I have a three server peer-to-peer replication setup that includes articles for tables and views. As I understand the BOL, scheme changes -- which I take to mean changes, amont other things, changes in the design of a table or view -- should automatically replicate to the other servers in the topology. Here are my quesitons:
When including a view as part of the publication, what is it, exactly, that is getting replicated? If all the tables supporting a given view are being replicated, and the view exists on all three boxes, whatelse, besides the view schema (and changes thereto) is being replicated?
Secondly, if in fact schema changes are replicated, why can't I modify a view that is part of a publication? When I try to make a change to such a view, I get a server timeout message, every single time. When I remove the view from the publication, I can make the modification with no trouble. What does replicating schema changes mean if I can't make changes to the schema?
I read that views can't be published with SQL Server 2005 replication. Is this planned for the future? If not what alternatives are there for this?
Simple collecting the data needed in a new table ain't a solution for us (memory consuming). And joining the data on the PPC ain't a good solution either (memory and time consuming). We only want to pull the data.
Hi Folks Is there an easy way around this ? One Way Transactional Rep Subscriber needs SCHEMABINDING on the majority of their Views (require View Indexes) which read from Replicated Tables. Main table has 4 Million Rows ReInitialize Subscription Errors with Cannot Drop Table because it is being referenced By Object ..... [schemaBound View] GW
And it involved my favourite Design Technique - Simplicity
So to achieve Simple Replication across geographically disparate Servers we could use:-
300 plus SQL2000 Servers enabling 1000 Concurrent Active Clients (10% actual light Activity) WAN = National Private Secured (ping 300ms max) (128kbps leased line Min) One Interface Server constantly Running A Simple Dynamically Built Partitioned View (removing down servers) One Stored Proc (or more) that Synchronizes the DPV Updateable Partitioned View with Interface Mirror Table DeNormalized Holding a Physical Copy of each of the Subscribers/Publishers/Client Sql Servers Data
The Question is:-
Was my Dream a Nightmare OR A Dream Come True ?
I Know it's down to the Network Quality to a great degree but (That's the suck it and see part of the question) but as a form of replication it seems a very simple platform that could possibly tackle our friend The DCP (Data Consistency Problem) with Client Update DateTime Column & frequent activation (30 Secs).
Has anyone had much experience with this type of Scaling out over a WAN ?
All of a sudden none of our merge replications are working. In fact you can't even insert, update or delete and data from the tables in the merge publication. When trying that, we get an error stating:
Msg 550, Level 16, State 1, Procedure MSmerge_ins_E3F43EF8B259476099BBB194A2E1708C, Line 42 The attempted insert or update failed because the target view either specifies WITH CHECK OPTION or spans a view that specifies WITH CHECK OPTION and one or more rows resulting from the operation did not qualify under the CHECK OPTION constraint. The statement has been terminated.
Currently, the only solution I've found is to delete the publication and recreate it. I'm trying to figure out why this happened. It happened on a development server that to my knowledge, hasn't been changed in a week or so outside of changing the server's IP address. Would that cause such an error to occur?
We have merge replication running with anamous subscribers We have generested lots of views tables and stored procedures like sp_ins_C435D35DDEC04FE2517CCD52A9024EC4
There is a view in our replicated SQL-2000 database, that returns all user tables and views with replication state (0 if not included into publication, 1 if included):
Code Snippet
CREATE VIEW [dbo].[ViewREPL_PublishedObjects]
AS
SELECT TOP 100 PERCENT
CASE [xtype]
WHEN 'U' THEN 'Table'
WHEN 'V' THEN 'View'
ELSE NULL END AS [Object Type],
[name] AS [Object Name],
CASE WHEN [replinfo] = 0
THEN 0 ELSE 1
END AS [Replicated]
FROM [sysobjects]
WHERE
[xtype] in ('U', 'V')
AND [status] > 0
ORDER BY
(CASE [xtype]
WHEN 'U' THEN 1
WHEN 'V' THEN 2
ELSE 10
END),
[name]
Now we need to upgrade our database to SQL-2005, but [sysobjects] table have been changed, so neither Replicated state could be determined according on [replinfo] column value, nor User/System object according on [status].
So, I need a view with same functionality, that will work under SQL-2005 and 2008.
Fellow database developers,I would like to draw on your experience with views. I have a databasethat includes many views. Sometimes, views contains other views, andthose views in turn may contain views. In fact, I have some views inmy database that are a product of nested views of up to 6 levels deep!The reason we did this was.1. Object-oriented in nature. Makes it easy to work with them.2. Changing an underlying view (adding new fields, removing etc),automatically the higher up views inherit this new information. Thismake maintenance very easy.3. These nested views are only ever used for the reporting side of ourapplication, not for the day-to-day database use by the application.We use Crystal Reports and Crystal is smart enough (can't believe Ijust said that about Crystal) to only pull back the fields that arebeing accessed by the report. In other words, Crystal will issue aSelect field1, field2, field3 from ReportingView Where .... eventhough "ReportingView" contains a long list of fields.Problems I can see.1. Parent views generally use "Select * From childview". This meansthat we have to execute a "sp_refreshview" command against all viewswhenever child views are altered.2. Parent views return a lot of information that isn't necessarilyused.3. Makes it harder to track down exactly where the information iscoming from. You have to drill right through to the child view to seethe raw table joins etc.Does anyone have any comments on this database design? I would love tohear your opinions and tales from the trenches.Best regards,Rod.
