I have this sql query which works fine, how can i write this in eloquent( eager loading) using relationships, not joins.
SELECT ads.id,ads.name,u.name,country_translates.name,city_translate.name,category_translates.name
FROM ads
INNER JOIN users u ON ads.user_id = u.id
INNER JOIN cities ON ads.city_id = cities.id
INNER JOIN country_translates ON cities.country_id = country_translates.country_id
INNER JOIN city_translate ON ads.city_id = city_translate.city_id
INNER JOIN category_translates ON ads.category_id = category_translates.category_id
WHERE country_translates.language_id = 2 AND city_translate.language_id = 2 AND category_translates.language_id = 2

I need to convert a SQL query into LINQ, either to Query Syntax or Method Syntax.
SELECT
IA.ItemId,
IVT.ItemName,
C.DeliveryMethod,
SUM(OD.Quantity) AS Qty
FROM OrderHeader OH
INNER JOIN OrderDetail OD ON OH.OrderId = OD.OrderId
LEFT JOIN Customer C ON OH.CustomerId = C.Id
LEFT JOIN ItemAvailability IA ON OD.ItemId = IA.RecId
INNER JOIN Inventory IVT ON IA.ItemId = IVT.ItemId
WHERE OH.DeliveryDate = '02/03/2023'
AND OH.OrderType = 'Web'
GROUP BY IA.ItemId, Ivt.ItemName, C.DlvMode
ORDER BY IA.ItemId
I've spent a long time Googling and YouTubing, but everyone provides examples of either just Inner Joins, Group Joins, or Left Joins. No one gave example of having both Inner Joins and Left Joins in the same query.
I know the syntax for a simple inner join like this:
SQL
SELECT OH.OrderId, OD.ItemId, OD.Quantity
FROM OrderHeader OH
INNER JOIN OrderDetail OD ON OH.OrderId = OD.OrderId
ORDER BY OD.ItemId
LINQ
from oh in OrderHeader
join od in OrderDetail on oh.OrderId equals od.OrderId
orderby ordt.IItemId
select new {
OrderId = oh.OrderId,
ItemId = od.ItemId,
Quantity = od.Quantity
}
And I know the LINQ syntax for left join also. But I am having trouble to figure out how to have both inner and left joins in one LINQ query.
I hope someone here can help, please.
Just combine join techniques together
var deliveryDate = ...;
var query =
from oh in OrderHeader
join od in OrderDetail on oh.OrderId equals od.OrderId
join c in Customer ON oh.CustomerId equals c.Id into cj
from c in cj.DefaultIfEmpty()
join ia in ItemAvailability on od.ItemId equals ia.RecId into iaj
from ia in iaj.DefaultIfEmpty()
join ivt in Inventory on ia.ItemId equals ivt.ItemId
where oh.DeliveryDate == deliveryDate && oh.OrderType == "Web"
group od by new { ia.ItemId, ivt.ItemName, c.DlvMode, c.DeliveryMethod } into g
select new
{
g.Key.ItemId,
g.Key.DeliveryMethod,
Qty = g.Sum(x => x.Quantity)
} into s
orderby s.ItemId
select s;
I have been stuck on this one for a few days, in part due to the depths of the query. You might as well have the true query in all its current glory too:
$submissions = Submission::with([
'authGroupPriority',
'authGroupPriority.groupData',
'claimData',
'claimData.claimUser',
'claimData.claimForm',
'claimData.claimStatus',
'authGroupPriority.formData',// => function($query){$query->where('forms.id', 1);},
'authGroupPriority.users' => function($query){
$query->where('users.id', Auth::id());
}])->whereHas('authGroupPriority.users', function($query){
$query->where('users.id', Auth::id());
})/*->whereHas('authGroupPriority.formData', function($query){$query->where('forms.id', 1);})*/
->get();
Right so most of the relationships are one to one or one to many relationships here and this is the desired outcome:
Submission
WHERE current user is in list of authGroupPriority.users
WHERE submission.level EQUALS claimData.claimForm.authGroups.level
Thats the basics anyway. I am happy with setting up whereHas and with functions to be the same, just can't work out how to pass in submission level in a whereHas (or with) on the deep nested relationship. Any ideas or am I overcomplicating this somehow?
EDIT:
After spending the afternoon on this query I finally got the one that works (in SQL)
SELECT * from submissions
INNER JOIN(SELECT users.uid, forms.id, forms.name, claims.id AS claimsId FROM claims
INNER JOIN submissions ON submissions.claim = claims.id
INNER JOIN forms ON forms.forms.id = claims.form
INNER JOIN users ON claims.user = users.id) F ON F.claimsId = submissions.claim
INNER JOIN (SELECT auth_group_members.priority FROM auth_group_members
INNER JOIN groupmembership ON auth_group_members.authGroup = groupmembership.groupID
WHERE groupmembership.userID = 1) AG ON AG.priority = submissions.chainPosition
GROUP BY submissions.claim;
Its not pretty but it works. The question is, is this Laravelifiable (new word I think I'm going to claim)? (withs and wherehas's)
EDIT 2:
The SQL above isn't right but its almost right. Just got one more filter to add and thats the submission level = the auth groups level
EDIT 3:
SELECT * FROM submissions
INNER JOIN (SELECT users.uid, forms.id, forms.name, claims.id as claimsId FROM claims
INNER JOIN submissions ON submissions.claim = claims.id
INNER JOIN forms ON forms.forms.id = claims.form
INNER JOIN users ON claims.user = users.id) F ON F.claimsId = submissions.claim
INNER JOIN (SELECT auth_group_members.form, auth_group_members.priority FROM auth_group_members
INNER JOIN groupmembership ON auth_group_members.authGroup = groupmembership.groupID
WHERE groupmembership.userID = 1) AG ON AG.priority = submissions.chainPosition AND AG.form = F.id
GROUP BY submissions.claim
as tittle says i need to improve this query that i have made in ms access, the tables are from a linked DB. i can't index them. i need help to understand where it is taking so long... is there any function like
EXPLAIN to access? do i need to put more columns in some sort of group by? what i need to do to improve the speed of this (the group by of first select has 4M rows but after grouped only has 321k and it takes 20min to run when laptop doesn't crashes)

