How can i express this SQL query in HQL if we say i have the correct mappings, dtos(pojo) and configurations files...
select * from sig_tc_contraloria_objetivos o
inner join sig_tc_contraloria_iniciativas i on o.id_objetivo = i.id_objetivo
inner join sig_tc_contraloria_acciones a on i.id_iniciativa = a.id_iniciativa
where a.id_organizacion = 8;
I expect as a result a List of objetivos(Parent) -> Iniciativas(Child) -> Acciones(Child)
I was trying in this way:
String sql = "select distinct p from SigTcContraloriaObjetivos p join p.children c join c.children b where b.idOrganizacion = 8";
assuming correct mapping and configuration the following should work
String sql = "select distinct p from SigTcContraloriaObjetivos p join p.children c join c.children b where b.idOrganizacion = 8";
the difference is in the where clause. You had an and right after where and that's illegal syntax.

SQL Code: SELECT Alan1, Alan2, Alan3, Alan4, A.A_Ihbar_Sayısı, B.B_Ihbar_Sayısı, C.C_Ihbar_Sayısı FROM A INNER JOIN B ON A.Alan4 = B.Alan4 AND A.Alan3 = B.Alan3 AND A.Alan2 = B.Alan2 INNER JOIN C ON B.Alan4 = C.Alan4 AND B.Alan3 = C.Alan3 AND B.Alan2 = C.Alan2;
I get error in query expression . (Error 3075).I'm sure I didn't make a syntax error. How can I fix this situation?
MS Access has arcane syntax requirements, such as parentheses in the FROM clause for multiple JOINs:
SELECT Alan1, Alan2, Alan3, Alan4, A.A_Ihbar_Sayısı, B.B_Ihbar_Sayısı, C.C_Ihbar_Sayısı FROM (A INNER JOIN
B
ON A.Alan4 = B.Alan4 AND A.Alan3 = B.Alan3 AND A.Alan2 = B.Alan2
) INNER JOIN
C
ON B.Alan4 = C.Alan4 AND B.Alan3 = C.Alan3 AND B.Alan2 = C.Alan2;
i'm performing an sql request, but in that request I would like to get all the field from the mission table...but if I write m.* inside the select...symfony told me the Mission entity doesn't have any * field. How can I translate that without getting all the field...because I got more or less 40 field in that table so...Thanks

I've given this relational scheme and following task:
Inner Join: Return a list of professors, which gives
'lehrveranstaltung' of the 'fachbereich' with the name 'informatik'.
* print 'vorname', 'ho_name', 'lv_name'
* output should sort surnames in ascending order and if they're the same in descending order
* identical lines should online shown once
now I came up with following query:
select distinct
v.vorname,
h.ho_name,
l.lv_name
--print wanted, only once
from
vorname v,
hochschulangehoeriger h,
lehrveranstaltung l
-- from these tables
inner join fachbereich f on f.fb_name = 'Informatik'
-- only the 'informatik' events
inner join prof_haelt_lv on l.lv_nr = pl.lv_nr
-- make sure 'lehrveranstaltung' is from a professor
inner join mitarbeiter mit on pl.pers_Nr = mit.pers_Nr
-- make sure dude is a prof
where
mit.ho_nr = h.ho_nr
and
mit.ho_nr = v.ho_nr -- give only names from prof
order by
2 asc,
3 desc; -- order rules
I think this works for me (can't test it properly). But when I look at it I'll wish that I came up for a bether solution since this looks kinda ugly and wrong for me.
Is there a bether way of doing this? (Have to use inner join)
Based on the table you have, you may use the following SQL statement
SELECT DISTINCT v.vorname,
h.ho_name,
l.lv_name
FROM vorname v
INNER JOIN hochschulangehoeriger h
ON v.ho_nr = h.ho_nr
INNER JOIN mitarbeiter m
ON m.ho_nr = h.ho_nr
INNER JOIN fachbereich f
ON f.fb_nr = m.fb_nr
AND f.fb_name = 'Informatik'
INNER JOIN lehrveranstaltung l
ON l.fb_nr = f.nb_nr
INNER JOIN professor p
ON p.pers_nr = m.pers_nr
INNER JOIN prof_haelt_lv pl
ON pl.pers_nr = p.pers_nr
AND pl.lv_nr = l.lv_nr
ORDER BY 2,
3 DESC;
Also, these section on your SQL, this has no connection to any table in your SQL
inner join fachbereich f on f.fb_name = 'Informatik'
-- only the 'informatik' events
you forgot the alias for prof_haelt_lv
inner join prof_haelt_lv on l.lv_nr = pl.lv_nr
-- make sure 'lehrveranstaltung' is from a professor
I have ran into a snag with my Linq-to-Sql.
