Can I concat two variables in WSO2 Dataservice?
Something like
<config id="DBConf">
<property name="url">$SYSTEM:DB_URL$;$SYSTEM:DB_NAME</property>
</config>
I don't think you can add multiple environment variables. But as a workaround maybe you can concat these two variables where you are exporting these environment variables.
export FULL_DB_URL=$DB_URL;$DB_NAME
then in dataservice
<config id="DBConf">
<property name="url">$SYSTEM:FULL_DB_URL</property>
</config>
