lot of time, resulting in Timeout Expired error. The table structure is also pretty simple with only one clustered index and the table has got only one record.
Please let me know what I can do in this scenario.
Thanks

Or you could use WITH(NOLOCK) if you just want to query the table.

The transaction has to rollback, so that takes as long (or even longer) than the transaction had been running when you killed it. Everything should go back to normal eventually, if not then you may have to restart the sql server instance.

You didn't mention the lock type on the locked row. If there is X lock present, you cannot select from that row (in normal situation). You'll have to wait that the X lock is gone or kill the transaction that's holding the lock (if it's not expected to hold it).
The problem you're facing may be a result of a transaction that isn't ended as it was supposed to (either rollback or commit).
Also you may want to read through the article I wrote.
The need to optimize rises from a bad design.

Dear Tiorio,
Since you were sorting on the basis of Parameter provided and it deals
with 3 columns of different data type that is why you were getting the error:
"Conversion failed when converting datetime from character string"
Just Convert the columns to Varchar will give you the desired results of yours.
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
-- =============================================
-- Author: <author,,name>
-- Create date:
-- Description: <description,,>
-- =============================================
ALTER PROCEDURE [dbo].[GetPurchaseOrders]
-- Add the parameters for the stored procedure here
(
@Order_no bigint,
@VendorId int,
@FromDate datetime,
@ToDate datetime,
@Sort_by varchar(15),
@Sort_order varchar(15)
)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SELECT p.Order_No as OrderNo,v.Vendor_Name as [Vendor], Order_date as OrderDate
from
Purchase p
join
Vendor as v
on p.Vendor_ID=v.Vendor_ID
where p.Order_No= COALESCE(@Order_no,p.Order_No) And
p.Vendor_id = COALESCE(@VendorId , p.Vendor_id ) And p.delivered='N'
ORDER BY
CASE @Sort_by
WHEN 'Order No' THEN CONVERT(VARCHAR, p.ORDER_NO)
WHEN 'Date' THEN CONVERT(VARCHAR, p.order_date) WHEN 'Vendor' THEN v.Vendor_Name
END desc
end
Hope this answers your question.
Thanks and Regards,

Looks like it may be coming from the Order_date field. Is that field's datatype datetime or a character type?

Hey Guys,
Here is my issue -
I have a table with 3 date fields. (Entry Date, Pending Date, Accounting Date) -> in my GridView I need to represent this value in 1 column called (Report Date). My rules are if Accounting Date is null use Finalized Date, if Pending date is null use Entry Date. This rule has to work on a row by row basis as I am returning 100's of rows.
Now if this is better done in the code - I can do that also.
Any help would greatly be appreciated.
Thank you.

Well, depending on whether or not your DBMS supports it, you could use the CASE statement to accomplish this, or you could use a COALESCE method,e.g.
SELECT COALESCE(AccountingDate, PendingDate, EntryDate) AS RuleDate ... This assumes that one of these columns has a date value in it. Basically, coalesce falls through from one entry to the next until it finds a none-null value. BTW - I'm assuming that you got your logic a bit wrong in your statement and you mean Pending Date and not Finalized Date.

|
|

CASE WHEN Accounting Date IS NULL THEN Finalized Date WHEN Pending date IS NULL THEN Entry Date END
etc.
