I have the below Pivot and output. I would like to display the below.
Remove the parentheses around the columns?
Add indicator of X and Null in substitute of 1 and 0?
SQL:
SELECT DISTINCT
*
FROM (
SELECT D.ID, D.DI, A.ID
FROM A
LEFT JOIN AD ON A.ID = AD.ID
LEFT JOIN D ON AD.ID = D.ID
WHERE 1=1
AND A.ID = 890929
)
PIVOT
(
COUNT(ID)
FOR DI IN ( 'Low med','Soft','Regular','High Med','Other')
)
Query output:
ID 'Low med' 'Soft' 'Regular' 'High Med' 'Other'
1 1 1 0 0 1
Expected output:
ID LOW_MED SOFT REGULAR HIGH_MED OTHER
1 X X NULL NULL X
You can remove the single quotes (not parentheses, which are ()), by aliasing the pivoted expressions:
FOR DI IN ('Low med' as low_med, 'Soft' as soft, 'Regular' as regular,
'High Med' as high_med,'Other' as other)
You can then use those aliases for the second part, but adding case expressions to your main query:
SELECT id,
case when low_med = 1 then 'X' else null end as low_med,
case when soft = 1 then 'X' else null end as soft,
case when regular = 1 then 'X' else null end as regular,
case when high_med = 1 then 'X' else null end as high_med,
case when other = 1 then 'X' else null end as other
FROM (
SELECT D.ID, D.DI, A.ID
FROM A
LEFT JOIN AD ON A.ID = AD.ID
LEFT JOIN D ON AD.ID = D.ID
WHERE 1=1
AND A.ID = 890929
)
PIVOT
(
COUNT(ID)
FOR DI IN ('Low med' as low_med, 'Soft' as soft, 'Regular' as regular,
'High Med' as high_med,'Other' as other)

I've got to make it work on Oracle 8i [I know it's a REALLY old version, but I have no choice since it's not my DB]. I've built this query in order to get the data from Oracle 8i: [I've changed CASE WHEN for DECODE and removed all the ANSI JOINs]

The new query is definately not OK because it's taking forever to run. So what would be the correct form of the first query in order to get data from Oracle 8i?
UPDATE:
Result of the query:
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
01652. 00000 - "unable to extend temp segment by %s in tablespace %s"
*Cause: Failed to allocate an extent of the required number of blocks for
a temporary segment in the tablespace indicated.
*Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more
files to the tablespace indicated.
Thanks in advance!
I don't see this condition in your Oracle 8 version:
t9.BACPM_ID = t3.BACPM_ID
That could explain the performance problem.
This is my query:
SELECT count(oi.id) imgCnt, o.*,
IF(pricet=2,c.currency_value*o.attributes_36*o.price,
c.currency_value*o.price) AS pprice, od.title, oi.image,
MIN(oi.id), ( c.currency_value * o.price ) AS fprice,
ag.agent_name, DATE_FORMAT( o.date_added, '%d-%m-%Y') as dadded
FROM i_offers_12 o
LEFT JOIN i_agents ag ON o.agents_id = ag.id
LEFT JOIN i_currencies c ON o.currencies_id = c.id
LEFT JOIN i_offers_details od ON ( o.id = od.offers_id AND od.languages_id = 1 )
LEFT JOIN i_offers_images oi ON ( oi.offers_id = o.id AND oi.o_id = '12' )

