Case Statement Within A Select Where 2 Or More Instances Of The Record Exist.
Jul 23, 2005
Ok,
I have a data warehouse that I am pulling records from using Oracle
SQL. I have a select statement that looks like the one below. Now what
I need to do is where the astrics are **** create a case statement or
whatever it is in Oracle to say that for this record if a 1/19/2005
record exists then End_Date needs to be=1/19/2005 else get
End_Date=12/31/9999. Keep in mind that a record could have both a
1/19/2005 and 12/31/9999 instance of that account record. If 1/19
exists that takes presedent if it doesnt then 12/31/9999. The problem
is that the fields I pull from the table where the end_date is in
question change based on which date I pull(12/31/9999 being the most
recient which in some cases as you see I dont want.) so they are not
identical. This is tricky.
Please let me know if you can help.

I have table Products and Orders that has the following columns:
table Products: ProductID, ProductName
table Orders: OrderID, ProductID, OrderDate, Quantity, Price
The Orders table contains orders placed on all the dates. I want to obtain a list of orders for a particular date, if there is no order for a product on the requested date, I want to return null values for the Quantity and Price fields.
I tried the following select statement:
select Products.ProductName, Orders.Quantity, Orders.Price from Products left join Orders on Products.ProductID = Orders.ProductID where Orders.OrderDate = '10/16/2004'
Where, there are a total of three products (A,B,C) in table Products. Product-C has no order on 10/16/2004, but I want it to return :
ProductName / Quantity / Price
Product-A 5 1.89
Product-B 6 2.43
Product-C null null
Obviously, my sql statement won't work becaue the where clause will filter out Product-C.
Could anyone help me figure out how to modify my sql code to get the resultset I want?
Thanks in advance.

Hey guys, i'm trying to use a CASE within a select but i'm not sure how to get started.
Here is my select so far, i'm inserting into a temp table that is used within a loop to gather data from my trigger:
Code:
insert into @temp_par
select CONVERT(varchar(20),d.PAT_ID),
ep.EXT_PAT_ID,
d.DRUG_DESC_ID,
d.ALLERGY_CD,
CONVERT(varchar(20),d.PAR_DT,120),
ISNULL(d.PAR_TXT, 'NULL'),
ISNULL(REPLACE(m.DRUG_NM,'"','^"'),'NULL'),
ISNULL(m.DOSAGE_FORM_CD,'NULL'),
ISNULL(m.STRGTH,'NULL'),
ISNULL(m.STRGTH_UM,'NULL')
from deleted d --PATIENT_PRIOR_ADVERSE_REACTIONS
join EXTERNAL_PATIENT ep on ep.PAT_ID = d.PAT_ID
join MEDNAME m on m.DRUG_DESC_ID = d.DRUG_DESC_ID
I would like to use a CASE for the d.ALLERGY_CD column. The data in this column is usually a 1,2,3,4,5 but i'd like to convert those to their real data, for example:
Code:
1 = A
2 = B
3 = C
4 = D
5 = E
Any help?

Limitations: Needs to be single sql statement for exec, no udf/stored proc
Objective: select aggregate count from tblPerson grouped by s_fk, division,Desc, areaDesc with rollup for totals
if mail_goes_to=1, get the s_fk value via tblPerson/tblAffiliation/tblOrg/tblCity/tblCounty
if mail_goes_to=2, get the s_fk value via tblPerson/tblCity/tblCounty, skipping tblAffiliation/tblOrg
What's the best method? A case statement? Would a cross-join work? Thanks so much for any and all advice!
tblPerson: person_pk, affiliation_fk; home_city_fk, mail_goes_to
tblAffiliation: affiliation_pk, organization_fk
tblOrg: organization_pk, city_fk
tblCity: city_pk, county_fk
tblCounty: county_pk, s_fk
For resulting display only:
tblPersonArea: personArea_pk, area_fk, person_fk
tblArea: area_pk, areaDesc, division_fk
tblDivision: division_pk, divisionDesc

Hi,
I'm wondering what syntax to use for a select case statement.
I have a list of questions. If a particular question is on the list, then it shouldn't show some other related questions.
For example, "have you been in the military?". If you haven't , then you wouldn't be asked all the military related questions.
So- I'm saying:
select case when question_id = 488 then don't return question_id 220, 962, 963
I'm trying something like this:
select q.client_id,
case when q.question_id = 488 then end q.question_id = 220 else q.question_id = 220 end q.question_id
from questions_yes_no q
How would I say 'dont show' question 220? End is not the way to go, obviously.
If you can see what I'm trying to do, can you point me to an article or bol search?
Thank you for any help.

