Dynamic Where Clause With If..else Or Case
Jun 13, 2006
Hello all...
I am trying rewrite an sp that I have that is considered dynamic cause it builds a where clause based on a bunch of if statements then adds it to the the end of select
i.e
if...@where = @where + ' llll '
if...@where = @where + ' llll '
select @statement = @statement + @where
exec(@statement)
I have rewritten most of it to but I have several conditions that use ' contains' for the condition and I can't get SQL server to recognize an if statement or a case statement.
Is it possible to use either statement inside a where clause??
i.e
where if a = 1 then d=e
else contains(.....)
thanks

This is a CASE statement that I am using in the WHERE clause of my query.
SQL Syntax checker keeps returning an error (Incorrect syntax near '=').
Can anyone help me figure out what I need to do to get this to work?
Case When (@Weekday=-1 and @Saturday=0 and @Sunday=0) Then (L1.[Weekday]=-1 AND L2.[Weekday]=-1 AND L3.[Weekday]=-1 AND L4.[Weekday]=-1)
When (@Weekday=0 and @Saturday=-1 and @Sunday=0) Then (L1.Saturday=-1 AND L2.Saturday=-1 AND L3.Saturday=-1 AND L4.Saturday=-1)
When (@Weekday=0 and @Saturday=0 and @Sunday=-1) Then (L1.Sunday=-1 AND L2.Sunday=-1 AND L3.Sunday=-1 AND L4.Sunday=-1)
When (@Weekday=-1 and @Saturday=-1 and @Sunday=-0) Then (L1.Sunday=0 AND L2.Sunday=0 AND L3.Sunday=0 AND L4.Sunday=0)
When (@Weekday=-1 and @Saturday=0 and @Sunday=-1) Then (L1.Saturday=0 AND L2.Saturday=0 AND L3.Saturday=0 AND L4.Saturday=0)
When (@Weekday=0 and @Saturday=-1 and @Sunday=-1) Then (L1.[Weekday]=0 AND L2.[Weekday]=0 AND L3.[Weekday]=0 AND L4.[Weekday]=0)
Else
((L1.[Weekday]=-1 AND L2.[Weekday]=-1 AND L3.[Weekday]=-1 AND L4.[Weekday]=-1) OR
(L1.Saturday=-1 AND L2.Saturday=-1 AND L3.Saturday=-1 AND L4.Saturday=-1) OR
(L1.Sunday=-1 AND L2.Sunday=-1 AND L3.Sunday=-1 AND L4.Sunday=-1))
End

I am stumped trying to use case/if type conditions in having clause. Not sure if it's possible or my syntax or both.
Trying to do something like this:
CASE WHEN (dbo.t_COT_Summary.TCD >= dbo.ReportDate(CONVERT(nvarchar(30), GETDATE(), 101))) THEN
HAVING dbo.t_COT_AP_Exclude.Primary_ID IS NOT NULL
ELSE
HAVING dbo.t_COT_AP_Exclude.Primary_ID IS NULL
END
dbo.t_COT_Summary.TCD = Target Completion Date
dbo.ReportDate = Previous Business Day Function
dbo.t_COT_AP_Exclude.Primary_ID = A left joined ID value I wish to exclude or include in the main query's having.
I hope this makes sense... any suggestions on a better way to do this would be greatly appreciated!

A deveoper just asked me if there is a way to use a case in a where clause. Is this feasible or will we have to do some dynamic sql
where (cr.cb_routine = 1 or cr.cb_urgent = 1 or cr.cb_emergency_room = 1
or cr.cb_on_site_clinic = 1 or cr.cb_retro_request = 1 or cr.cb_initial = 1
or cr.cb_followup = 1 or cr.cb_in_person = 1 or cr.cb_telemed = 1
or cr.df_within is not null or cr.df_provider is not null
or cr.df_proc_test_spec is not null or cr.df_provider_area is not null)
and p.privacy_level = 10
and pe.Location_ID = @Location and
case when @status = 'Pended' then cr.cb_supp_info_need1 = 1
case when @status = 'Criteria for service not met' then cr.cb_criteria_not_1 = 1
case when @status = 'Other' then cr.cb_other_1 = 1
case when @status = 'All' then

Code:
WHERE
weekdayname(weekday(sfa_admin_sbaccount.add_time)) =
case
when "Monday"
then (((SFA_ADMIN_SBACCOUNT.ADD_TIME)>=Date()-3 And (SFA_ADMIN_SBACCOUNT.ADD_TIME)<Date()))
else (((SFA_ADMIN_SBACCOUNT.ADD_TIME)>=Date()-1 And (SFA_ADMIN_SBACCOUNT.ADD_TIME)<Date())));
end
This keeps telling me I'm missing an operator. What I want the query to do is to evaluate the current day's date, then use that to determine whether it needs to set a WHERE clause that goes back 3 days (if it's a Monday) or one day (if it's not a Monday)
This is in Access. Any suggestions?

