We currently have a product in which each client has their own Database. We adjust the connection when a user for that client logs into the system. This system has continued to grow and a good pace, but we have come to a point where failover is taking too long.
Refactoring the Database to handle multiple sites in a single database is not an option because of the time it would take to make the change. So, we are looking for another way in which this could be handle. One idea is to take multiple clients and place them in a single database using a schema to seperate them. (ex. Client A = server1.db1.schema1, Client B = server1.db1.schema2, etc).
Is there another option that would be better, or what kind of performance can we expect if we follow this path? Or, is there a way to decrease the failover time (it appears the problem is the startup of the database on the failover server)?
Locally I develop in SQL server 2005 enterprise. Recently I recreated my db on the server of my hosting company (in sql server 2005 express).I basically recreated the tables and copied the data in it.I now receive the following error when I hit the DB:The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version.I heard something about running aspnet_regsql.exe, but I dont have that access to the DB. Also I dont know if this command does anything more than creating the membership tables and filling it with some default data...Any other solutions/thought on what this can be?Thanks!

An error has occurred during report processing. (rsProcessingAborted) Query execution failed for data set 'TestID'. (rsErrorExecutingCommand) For more information about this error navigate to the report server on the local server machine, or enable remote errors
The log file reads:
---> Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Query execution failed for data set 'TestID'. ---> System.Data.SqlClient.SqlException: SELECT permission denied on object 'TableID', database 'Database', schema 'dbo'.
***Background***
General Users got an error message when trying to access any reports we have created. All admin have no problems with the reports. Users (Domain Users) are given rights (Browser) to the reports and the Data Sources (Browser) and yet cannot view the reports.
An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'DS2'. (rsErrorOpeningConnection) For more information about this error navigate to the report server on the local server machine, or enable remote errors
I'll add this from the report logs...
w3wp!processing!1!3/20/2007-11:43:25:: e ERROR: Data source €˜DS2€™: An error has occurred. Details: Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Cannot create a connection to data source €˜DS2€™. ---> System.Data.SqlClient.SqlException: Cannot open database €œDatabase€? requested by the login. The login failed. Login failed for user €˜DOMAINUsername€™.
The user has rights via a local group to the report and data source (Browser rights) and the local group has been added as a SQL login.
I gave rights to the databases themselves instead of just to SQL and the error changed (Ah-ha...progress, but why!?!?)
I need to export a database, x, of a server, X, to another database, y, of a server, Y and I need export the database schema only, not include the data. Does anyone know how to do that? Many thanks for replying.
Trying to get my hands around all the new security features of SQL Server 2005. In Management Studio did something I don't know how to undo. I added a database role ReadOnlyRole and clicked the box next to db_datareader in the owned schemas box. Then I tried to remove the ReadOnlyRole and could not. How do I undo what I did? Is it possible?
The below is the TSQL that generates the my issue.
Use [master] go create database [test] go
USE [test] GO
CREATE ROLE [ReadOnlyRole] GO
USE [test] GO
ALTER AUTHORIZATION ON SCHEMA::[db_datareader] TO [ReadOnlyRole] GO
here is my problem. I have to rebuild database after crash. there is no backup. So I did a bcp to get data from. But I do not have the original database so my question is how to get the full schema off the data base, tables,colomns,stored procedures etc...
Hi. I would like to retrieve the table names of a database, the column names nad its contraints of each table in a database.. How can this be achieved???
We have a RS 2000 server with a over a hundred reports, and about half as many weekly and monthly subscriptions. In reply to my request to upgrade to RS2005, the boss asked me today for a compete list of the reports, who subscribes to them, and their delivery frequency.
He was not interested in paying for a VB or C# development effort with the SOAP API that it would require to obtain a simple list from a SQL server database, since he already has SQL programmers on staff.
So how can I get this list? Anyone know of any demo code out there?
Is there a way for VS2005 to export the database schema of a .mdf into a .sql file? Preferably from a Web PRoject, not a Database Project, but right now I am anything but picky, so whatever works. Thanks.
