Transact SQL :: Case Statement In Where Clause - Select First / Default Value If Two Different Value Exists

Nov 16, 2015

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.

Transact SQL :: Case Statement In Update Clause

Jun 4, 2015

I have used the below update query. However, its updating only the first value. Like its updating AB with volume when c.Type  = ABC, similarly for CD. Its not updating based on the 2nd or the next case condition.
 
Update XYZ Set AB = a.Amt * (CASE WHEN c.Type = 'ABC'  THEN  (c.volume)
 WHEN c.TYPE = 'DEF'  THEN  (c.volume)
 WHEN c.Type = 'GHI'  THEN  (c.volume)
 Else 0
 END),
 CD = CASE WHEN c.Type = 'MARGIN' THEN '4105.31'
 WHEN c.Type = 'ABC' THEN '123.1'
 WHEN c.Type = 'DEF' THEN '234.2'
WHEN c.Type = 'GHI' THEN '567.1'
END
 from table1 a join table2 b
 on a.Cust = b.Customer
 join table3 c
 on b.account = c.account and b.channel =c.channel

Why its not working properly? But if i use Select statement instead of update query its working properly.

Trying To Use The Results Of A Case Statement In My Select List In My WHERE Clause?

Aug 10, 2006

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 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

In the scenario where MyCol1 <> Value1 and MyCol2 <> 'Active' then no update would occur and the original value would remain intact.

Transact SQL :: CASE Expression In WHERE Clause?

Nov 6, 2015

I have a scenario where the End User is going to select two parameters.  @AgentID and @Location If the End User selects @AgentID parameter, in my WHERE clause, I do not want to check the location condition. By default, the agent knows their location already.

If the End User select @Location parameter, in my WHERE clause, I still want to check the Agent condition.

@AgentID parameter would populate either with "All" or their actual agent# (76754 for example).

@Location parameter would populate either with "All" or their actual location (Birmingham or Bessemer for example)Sample of my current WHERE clause:

WHERE
 
 gl.ReceiptDate >= @BeginDate and gl.ReceiptDate < DATEADD(D,1,@EndDate)
 AND gl.AgentId = CASE WHEN @AgentID = 'All' THEN gl.AgentID ELSE @AgentID END
 AND gl.Location = @Location

Using Case Statement With WHERE Clause...

Feb 21, 2008

Hi,
I need help to use CASE Statement within my WHERE Clause. I want to change the WHERE Clause based on my condition as following:
SELECT ...
FROM ...
WHERE  (condition)
AND       (condition)
AND       (condition)
AND       (
                    CASE Table.Category
                          WHEN 'Drinks' THEN
                               Table1.Field1 = 1 -- Problem line
                          ELSE
                               Table1.Field1 = 1 AND Table1.Field2 = 1 -- Problem line
                   END
             )
In the above case, my WHERE Clause is dependent on one of the fields in a table. If it has a certain value then only Table1.Field1 is used otherwise Table1.Field1 & Field2 come into action.
I am getting error on the mentioned line (Problem Line). Since CASE is an expression and does not execute a statement, can anyone help me to get my WHERE Clause working...
Thanks in advance...

HAVING Clause Is A Case Statement???

Mar 15, 2007

i have wrote a query which compares two tables, returning anywhere the qty is not the same in each table:

(simple ex)

Select order_no
from table1
inner join table2
on table1.order_no = table2.order_no
group by order_no
having table1.Qty<> table2.Qty

BUT... I need to add a table3, where there maybe (or may not be enters - thus a left join). If there is an entry in table3 then use qty in table3 and not table1... so having becomes:

CASE WHEN table1.Qty<> table3.Qty
THEN table3.Qty<> table2.Qty
ELSE table1.Qty<> table2.Qty END

but how do i actually write this?

Using CASE Statement In A WHERE Clause

May 16, 2006

Is it possible to use CASE within a WHERE?

I have a query which is something like this, but it returns an error:



SELECT * FROM tablex

WHERE

CASE WHEN 'sexec' IS NOT NULL THEN

dm_marque = 'foo' AND year(dm_date) LIKE 'pyear' AND dm_month LIKE 'pmonth' AND dm_weekno LIKE 'pweek' and dm_sexec LIKE 'sexec' ELSE

dm_marque = 'foo' AND year(dm_date) LIKE 'pyear' AND dm_month LIKE 'pmonth' AND dm_weekno LIKE 'pweek' END

GROUP BY dm_marque



In this case sexec is a form parameter, if something is passed then I need to include it in the where statement, if it isn't I need to include something else. I am using CASE because there are three of these parameters and I want it to stop evaluating as soon as it matches as more than one may match but I only want to apply one.

Many thanks

I am passing in a variable into a CASE statement. Based on the value, I want to return a set of values in an IN clause. Here is an example:

T-SQL (SS2K8) :: Case Statement In The Where Clause?