AND actions_id = '1'
AND c.id = o.currencies_id
AND o.counties_id = '2'
AND o.cities_id = '3'
GROUP BY o.id
ORDER BY dadded
DESC
I want to sort after dadded(which is of type date) and offer_status(which is of type enum).
I want to display first, all of the elements which have offer_status = 'active' and sort by dadded and after that all of the elements which have offer_status = 'sold' and sort also by dadded. How can I do that? thx
The fields you want to sort on MUST be part of the select statement:
SELECT count(oi.id) imgCnt, o.*,
IF(pricet=2,c.currency_value*o.attributes_36*o.price,
c.currency_value*o.price) AS pprice, od.title, oi.image,
MIN(oi.id), ( c.currency_value * o.price ) AS fprice,
ag.agent_name, DATE_FORMAT( o.date_added, '%d-%m-%Y') as dadded ,
offer_status
FROM i_offers_12 o
LEFT JOIN i_agents ag ON o.agents_id = ag.id
LEFT JOIN i_currencies c ON o.currencies_id = c.id
LEFT JOIN i_offers_details od ON ( o.id = od.offers_id AND od.languages_id = 1 )
LEFT JOIN i_offers_images oi ON ( oi.offers_id = o.id AND oi.o_id = '12' )
WHERE ( o.offer_status='active' OR o.offer_status='sold')
AND actions_id = '1'
AND c.id = o.currencies_id
AND o.counties_id = '2'
AND o.cities_id = '3'
AND o.offer_status='active'
GROUP BY o.id
ORDER BY offer_status, dadded
DESC
Note that you normally should group by ALL non summarized fields (o.*,
IF(pricet=2,c.currency_value*o.attributes_36*o.price,
c.currency_value*o.price) AS pprice, od.title, oi.image, ( c.currency_value * o.price ) AS fprice,
ag.agent_name, DATE_FORMAT( o.date_added, '%d-%m-%Y') as dadded ,
offer_status)
MySQL is not enforcing it, but other DB like Oracle does.
You can use a comma, like
ORDER BY supplier_city DESC, supplier_state ASC;
I believe you can write the SQL with
ORDER BY offer_status, dadded
I'd like to know why INNER JOINs are generated instead of LEFT and why the whole view is selected before join instead of just adding LEFT JOIN view.
I'm trying to post a table of information which is spread out over several tables. Basically I want to search by the date and return all the information for events happening today, yesterday, this month - whatever the user selects. The query is quite long. I added DefaultIfEmpty to all the tables except the main one in an attempt to get LEFT JOINs but it just made a mess.
using (TransitEntities t = new TransitEntities())
{
var charters = from c in t.tblCharters
join v in t.tblChartVehicles.DefaultIfEmpty()
on c.Veh
equals v.ChartVehID
join n in t.tblNACharters.DefaultIfEmpty()
on c.Dpt.Substring(c.Dpt.Length - 1)
equals SqlFunctions.StringConvert((double)n.NAID)
join r in t.tblChartReqs.DefaultIfEmpty()
on c.ChartReqID
equals r.ChartReqID
join f in t.tblCharterCustomers.DefaultIfEmpty()
on c.Dpt
equals (f.DptID == "NONAFF" ? SqlFunctions.StringConvert((double)f.CustID) : f.DptID)
join d in t.tblChartReqDocs.DefaultIfEmpty()
on c.Attach
equals SqlFunctions.StringConvert((double)d.DocID)
join s in t.tblChartSupAttaches.DefaultIfEmpty()
on c.SupAttach
equals SqlFunctions.StringConvert((double)s.DocID)
join p in (from e in t.v_EmpData select new {e.UIN, e.First, e.Last}).DefaultIfEmpty()
on c.TakenUIN
equals p.UIN
where c.BeginTime > EntityFunctions.AddYears(DateTime.Now,-1)
select new
{
ChartID = c.ChartID,
Status = c.Status,
...
Website = r.Website,
};
//select today's events
gvCharters.DataSource = charters.Where(row => (row.BeginTime.Value >= midnight && row.BeginTime.Value < midnight1));
This results in very convoluted SQL:

This is what my original SQL query looked like and what I was hoping it would be closer to:
SELECT

c.Status,
...
r.Website As Website,

LEFT JOIN (SELECT [Dpt],[DptID] FROM [DRVRDiscipline].[dbo].[tblCharterCustomers] Where Valid=1 and DptID <> 'NONAFF' UNION SELECT Dpt, CONVERT(nvarchar,CustID) AS DptID FROM [DRVRDiscipline].[dbo].[tblCharterCustomers] Where Valid=1 and DptID = 'NONAFF') f
ON RTRIM(c.Dpt) = f.DptID LEFT JOIN [tskronos].WfcSuite.dbo.VP_ALLPERSONV42 p ON p.PersonNUM = c.TakenUIN
LEFT JOIN tblChartVehicles v ON v.ChartVehID = c.Veh
LEFT JOIN tblNACharter n ON CAST(n.NAID AS varchar) = RIGHT(c.Dpt, LEN(c.Dpt)-1)
LEFT JOIN tblChartReq r
ON r.ChartReqID = c.ChartReqID
WHERE CONVERT(datetime,CONVERT(char(10),c.BeginTime,101)) = (SELECT TOP 1 CONVERT(datetime,CONVERT(char(10),BeginTime,101)) from tblChartersNew WHERE CONVERT(datetime,CONVERT(char(10),BeginTime,101)) >= CONVERT(datetime,CONVERT(char(10),GETDATE(),101)) ORDER BY BeginTime)
AND NOT c.ChartReqID IS NULL
ORDER BY BeginTime, ISNULL(f.Dpt,c.Dpt)
I also add a Select New on the view to avoid selecting all of the columns when I only need three but it didn't seem to make a difference. Instead of adding LEFT JOIN v_EmpData it adds LEFT OUTER JOIN and then selects all of the columns in the view. It seems to be ignoring the Select New.
I'd really like to transition to using Linq to Entities for the majority of my queries because intellisense makes it so much easier to make sure it's right and to have variations of queries without having to have separate functions for each but maybe I need to stick with plain old SQL. I know just enough to make a big mess. Any suggestions?
For complex queries like what you need.
I would suggest looking into FunctionImport.
MSDN Function Import
This would save you the headache of creating a LINQ that would be 1:1 to your expected generated SQL.
