Joining Tables Through Multiple Criteria

Oct 14, 2013

I have two tables a and b, where I want to add columns from b to a with a criteria. The columns will be added by month criteria. There is a column in b table called stat_month which ranges from 1 (Jan) to 12 (Dec). I want to keep all the records in a, and join columns from b for each month. I do not want to loose any row from a if there is no data for that row in b.

Here is table a:

CREATE TABLE #A(
naics INT,
ust_code INT,
port INT,
all_qty_1_yr FLOAT,

[Code] ....

And here is table b:

CREATE TABLE #B(
naics INT,
ust_code INT,
port INT,
stat_month INT,
Cum_qty_1_mo FLOAT,

[Code] ....

I do not know how to have the multiple joins for 12 different months and what join I have to use. I used left join but still I am loosing not all but few rows in a, I would also like to know how in one script I can columns separately from stat_mont =’01’ to stat_month =’12’

/****** Script for SelectTopNRows command from SSMS ******/
SELECT a.[naics]
,a.[ust_code]
,a.[port]
,a.[all_qty_1_yr]
,a.[all_qty_2_yr]

[Code] ....

output should have all columns from a and join columns from b when the months = '01' (for Jan) , '02' (for FEB), ...'12' (for Dec): Output table should be something like

* columns from a AND JAN_Cum_qty_1_mo JAN_Cum_qty_2_mo JAN_Cum_all_val_mo JAN_Cum_air_val_mo JAN_Cum_air_wgt_mo JAN_Cum_ves_val_mo FEB_Cum_qty_1_mo FEB_Cum_qty_2_mo FEB_Cum_all_val_mo FEB_Cum_air_val_mo FEB_Cum_air_wgt_mo FEB_Cum_ves_val_mo .....DEC_Cum_qty_1_mo DEC_Cum_qty_2_mo DEC_Cum_all_val_mo DEC_Cum_air_val_mo DEC_Cum_air_wgt_mo DEC_Cum_ves_val_mo (FROM TABLE b)

Joining Tables With Multiple Criteria

Jun 9, 2014

I have a straight-forward select query to show work orders for a particular customer as below. I want to add a field value from another table, deltickitem diwhich contains contract records. I need to include the field di.weekchg to show the weekly hire rate, but the joined query must ensure that the both the contract number matches that in the original select and that the item number matches that in the actual select. Additionally, there is the problem that the item can appear more than once in the deltickitem table against a particular contract (if item has been off-hired and then re-hired on the same contract number) - in this case the query must select the record with the highest di.counter number, which I haven't worked out how to put in my query.

This is my basic code, but I keep ending up with duplicate work order lines in my result set.

Select wh.worknumber, wh.custnum, wh.contract, wh.sitename, wh.itemcode, wh.regnum, m.name, di.weekchg,
wh.date_created, wh.task_descr, wh.actual_labour_sale+wh.actual_parts_sale as [Repair Cost]
From worksorderhdr wh Left Join
inventory iv On iv.item = wh.itemcode inner Join
models m On m.id = iv.model_id left join deltickitem di on di.dticket = wh.contract
where wh.custnum = 'BARRATNE' and wh.rejected <> 1 and wh.charge_to_cust = 1
order by wh.date_created

Joining Multiple Tables In A View.

Dec 5, 2005

I have three tables
 
1st table is Student
StudnetID (pk)
Other fields…
 
2nd table is PhoneType
PhoneTypeID (pk)
PhoneType
 
3rd table is StudentHasPhone
SHPID (pk)
StudnetID (fk)
PhoneTypeID (fk)
PhoneNumber
 
PhoneType is an auxiliary table that has 5 records in it Home phone, Cell phone, Work phone, Pager, and Fax. Is there a way to do a join or maybe make a view of a view that would allow me to ultimately end up with…
 
StudnetID: 1
Name:  John
HomePhone: 123-456-7890
WorkPhone: 123-456-7890
CellPhone:
Pager:   123-456-7890
Fax:
Memo: This is one student record.
 
Some students will have no phone number, some will have all 5 most will have one or two. If possible I would like to do a setup like this in my database to keep from having to have null fields for 4 phone numbers that the majority of records won’t have.
Thanks in advanced,
Nathan Rover

Trouble Joining Multiple Tables

Dec 14, 2004

Hi,
This seems like a basic problem but I can't figure out how to resolve it.

