I've searched quite a bit, and have found several leads on schema, stored procedure, and database contents comparison scripts and tools.
I'm now looking for recommendations on which ones are best, easiest:
ObjCompare.exe
sb_ABCompareDb.sql
sp_db_comp.sql
There's a mythical script from Andrew Z <mumble> that Mike Hotek talks about...
There's a DBCompare on the Back Office Resource Kit 2 CD, which of course is not in the umpteen MSDN CDs :-(
There's some *other* command line dbcompare, or maybe db_compare.
There's a DBA Compare.
I need to be able to compare divergent schemas from two developers to integrate their changes, so need schema and stored procedures compared only, and would also like to have something to compare staging servers and production servers.
Leads on other choices also welcome. I'd be happy to summarize and post, if warranted.
Hey all,I am currently researching ways to compare databases via an XSD schema.I wrote a small app that creates a dataset from a database and exportsthat dataset to XSD. This gives me an XSD file with tables andrelationships representing the entire database.At this point, I am trying to find ways to compare these schemas. Doesanybody know of a way to do this easily and to record differences ifthere are any?Also, any information on comparing databases using any method would begreatly appreciated.Thanks,--Shock
In the process of purging data to history tables, we wanted to make sure that no schema changes have been done to the main or the history table. So to ensure identical schemas, we use this function:
ALTER FUNCTION dbo.fnCompareTableSchema ( @t1Name NVARCHAR(257) ,@t2Name NVARCHAR(257) ) RETURNS BIT AS /* Compares the schema of 2 tables If the schema is different RETURNS 0 If the schema is identical between the two table, RETURNS 1 NOTE: system tables or non-existant tables that are NOT in INFORMATION_SCHEMA views will compare equal (RETURNS 1) ================================================================================================================== SAMPLE USAGE: DECLARE @schemaOK BIT SELECT @schemaOK = dbo.fnCompareTableSchema('dbo.table1','dbo.table2')
IF @schemaOK = 1 PRINT 'TABLE SCHEMA IDENTICAL' ELSE PRINT 'TABLE SCHEMA DIFFERENT' ================================================================================================================== */ BEGIN IF @t1Name = @t2Name RETURN 1
-- check if schema is different IF EXISTS ( SELECT* FROM ( SELECTCOLUMN_NAME, ORDINAL_POSITION, DATA_TYPE , COLUMN_DEFAULT, IS_NULLABLE , CHARACTER_MAXIMUM_LENGTH, NUMERIC_PRECISION, NUMERIC_SCALE , COLLATION_NAME FROMINFORMATION_SCHEMA.COLUMNS WHERETABLE_SCHEMA = COALESCE(PARSENAME(@t1Name,2),'dbo') AND TABLE_NAME = PARSENAME(@t1Name,1) UNION ALL SELECTCOLUMN_NAME, ORDINAL_POSITION, DATA_TYPE , COLUMN_DEFAULT, IS_NULLABLE , CHARACTER_MAXIMUM_LENGTH, NUMERIC_PRECISION, NUMERIC_SCALE , COLLATION_NAME FROMINFORMATION_SCHEMA.COLUMNS WHERETABLE_SCHEMA = COALESCE(PARSENAME(@t2Name,2),'dbo') AND TABLE_NAME = PARSENAME(@t2Name,1) ) U GROUP BY COLUMN_NAME, ORDINAL_POSITION, DATA_TYPE HAVING COUNT(*) <> 2 ) RETURN 0
I am looking for some SQL Scripts/tool to compare the two sql database and generate the difference results into Excel file. I am not looking for Sync/change scripts.
Example:
Result Type Desc ----------------------- Col1 Column Added Table1 Table Removed
Following an upgrade to SQL Server 2012, our shop's Schema Compare tool (Redgate SQL Compare) is no longer supporting our environment.We are starting to evaluate various 3rd party products to find a possible replacement, and would be interested in what products are favored by other IT shops who do a lot of database work.
