Class GeneratedColumnChange

  • All Implemented Interfaces:
    Cloneable, liquibase.change.Change, liquibase.change.ChangeWithColumns<JsonEnabledColumnConfig>, liquibase.ExtensibleObject, liquibase.plugin.Plugin, liquibase.serializer.LiquibaseSerializable
    public class GeneratedColumnChange
extends liquibase.change.AbstractChange
implements liquibase.change.ChangeWithColumns<JsonEnabledColumnConfig>
    Extension used to a column whose values are generated from a property of a JSON file stored in one of the table's columns.

    Example configuration in the changelog: 

         <databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                    xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
                    xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
                    http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.1.xsd
                    http://www.liquibase.org/xml/ns/dbchangelog-ext
                    http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd">

     <changeSet author="keycloak" id="some_id">
         ...
         <ext:addGeneratedColumn tableName="test">
             <ext:column name="new_column" type="VARCHAR(36)" jsonColumn="metadata" jsonProperty="alias"/>
         </ext:addGeneratedColumn>
     </changeSet>
    The above configuration is adding a new column, named new_column, whose values are generated from the alias property of the JSON file stored in column metadata. If, for example, a particular entry in the table contains the JSON {"name":"duke","alias":"jduke"} in column metadata, the value generated for the new column will be jduke.
