How to assign two columns to one index in Lquibase datamigration.xml file for Derby DB. I have used following codes which work fine with oracle and MSSQL. but derby is creating two rows with same index name.
<createIndex indexName="idx_group_name" tableName="rights" unique="true">
<column name="name"/>
<column name="group_name"/>
</createIndex>
Derby DB was complaining while uploading same data from csv file. Issue was resolved by not uploading csv file from dbmigration.xml file. Thanks
