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
CACHE
GO
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;
In oracle, I can setup a sequence generating unique ids and query the next value (which is used as a unique identifer). I know sql server has the identity field but I need to query the next val so I can insert rows into multiple tables.
When a user submits a form, I want to take the dept info from the form (in c# asp.net 2.0) and grab the first two characters. Then query the next val from a table that holds an int.. During insert into two tables it would be something like "IT100" or "SL101". But it needs to be unique.
Is there a way to setup a table in sql server similar to a sequence where I can just query the next val (or some other way?). Remember, I cant do this as identity because I need the key being inserted in other tables during form submit.
It seems very simple but I can't seem to find an answer online that allows me to query the next val in my code then perform the multiple inserts.
Thanks in advance for any assistance you can lend on this,

the subject pretty much says it all, I want to be able to do the following in in VB.net code):
{[If [table with this name] already exists [in this sql database] then [ don't create another one] else [create it and populate it with these values]}
How would I do this?
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 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

[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?

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

CREATE TABLE #Contact (

I was directed to post this here. I am thinking of creating a script that generates another script for creating/dropping tables, indeces, FK, views, stored procedures..etc in the correct sequence in a specific database. I accept the fact this script is dangerous (like if I ran it on production server). But it sure will be very helpful when moving our SQL objects from development to qa and then to production. Is this worth it? Have you see anything that generates such a thing using sys.objects,sys.indexes,sys.foreign_keys etc?
Thanks

I got 5000 rows in source and when i am sending the data to destination it has to create a sequence generator number for each row.

View 2 Replies View RelatedI 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.
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 Scenario is We have Tables like parent and Child Table.
Like we have Child Table as Name AcademyContacts,In that we have Columns like
Guid(PK)Not Null,
AcademyId(FK), Not Null,
Name,Null
WorkPhone,Null
CellPhone,Null
Email Id,Null
Other.Null
Since we have given Null to ''Workphone'',''Cellphone '', ''Email ID''.when inserting the data into these table if the particular columns are empty while inserting also the data will get populate into the table.And I need is if these columns are ''Workphone'',''Cellphone'' , ''Email ID'' they cant insert the data into table.Like it must trigger like ''Please enter atleast one of these ''Workphone'',''Cellphone'' , ''Email ID'' columns.
