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 ?
I would like to use sequences and triggers to update table identity field with int value from sequence via before insert trigger. I'm searching on google for a few days and there are no same or identical article about this subject.
Is there any sample how to create table with column Id, Name, Comment and sequence (for generate int numbers for Int field in table) and trigger which will fired before insert and check is inserted Id is NULL and update this field from sequence or nothing if id is set up.

i'm creating a sql hoilday database and i need to write a sequence but i've been told its wrong but i dont know why, can anyone help?

Im doing a quickie Access Project for a Fileroom orginization DB. Generally, Records are addressed by a 7 character unique ID, with all sorts of rules, assigned by another system. However we need to track Items that for various reasons do not exist in that system. For this, we enter a code that consists of 2 characters of invalid data, followed by a simple incrementing number. In Oracle, i would do this with a Sequence. How do I go about this in Sql Server?basicly, I want to write a trigger that says something like: pseudo code wrote:before insert: if :new.ItemType is Type3 Then-- File local to our file room :new.FileID = "IV" + getNextLocalNumber().ToString() end ifNote that the fileID is not a Key in the normal DB Sense. It is a neumonicly unique identifier w/ some other properties so that people can easily look things up.

there is this little dumb thing i don't manage to understand about sequences
when i create a table i put the id as the primary key and write something like this
Code Block[Id] [int] IDENTITY(1,1) NOT NULL,
so each time the sequence is incremented by,
but if i delete a line from a table and then insert a new one
instead of inserting the id 3 for example it inserts id = 4
how can i change this definition sothat if i do
Code Block
delete from table
where id=3
and then i want to to
Code Block
insert into table values ...
it gives a this new line
Code Block
id columnA
3 A
and not
Code Block
id columnA
4 A
thanks in advance for the help
All,
What is the escape sequence in a stored procedure?
Here is what I'm trying to achieve:
ALTER PROCEDURE Test
(
@Func VarChar(1000)
)
AS
DECLARE @SQL VarChar(8000)
SELECT @SQL = 'SELECT DISTINCT TNAME FROM TABLE WHERE FUNC LIKE ' + @Func
Now, my goal is to add single quote (') before @Func and another one after that. For eg, if @Func is "Test", I want my query to be
SELECT DISTINCT TNAME FROM TABLE WHERE FUNC LIKE 'Test'
and NOT
SELECT DISTINCT TNAME FROM TABLE WHERE FUNC LIKE Test
Any help?

View 1 Replies View RelatedI am working on a text mining application wherein I need to detect unusual/anomalous sentences in text. Certain sentences, that I know occur very frequently, are given a likelihood of 0.2 by PredictCaseLikelihood. Other sentences that are just as frequent get a much higher likelihood (>0.9). I am using the NORMALIZED option. The only significant difference between these sentences is their length. The one with the lower likelihood has only 2 words in it, whereas the one with the higher likelihood has more than 10 words. The problem is that the shorter sentences end up being interpreted as anomalous, when in fact they are'nt. Any suggestions?

I've seen several posts about reading and writing files that have different record types with varying column metadata. My particular file has 11 record types plus several header types and looks something like:
<Header1>
<Header2>
<Detail01-#1>
<Subdetail02>
<Subdetail03>
...
<Detail01-#2>
<Subdetail02>
<Subdetail03>
...
...
Since i need to get different detail and subdetail records, i can't really use the technique of 3 dest file connection managers found in http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=87269&SiteID=1
I've tried using an exec sql to get the main detail records and then a forech ADO en umerator that would get the subdetails, but it all seems so kludgy. I'm starting to think that I should just write the bulk of the file creation code in a c# app instead of trying to smush this into SSIS. Opinions? Am I missing some trick in SSIS?
TIA,
-Peter
This isn€™t an problem as such, it€™s more of a debate.
If a table needs a number of update triggers which do differing tasks, should these triggers be separated out or encapsulated into one all encompassing trigger. Speaking in terms of performance, it doesn€™t make much of an improvement doing either depending upon the tasks performed. I was wondering in terms of maintenance and best practice etc. My view is that if the triggers do totally differing tasks they should be a trigger each on their own.

Is it possible to achieve this using triggers:When someone tries to delete a row in table A, the trigger should first delete a corresponding row in table B and then delete the row in table A. The reason being that, there is a foreign key set on Table B that references table A. So any attempt to delete a row in table A without deleting the corresponding row from B, throws an error.

I have to write Trigger for Update,

General Problem
I need to create a set of rows every time a new row is inserted into a table.
Example (I think this would work)...
select @insertedId = column1 from insertedselect @id = column1 from table1 where column2 in (select column1 from table2 where column2 = @insertedId)insert into table3 values(x, y, @id)
Is it possible to do the same kind of thing in a situation where the select statement returns multiple values and execute the insert statement for each of these values?
Also, if table3 was in fact the table on which the trigger acts, would it then be executed for every row created by the trigger?
Sorry if I sound confused. I am.

View 3 Replies View RelatedHi All,
I'm using triggers to handle my transaction log to cature inserts and updates. It works fine except if the user clicks on the Save button more than once, the trigger is fired and the record is written to the log even if the record wasn't changed. Does anyone know how to check if the record was actually changed so that it isn't written to the table if it wasn't?
Thank you,
Mike
When I execute a stored proc from my asp.net page, will the results of a trigger be returned to my program?
For instance say my stored proc is:
Update Employees set
(Lastname = @Lastname)
where ID = @ID
And my trigger is:
CREATE TRIGGER tr_Employees_U on Employees FOR UPDATE AS
IF UPDATE(lastname)
BEGIN
RAISERROR ('cannot change lastname', 16, 1)
ROLLBACK TRAN
RETURN
END
GO
It seems like since this is an AFTER trigger that my webpage would actually get a valid return code from my stored procedure however the trigger would rollback those changes correct? Or would the trigger get fired and send it's return code to my webpage?

