Modify values in mysql-sample-command-line.bat. Make sure mysql.data.dll is placed in GAC or in the same directory as DbUpdater.exe. Connector binaries can be downloaded from here – http://dev.mysql.com/downloads/connector/net/6.1.html
My invitation code for SQL Azure CTP finally arrived. I had been waiting for this. You can create a database in from the SQL Azure Management page, shown above. After you have created the database, of course, you can use DbUpdater with your SQL Azure databases. Here is the command-line : DbUpdater.exe ..\SqlScripts /server:”tcp:SERVER.ctp.database.windows.net” /db:DATABASE /user:”USER@SERVER” /password:PASSWORD /confirm:true And you will need this DbUpdater.exe.config file : <?xml version=”1.0″ encoding=”utf-8″ ?> <configuration> <appSettings> <add key=”file-prefix” value=”db” /> <add key=”file-extension” value=”sql” /> <add key=”schema-versions-name” value=”schema-versions-table.sql” /> <add key=”baseline-name” value=”baseline.sql” /> <add key=”post-script-prefix” value=”post” /> <add key=”post-script-always-apply” value=”true” /> <add key=”exe-file” value=”C:\Program Files\Microsoft SQL Server\90\Tools\Binn\SQLCMD.EXE” /> <add key=”exe-args” value=’-U %UserName% -P %Password% -S “%ServerName%” -d %DbName% -i “%SqlFile%”‘ /> <add key=”dialect” value=”NHibernate.Dialect.MsSql2000Dialect” /> <add […]
DbUpdater (version 1.3 onwards) can be used with sqlite3. Review the files included in DbUpdater-sqlite3.zip 1. DbUpdater.exe.config must be modified. Note changes to the following keys – exe-file, exe-args, dialect, driver_class, connetion_string. 2. SchemaVersion.hbm.xml must be modified. The ‘class’ attributes value for the ‘generator’ of ‘id’ must be changed to ‘identity’. No other changes are needed here. 3. \SqlScripts\schema-version-table.sql is modified. Note that the datatypes of all columns are changed to TEXT, except for SchemaChangeId, which is changed to integer primary key. integer primary key is used for auto-incremented columns in sqlite. 4. \SqlScripts\baseline.sql is modified. Note the use of current_timestamp function. The actual sql syntax in this file must conform to sqlite dialect. 5. All other .sql scripts in […]
By popular demand, DbUpdater is now up on the sourceforge. Latest download (v1.2) is now available from there.
Version Aware Database Schema Deployment Download : DbUpdater v 1.4 (License:GNU General Public License version 3 (GPLv3)) Copyright © 2008 : Ash Tewari www.tewari.info DbUpdater is a free tool that helps you implement the database schema version control system described by K. Scott Allen in this set of articles : Three rules for database work The Baseline Change Scripts Views, Stored Procedures and the Like Branching and Merging Usage : First read the articles listed above. The file prefix for change scripts is “db”, by default. You can change it in the config file. DbUpdater supports the baseline script as well as post-scripts. Make sure the database you are going to put under version control is already created. Specify the […]
It is essential to treat database schema as source code and apply all the norms and best practices applicable to it. From what I hear and read, database schema version control is non-existent in too many projects. Various techniques to accomplish version control of database schemas have been discussed and published. Martin Fowler and Pramod Sadagale has written a comprehensive article on Evolutionary Database Design. It is a must-read for everyone involved with database development. K. Scott Allen writes in detail about an excellent system here – Versioning Databases – Change Scripts. This approach is sufficiently light-weight (for my taste) and provides complete control over the whole process. I am providing a free tool here that you can use to […]
