Wrong Oracle SQL script generation from EJB QL

Question

I have this query

SELECT acc.Id 
  FROM Auth as auth, AccId as acc 
 WHERE acc.ownId.Id = auth.Id 
   AND acc.disabled = 0

Which appears to have been generated correctly:

org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLSyntaxErrorException: ORA-00904: "T1"."A_ID"."T1"."A_ID": invalid identifier

Obviously acc.ownId.Id was not generated properly.

How could this have happened?

Answer 1

Please show your table definition, it makes it easier. Provide your table information and we can take a look at the create table clause.

acc.ownId.Id is wrong identifier for a column, if you dont put " " around it!

Check the correct column.

maybe

acc.ownId only? or acc."ownId.Id" ?

IF your column name was created as:

Create table AccId (
...
"ownId.Id" int,
...
);

It works, but I would not recommend this kind of naming.

Then of course you will need to wrapp it with " " if you use it in your query.

i.e.

WHERE acc."ownId.Id" = auth.Id