Dear all...
need your help... i am now trying to create a report using SQL reporting services... when declare all the @parameters needed in where clause, i have come across a problem. where one of the parameters that prompting user to key in...i need to put in some condition.
select..................(blah blah)......
......(SELECT CASE WHEN
((SELECT COUNT(*)
FROM tbl_OutpatientReg OPT
WHERE OPT.PatientID = tbl_Patient.PatientID)) = 1 THEN 0 ELSE 1 END) AS PTType ............................(blah blah).......
where (CONVERT(Varchar(10), tbl_OutpatientReg.VisitDatetime, 103) BETWEEN @FromDate AND @ToDate) OR (@FromDate = ' ') OR (@ToDate = ' ')
AND (@PatientType = CASE WHEN
(SELECT COUNT(*)
FROM tbl_OutpatientReg OPT
WHERE OPT.PatientID = tbl_Patient.PatientID) = 1 THEN 0 ELSE 1 END)
my situition is something like above, i know i have done something wrong in teh WHERE clause for the @PatientType.... can i ask how to restrict the parameters entered by user, let's say if user enter parameter "0", then the visitcount is 1, if enter "1" then the visit count refers to more than 1...
thanks in advanced ...................

i Have the following SQL Statement
Select * from dtree
WHERE Subtype=848 AND
(MODIFYDATE between to_date(%2,'dd/mon/yyyy HH24:MI:SS') AND to_date(%3,'dd/mon/yyyy HH24:MI:SS') )
the numnbers %1, %2, %3 are variables and they get the values from another application. It works so far, but there case I can't handle.If the date values (%2,%3) are empty.I want that my query finds everything without considering the Date condition..I tried it with a CASE condition:
Select * from dtree
WHERE Subtype=848 AND
AND
(MODIFYDATE between to_date(CASE LEN(%2)=0 THEN '03/Feb/2015 00:00:00' END,'dd/mon/yyyy HH24:MI:SS') AND to_date(CASE LEN(%3)=0 THEN '05/Feb/2015 00:00:00' END,'dd/mon/yyyy HH24:MI:SS') )
but it doesn't work. How I can handle empty values?

I am attempting to write a stored procedure that will accept a column name in the form of an nvarchar parameter along with a corresponding value to use to filter the returned results. Obviously I can write a CASE statement with the query repeated for each case with the applicable WHERE clause, but after some research I did find that according to some sites, using the CASE statement in the WHERE clause is perfectly legal. However, I have tried the following code, which is basically a cut & paste version of what I found described, but SQL Server keeps generating errors at the first WHEN clause. I would appreciate anyone's guidance getting this right.
SELECT *
FROM tblTest
WHERE CASE @FilterKey
WHEN 'Description' THEN [Description]=@FilterValue
WHEN 'UpdateTime' THEN [UpdateTime]=@FilterValue
END
In this case, the table [tblTest] has two columns: [Description] and [UpdateTime] and the parameters @FilterKey and @FilterValue would be defined in the sproc definition - or inline with DECLARE/SET statements in Query Analyzer.
Keep in mind that the goal is to NOT have a separate parameter for each property so the (@p is null OR p=@p) method is not appropriate.
Oh, I have also tried to bring the CASE condition inline with the WHEN clause, for instance, WHEN @FilterKey='Description' THEN..., with no change in the results.
Thanks in advance for the feedback.

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...

For Example:SELECT Column1, Column2

WHERE
Column1 = (
SELECT CASE @Test4Nulls
WHEN 1 THEN NULL
ELSE Column1 END) Basically, I want to test for Nulls in a column if my variable @Test4Nulls is True, however, I never get any results back. I believe it is because I am Criteria = NULL instead of Criteria IS NULL, however, I cannot use IS in a case statement How do I test for nulls in a case statement

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

I have my where clause as follows, but it's not working:
WHERE (WPID LIKE @WBS1 + '.' + CASE WHEN @WBS2 = '' THEN substring([Number], 4, 2) = __ ELSE substring([Number], 4, 2) = @WBS2 END CASE)
I give the user two paramters.
The first parameter is to populate the first two characters of a string. There is a "." then another two characters. What I'm trying to do is if the user types nothing in the second parameter, then I use the underscore characters so it can be any two characters. If they do enter two characters, then I want to use them for the 2nd part of the string, hence character 4 and 5.

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

Hi, I need help on this store procedure. I tried to put a case in the where clause. The Gender could be 0, 1 or 2. I want to have the case only when gender is 0 or 1, but not 2. But it gives me error. And if I try to build a dynamic on where query, the I get other error on the temporary table @Users table saying it is not declare. Can anyone help me out? Thanks a lot.
CREATE PROCEDURE dbo.GetUsers
(@UserId uniqueidentifier,
@Gender Int,
@PageNumber Int,
@UsersPerPage Int,
@HowManyUsers INT OUTPUT
)
AS
SET NOCOUNT ON
DECLARE @Users TABLE
(RowNumber Int,
UserId uniqueidentifier,
LastName Varchar(50),
FirstName Varchar(50))
INSERT INTO @Users
SELECT ROW_NUMBER() OVER (ORDER BY P.UserId),
P.UserId, P.LastName, P.FirstName
FROM dbo.Profile P
WHERE P.UserId <> @UserId
CASE WHEN @Gender =1 THEN 'AND P.GenderId = 1'
WHEN @Gender = 0 THEN 'AND P.GenderId = 0'
END
SELECT @HowManyUsers = COUNT(UserId) FROM @Users
SELECT UserId, LastName, FirstName
FROM @Users
WHERE RowNumber > (@PageNumber - 1)*@UsersPerPage
AND RowNumber <= @PageNumber * @UsersPerPage

I need a case-sensitive where clause:
and typ= 'A' collate german_phonebook_cs_as
How can I realize this? The posted code doesn't work.

I am writing a fairly simple sql, and I would like to write something like
Code Snippet
select
firstname as firstname,
case
when firstname = 'Peter' then 'yes'
else
'no'
end as whatever
from
MyTable
where
whatever = 'yes'
And this should then select out the rows where column number 2 is 'yes'.
It doesn't work, and I have to copy the firstname = 'Peter' into the where clause.
But why?

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
