Merge Two Databases In One Database.

Oct 26, 2007

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.

Sync/Merge Local Sql Compact Databases To Single Global Database

Jun 23, 2007

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

Merge 2 Databases?

Jan 19, 2006

My problem is this:

I have a database file on a hard disk.  I have to read that data and merge it into a database on a sql server.  How can you merge ?  The databases are set up the exact same way.  The only difference in them is the data.

Also, in the database file I have image names, I have to compare them to what is on the database on the sql server.

Thanks

Merge Databases

Apr 26, 2007

I have 2 database, one has data and one is being created on my handheld. Is there a way to merge the database together so I get the data in the tables I need in the database being create or can I add tables to the existing database so I can use that for my testing?



here is the issue;

database 1 has tables with data - but does not have all the tables I need. - pre-existing

database 2 is being created when I start my app, and creates the tables I need but no data and not all the tables.



Is there a way to merge these to, so I don't have to create a huge insert statements for each tables I need data for?

or can I do a select from database 1 and insert the records into database 2?



example: insert into tbl1 (name) select database 2.table(col1) from tbl1, is this possible?

Merge Replication Between Two Existing Databases?

Apr 18, 2006

Hi gang,

We have a couple of databases on separate servers that have exactly the same schema, and we would like to set up merge replication between them.

Is that possible? The few times we've experimented on test databases, the subscriber database has been trashed and rebuilt using data from the publisher, rather than preserving data from both databases.

I'm really new to replication in general, so any kind of advice would be helpful.

Cheers,
Matt

Merge Replication Between Same Schema Databases But Different Data

Jan 25, 2007

Hi all.

I 'm trying to set up merge replication between two servers that have the same schema databases. The two database have the majority of there data the same but as well as data inserted at a later time independently on the two servers. (The two servers were connected in a merge replication scheme that failed at some later  time and replication was paused, but users continout to insert data indepentedly at the two servers.)

I need to get them up and running.

I cleaned replication at both servers, I recreated the publication at the puplisher distributor and all is fine.

When I create a push subscription to the subscriper I get the error invalid column name 'rowguidcol' .

I so far managed to have merge replication running on two identical databases (schema and data).

Just some thoughts. After some reading I found that it might be related to identities and identity range or indexes.  I set the identity seed  and increment at 2, 2 at publisher and at 1,2 at subscriper. (On the same tables at  puplisher and subscriber.) Is that ok? is that the way to do it?

Digging a bit more  Using the SQL Profiler I can locate the error to happen when sp_MSaddmergetriggers executes.

Thanks allot for any help

Moving A Merge-replicated Database For SQL CE

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.

Cannot Open Database During Merge Replication

Mar 12, 2007

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

Enumerate Subscriptions In A Merge Replicated CE Database?

Jun 27, 2007



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

Many Databases Vs. 1 Database

Jul 23, 2005

Hi,I am trying to determine what the overhead is per database in SQLServer 2000 Standard. I have the option to put several customers in onedatabase, or give each customer their own database. I would like to puteach customer in their own database to simplify maintenance andstrengthen security.I have found the following document which shows the memory used byvarious objects in SQL Server:http://msdn.microsoft.com/library/d..._ar_ts_8dbn.aspBased on this info I get the following *additional* memory requirementsper database:Open Database (1 file, 1 filegroup): 6kOpen Objects (250 objects, 30 indexes): 692kTotal: 698kIs this an accurate calculation of the overhead? Is there somethingelse that would affect the overhead that I am overlooking? Are thereany other downsides to having many databases versus a few databases?Thanks,Mike

Merge Repliction - Run Stored Procedure When Merge Agent Starts

Jul 23, 2005

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.

Need An Optimal Way To Merge External Dataset To Database Values

Jan 3, 2008

C# .Net Application as front end
Sql Server2000 as back end

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..

One Database Vs. Multiple Databases

Jun 20, 2006

I need to design a system which represents multiple "projects" in SQLServer. Each project has the same data model, but is independent of allothers. My inclination is to use one database to store all projects.Looking at the numbers involved, however, I wonder if I would getbetter performance by storing each project in its own database.Suppose I have 50 projects, each with two users and 10,000 rows; itseems to me I'd rather have 50 x 2 users working in a table with 10,000rows than 1 x 100 users working in a table with 500,000 rows.On the other hand, the single database approach seems more elegant froma design perspective. I wouldn't be creating multiple copies of anidentical data model, and I wouldn't be creating new databases as abusiness procedure, every time a new project is required.Here are my questions:1. For the scenario described above, am I correct to assume I will getbetter performance by using multiple databases, or does SQL Server havesome clever way of achieving the same performance in a single database?2. Is the multiple database approach common? If anyone has tried it,please tell me about how it works in practice.-TC

Server.Databases.Count=0 Although There Is A Database

Oct 14, 2007












Hi, everyone!

I have the following problem:

I want to process a cube daily via remote connection (http://cubeserver/olap/msmdpump.dll), using a Script Task in a SSIS package.

1. Running the package with the Execute Package Utility works fine, the cube will be processed.
2. With this SSIS package I created a job that runs daily and everything was fine until 3 weeks ago. Since than I have the following problem:

SSAS Server is connected:

oServer.connected=True

,but further I find no database:

oServer.Databases.Count=0,

although there is at least one database.

Of course, running the package with the Execute Package Utility:
oServer.Databases.Count=1
and I can go on with the processing.


I used in both cases the same Package and the same configuration file, the connection string is the same.
Both computers run SQL Server 2005 SP2.

I truly appreciate your help,
Cristina.

Change A Merge Subscriber To Become A Merge Publisher

Aug 16, 2004

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,
Jez W