I have a query :

SELECT PR.WBS2, SUM(LedgerAR.Amount * - 1) AS Expr5, LB.AmtBud AS budget
FROM PR LEFT OUTER JOIN
LedgerAR ON PR.WBS1 = LedgerAR.WBS1 AND PR.WBS2 = LedgerAR.WBS2 AND LedgerAR.WBS3 = PR.WBS3 LEFT OUTER JOIN
LB ON LB.WBS1 = PR.WBS1 AND LB.WBS2 = PR.WBS2 AND PR.WBS3 = LB.WBS3
WHERE (PR.WBS2 <> '9001') AND (PR.WBS2 <> 'zzz') AND (PR.WBS2 <> '98') AND (PR.WBS3 <> 'zzz') AND (PR.WBS2 <> '') AND (PR.WBS1 = '001-298')
GROUP BY PR.WBS2, LB.AmtBud
ORDER BY PR.WBS2


The output of the above query:

WBS2Expr5budget
0141
0141953000
0143
121724540
1217500
1217622.5800
12171000
12172000
12174000
12174500
121772908000
121793513500
12173445018000
12176596032000
12173801044000
121838100
121913224.5
1220
1221
122262000
12224000
122312702


I want to sum up the middle column and last column grouping by wbs2. However, when I do SUM(lb.amtbud) the budget column is not summing correctly it is summing the column as if the data appeared like this:

0141
01410101410101410103000
01410101410101410147.53000

0143

12170101217010121701008000
12170101217010121701008000
12170101217010121701008000
12170101217010121701008000
1217010121701012170101017.58000
121701012170101217010382.58000

121701012170101217010302.58000
12170101217010121701027.58000
121701012170101217010382.58000
121701012170101217010302.58000
1217010121701012170104958000
1217010121701012170102008000
1217010121701012170101017.58000
1217010121701012170101182.58000
1217010121701012170101952.58000
1217060
1217061
121708012170804000



So as a result I am getting 9000 where wbs2 = '0141'

I figure that in my top query I am not joining something correctly. Could someone point out what I am doing wrong?

Thank You.

:)

it works if we have a product in one color only. like if we have pant in red and blue then its showing just first record

Joining Multiple Tables With Conditions?

Mar 19, 2008



Hi,
I have a tbl called BANK.

This shows a banking history of transactions and includes a field called TransType and a field called PaymentID.


I also have two other tables called Suppliers and SubContractors.

For each record in the bank, I need to match up a record in either the suppliers or subcontractors tbl based on the PaymentID value. I know if the record relates to either a Supplier or Subcontractor based on the value of the TransType field which will be either SUPPLIER or SUBCONTRACTOR or Null (in which case a match doesn't matter)


I have a working query based on joining just the Supplier tbl.. but how do I do the join to the other tbl aswell?


So overall, for each record in the bank, if the transtype is SUPPLIER I need to look in the supplier tbl for a match for that paymentID, and if the transtype is SUBCONTRACTOR, I need to do the same but in SUBCONTRACTOR tbl.

How would I best write that?

thanks for any help!

Return Single Records By Joining Multiple Tables

Jun 4, 2008

I would like to know if it's possible to return a single record by joining the tables below. [Persons]
PersonID [int] | PageViewed [int]
=============== =================
1 10
2 5
3 2
4 12


[PersonNames] - PersonID JOINS Persons.PersonID
PersonID [int] | NameID [int] | PersonName [nvarchar] | PopularVotes [int]
=============== ============== ======================= ===================
1 1 Samantha Brown 5
1 2 Samantha Green 10
2 3 Richard T 10
3 4 Riko T 0
4 5 Sammie H 0


[AltNames] - backup for searches caused by common spelling mistakes
AltNameID [int] | AltNames [nvarchar]
================ =============================
1 Sam, Samantha, Sammie, Sammy
2 Riko, Rico


[PersonAllNames] - JOINS [PersonNames.NameID] ON [AltNames.AltNameID]
NameID [int] | AltNameID [int]
============= ================
1 1
4 1
3 2 
This is ideally what I'd like to have returned: PersonID | PageViewed | MostPopularName | NameSearch
========= ============ ================= =================
1 10 Samantha Green Samantha Brown, Samantha Green, Sam, Samantha, Sammie, Sammy
2 5 Richard T Richard T
3 2 Riko T Riko T, Riko, Rico
4 12 Sammie H Sammie H, Sam, Samantha, Sammie, Sammy
 
 
[MostPopularName] is [PersonNames.PopularVotes DESC].[NameSearch] combines all records from [PersonNames.PersonName] and [AltNames.AltNames].
 
