I need to add 1 new field
What is the best way of doing this ?
I have previously removed the publications, subscribers, added the
field and pushed the whole database out
Please advise

Hello I currently have a merge replication set up with 4 subscribers. A primary field for one of my tables is set to a integer indetity.
What Ive noticed is that depending on which database I enter data into, the indentity field (primary key) is set within a certain range I.e
On Server 1 - Values start from 1 then 2,3,4 etc etc
Server 2 - 24001, 24002, 24003 etc etc
Server 3 - 46001, 46002, 46003 etc etc
Server 4 - 68001, 68002, 68003
My question is what happens when these ranges eventually conflict? Do they automatically gain a different range such as 142 001, 142 002 etc etc?
Ive tried looking in SQL Help, and a quick search here, Im just after some confirmation before I implement this to my app.
cheers
I'm doing a data conversion with one of my fields (SUMDWK) from one of the tables that will be used in a merge join. With the new, converted field, I do a look up. From this look up, I want to take a new field FiscalWeekOfYear, and replace the original field, SUMDWK. This is necessary because SUMDWK is one of the sorted fields. In the look up, it is not possible to change the Output Alias. Does anybody know a way around this? Thanks.
I am new to sql and my boss want me to write the program for database and he wants to pull the info from existing table from sql server which is used by Microsoft GP Dynamics and write me code or some kind of front end so when he wants he can pull same data from GP dynamics table and generate some report with other custom table.
How i can do this task? What I have to do in sql so I can use same table to view info in real time so that means if i enter new data in the table it will show up same time in the front end as well.
can anyone explain me in detail abt web.cofig and machine.config with an easy and suitable example , also i wana know that as u know that asp.net 2.0 provides a builtin ASPNETDB but it contain limited and general entities for any real time application i have other entites for that i have to make another Database so i hav 2 databases for any application but i want to use only 1 DB ,my question is i want to merge aspnetdb.mdb with my new database do u know how can i merge it ?????? but the functionality of ASPNETDB.mdb remain same
Hi,
I want to share knowledge that we have the abality to merge the two databases in one database. As if your site is already working with data base with out login page. And you are using asp.net built in funtion to create login page there will be a new database will automatically generated with the name of "ASPNETDB.MDF". you will check it in machine.config. If you want to get its data in old one database you only open sdk dos promt and write aspnet_regsql.exe and press enter. A wizard will open for you. in first two wizard you click next without changing it. and in the 3rd page you will enter the database name in which you want to write this ASPNETDB.MDF data. and in the final page you click finished button and close the sdk dos promt.
You should go on web. config file and modify the code for example.<connectionStrings>
<add name="wordexpress" connectionString="server= localhostsqlExpress;Database=wordexpress;Integrated Security=True"providerName="System.Data.sqlClient" />
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="server= localhostsqlExpress;Database=wordexpress;Integrated Security=True"providerName="System.Data.sqlClient" />
</connectionStrings>
And then check your old database you will see that there is new 11 table added.
My question is that I cannot get these table in my old database. I have working with the same procedure. Can any one tell me if there is any mistake from my side.

hi,i have a sqlserver CE and a sqlserver database.The tables are exactly the same on both databases.the sqlserver CE database Content will be synchronized with thesqlserver database with insert orders..is there a way to merge the two databases?this would be great cause different content will be inserted in bothdatabases. After a synchronisation both databases should have the samecontent..i hope you understood my problem. my english is not very well..christian

