I have a 2 MS SQL 2005 databases,a TEST and DEV database. Now our developer added some extra columns,tables etc in the DEV database.This created differences in the TEST database.is there a script i can write tha can tell me what the changes where in the DEV database between certain dates...i found a couple of tools but they are quite basic and dont really generate change scripts etc. Also tried the change script function in management studio but it seems to be working when the change is first made and not later.
Appreciate your thoughts.

redgate SQL Compare is a good tool to check for differences between databases and even sync them.
However, if you need to do this for free, try this: within in SQL Server Management Studio do the following:
1) script the entire schema of TEST to a file, look here if you don't know how
2) repeat step #1 but for the DEV database
3) diff the files using something like Beyond Compare, should have a 30 trial
I wrote dbscript, and one of its features is to compare two database schemas and create a migration script.
What you need is a way to manage changes to your database schema and then apply them in a controlled and consistent manner. Moreover, you need a single authoritative source for the database schema.
For all this, check out Wizardby:

I have a creation script for a SQL Server database and beside it I have a test script
My test Script should compare the result of my original script and the database and let me know if it is a match
I need to store the resulting script in a repository.
I've already got a script and the database. It's not hard to write the test script, but I want an app that automates the process.
I've already got Redgate tools and I heard it can make the job for me, but how? If not, are there any other tools that could do such a thing?
If you're looking to compare the structure of the two databases this can be done using Redgate SQL Compare.
Set the location of your script as a "Scripts Folder" source within the tool.
Set the database where you have run the script as the target.
Run the comparison. This will show you if there are any differences.
Generate a report of the differences which can be referred back to at a later date. (https://documentation.red-gate.com/display/SC12/Generating+a+report)
To automate this process you can make use of the SQL Compare command line. (https://documentation.red-gate.com/display/SC12/Simple+examples+using+the+command+line)
Full disclosure: I'm a developer at Redgate for SQL Compare.
I'm not sure if you are searching something to compare your data or the structure of your databases.
If it's for the structure (like Red-Gate SQL Compare and not SQL Data Compare), you can install SSDT (Microsoft SQL Server Data tools - It's free and available for visual studio).
With SSDT you will be able to create a database project and compare 2 databases structures.
Here is a quick presentation that I found on youtube:

You can completely automate comparison and reporting with Apex Diff. Not sure which SQL Server are you using, but it's free for SQL Server Express.
Here is a step by step tutorial, which you should follow with one difference - set Script folder as data source:

I am looking for information regarding Visual Studio 2013 and working with SQL Server projects using VS 2013. We are currently working on a project where were're using a database that already exists and is used by an ERP application. We're creating SQL Scripts that would alter and create fields on a table on the target database.
Now, we're not looking to "publish" those scripts, but create postdeploy scripts instead, which contains all the necessary SQL scripts in the order they need to be run. Everything is working fine. When we build the project, we get a fresh copy of the PostDeploy.sql script file that we run across a target database.
At the moment, the script looks at a table, if the column that needs to be added exists, it DROPS it and then recreates it. This is fine for the testing phase, but once we go live, there will be several stages of the databases that the code needs to be tested on. The column may already exist from before and in that case, we wouldn't want to DROP that column, instead, we want to do schema and data level compare and just get over the objects that are DIFFERENT, so that the column doesn't need to be dropped, instead just "updated". I hope I am not being vague when I ask this question.
I found this video: https://www.youtube.com/watch?v=AuVpmu9CKRY and I am not sure if that is what I need to do? I would love any suggestions from you guys..
Have a wonderful day!
Well, this isn't really the best use for SSDT/DB Projects. Ideally, you'd want to pull the schema into a project and tweak that project to look the way you want. Rename columns, change types, etc. Because it sounds like this is a 3rd party app, you'd want some environment that can serve as your baseline - when you run whatever upgrade script is sent by the vendor, it goes against that environment. You'd then want to pull the appropriate changes into your project.
Once you have a project that looks the way you want, you use the publish option against your target database. In your case, I'd likely recommend generating a script. If you're in the VS environment, you can take a look at both the script and a summary of what will be changed.
For data compares, I'd really consider something like Red Gate's SQL Data Compare (pro edition if you can). You can set up a data compare against your baseline and automate pushing the data changes. You can do that through post-deploy scripts, but you'll need to hand-code the data inserts, updates, and deletes yourself.
I've blogged about SSDT before and that may give you some ideas. Jamie Thomson has also written quite a bit about Database/SQL Projects and inspired quite a bit of what I've done.

