Hi,
I am migrating a project from Oracle to SQLServer and must use the same DDL.
The entities have compound primary keys. In Oracle I ensure the compound key is unique by using a sequence table to generate one of the values for the compound key.
Does SQL Server have sequence tabels or does anybody know a way to get it do something similar?
Thanks
I'm new to sql server 2005. Previously I used Access. I've noticed that in sql server when a record is inserted into the database table, the data does not get entered sequentially. I looked at the id column and saw that the order numbers are mixed up. Is this something that is common in sql server, and how can I change this. I need the data to be ordered in the order that it was inserted into the database.
Can someone please help.
OK - maybe my Google-fu is off today but I'm trying to find out if using a sequence table will provide values that are as unique as the GUID is supposed to be.The reason is that I'm building a DW from the ground up (they won't let me expense my booze which I think is grossly unfair ) and rather than using GUID it ~seems~ like a sequence table would give better results. My concern is that the values won't be unique across tables.
View 9 Replies View RelatedI 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
Hi all,
In my project i will have the data in a collection of objects, I need to update series of tables with foreign key relations
Right now my code looks like this
foreach(object obj in Objects){
int accountId=Account.Insert(obj.accountOpenDate,obj.accountName);//this will update the accounts table and returns account id which is a Identity column in Acccounts table
int DebtId=Debt.Insert(accountd,obj.debtamount,obj.debtbalance); this will update the Debts table and returns DebtId
///series of tables like above but all the relevant data comes from obj and in the Insert Methods i am using stored procedures to Insert the data into table
}
The no of objects varies from 1000 to 1 milliion,, with this approach its taking more time to update all the data. Please let me know if any alternative procedure to handle this kind of scenario.
Thanks

I've been working on an SSIS package trying to load some data and the archive sequence is faulty. I've been trying to load a few tables created in a previous sequence into a local archive file and I've been getting the error "Could not find a part of the path."
The results aren't telling me what it's finding last and so I don't know where to start.
And the source DOES have data in it. It's something between the source and the destination.
Hi,
How can I generate a sequence No. using a simple SELECT statement.

View 1 Replies View RelatedI have a SQL 2005 stored procedure to generate an email when passed parameters such as receipient, subject etc
One of the paramteres passed to it is @body which is the body text of the message. I want to be able to add a couple of blank lines and then some footer information. This is working right now except I can't find the right way to add newlines into the string within the store procedure, so my footer information just tags right on after the bodytext.
I have tried but that literally adds the two characters and n
Can anyone advise how to generate newlien sequences in T-SQL.

Hi,
I have a question with this query -
SELECT * FROM table1 WHERE column1 = 'T_C_%';
This query returns rows where column1 = "T_Care", "T_CRP" etc etc, whereas I was expecting only rows where column1 = "T_C_Tail", "T_C_Head"
However, when I use an escape character(/), the results are more in the lines of the expected results.
Can somebody explain this?

I have the following stored procedure:
CREATE PROCEDURE dbo.ABR_HDR_INSERT
@id int output,
@status int,
@mode int,
@sessid varchar(100)
AS
declare @ay char(4)
declare @ddo char(4)
declare @abrid varchar(50)
declare @seq_no int
SELECT @ddo = a.DDO_DSCR_SHORT
FROM dbo.DIM_DDO a
JOIN dbo.Temp_ABR_HDR b
ON a.DDO_ID = b.DDO
WHERE b.SESSIONID = @sessid
SELECT @ay = AY
FROM dbo.Temp_ABR_HDR
WHERE SESSIONID = @sessid
-- set the default seq_no
SELECT @seq_no = 1
-- get the max abrid. if no record return the seq_no will be 1
SELECT @seq_no = convert(integer, max(right(abrid, 4)))
FROM dbo.ABR_HDR
WHERE left(abrid, 7) = @ay + @ddo
-- convert @seq_no to string prefix by 0
SELECT @abrid = @ay + @ddo + right('0000' + rtrim(convert(char(4), @seq_no)), 4)
Insert into dbo.ABR_HDR (ABRID, HDR_MODE, HDR_DDO, HDR_AY, HDR_REQUESTOR, HDR_DT, HDR_SUBJECT, HDR_DESCRIPTION, HDR_STATUS)
SELECT
@abrid,
@mode,
DDO,
AY,
REQUESTOR,
DT,
SUBJECT,
DESCRIPTION,
@status
FROM dbo.Temp_ABR_HDR
SELECT @id = @@identity
return @id
GO
ABRID gets inserted as a <NULL> value. I can't figure out why? If I comment out the following then ABRID will insert without the sequence number:
CREATE PROCEDURE dbo.ABR_HDR_INSERT
@id int output,
@status int,
@mode int,
@sessid varchar(100)
AS
declare @ay char(4)
declare @ddo char(4)
declare @abrid varchar(50)
declare @seq_no int
SELECT @ddo = a.DDO_DSCR_SHORT
FROM dbo.DIM_DDO a
JOIN dbo.Temp_ABR_HDR b
ON a.DDO_ID = b.DDO
WHERE b.SESSIONID = @sessid
SELECT @ay = AY
FROM dbo.Temp_ABR_HDR
WHERE SESSIONID = @sessid
-- set the default seq_no
--SELECT @seq_no = 1
-- get the max abrid. if no record return the seq_no will be 1
--SELECT @seq_no = convert(integer, max(right(abrid, 4)))
--FROM dbo.ABR_HDR
--WHERE left(abrid, 7) = @ay + @ddo
-- convert @seq_no to string prefix by 0
--SELECT @abrid = @ay + @ddo + right('0000' + rtrim(convert(char(4),@seq_no)), 4)
SELECT @abrid = @ay + UPPER(@ddo)
Insert into dbo.ABR_HDR (ABRID, HDR_MODE, HDR_DDO, HDR_AY, HDR_REQUESTOR, HDR_DT, HDR_SUBJECT, HDR_DESCRIPTION, HDR_STATUS)
SELECT
@abrid,
@mode,
DDO,
AY,
REQUESTOR,
DT,
SUBJECT,
DESCRIPTION,
@status
FROM dbo.Temp_ABR_HDR
SELECT @id = @@identity
return @id
GO
So, the code that sets the sequence number is what is causing the <NULL> value.
Any help is appreciated.
Thanks,

