Why The Sum Of Node_distribution.support Value Is Not Equal To The Value Of Node_suport For A Specific Node?

Dec 5, 2006

Hi, all here,

Thank you very much for your kind attention.

Just noticed that the sum of node_distribution.support value is not equal to the value of node_support for a specific node in my Microsoft Clustering Algorithm Model? If so, how can I correctly count the distribution of each attribute value among all?

Really confused.

And thank you very much in advance for any guidance and advices for that. Looking forward to hearing from you shortly.

With best regards,

Yours sincerely,

Updating Specific Columns If That Column Is Equal To A Value In One Query?

Dec 8, 2006

I want to set a column to 0 if it is set to a certain number. There are several columns to check though, so I am wondering if I can do it all in one query, or if I have to do it in single queries?

here is an example:

account | contact_id_1 | contact_id_2 | contact_id_3
433 | 67 | 23 | 67

so I want to set any contact_id_N = 0 where contact_id_N is = 67

so in the end, the table will look like this:

account | contact_id_1 | contact_id_2 | contact_id_3
433 | 0 | 23 | 0

is there a way to do it in one statement?

How To Show Two Dataset With Equal && Non Equal Of Multiple Selection.

Jun 14, 2006

Dear Friends,

In my report, I am having Listbox for users to choose Country, City & Company.
The user can choose Country. Based on the country selection, cities will be listed out.
Based on the city selection, Companies will be listed out.
They can choose companies.

Now, I have to show two set of results.

A. List of Companies as per selection ( dataset with equal to selection )

B. List of Companies which are not selected ( ie dataset with not equal to selection )

I have created a dataset with all companies and filter it by selection. When I tried with the filter option in the Dataset, I am able to check for only one value and not for multiple value. If the selection is one company, then I can filter it. But if they choose 5 companies, I am not not able to filter it. Is there any other option I can try out.


Please advice. Thanks.

warm regards
Rakin

Getting The Schema Rowset And Subrows Of Node_distribution

Jan 9, 2008



Well, i need a piece of code that return me the schema rowset of a desicion tree and let me iterate me on it. I need some columns like node_type, node_unique_name.... etc.. And another question is that the node_distribution has multiple rows of information. How can i access them. I think there must be a adomddatareader object to iterate on them..

Well thanks a lot for your responses...

Why The Node_distribution.PROBABILITY Greater Than 1 In Clustering Algorithm?

Nov 24, 2006

Hi, all experts here,

Thank you very much for your kind attention.

I am having a question about the node_distribution.PRABABILITY. Some of the attribute values though have a small number of support for the specific node, but why it has a big node_distribution.probability even greater than 1? How can the node_distribution.PROBABILITY be greater than 1? How dose SQL Server 2005 data mining engine calculate the node_distribution.PRPBABILITY for its Clustering algorithm? Really confused and need guidance for that.

Thank you very much for your help.

With best regards,

Yours sincerely,

SQL 2012 :: Log Shipping - Reboot Secondary Node And Then Primary Node

Apr 20, 2015

I have not used log shipping before and find myself in a position where I need to reboot the secondary node and then the primary node and I don't actually need to failover.

Is there anything I need to be aware of. When rebooting the secondary node I assume the transactions will be held in the primary nodes log till the secondary comes back and just carry on once back up?

When rebooting the primary node nothing needs to be done and the log shipping will just start again once it has come back?

Do I Need To Install SQL Server To Second Node In Cluster Prior To Adding The Node?

Jun 12, 2007

I read these instructions:

http://msdn2.microsoft.com/en-us/library/ms191545(SQL.90).aspx



But I'm not sure if I have to install SQL Server first on node 2, then add it to the cluster. Or does adding it to the cluster also install the software?



Thanks

SQL 2012 :: Running 2 Distinct AGs On Each Node Of A Two Node Cluster?

