Transact SQL :: Using Isnull In Where Condition

Jul 10, 2015

I am in assumption that we cannot do NULL value comparison in where clause directly (results will not be proper) we have to use ISNULL. Is my understanding correct? Is using ISNULL efficient when we have to this operation for large volume?

Why Does The Condition Activated = Isnull(@activated, -1) Work?

Jul 16, 2005

I have a stored procedure into which a bit type of parameter called '@activated' is being passed. This stored procedure gets all the users matching the condition :
Activated = isnull(@activated, -1)

In users table, one of the columns is 'Activated' of bit type.
The strange thing happening here is that if @activated is null, then the above condition is true for all rows in users table, even though we know that the column Activation  is either 1 or 0 only and never -1.Can someone explain why this strange thing is happening?

Transact SQL :: Select Column On Condition

Jul 4, 2015

I have a table called names  (firstname, lastname, number) then i have a DECLARED variable called  @displaynum...If @displaynum id true   my select query should select the number column.  if the variable is false , only the first two columns are selected.

e.g   @displaynum = true                                          
@displaynum = false
Firstname  | Lastname | number                               Firstname  | Lastnam

blah           |   blah        |   12345                             
blah           |  blah

i am not sure if this is possible as a case still selects the column but just changes the values.

Transact SQL :: Get Records Based On Condition In Server

Nov 22, 2015

I have a question about SQL Server.

Table patient:

create table patient (pn int,code int,date date,doctorcode int)
insert into patient (pn,code,date,doctorcode)
values
(1,10,'2015-02-19','100),
(1,10,'2015-02-19','101),
(1,10,'2015-02-19','102),

[Code] ...

Table Patientref:

create table patientref
(pn int,code int, sdate date,edate date,status int)
insert into patientref(pn,code,sdate,edate,status)
values
(1,10,'2015-02-13','2015-02-19',1),
(1,10,'2015-02-19','2015-03-24',2),

[Code] ...

Here we need consider patient dates that fall between sdate and edate of the patientrefs table, and then we need to consider the highest status values in order (for example, the highest values in order - 2 is first highest, 4 is second highest, 3 is third highest, and 1 is fourth highest value)

If the date falls between multiple different sdate and edate with the same status values, then we need to consider the latest sdate value and from that entire record we need to extract that value.

Examples: patient

pn |  code  |  date      |   doctorcode
2  |  10    |2015-02-12  |   101
2  |  10    |2015-02-13  |   102
2  |  10    |2015-02-14  |   103

Table : Patientref:

pn |  code  |  sdate      |   edate      | Status
2  |  10    |2015-02-08   |   2015-02-19 |  4
2  |  10    |2015-02-09   |   2015-02-19 |  2
2  |  10    |2015-02-10   |   2015-02-19 |  2
2  |  10    |2015-02-11   |   2015-02-18 |  1

Here, pn=2 values have dates which fall between sdate and edate of patientref table. Then we give highest values status is 2, and status 2 values have two records, then we go for max sdate(latest sdate). Then this pn=2 latest sdates is 2015-02-10 and we need to retrieve the corresponding edate and status values.

pn = 4donot have sdate and edate and status values dut not fall conditon 

Based on this, the desired output is below:

pn |  code  |  date      |   doctorcode | sdate     |edate      |status
1  |  10    |2015-02-19  |   100        |2015-02-19 |2015-03-24 | 2
1  |  10    |2015-02-19  |   101        |2015-02-19 |2015-03-24 | 2
1  |  10    |2015-02-19  |   102        |2015-02-19 |2015-03-24 | 2
2  |  10    |2015-02-12  |   101        |2015-02-10 |2015-02-19 | 2

[Code] ...

I tried it like this:

select p.pn,p.code,p.[date],p.doctorcode,pr.sdate,pr.edate,pr.[status] from patient p
 outer apply (select top 1 pr.pn,pr.code,pr.sdate,pr.edate,pr.[status] from patientref pr 
where pr.pn=p.pn and pr.code=p.code and p.date between pr.sdate and pr.edate
 order by case when pr.status=2 
then 1 when pr.status=4 then 2
 when pr.status=3 then 3 
when pr.status=1 then 4 end ,pr.sdate 
 )pr

but this query not given expected result.here when dos not fall between sdate and edate  that records not given in the above query. I required that records also.if not fall b/w condition then we need retrive that records empty values for that records.