The purpose for this is that I'd like to cache the results table so that all searches can just perform a lookup against the NameSearch field.
Any help would be greatly appreciated.
Thanks, Pete.

SQL 2012 :: Multiple Joining Tables - Duplicate Records

I have tried joining several tables and the result displays duplicate rows of virtually every line/row. I have tried using distinct but this didn't work. I know it could because there's several columns from some of the tables named the same.

We have the below query which is pulling in Sales and Revenue information. Since the sale is recorded in just one month and the revenue is recorded each month, we need to have the results of this query to only list the Sales amount once, but still have all the other revenue amounts listed for each month. In this example, the sale is record in year 2014 and month 10, but there are revenues in every month as well for the rest of 2014 and the start of 2015 but we only want to the sales amount to appear once on this results set.

Multiple Columns With Different Values OR Single Column With Multiple Criteria?

Aug 22, 2007

Hi,

I have multiple columns in a Single Table and i want to search values in different columns. My table structure is

col1 (identity PK)
col2 (varchar(max))
col3 (varchar(max))

I have created a single FULLTEXT on col2 & col3.
suppose i want to search col2='engine' and col3='toyota' i write query as

SELECT

TBL.col2,TBL.col3
FROM

TBL
INNER JOIN

CONTAINSTABLE(TBL,col2,'engine') TBL1
ON

TBL.col1=TBL1.[key]
INNER JOIN

CONTAINSTABLE(TBL,col3,'toyota') TBL2
ON

TBL.col1=TBL2.[key]

Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.

I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information.
for e.g.;
i was thinking to concatinate both fields like
col4= ABengineBA + ABBToyotaBBA
and in search i use
SELECT

TBL.col4
FROM

TBL
INNER JOIN

CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1
ON

TBL.col1=TBL1.[key]
Result = 1 row

But it don't work in following scenario
col4= ABengineBA + ABBCorola ToyotaBBA

SELECT

TBL.col4
FROM

TBL
INNER JOIN

CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1
ON

TBL.col1=TBL1.[key]

Result=0 Row
Any idea how i can write second query to get result?

Get Multiple MAX With Where Criteria

Mar 17, 2015

use of Row_Number() over ( partition... but I dont understand how.

Imagine I have a table like
CustomerID, PartNum, QtyinOrder, shipped
1 6 3 0
1 6 2 0
2 6 1 0
2 5 1 0
2 5 2 0
2 5 3 0
2 5 4 1
1 6 4 1
2 6 2 1

But I wanted to return

CustomerID, PartNum, MaxQtyOrderedNotShipped

That would be just the rows
1 6 3 0
2 6 1 0
2 5 3 0

If I use this:

Select CustomerId,PartNum, shipped, QtyInOrder AS MaxOrderedNotShipped
from
(SELECT [CustomerID]
,[PartNum]
,[QtyInOrder]
,shipped
, row_number() over (partition by [CustomerID], PartNum order by QtyInOrder desc) as recid from [SILK].[dbo].[MaxofGroup]) as f where recid =1

there is no restriction, so I get the shipped...If I alter the where clause to work only on not shipped, I get no records...as below

Select CustomerId,PartNum, shipped, QtyInOrder AS MaxOrderedNotShipped
from
(SELECT [CustomerID]
,[PartNum]
,[QtyInOrder]
,shipped
, row_number() over (partition by [CustomerID], PartNum order by QtyInOrder desc) as recid from [SILK].[dbo].[MaxofGroup]) as f where recid =1 and shipped=0

FilterExpressions With Multiple Criteria

Sep 10, 2007

I am creating a .aspx page that links with Miscrosoft SQL Server 2005 Express. It includes a GridView control that displays all the table data on the page. You can then select a record from the control (currently by clicking an image button to the left of each record- is there any way of selecting the record by clicking anywhere on the row? How would that be done?) and it displays the data in a detailsview control below where the data can be changed etc.
 The data is like a phonebook (Name, Telephone number, and some other misc fields) and the user should be able to search by either name or number to filter out the records shown in the gridview control. I have two textboxes for this, and I started with the name text box and it works fine. i.e. with one filterparameter and one filterexpression. So that if you just enter 'Da' it filters out the records displaying only those whose name starts with 'Da'.
 I have experimented but have found no way of including filter expressions to use the number as a search. I added the second filter parameter (under sqldatasource control so that:
 <FilterParameters>
<asp:ControlParameter Name="DestinationName" ControlID="txtName" /><asp:ControlParameter Name="DestinationNumber" ControlID="txtNumber" />
</FilterParameters>
But I don't know what to do for the FilterExpressions. currently I just have:
FilterExpression="DestinationName LIKE '{0}%'"
i have tried using "DestinationName LIKE '{0}%' OR DestinationNumber LIKE '{0}%'" but it requires that both text boxes have data entered.
 
