According to this question and this answer hsqldb
datasource can be changed to work with enabled MySQL compatibility mode using this connection URL:
jdbc:hsqldb:mem:testdb;sql.syntax_mys=true
My question is more specific: how to turn this mode when using Spring's embedded-database? So it's just:
<jdbc:embedded-database id="dataSource" type="HSQL" >
<jdbc:script location="classpath:schema.sql"/>
</jdbc:embedded-database>
I have no idea where to place in this configuration compatibility mode parameters. Any ideas?
