We have some apps running on an Oracle 8i database. Wow, almost 10 years old. Cayenne 2 has been working great. When I tried updating to Cayenne 3, I got a syntax error in a particular bit of SQL with a JOIN. This isn't an urgent problem for us but I thought I'd mention it.
We have an Employee entity with a many-to-many relationship to Role. With a join table called Employee_Role. List roles = employee.getRoles(); Role role = roles.get(0); The first fetch works but resolving the first element generates this SQL: SELECT DISTINCT t0.* FROM ROLE t0 JOIN EMPLOYEE_ROLE t1 ON (t0.ROLE_ID = t1.ROLE_ID) WHERE t1.EMPLOYEE_ID = ? [bind: 1:312] Oracle 8i doesn't understand that JOIN...ON syntax and throws: java.sql.SQLException: ORA-00933: SQL command not properly ended The same code works fine on PostgreSQL with almost the same generated SQL.