Transact SQL :: How To GROUP BY And Get Aggregate Where A Certain Condition Is True

Jul 16, 2015

I am using SQL 2005.  I have some data from an old application that did not follow the rules for normalization.  The table is for Invoices, and the table allows for 13 purchase items per record.  So in each row of my table I have a non-unique integer field itemID, itemID1, itemID2 ... itemID12.  For each itemID I also have "lbs_total" and "line_total" (which is price * lbs_total) - so itemID, lbs_total, line_total ... itemID1, lbs_total1, line_total1 ... etc.  It's a mess, I know.Each row has a unique Customer Number ("cno") and an Invoice Date ("inv_date").  My proc needs to allow for params for the item number, and a start date and end date for BETWEEN on the inv_date.I also need to get the aggregate for the lbs_total and the line_total.

Transact SQL :: Selecting First Row After Date Matching Condition?

Sep 22, 2015

I've two audit tables, AUDIT_ORDERS and AUDIT_ORDER_LINES.

The AUDIT_ORDERS has these columns: AUDIT_ID, ORDER_ID, AUDIT_DATE and other ones.

The AUDIT_ORDER_LINES has these columns: AUDIT_ID, ORDER_ID, ORDER_LINE_ID, AUDIT_DATE and other ones.

I need to join these two tables in order to select for each order line row the first order having the related audit date lower than or equal to the audit date of the related order line.

I don't want to use the TOP 1 clause or a subquery. I think to complete a such statement:

SELECT OL.Order_Line_ID, O.Order_ID, OL.Audit_Date, O.Audit_Date
FROM AUDIT_ORDER_LINES as OL INNER JOIN AUDIT_ORDERS as O
on OL.Order_ID = O.Order_ID and O.Audit_Date <= OL.Audit_Date ...

I'd like to get the first row of the Audit_Orders with audit_date <= of the audit_date of the Audit_Order_Lines table by using the join clause.

Transact SQL :: While Loop Does Not End When Condition Is No Longer True

Dec 1, 2015

I have a Stored Procedure, wherein I need to use a while loop. essentially the loop looks like this.

Set @Kount = 1
--TestScript
Select 'TempReqTable', * from @TempReq
WHILE Exists(Select * from @TempReq WHERE TempID = @Kount)
BEGIN
--Do stuff with values from table
Set @Kount += 1
END

The test script confirms that there is only one row in the @TempReq table.  However the loop never stops running and @Kount keeps being incremented and incremented until I manually stop the execution of the SP.

Is there some rule that I am not aware of that does not allow the use of an Exists statement in the condition of a While loop?

Transact SQL :: Exclude A Distinct Records From Select When One Condition Is True?

I have products name Gin (Pid=1), Scotch (Pid=2) and Vodka (Pid=3) in a table products.

Pid

And I have a table that holds purchase called Customer_Purchases that contain the following records:

Cid
Pid

1
2
2
1
2
3
3
2

I would like to make a marketing list for all customers that purchased Gin or Scotch but exclude customers that purchased Vodka. The result I am looking for would return only 2 records: Cid’s 1 (Alex) and 3 (Carrie) but not 2 (because Bob bought Vodka).

I know how to make a SELECT DISTINCT statement but as soon as I include Pid=2 This clearly doesn’t work :

SELECT DISTINCT Pid, Cid
FROM           
Customer_Purchases
WHERE        (Cid = 1) OR
(Cid = 3) OR

Transact SQL :: Limit A Query Results When All Of Line Items Under Group Meet Certain Condition

Oct 1, 2015

I have a query that returns the data about test cases.  Each test case can have multiple bugs associated to it.  I would like a query that only returns the test cases that have all their associated bugs status = closed.For instance here is a sample of my data

TestCaseID TestCaseDescription  BugID BugStatus
1                TestCase1                       1      Closed
2                TestCase1                       2      Open
3                TestCase2                      11     Closed
4                TestCase2                      12     Closed
5                TestCase2                      13     Closed

How can I limit this to only return TestCase2 data since all of that test case's bugs have a status of closed.

COndition Spli - Error Date Condition

Apr 19, 2007

Dear friends,

I'm having a problem... maybe it's very simple, but with soo many work, right now I can't think well...



I need to filter rows in a dataflow...

I created a condition spli to that... maybe there is a better solution...

And the condition is: Datex != NULL(DT_DATE)

(Some DATE != NULL)





[Eliminar Datex NULL [17090]] Error: The expression "Datex != NULL(DT_DATE)" on "output "Case 1" (17123)" evaluated to NULL, but the "component "Eliminar Datex NULL" (17090)" requires a Boolean results. Modify the error row disposition on the output to treat this result as False (Ignore Failure) or to redirect this row to the error output (Redirect Row). The expression results must be Boolean for a Conditional Split. A NULL expression result is an error.



What is wrong??

Regards,

Pedro

Unfortunately, it only returns exact matches, as if it were written as "where lname = ISNULL(@lname, lname)"