I have a sql query that runs the way I want and usually I use Linqer to convert to Linq to see the general idea. But this time my SQL query seems to advanced for Linqer. :/
I think the problem is the INNER JOINS that are nested in the LEFT OUTER JOIN. Unfortunately I have never ran into this before and don't know how to solve it using Linq.
My SQL query looks like this:
SELECT c.[Company], c.[Name_First], c.[Name_Last], ort.[IDOriginatorRoleType],
ort.[RoleType] AS [OriginatorRoleType], o.[IDOriginator], o.[IDWork],
o.[IDContact], m.[IDMedia], m.[IDWork], m.[FileName], m.[FileNameOnDisk],
m.[DateAdded], w.[IDWork] AS [IDWork2], w.[ArticleNumber], w.[Title],
w.[FrontPageLow], w.[FrontPageLowOnDisk], w.[FrontPageHigh],
w.[FrontPageHighOnDisk]
FROM [dbo].[tblSubscriptionsWorks] AS sw
INNER JOIN [dbo].[tblWorks] AS w ON sw.[IDWork] = w.[IDWork]
LEFT OUTER JOIN [dbo].[tblMedias] AS m ON m.[IDWork] = w.[IDWork]
LEFT OUTER JOIN ([dbo].[tblOriginators] AS o
INNER JOIN [dbo].[tblOriginatorRoles] AS ors ON
o.[IDOriginatorRole] = ors.[IDOriginatorRole]
INNER JOIN [dbo].[tblOriginatorRoleTypes] AS ort ON
ors.[IDOriginatorRoleType] = ort.[IDOriginatorRoleType]
INNER JOIN [dbo].[tblContacts] AS c ON
o.[IDContact] = c.[IDContact]) ON
(o.[IDWork] = w.[IDWork]) AND (ort.[IDOriginatorRoleType] = 1)
WHERE sw.[IDWork_Subscription] = 9942
The left outer join is not a problem what I can see. You just have to divide the statement
LEFT OUTER JOIN ([dbo].[tblOriginators] AS o
INNER JOIN [dbo].[tblOriginatorRoles] AS ors ON
o.[IDOriginatorRole] = ors.[IDOriginatorRole]
INNER JOIN [dbo].[tblOriginatorRoleTypes] AS ort ON
ors.[IDOriginatorRoleType] = ort.[IDOriginatorRoleType]
INNER JOIN [dbo].[tblContacts] AS c ON
o.[IDContact] = c.[IDContact]) ON
(o.[IDWork] = w.[IDWork]) AND (ort.[IDOriginatorRoleType] = 1)
into another IQueryable list. In the example the variable db is the datacontext. Here is a suggestion to a solution:
//selects all the columns that is just in the select from the left join
var leftJoin=
(
from o in db.tblOriginators
join ors in db.tblOriginatorRoles
on o.IDOriginatorRole equals ors.IDOriginatorRole
join ort in db.tblOriginatorRoleTypes
on ors.IDOriginatorRoleType equals ort.IDOriginatorRoleType
join c in db.tblContacts
on o.IDContact equals c.IDContact
where ort.IDOriginatorRoleType==1
select new
{
o.IDWork,
c.Company,
c.Name_First,
c.Name_Last,
ort.IDOriginatorRoleType,
ort.RoleType,
o.IDOriginator,
o.IDContact
}
);
var output=(
from sw in db.tblSubscriptionsWorks
join w in db.tblWorks
on sw.IDWork equals w.IDWork
from m in db.tblMedias
.Where(x=>x.IDWork==w.IDWork).DefaultIfEmpty()
//Left join with the IQueryable list
from org in leftJoin
.Where(x =>x.IDWork==w.IDWork).DefaultIfEmpty()
where
sw.IDWork_Subscription == 9942
select new
{
org.Company,
org.Name_First,
org.Name_Last,
org.IDOriginatorRoleType,
OriginatorRoleType=org.RoleType,
org.IDOriginator,
org.IDWork,
m.IDMedia,
m.IDWork,
m.FileName,
m.FileNameOnDisk,
w.FrontPageLow,
w.FrontPageLowOnDisk,
w.FrontPageHigh,
w.FrontPageHighOnDisk
}
);
I have a SQL Server query that I need to convert to MySQL. I've never used SQL Server/T-SQL before, so I have no experience with FOR XML PATH. There's surprisingly little documentation on this sort of thing. If I remove the FOR XML PATH statement, MySQL returns the error "Operand should contain at least 1 column(s)."
