Hi,
I am developing a windows application that needs to communicate with a remote SQL server 2005 database. Server allows remote connections and MSDTC service also running. Do I need to run MSDTC service on the client machine where I use desktop application ? any ideas ? It's throwing some error like
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. but my SQL server allows remote connections.

I was thinking it may be more of a case of needing MDAC on the clients.

Check wether all needed protocols are enabled in the SQL Server Configuration Manager.

You cannot use = NULL.
The previous post gave you the correct answer and it is important to understand what NULL actually means.
You cannot compare NULL to another value.
This is because NULL is an indeterminate value.
In other words NULL=NULL will always return false because NULL means the absence of a value.

I want to generate a script for tables and stored procedures using query analyzer.
for stored procedures i got it using -- sp_helptext spname
For tables how to do? using sp_help tablename -- giving structure of table and not generating a script. but i need script for this table using query analyzer
|
|
|
|
|
You need to use the correct tool. Use enterprise manager to generate scripts. It is designed for doing that, along with most other database design and maintenence tasks. Query Analyser is designed for only what it's name suggests.
.
|
|
|
|
|
In query analyzer press F8.
This should open a pane on the left where you can navigate via databases to tables and SPs.
From there right clicking on the SP or table should give you a menu with options to script the SP or table(Clicking on edit scripts SPs, I'm not sure about tables though).

Hi all ,
How is it possible to change the schema that a CLR Function/Stored Procedure/etc is deployed to? By Default , it is dbo.
Thanks in advance.
|
|
|
|
|
dbo is not the schema name, it is the owner name. It is an ALIAS that is always set to the currently connected user. If you are using integrated security then log on as the user that you want to own the resulting tables, sprocs, etc...

Your code is unnecessarily complicated and inefficient. SQL Server has had the ability to directly handle XML data since version 2000.
This article[^]explains how to use the OPENXML clause to pass XML data to a stored procedure.

yeah,I know that I did not optimize my code,but I do not think that it is complicated and unnecessarily .
Thanks for your advice ,can you tell me ,if I want use the openxml ,since version 2000,all have this function itself?
if you say yeah,I would be very happay, opposition,if need me install it,I do not think so!
and if anybody need my help,please give me message
my english is very bad!

You're wrong. It is. By using the OPENXML clause, you could have cut out most of your code. It's a core part of the T-SQL language. Read the documentation to learn how to use it.

Hi friends
I have one Table called tblCategory.
I have three Column CatID, CatName, ParentID
I have many records in this Table
CatID CatName ParentID
1 Cat1 0
2 Cat2 1
3 Cat3 1
4 Cat4 2
5 Cat5 2
6 Cat6 0
7 Cat7 6
8 Cat8 6
9 Cat9 7
10 Cat10 7
11 Cat11 8
Here I have Main Category which has ParentID 0 [ Cat1 and Cat6 ]
I Have Sub categories of Cat1 Which has ParentID 1(CatID 1 of Cat1) [ Cat2 and Cat 3 ]
Cat 2 has also sub category with ParentID 2 (CatID 2 of Cat2) [ Cat4 and Cat5]
I want result looks like as
Cat1 Cat6 ->>>>>ParentID 0
- Cat2 -Cat7 ->>>>>ParentID 1(CatID of Root Cat1) and ParentID 6(CatID of Root Cat6)
- - Cat4 - -Cat9 ->>>>>PaerntID 2(CatID of Root Cat2) and ParentID 7(CatID of Root Cat7)
- - Cat5 - -Cat10 ->>>>>PaerntID 2(CatID of Root Cat2) and ParentID 7(CatID of Root Cat7)
- Cat3 -Cat8 -->>>>>ParentID 1(CatID of Root Cat1) and ParentID 6(CatID of Root Cat6)
--No record --Cat11
Can anybody give me solution?
Thanks

try it !!!
declare @cid int
set @cid = 2
declare @S int
declare @E int
insert into temptblCategory
select *,-1 from tblCategory where parentId in(@cid)
select @E=count(cid) from temptblCategory where status=-1
set @S=1
while @S<=@E
begin
select top 1 @cid=cid from temptblCategory where status=-1
update temptblCategory set status=1 where cid=@cid
insert into temptblCategory
select *,-1 from tblCategory where parentId in(@cid)
select @E=count(cid) from temptblCategory where status=-1
end