What I want is something that allows the user to enter either a name or number or both (all or part of so don't need to enter in full name/number) and it filters out the records accordingly. I.e. if you enterd 'Dav' and '079' it would bring back all the records who had a name starting with Dav and a number starting with 079. However if you enterd just 079 then it should just bring back all records with numbers starting 079 whatever their associated name.
 
Thanks

Deleting With Multiple Criteria

Aug 27, 2004

I have a table with a record that looks like the attached TXT.


I need to keep the most recently entered value where flag_out = 1 and delete those duplicate
records, and this should only apply to records where there's also an flag_in value of 1.

I've tried a bunch of delete statements without avail....

TIA

How can you handle multiple criteria query in T-SQL ? i wrote selection query and in my where clause i have about 7 different criteria and for some reason when i run the query i do not get any error but i do not get any data return.

So is there any other way to handle multiple criteria in T-SQL ?

Multiple Update, Several Where Criteria

Nov 2, 2007



Im sorry if this has been covered, I tried a search but I couldnt seem to find what I was after.

Anyway, I need an Update procedure which is actually several bunched into one. Ive had a stab at it myself, and perhaps my pseudo SQL might explain what I need..




Code Block
UPDATE [TW].[dbo].[TBLSalesPart]
SET

CASE WHEN [Part] = 'MONTV-' AND [YN] = 'False' THEN [SubCategory] = 20440 END
CASE WHEN [Part] = 'TC-' AND [YN] = 'False' THEN [SubCategory] = 20444 END




Hopefully this makes sense, cheers..

Computed Column, IF, Multiple Criteria.

Jan 30, 2008

Hi.
 I have this method in a class, it produces a string value based on the value of another property in the object (which represents a field in the database). I would like to turn this into a computed column in SQL server... but need help converting the formula if this is even possible. Thanks in advance.public string GetVendorEvalRating(int vendorevaltotal)
{
string vendorevalrating = "";if (vendorevaltotal >= 26)
{vendorevalrating = "Critical";
}else if ((vendorevaltotal >= 10) && (vendorevaltotal <= 25))
{vendorevalrating = "Material";
}else if ((vendorevaltotal >= 0) && (vendorevaltotal <= 9))
{vendorevalrating = "Minor";
}return vendorevalrating;
}

Handling Multiple Search Criteria

Mar 20, 2012

I am working on SQL Server in VB 2008. I have a table 'Records' having 8 columns. I have a search page where I can choose 5 different parameters to search as 'Category' , 'Name' , 'Date' etc.

I can successfully search with a single criteria selected either Category Name Or Date. But I want to create a single SQL command that can search my 'Records' table for either two or all the parameters depending on the selections made by the user.

Counting And Grouping With Multiple Criteria

Jul 14, 2014

Consider the following dataset:

ID|MD|TYPE
1|JOHN|A
2|JOHN|B
3|JOHN|B
4|BOB|A
5|BOB|A
6|BOB|B
7|BOB|B
8|BOB|B

I need to count the number of IDs for each MD and each TYPE like this:

MD|A|B
JOHN|1|2
BOB|2|3

I only know how to count everything by MD like this:
SELECT MD, COUNT(ID) AS TOTAL
FROM MY_TABLE
GROUP BY MD
ORDER BY MD

The query above results in:

MD|TOTAL
JOHN|3
BOB|5

Output Search Criteria For Multiple OR?

Oct 21, 2014

My selection criteria is as follows:

where content like '%EditLiveJava%'
or content like '% Sys__%' ESCAPE '_'
or content like '%<div class="row"/>%'
or content like '%<a href="" title=""%'
or content like '%cmsprod%'
or content like '%Error processing inline link%'
or content like '%see log for stack trace%'

I output the content field if the search is true but would like to also output which specific 'like' has been found.

Can I do this in the one pass or do I have to read the database separately for each condition?

