I was wondering if it's possible to change this raw SQL into CodeIgniter's Active Record Style?
$SQL = "SELECT DISTINCT c.ID, c.Title, c.VersionInfo, GROUP_CONCAT(DISTINCT i.FullName
ORDER BY cma.Ranking SEPARATOR ', ') AS Artists
FROM carriermodifications cm INNER JOIN carriers c ON cm.CarrierID=c.ID
LEFT JOIN carriermainartists cma ON cma.CarrierID=c.ID
LEFT JOIN identities i ON cma.IdentityID=i.ID
INNER JOIN carriermainartists scma ON scma.CarrierID=c.ID
INNER JOIN identities si ON scma.IdentityID=si.ID
WHERE cm.DataSourceID IN (16, 17) AND c.Verified=1 AND c.Hidden = 0 AND ((c.Filter & 1)=1)
AND (si.Nationality=2 OR c.Concept=4)
GROUP BY c.ID ORDER BY cm.ModificationDate DESC LIMIT 27";
Thanks a lot in advance

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)

I'm new to Oracle SQL, I'm being asked to do some scenarios to learn the different expressions and so on.
I'm currently working on this statement but I keep having trouble with syntax and trying to get my expressions in the correct place.
If you don't mind taking a look at what I'm doing wrong and helping me learn the correct syntax I'd appreciate it a lot.
I have to find everything in the Sale, SaleDetail, OrderStatus, Warehouse, User and StockDetail tables.
The fields I need to find are saleno, serialstart, serialend, the product description (label field), sale status (saleid (I think)), WarehouseName (WH.NAME)
Here below is the code I've written so far.
SELECT
S.SALENO,
SD.SERIALSTART,
SD.SERIALEND,
SDT.LABEL,
USR.USERNAME,
WH.NAME
FROM
ITR_SALE,
ITR_SALEDETAIL,
ITR_ORDER,
ITR_WAREHOUSE,
ITR_USER,
ITR_STOCKDETAIL
JOIN ITR_SALE S
JOIN ITR_SALEDETAIL SD ON S.ID = SD.SALENO
JOIN ITR_WAREHOUSE WH ON SD.ID = WH.NAME
JOIN ITR_ORDER ODR ON WH.ID = ODR.STATUSID
JOIN ITR_USER USR ON ODR.ID = USR.USERNAME
JOIN ITR_STOCKDETAIL ON USR.ID = SDT.LABEL
WHERE S.LASTSTATUSCHANGETIME
BETWEEN ('2016-01-01 00:00:00' AND '2016-12-31 23:59:59')
AND STATUSID = ('COMPLETED');
Below follows the error message
ORA-00905: missing keyword
00905. 00000 - "missing keyword"
*Cause:
*Action:
Error at Line: 21 Column: 1
EDIT:
Finished code below, changed a few expressions and conditions.
SELECT
S.SALENO,
SD.SERIALSTART,
SD.SERIALEND,
SDA.LABEL,
USR.USERNAME,
WH.NAME
FROM
ITR_SALE S
INNER JOIN
ITR_SALEDETAIL SD ON S.ID = SD.SALEID
INNER JOIN
ITR_ORDERSTATUS ODS ON SD.ID = ODS.ID
INNER JOIN
ITR_WAREHOUSE WH ON ODS.ID = WH.NAME
INNER JOIN
ITR_USER USR ON WH.ID = USR.USERNAME
INNER JOIN
ITR_STOCKDETAIL SDA ON USR.ID = SDA.LABEL
WHERE 'DATE' BETWEEN '2016-01-01' AND '2016-12-31'
AND S.STATUSID = '4';`
Use proper join syntax. Edit. Need to remove parenthesis from last line or user IN clause.
SELECT
S.SALENO,
SD.SERIALSTART,
SD.SERIALEND,
SDT.LABEL,
USR.USERNAME,
WH.NAME
FROM
ITR_SALE S INNER JOIN ITR_SALEDETAIL SD ON S.ID = SD.SALENO
INNER JOIN ITR_SALEDETAIL SD ON S.ID = SD.SALENO
INNER JOIN ITR_WAREHOUSE WH ON SD.ID = WH.NAME
INNER JOIN ITR_ORDER ODR ON WH.ID = ODR.STATUSID
INNER JOIN ITR_USER USR ON ODR.ID = USR.USERNAME
INNER JOIN ITR_STOCKDETAIL STD ON USR.ID = SDT.LABEL

