CASE Statement Within Join
Oct 18, 2005Is it possible to have a join with case statement in it?
i.e.
select * from a inner join b on
case [x] then a.xid = b.xid
case [y] then a.yid = b.yid?

CASE Statement In A JOIN
Oct 16, 2007Hi, I have two tables TABLE_A and TABLE_BTABLE_A has rows like this:PROJECT_IDTASK_ID TASK_NAME1 100 One Hundred1 110 One Hundred Ten1 120 One Hundred Twenty2 200 Two Hundred3 300 Three Hundred3 310 Three Hundred TenTABLE_B has rows like this:PROJECT_IDTASK_IDAMOUNT1 10010001 11011002 NULL20003 3003000I want to inner join TABLE_A and TABLE_B such that if TASK_ID is available in TABLE_B, then join should happen on TASK_ID (on TABLE_A.TASK_ID=TABLE_B.TASK_ID), if TASK_ID is not available the join should happen on PROJECT_ID.For example for PROJECT_ID=2, there is no TASK_ID in TABLE_B (in this situation the join should be ON PROJECT_ID)How can we do a CASE like situation here?Thanks in advanceqA

Apr 24, 2007Hi,
I have a 2 different telephone number tables,
Table 1 has some numbers beginning with '0' i.e. 08001234567 and some without the '0' i.e 8001234567
on my Table2 i only have numbers starting with '0' i.e 08001234567.
I would like to make a INNER JOIN statement and check if the telephone number dont have a starting '0', then append to it and try to do the join so I get both set of data.
for example (this doesnt work however...):
SELECT *
FROM dbo.Calls INNER JOIN
ON
CASE WHEN SUBSTRING(dbo.CallData.TelephoneNumber, 0, 1) = '0'
THEN dbo.Calls.TelephoneNumber = dbo.Post.TelephoneNumber
ELSE '0' & dbo.Calls.TelephoneNumber = dbo.Post.TelephoneNumber <--append a 0 at the start
END CASE
AND dbo.Products.FK_Client = dbo.CallDataSets.FK_Client
GROUP BY dbo.CallDataSets.FK_Client
I hope you understand what I am trying to achieve here...
Any help is appreciated!
Many thanks,
Jon
How To Use Case Or If Statement In Inner Join ?
Sep 26, 2007Hi All,
I am in need for to write the following query for a stored procedure in SQL Server 2000. Please observe the T-SQL code first.
Please disregard the numbers and Product Numbers, they are not the correct data. I used them for ease of understanding. But the query is identical.
Code Block
SELECT
C.iOwnerid,
MAX (C.DtInsertDate) AS [dtLastIssueDate]
INTO #Tble
FROM CustomerProduct C
CASE WHEN @vchSubscription = 'Weekly' THEN
INNER JOIN ProductMaster PM ON PM.chProductNumber = C.chProductNumber
AND ( ( PM.vchUser7='101557' AND PM.vchUser8='101557' ) -- Category and SubCategory
OR PM.chProductNumber IN (
'weekly1', 'Weekly2', 'Weekly3', 'Weekly4' )
)
AND C.dtInsertDate > = @dtIssueDate CASE WHEN @vchSubscription = 'Monthly' THEN
INNER JOIN ProductMaster PM ON PM.chProductNumber = C.chProductNumber
AND ( ( PM.vchUser7='101557' AND PM.vchUser8='101557' )
OR PM.chProductNumber IN (
'Jan', 'Feb', 'Mar', ....'Dec')
)
AND C.dtInsertDate > = @dtIssueDate
END
GROUP BY C.iOwnerid, PM.vchUser7, PM.vchUser8
my requirement is join the same table, but depending on the subscription type i have to join to different product numbers.
I hope you understand. I have been trying this since yesterday, but no luck.
Any help would be greatly appreciated.
T-SQL (SS2K8) :: Statement Using Case And Join Together
Jan 29, 2015I am trying to use this logic into a query:
Select P.S,E.S,E.R

on E.R is null
case when E.R is not null then ''
else ''