Our shop is split about 75% SQL Server, 20% Oracle, and 5% I'll call other. Ideally a product would support SQL Server and Oracle, but our focus is on SQL server right now. On that platform we have ~50 servers spread across DevUATProd environments.In basic terms, we need a tool that can identify schema differences between DBs and generate synchronization scripts to support deploys between environments. Real-time synchronization is not a requirement (nor desirable), as deploys are a gated DBA function in our shop.
Just wondering if there are any tools available for SQL Server 2005 which allow the comparison and scripting of data and schema between two databases. This is so that I can migrate between Dev, QA, and Live easily.
We are getting regular SSDT/VS crashes when doing schema compares (source: project, target: server). Sometimes the compare succeeds but around 80% of the time we get a crash.
We are using VS2013 Update 3 and the latest version of SSDT.
Application : devenv.exe Version du Framework : v4.0.30319 Description : le processus a été arrêté en raison d'une exception non gérée. Informations sur l'exception : System.Runtime.InteropServices.COMException Pile : à System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32, IntPtr)
I've downloaded and installed the latest SQL Server Data Tools for VS 2012. Is there anyway to export the results of the schema comparison into a report in CSV/Html format? I understand that it can generate the sql diff script, but I want a readable report that I can use to show to people.
I just recently updated to SSDT 12.0.50512.0 using Visual Studio 2013 Ultimate. I typically use SSDT Schema Compare to synchronize my schema across multiple databases and different environments. After updating i encountered a major bug while updating our production schema.Typically during schema compare, the compare will prompt me to drop users and user roles from the database as they are not present in the project. I will exclude these so they database users and their roles aren't affected. After the update to SSDT I noticed that schema compare was only prompting me to drop the User, but didn't show anything about the user's roles. Not thinking much of it I went through my usual task of updating all the production databases. I soon found out that this did in fact remove the user roles even though it showed NOTHING in the schema compare UI indicating it would do so.
GO PRINT N'Dropping <unnamed>...';
GO EXECUTE sp_droprolemember @rolename = N'db_datareader', @membername = N'dbuser';
GO PRINT N'Dropping <unnamed>...';
GO EXECUTE sp_droprolemember @rolename = N'db_datawriter', @membername = N'dbuser';
You could say this is partially my fault for not checking the generated script before running it, but after months of this routine task I've never had an issue until this update.i'm not seeing the changes that will happen to my user roles in the schema compare UI?
I'm trying to automate comparing the dacpacs we're generating from out builds against our production server to monitor drift.However, we use scripting variables to define cross database references. The schema compare is showing up all the objects which reference the other database via scripting variable as being different to what is on the server i.e. it reports a change between a table referenced as [$(db)].dbo.Table in the dacpac and db.dbo.Table in the target database.
When I do a comparison in Visual studio between the project and the target database the variables seem to be appropriately replaced and the differences don't show. Obviously this is using a project instead of a dacpac but I'm hoping I can get the dacpac/db compare to behave similarly to the project/db comparison.
Is there a way to define what the scripting variables should resolve to when I run the comparison via msbuild?
Edit: I would prefer not to deploy the dacpac and diff the deployed db against the target database but if that's the only way....
I am importing an existing database into a Visual Studio SQL Server Database project using Schema Compare. The Schema Compare works fine and I updated my project successfully. However, the project won't build because of the existence of 3-part names in some objects:
E.g. I import the database MyDB into a new project MyDB using Schema Compare. The database contains views with queries like this:
SELECT col1, col2. col3 FROM MyDB.dbo.MyTable
When trying to build this project I get errors like:
Error 39 SQL71561: View: [dbo].[vw_MyView] has an unresolved reference to object [MyDB].[dbo].[MyTable]. C:UsersRedirectionrittg2DocumentsVisual Studio 2012ProjectsMySolutionMyDBdboViewsvw_MyView_1.sql
but of course this is a bogus message since the view can clearly read from an object in the same database whether using 2-, 3-part naming (or 4-part naming for that matter).
How can I resolve these errors without editing the objects before running Schema Compare? (there are hundreds of them).
I have created Database projects in VS 2013 using SSDT. I have been mostly successful in creating and building the projects without any errors/warnings.
However for one of the databases in the project, when i do schema compare to apply the changes from a SQL Server Database to a Database Project in VS, code changes are not applied to the database project.
