Returning An IN Clause From A CASE Statement

Using Case Statement With WHERE Clause...
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...

If/Case Statement In Having/Where Clause - Please Help Me.
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]

HAVING Clause Is 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?

Using CASE Statement In A WHERE Clause
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

Karen

Conditional Where Clause W/ Case Statement Possible?
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?
 
Rob

Case Statement On Where Clause If Parameter =NULL
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

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

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

Support For RETURNING Clause
I am into migrating some Oracle DML queries to SQL Server. The DML statements has RETURNING clause in them. For example :

insert into test select col1,col2 from table2 RETURNING col1 INTO variable

Here the RETURNING clause is used to get the data in the rows affected by the DML statement.

Is there a way to achieve this in SQL Server ?

Problem Using Result From CASE In Another CASE Statement
I 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

Using Case In Having Clause
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!

CASE WHERE Clause Help
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?

Using CASE In The WHERE Clause
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.

Using Case In Where Clause With Nulls
For Example:SELECT Column1, Column2
FROM Table
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

CASE WHEN Equivalent In WHERE Clause?
Is there an equivalant construction to the CASE WHEN statement thatcan be used in the WHERE clause?For example, this works:SELECTFirstName = CASE WHEN c.FirstName = 'Bob' THEN'Robert'ELSEc.FirstNameEND,c.LastNameFROMContacts cWHERE(c.FirstName = 'Bob')OR(c.FirstName = 'Robert')But is there a way to build somehting resembling this (without usingExec-SQL)@FirstName nvarchar(35)SELECTc.FirstNamec.LastNameFROMContacts cWHERECASE WHEN @FirstName = 'Bob' THENc.BlueHair = 1ELSE CASE WHEN @FirstName = 'Frank' THENc.PastaEater = 1ELSEc.HatSize 5END END

Variables In A WHERE CASE Clause
I am using an INSERT statement which looks at a particular variable to determine data to place in a temp table, and am using the following format:

INSERT INTO #tblname
SELECT
column1, 2, etc.
FROM tblname2
WHERE parameter CASE @InputParm
WHEN 'xx' THEN 'xx'
WHEN 'yy' THEN 'yy'
ELSE (use both 'xx' AND 'yy')

In other words, I'd like it to look at the @InputParm, see if it's ONLY 'xx' or ONLY 'yy' and then use those appropriately, but if it's anything else, use BOTH 'xx' and 'yy'. I have to avoid using the EXEC(str) setup because this is a part of nested loops, and the table MUST exist beyond the loop execution.

I know this is possible (according to the MS site), but I can't get the syntax to work. Any assistance would be greatly appreciated.

With thanks,

Dynamic Where Clause With If..else Or Case
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

Where Clause To Use Case W/ Parameters
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.

Why Can't I Use Columns Based On Case Down In My Where Clause
 

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?

Case Statement Error In An Insert Statement
Hi 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.

SQLRowCount() Returning -1 When Used With SELECT Statement.
Hi friends,
I am facing problem with SQLRowCount() function which is returning -1 when I tried to fetch records greater than 99 from my data file. if the data file contains total of 99 records then the above function is returning its second parameter value nRowCount as 99 but if dat file contains 100 records then it is returning nRowCount as -1
Please tell me whether it is a driver specic error or some thing else. I am using a ODBC driver for a database called MYOB.

Below is the piece of code that I used for fetching records.


if (SQLExecDirect(m_StmtHandle, (PUCHAR)sExecuteStatement.c_str(), SQL_NTS) != SQL_SUCCESS) return false;

if (SQLNumResultCols(m_StmtHandle,(SQLSMALLINT *) &nColumnCount) != SQL_SUCCESS) return false;

if (SQLRowCount(m_StmtHandle,&nRowCount) != SQL_SUCCESS) return false;

The string 'sExecuteStatement' in SQLExecDirect() function above is carrying a Select query.

Its an unpredictable error because the function fails to return exact row count for 100 records, but it is working fine with 99 records.

I am not using any kind of array with size of 99 or 100 in my code.

What I want to know is:
1. Can I use SQLRowCount() with SELECT statement, If not what is the alternative.
2. Is this a driver specific error?.
3. Can I use SQL_DIAG_ROW_COUNT instead of SQLRowCount? If Yes, How to use it?.

Your help will be greatly appriciated if you give me a piece of code for this issue.

Troubles Returning Values With SQL Statement -
Hi, I just want to know the following.

Is it posible to write a SQL statement that searches all values in a table where the

e.g:

"Jobid = 1" and sort the result set according to the "CategoryID"?

then if you want to display the values, you can populate them according to the "CategoryID"?

 

and then also write the result set to a "text file", and catagorize everything  according to the "categoryID" in the following format???

 

Category Number: 8                   Description: Site

  Date             Labour                     Hours                   Rate                 Subtotal

10/05/2005   Artisan                      20                        95.00                1,900.00
10/06/2005   Labourer                   7                           45                       315.00

       
                                                                                     Category Total 2,215.00