Using A Case To Decide On The Join Statement?
Jun 22, 2006I'm trying to join a table and based on the value of a given column I would join using the column in question, however if the column is NULL then I want to make the join without the column in the join. so I think I want to do something like this:
Case E.a
when NULL
then LEFT JOIN EPD ON EPD.b = D.b
AND EPD.SD = (SELECT MAX(E1.SD) FROM E1
WHERE E1.b = EPD.b AND E1.a = EPD.a AND E1.SD <= T.WD)
Else
LEFT JOIN EPD
ON EPD.a = D.a
and EPD.b = E.b
AND EPD.SD = (SELECT MAX(E1.SD) FROM E1
WHERE E1.a = EPD.a AND E1.b = EPD.b AND
E1.SD <= T.WD)
end
however T-Sql does not seem to like my Case statement mixed into my From/join clauses.
Thanks,

SQL Server 2008 :: Optimizing Join With CASE Statement
Jul 20, 2015I have data that I want at multiple granularities, 5,15,30 and 60 minutes. To reduce repetition, I have put them all in the same table, so that there is a column for 5,15,30 and 60 minutes, with a filtered index on each of the columns that removes the nulls. This means that each day will have 288 slots, but only 24 of the slots are filled in for 60 min data, and all of them are filled for 5 minute data.
I have another column that specifies the interval granularity, and my first thought was to access my data through a join, where I can use a CASE statement, and depending on the data granularity necessary, it will look at a different column:
INNER JOIN Data d ON
AND d.settlement_key =
CASE st.interval_granularity
WHEN 5 THEN [5_min_settlement_key]
WHEN 15 THEN [15_min_settlement_key]
WHEN 60 THEN [60_min_settlement_key]
ELSE NULL END
Despite the presence of the indexes on the columns, then the process seems to be quite slow, I think probably due to the fact that any query plan isn't going to know beforehand which of the columns it is going to use for any given dataset, until it actually starts to run, so it may not be optimised.
How I could optimise this based on the given structure? Maybe there are hints to be added to the join, or maybe I can clear the query plan each time the SQL is run? My other option for dealing with the data of different granularity was to use one column and repeat the data multiple times, each at the different granularity, but this makes my data, row and table sizes much higher, as we are adding just a column for each additional granularity. Would this work any better in future versions of SQL server, maybe with column store indexes?
Problem Using Result From CASE In Another CASE Statement
Nov 5, 2007I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.
Previously, I had been duplicating the CASE logic for both columns, like so:
Code Block...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE
[logic for condition 1]
THEN 'Condition 1 text'
WHEN [logic for condition 2]
THEN 'Condition 2 text'
WHEN [logic for condition 3]
THEN 'Condition 3 text'
WHEN [logic for condition 4]
THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.
This is what I'd like to do:
Code Block
...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE shipment_status
WHEN 1 THEN 'Condition 1 text'
WHEN 2 THEN 'Condition 2 text'
WHEN 3 THEN 'Condition 3 text'
WHEN 4 THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.
Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?
Thanks,
Jason

Multi-table JOIN Query With More Than One JOIN Statement
Apr 14, 2015I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table.
The makeid and orderdate belong to the OrderDetails table.
The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
Case Statement Error In An Insert Statement
May 26, 2006Hi All,
I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance.
My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.
Here is my code:
Insert into myTblA
(TblA_ID,
mycasefield =
case
when mycasefield = 1 then 99861
when mycasefield = 2 then 99862
when mycasefield = 3 then 99863
when mycasefield = 4 then 99864
when mycasefield = 5 then 99865
when mycasefield = 6 then 99866
when mycasefield = 7 then 99867
when mycasefield = 8 then 99868
when mycasefield = 9 then 99855
when mycasefield = 10 then 99839
end,
alt_min,
alt_max,
longitude,
latitude
(
Select MTB.LocationID
MTB.model_ID
MTB.elevation, --alt min
null, --alt max
MTB.longitude, --longitude
MTB.latitude --latitude
from MyTblB MTB
);
The error I'm getting is:
Incorrect syntax near '='.
I have tried various versions of the case statement based on examples I have found but nothing works.
I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.