After i select the Update option in Schema compare window, I'm getting the following message
"Target update complete. Press Compere to refresh the comparison."
Even tough the message implies that target database is updated successfully, I do not see the objects i selected in schema compare being added to the target database project.
I see the following warning
"Target update: Could not update script for element 'dbo'"
I have 9 Database projects in the Solution and I'm able to apply changes to 8 of the database projects through schema compare successfully. I get the same warning after schema compare for all database projects.
I have same project level setting for all database projects in the solution. I'm using Visual Studio 2013 Premium Update 5 SQL Server Data Tools 12.0.41012.0
I have a database project where objects have been pulled in from the database using schema compare.
Unfortunately CDC tables which are referenced in stored procedures on the database have not been pulled in by the schema compare & hence I cannot build the project and deploy changes back to the database.
I've got a SQL database running on Windows NT 4 Server (P400, 256 Ram, 8Gb IDE & 18Gb SCSI HDD) and quite a few of the queries are taking a long time to run, and are also using a lot of the processor time. This affects other users who are also trying to query the db. Has anyone got any recommendations for upgrading the hardware spec to improve the overall performance? I presume just add more RAM, and get a dual processor system?
I am a PHP programmer for a small startup. We are storing person records and our MS SQL Server 2000 database has grown to the point where we wish to paginate the data before returning it to my PHP scripts.
I was wondering if anyone has any recommendations on an optimal way to manage this given the following requirements.
- Data must return only X number of rows at a time (user configurable). - Must be able to search by several diffent criteria (name, date, birthday, location, ...)
Also, I was wondering if it is possible to return the total number of existant rows of data as the first row of a MSSQL procedure.
I have a SQL 2005 database containing the location of graphics files. I want to start learning how to write a C# application that will get a path from the DB and display the file. Any recommendations on sites where I can start learning how to do this?
Ok, let me start by saying that I already checked the FAQ. There was one link, but it just seemed to go to a review page with 5 books, with pretty specific themes. So I'm surprised that such a basic topic as book recommendations for SQL newbies wasn't covered.
In my case, I'm not a total newbie. I learned to write SQL queries for work on both Oracle and SQL Server, and I've gotten pretty good at all the basics. So I've got "SQL for Dummies" down cold, so to speak. Now I'm looking to take my query writing ability to the next level, which I guess would be the intermediate level. I'm also looking for books that are specific to just SQL Server, rather than the books about general querying on any DBMS. Speaking of which, just so you all know, "SAMS Teach Yourself SQL in 21 Days" is an Oracle book, no matter what it says on the cover.
It looks like the book "Inside Microsoft SQL Server 2005: T-SQL Querying" comes highly recommended, but I flipped through it on the shelf at a bookstore the other day, and I think it's over my head. It might be a good reference to have around, but I think I'd be totally lost trying to read it from cover to cover.
So does anyone have recommendations for books that go beyond "This is how to do a SELECT, and here's how to do a JOIN", but won't make my head explode?
I do software support for software that works with both Oracle and SQLServer, so I mostly just write queries to look at the data related tothe software. When I first started, I bought a couple of books to learnthe basics, intentionally going with generic books that would help withboth types of databases. I've got the basics down, and now I'm lookingfor a really detailed reference book that goes really indepth intoquerying for SQL Server specifically. Currently, we only work with the2000 version, but we'll be going to 2005 soon, so I think I'd rather gowith a book on 2005, although if you know one that covers thedifferences between them, that would be great. Any recommendations?Besides just writing queries, I'd also like to learn more about SQLServer in general. DBA software support, so I'd like to head mycareer in that direction. I was looking at Microsoft's newcertification path for SQL 2005. Given that my company won't pay tosend me for training, and I really don't want to have to put down$2200+ to pay for a class, I was thinking that I might be able to learnenough on my own to pass the first test and get the MCTS title. Iordered the Training Kit from Microsoft Press for that, which comeswith a 180 day trial of SQL Server 2005 to play with, along with a hugebook. Does anyone have any other recommendations for resources to helplearn this stuff?--Richard
Hello -Anyone have any thoughts on which API to use - ADO or ODBC?I have a fat client written in C++ using MFC ODBC classes to access a Jetdatabase.The app is going to be modified to write to a SQL Server central databasewith multiple users accessing their local copies of the database ( usingreplication technology on the clients side).Most of the performance benchmarks give an edge to ODBC over ADO whenwriting to an Access database. Anyone know of any benchmarks for a c/senvironment?I've seen references that ADO has some client side cursor features forfilters and sorting which are a benefit over ODBC. I'd also like to usethe asynchronous fetch that OLE DB provides and am not sure if this isimplemented in ODBC.Thanks for the help.Bruce
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've recently been tasked with doing some SQL 7.0 administration and was wondering if anyone could recommend a good book to get started. The bulk of my IT experience is in SMS, IIS and messaging so my database fundamentals are pretty weak.