Hi,I am wondering how do I write a query that will take case sensitive into consideration. For example, I have "ABCD", "abcD", ABcd", "AbCd" in a table. I want to retrieve "AbCd" only from the table. This is the sql statement that I have:sqlSelect = "SELECT * FROM [al_table] WHERE [alphabet]= @alpha"Dim selectCmd As New SqlCommand(sqlSelect, myConnection) selectCmd.Parameters.AddWithValue("@alpha", "AbCd") From what I have it will return all those value. But that is not what I want. Thanks

Hi All,
I need a hand in this script.
SELECT a.id ,value = CASE
when (x1-x0) = 0 then
((Y2-Y0)-(Y1-Y0))/(0.000000001*(X2-X0))
ELSE
((-111.48277-Y0)-(Y1-Y0))/((X1-X0)*(32.72383-X0))
END
,value2 = CASE
when (x1-x0) = 0 then
((Y2-Y0)-(Y1-Y0))/(0.000000001*(X2-X0))
ELSE
((-111.48277-Y0)-(Y1-Y0))/((X1-X0)*(32.72383-X0))
END
FROM table_name a
where value > 0
ORDER BY VALUE
The problem I'm having is in the where clause. Because the value is not a column name sql server is giving me an error. I need to evaluate the value returned. How can I get around this problem? Any sort of advise will help!
Thank you in advance!

Hi folks,
Hope you are all well.
I am using a CASE statement within a SELECT query to sum up values for different customers.
SELECT CR_CUST.Customer_Code,
'General_01' = CASE WHEN CR_PROD.Part_Class_Code = '01' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END,
'General_07' = CASE WHEN CR_PROD.Part_Class_Code = '07' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END,
'General_08' = CASE WHEN CR_PROD.Part_Class_Code = '08' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END
FROM CR_CUST
INNER JOIN CR_INVOICE ON CR_CUST.Customer_Code = CR_INVOICE.Customer_Code
INNER JOIN CR_PROD ON CR_INVOICE.Product_Code = CR_PROD.Product_Code
WHERE (CR_PROD.Part_Class_Code = 1 OR
CR_PROD.Part_Class_Code = 7 OR
CR_PROD.Part_Class_Code = 8)
GROUP BY CR_CUST.Customer_Code,
CR_PROD.Part_Class_Code
The above query produces the following results...
Customer_Code General_01 General_07 General_08
------------- ---------------- ---------------- ----------------
02210 10074.30 .00 .00
02347 7606.49 .00 .00
02210 .00 12618.42 .00
02347 .00 13131.63 .00
02210 .00 .00 4505.44
02347 .00 .00 5018.03
My question is this - is it possible to expand my SQL Query into a Sub Query so that each customers data appears on the same line of the results?, like so...
Customer_Code General_01 General_07 General_08
------------- ---------------- ---------------- ----------------
02210 10074.30 12618.42 4505.44
02347 7606.49 13131.63 5018.03
I can achieve this by writing my results into a temporary table and extracting the data with the following SQL Query, but I just thought it would be really cool if I could do it in one SQL Statement without using a temporary table.
SELECT Customer_Code,
SUM(General_01),
SUM(General_07),
SUM(General_08)
FROM #MyTempTable
GROUP BY Customer_Code
Thanks in advance,
Kev

As you can see it should return castedValue as integer but it cast to datetime which is wrong. If I commented line
Code Block
when me.ElementTypeId =4 then cast(mev.ElementValue as datetime)
it casts everything normal, but as soon as it has more than one condition in CASE it will choose anything but not right casting
Looks like I am missing something really fundamental. Any help is apreciated !
Thanks

Hi, I have created a login page (webform1) that enables me to enter my user number and password and if correct it re-directs to webform 2 where all data related to the usernumber that was entered in the login page, appears. Now I want to be able to set different re-direct pages dependant upon different users as some may require more privileges then others. As for my query I have 2 types of users: staff and managers. I want to set the login page so that if staff logins in it goes webform 3 and if manager logins in it goes webform 4. My table in the Sql database is called Users & the fields are: unumber(pk), pwd, userRole, forename, surname. I have been advised to use CASE statements, yet I do not know how to use them.

I need to perform an update where there are multiple scenarios which determine the value that is entered. Below is a sort've psuedo code of how it needs to be.
Update MyTable SET MyColumn = CASE WHEN MyCol1 = 'Value1' Then NewValue Else
WHEN MyCol1 <> 'Value1' And MyCol2 = 'Active' Then 'Value1'
In the scenario where MyCol1 <> Value1 and MyCol2 <> 'Active' then no update would occur and the original value would remain intact.

