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
What I am wanting to do in another column is keep track of the sequence number for each distinct invoice like:
SeqNo 1 2 3 1 2 1
I am working in a stored proc and i cant get past adding the numbers up at each line as a whole and not reseting when the next invoice number is present. Any help would be so greatly appreciated.
I have a procedure which updates a sequence number in a table such as the one below.
Seq Sequence_Id
------ ------------------ NextNum 1
This is the procedure ...
create procedure DBO.MIG_SYS_NEXTVAL(@sequence varchar(10), @sequence_id int) as begin
update mig_sys_sequences set @sequence_id = sequence_id = sequence_id + 1 where seq = 'CSN'
return(@sequence_id) end
The purpose of this is to generate a sequential number each time the procedure is called. This number would then be used in a number of different tables to allocate a unique id so that the id is unique across the different tables.
1). What is the most efficient way of allocating these unique ids? The tables that I plan to update will already be populated with data.
2). How would I call the above procedure from an UPDATE statement?
I have a table which has two column like following table and I don't know how can I update theses two column with identity numbers but just the fields which are equal 111.
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 question in SQL server. For example I have a table which has two column like following table and I don't know how can I update theses two column with identity numbers but just the fields which are equal 111.
In a t-sql 2012 sql update script listed below, it only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value of 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?
UPDATE LKC SET LKC.combo = lockCombo2 FROM [LockerPopulation] A JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number
I would like to know different possible ways in appending extra values like new uniqueidentifiers, sequence numbers, random number. Can you please tell what type of data flow components helps us ?
I have a database that has entries that I want sorted by date order. Each entry has an auto ID number allocated (primary key auto sequencing), which I want to change to reflect the sorting (so the first date has the first auto ID number and so on).I've gone into the database and sorted the entries as I want them. Then I've gone into Design View to delete and restablish the primary key autosequence. However, it is not keeping the date order in the database (ie entry ID 3140 date is 12/06/2015, but 3141 is 02/02/2012). How do I get it to maintain the order?
I have a report with a column which contains either a string such as "N/A" or a number such as 12. A user exports the report to Excel. In Excel the numbers are formatted as text.
I already tried to set the value as CDbl which returns error for the cells containing a string.
The requirement is to export the column to Excel with the numbers formatted as numbers and the strings such as "N/A' in the same column as string.
Why does M$ Query Analyzer display all numbers as positive, no matterwhether they are truly positive or negative ?I am having to cast each column to varchar to find out if there areany negative numbers being hidden from me :(I tried checking Tools/Options/Connections/Use Regional Settings bothon and off, stopping and restarting M$ Query Analyer in betwixt, butno improvement.Am I missing some other option somewhere ?
I have a table with a column ID of ContentID. The ID in that column is all NULLs. I need a way to change those nulls to a number. It does not matter what type of number it is as long as they are different. Can someone point me somewhere with a piece of T-SQL that I could use to do that. There are over 24000 rows so cursor change will not be very efficient.
I have an 'ID' column. I'm up to about ID number 40000, but not all are in use, so ID 4354 might not be in any row. I want a list of all numbers which aren't in use. I want to write something like this:
select [numbers from 0 to 40000] where <number> not in (select distinct id from mytable)
Hi, I'm new to sql server but have used oracle sequence numbers to create unique keys in my tables. I've been looking for examples on how to create a sequence type table in sql server and have also found that there is a column called identifier but am unsure how to use this... I created a table and used this column attempting to insert (thinking it would autoincrement) but it fails... Any insight into how I can accomplish a sequence type activity for unquie numeric ids would be helpful, Thank you for your help,Jay
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, dev1aspnet
I have created the table test with the same structure and the same data in SQL Server 2005. To show the subnodes of the root node 2461, the following SQL Statement is used:
WITH CTE_TEST(PARFOLDERNO,FOLDERNO) AS ( SELECT PARFOLDERNO,FOLDERNO FROM TEST WHERE FOLDERNO=2461 UNION ALL
SELECT TEST.PARFOLDERNO,TEST.FOLDERNO FROM TEST, CTE_TEST WHERE TEST.PARFOLDERNO=CTE_TEST.FOLDERNO )
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.
The script below works but i have a break when datediff (days,startdate, endate) reaches 0. For every bookidm i want to iterate till the datediff is zero then move on to next bookid and do the same thing.
hi,1. is there a statement in ms sql, what creates a sequence? cant findanything in web :-(-oracle: CREATE SEQUENCE XYZ INCREMENT BY 1 START WITH 1 NOCYCLECACHE 20;-ms sql: ???2. hwo do i create a link to another ms-sql databasethx a lot need help, urgend :-)
I am designing a database. I want to define a automatic sequence on a table primary key field. what is the best solution for it?I know I can enable identity property for a field, but it has some problems ( for example its seed jumps on restart and unsuccessful events).I also can use some calculated sequences. for example I can calculate max of the filed values and after incrementing use it as key for new inserted record.
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?
We are trying to upgrade a SQL server 2000 to a SQL 2008 R2 (SP1) server. After migrating, the developer test code, and got an error: ERROR [HY010] [Microsoft][ODBC SQL Server Driver]Function sequence error...But this is a release for 2008, ours is already 2008 R2 SP1, so that hot fix should already be included since it is always cumulative.
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.
;with testdata as( SELECT 1 AS Id,'1/6/2014' AS Date, 21 As Amount UNION ALL SELECT 1 ,'1/8/2014', 25 UNION ALL SELECT 1 ,'1/9/2014', 30 UNION ALL SELECT 1 ,'1/10/2014', 60 UNION ALL SELECT 1 ,'1/5/2015', 3800 UNION ALL SELECT 1 ,'1/6/2015', 7120 UNION ALL
So, I have some questions about best practice in SQL Server.
1.) I have PK like this (company TINYINT, store TINYINT, action TINYINT, invoice INT, sn SMALLINT). I know JOINS will work faster with surrogate key but I have only couple of JOINS on that table. I use members of PK in WHERE clause mainly, alone and combined for reporting purpose. Is it always better to have surrogate key because they don't have any meaning and context of data laying in current PK.
2.) In my PK from above I have two candidates for using Sequence object. Invoice start with 1 for every (company,store,action) combination. Sn start with 1 for every (company,store,action,invoice) combination. I would like to know can I implement Sequence object here knowing that Sequence don't support PARTITION BY in OVER clause. From what I red it cannot be done via Sequence but I have to ask.Here is data sample for this PK