View 3 Replies View Relatedl'm trying to build a trigger on a table. The reason for the trigger is to check a certain field for the first three characters if it has ie abc it must update another field in this case loanbook to newabc.How do l write the trigger so that it also check if exists and perform the updates. Please help its Urgent. l've listed the trigger below.
CREATE TRIGGER UpdTest_TRGData
ON Test_TRG
FOR insert,Update AS
IF left('Loan_No',3)='ABC'
update Test_TRG
set loanbook = 'NEWABC'
else
IF left('Loan_No',3)='DEF'
update Test_TRG set
loanbook = 'NEWDEF'
where loanbook is null
else
update Test_TRG
set loanbook =left('Loan_No',3)
where loanbook is null
I'm a bit confused on this bit please elaborate : " FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK ".
The PK is on which field? Basically this trigger should ensure that on insertion of o new loan if
The left(loan_no,3)=MCG and its null then NEWMCG
left(loan_no,3)=MCG and its null then NEWMCG
left(loan_no,3)=KVS and its null then NEWKVS
left(loan_no,3)=MFS and its null then MFS
left(loan_no,3)=TCR and its null then TCR
left(loan_no,3)=ABL and its null then ABL
Listed below is what l've tried to do but l'm missing the PK part.Otherwise everything else you explained
in the script is clear. Thanks man its urgent. When l parse the query its fine , but When l run it
l get an error.
CREATE TRIGGER UpdTest_TRGData
ON Test_TRG
FOR INSERT, UPDATE
AS
UPDATE Test_TRG
SET LoanBook = CASE WHEN LEFT( i.Loan_No, 3 ) = 'MCG' THEN 'NewMCG'

WHEN LEFT( i.Loan_No, 3 ) = 'ABL' AND i.LoanBook IS NULL THEN 'ABL'
WHEN i.LoanBook IS NULL THEN LEFT( i.Loan_No, 3 )
END
FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK
-- Fill in Primary Key or other Join Column(s)
WHERE LEFT( i.Loan_No, 3 ) = 'MCG'
OR ( LEFT( i.Loan_No, 3 ) = 'KVS' AND i.LoanBook IS NULL )

I an loading records from a flat file into a table, which is done everyday by a scheduled job in SQL Server 7.0.
How can I make sure that if the job is run twice in a day for some reason that the same rows are not inserted into the table again? Do I have to write a insert trigger on the table ??? If so how can I achive the objective ??

Hey everyone...
I'm working on trying to figure out how to update the child table from the parent via a trigger. This works fine as long as the value is in the child table. If it's not, then I get my foreign key violation. So, My next thought was to simply put in a begin tran / rollback tran within the trigger... My question is this : If I have multiple triggers on the parent table all based on the update of the key field (and the child tables... some 7 of them) all have FK's, if I rollback one trigger does it rollback the entire transaction? Or just the functionality of that trigger? From what I've read, it appears as if it's the entire transaction... if so, how do I get a trigger to 'ignore' itself or not fire based on a select criteria that i have within that same trigger...
Thank you...
I just tried creating my first trigger and I'm a little bit confused. I am trying to see if certain fields have changed and will do that by checking the values of the fields in the "master" table and the "Inserted" table. I wasn't sure which table would have the old data and which would have the new, so I created the following trigger to help me determine which was which:
CREATE Trigger upd_cost_master On tbl_cost_master
For Insert, Update As
Declare @U_Name varchar(65)
Declare @O_Name varchar(65)
Select @U_Name=I.submitted_by, @O_Name=O.submitted_by
From tbl_cost_master O Inner Join Inserted I On O.autokey = I.autokey
Print 'Inserted: ' + @U_Name
Print 'tbl_cost_master: ' + @O_Name
Commit Tran
To my surprise, @U_Name and @O_Name contained the same values. I though that one table contained the old values and one contained the new. Was I wrong? If so, is there anyway to compare the Old and New values through a trigger?

Hi,
I'm using SQL Server 7.0. I have an insert trigger on table t05r. I populate table t05r with a DTS package. The trigger is supposed to add the record which was inserted into t05r, into t39r. After I run the DTS package to populate t05r, I checked t39r and no records where added. What is going wrong? Is it that DTS uses bulk copy and triggers don't fire on bulk copy?
Any help would be greatly appreciated.
Thanks in advance,

I've update triggers on my table, But for some of the transactions, I don't want the triggers to fire. I know in Sybase there are set triggers off. In MS SQL, Is there any similar commands which will set triggers off for particular sql statements.

Hi! I am having trouble with setting triggers while doing my project. The project is on ATM machine driven through SQL. So I have Date of Transaction in one table and Account Expiry in another.
I want to set the trigger to check Account expiry when doing transaction so i wrote T-SQL
select........
getDate()-Dateoftransaction=expiry
begin '...'
end
the system saying I have got an error near the word 'begin'.
I am desperately needing help. running out of ideas.
Thanks in advance.
I need to create an after insert, update and delete trigger on the same table. Can I create one trigger that would have all three operations in it or I need to create three separate triggers? Thanks for your help.