AND STATUSID = 'COMPLETED';
The below code is written to get the all the parent and child relationship and want to understand why the And is not filtering the records but where does.
e.g-
select
s.name,
s.status,
s.start_date_active,
s.end_date_active,
s.salesrep_number,
p.name Parent_name,
p.status Parent_status,
p.start_date_active Parent_start_date_active,
p.end_date_active Parent_end_date_active,
FROM XXX_XX_SALESREPS s
left outer join XXX_XX_SALESREPS p
on s.attribute1 = p.salesrep_id
**and s.attribute1 = '100003916'**
this above query give all the rows from table s and do not filter it on '100003916' . But when i used ..
select
s.name,
s.status,
s.start_date_active,
s.end_date_active,
s.salesrep_number,
p.name Parent_name,
p.status Parent_status,
p.start_date_active Parent_start_date_active,
p.end_date_active Parent_end_date_active,
FROM XXX_XX_SALESREPS s
left outer join XXX_XX_SALESREPS p
on s.attribute1 = p.salesrep_id
**where s.attribute1 = '100003916'**
this query gives me just filter record. Why can anyone please answer it. Thanks in advance.
In your first case and s.attribute1 = '100003916' is part of your join criteria - and since it is left outer join it wont serve as a filter.
I have this SQL query and I want to use the same in Linq. I am confused as to how they use the group join alias in the main query?
SELECT '1st' AS POSITION , user as USR1, actiondate as ad1 , user2 as USR2, actiondate2 as ad2 ,user3 as USR3, actiondate3 as ad3, First as Co, * FROM APPLICATIONS A INNER JOIN
( SELECT MAX(ROW) AS MAXDATE ,APPLICATIONNO FROM FIRSTM
GROUP BY APPLICATIONNO) SULA1
ON A.APPLICATIONNO=SULA1.APPLICATIONNO
INNER JOIN FIRSTM FSTATUS
ON SULA1.APPLICATIONNO=FSTATUS.APPLICATIONNO AND
SULA1.MaxDate = FSTATUS.ROW
INNER JOIN APPLICATIONAPPLICANTS ON A.APPLICATIONNO
=APPLICATIONAPPLICANTS.APPLICATIONNO
Dim ds = From a In db.Model
Join b In db.1 On a.id Equals b.ID
Join c In db.2 On a.id Equals c.ID
Join d In db.3 On a.id Equals d.ID
Join f In db.4 On a.id Equals f.ID
Select a.id, a.Ref, a.Type, a.etc
Above is my linq query. At the moment I am only getting the first row from the db returned when there are currently 60 rows. Please can you tell me where I am going wrong and how to select all records.
Thanks in advance!
UPDATE:
When I take out all the joins like so:
Dim ds = From a In db.1, b In db.2, c In db.3, d In db.4, f In db.5
Select a.id, a.Ref, a.type, b.etc, c.etc, d.etc
I get a system.outofmemory exception!
You're only going to get a row produced when all of the joins match - in other words, when there's a row from Model with an AP, an Option, a Talk and an Invoice. My guess is that there's only one of those.
LINQ does an inner join by default. If you're looking for a left outer join (i.e. where a particular row may not have an Invoice, or a Talk etc) then you need to use a group join, usually in conjunction with DefaultIfEmpty.
I'm not particularly hot on VB syntax, but this article looks like it's what you're after.