UPDATE Statement With Multiple Criteria

Apr 5, 2006

I am trying write a query to update a column of data in my xLegHdr table however the update is based on multiple criteria. I was trying to use "IF..ELSE" statements but that is not working.

I would like to update the "SMiles" column based on the data in the "Dist" column. If the number in the "Dist" column is less than 250 then subtract 25 and multiply it by 1.15 the result should go in the "SMiles" column. If the number is grater than 250 then subtract 40 and multiply by 1.15 and place the result in the "SMiles" column; like so:

UPDATE xLegHdr
SET SMiles =
IF Dist<250 THEN Round(Dist-25)*1.15)
ELSE Round(Dist-40)*1.15)
END IF

Any ideas?

Select Based Upon Multiple Criteria

Sep 13, 2006

Hi

I would like to get records from a table and present a result set based upon the search fields

the search fields could be any of the following: PNo, Year, JNo, C1No6, C2No3, C3No3, C4No3,

they could enter any combination of these however if they dont enter any of the above then the search should not retrieve any thing. the table colunms are listed below and asample data set is also shown below.

Currently the only way i think it can be done is by writing multiple queries with different queries to be executed based upon the search field that have been filled? can it be done in a stored prcedure? and can it be done using non-dynamic sql?

Name, PNo, Year, JNo, C1No6, C2No3, C3No3, C4No3, RefImage

Combining Multiple Rows Based Off Criteria

Mar 21, 2006

Hello again,

Another combining multiple rows teaser, during a few routines I made a mistake and I would like to combine my efforts. Here is my data:


Code:


Table A

ID DSN VN AX Diag
1111296.54
3212318.00



Both DSNs share the same Patient_id in a seperate table which holds the DSN numbers and their corresponding patients.


Code:


Table B

DSN Patient_id
100000001
200000001



So what I need to do is maintain their unique 'ID' number in Table A but update their DSN numbers to reflect the first instance in Table B. So my data would look like this in both tables.


Code:


Table A

ID DSN VN AX Diag
1111296.54
3112318.00

Note: The second rows DSN changed to 1 from 2




Code:


Table B

DSN Patient_id
100000001
(Duplicate row removed with same patient_id)



The result would look like the above but as you noticed I need to remove the duplicate row that had the different DSN in Table B so that only one DSN remains that can map to multiple rows (IDs) in Table A.

Table A:

DSN can map to multiple rows (IDs)
IDs must be unique (aka kept to what they are currently)

Table B:

Second row with same DSN must be removed.

Any takes, ideas? I need to do this on a couple thousand rows....

Thanks, and im happy to clarify if needed.

Query On Unique Records With Multiple Criteria

Oct 19, 2013

I'm fairly new in SQL. Been trying for months to create the right script for this particular case but still cannot give me 100% result as required.

SCENARIO :

I am required to query from 2 tables for those unique record that meets both conditions below:-
1. Status is 1 @ max (trans_id), paychnl = CC
2. Status is 2 @ max (trans_id), paychnl = A or B

FYR, 2 tables and respective columns to query are as below:-
table PTFF --> col ID, TRANS_ID,TRANSDATE,EFFDATE,TRANSCODE
table CHFF --> col STATUS,PAYCHNL

FYI, status refers to the paychnl method status:-
==> 1 means the current paychnl method
==> 2 means the previous paychnl method

paychnl method can be multiple because it will be defined as 2 for all the histories' paychnl chosen earlier, but 1 should only be unique as it is the latest paychnl chosen for each unique ID. however, it may appear more than once when it's taking those in earlier TRANSDATE, so here we would need the max trans_id as it will show the latest updated TRANSDATE.

Apart from that, I need only those most recent paychnl to be A or B and the latest paychnl is CC so, this been indicated by the same max trans_id for the same ID.

Aft trying so many times on this MAX command but failed to get any result, I only managed to come up to this part only. please refer below:-

table PTFF --> col ID, TRANS_ID,TRANSDATE,EFFDATE,TRANSCODE
table CHFF --> col STATUS,PAYCHNL

SELECT DISTINCT PTFF.TRANSCODE,PTFF.ID,PTFF.TRANS_ID,PTFF.TRANSDATE,PTFF.EFFDATE, CHFF.STATUS,CHFF.PAYCHNL

FROM DBO.PTFF PTFF
JOIN DBO.CHFF CHFF
ON CHFF.ID = PTFF.ID
WHERE
PTFF.TRANSDATE BETWEEN 130501 AND 130831
AND PTFF.TRANSCODE='T522'
AND (CHFF.STATUS=1 AND CHFF.PAYCHNL='CC' OR (CHFF.STATUS=2 AND (CHFF.PAYCHNL='A' OR CHFF.PAYCHNL='B')))