Oct 23, 2014

I'm contemplating running two availability groups on a two node WSFC. The WSFC is setup with a file share witness (i.e. no shared storage). Can I safely run 1 AG on one primary node, and the other AG on the other node (as primary). Each AG would have replicas on the passive node. This would effectively allow both servers to be in use at the same time. In a failover event, I understand that both workloads would transfer to a single server - so the box needs to be sized appropriately.

SQL 2012 :: 3 Node Cluster Runs With 2 Node Failures?

Jun 11, 2015

We are in the process of building a 3 node SQL Server Cluster (Server 2012/ SQL Server 2012), and we have configured the quorum so that all 3 nodes have a vote (no file share witness as we already have an odd number of nodes).

As I understand it, this should allow the cluster to run as long as 2 of the nodes remain online.

However, the validation report states that 2 node failures would be acceptable and, when we tested this by powering off two of the nodes, the cluster did indeed continue to run on a single node.

How Do You Determine The Active Node Inside A Stored Proc For An Active/passive 2-node Cluster?

Jan 16, 2008

I invoke xp_cmdshell proc from inside a stored procedure on a 2-node active/passive SQL 2005 SP2 Standard cluster. Depending on which server the xp_cmdshell gets executed on I need to pass different arguments in the shell command. I thought I could use host_name() function to get the runtime process server, however, I am finding that it's not behaving correctly. In one example I know my active node is server2, but the host_name() function is returning server1. The only thing that I could possible explain this is that the MSDTC cluster group is not always on the same active node as the SQL server group and in the case I am talking about the cluster groups are in this mode (differnet nodes). Does the xp_cmdshell get executed by the SQL active node or the MDTC active node? And what is the best way to find out which server is going to run my xp_cmdshell?

Thanks.

Edit:

Perhaps another by product of this is that if I run select host_name() from the Studio Management query window i get different results depending on which server I am running the Studio Management on. On server1 I get server1 and on server 2 I get server 2, all the while server2 is the active node. I need a different function that will always let me determine the correct server that'll be running the xp_cmdshell...

Edit 2: I guess I could determine the running host inside the command shell itself, but I am curious to see if i can do it (cleaner) from SQL.

Support For SQL Express2005 My Host Provider Does Not Provide Support?

Dec 5, 2005

Reader Community
I've just started hosting my newly created Microsoft Visual Web Developer 2005 Express Edition web site.  Unfortunately the Login group membership functions will not function correctly.  Having contacted the web service hosting provider, They replied: "We do not support SQL express2005.  The only way to use the extra functions of ASP.NET2 such as group membership is if it is using an SQL 2000 database to connect to. "
Is it possible to design web sites with Microsoft Visual Web Developer 2005 Express Edition that store membership details on an SQL 2000 database?
I've just paid £88 approx. $140 for a years subscription, have I chosen the wrong web service hosting provider?
Should I have designed the web site with a better web site design software tool that also makes designing membership login functionality easy, just as Microsoft Visual Web developer 2005 express edition?
Look forward to all comments?
Regards
 
Philip

SQL Server 2008 :: Replicate Only Specific Data To Specific Subscriber?

Jun 30, 2015

We have a "main" SQL 2014 server who imports XML files using SSIS in a datacenter. In remote sites (which are warehouses), there is an instance of SQL 2014 Express. A merge replication is setup, as every operations done on each site must be "forwared" to the main database, as some XML files are generated as output for an ERP system.

Now, the merge replication replicate all the data to the server on each sites. But a specific site don't need the data of every other sites, only the data relevant to itself (which is the warehouse code). Is there a way to replicate only the data relevant to each individual sites to the subscribers? Or is there a better way than replication to accomplish this?

Can Logging Be Turned Off On Inserts To A Specific Temp Table From A Specific Sp?

Oct 10, 2007

I want to ship 500,000 aged transactions each night to an archive table and delete them from their source table in one or more logical units of work (LUW). Each row is approx 60 bytes and there is only one non clustered index on the source table presently.

I'm trying to weigh the pros and cons of 3 alternatives. One of them would basically insert the non-aged rows into tempdb, ship the aged records, truncate the table and then insert the tempdb records back into their source all in the same LUW.