It seems like the nested SELECT statements return strings containing raw XML data, but I don't have the original SQL Server database available to test that theory. I could emulate this effect easily if I knew the return schema.
The original query is below:
SELECT
har_autos.*, har_automodels.Model, har_automodels.MakeID, har_automakes.Make, har_autotypes.AutoType,
(SELECT har_notes.*, har_notelinks.Value
FROM har_notes
JOIN har_notelinks on (har_notes.ID = har_notelinks.NoteID)
WHERE har_autos.ID = har_notelinks.AutoID AND har_notes.NoteTypeID = 1)
AS 'UserNotes',
(SELECT har_notes.*, har_notelinks.Value
FROM har_notes
JOIN har_notelinks on (har_notes.ID = har_notelinks.NoteID)
WHERE har_autos.ID = har_notelinks.AutoID AND har_notes.NoteTypeID = 2)
AS 'EngineeringNotes'
FROM har_autos
LEFT JOIN har_automodels ON (har_autos.ModelID = har_automodels.ID)
LEFT JOIN har_automakes ON (har_automodels.MakeID = har_automakes.ID)
LEFT JOIN har_autotypes ON (har_autos.AutoTypeID = har_autotypes.ID)
UPDATE:
I rebuilt the query in its entirety and it now returns "Not unique table/alias: 'har_automakes'."
SELECT
har_autos.*,
har_automodels.Model,
har_automodels.MakeID,
har_automakes.Make,
har_autotypes.AutoType,
(SELECT
har_notes.ID,
har_notes.NoteTypeID,
har_notes.Text001,
har_notelinks.Value,
har_notelinks.AutoID,
har_autos.ID
FROM
har_notes
INNER JOIN har_notelinks ON (har_notes.ID = har_notelinks.NoteID),
har_autos
WHERE har_autos.ID = har_notelinks.AutoID AND har_notes.NoteTypeID = 1)
AS UserNotes,
(SELECT
har_notes.ID,
har_notes.NoteTypeID,
har_notes.Text001,
har_notelinks.Value,
har_notelinks.AutoID,
har_autos.ID
FROM
har_notes
INNER JOIN har_notelinks ON (har_notes.ID = har_notelinks.NoteID), har_autos
WHERE har_autos.ID = har_notelinks.AutoID AND har_notes.NoteTypeID = 2)
AS EngineeringNotes
FROM
har_autos
LEFT OUTER JOIN har_automodels ON (har_autos.ModelID = har_automodels.ID)
LEFT OUTER JOIN har_autotypes ON (har_autos.AutoTypeID = har_autotypes.ID),
har_automakes
LEFT OUTER JOIN har_automakes ON (har_automakes.MakeID = har_automakes.ID)
WHERE
ID = 1
This is the original T-SQL query (really sorry about all of these):
SELECT a.*, mo.Model, mo.MakeID, ma.Make, at.AutoType,
(SELECT n.*, nl.Value
FROM dbo.Notes n
JOIN dbo.NoteLinks nl on (n.ID = nl.NoteID)
WHERE a.ID = nl.AutoID AND n.NoteTypeID = 1
FOR XML PATH('Note'), TYPE
) AS 'UserNotes',
(SELECT n.*, nl.Value
FROM dbo.Notes n
JOIN dbo.NoteLinks nl on (n.ID = nl.NoteID)
WHERE a.ID = nl.AutoID AND n.NoteTypeID = 2
FOR XML PATH('Note'), TYPE
) AS 'EngineeringNotes'
FROM dbo.Autos a
LEFT JOIN dbo.AutoModels mo ON (a.ModelID = mo.ID)
LEFT JOIN dbo.AutoMakes ma ON (mo.MakeID = ma.ID)
LEFT JOIN dbo.AutoTypes at ON (a.AutoTypeID = at.ID)
