Summary: EJB-QL - missing in generated SQL
Initial Comment:
EJB-QL:
SELECT DISTINCT OBJECT(r)
FROM record r,
IN (r.fields) f1,
IN (r.fields) f2,
IN (r.assns) assn
WHERE f1.attrName=?1
AND f1.attrValue=?2
AND f2.attrName=?3
AND f2.attrValue=?4
AND assn.dataSourceName<>?5
GENERATED SQL:
SELECT DISTINCT t0_r.id
FROM record t0_r, field t1_f1, field t2_f2,
datasourcerecordassn t3_assn
WHERE t1_f1.attr_name = ?
AND t1_f1.attr_value = ?
AND t2_f2.attr_name = ?
AND t2_f2.attr_value = ?
AND t3_assn.ds_name <> ?
AND (t0_r.id=t3_assn.record_id
AND t0_r.id=t2_f2.record_id)
BUG: there is a join missing between t1_f1 and t0_r
(t0_r.id=t1_f1.record_id)
CORRECT SQL:
SELECT DISTINCT t0_r.id
FROM record t0_r, field t1_f1, field t2_f2,
datasourcerecordassn t3_assn
WHERE t1_f1.attr_name = ?
AND t1_f1.attr_value = ?
AND t2_f2.attr_name = ?
AND t2_f2.attr_value = ?
AND t3_assn.ds_name <> ?
AND (t0_r.id=t3_assn.record_id
AND t0_r.id=t2_f2.record_id
AND t0_r.id=t1_f1.record_id)

This fix has broken one of our queries:
The ejbql is:
select distinct object(p) from User as u, in (u.userRoleSeqs) as rs, in
(rs.role.rolePrivs) as p where u.loginId = ?1 and p.pcode = ?2
The generated SQL used to be:
SELECT DISTINCT t0_p.pcode, t0_p.description, t0_p.greyOut FROM USERS t1_u,
USER_ROLES_SEQ t2_rs, PRIVS t0_p, ROLE_PRIVS t3_rs_role_rolePrivs_RELATION_, ROLES
t4_rs_role WHERE (t1_u.loginId = ? AND t0_p.pcode = ?) AND (t2_rs.roleid=t4_rs_role.id
AND t4_rs_role.id=t3_rs_role_rolePrivs_RELATION_.roleid AND
t0_p.pcode=t3_rs_role_rolePrivs_RELATION_.privcode AND t1_u.loginId=t2_rs.owneruser)
and is now:
SELECT DISTINCT t0_p.pcode, t0_p.description, t0_p.greyOut FROM USERS t1_u,
USER_ROLES_SEQ t2_rs, PRIVS t0_p, ROLE_PRIVS t3_rs_role_rolePrivs_RELATION_ WHERE
(t1_u.loginId = ? AND t0_p.pcode = ? AND (t1_u.loginId=t2_rs.owneruser AND
t6_rs_role.id=t3_rs_role_rolePrivs_RELATION_.roleid AND
t0_p.pcode=t3_rs_role_rolePrivs_RELATION_.privcode AND t2_rs.roleid=t6_rs_role.id)
which fails completely because there is t6_rs_role in the FROM clause.
The relationships are:
Privs
�*^
��|
Roles
��^
�*|
UserRoleSeq
�*^
��|
Users
which hopefully is not mutilated too much when I submit this.
