We currently have a Database Project, which we wrote a WIX Installer for to deploy it, using VSDBCMD means we are able to do a comparison against the current database, and do an update or fresh install when required.
However we have found some issues with this:
1. We need a separate Database installer that needs to be executed on the SQL server (if you want to do it from another server, we found can only be done if it is a domain server and u use a account that has access to both systems and is a sysadmin on the sql).
2. Compact framework has to be installed for VSDBCMD to work.
We are now at a point where we would like to integrate our Database installer into our main installer, this means that most of the time we will be installing from a different system then the sql machine and would like to be able to use an SA account to install the database.
We have tried out SQLCMD, but that doesn't seem to be able to do a comparison on an already existing database.
I would like to know that if a) it is possible to use SQLCMD to do a comparison and how that would work, or b) if SQLCMD is not an option, can VSDBCMD work with an sa account, rather then a domain account?
Thanks
SQLCmd can only execute SQL commands or batches on a database server - it assumes the person writing the script knows the current state of the database and the script will be executed as if it was run in SSMS.
If you want to use the declarative development powers of Visual Studio then you need to use VSDBCMD to deploy them onto your server machine. If you use a connection string in the command line that doesn't use integrated login, you should be able to execute it from your client machine. For example:
"Data Source=$Server;User ID=$UserName;Password=$Password"
Then a SQL Server login for $UserName would suffice.

I am using SQL Developer to construct a PL/SQL file for Oracle DB updates and I want to test them out, but I dont have UPDATE privileges. Is there some type of test mode that would pretend I do and save things locally? Or do I have to export the data I need into a local DB and test it there?
You'd need to have a database where you do have update privileges to run your test or some way in your environment to cause your script to be run (i.e. sending it to a DBA to run against a lower environment, checking it in to your build tool to have the build tool run the script against the lower environment, etc.). SQL Developer is just a client that connects to other databases, it doesn't include a database that you could run the script against.
Hi I've been reading this instruction:
http://www.oracle-base.com/articles/10g/oracle-data-pump-10g.php#NetworkExportsImports
From my understanding, I need to login my local oracle database, establish a database link to the remote oracle server, then use expdp to export database to local.
But now I only have sqlplus installed in local computer, how can I expdp to local?
Thank you very much.
You can't. expdp only works locally. The database link is just a kludge to make the Oracle instance on your current machine be able to see the data in the other database. If you truly need a remote back up, your only non-custom or third party option would be exp, but that's deprecated. (I'm not aware of any third party solutions, either.)
Another option to consider is running the command on the remote server and then using something else to copy the file. This is more feasible if you run a Linux server, since you can likely use SSH and SFTP.
You could try Oracle Express on your local machine if you want to pursue the database link option. That is a very heavy solution, of course.
(In all honesty, I have had endless troubles with expdp anyway. Well, more with impdp, but still. The data dump/restore situation in Oracle is not very good, in my opinion.)
I have a machine running Oracle 10g server in windows server 2008. I want to take backup of the database. I also want to take backup of some files saved on hard disk by oracle server that users have uploaded using my website.
I can connect to the Oracle server using sql developer and sqlplus. I can run sql queries on the server.
In order to take backup of database I have to run the command "exp" (this is the only way of taking backup of databases that I know). There might be some other way but there is another problem because of which I must run dos command. That problem is to take backup of files. These files are stored in c:\mydir. The folder mydir is not accessible anyway through web and is not a shared folder.
I have tried running "host " in sqlplus after connecting to oracle server, that is at "sql>" prompt. The command ran successfuly but at local machine, not at oracle server.
Edit: The "host" command is provided by sqlplus and is not an oracle command, means cannot be used in a query. Sqlplus even when connected to remote machine run the "host" command at local machine.
The target is to either make sqlplus run the "host" command at remote machine, Or run the dos command from inside a pl/sql query (independent of sqlplus).
In addition to what Justin has written:
If you want to take a logical snapshot of the database the new DataPump tool is preferred over the old (and deprecated) exp tool.
DataPump is a commandline tool (expdp) but also has a SQL API through Oracle packages and procedures.
The Data Pump API (including examples)
DBMS_DATAPUMP (reference)
But if you want a "real" backup you should look into RMAN
It is possible to create a Java stored procedure on the database server that executes an operating system command on the Oracle server. But it would be extremely unusual to use the export utility to backup a database-- that only creates a logical backup not a more appropriate physical backup. And it would be extremely unusual to run a backup by connecting to the database via SQL*Plus and spawning a job on the server operating system. It would make much more sense to create a job using the Windows scheduler on the database server that ran whatever export commands you want to run.
I have an ASP.NET MVC 3 application using an Entity Framework (4.3.1) Code First database. Now I would like to create a comprehensive zip file containing the database, the application package generated by Visual Studio 2010 and a script to deploy everything to a Windows 2008 server with IIS7 and SQL Server 2008 with a prepared (but empty) database.
I don't foresee any problems with the deployment of the application package, but I'm unsure of what approach to use in deploying the database. The target environment already has an empty database that's been assigned to me, but I've been told that dropping and creating the database is fine.
From what I've read, I can do a straightforward copy of the .mdf and .ldf files to the server and then setup my connection string to point to that specific file but this approach sort of ignores the database that has already been created (or at least named) for me. The other approach would be to use the the existing .mdf to create the database on the server with a script. My only issue here is that I would like to keep the database name assigned to me.
I usually connect to my development database locally using SQL Management Studio and right-click the database, choose Tasks -> Generate Scripts. Then I select the entire database or just the tables I'd like to keep, click next, then click the Advanced button and make sure that I am scripting out "Schema and Data", and then generate a sql script that I can run on the production database, therefore keeping the table structure and the data that was in the dev database. Obviously, if you don't want to keep the data then just script out the Schema only. Then, point your application's connection string to the new production environment database and you're good to go.
I have an installer wizard thing called 'install creator'. I want to include my mySQL database into the installer or find another way that the user, upon installation, can just use my database. Prob is-not everyone has MySQL installed on the computer and even then, the user doesn't know the name of the database or my password. Somehow the database must be created automatically upon install, and for my purposes, some of the tables created. How can one do this. Thanks
If you are just using MySQL as a local storage engine, as it seems to be what you are doing, then you should consider using Sqlite with JDBC, instead of MySQL. MySQL is really intended to be used on a server, where information from multiple users is stored, and where the database is accessed only indirectly through the programs that you create that run on the server. You could, in theory, package up MySQL and MySQL Connector/J which lets JDBC talk with MySQL; however, MySQL is a pretty big beast, and I don't think it's nice to do that to your users (also, don't forget that they might already have MySQL installed, and if you were to install MySQL for the first time, you would effectively be forcing them to use your root password). Unlike MySQL, sqlite is intended to provide the structure of SQL for use with lightweight, local file storage.
