(Laravel 5.6)
I'm having issues executing DB::unprepared query in a laravel migration. The query is valid, as I can copy-paste it directly in my db management app. But within an unprepared query, nada. I'm not getting any errors whatsoever.
I've tried using DB::raw and a combination of the two, as seen in other posted questions, to no avail. Anybody spot any obvious errors that I'm missing? TIA.
DB::unprepared(
'Update protocols AS P
INNER JOIN (
SELECT auditable_id, updated_at
FROM logs
WHERE auditable_type = \'App\\Protocol\'
AND event = \'updated_status\'
AND new_values LIKE \'%pending irb specialist review%\'
OR
auditable_type = \'App\\Protocol\'
AND event = \'updated_status\'
AND new_values LIKE \'%pending faculty sponsor approval%\'
)
AS L ON L.auditable_id = P.id
SET P.submitted_on = L.updated_at
WHERE P.id = L.auditable_id'
);

I have currently a query with a bunch of filters, which makes sense to use the Criteria API, unfortunately I have this query that uses a Join which uses a string value instead of a relationship. This is an example of the query:
SELECT ua.id,
COALESCE(uf.status, f.status) AS status,
r.name,
ua.companyname,
ua.firstname,
ua.lastname,
ua.usergroup,
ua.email,
ua.country,
ua.continent
FROM useraccount ua
JOIN userrole ur on ua.id = ur.userid
JOIN role r on ur.roleid = r.id and r.eventgroupid = 1
JOIN feature f on f.name = 'Locked'
LEFT JOIN userfeature uf on uf.featureid = f.id AND uf.userid = ua.id;
As you can see the problem of the query is that I want to use COALESCE operation to get a UserFeature status if present, if not use the default status from the Feature table.
The feature table is just a simple one with id, name and the status, it is only related to UserFeature and UserFeature at the same time is related to the UserAccount.
As you might guess the CriteriaAPi doesn't allows a Join<> by a regular string value. I have tried to get my mind around to get how can I change the select statement to be more aligned with what CriteriaAPI offers, but I haven't found anything on this.
I'm using PostgreSQL and Hibernate 5.4.32 (by using the spring starter jpa)
I have a performance issue with the API. It is due to retrieving data from multiple tables like below
Example:
Users.Include(x => x.UsersAdditionInfo)
.Include(x => x.UserRoles)
.Include(x => x.Location)
Note: each of these tables contains nearly (1,50,000) records except location table.
I have used joins instead of .Include then also facing the same performance issues.
Example:
from ub in users
join ua in UserAdditionalInfo on ub.Id equals ua.UserId
join ur in UserRoles on ub.Id equals ur.UserId
join urs in userRoles on ur.RoleId equals urs.Id
join l in Location on ub.LocationId equals l.Id
into leftLocation
from location in leftLocation.DefaultIfEmpty()
Kindly suggest for better alternative ways to query in multiple tables
If your EDMX is probably configured, you don't have to join yourself.
Can't you just do
Users.Select(x=> new {
UserRoles = x.UserRoles,
UserAdditionInfo = x.UserAdditionInfo,
Location = x.Location })
and so on?
(I've fudged your schema a bit but hopefully you get my point)
Also, if this is common, you could also always create a view in SQL Server and add it in EDMX
At my job our main application was written long ago before n-tier was really a thing, ergo - it has tons and tons of business logic begin handled in stored procs and such.
So we have finally decided to bite the bullet and make it not suck so bad. I have been tasked with converting a 900+ line sql script to a .NET exe, which I am doing in C#/Linq. Problem is...for the last 5-6 years at another job, I had been doing Linq exclusively, so my SQL has gotten somewhat rusty, and some of thing I am converting I have never tried to do before in Linq, so I'm hitting some roadblocks.
Anyway, enough whining.