Is there a tool that will let me generate a single script containing all tables and views? Sql Publishing Wizard drops everything (so all data is lost) and recreates it. It does have an option to not drop, but in that case, it doesn't update tables that exist (if any columns have changed).
In SQL Server Management Studio 2008 you can right-click on a database in the object explorer, go to Tasks > Generate Scripts..., and that will give you the option to choose not only what object types you want to script, but whether or not you want to script the drop as well.
When you are making changes to existing tables, you should be writing alter table scripts to make the change and then putting them in source control like any other code. Then when you deploy a set of changes, you run the scripts you created for that deployment.
Otherwise, yes use SQL compare.
Should you look at the Red Gate products specifically SQL Compare. They'll handle any situation you could need concerning script generation and database synchronization. (You can get a trial license too, to try it out and see if it is what you need.)
Have a look at this tool can be used which has the capability to generate the create and drop scripts for the SQL server objects, provided in a configuration file.
This tool uses the same mechanism as SSMS tool uses to generate the script.
SQL Server Script Generator Tool (via C#)
Have a look at these:
WinSQL (Lite edition is free, other versions are reasonably priced + free trial)
OpenDbDiff (free)
You can also check out MyDbUtils which can create scripts for:
Stored Procedures
Functions
Views
Triggers
My Application Database Without Project and without Source safe, i planned to make my DB to be as project and add it to TFS, but I have no idea how to script the stored procedures, Triggers, Views, Functions, and what is the best practice to Make Update Script for All My stored procedures, Triggers, Views, and Functions to My customers DB.
The best procedure (IMHO) is to manually maintain a strict version of your schemas. Then when you need to make changes you write a delta script to move from one version to the next. I suggest you write the DDL scripts by hand -- you can make them concise and comment them.
You can use a tool like Visual Studio Team System for database architects, take a look at Running static code analysis on SQL Server database with Visual Studio Team System for database architects it will show you how to import the data, disregard the static code analysis that comes later it does not apply to your question
I've found a good way to get SQL scripts into SCM from an existing database is to use SMSS's "export all to script" option or whatever it's called, can't remember now.
Then every other change you add the change script into your SCM with a different version number in the file name.
Every release (or set cycle depending on your development/release methodology) you apply all change scripts, then re-script the entire database, tag it, and start again.
The best way to do it - save the database in TFS as set of database creation script, i.e. MyTable table should be added to TFS as MyTable.sql file (CREATE TABLE...) etc. We are using SQL Examiner to do this - see the following article: How to keep your database under version control
We are working with SVN and I never tested SQL Examiner with TFS, but I know that the tool supports TFS.
I was wondering if there is a way to automatically append to a script file all the changes I am making to my columns, tables, relationships etc...
The thing is I am doing a lot of different changes on a TEST db and the idea will be to apply this change script when I move the test db to production... hence keeping production data but applying all schema and object changes.
Is there an easy way to do this? Can it also migrate database diagram changes?
I have seen how you can create a change script each time I do a change but this means I have to copy and paste into a master file. Actually pretty easy!
I was just wondering if I was missing something?
Do not make changes to the test server using the UI. Write scripts and keep them under source control. You can test your scripts starting from backups of the live data and you can tune yoru scripts untill they achieve the desired result. Then you can check in the scripts for reference and later apply them on the live server. See this article Version Control and Your Database.
BTW, check out the SSMS toolpack, I think it may do what you want (I'm not sure). My advice stand none the less: version your schema, use explicitly created/saved scripts, use source control.
There's no way to directly generate a "delta" script in SSMS.
However, if every time you publish changes, you script out the entire database, including data, to SQL using the SQL Server Database Publishing Wizard you should be able to extract diffs between the versions and get your deltas that way.
If money is no object, you can purchase Visual Studio Team System Database Architect edition and use its fantastic database comparison tools to generate and version control exactly the diffs you want.
Try using TableDiff , that came with SQL Server 2005.
SQL Server 2005 TableDiff Utility
tablediff Utility
We have the process where when a developer gets done with a change, they then script it out and check it into Subversion. In Subversion we have a folder for Tables, Stored Procs, Data, etc. They script it out so it is repeatable (i.e. don’t insert the new data if it is already there.) This is important to do anyway so you keep the history of changes for a given object in the database.
In the past, we would just enter each of the files that we wanted scripted out into a text file (i.e. FileListV102.txt). When we were ready to make a release we would do “get latest” on all of the files (from VSS back then.) We then had a simple utility that would read the “file list” file and open each of those files in turn concatenating them into an output file. That is pretty easy to code.
We outgrew that and now we have a release management tools (which can be found here and will be on sale mid September), that takes all of the files and creates a big SQL script file out of it. It does it in the order that you would expect based on the folder names – so files found in the "Tables" folder are done before those in the "Data" folder, etc.
Either way, once you are done you have a big SQL script file that you can then apply to a fresh copy of production and that is what you test against.
I know I'm way late to the party, but I just wanted to add that there are tens of third party products out there. Some are very good, some are very cheap or free, and some are a mixture. I listed 22 here:

We have been using a relatively new software called Kal Admin.
It has Change Management feature and let distributing selected changes to other databases very easily. We used to do it by comparing two databases but it not satisfy our need for change tracking.
BTW Kal Admin has Metadata and data compare capabilities as well.