this solved the problem
I'm trying to build a linq query based on this:
select
SERVICE_REQUEST_CR.SRCR_FK_SR, SERVICE_REQUEST.SR_TX_NAME,
AC_USER.USER_TX_NAME, SERVICE_REQUEST_CR.SRCR_DT_CREATED,
SERVICE_REQUEST_CR_STATUS.SRCRST_TX_DESCRIPTION,
COUNT(SERVICE_REQUEST_PROGRAM.SRPG_FK_SR_ID) as Activities
from
SERVICE_REQUEST_CR
inner join
AC_USER on AC_USER.USER_ID = SERVICE_REQUEST_CR.SRCR_FK_REQUESTOR
inner join
SERVICE_REQUEST_CR_STATUS on SERVICE_REQUEST_CR_STATUS.SRCRST_ID = SERVICE_REQUEST_CR.SRCR_FK_CR_STATUS
inner join
SERVICE_REQUEST on SERVICE_REQUEST.SR_ID = SERVICE_REQUEST_CR.SRCR_FK_SR
inner join
SERVICE_REQUEST_PROGRAM on SERVICE_REQUEST_PROGRAM.SRPG_FK_SR_ID = SERVICE_REQUEST_CR.SRCR_FK_SR
group by
SERVICE_REQUEST_CR.SRCR_FK_SR, SERVICE_REQUEST.SR_TX_NAME,
AC_USER.USER_TX_NAME, SERVICE_REQUEST_CR.SRCR_DT_CREATED,
SERVICE_REQUEST_CR_STATUS.SRCRST_TX_DESCRIPTION,
SERVICE_REQUEST_PROGRAM.SRPG_FK_SR_ID
This is as far as I could come up with:
Dim x = From cr In db.SERVICE_REQUEST_CR
Join usr In db.AC_USER On usr.USER_ID Equals cr.SRCR_FK_REQUESTOR
Join crSt In db.SERVICE_REQUEST_CR_STATUS On crSt.SRCRST_ID Equals cr.SRCR_FK_CR_STATUS
Join sr In db.SERVICE_REQUEST On sr.SR_ID Equals cr.SRCR_FK_SR
Join srProg In db.SERVICE_REQUEST_PROGRAM On srProg.SRPG_FK_SR_ID Equals cr.SRCR_FK_SR
Could anyone give me a help with this? It's the grouping that gets confusing so I just put the joins and the query to keep it simple.
Thanks,
Something like this, but I am not sure about Basic syntax:
Dim x = From cr In db.SERVICE_REQUEST_CR
Join usr In db.AC_USER On usr.USER_ID Equals cr.SRCR_FK_REQUESTOR
Join crSt In db.SERVICE_REQUEST_CR_STATUS On crSt.SRCRST_ID Equals cr.SRCR_FK_CR_STATUS
Join sr In db.SERVICE_REQUEST On sr.SR_ID Equals cr.SRCR_FK_SR
Join srProg In db.SERVICE_REQUEST_PROGRAM On srProg.SRPG_FK_SR_ID Equals cr.SRCR_FK_SR
group new
{
cr.SRCR_FK_SR,
sr.SR_TX_NAME,
usr.USER_TX_NAME,
cr.SRCR_DT_CREATED,
crSt.SRCRST_TX_DESCRIPTION,
srProg.SRPG_FK_SR_ID
}
by new
{
cr.SRCR_FK_SR,
sr.SR_TX_NAME,
usr.USER_TX_NAME,
cr.SRCR_DT_CREATED,
crSt.SRCRST_TX_DESCRIPTION,
srProg.SRPG_FK_SR_ID
} into gr
select new

gr.Key.SRCR_FK_SR,
gr.Key.SR_TX_NAME,