Jun 5, 2015

I have a population split between two vendors. One gets last names between A and R, the other the rest. Now, on a given date vendor 1 gets everybody.

I can accomplish this with a case statement on the upper range (R or Z), but it seems I should be able to do this without testing at all after the turnover date.

A small bit of the code:

declare @get_date datetime = convert(char(10),getdate(),101)
select top 10 pt.pt_id, pt.last_name
fromsmsmir.mir_acct a join smsmir.mir_pt pt on (a.src_sys_id = pt.src_sys_id
and a.pt_id = pt.pt_id
and a.from_file_ind = pt.from_file_ind

[Code] ....

Seems I should be able to not test the last name after the turnover date, but I can't figure out how.

Conditional Where Clause W/ Case Statement Possible?

Sep 25, 2007

Greetings,

After many hours search many forums and many failed experiments, I figure it's time to turn to the experts.

I need to execute a query that changes the returned data based upon a parameter's value. In my example below, the lob field contains both text values and nulls.


SELECT uniqueID, lob, xdate
FROM mytable
WHERE

CASE WHEN @myparam = 'ALL'

THEN

xdate >= '2007-09-01'
ELSE

xdate >= '2007-09-01' or
lob = @myparm
END

I've experimented with various forms of the LIKE function, checking for null/not null and keep coming up blank.

I thought about using an IF statement and creating different versions of the entire statement, however, in real-life I need to do this with four fields using four parameters (one for each field). The permutations are a little too much.

Any ideas?

Case Statement On Where Clause If Parameter =NULL

Jun 3, 2008

I am working on a Function that takes multiple parameters. I have a query that populates a temporary table, and then it processes some logic. My question is, if the parameter is passed as null, I dont want the query to be affected by this null value. Rather, I would like to not pass it at all to the query. So if the parameter is NULL, dont pass it through the query. I have the following but its not compiling right:


SELECT bom.pEngr_BOM_ID , bom.fEngr_Item_ID, det.pEngr_BOM_Detail_ID, 1, bom.Bill_Type, bom.Rev_Ltr, bom.Series_Ltr
FROM dbo.Engr_BOM_Control bom WITH (nolock)
INNER JOIN dbo.Engr_BOM_Detail det WITH (nolock)
ON det.fEngr_BOM_ID=bom.pEngr_BOM_ID
WHERE bom.pEngr_BOM_ID=@v_pEngr_BOM_ID
AND det.fEngr_BOM_ID=@v_pEngr_BOM_ID
CASE WHEN @v_Bill_Type IS NOT NULL THEN

Using A Field Alias For A CASE Statement In A GROUP BY Clause

May 20, 2004

When I created a CASE statement (This is at work, Pat:)) it is about 30-40 lines long. I gave it a name and set the name = to the case statement:

ie,

SELECT fieldname1 =
CASE
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
ELSE thisandthat
END
, fieldname2
, fieldname3
FROM tablename1
GROUP BY CASE
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
ELSE thisandthat
END, , fieldname2, fieldname3

etc.


The long CASE statement in my GROUP BY is awkward to me. Is this the only way to do it? I tried using the fieldname1 but it comes back as an invalid field name and asks for the "expression".

Regards,

Dave

SQL Server 2012 :: Filtering Query Using CASE Statement Within WHERE Clause

Aug 21, 2014

How I am using a CASE statement within a WHERE clause to filter data:

CREATE PROCEDURE dbo.GetSomeStuff
@filter1 varchar(100) = '',
@filter2 varchar(100) = ''
AS
BEGIN
SELECT

[Code] .

What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.

Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?

I have a table that has for each shop a value that can change over time.For example

BK_POS 1 --> Segment A
BK_POS 1 --> Segment /

What I would like to achieve is to get all distinct Shops (BK_POS) from the table above, but if for that specific pos a row exists where the segment = "/" then I do not want to take this BK_POS in my select query.More concrete, the for example above I do not want to select BK_POS 1 because he has one row where the segment = "/".

Transact SQL :: CASE Statement For A WHERE

Sep 25, 2015

I've been beating my head against this for a bit and haven't been able to figure this out I want to pull 1 set of values between a date time range if @Report = '1' but if @Report = 2 or 3 I want it to drop 3 of the parameters so it will pull all items. by dropping the where parameters for @BeginRangeDate and @LookOutDate and L.COLineStatus. My report works great if I go in and run Report 1 with the date parameters in the where statement and also works great for Reports 2, 3 if I REM out those 3 items in the Where statement. Here is what I currently have

CASE@Report
WHEN'1'THEN
WHEREL.RequestedShipDate>=@BeginRangeDate
ANDL.RequestedShipDate<=@LookoutDate
ANDDO.ForecastDate>=@ForecastDate

[Code] .....
