SQL Server 2012 :: Finding Break In Sequence
Feb 21, 2014
I need to be able to identify breaks in a sequence so I can evaluate the data more correctly. In the sample I have given I need to be able to identify the break in sequence at 69397576, ideally I would set that as a D. My query also needs to recognize that the 3 sequences following 69397576 are sequential and would belong to that set. so the out come would look like this.
id file_name page_follow
693975631555557564_22222221114014810D
693975641555557564_22222221114014810F

Hi,
We're currently developing an application against SQL Server 2005 Standard Edition. Recently, we've started to consider deploying certain installations against SQL Server Express. We're particularly worried about some stored procedures we've written taking advantages of features which will not be available in SQL Server Express, is there a simple compliance tool or such that we can scan our existing tables/functions/stored procedures/etc with to identify potential pitfalls when running on SQL Server Express?
Thanks,
Jeremy

I have SQL Server 2012, and I'm trying to execute a bcp with a queryout and it is not working with line break, I will send you an example of a simple query my real case is a very long query that contains line breaks but this example behaves the same:
DECLARE @StoredProcedure AS NVARCHAR(4000) ,
@sql AS NVARCHAR(4000)
SET @StoredProcedure = N'"SELECT *
from clarity.[dbo].[ACCESS_DEP]"'
[code]...
Of course that is not the solution as I have a very long query that requires line breaks.

I've started using a SEQUENCE in a table instead of an identity.
I seem to be experiencing problems of the sequence getting reset to a lower value periodically. Inserting will work on the table, producing the next bigint in the sequence as the primary key, for days and then all of the sudden duplicate primary key errors show up. When I check, the last primary key value in the table is higher than the current value of the sequence.
For example: right now I have primary key values 6000 through 7032 contiguously in the table, all of which were generated with the sequence. Suddenly I'm getting duplicate primary key errors. A quick check of the sequence shows it's at 7002, but the last inserted row has a primary key of 7032!
I'm populating this table in one place (in the application layer), leaving the primary key null, which allows the default constraint to get the next sequence.
When the problem shows up, I've reset the sequence to the higher number in the past and all is well for many days, then the problem occurs again.
The definition for the sequence is:
CREATE SEQUENCE [dbo].[IntegrationQueueSEQ]
AS [bigint]
START WITH 1
INCREMENT BY 1
MINVALUE 0
MAXVALUE 9223372036854775807
CYCLE
CACHE 50
The default constraint for the primary key on the table is defined as:
ALTER TABLE [dbo].[IntegrationQueue] ADD CONSTRAINT [DF_IntegrationQueue_IntegrationQueueID] DEFAULT (NEXT VALUE FOR [dbo].[IntegrationQueueSEQ]) FOR [IntegrationQueueID]

I'm looking to see if there is a way to populate starting number for the sequence from a max value of a table.
CREATE SEQUENCE test_seq
AS [int]
START WITH (select max(col1)+1000 from table1)
INCREMENT BY 1
MINVALUE 1
MAXVALUE 2147483647

Create Table Sample (ID int not null primary key, RefID int , SeqNo int , Name varchar(10) )
insert into Sample
select 1, 1000, 1, 'Mike'
union
select 2, 1000, 2, 'Mikey'
union
select 3, 1000, 3, 'Michel'
union
select 4, 1001, 1, 'Carmel'
union
[code]....
select * from SampleI have here sample data given. What I want to do is, I want to check the RefID which is not having proper order of sequence number. If you see the RefID 1000, 1001 they are having properly sequence order in SeqNo field. But it is not in RefID 1002. RefID 1002 does not have proper order. It is because user has deleted a row which was having seqno 2. So i want to get what are all the RefID's are not having properly sequenced. So that I would be able to know these are all the RefID's are affected by delete statement that was done by user.

We are running SQL Server 2012 on Windows Server 2008. Just wondering what type of actions would break the backup-chain or backup sequence? For instance, if you have tlog backups being taken every 10 minutes and you stop the SQL Server Service for say 30 minutes. Would this action break the backup chain? Or would everything return to normal once the SQL Server Service is restarted?

