Transact SQL :: How To Change Auto-sequence Numbers To Match Sorted Data
Jun 15, 2015
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?

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 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
[Code] ....

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.
Example table:
numez numhx
111 111
111 111
0 111
111 0
111 0

Please find the necessary SQL to create the table with sample data down below.In this simple table, I'm keeping project status logs i.e. what project, what happened and when.I want to create a select statement that will give me the ProjectId and the time stamps from "Contract Signed" to "First Meeting". So, I'd like my data to look like this:
ProjectId - FromStatus - FromTimeStamp - ToStatus - ToTimeStamp
123 - 'Contract Signed' - 6/21/2015 3:33PM - 'First Meeting' - 6/27/2015 8:45AM
456 - 'Contract Signed' - 6/25/2015 9:00AM - 'First Meeting' - 6/29/2015 2:50PM
987 - 'Contract Signed' - 9/29/2015 11:00AM - 'First Meeting' - 7/11/2015 10:00AM
Please notice that in my SELECT statement, I don't want to see anything else. For example, I don't want ProjectId: 555 included because it never made it to "First Meeting". I also don't want to see any information about "Press Release" for ProjectId: 123. I only want to see those projects that went from "Contract Signed" to "First Meeting".
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

SET ANSI_PADDING ON

CREATE TABLE [dbo].[ProjectStatus](
[LogId] [int] NOT NULL,

I have the following data in a table:
Account SEQ
12345 1
12345 2
12345 4
12345 5
12345 7
I need to fix the SEQ field so that no gaps exist, like this:
Account SEQ
12345 1
12345 2
12345 3
12345 4
12345 5
Is there a way to do this with T-SQL?

Is is possible to Generate sequence numbers in a Query result in an SQL select Statement
like
Select sno,employee_name from empmaster
sno being a number with auto increments(this Field will not be in a Table).
I do not want to use Identity .....
This is Just to Provide a Serial Number to the Query Output...
thus the Out put should be something like
sno employeename
--- ------------------
1 abc
2 jhjk
3 kljl

hi all
I am stuck with something that seems easy but im obviously clueless as how to execute the idea.
I have a custom table that houses invoices on the details level. So for example i have:
InvcNo
00000001
00000001
00000001
00000002
00000002
00000003
and so forth
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.
Thanks

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?
Many thanks,
Fred

How can I create a number sequence starting at a certain number and continue on for the number of records I have.
For example I have 3000 records in my table and a field named I created called RecordId which I'd like to start at number 1 and goto 3000 (or maybe even start at 9000 and goto 12000 or however many records there are).
In my pseudo SQL code Im guessing it would be something like...
select * from Incident
update Incident
set RecordId( i=9000; i<=Number of Records in Table; i++)
Whats the easiest way to do this?

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 ) ;

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.

Hi,Please can you let me know the best solution for creating a primary key which automatically increments by 1 each time a record is added. My current Primary key is of type "Int" which increments by 1 each time, but I would like my primary key to contain "ABC" before the 1. So each time a record is added I would like to see:-ABC000001 ABC000002ABC000003Etc, EtcI am using SQL Server 2000 and creating an ASP.Net application, will I need to write code in a Stored Procedure to do this?Regards,Brett

Hi There,I am having a strange problem with my identity column...... 1). I have a table of Products that have an identity column auto-incremented by 1. 2). I have my asp program working quite well in which the Data entry operators are adding the products into my database..... and they do not have any interface through which they can delete products........ 3). My Database is running at Web server(MS SQL Server)My problem is that when i cehcked my database.... there were around 1000 records but the auto increment number have reached to 1500. and when i checked in details then i saw that Auto number column is being skipped certain numbers..... like one entry is 1478 then the next one comes to be 1482..... and 1508 to 1516........ Its happening alot of times and it seems that SQL Server is skipping some numbers............Since it is Auto-Number so i do not have control over it through my code.... So i think the coding might not be the problem...... I have set Identity seed as well as Identity Increment both to 1.Is there any thing that you can suggest me to do??(Thanx)

I have 5 tables that are joined respectively,
Each one of the tables listed below has a “CreateDateTime” and “UpdateDateTime” fields, I need to get yesterday changes, I can get any record where either CreateDateTime or UpdateDateTime is greater than midnight yesterday butI need to watch dates on all of the tables so I need to do atleast 10 date checks.
If any table shows an updated or created record, I need to gather ALL of the information for that customer. So, if my name didn’t change (SCUS table), but my email does (SEML table), I have to pull out both the SCUS and SEML tables (and the others, of course). So It may not be simple WHERE clause, How can I achieve this:
SELECT
SCUS.CUSFULLNAME
,
SCUS.CUSMIDDLENM
,
SCUS.CUSLASTNM ,

I have created a table from another table where I specified that one of the fields, an number field, is sorted in ascending order and have NOT specified that it is to be an indexed field and there are 10 million records, from 1 to 10,000,000 exactly.
Now, if I query that table, asking to return records 1-1,000 from that non indexed number field that I sorted in ascending order (where number field <= 1,000) , will it run as fast as if it were indexed?
In other words, does SQL know somehow that these records are sorted in ascending order and so will not do a full table scan, stopping at 1,000 to return my data set?
Or is there no way for SQL to know this and only specifying an indexed field allows SQL to know that its in some order and so it doesn't have to do the full scan?

I have four tables that need to be loaded into an ASP.NET application. They need to be loaded together into one result set and sorted. Is it possible to load four tables together and sort them using an SQL statement?
To clarify, say I have the following data:
Table1: Anglesey, Cardiff, Ceredigion
Table2: London, Dorset, Lancashire
Table3: Antrim, Armagh
Table4: Glasgow, Berwick, Edinburgh
I'd want the data retrieved from all four tables and sorted so that the data retrieved would be:
Anglesey, Antrim, Armagh, Berwick, Cardiff, Ceredigion, Dorset, Edinburgh, Glasgow, Lancashire, London
I am aware of and am using the SELECT ... ORDER BY feature of MSSQL in my present ASP.NET application to retrieve from single database tables. I'm using merged datasets and a sort method to solve the above problem at the moment.

Please don’t look for table design satisfies NF, this is just for example
Student table
Id StudentId
1 10
2 20
3 30
Student_Class
Id ClassId
1 100
1 101
1 102
1 103
2 100
2 101
When I give studentId 10 and class ids = 100, 101, 102, 103 then result should be get row from student table only if all given class ids matched.
Result:
Id Student ID ClassId
1 10 100, 101, 102, 103
Case 2: Student Id: 10 class Ids = 100, 101 the no results since all the class ids for student 10 in Student_Class are not matching with the given class Ids parameter.

I need a simple tSQL code that will produce an array sequence values that has gap with 2 or more consecutive values, which can vary - so 2 or 3 or 4 between sequence of number. For example, I want it to return a series with a gap or space of 2- So it should return 1, 2, 5, 6, 9, 10.. or a gap of 3 - 1,2 ,6,7,11,12.. etc I know a single gap is quite simple using a recursive cte, but I haven't been able to find how to get this kind of result.

We have an app that supports any version of sql beyond 2008. What we are finding is that users are upgrading to new versions of sql and just restoring their db on the new version of sql and not changing the compatibility level. I would like a script that would change the db's compatibility level to match whatever version of sql that they are using.
ALTER DATABASE db_name
SET COMPATIBILITY_LEVEL = (SELECT TOP 1 compatibility_level