I've had a look at the SQLServer replication docs and got confused....
Can I do this with replication ?
So if anyone can point me at appropriate documentation, or suggest a good method for this it would be appreciated
Thanks
Is there a way to move a SQL replicated database from one server to another without dropping the publication?
I have SQLCE setup with SQL server 2000; I want to redo the server but needs to move my replication to a temp server and then back.
The problem is that I do not want to drop my subscription and recreate it…it needs to stay the same.
Hi All,
I am replicating an SQL2005 express machine to SQL2005 standard edition server using merge replication.
I have a simple VB application using ADO polling msMerge_history at the subscriber every second so that i can show the end user the progress of the replication.
When the subscription first subscribes and after the initial snapshot is applied replication downloads all changes from the server that have been changed since the snapshot was created.
Towards the end of this download faze the VB polling application fails with "Cannot open database "DBName" requested by the login. The login failed."
This connection fails 4 or 5 times and then normal polling resumes. The scary thing is that sometimes when the polling connection fails the merge replication does not complete and if i check msMerge_Sessions the "runstatus" is stuck at 3 (InProgress).
1) Is the reason the ADO polling connection fails because of some sort of lock between replication and reading the system tables?
2) Is replication getting stuck because of locks?
3) What can i do to get around this?
cheers,
Tim

Hi,
On the development environment i've got replication running with no trouble but when deploying in the production environment i get the error below
Has anyone seen this before and solved it?
Another question: How to enable verbose history when using the MS SQL Server Management Studio to create a subscription.

How can I list all of the Subscriptions in a CE Database that was created with the .Net System.Data.SqlServerCe.SqlCeReplication.AddSubscription method?
After I create the CE database in an sdf file, I can connect to it with SQL Servr Mgmt Studio, then see the list of Subscriptions in the Object TreeView, under "Replication"
But I can't find that Subscription list in any properties or methods of System.Data.SqlServerCe.SqlCeReplication or System.Data.SqlServerCe.SqlCeConnection
Should I be looking in RMO features like Microsoft.SqlServer.Replication??
We want to confirm that a local CE database was last synced from the expected SQL Server database by checking the Publisher property of each subscription in the CE database.
Thanks
I have database on SQL Server 2000 set up with a merge publication.This publication is configured with a number of dynamic filters toreduce the amount of data sent to each client. Each client has ananonymous pull subscription. The merge process can be triggered by thewindows sync manager and my application.To improve performance I have created some helper tables to hold themapping between user login and primary keys of selected entities.For the replicated data to be correct the contents of the helper tablesneeds to be up to date.I need to fire off a stored procedure on the publisher beforereplication starts to verify that this data is up to date. I can notsee any documented way of doing this however I have been experimentingwith some unorthodox systems.Firstly has anyone any ideas?I have been considering adding a trigger to some of the tables used bythe Microsoft replication code - yes I know this is very nasty.My problems arise because executing this stored procedure will causesome data to be updated. In updating data we could create a newgeneration in the database. I must therefore run my stored procedurebefore any the Microsoft code makes any generation checks / updates.Anyone done anything similar, Anyone have any better ideas?Any comments would be gratefully received.
View 1 Replies View RelatedI need to move the log file of a disk and onto another disk. The log belongs to a merge subscription database.
I was going to stop/disable the merge jobs on the distributor, detach the database, move the log file to another drive, reattach, and enable the merge jobs on the distributor.
Does that sound ok, or should I employ some other method.

I need to merge an external dataset from .Net app(in XML format) with the information in database with one column in database table as the merging criteria. A situation similar to Left Outer Join, wherein i need all records from external dataset and if matched in database the corresponding values from there too, the only difference here is that the join is not between two Tables its between a table and external dataset.
There is no need to store the external dataset in the database in persistent form, its just a query - merge - response operation.
So, can anyone suggest the best possible solution for this? A table variable / temporary table / some other schema, what and how?
Thanks in advance..
Hi,
I am developing a application where the database needs to be deployed from the central database server which is sql server 2005, and we have only few fields and few new tables which need to be deployed into pocket pc using sql mobile from sql server 2005.