Write the query that produces the below results. I'm not ale to join the two sets in a way so that it displays NULLs if no purchase was made on a given day for a particular product. I need NULLs or s so that it shows up correctly on my SSRS report.
-- declare @from DATE='2015-1-5',@to DATE='2015-1-10'

I have a Contact table where I enter a "Parent" (Mother or Father) with IsSubscriber = 1. I also enter all of their children in this same table, with IsDependent = 1.
I then have a Relationship table that relates each child to the appropriate parent record in the Contact table.
I need to assign a sequence number to each child ONLY if they were a multiple birth (twins, triplets, etc.; all have the same DOB). I've been successful at writing a query using ROW_NUMBER(), but it includes the single births (no other child of the same parent has the same DOB).
Stripped down version of Tables and Data and my failed attempt to write a query to do what I want:
IF OBJECT_ID('TempDB..#Contact','U') IS NOT NULL
DROP TABLE #Contact
CREATE TABLE #Contact (
ContactId INT IDENTITY(1,1) PRIMARY KEY CLUSTERED
, IsSubscriber BIT
[Code] ....
This is as close as I can seem to get.

The following is sample data I am dealing with.
SELECT * INTO TEMP
FROM
(SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '01-01-2014' AS STARTDATE, '01-31-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '02-01-2014' AS STARTDATE, '02-28-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '03-01-2014' AS STARTDATE, '03-31-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A2000' AS CODE, '04-01-2014' AS STARTDATE, '04-30-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '05-01-2014' AS STARTDATE, '05-31-2014' AS ENDDATE) X
I need to extract the date that the value in CODE column changes to another code for each value of CATEGORY and if there is no change, to record the original CODE value and its startdate for each CATEGORY.

I'm trying to come up with a query for this data:
CREATE TABLE #Visits (OpportunityID int, ActivityID int, FirstVisit date, ScheduledEnd datetime, isFirstVisit bit, isRepeatVisit bit)
INSERT #Visits (OpportunityID, ActivityID, FirstVisit, ScheduledEnd)
SELECT 1, 1001, '2014-08-17', '2014-08-17 12:00:00.000' UNION ALL
SELECT 1, 1002, '2014-08-17', '2014-08-17 17:04:13.000' UNION ALL
SELECT 2, 1003, '2014-08-18', '2014-08-18 20:39:56.000' UNION ALL
[Code] ....
Here are the expected results:
OpportunityIDActivityIDFirstVisitScheduledEndisFirstVisitisRepeatVisit
110012014-08-172014-08-17 12:00:00.00010
110022014-08-172014-08-17 17:04:13.00001
210032014-08-182014-08-18 20:39:56.00001
210042014-08-182014-08-18 18:00:00.00010
[Code] ....
Basically I'd like to mark the first Activity for each OpportunityID as a First Visit if its ScheduledEnd falls on the same day as the FirstVisit, and otherwise mark it as a Repeat Visit.
I have this so far, but it doesn't pick up on that the ScheduledEnd needs to be on the same day as the FirstVisit date to count as a first visit:
SELECT*,
CASE MIN(ScheduledEnd) OVER (PARTITION BY FirstVisit)
WHEN ScheduledEnd THEN 1
ELSE 0
END AS isFirstVisit,
CASE MIN(ScheduledEnd) OVER (PARTITION BY FirstVisit)
WHEN ScheduledEnd THEN 0
ELSE 1
END AS isRepeatVisit
FROM#Visits

How do you find stale stored procedures ?
In a scenario where a developer created a slight modification of a stored procedure because he was afraid of breaking something else and took the easy way out, and a few more later down the line, multiple versions of a stored proc. doing slightly different things are just laying around.
"Last used" would be useful piece of information to determine the most recent date a stored procedure was called, either by the application itself or by another stored procedure itself called by the application.
Any stored proc not used for more than say 6 months would then be identified as a candidate for clean-up.
So - short or creating - after the fact - a trigger to update the usage date upon each call - which means a lot of work and no result for the next six months, how can one go about this ?
And could this be done in SS2K8 ?

I am trying to build a select statement that will
1). find records where a duplicate field exists.
2.) show the ItemNo of records where the Historical data is ' '.
I have the query which shows me the duplicates but I'm stuck when trying to only show records where the Historical field = ' '.
Originally I thought I could accomplish this goal with a sub query based off of the original duplicate result set but SQL server returns an error.
Below you will find a temp table to create and try in your environment.
create table #Items
(
ItemNovarchar (50),
SearchNo varchar (50),
Historical int
[Code] ....
Ultimately I need a result set that returns 'ATMR10 MFZ N', and 'QBGFEP2050 CH DIS'.

