Database Schema Comparison
Jul 13, 2007
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?
Thank you,
Jim

I've been testing a variety of database schema migration tools. Ourcompany purchased Embarcadero Change Manager a while ago but we'vebeen less than satisfied with the results.We are looking for a tool that can compare a source/developer databasewith a target/client database and then make the necessary changes.The tool will need to update stored procedures, tables, indexes,constraints, etc. The tool will also need to make the changes in thecorrect order based on dependencies and relationships.Anyone have any recommendations?

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!

I had an application go down yesterday...it was giving a Type Mismatch error and the support team couldn't figure it out.
My suspicion is that a field in the database got populated with a character the vb app didn't like when it renders the information.
I'd like to prove that theory...but the database is large (4gb) and I'm not sure how to do a database comparison to see where the records differ.
Anybody have a script to get me started OR some experience to share?
Thanks,

Hi, I'm looking for a tool to compare 2 sql server database and makes a script of the differences (like an added table or record). We want to use it to generate a script which we can send to our customers to update their database if a change has been made. Example: We send our customers database A. After half a a year they request some changes to be made to the application that affects the database, say a table has to be added. We want the tool to automatically detect the difference between database A when it was first released and after the changes has been made and generate a script. Anyone suggestions? T.I.A., ratjetoes.

The error message:
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!?!?)

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
drop role [ReadOnlyRole]
go

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)?

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?
Forgive my sarcasm and Thanks in advance.

Hi,
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?
Thank you very much!

MS SQL 6.5
NT
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....
Thanks in advance.

Case 1:
A company is involved into e-commerce..hosting multiple websites for different products.
CAse 2:
The above scenario could also be implemented with a single site having multiple products for sale.
For Case 2 one would go for a single database for all the products.
While for CAse 1 ,a separate Database is developed for each Site.
What I fill is CAse2 is a more appropriate choice even if we have multiple sites for different products.
This would help us in rapid development of any ecommerce site...
ANd better ERP management for the Company.
I would appreciate some expert guidelines for the above scenario
Thanx in Advance
Warm Regards

I can't believe I am asking this but I have been "requested" to.
Scenario:
Database based app installed on client site
Goal:
Protection of database schema.
Solution:
Obfuscate? - Any tools available?
Host db in secure location - Not going to happen!
Any thoughts?