Could anyone help on the above problem?
Hi all,
When I get this message "The merge process is cleaning up meta data in database 'xDatabase'." at distributor MS SQL 2005 replicator monitor on one of his suscription, this proccess generate so proccess charge to the suscriber that users note difference in performance. I wonder if exist a way to change some kind of parameter for this proccess run on specific schedule ?
Any help would be appreciated.
other info I had suscribers that only replicate in one way, maybe this metadata is causing this overcharge.
Hi, I have compact sql databases which will be local on multiple users
devices. Due to space constraints, for one of the tables i have had to use
auto incrementing integer which works fine for the local database but i
would like to merge all of the users databases into a global database. The
table format can be seen below:
Code SnippetCREATE TABLE Players
(
ID UNIQUEIDENTIFIER NOT NULL PRIMARY KEY,
FirstName NVARCHAR(32),
LastName NVARCHAR(32)
);
CREATE TABLE Sessions
(
ID INTEGER NOT NULL IDENTITY,
PlayerID UNIQUEIDENTIFIER ,
SessionDateTime DATETIME,
CONSTRAINT pkSessions PRIMARY KEY (ID),
CONSTRAINT fkPlayerID FOREIGN KEY (PlayerID) REFERENCES Players(ID)
);
CREATE TABLE SessionDetail
(
SessionID INTEGER,
Time real,
Power real,
CONSTRAINT pkSessionDetail PRIMARY KEY (SessionID,StrokeTime),
CONSTRAINT fkSessionID FOREIGN KEY (SessionID) REFERENCES Sessions(ID)
);
The Players table will merge fine as GUIDs are used. However, how will the
sync capabilities of compact SQL handle the sessions table? When it pushes
the local data to the remote database will it change the Sessions.ID column
to a unique field (as no doubt lots of people will have 1, 2, 3 in their
local databases and the global database must have a unique ID), and then
transfer this changed ID back to the local database? Furthermore, if it
changes the Sessions.ID column during the merge it will also need to update
the SessionDetail.SessionID foreign key to maintain referential integrity,
is this also handled?
So my question is, how much of this sync and data merge is automated and are
there any good examples or pointers for my scenario? I cannot reasonably use
a GUID for Session.ID as there will be lots of SessionDetail entries and the
size would be far too much.
Many thanks,
Chris
Hi,
I'm using merge replication to maintain a backup copy of my main (publisher)MSDE database. A push subscription periodically (1 per minute) updates the backup DB.
It's intended that if the main db goes down then the backup (subscription) db can be configured as a publisher. This must all be performed via scripting.
The initial configuration of the main publisher and subscription is controlled via scripting, which works fine.
The problems occur when I try to configure the subsciber to become a publisher. A script is executed on the subscriber but fails at the point when it's configuring the publisher detail. The error is something like "unable to configure a publication for a database setup as an anonymous subscription".
I'm guessing that there are subscritpion artifacts added to the database which need to be removed before it can be configured as a new publisher.
Please help,

alo people..
so..this is my question regarding to gridview.. is possible to put the field inside the gridview if it is not exist in the database..

hi
I have used the following code (mostly created by MSDN) to retrive a binary field from SQL database. it works but I have extra space between characters. for example if I save a text file with "Hello world" text, after retriving I have it like "H e l l o w o r l d". what is the problem??????
I am really looking forward your answers
private void retrive()
{
public void a()
{
SqlConnection connection = new SqlConnection("Some Connection string");
SqlCommand command = new SqlCommand("Select * from temp", connection);
// Writes the BLOB to a file
FileStream stream;
// Streams the BLOB to the FileStream object.
BinaryWriter writer;
// Size of the BLOB buffer.
int bufferSize = 50;
// The BLOB byte[] buffer to be filled by GetBytes.
byte[] outByte = new byte[bufferSize];
// The bytes returned from GetBytes.
long retval;
// The starting position in the BLOB output.
long startIndex = 0;
// Open the connection and read data into the DataReader.
connection.Open();
SqlDataReader reader = command.ExecuteReader(CommandBehavior.SequentialAccess);
while (reader.Read())
{
// Create a file to hold the output.
stream = new FileStream(
"C:\file.txt", FileMode.OpenOrCreate, FileAccess.Write);
writer = new BinaryWriter(stream);
// Reset the starting byte for the new BLOB.
startIndex = 0;
// Read bytes into outByte[] and retain the number of bytes returned.
retval = reader.GetBytes(0, startIndex, outByte, 0, bufferSize);
// Continue while there are bytes beyond the size of the buffer.
while (retval == bufferSize)
{
writer.Write(outByte);
writer.Flush();
// Reposition start index to end of last buffer and fill buffer.
startIndex += bufferSize;
retval = reader.GetBytes(0, startIndex, outByte, 0, bufferSize);
}
// Write the remaining buffer.
if (retval != 0)
writer.Write(outByte, 0, (int)retval - 1);
writer.Flush();
// Close the output file.
writer.Close();
stream.Close();
}
// Close the reader and the connection.
reader.Close();
connection.Close();
}