I am using a cursor right now and it takes a lot of time if my table is large.
Is there a more efficient way of doing this.
Thanks much.
is it possible to generate a number sequence in a query (without using loop). I want the output to look as
-------
ID
-------
1
2
3
4
5
6
7
8
9
....
upto the last number I give in the query
I am not sure about the ANSI/ISO rules on this? We have a SEQUENCE and insert it into a table.
CREATE SEQUENCE Cheque_Seq
AS INTEGER
START WITH 1
INCREMENT BY 1;
CREATE TABLE Cheque_Book
(cheque_seq INTEGER*NOT NULL PRIMARY KEY,
cheque_amt DECIMAL (15,2) DEFAULT 0.00 NOT NULL);
If I do an insertion with the SEQUENCE in a transaction and then ROLLBACK the transaction, what happens to the sequence value? My thought is that the value should reset to the state it was in before the transaction (basic definition of a ROLLBACK). But it does not in the products I have looked at.
Hi SqlGurus,
I have created table T1 as
created table t1 (no int not null primary key,name varchar(30))
i have created a sequence for this table
when i give the following insert statement
insert into t1 (name) values ('xyz')
the next sequence val should be inserted in column no
this is done generally in oracle with before trigger
how about here .Can we do this ?
Hi
I need to create a function that will return a sequence number. The reason I need this to be a function is that I will use the function to create a view. In Oracle I would do something like this:
create sequence seq;
create or replace function f return number
as
l_seq number;
begin
select seq.nextval into l_seq from dual;
return l_seq;
end; /
create or replace view v as select f from dual;
Since Sql Server does not have a sequence object I have created a sequence table with a identity column and a procedure that inserts a dummy variable and returns the identity id. This works ok but to get my sequence number I must declare a variable, execute the procedure and select the return value.
I need the procedure to be a function so that I can use it to create my view. Since I cannot use DML in a function and I cannot call a procedure from a function I am stuck. Do I have to create an extended procedure ? Any help is appreciated
hey all,
im having some problem to do this. i have this one table, that has sequence for other table.
table : tblpicksequence (this sequence is dynamic eg : Non=1, cons=2, RET=3)
picktypepicksequenceitemref
RET1x1
Non2x1
Cons3x1
i need to select record from other table depend on tblpicksequence sequence
table : tbldetail
idRETNonCons
1001
2110
3100
4 001
so base on tblpicksequence, RET=1, NOn=2, Cons=3, i need to list the record from tbldetail :-
i.list all RET=1
ii.if (i) not exists list all Non=1
iii.if (ii) not exists list all Cons=3
i expect :-
idRETNonConspicksequencepicktype
21101RET
31001RET
~~~Focus on problem, not solution~~~
I'm looking for a query that will look at an Id field and if it occurs more than once then returns the count of the times it occurs. For Example,

Hello to every body
I need to know about sequence of execution in a select command.
I have a sql command that use a function.some thing like:
select id, function(item)
from tbl
where conditions...
I want to know that if my function on item execute before where section or vise versa.
I try to explain it more. I want to know that sql engine fetch rows accordin to where clause and then execute my function or execute my funtion and then fetch the rows according to where clause.
If you have a document or some thing that explain about sql engine and sequence of execution please let me know.
Your help is really appriciated.

Hello all,Iīm currently using a SQL Serve 2K. Would like to do a selectwhich returns the row number - this should not be physically stored inthe database. So for example, I would like to do a query against theCUSTOMER table and receive:* rowID || name1 Evander2 Ron3 Scoth4 JaneI donīt want to store the ID, because if I change the order byclause, the sequence may modifiy, and, for another example, having thesame set of data, I would receive:* rowID || name1 Scoth2 Ron3 Jane4 Evander could someone help me ?best regards,Evandro
View 3 Replies View RelatedHello,Since SQL Server has no sequence generator, I wrote my own. (I claimno ownership of it as it is closely modeled after earlier discussionson this topic.) I have included the sql statements below.While it works independently on its own, It seems to lock in multi-userenvironments or in nested-transactions. It s funny really: I have mymain transaction, but the sequence generator below forces anothertransaction, which I do not really care for. I cannot remove the extratransaction from the sequence generator because I would like to discardany values it retrieved, regardless of whether the main transactionsucceeded or failed.Any suggestions?--------------------------------------------------------------------------------create table my_sequence (name varchar(10), seq int identity (1, 1))godeclare @next intbegin transactionupdate my_sequence set seq = seq + 1 where name = 'abc';select @next = seq from my_sequence where name = 'abc';commit transaction---------------------------------------------------------
View 6 Replies View RelatedI have 2 tables which tab B depends on the record on tab A. In publisher, records are generated to tabA before some audit information record to tabB. In subscriber, there is replication error that the trigger in tab B couldn't find the corresponding record in tab A and cause the transactional replication error. And I found the comand_id within the same xact_segno of record in tab B is smaller than that of record in tab A. Does it mean the data in tab B replicate before tab A?
Also, how to know the replication sequence to the subscriber?
