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.

this solved the problem
I have this query where I am trying to introduce a non-static value into PERCENTILE_CONT:
SELECT perf2.REVIEW_PERIOD
, PERCENTILE_CONT(goalsASP.GOAL*.01) WITHIN GROUP (ORDER BY AVG_AMT ASC) ast75
FROM repDB.TBL_PERFORMANCE perf2 JOIN
pz.CATEGORY C on perf2.DEPTCAT = C.id JOIN
repDB.TBL_GOALS_MATRIX goalsASP ON C.NAME = goalsASP.DIMENSION_Y
and perf2.REVIEW_PERIOD = goalsASP.SNAP_NAME
and goalsASP.DIMENSION_X = 'asp'
GROUP BY perf2.REVIEW_PERIOD
The error thrown is:
ORA-30497: Argument should be a constant or a function of expressions in GROUP BY.
30497. 00000 - "Argument should be a constant or a function of expressions in GROUP BY."
This is in a view, it was working fine when goalsASP.GOAL*.01 was .75 and I have a stored procedure where feeding a column as an argument works just fine so I'm kind of at a loss for what I'm doing wrong here.
Got it. It's not so much a problem of Percentile_Cont, it's a problem of correct grouping.
To troubleshoot I isolated goalsASP.GOAL
SELECT perf2.REVIEW_PERIOD
, goalsASP.GOAL
FROM repDB.TBL_PERFORMANCE perf2 JOIN
pz.CATEGORY C on perf2.DEPTCAT = C.id JOIN
repDB.TBL_GOALS_MATRIX goalsASP ON C.NAME = goalsASP.DIMENSION_Y
and perf2.REVIEW_PERIOD = goalsASP.SNAP_NAME
and goalsASP.DIMENSION_X = 'asp'
GROUP BY perf2.REVIEW_PERIOD
Then it became obvious that I needed to also group by goalsASP.GOAL.
So, then, the answer is:
SELECT perf2.REVIEW_PERIOD
, PERCENTILE_CONT(goalsASP.GOAL*.01) WITHIN GROUP (ORDER BY AVG_AMT ASC) ast75
FROM repDB.TBL_PERFORMANCE perf2 JOIN
pz.CATEGORY C on perf2.DEPTCAT = C.id JOIN
repDB.TBL_GOALS_MATRIX goalsASP ON C.NAME = goalsASP.DIMENSION_Y
and perf2.REVIEW_PERIOD = goalsASP.SNAP_NAME
and goalsASP.DIMENSION_X = 'asp'
GROUP BY perf2.REVIEW_PERIOD,
goalsASP.GOAL
Kind of embarrassing that I didn't see that before, but tired eyes miss this stuff.
I'm migrating a client's software database from Oracle to PostgreSQL, and I have some trouble understanding a query, what it does, and consequently how to migrate it.
The query is:
SELECT *
FROM TBL1, TBL2, TBL3, TBL4
WHERE TBL3.Project_ID = TBL1.Project_ID
AND TBL2.Type_ID = TBL1.Type_ID
AND TBL4.PROPERTY_NAME(+)='Id'
AND TBL4.Entity_ID(+)=TBL1.Entity_ID
And the part I don't get, is the outer join (+) on 'Id'.
A join on a table, OK, but on a string? I've no idea of what it does.
Do someone has an idea?
Thanks.
TBL4.PROPERTY_NAME(+)='Id' means when the line was inner joined, then the value has to be 'Id', but when the line was outer joined, the condition is evaluated as true
however you should rewrite the statement to the standard as:
SELECT *
FROM TBL1
JOIN TBL2 ON TBL2.Type_ID = TBL1.Type_ID
JOIN TBL3 ON TBL3.Project_ID = TBL1.Project_ID
LEFT JOIN TBL4 ON TBL4.Entity_ID=TBL1.Entity_ID AND TBL4.PROPERTY_NAME='Id'
This is the equivalent of the following query using ANSI join syntax:
SELECT *
FROM TBL1 t1
INNER JOIN TBL2 t2 ON (t1.Type_ID = t2.Type_ID)
INNER JOIN TBL3 t3 ON (t3.Project_ID = t1.Project_ID)
LEFT JOIN TBL4 t4 ON (t4.Entity_ID = t1.Entity_ID AND t4.PROPERTY_NAME = 'Id')
You're not joining to a string, merely specifying a join condition that's based on one.
Im trying to convert a SQL join to LINQ. I need some help in getting the nested join working in LINQ.