Hi,I have a sql query like this select avg([mycolumn]) from data where date > '1/5/08' and date < '1/10/08' group by [mycolumn]order by [mycolumn] descIf all values within that average are numbers, I'm fine. If it's a 0 (not a null, a 0) it doesn't get averaged in. For instance, values 0,1,2 should produce an average of 1.(0+1+2)/3 = 1. But sql is returning a value as if my 0's were nulls and not factored in: (1+2)/2 = 1.5Does anyone know why this is happening and how to fix it?

Newbie here. I've only been using SQL for about a year now and have some minor questions about sql objects that reference other objects.
We have some views which reference other views in the joins. I will call one the primary view and the one being referenced in the joins as the secondary view.
Recently we made changes to the secondary view.
After which the primary views which referenced it would not work because of this change and had to be 'refreshed' by using drop/create scripts which essentially just dropped it and recreated the exact same view. I do not recall the exact error message that was returned other than it seemed to suggest that it could no longer see the secondary view since it had been changed. Nothing in the primary view was changed in any way, just the secondary.
Some here where I work have suggested off hand that this was a recompile of the primary view because the contents of the secondary changed.
My questions are:
1. Exactly why did this happen and is there a proper name for it when it does?
2. The same problem does not seem to occur when we have stored procedures referencing views in the joins which had just been changed. Why is that?
Thanks for any help on the matter. I greatly appreciate it.
Hi,I'm trying to include a button control inside an iff where I am showing the results of a datalist. My aim is for each user listed, to show whether or not he is already a friend of the logged in user. To do this, I want to create an iff where if the user is already a friend, I will show the text "already a friend". If the user is not yet a friend, there will be a button saying "add as friend" which when clicked will execute an insert query to the database to add that user as a friend. I tried the code below, but it doesn't seem to recognize the button inside the iff. I really need a button to work if the result of the iff condition is DBNull.Value... Can anyone please help? <%#IIf(Container.DataItem("userNameIfFriend") Is DBNull.Value, "<asp:LinkButton id='addbuddy' runat='server' > Add as buddy</asp:LinkButton>", "Already buddy")%> I also tried the code below instead, but it doesn't work either, and I do not know what to include instead of true and false, since the button would only be enabled if the case was true. <asp:LinkButton id='addbuddy' runat='server' Enabled="<%#IIf(DataBinder.Eval(Container.DataItem, “userNameIfFriend�) is DBNull.Value, “True�, “False�)%>">Add as friend</asp:LinkButton> Thanks a lot.
Collin writes "i have tried to do a query between 2 different tables that have different columns. within both these tables there is a column that has a column name different from the column name of the other table but the data within both columns is the same. i wanted a query that compares the data between the 2 tables.
Example is:
Table 1 Columns : firstname , age , id , grade.
Table 2 Columns : name, sex , school.
lets say that the data of column "firstname" of table 1 contains the same data as column "name" of table 2 and i would want to do a query that retrieves records for where data in the column "firstname" in table 1 is found in column "name" of table 2.

I'm using reporting services actions to execute some javascript. My javascript is quite complicated. Thus I don't want to duplicated it on each item. I've created javascript function and wan't to execute it from actions. But I can't find the way how to include my javascript code into my reports. If there's way to include it for all reports generated on reporting services server - it works fine for me.
Hi, I'm trying to write a SQL SELECT statement where the phone numer ("telnr") is divided on three rows. How do I write a newline? I've tried , NEWLINE, and a few others. Thanks in advance! Pettrer, Sweden (VB, Sql Server, VWD Express, Asp.Net 2.0) Code: SelectCommand="SELECT [gID], [enamn], [fnamn], telnr1 + ' ' + telnr2 + ' ' + telnr3 As telnr, [epost] FROM... The corresponding gridview's cell's value is 08-43 244 234 08-432 23 08-424333 and should be 08-43 244 234 08-432 23 08-424333
Here's my situation: I need to move several application db's to a new server. The current server is SQL 7.0 SP2, the new server will be SQL 7.0 SP3.
In order to avoid having the problems of mismatched logins and db user definitions, I'd like to restore the current master over the master that's created at install on the new server.
I was doing some testing of this by trying to restore the 7.0 SP2 master onto a SQL 7.0 DE edition and had some problems. (Obviously, this is not the exact scenario that I need to take place -- I want to restore standard edition to standard edition.)
Is restoring the master db from different service packs under 7.0 going to pose a problem? Is restoring the master db the best way to get around the logins issue when moving db's?
I am trying to write a stored procedure that will automatically link a server and then run a stored proc on the newly linked server. At the end the stored proc will drop the server. I do not want a permanantly linked server due to the fact that this only has to be ran once a month, can you run a remote stored proc any other way then linking the servers?? Cheers to all who reply
I have a table of students, and a table of lecturers, and I wish to use one select statement to return a list of users.
