I could if I wanted to, but it doesn't help. The problem is that once the SQL server is reporting to be started to the SCM, it still hasn't made all databases online yet (only the master database is available). That work progresses after the SCM has been signalled that the service is running.
I found the solution to be easier than I thought. All I have to do is to
SELECT COUNT(*) FROM sys.databases WHERE name=@database_name AND state_desc='online' and see if it returns 0 or 1. Once the database manager reports the database as online, it is possible to use the database.

Okay, I'm new here and to programming in general. I don't want to waste a lot of your time as I know the question I have has probably been asked before. I'm just not sure what to search for.
What I'm trying to do is create a site that displays a list of products from a database (which I know how to do) and when you click on the item it displays the product details (which is where I'm stuck). I've built a static html site at here so that you can get an idea of what I'm going for. As you can see there's quite an extensive description of the product which I haven't seen discussed how to create pulling from a database.
Any help would be greatly appreciated. Like I said, I know this has probably been discussed, so all I'm asking for is a point in the right direction. I'm not sure what I should be searching for. Thanks for your help in advance.
Also, I guess I should let you know that I know html and I know the basics of asp.net (c#). And I'm using Visual Studios 2008.
Again Thank You.

Well you got the wrong forum on your first attempt, the ASP forum will give you better results.
Here is a little Goole mojo[^] to get you started, the first result may be useful. There is a basic ASP tutorial around the demonstrates loading a grid and then using a details block to manage the CRUD on an item, that sounds like what you are after (sorry no link).

Sorry, I wasn't sure where to post since half of what I'm looking for is setting up the database for the product page and the other half is displaying it on the page. I looked at that link and I already know how to set that up. It's when links are clicked and I need a product page with 4-8 descriptions of the product that has me stumped. I guess I'll ask this over at the asp.net section. Thanks for your help.

Hi,
I am trying to insert into a DateTime field by concatenating a string and a nVarChar field like so:
CONVERT(datetime, '1/1/' + tblMembershipRecords.[YearJoined], 103)
But I get a message stating;
'Conversion failed when converting datetime from character string.'
Any ideas what is going wrong?

The computer tries to "interpret" your string as a date, and it doesn't understand it. It seems that it expects the date to be in a different format.
Try something like this;
SELECT DATEADD(y, tblMembershipRecords.[YearJoined], getdate()) That will add a single year to the DateTime, without converting it to a string.

Good Day all
it is Probably a long day, i cant think Straight now.
i have a table that looks like this
Nodeid Parent Description Type Curr
==========================================================================================
89 NULL Compulsory 1 10
90 89 B1052 3 10
2820 89 One of 2 10
4113 89 B1061 3 10
2821 2820 B1054 3 10
2822 2820 B1055 3 10
Now the Bold Record needs to be on top of "One of" because the Parent is "Compulsary" with the "Parent" = 89. Now Even "One of " has the Same Parent as the Bold record but if its a "One of " and they have the same parent, then "One of " must always be below the record. What i mean is that if there is a record with a same parent but different Type , the one that has type 2 should go below the one that has type 3 in my query. here is my query
select distinct nP.id, nP.NodeID, nP.parent, nP.Description, nRef.ID refParent, np.type
from #Nodes nP
left outer join #Nodes nRef on nP.Parent = nRef.NodeID -- look up the reference id of the parent
order by refParent,nP.id,np.type desc
Thank you

Thanks now i have Changed my Code to look like this and its working perfect in SQl when i test it.
select distinct nP.id, nP.NodeID, nP.parent, nP.Description, nRef.ID refParent, np.type
from #Nodes nP
left outer join #Nodes nRef on nP.Parent = nRef.NodeID -- look up the reference id of the parent
order by np.Parent,np.Description,np.NodeID
And it returns
Nodeid Parent Description Type Curr
==========================================================================================
89 NULL Compulsory 1 10
90 89 B1052 3 10
4113 89 B1061 3 10
2820 89 One of 2 10
2821 2820 B1054 3 10
2822 2820 B1055 3 10
and its Good thanks.
am binding the values to a Tree Control like this
public void PopulateTreeFromCurr(int currID)
{
IEnumerable result = CurrStructDataSource.Select(DataSourceSelectArguments.Empty);
int Parent, Child;
CurriculumTreeView.Nodes.Clear();
ArrayList CurrNodes = new ArrayList();
if (result != null)
{
foreach (System.Data.DataRowView row in result)
{
TreeNode newnode = new TreeNode(row["Description"].ToString(), row["NodeID"].ToString());
CurrNodes.Add(newnode);
if (row["refParent"].ToString() == "")
{
}
else
{
Parent = Convert.ToInt32(row["Parent"]);
Child = Convert.ToInt32(row["ID"]);
TreeNode ParentNode = new TreeNode();
TreeNode ChildNode = new TreeNode();
[COLOR="DarkOrange"][B]ParentNode = (TreeNode)CurrNodes[Parent];[/B][/COLOR]
ChildNode = (TreeNode)CurrNodes[Child];
ParentNode.ChildNodes.Add(ChildNode);
CurrNodes[Parent] = ParentNode;
}
}
if (CurrNodes.Count > 0)
{
CurriculumTreeView.Nodes.Add((TreeNode)CurrNodes[0]);
CurriculumTreeView.ExpandAll();
}
}
}
in the code i get an Error in the bolded red part line
ParentNode = (TreeNode)CurrNodes[Parent];
and it says
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Thank you