As I see it, it's probably a three-step process to get me at least halfway comfortable - a first book to get some solid general database / SQL-language exposure, a second book that takes the knowledge to a more advanced level and finally a MS-specific book that covers the Microsoft implementation of a SQL server.
Any comments / suggestions would be much appreciated!
I'm a solid SQL developer/dba and have some funds earmarked for training this year. I'd like to expand my dba skills...more specifically, I'd like to become a rock-solid enterprise level dba that has not only a solid foundation of skills but some innovative techniques for managing our corporate SQL servers.
I'm curious if anybody has recommendations on training or conferences that might help me dig into those skillsets for a couple of days.
I am looking for a book that discusses query tuning, index tuning, executionplans, etc. Can anyone recommend something?--BV.WebPorgmaster - www.IHeartMyPond.comWork at Home, Save the Environment - www.amothersdream.com
We have an application that was built and testing using SQL Server Express. One of our clients is deploying it using SQL Server Standard and plans to put the data files and log files on separate disk volumes.
In allocating the available disks to the volumes, they are looking for a recommendation on how big the log file volume versus the data file volume should be. Over time there will several years worth of data in the data files. I assume the log files need to be at least big enough to log all the changes between back-ups. Are there any general rules of thumb? Or whitepapers that discuss the trade-offs?
I'm trying to get a better idea of how I should set some of the SSCE connection properties. I will be deploying the application on a WinCE5 board with a 4G flash storage card and 512MB RAM. The application must run 24/7 with a medium amount of traffic. At any given point I expect up to 3 connections to the same database. I'd really like to keep performance high without risking any database corruption issues. As such, I need to make sure my connection properties are optimized.
I read from Joao's article that setting DBPROP_SSCE_MAXBUFFERSIZE = 1024 gave a considerable performance increase, while anything higher gave diminishing returns. Is this for a certain amount of RAM, or is it uncorrelated to RAM size?
What's the best practice for specifying DBPROP_SSCE_TEMPFILE_DIRECTORY and DBPROP_SSCE_TEMPFILE_MAX_SIZE? Is it possible in WinCE5 to directly put it in RAM? How big do these temp files get?
I've read of some bad experiences with autoshrink. Are there any reasons not to set DBPROP_SSCE_AUTO_SHRINK_THRESHOLD to 100 if the database will be compacted regularly?
Any other advice for the more obscure settings such as DBPROP_SSCE_FLUSH_INTERVAL or all the lock settings?
I am in the process of creating a user interface that will give the users a list of reports to choose from. I wanted to write an interface in ASP .NET with C# to pull information for different reports from the reporting services web service. I have successfully done this with C# Windows Form. The project requires it to be web-based.
Problem is, I am new to web forms and would like a recommendation for reference materials to help me program ASP .NET with C# and using the web service. I am still learning ASP .NET and C#, so I would like something fairly basic.
This really isn't a SQL Server specific question, but more tword SQL in general. I am pretty good at SQL, being able to perform joins on several tables at one time. I am looking for more challenges in SQL though as I want to learn more and to rise to the next level. Can anyone recommend some good resources to me? It would be challenging to me to learn how to do more complex queries involving three or more tables. Ralph

I want to build a SQL testing environment in an active/active setup. Any recommendations on what I could use if I want to set up the most bare-bones system. I want to do it as cheaply as possible.