SQL Late Join With Case - Help...
Feb 6, 2006All - I'm having some trouble, and I hope someone can give me some assistance. I've scoured Google, and have only found stuff similar to what I already have.
My company has an old commercial ERP package. The package has a table called 'Lot_Bin_Tran' that tracks movements of parts based on the part number and a 'Tran_code' - a one-character field that represents what kind of transaction it is (receipt, shipment, inventory adjustment, etc...). Using those two pieces of information, you can join this single table to any of the tables that hold the information (such as receipts). I tried to write a left join from my transaction table to my primary tables to look for transaction records that have no corresponding records in the primary tables. Some SQL might be helpful here...
Code:
SELECTLBT.*
FROMLOT_BIN_TRANLBT(NOLOCK),
PRODUCEP(NOLOCK),
ORDERSO(NOLOCK),
ISSUESI(NOLOCK),
RECEIPTSR(NOLOCK),
LOT_BIN_XFERLBX(NOLOCK)
WHERELBT.PART_NO = 'OUR_PART_NUMBER_GOES_HERE'
AND
LBT.TRAN_NO *=
CASE LBT.TRAN_CODE
WHEN 'I' THEN I.issue_no
WHEN 'P' THEN P.prod_no
WHEN 'R' THEN R.receipt_no
WHEN 'S' THEN O.order_no
WHEN 'T' THEN LBX.tran_NO
END
AND
((I.ISSUE_NO IS NULL) AND (P.PROD_NO IS NULL) AND (R.RECEIPT_NO IS NULL) AND (O.ORDER_NO IS NULL) AND (LBX.TRAN_NO IS NULL))
when I run this, though - I get the following message...
Quote:
Msg 301, Level 16, State 1
Query contains an illegal outer-join request.
If I change the Left join to an inner join (using = instead of *=), I get a resultset, but not the one I want (since I can't detect nulls in all tables using inner join). Any ideas on how I can restructure?
Thanks!
Case Inside A Join?
Mar 4, 2014Is it possible to do something like this:

It gives a syntax error but I'm wondering if there's another way to do it.
Case Expression Plus Outer Join In Ole Db Source
Oct 26, 2006I'm trying to generate the data for a 2-column table, where both columns are defined as NOT NULL and the second column is a uniqueidentifier.
In SQL Server Management Studio, this works fine:insert into table_3(column_a, column_b)
select table_1.column_a, (case when table_2.column_b is NULL then newid() else table_2.column_b end) as column_b
from table_1 left outer join table_2 on table_1.column_c = table_2.column_c
That is, column_b of the SELECT result has no NULL values, and all 35,986 rows are successfully inserted into a previously empty table_3. (If I comment out the INSERT INTO clause and project table_2.column_b instead of "(case ... end) as column_b", the SELECT result includes 380 rows with a NULL in column_b, so I know the case expression plus the outer join are working as expected.)
But when I use the SELECT query as the SQL command in an OLE DB Source component that is connected directly to the OLE DB Destination for the result table, I get this error:There was an error with input column "column_b" (445) on input "OLE DB Destination Input" (420
The column status returned was: "The value violated the integrity constraints for the column.".
And sure enough, when I modify the result table to allow NULL in column_b, truncate it, and re-run the data flow, it inserts the exact same 380 rows with a NULL in column_b among the 35,986 rows.
So what is SSIS doing to screw up the results of the SELECT command???
SELECT Query Including JOIN And CASE Expression
Aug 12, 2012An error is entered into the table, across two tables - tblErrors_ER and tblPolicyNumbers_ER - each error generates a PK (ErrorID) and can have any number of policy numbers which will be referenced by its own PK but linked to each error by its FK (ErrorID).I want to display each error in a Gridview in ASP.Net - columns included will be ErrorID, ErrorType, DateLogged from tblErrors_ER and PolicyNumber from tblPolicyNumbers_ER.If an Error has more than one policy number I only want to show the error once in the GridView with the word MULTIPLE under policy number.
tblErrors_ER
---------------
CREATE TABLE tblErrors_ER
{
ErrorID int,
ErrorType varchar(255),
DateLogged datetime,
[code]...
I have changed the Count(*) to Count(tblPolicyNumbers_ER.POlicyNUmber) which gives me the same undesired result as above. I have also left it as Count(*) and the entire CASE expression within the GROUP BY statement as suggest above which generated an error saying I can not use an expression in a group by clause.
If I leave Count(*) = 1 where it is in the original SELECT statement but swap the = for > then something happens, close to what I require but not as intended. It returns:
ErrorID ErrorType DateLogged PolicyNumber
---------------------------------------------------------------
1 Test 08/08/2012 Multiple
2 Test 08/08/2012 Multiple
this would suggest the original syntax is close to being accurate but I can not get it to work.

