Introduction

Usage

java com.agimatec.dbhistory.HistoryGeneratorTool
  -conf historyConfig.xml
  -catalog catalog.xml 
  -ftldir templates 
  -dbms dbms 
  -ftl templateBaseName 
  -destdir targetDirectory

Options

• -help (optional) print help
• -conf (optional) name of configuration file, default is historyConfig.xml
• -nconf (optional) use NO configuration file
• -nout (optional) do NOT write a default output file (let templates handle output file names)
• -catalog (required) path of catalog file to read (xml or dump), created by DDLParserTool
• -ftldir (optional) default: templates. Base directory with .ftl templates (in subdirs)
• -dbms (required) subdirs of ftldir with database-specific templates, e.g. oracle, postgres
• -ftl (required) can appear multiple times. the template base name (without .ftl suffix)
• -destdir (optional) default: target. Directory to write output files to.
• +key=value A property key and value that the template can access with ${key}

Example: +tablespace=TEMP in template: ${tablespace}

You can provide multiple properties to the template this way.

Accessing static methods inside the freemarker template

The template can access a predefined property "statics" to invoke static methods. See freemarker documentation for further details.

Example: prints milliseconds into template by invoking System.currentTimeMillis();

${statics["java.lang.System"].currentTimeMillis()}

Property statics is BeansWrapper.getDefaultInstance().getStaticModels().

Example

The example syntax demonstrates the invocation of the HistoryGeneratorTool from the InvokerTool with ant (or the maven-antrun-plugin). You can imagine the native java call, can't you?

<java fork="true" failonerror="true"
   classname="com.agimatec.database.InvokerTool"
   classpathref="maven.compile.classpath">
 <jvmarg value="-Dfile.encoding=UTF-8"/>
               
 <arg line="{ com.agimatec.dbhistory.HistoryGeneratorTool "/>
 <arg line="-conf historyconfig.xml"/>
 <arg line="-catalog target/my-catalog-postgres.xml"/>
 <arg line="-dbms postgres -destdir postgres/setup "/>
 <arg line="-ftldir templates"/>
 <arg line="-ftl history-schema -ftl history-triggers }"/>
</java>

This generates the history-schema.sql and the history-triggers.sql file for the catalog "my-catalog-postgres.xml".

To do the same for oracle, just use -dbms oracle instead and provide the catalog of your oracle database.