Hi, assume I have two tables called Orders (ID, DateCreated) and a child table called OrderDetails (ID, OrderID, ProductID, Quantity)
What I need to do is calculate the average last 6 orders. Now if there are only 5 dates worth of orders I would need to know this value as I need to divide the sum(Quantity) by the number of orders - which cannot be greater than 6 previous orders. I have tried a few different select statements, but cannot seem to get the result I am looking for. Oh one other thing, I would be selecting these records by ProductID.
Any suggestions at all?
Thanks
|

|

I am not quite sure what you want your result set to look like. It would be easier if you gave a list of the resultant columns.
Are you looking for the last 6 orders of a particular product or simply the last 6 orders?

I need some help with a stored procedure, I have a table in my database that I am writing records to, specifically a BeginningDate field and EndingDate field. I want to be able to run a stored procedure that selects records based on a range of dates. This range of dates begins with monday and ends the following sunday, it covers an entire week. When I run the stored proc the where clause goes something like this:
<br />
select<br />
UserID,<br />
BeginningDate,<br />
EndingDate,<br />
<br />
From tableName<br />
<br />
where UserID = @UserID and BeginningDate >= @BeginDate and EndingDate <= @EndDate<br />
<br />
I know that it will not return any records if there is a date that is less than the EndDate. My question is how can I adjust this so it selects the one record based on a BeginDate and EndDate parameters?
|
|
|
|
|
select
UserID,
BeginningDate,
EndingDate,
From tableName
where UserID = @UserID and ((BeginningDate >= @BeginDate and EndingDate <= @EndDate) OR (BeginningDate >= @BeginDate) OR (EndingDate <= @EndDate))
Hope thats what you want ?

Hi, i have data like this in temp table
Owner - DocumentPath
1 - c:\reports\fileA
1 - c:\reports\fileB
1 - c:\reports\fileC
2 - c:\reports\temp\FileA
2 - c:\reports\fileA
2 - c:\reports\fileB
AND SO ON....
i would like to know...
Is it possible to concatenate all DocumentPath column's into single column for each Owner ?
so i would have a new temp table that looks like this (if possible... this is still theoretical)
Owner - DocumentPaths
1 - c:\reports\fileAc:\reports\fileBc:\reports\fileC
2 - c:\reports\temp\FileAc:\reports\fileAc:\reports\fileB
AND SO ON....
The reason i want to do this is because i need all the file paths in one line in one field on a report later... I thought i could PIVOT the data and then concatenate them...
OR
Is it possible to select only the top 3 (ordered by Modified Date DESCENDING) for each Owner???
like:
SELECT TOP 3 Owner, DocumentPath<br />
FROM #tempTableDocPath<br />
ORDER BY Owner ASC,Modified DESC<br />
BUT for each owner show top 3 (if they have three)
AND then Is it possible ONCE AGAIN to CONCATENATE the DocumentPath column into one column (in a new table / tempTable)?
like this:
Owner - DocumentPath
1 - c:\reports\fileAc:\reports\fileBc:\reports\fileC
2 - c:\reports\temp\FileAc:\reports\fileAc:\reports\fileB
AND SO ON....
Thank you in advance. I hope i put it all down clearly

Hi,
1. You can always write a stored procedure, wherein you can use cursor to concatenate the output of some SQL query. This string can then be returned / stored in some temporary table, which will be used later.

I didnt got this. Can you please clarify in details, what exactly you want in this case ??
