How To Add A Newline Sequence

Apr 9, 2007

I 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.
Regards
Clive

Escape Sequence

Sep 1, 2004

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?

Sequence Number Help

Nov 17, 2005

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,

Sequence Tables

Feb 1, 2007

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

suppose I have the following table grouped by memid

memiddx

below

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.

Sequence In Rollback

Oct 16, 2014

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.

Sequence From A Function

Mar 10, 2006

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

Sequence Generator

Jun 19, 2006

Hello,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---------------------------------------------------------

Replication Sequence

Apr 29, 2006

I 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?

Thanks in advance!

Sql Server Sequence Column?

Oct 7, 2006

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

Insert Into Sequence Field

Mar 25, 2002

What I want to do is: insert into newtable (field1, field2, sequence) select
(fielda, fieldb, #) from oldtable and have the sequence field "re-seed" to 1 every time the value in fielda/field1 changes. This added requirement makes this not an identity field problem, if I understand identity fields. This is a data conversion problem, so I'm converting 1000's of rows from oldtable to newtable and want the sequence to re-seed at every change in value of the fielda/field1 data; in fact fielda/field1 is a simplification as there could be multiple controlling fields forcing a re-seed.

TIA...Al