However, the script above returns :-

1. All those records with STATUS 1 regardless paychnl is A or B in most recent status 2,
2. Expected results also appear ==> 1 same ID with status 1 while paychnl=CC and status 2 while paychnl=A or B
3. Also duplicates of expected results but for different TRANSDATE and not at MAX TRANS_ID

Samples of the result:-

IDSTATUSTRANS_IDPAYCHNLTRANSDATEEFFDATETRANSCODE
51881712CC13082920130920T522
9361164CC13081620140813T522

Selecting Only 1 Record Based On Multiple Criteria

Jan 31, 2014

I have inherited a query which currently returns multiple instances of each work order because of the joined tables. The code is here and I've detailed the criteria needed below but need the best way to accomplish this:

Select h.worknumber, h.itemcode, h.descr, h.task_descr, h.qty, h.itemised,
h.serialnum, h.manufacturer, h.model_id, h.depot, h.date_in, h.date_approved,
h.est_complete_date, h.actual_complete_date, h.meterstart, h.meterstop,
h.custnum, h.name cust_name, h.addr1, h.addr2, h.town, h.county, h.postcode,
h.country_id, h.contact, h.sitename, h.siteaddr1, h.siteaddr2, h.sitetown,

[Code] ....

Each work order should only be returned once, and with the following additional criteria:

1. i.meter - this should return only the lowest number from that file.

2. sm.next_calendar_date - this should return only the most recent date out of those selected for the certificates on this piece of equipment

3. wh.meterstop as [Last Service Hours],
wh.date_created as [Last Service] - this should return the number from wh.meterstop at the most recent wh.date_created for that piece of equipment.

Update Records Matching Multiple Criteria

Feb 13, 2008

I have an 'update' query that looks like this:

update wce_contact
set blank = 'missing'
where website in ('www.name1.co.uk','www.name2.co.uk','www.name3.co.uk')

I know this query will set 'blank' to missing when it matches the above websites. However if i wanted to set blank to 'missing' where mail1date is not null and mail2date is not null (keep going to mail18date not null) how exactly would i go about this?

I guess it would be a case of adding another bracket somewhere but im unsure?

Aggregate Multiple Columns With Different SELECT Criteria

Sep 24, 2007

Let me start with saying thanks to all of you who have helped me (I'm a SQL newbee after doing OO for the past 12+ years)

I need to do several aggregates on multiple columns, with each column having different SELECT Criteria.

Sample Data:

Dept Project Cost CostFlag Schedule ScheduleFlag
D1 D1P1 495 1 135 3
D1 D1P2 960 2 70 2
D1 D1P3 1375 3 105 2
D1 D1P4 1050 2 160 3
D1 D1P5 1890 3 40 1

D2 D2P1 650 1 155 3
D2 D2P2 890 2 125 2
D2 D2P3 1235 3 85 1
D2 D2P4 430 1 140 3

D3 D3P1 1960 3 45 1
D3 D3P2 1490 3 85 1
D3 D3P3 1025 2 135 3
D3 D3P4 615 1 100 2
D3 D3P5 270 1 70 1
D3 D3P6 815 2 155 3

I need to calculate MEAN (average), Standard Deviation, Variance, Range, Span & Median for each data column (Cost, Schedule in the test data), where each data column has different selection criteria. I have the calculations working for each column individually (e.g. funcCalcCost, funcCalcSchedule), but I need to return the calculated values as a single data set:

SELECT Dept, Project, AVG(Cost) as Cost_Mean, MAX(Cost) - MIN(Cost) as Cost_Range, .......

WHERE CostFlag = @InputParameter

GROUP BY Dept, Project

The code above works great - but only for a single column. I need to return a dataset like this:
Dept Project Cost_Mean Cost_Range
D1 D1P1 495 135
D1 D1P2 960 70
D1 D1P3 1375 105

I need to return a dataset like this:

Dept Project Cost_Mean Cost_Range Schedule_Mean Schedule_Range
D1 D1P1 495 135 100 28
D1 D1P2 960 70 42 12
D1 D1P3 1375 105 91 38

I also have working code calculate the MEDIAN (what a pain that was, thank god I found a code example to get me going on the MEDIAN)

Thanks!