For this alternative, I'd at least like to turn off logging when the records get inserted into tempdb as I dont see any value in logging that part of the activity. Is this possible?

How To Select A Specific Value From Dataset To Fill A Specific Cell ?

Mar 27, 2007

Hi there !

Thanks for taking the time to read this thread.

I don't know whether anyone has this problem, but I am definitely not using the right keywords to search for a thread.

My situation is this...

I have a dataset that has values to fill cells to multiple tables in a report.
However, I only want to select specific data from the dataset to fill textboxes and others.
I cannot change the stored procedure, but the sample of the data is shown below:-


Row Stat Val
0 dtRpt1 02/01/2005
1 Value1 1
2 Value2 2000
3 dtMailSent 02/28/2005
4 Value3 0
5 Value4 5
6 Value5 658

I know it looks weird, but the row really represents which "row" or textbox is it to fill with the Val. The Stat Column is just a way to make sure that I am filling the right values.

so my new report would have multiple tables to denote different categories.
In my first table, I tried putting the cells as follows:-
(expressions are highlighted in italics and bold)

TextBox1 =IIF(Fields!Row.Value =0, Fields!Val.Value,"")

Table1
Column1
DetailRow1 =IIF(Fields!Row.Value =1, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =2, Fields!Val.Value,"")


Table2
Column1
DetailRow1 =IIF(Fields!Row.Value =3, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =4, Fields!Val.Value,"")
DetailRow3 =IIF(Fields!Row.Value =5, Fields!Val.Value,"")
DetailRow4 =IIF(Fields!Row.Value =6, Fields!Val.Value,"")


I only expect this report to print out one page holding the previous values.

However, it ended up printing like this

----------------------------------------------------------

Table1
Column1
DetailRow1 1
DetailRow2

Column1
DetailRow1
DetailRow2 2000


Table2
Column1
DetailRow1 02/28/2005
DetailRow2
DetailRow3
DetailRow4

Table2
Column1
DetailRow1
DetailRow2 0
DetailRow3
DetailRow4

Table2
Column1
DetailRow1
DetailRow2
DetailRow3 5
DetailRow4

Table2
Column1
DetailRow1
DetailRow2
DetailRow3
DetailRow4 658

------------------------------------------------------

I tried putting it into the headerrows instead of DetailRows, and it ended up printing the last value.
Is there anyway to do this ? print all the values out in one table ? I tried using textboxes, but I think I got my expression wrong.

Is this the correct expression ?

=IIF((Fields!Row.Value,"Dataset") =1, (Fields!Val.value, "Dataset"), "")

and it give me an error
The value expression for the textbox €˜textbox5€™ contains an error: [BC30455] Argument not specified for parameter 'FalsePart' of 'Public Function IIf(Expression As Boolean, TruePart As Object, FalsePart As Object) As Object'.

Appreciate any advice or suggestion for this scenario !

Thanks!

Not Equal Date Comparison

Nov 13, 2000

I'm having a problem with what should be a simple TSQL statement. I have a
table which has a datetime field updated. After the update if I type

select * from patient_medication where rec_status_date = '11/10/2000'
it returns the rows I want.(All the dates have a time of 00:00:00.000.
But if I type
select * from patient_medication where rec_status_date <> '11/10/2000'
or select * from patient_medication where rec_status_date != '11/10/2000'

The rows that have a value are returned, but none of the null values
are returned. Will nulls not work with this comparison?

Conflict In Equal-to-operation

Jul 21, 2006

Hi there,

I am trying to update one table on server A/database A with new records from a server B/database B.

Both databases use the same collation. The key-fields of both table do use the same collation, but not the server.

Help: I was thinking, when both databases and the fields inside the tables do both use the same collation, then there will not upcome any conflict ?

Do I have to adapt the database collation, too ? This would'nt be nice as I am retreiving data from different servers with different server collations...
Anybody else got the same problem ?

Thx in advance
