Hello All,

I want to ask if someone know how to write the query inside @NamedQuery.

The query is joining 3 tables S below:
compound_property
logical_operator
rtp_goal
rtp

-rtp is the parent table for rtp_goal.
-compound_property and logical_operator are both independent table which referencing inside rtp_goal table.

My plain SQL query is like below:
SELECT cp.compound_property_name,lo.logical_operator_name,cp.compound _property_value,cp.component_property_unit
FROM ComponentProperty cp,LogicalOperator lo,Rtp r,RtpGoal rg
WHERE cp.compound_property_id = rg.compound_property_id
AND lo.logical_operator_id = rg.logical_operator_id
AND r.rtp_id = rg.rtp_id;

I tried to insert the above query inside @NamedQueries but it provides error as below:
