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
AND bom.Bill_Type=@v_Bill_Type
END

Hi!I want to make search engine and I have problem with query for this search. User can write username to search or text to search or both. So at first I made query for each event individually: ALTER PROCEDURE [dbo].[Show_Search_Topics]

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...

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?

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

Hi all,
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:
(The where clause will use a field called 'Location')
DECLARE @strTest as Varchar(50)
SET @strTest = 'HI'
SELECT * FROM [SomeTable]
WHERE
CASE @strTest
WHEN 'HI' THEN Location IN('1', '2', '3')
END
ORDER BY Location
Is this possible to do?

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.

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?

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.
Â
Update XYZ Set AB = a.Amt * (CASE WHEN c.Type = 'ABC'Â THENÂ (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.

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".

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!

The script is not as simple as this or else I would just check for NULL values. I really need to switch NULL values to something I can pass on to a variable and query on it from Reporting Services.

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?

23 Â Â Â B Â Â Â 50
5 Â Â Â Â B Â Â Â 560
I want to filter the store in "where clause" Â 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]= Â (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.

I'm writing some generalized stored procedures for use form managed code. The following stored proc works great:
CREATE PROCEDURE fnd_Send (
@Message VARCHAR(5000),
@Contract SYSNAME,
@MessageType SYSNAME,
@FromService SYSNAME,
@ToService VARCHAR(100),
@Encrypted Bit
)
AS
BEGIN
DECLARE @Handle UNIQUEIDENTIFIER;
BEGIN DIALOG CONVERSATION @Handle
FROM SERVICE @FromService
TO SERVICE @ToService
ON CONTRACT @Contract
WITH ENCRYPTION = OFF;
SEND ON CONVERSATION @Handle
MESSAGE TYPE @MessageType(@Message);
Notice the use of SYSNAME parameters €“ translating the parameter into an object name - allows it to work in the BEGIN DIALOG statement when an system object is needed. Works create and cues up generic messages.
The following will not compile:
CREATE PROCEDURE fnd_Receive (
@Queue SYSNAME,
@Message VARCHAR(5000) out,
@MessageType SYSNAME out
)
AS
BEGIN
DECLARE @Handle UNIQUEIDENTIFIER;
RECEIVE TOP (1)
@Handle = conversation_handle,
@MessageType = message_type_name,
@Message = message_body
FROM @Queue;
END
GO
It won€™t let me use the SYSNAME field @Queue in the FROM clause. I€™m getting an unfriendly:
Msg 102, Level 15, State 1, Procedure fnd_Receive, Line 15
Incorrect syntax near '@Queue'.
It looks like maybe I can€™t bind a variable in the FROM clause €“ perhaps like you cannot in a SELECT statement. I can fall back to dynamic SQL in the stored proc or in the managed code; I was hoping not to.
Can anyone shed any light on this? Also, are there any other techniques I'm missing to avoid falling back to a dynamic SQL statement.
Thank you in advance -

shipment_status =
CASE

WHEN [logic for condition 4]

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

I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
Key cannot be null. Parameter name: key