This is my SQL query, Ive cut it short just to show the nested join in SQL:
select distinct
txtTaskStatus as TaskStatusDescription,
txtempfirstname+ ' ' + txtemplastname as RaisedByEmployeeName,
txtTaskPriorityDescription as TaskPriorityDescription,
dtmtaskcreated as itemDateTime,
dbo.tblTask.lngtaskid as TaskID,
dbo.tblTask.dtmtaskcreated as CreatedDateTime,
convert(varchar(512), dbo.tblTask.txttaskdescription) as ProblemStatement,
dbo.tblTask.lngtaskmessageid,
dbo.tblMessage.lngmessageid as MessageID,
case when isnull(dbo.tblMessage.txtmessagesubject,'') <> '' then txtmessagesubject else left(txtmessagedescription,50) end as MessageSubject,
dbo.tblMessage.txtmessagedescription as MessageDescription,
case when dbo.tblMessage.dtmmessagecreated is not null then dbo.tblMessage.dtmmessagecreated else CAST(FLOOR(CAST(dtmtaskcreated AS DECIMAL(12, 5))) AS DATETIME) end as MessageCreatedDateTime
FROM
dbo.tblAction RIGHT OUTER JOIN dbo.tblTask ON dbo.tblAction.lngactiontaskid = dbo.tblTask.lngtaskid
LEFT OUTER JOIN dbo.tblMessage ON dbo.tblTask.lngtaskmessageid = dbo.tblMessage.lngmessageid
LEFT OUTER JOIN dbo.tblTaskCommentRecipient
RIGHT OUTER JOIN dbo.tblTaskComment ON dbo.tblTaskCommentRecipient.lngTaskCommentID = dbo.tblTaskComment.lngTaskCommentID
ON dbo.tblTask.lngtaskid = dbo.tblTaskComment.lngTaskCommentTaskId
A more seasoned SQL programmer wouldn't join that way. They'd use strictly left joins for clarity (as there is a strictly left joining solution available).
I've unraveled these joins to produce a hierarchy:
Task
Action
Message
TaskComment
TaskCommentRecipient
With associations created in the linq to sql designer, you can reach these levels of the hierarchy:
//note: these aren't outer joins
from t in db.Tasks
let actions = t.Actions
let message = t.Messages
let comments = t.TaskComments
from c in comments
let recipients = c.TaskCommentRecipients
DefaultIfEmpty produces a default element when the collection is empty. Since these are database rows, a default element is a null row. That is the behavior of left join.
query =
(
from t in db.Tasks
from a in t.Actions.DefaultIfEmpty()
from m in t.Messages.DefaultIfEmpty()
from c in t.Comments.DefaultIfEmpty()
from r in c.Recipients.DefaultIfEmpty()
select new Result()
{
TaskStatus = ???
...
}
).Distinct();
Aside: calling Distinct after a bunch of joins is a crutch. #1 See if you can do without it. #2 If not, see if you can eliminate any bad data that causes you to have to call it. #3 If not, call Distinct in a smaller scope than the whole query.
Hope this helps.
SELECT [t0].[OrderID], [t0].[CustomerID], [t0].[EmployeeID], [t0].[OrderDate], [t0].[RequiredDate], [t0].[ShippedDate], [t0].[ShipVia], [t0].[Freight], [t0].[ShipName], [t0].[ShipAddress], [t0].[ShipCity], [t0].[ShipRegion], [t0].[ShipPostalCode], [t0].[ShipCountry]

LEFT OUTER JOIN ([Order Details] AS [t1]
INNER JOIN [Products] AS [t2] ON [t1].[ProductID] = [t2].[ProductID]) ON [t0].[OrderID] = [t1].[OrderID]
can be write as
from o in Orders
join od in (
from od in OrderDetails join p in Products on od.ProductID equals p.ProductID select od)
on o.OrderID equals od.OrderID into ood from od in ood.DefaultIfEmpty()
select o
I have a query which have multiple conditions on on clause
SELECT *
FROM
CATALOGITEM with (nolock) INNER JOIN CATALOG with (nolock) ON
CATALOGITEM.catalog_id = CATALOG.catalog_id and not(catalog.catalog_id = 21) AND NOT(catalog.catalog_id = 20)
INNER JOIN PRODUCT with (nolock) ON
CATALOGITEM.s_num = PRODUCT .s_num
LEFT OUTER JOIN PRODUCT_DETAIL with (nolock) ON
PRODUCT_DETAIL.s_num = PRODUCT.s_num
WHERE
(
CATALOGITEM.publish_code = 'upd' OR
CATALOG_ITEM.publish_code = 'ins' OR
PRODUCT.publish_code = 'upd' OR
PRODUCT.publish_code = 'ins'
)
and
(CATALOG.unit_id = bu.unit_id)
How to write this in LINQ.
Please advice.
Assume you're missing a join to PRODUCT table?
Anyway, this should get you started.
var query = (from ci in db.catalogitem
join c in db.catalog on ci.catalog_id equals c.catalog_id
join p in db.products on ci.s_num equals p.s_num
join pd in db.productdetail on p.s_num equals pd.s_num into tempprods
from prods in tempprods.DefaultIfEmpty()
where !(c.catalog_id.Contains(21, 20))
&& (ci.publish_code.Contains('upd','ins')) ||
(p.publish_code.Contains('upd','ins'))
select ci)
If you want to preserve the (NOLOCK) hints, I have blogged a handy solution using extension methods in C#. Note that this is the same as adding nolock hints to every table in the query.