Jun 2, 2005Hi all,
I was wondering if there is any way in an sql statement to check whether the data your trying to get out of the DB is of a particular type, ie. Int, char etc. I was thinking about a case statement such as
<code>
CASE WHEN (MyNum <> INT) then 0 end AS MyNum
</code>
This has to be included in the sql statement cause I need this field to get other data.
Any thoughts on how to achieve this would be greatly appreciated.
If I’m in the wrong thread section please advise of best one to get help in.
What Is The Best SQL Statement For This Case ?
Sep 17, 2005Hi !!!i hope one of the sql specialists answer me about the best and most effeceint way to acheive what i am looking for Scenario:-------------i have a 3 tables related to each other Addresses, Groups and GroupAddressthe relation is for both addresses and groups is one to many in the GroupAddress.the behaviour in the application : user can add addresses to his address list and from the address list a user can add an address to many groups like if you have Group name "Freinds" and you add me in it and you have Football team group and you add me to it like that !!!not i have another function called "copy group"in the GroupAddress i have this data as example GroupID AddressID1 41 61 21 441 72 82 62 93 133 73 10and the group ID called "Freinds"i want to copy the group so i can have another group that has the same addresses by one click rather than collectiong them again one by one ...by the way the new copy will have a new group name ( as this is thebusiness logic so user can not have dupicate group name )so what is the best SQL statement that i need to copy the group ???i hope that clear enough!

I could like to use a Case statement to determine if there is Null. If so, then output N/A in place of the Null. So then my possible valus are Yes, No, and N/A.
Any clues?

Basically, i ahve to use one condition to get corrrect output related to inputs:
like - i have to input @category varchar(50), @category_value varchar(50)
and if category = 'campaign' then category_value = ''
then output should be itemnmbr sum(totalcount) [whatever should be custclas or custclasdesscription]
itemnmbr sumcount
-----------------
06-5840 52
06-541 101
06-452 26
kr-045 252
and if categroy = 'item' then category_value = any itemnmbrs(06-5840,06-5845,06-5841 etc..)
then output should be
itemnmbr custclas custclasdescription totalcount

thanks a lot!!
create function fntotalcountcustclas

Case Statement
May 5, 2008Im running the following sql statement but I dont see the
expected output. There are few differences between acc & cl1, mcc & cl2 , ncr & cl3 but I dont see either 'ONE' or 'TWO' or 'THREE'.
There is even a case where cl3 is null but the sql is not filling in either one or two or three. Query simply returns id & rest as null values.
SELECT P1.id,
CASE
WHEN p1.acc!= p1.cl1 then 'ONE'
WHEN p1.mcc!= p1.cl2 then 'TWO'
when p1.ncr!= p1.cl3 then 'THREE'
Else NULL END
As NOnMatchingColumn
from
(select id, acc, cl1,mcc,cl2,ncr,cl3 from dbo.ml)P1
Help With Case Statement
Jun 6, 2008I'm not sure if I am doing this the right way. In my table I have project ids. Each project id has several activities associated with it. Each project has a starting balance. Each activity posts an expense to the total balance of the project. If the project has enough money to handle the charges made by the activities, all the activity expenses can be "posted". If there isn't enough money, I want to loop through the activities, check to see if there is enough of a balance to "post" the first one, If there is, then I want to re-adjust the balance and check the second activity. I want to scroll through each project/activity to see what can be "posted". Here is what I have so far, but I cannot work out how to change the total balance amount. Hopefully what I am trying to do makes sense!
declare @testId nchar(6)
declare @RowNum int
declare @newBalance int
select top 1 @testId=projID from #ProjIds
set @RowNum = 0
WHILE @RowNum <= (Select Max(temp_id) from #ProjIds)
BEGIN
set @RowNum = @RowNum + 1
set @newBalance = (select top 1 Bal_2300
from #RevRecData
where @testId=projId
order by projID, activity)
select projId, activity, postCr, Bal_2300,
'New_Status' = Case when (postCr <= Bal_2300) then 'Can Clear' else 'Still Check' END,
'New_Balance' = Case when (postCr <= @newBalance) then (@newBalance - postCr) else @newBalance End
from #RevRecData
where @testId=projId
order by projID, activity
select top 1 @testId=projId from #ProjIds
where projId > @testID
END