Hi,
I'm using the SQL Datasource control. I want to use a value of a row in a session control parameter.
I have something like this now:
<asp:SessionParameter Name="ArticleType" SessionField="Article_type_" & number_in_gridview />
number_in_gridview
must be filled with a value in the gridview of the current row.
Does anybody how to do this ?

Hello,
I have a database design question. I want to store a status in a table. In the ASP.NET interface for the user this status will be adapted to the language of the user.
This is how it would look like:
StatusID 1 = "yes" for English, "oui" for French, "ja" for DutchStatusID 2 = "no" for English, "non" for French, "neen" for DutchStatusID 3 = "error" for English, "erreur" for French, "fout" for Dutch
I don't want to do the translation in ASP.NET and it should be done in one query.
How would it look like in the database design.
Hi,
I am building a website in ASP.net C# for a university project, and would like to search a table (Member) for a field (UserName) using a session variable Session["sUserName"]. If that field is null, then I would like to insert that session variable into the field to start to create a new user. However, I am getting errors saying that I am using invalid expression terms. My code is;
//Create the Command, passing in the SQL statement and the ConnectionString queryString = "SELECT UserName FROM Member WHERE (UserName = @myUsername); ";
SqlCommand cmd = new SqlCommand(queryString, sqlConn);cmd.Parameters.Add(new SqlParameter("@myUsername", Convert.ToString(Session["sUserName"])));
//If UserName is null, display confirmation, else display errorif (UserName == null) ;
{UserNameCheckLabel.Text = "Username okay";
String queryString = "INSERT INTO Member (UserName) VALUES(@myUsername); ";SqlCommand cmd = new SqlCommand(queryString, sqlConn); cmd.Parameters.Add(new SqlParameter("@myUsername", Convert.ToString(Session["sUserName"])));
}else;
{UserNameCheckLabel.Text = "That username is in use";
}
I have a feeling I should be checking the database for the UserName, but I'm not sure whether to put this in the SELECT statement part or as a method... I would be most grateful for any advice!
Many thanks,
Chima
Is it possible, using VB code, to retain a user on a particular page
until the status of a certain field in a database is changed?
The scenario I am working on is that a person makes a reservation and
has to wait until that reservation has been accepted or rejected by the
administration.
Dim dsResv As DataSet
dsResv = objResv.DALgetResvStatus(resvId)
While (dsResv.Tables(0).Rows(0).Item("resvStatus") = "pending")
dsResv = objResv.DALgetResvStatus(resvId)
If
dsResv.Tables(0).Rows(0).Item("resvStatus") = "denied" Then
failure.Visible = True
LinkButton1.Visible = True
ElseIf dsResv.Tables(0).Rows(0).Item("resvStatus") = "reserved" Then
success.Visible = True
LinkButton1.Visible = True
End If
End While
This is how I tried to do it, but it doesnt seem to work.
Any suggestions?

Hi,
Does anyone know how to encrpyt a field in a table created in SQL Server Database.