I'm having trouble with the following sql statement, I think due to the fact that he is joining on a temp table and a derived table. Here's the SQL:
insert into #processedBatchesPurgeList
select d.pricebatchdetailid
from pricebatchheader h (nolock)
join pricebatchstatus pbs (nolock) on h.pricebatchstatusid = pbs.pricebatchstatusid
join pricebatchdetail d (nolock) on h.pricebatchheaderid = d.pricebatchheaderid
join
( -- Grab most recent REG.
select
item_key
,store_no
,pricebatchdetailid = max(pricebatchdetailid)
from pricebatchdetail _pbd (nolock)
join pricechgtype pct (nolock) on _pbd.pricechgtypeid = pct.pricechgtypeid
where
lower(rtrim(ltrim(pct.pricechgtypedesc))) = 'reg'
and expired = 0
group by item_key, store_no
) dreg
on d.item_key = dreg.item_key
and d.store_no = dreg.store_no
where
d.pricebatchdetailid < dreg.pricebatchdetailid -- Make sure PBD is not most recent REG.
and h.processeddate < #processedBatchesPurgeDateLimit
and lower(rtrim(ltrim(pbs.pricebatchstatusdesc))) = 'processed' -- Pushed/processed batches only.
So that's raising an overall question first: how to handle temp tables in Linq? This script uses about 10 of them. I currently have them as List. The problem is, if I try to .Join() on one in a query, I get the "Local sequence cannot be used in LINQ to SQL implementations of query operators except the Contains operator." error.
I was able to get the join to the derived table to work using 2 queries, just so a single one wouldn't get nightmarishly long:
var dreg = (from _pbd in db.PriceBatchDetails.Where(pbd => pbd.Expired == false && pbd.PriceChgType.PriceChgTypeDesc.ToLower().Trim() == "reg")
group _pbd by new { _pbd.Item_Key, _pbd.Store_No } into _pbds
select new
{
Item_Key = _pbds.Key.Item_Key,
Store_No = _pbds.Key.Store_No,
PriceBatchDetailID = _pbds.Max(pbdet => pbdet.PriceBatchDetailID)
});
var query = (from h in db.PriceBatchHeaders.Where(pbh => pbh.ProcessedDate < processedBatchesPurgeDateLimit)
join pbs in db.PriceBatchStatus on h.PriceBatchStatusID equals pbs.PriceBatchStatusID
join d in db.PriceBatchDetails on h.PriceBatchHeaderID equals d.PriceBatchHeaderID
join dr in dreg on new { d.Item_Key, d.Store_No } equals new { dr.Item_Key, dr.Store_No }
where d.PriceBatchDetailID < dr.PriceBatchDetailID
&& pbs.PriceBatchStatusDesc.ToLower().Trim() == "processed"
select d.PriceBatchDetailID);
So that query gives the expected results, which I am holding in a List, but then I need to join the results of that query to another one selected from the database, which is leading me back to the aforementioned "Local sequence cannot be used..." error.
That query is this:
insert into #pbhArchiveFullListSaved
select h.pricebatchheaderid
from pricebatchheader h (nolock)
join pricebatchdetail d (nolock)
on h.pricebatchheaderid = d.pricebatchheaderid
join #processedBatchesPurgeList dlist
on d.pricebatchdetailid = dlist.pricebatchdetailid -- PBH list is restricted to PBD purge list rows that have PBH references.
group by h.pricebatchheaderid
The join there on #processedBatchesPurgeList is the problem I am running into.
So uh...help? I have never written SQL like this, and certainly never tried to convert it to Linq.
As pointed out by the comments above, this is no longer being rewritten as Linq.
Was hoping to get a performance improvement along with achieving better SOX compliance, which was the whole reason for the rewrite in the first place.
I'm happy with just satisfying the SOX compliance issues.
Thanks, everyone.