I am selecting the count of the students in a class by suing select COUNT(studentid) as StCount FROM dbo.student But I need to use a case statement on this like if count is less than 10 I need to return 'Small class' if the count is between 10 to 50 then I need to return 'Medium class' and if the count is more than 50 then 'Big class'.
Right now I am achieving this by the following case statement
SELECT 'ClassSize' = CASE WHEN Stcount<10 THEN 'Small Class'
WHEN Stcount>=10 and StCount<=50THEN 'Medium Class'
WHEN Stcount>50 THEN 'Big Class'
END
FROM(
select COUNT(studentid) as Stcount FROM dbo.student) Stdtbl
But can I do this with just one select statement?

I am fairly new with SQL and still learning. I have used a case statemtent for a column in my select list and want to use the results of that statement's field in my WHERE clause but it is not working for me. Here is the code I have so far:
SELECT
l.loanid,
p.investorid,
l.duedate,
case when pc.duedate >= l.duedate then pc.duedate end as RateDueDate,
pc.interestrate
FROM loan l
inner join participation p on p.loanid = l.loanid
inner join paymentchange pc on pc.loanid = l.loanid
where p.investorid = '12345' and RateDueDate is not null
order by l.loanid, pc.duedate
I want to put the results of this case statment in my where clause like highlighted above but it is not working because RateDueDate is not an actual column in the table. Any help would be greatly appreciated.
Thanks!

I have scenario where i have to pick one particular value from where condition. Here is the example:A store can have different types i-e A or B , A and B or either A or B.
Store Type Sales
11 A 1000
23 A 1980
23 B 50
5 B 560
I want to filter the store in "where clause" where
1)- if the store has type A and B, then assign only A
2)- if the store has type A associated with it then assign A
3)- if the store has type B associated with it, then assign B.
Select Store, sum(sales), Type
from table1
where (TYPE]= (case when [TYPE] in ('A','B') then 'A'
when [TYPE]='A' then 'A' else 'B'end))
GROUP BY [store], [TYPE]
The above statement is not working for when store has only Type B associated with it.

Hi guys,
anyone can help me?
i using sp to select a select statement from a join table. due to the requirement, i need to group the data into monthly/weekly basic.
so i already collect the data for the month and use the case to make a new compute column in the selete statement call weekGroup. this is just a string showing "week 1", "week 2" .... "week 5".
so now i want to group the weekgroup and disply the average mark. so i need to insert all the record from the select statement into the temporary table and then use 2nd select statement to collect the new data in 5 record only. may i know how to make this posible?
regards

Is that possible to restrict inserting the record if record already exist in the table.
Scenario: query should be
We are inserting a bulk information of data, it should not insert the row if it already exist in the table. excluding that it should insert the other rows.

I have an Address column that I need to Substring. I want to remove part of the string after either, or both of the following characters i.e ',' OR '*'
Example Record 1. Elland **REQUIRES BOOKING IN***
Example Record 2. Theale, Nr Reading, Berkshire
Example Record 3. Stockport
How do I achieve this in a CASE Statement?
The following two case statements return the correct results, but I some how need to combine them into a single Statement?
,LEFT(Address ,CASE WHEN CHARINDEX(',',Address) =0
THEN LEN(Address )
ELSE CHARINDEX(',' ,Address ) -1 END) AS 'Town Test'
,LEFT(Address ,CASE WHEN CHARINDEX('*',Address ) =0
THEN LEN(Address)
ELSE CHARINDEX('*' ,Address ) -1 END) AS 'Town Test2'

Hey gang,
I've got a query and I'm really not sure how to get what I need. I've got a unix datasource that I've setup a linked server for on my SQL database so I'm using Select * From OpenQuery(DataSource, 'Query')
I am able to select all of the records from the first two tables that I need. The problem I'm having is the last step. I need a field in the select statement that is going to be a simple yes or no based off of if a customer number is present in a different table. The table that I need to look into can have up to 99 instances of the customer number. It's a "Note" table that stores a string, the customer number and the sequence number of the note. Obviously I don't want to do a straight join and query because I don't want to get 99 duplicates records in the query I'm already pulling.
Here's my current Query this works fine:
Select *From OpenQuery(UnixData, 'Select CPAREC.CustomerNo, CPBASC_All.CustorCompName, CPAREC.DateAdded, CPAREC.Terms, CPAREC.CreditLimit, CPAREC.PowerNum
From CPAREC Inner Join CPBASC_All on CPAREC.CustomerNo = CPBASC_All.CustomerNo
Where DateAdded >= #12/01/07# and DateAdded <= #12/31/07#')
What I need to add is one more column to the results of this query that will let me know if the Customer number is found in a "Notes" table. This table has 3 fields CustomerNo, SequenceNo, Note.
I don't want to join and select on customer number as the customer number maybe repeated as much as 99 times in the Notes table. I just need to know if a single instance of the customer number was found in that table so I can set a column in my select statement as NotesExist (Yes or No)
Any advice would be greatly appreciated.