What I really need to do is something like this:
SELECT Students.UserID AS UserID, Lecturers.UserID AS UserID, Students.FullName AS FullName, Lecturers.FullName AS FullName FROM Students, Lecturers
which would (in my dream world!) produce something like:
UserID FullName s0002131 Darren Student s0054242 Richard Student e13412 Michael Lecturer x92342 Linda Lecturer
Does anyone know how I should do this? Should I be doing it in an stored proceedure and returning the record set from that? Currently I'm only using ASP and one line SQL statements, and would like to continue doing so.
Hello, I understand that we should use SSMS -> Server Properties -> Memory to put a cap on the SQL server memory usage, therefore it gives some space memory for OS, this is based on the fact if the max memory is not specified, SQL will use whatever available memory and eventually crash the system.
My question is that when a server has SSIS and SSAS services installed along with the SQL service. Would the max memory setting covers the SSIS and SSAS memory usage, or the SSIS and SSAS has to shared the memory with OS?
Hi,I have 2 tables, Mail_subject and Mail_Usage.Mail_Subject contains the subject, body and some other bits of info.CREATE TABLE [Waterford_MailSubject] ([ID] [int] NOT NULL ,[MailSubject] [nvarchar] (50) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[MailCategory] [nvarchar] (50) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[MailBody] [ntext] COLLATE SQL_Latin1_General_CP1_CS_AS NULL ,[MailCreateDate] [smalldatetime] NOT NULL) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]GOMail_Usage records the amount of times a certain mail was sent.CREATE TABLE [Waterford_MailUsage] ([ID] [int] NOT NULL ,[RepScreenName] [nvarchar] (50) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[MemberScreenName] [nvarchar] (50) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[MailSubject] [nvarchar] (50) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[TimeDate] [smalldatetime] NULL ,) ON [PRIMARY]GOThey are joined by Subject (not my idea, its a DB ive inherited).What i need is to get the Mail Subject and the number of times thatMail was sent. Ive Joined them using an INNER JOIN which gave me acount of the number of times each one occoured except for Mails thathave not been used. I need to get zero as the count of Mails notsent. Ive tried a LEFT OUTER JOIN but it didnt work either.Can someone point out what i need to do ?
I've seen plenty of posts regarding the estimation of table size,usually in the processing of planning for server storage needs.Well, I've got a different problem. I need to know how much data eachof our Customers are using in a Database. (1 SQL DB stores multiplecustomers).Basically, I want to be able to say: Customer A: 45.5 MB, Customer B:655 MB.So, how can I ask SQL Server how much data each Row in each table istaking up? I want to be able to calculate nightly the total size, so Iwould take each row in each table that belong to the customer, and addall the sizes together. I want to take into account blobs that arestoring images and PDF files also.Thanks in advance,Jesse Wolgamott
Hi, I am hoping someone may have tried this before.......
Our application takes user details from Active directory, and stores the Guid in the database against an autonumber field for an easy to use userid. Any time the application wants to know anything about the user, it gets the information from Active Directory based upon the stored Guid.
I am writing a query to be used in generating reports, so I don't want to use .NET, Only SQL. I would like to be able to extract the username from Active Directory using SQL, so that the user's name, and not just their ID can be used in the report.
So far I have been able to extract all of my users names and their Guids from Active Directory using SQL, and I can extract the user Guid from our database. The problem I am having is comparing the 2! Visually they look the same, however the datatypes are different. If I convert the ActiveDirectory Guid to varchar I get gobbledegook, and if I convert the stored database Guid to varbinary then it's value is changed.
The query as it stands is below:
SELECT convert(varchar(50), [Name]) as FullName,objectGUID,ADSPath FROM openquery(ADSI, 'SELECT name, objectGuid, ADSPath FROM ''<LDAP Path>'' WHERE objectClass = ''User''') WHERE objectGuid in(Select ADObjectGUID FROM users WHERE UserId='1')
I am working with SQL Server 2000 - as many of our clients are still using this system, so solutions based on SQL Server 2005 would not be practical. (I beleive there are ways of running .NET code from SQL 2005 which would solve this problem)
Im try to use SQL server 2000 and use Enterprise to cript a table But my result is only table structure in the script (myfile.sql) (something like "create table Tb1, column..") and not have any data in my table included. how good it is if it can write some insert statement (depend on number of records existed). Could I have any way to do it with MS SQLServer 2000? Thank you much. DongMT
I am trying to add an Imports statement to the beggining of the custome code section of my report but I recieve this error. There is an error on line 0 of custom code: [BC30465] 'Imports' statements must precede any declarations.
We are thinking of using a Sql Server Express database (.mdb.mdf) as a data resource in a Windows Forms application that we will be distributing to clients. When the application is built, the mdb file is copied to the bin directory.
In order for clients to access this database, will they need to have an instance of the SQLEXPRESS server installed on their computer? Or since the .mdb.mdf file is being accessed from a .Net 2.0 application, there is no need to install a separate db component?
If I do have to separately install the db component on the client end, is this the way to go about it? This? Or is there a different/better way?