I have two entities who are N:N - related with each other. With an example I'll show you what I mean :
I have a Session (ave_Session) and there we can put "Trainers"
(ave_trainer) on each Session
I'm tryting to get a list of al the
"Trainers" for a particular Session
They are related to each other in
N:N (relationship name : ave_ave_session_ave_trainer)
I work in VS2010 and with C# => I'm trying to get the data through LINQ
I recently just started with LINQ, so maybe you guys can help me out on this one. The following I've tried and i gave me an "AttributeFrom and AttributeTo must be either both specified or both ommited. You can not pass only one or the other. AttributeFrom: , AttributeTo: ave_trainerid"-error :
var formatteurs = (from f in ORGContext.CreateQuery<ave_trainer>()
join s in ORGContext.CreateQuery<ave_ave_session_ave_trainer>() on f.Id equals s.ave_trainerid.Value
join c in ORGContext.CreateQuery<ave_session>() on s.ave_sessionid.Value equals c.Id
where c.Id == item.Id
select f).ToList();
The item.id is the Id of the session. Thx in advance if you can help me out!
From the MSDN page:
// List the contacts in the Softball team marketing list.
System.Console.WriteLine("List all contacts in Softball Team:");
var members = from c in crm.contacts
join mlm in crm.listmembers on c.contactid equals mlm.entityid
join ml in crm.lists on mlm.listid equals ml.listid
where ml.listname == "Softball Team"
select c;
foreach (var c in members)
{
System.Console.WriteLine(c.fullname + " " + c.emailaddress1);
}
It seems a little backwards the way you have it written now (assuming I'm parsing it correctly).
What you'd normally do is put your 'starting thing' first and then go through the mapping to get to the ones you want. I don't have any CRM 2011 experience, so hopefully I didn't mess this up too much. :)
Also, I'm not a fan of single-character names, so I took the liberty of using longer names :)
var formatteurs = (
// first get the session we're interested in
from session in ORGContext.CreateQuery<ave_session>()
where session.Id == item.Id
// now get the mapping rows that are related to it
join mapping in ORGContext.CreateQuery<ave_ave_session_ave_trainer>()
on session.Id equals s.ave_sessionid.Value
// now get from the mapping rows to the actual trainers
join trainer in ORGContext.CreateQuery<ave_trainer>()
on mapping.ave_trainerid.Value equals trainer.Id
select trainer
).ToList();
I'm new to Doctrine but somewhat familiar with SQL. I have a very simple schema with Users and Challenges. Each Challenge has a "challenger id" and a "opponent id" which are foreign keys into the User table. I want to print a list of all challenges, with the output being the names from the User table. Here is my Doctrine query;
$q = Doctrine_Query::create()
->select('u1.name challenger, u2.name opponent')
->from('Challenge c')
->leftJoin('c.Challenger u1')
->leftJoin('c.Opponent u2');
The problem is that this only returns one row. I've used the getSqlQuery() command to look at the generated SQL which ends up being:
SELECT u.name AS u__0, u2.name AS u2__1 FROM challenge c
LEFT JOIN user u ON c.challenger_id = u.id
LEFT JOIN user u2 ON c.opponent_id = u2.id
When run in a 3rd party SQL client this query retrieves all of the rows as expected. Any idea how I can get all of the rows from Doctrine? I'm using $q->execute() which I understand should work for multiple rows.
Thanks.
For me it worked by chaning the hydration mode:
$result = $query->execute(array(), Doctrine_Core::HYDRATE_SCALAR);
Set result set then returns an array instead of objects.
I just ran into this issue and in my case the problem was that my query didn't select any field from the FROM table. Example:
$query = Doctrine_Query::create()
->select(
'ghl.id as id,
ghl.patbase_id as patbase_id,
ghl.publication_no as publication_no,
ghl.priority_no as priority_no
'
)
->from('GridHitListContents ghlc')
->leftJoin('ghlc.GridHitList ghl')
As you can see there is no selected field from the GridHitListContents table.
with a $query->count() I got 2000ish results, but with $query->fetchArray() only the first one.
When I added
$query = Doctrine_Query::create()
->select(
'ghlc.id,
ghl.id as id,
...
'
)
->from('GridHitListContents ghlc')
->leftJoin('ghlc.GridHitList ghl')
I got back all my results.
$query->fetchOne() work fine for me.
Use this $result = $q->execute(array(), Doctrine_Core::HYDRATE_ARRAY)
