Return values not seen in previous records
I'd like to be able to return Code values below that have not occurred previously (ordered by ID). I have a feeling it's going to involve a ROW_NUMBER() and CTE, but I can't quite put my finger on it. See the example below.
DROP TABLE #codes CREATE TABLE #codes (ID INT NOT NULL, Code VARCHAR(20) NOT NULL) ALTER TABLE #codes ADD CONSTRAINT pk_codes PRIMARY KEY (ID, Code) INSERT INTO #codes (ID, Code) VALUES (1, 'A'), (1, 'B'), (1, 'C'), (1, 'D'), (1, 'F'), (2, 'A'), (2, 'B'), (2, 'C'), (2, 'D'), (2, 'E'),-- not seen in #1 - return this record (3, 'B'), (3, 'C'), (3, 'D'), (3, 'E'), (3, 'F'),-- not seen in #2 but was seen in #1 so no need to return this record (3, 'G') -- not seen in #1 or #2 - return this record SELECT * FROM #codes ORDER BY ID, Code
I need a query to return (2, 'E') and (3, 'G') because they did not occur in ID's prior to them. Hope this makes sense. Any help?
Thanks!

Distinct Cummulative count
I need to calculate the distinct Cummulative count for the incremental months
As shown below
Month PersonName
7 sam
7 kim
7 tim
8 sam
8 tom
8 rex
8 ram
9 sam
10 Rob
o/p :
Month CountPerMonth DistinctCummulativeCount
7 3 3
8 4 6
9 1 6
10 1 7
CountPerMonth=count for respective month
DistinctCummulativeCount=column should give distinct count for the months in (7),(7,8),(7,8,9), (7,8,9,10) respectively.
Appreciate your help..
Thanks.

Syntax error declaring variables within trigger
I'm writing a trigger that when a new record is added to one database (basically a new customer being added), it then adds some of those details to a second database which is used by another internal system.
I've come up with the following code :
create trigger NewEntity
on [Intranet-Test].[dbo].[vpw_Entities]
after insert
as
declare @type_id int
declare @entity_id int
declare @Is_Active bit
declare @Entity_Name nvarchar(256)
@Is_Active=inserted.IsActive
@entity_id=inserted.EntityID
@Entity_Name=inserted.EntityName
@type_id=inserted.TypeID
if @type_id in ('2','3')
begin
insert into [TimeTracking-Test].[dbo].[clients] (clientid, active, clientname)
values (@entity_id, CAST(@Is_Active as INT), @Entity_Name)
end
gobut within SSMS it's indicating a syntax error near the "@Is_Active=inserted.IsActive" line, which appears to be related to the declare statements (eg if I add anything between them the new line gets the syntax error).
Looking online I can't find any indication of why I'd be getting this error, though I'm assuming that variable declaration is actually allowed within a trigger.
Anyone know why this isn't working? If it is the declare statements at fault, do you have any ideas how to achieve the same thing without them? I tried putting the inserted.entityname etc references directly into the values part of the insert statement but that also gave me an error.

Hi all,
I've heard that you should not store dates ie "02/02/2014" as strings and they should be stored as datetime.

Update one table based on condition from another table using date ranges
Hello!
I have two tables:
DateRange (consists of ranges of dates):
StartDate FinishDate Condition
2014-01-02 2014-01-03 true
2014-01-03 2014-01-13 false
2014-01-13 2014-01-14 true
Calendar (consists of three-year dates):
CalendarDate IsParental

2014-01-07
2014-01-08
2014-01-09
2014-01-10
...
I want to update table Calendar by setting IsParental=1 for those dates that are contained in table DateRange betweenStartDate and FinishDate AND Condition IS TRUE.
The query without loop should look similar to this but it works wrong:
UPDATECalendar
SET IsParental = 1
WHERECalendarDate BETWEEN(SELECTStartDate
FROM DateRange
WHERE Calendar. CalendarDate = DateRange. StartDate)
AND (SELECT StartDate
FROM DateRange
WHERE Calendar. CalendarDate = DateRange. FinishDate )
ANDCondition IS TRUE
;
Is it possible to do without loop? Thank you for help!

Partitioning Advice on PRIMARY FILE GROUP
Hi,
I wonder if you can help. I would like some advice on partitioning within the PRIMARY file group. Basically I have a lot of experience on partitioning and in the past I have followed best practice is documents such asPartitioned Table and Index Strategies Using SQL Server 2008 and the Analysis Services Performance Guide so in summary when partitioning in the past I have followed best practice, e.g. have one file group per partition and have your partition key as a component within the primary key of the table you are partitioning.
However following best practice in this way can require a lot of maintainence, and the system I am performance tuning at the moment has a limited life span.
So in this context I wonder if there are any advantages of basing partitioning on a PRIMARY file group?
Kind Regards,
Kieran.

Left Outer Join on same table clarification
HI,
I have a table that gets populated from 3<sup>rd</sup> party system. We don’t have control over it. So, the table has master record (master) and children. Master type is 78 and children’s type is 64. So, it looks like this. In the 3<sup>rd</sup> party system, if Master transaction gets cancelled, it is recorded as type 178. If child is cancelled, then it is 164. Once the child is cancelled and created again using one process then newly created transaction will have 65 as type. Same thing with Master cancelled transaction also. It will be 79. So, to summarize:
Master:
Brand New Transaction type = 78
Cancelled Transaction type = 178
Cancelled with creation transaction type = 79
Child:
Brand New Transaction type = 64
Cancelled Transaction type = 164
Cancelled with creation transaction type = 65
I don’t have to bother about master records. I need to focus on only children for my query.
ID | TxnID | Master | Type | TDate | Location |
193075 | 211554 | 211543 | 64 | 20140805 | ABC |

I need a clarification regarding left Outer Join.
In the first left outer join query both 64 and 164 both have TL.TxnID populated. Why is that?. What I understand from
left outer join is that ‘Returns all the rows’ from left table and only matching data from right table.
Here, matching row from right table is 211565 and 164 record (id 193083). So, only it should have TxnID populated. But row 211565 and 64 has TL.txnID getting populated (ID 193082).
Why is it? Am I not understanding left out join properly?
Thanks,

How to check if a file exists in a directory?
Sorry to bother everyone with something so simple. I installed and ran the function from here.
http://www.tech-recipes.com/rx/30527/sql-server-how-to-check-if-a-file-exists-in-a-directory/
Just like in that example, I'm running this.
select dbo.fc_FileExists('C:\Users\Ryan\Desktop\Briefcase\Best Coffee Bars in NYC.doc');
I'm getting a o0, but I know it should be 1. Maybe there is a security or permission issue here. I'm not sure. I know one thing for sure, that the file is in that place!!
What am I missing? What could I be doing wrong here?
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.
