com.agimatec.dbmigrate.AutoMigrationTool

All Implemented Interfaces:

MigrationTool

public class AutoMigrationTool
extends BaseMigrationTool

Automatical database migration program for Agimatec GmbH

 Features:
 01- detect from-version from database or config-file
 02- execute sql-scripts or commands from a config file for
     all files that belong to versions later than "from-version".
 03- automatic script detection and sorting.
 04- can stop execution at "to-version", if set in config-file.
 05- supports conditional execution in sql-scripts (-- #if #endif syntax)
 06- support conditional execution in config-files (list-tags)
 07- supports enviroment variables in sql-scripts ( ${variable} syntax )
 08- supports connect commands in SQL-scripts
 09- a) supports local-enviroment variables per config-file of each migration version,
     b) environment variables per migration config,
     c) all JVM System-Properties are accessible as environment variable default
 10- supports Simulation-mode "with jvm parameter -Dsim=true" to check
     behavior before affecting the system.
 11- supports subscripts (@scriptname.sql; syntax)
 12 - supports db_version upgrade with setVersion(dbversion)-method
      or -- @version(dbversion) script-directive
 13 - runs all scripts as files or as classpath resource
 14 - (optional) automatically create db_version table
 15 - (optional) automatically set version in db_version table after script execution
 16 - can be integrated into grails project (see plugin viaboxx-dbmigrate)
 17 - runs sql, xml or groovy script (auto-detect by file suffix)

 final String sim = System.getProperty(SYSTEM_PROPERTY_SIM);
 sim = "true"|"yes" :: simulation, echo execution sequence into log, but do not invoke any script
 otherwise (=default) :: execute scripts/java in sequence