SQL Database Schema Sync We have development and production databases, when we change database schema in development database how can I synchronize it to production without creating data problems in production, is this possible in SQL2005? Or any external tool I can use?
Hi all, I am doing a replication of a SQL Server 2005 database from one server to another server, everything worked fine. Now, when I added some fields to this database, the replication stopped. can I do replication of a schema of a SQL database? how? Should the replication work even if I add some fields.
Can anyone help me to figure out how to generate the SQL Script that can produce the same database schema with the existing database?
I have tried the "Generate SQL Script" tool. However, it only creates the object such as tables, stored procedures, triggers and etc. I still have to create the database first in order to run that script. I have an existing database that has a 2.7 GB size (let's called this ABC Database). In a different server, I would like to create the same database with the ABC DB without having to restore the ABC DB. Bottom line, I would like to see the script creates the database along with all stored procedures, triggers and the size of the database will be 2.7 GB. Is it possible?
I have been asked to export the database schema (containing table names, field names, data types, field lengths, field defaults, nulls, etc) to an MS Excel spread sheet. "sp_help filename" provides some data but the format is difficult to manage.
All help with this matter would be greatly appreciated....
Hello all,I am doing some research on database conversions. Currently, I aminterested in any information that would help me convert a database fromone schema to another. This could be changes as minimal as adding afield to a table, or as large as deleting tables and changingrelationships. Unfortunately, my experience with SQL Server is minimal.I know how to do a lot, but I do not know a lot of intricacies thatmost experts know. I know how to add tables, delete them, alterrelationships, add fields, work with stored procedures, take care ofsecurity, etc. I also know how to backup, restore, etc.The type of information I am looking for could be:1) Open source software that performs conversions2) Tutorials/books/<any reference> that would assist me in learningwhat I must to complete this task.3) Third party software that could be used on a large scale andwouldn't resort in unnecessary licensing cost if I was to deploy on thislarge scale.I greatly appreciate any information that could be provided me.To give you guys an idea of my experience level:I've been programming C# and .NET for a year now. I've also hadextensive experience in object-oriented design. I've worked with visualbasic, cobol (did I mention this? LOL), asp.net, php, javascript, andseveral other programming languages on an extensive basis. Whileprogramming is my speciality, I've strayed away from database work untilnow. I would greatly appreciate any assistance in researching this matter.Thanks ahead guys,Shock
Hello all. I am using Sql Compact Edition for a small standalone application, I create and build the initial database schema on initial startup. What I am looking for is a way to upgrade the software and on initial startup of the new version, I would like it to compare the existing database with a new schema and then update the database based on the difference. This way I can have a version that will update the database without me having to know what version it is to begin with. Is there a way to do this or am I asking too much?
What are some basic commands to query information about a CE database schema. I'd like to see my foreign keys etc. Where can I find this information in BOL?

I have written some software using .NET 2.0, a WinForms app, which uses SQL Server Express as a database. Although I've done my best to set up the database to take into account all of the features, etc., after releasing the first version, I need to make some changes to the database schema, but want to do so without wiping out the entire database for existing users. How do I go about upgrading the database schema for users who are already using the software? I'm thinking I should start by writing a helper app to do so whose sole purpose is to upgrade the schema. The app would be run at install-time, but I don't have any idea how to actually upgrade the schema. I am using C++/CLR .NET, but examples in other .NET languages are more than welcome. Any help is greatly appreciated. Thanks!
We currently use SSIS to build DTS packages in which we store changesto our database schema, as well as scripts that need to be run uponeach release. This works well for small sets of changes that neverneed to be updated or for architectures with only one database.We store each of the changes included in the package in separatefiles, which are tracked using version control. It is growing timeconsuming to maintain parity between those files and what is in theSSIS.Furthermore, we have been unable to discover an easy way to load afile's contents into a package SQL Task without opening the file andcopy-pasting the contents into a new SQL task.ANY information at all would be extremely appreciated!
Simple question, I hope. I need to add a column to a table of a database that is mirrored. How do I have to do that? Do I need to stop mirroring? Is it sufficient to simply pause mirroring? If I make the change on the principal db, what do I need to do the make the same change on the mirror?