select ROW_NUMBER() OVER (ORDER BY pid DESC) as RowNum, pid,grpname from
(select distinct p.ParticipantId as pid,p.pname + ' (' + p.username + ' )' as grpname from
TSParticipants as p inner join TSGroupParticipants as gr
on p.ParticipantId=gr.ParticipantId
where p.status=0) as grplist
in the above query i have to add the the below where condition
WHERE RowNum BETWEEN 0 AND 0 + 6 -1
where should i add this condition
if add it its showing error:
Msg 207, Level 16, State 1, Line 8
Invalid column name 'RowNum'.
Msg 207, Level 16, State 1, Line 8
Invalid column name 'RowNum'.
--------------------------------
select * from
( select *, row_number() over (unique_column_name order by asc) as rownum from emp ) as test where rownum between 0 and 0 + 6 -1
-----
this above query gives all the rows
i need only unique rows

I have created a sample example. Hope this may help you.
declare @tbl table(firstname varchar(50),lastname varchar(50))
insert into @tbl
select 'firstname' + CONVERT(varchar(50),column_id)
,'lastname' + CONVERT(varchar(50),column_id)
from sys.columns
select * from @tbl
select firstname,lastname from
(select ROW_NUMBER() over(order by firstname) as rn,firstname,lastname
from
(
select
distinct(firstname),lastname
from @tbl t
)X(firstname,lastname))Y(rn,firstname,lastname)
where rn between 0 and 0 + 6 -1
As per the understanding I made after going thru ur statement, I thought that u r looking for unique records. Henceforth, in the very beginning only I have used a distinct clause.
Note:- I tried to explain the concept. You need to customise and implement as per ur requirement.
Let me know in case of any concern.
I cannot make out why instead of using 5 directly u are using 0+6-1?

It seems fairly obvious, add a size
sql_command.Parameters.Add("@banner_file", SqlDbType.VarChar, 255);
only two letters away from being an asset

Hi.
I just wanted to let you know that db4o has improved its memory manager making it more appealing to .NET & Java developers who work in memory constrained environments. In memory usage of db4o is now more closely integrated with the storage API which removes redundancies while bringing better support for administrative features such as defragment and backup. The new PagingMemoryStorage implementation significantly reduces memory footprint.
More info:

Best!

Hi,
Which method is the best way to transfer realtime data from one sqlserver to another sqlserver.
Plz let me know..
Thanx...

If you are using 2005 or greater then you should look at Sql Server Service Broker as it was designed specifically for your requirement.
|
|
|
|
|
Do you mean transfer or replicate? For the former, assuming sql server 2005 or later, useService Broker, for the latter google replication.

I have an Access database which contains every date between 01/01/2009 and 21/12/2029. In a 2nd column is a char value indicating whether the date is a working day or not. I need to decide whether xmas & boxing day fall on a non-working day and if so adjust the working day column value. I have the following to calculate the adjusted dates:
SELECT switch((DATEPART("w",FullDate,2) In (6,7)),DATEADD("d",+2,FullDate),(DATEPART("w",FullDate,2) Not In (6,7)),FullDate)
FROM UKWorkingDays
WHERE DATEPART("m",FullDate,2)=12 And DATEPART("d",FullDate,2) In (25,26);
If I wrap this in an update statement the SQL appears to execute but does nothing at all
UPDATE UKWorkingDays SET WorkingDay = "B"
WHERE FullDate in
(
SELECT switch((DATEPART("w",FullDate,2) In (6,7)),DATEADD("d",+2,FullDate),(DATEPART("w",FullDate,2) Not In (6,7)),FullDate)
FROM UKWorkingDays
WHERE DATEPART("m",FullDate,2)=12 And DATEPART("d",FullDate,2) In (25,26)
);
Can anyone give me any assistance please ?

|
|
|

Ew Access again - and a newer version than I have worked with. Some thoughts.
Why do you have the switch (what is switch doing in SQL code) in the select portion, surely you want that in the where clause.
Select Fulldate
From UKWorkingDays
Where fulldate in (filter 25/6) and weekday in (filter weekdays)
I leave it to to grasshopper to fix the filter.

Thanks for the reply Mycroft but I'm not sure that it is of much help.
Take this year for example. 25/12 is a Friday, 26/12 is a Saturday so 28/12 is actually a holiday not a working day. My inner select statement returns 2 rows correctly containing Friday 25/12 and Monday 28/12. I then have to check every row in the table against these returned values and if equal mark the date as a non-working day (my outer update). The inner select works a treat so I thought an update statement where date in (inner select) would achieve what I wanted but for some reason it appears to do nothing, no rows returned updated and no exception thrown. Maybe its looping too many times and would eventually finish. I'll have to re-visit my code and see if there's a better way.

More on this..
I've just stripped out all but this years dates and run my query which has done exactly as I expected and updated 25 & 28/12. I guess its just baulking at the number of repetitions it has to perform on the full table so I'm on the right track but do need to improve the code.