I've got a fairly large hierarchy table and I'm trying to put together a query to find the lowest level descendants of the hierarchy. I think there must be some way to use the "Breadth-first" approach that's stated in the MSDN technet sites about SQL Server HierarchyID but i'm not sure how to write the necessary T-SQL to traverse that. I know I can get all the descendants of a parent node like this
SELECT *
FROM AdventureWorks2012.HumanResources.Employee
WHERE OrganizationNode.IsDescendantOf(@ParentNode) = 1
However, this query returns all levels for that parent's branch. If I just wanted list of employees that were at the lowest level of the branch(es) for this parent node, how would I do this?

There are many duplicate records on my data table because users constantly register under two accounts. I have a query that identify the records that have a duplicate, but it only shows one of the two records, and I need to show the two records so that I can reconcile the differences.The query is taken from a post on stack overflow. It gives me 196, but I need to see the 392 records.
How to identify the duplicates and show the tow records without having to hard code any values, so I can use the query in a report, and anytime there are new duplicates, the report shows them.
SELECT
[groom_first_name]
,[groom_last_name]
,[bride_first_name]
,[bride_last_name]

We are facing problem in doing page break with column grouping. Our column group contains years e.g 2011, 2013 . We want to show a complete page for a year.
Suppose 2011 has 10 records(horizontal) and 2013 has 12 records(horizontal) in column. The output should be 10 records of 2011 in first page, 12 records of 2013 in second page.
We cannot change the report layout to make column to row and vice versa.

I have two databases with different collation sequences, let them be called A (SQL_Latin1_General_CI_AS) and B (Latin1_General_CI_AS). Now I need to join between the two (including through temp tables with server collation being Latin1_General_CI_AS). In order to get rid of the errors when trying to do so I changed all my statements in the WHERE and ON clauses to
A.table.column collate database_default = B.table.column
If I were to change the collation of the character typed columns in database A to the one in database B, would it make any difference in terms of performance, or would it just be a useless exercise? Just asking because many of those columns are part of a primary or foreign key that would need to first be dropped and then recreated after changing the collation, and I'd prefer to save myself the effort of writing scripts to do so if the answer is NO.
BTW, I tried to change the database's collation sequence, but that leaves the collation of the columns unchanged.

We have some URLs within a bulk block of text some of which are very long. I need to identify rows where such urls exceed say 100 characters in length in amongst other text.So the rule would be return a record if within the string there is a string (without spaces) longer than 100 characters.

If Exists ( Select c.name from sys.columns c where object_id = object_id('HH835HP') and C.name = 'ID_1' )
Begin
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;
End;
Obviously... The stuff inside the IF is wrong syntax...I mean
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;

The following works just fine. The table tmpMHPCLMDET does have a column ADMTDT ( varchar(8) ).
While I am adding the sequence of numbers I like it to be sorted based on ADMTDT column.
What that means is the row with the earliest ( smallest ) ADMTDT will get 1 and the next 2 and so on.
Declare @ID int
If Exists ( Select c.name from sys.columns c where object_id = object_id('tmpMHPCLMDET') and C.name = 'ServiceLineID' )
Begin
--Adding a sequence of numbers to the ServiceLineID column.
SET @id = 0
UPDATE tmpMHPCLMDET
SET @id = ServiceLineID = @id + 1;
End;

I have a report with several matrix objects. The data contained in each matrix is simple. One matrix has one column of labels and a column of data. The other has 3 columns of data. Both matrix's only show about 25 rows of data. A variable amount of data is displayed above the matrix's so that sometime the render across a page boundary. Whenever this happens the matrix doesn't render rows down to the bottom of the page. A considerable amount of empty space is left on the page, the completed matrix is displayed on the next page. I'm wondering how to get the matrix to render in this empty space.
This problem only occurs when I view the report on screen, in the Visual Studio "Preview" window, or from the Report Server web site. Tiff, pdf and printed output doesn't contain the extra space.
I've tried adding my matrix to a List and a Rectangle to see of this would fix the problem but it didn't help.
I've check the dimensions and margins or the page and I don't think I have any sizing problems, everything should fit on the page.
