I need to create a simple audit trigger for a table with 12 columns. I need to determine which row was changed. Is there a simple way to do that. The table structure is
ID Integer(4)
barcode(25)
epc_tag(24)
bc_stop_flag(1)
reject_flag(1)
complete_flag(1)
hold_flag(1)
pe_1_flag
pe_2_flag
pe_3_flag
pe_4_flag
pe_5_flag
This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.
The following code write audit entries to a Table called
'Audit'
with columns
'ActionType' //varchar
'TableName' //varchar
'PK' //varchar
'FieldName' //varchar
'OldValue' //varchar
'NewValue' //varchar
'ChangeDateTime' //datetime
'ChangeBy' //varchar

hi, im kinda new to sql and was just wondering if someone could help.
i need to create a trigger that saves all changes from a table(table1) to an audit table.
-table1-
item_code
item_price
item_description
I wont to get text of statement which chaged actual table.
with this script :
Code Block
if object_id('dbo.mytable') is not null drop table dbo.mytable
go
create table dbo.mytable (f1 varchar(100))
go
alter trigger dbo.ti_mytable on dbo.mytable for insert
as
set nocount on
print 'in trigger'
DECLARE @sql_handle binary(20)
select @sql_handle = sql_handle FROM master.dbo.sysprocesses p (nolock) where spid = @@spid
select @sql_handle, @@spid, [text] FROM ::fn_get_sql(@sql_handle) as statement_text
GO
if I execute
Code Block
insert into mytable values ('test')
I getting text of the trigger. How I can get @sql_handle of original statement ?
Hi,
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname
Thanks,

I have a trigger on my Table (MyTable). The Trigger saves any changes to mytable. The AuditTrails table has this columns: ID, TableName,PrimaryKey, OLDvalue, NewValue,UserID,DateCreated.
Now, how can i pass the application's UserID (Not the SQL Server User) and save it to the AuditTrails table?
In my .NET Application, if someone delete a record from myTable how can i possibly get the userid of that person using my Audit trail Trigger?
Hi all,
I'm trying to create a audit trail trigger. I'm new to SQL Server. For simplicity sake, let's just say I have a table like the following:
Table1
FieldA
FieldB
And the audit table is:
Table1_Audit
FieldA
FieldB
Operation (Insert/Update/Delete)
Operator (Username)
Op_Date (GetDate())
Ok, simple enough. Now, I'm using Studio Express and there are several templates available. By default this is the one I get:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER <Schema_Name, sysname, Schema_Name>.<Trigger_Name, sysname, Trigger_Name>
ON <Schema_Name, sysname, Schema_Name>.<Table_Name, sysname, Table_Name>
AFTER <Data_Modification_Statements, , INSERT,DELETE,UPDATE>
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for trigger here
END
GO
Not sure if I need all of this information? Examples I've found on the web look very confusing...ugh. I looking for simple (if possible).
Many thanks in advance,
Mark
Greetings
I'm clear about the use of a DELETE trigger to "move" your deleted record to a second database as a sort of recycle bin.
But SS7 has the limitation, and it's mentioned in BOL, that it cannot reference your TEXT, NTEXT or IMAGE fields in the DELETED table. It says to join the original table with DELETED to get at those fields.
The only problem is the original table's record has been deleted! Even though the transaction has not yet been COMMITTED.
Here's my Trigger:
CREATE TRIGGER AuditTest ON Activity FOR DELETE AS
INSERT AuditDB.dbo.Activity
SELECT Activity.* FROM Activity INNER JOIN Deleted
ON Activity.ActivityID = Deleted.ActivityID
And for discussion, here's my Table:
ActivityID uniqueidentifier
OrgId uniqueidentifier
Title varchar(600
Active bit
Comments text
LastUpdate datetime
Any suggestions? Has anyone been able to implement a DELETE Audit
Trigger on a table with BLOBs?
Thanks,

I have a requirement to audit tables in a SQL Server database. The tables are dynamically created when the application creates a form and the table holds the form data. So my plan is this, I have worked out the audit table (static) and the trigger. What i'm having issues with is getting the trigger to create from within the stored procedure. So just to recap: the user creates a form in the app, this creates a table and should call this stored procedure. The stored procedure creates the trigger on that table (which begins auditing that table, inserting to the static audit table based on the table name being passed into the stored procedure).
Where im at: I can create the stored procedure. When i go to run the stored procedure, I get the errors after passing the table as a value.
In my opinion it's an error with the correct number of single ticks, but not sure.
The Code:
USE [AdventureWorks]
GO
/****** Object: StoredProcedure [dbo].[spReplaceAuditTrigger] Script Date: 12/06/2011 15:28:50 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROC spReplaceAuditTrigger( @PassedTableName as NVarchar(255) ) AS

Hi,
I am trying to figure out which of these option is best suited for auditing. Although each one of them has its own pros/cons.
CLR trigger is easy to write and can be made generic so that it fits for any table required to be audited.
I tried both the option in test database and i found the CLR trigger performed poorly.
Results were :
For table A (3 columns) with TSQL trigger took less than a sec for 2500 sequential inserts.
While table B (3 columns) having same structure with CLR trigger took more than 20 sec for 2500 sequential inserts.
Has anybody done performance comparision of this 2 approaches ?
Please share results if any.
I wanted to validate that is my findings correct so that i select best optimized approach.
Thanks,

I have a update trigger on a table which fires trapping the userid and time in the same record. The code is below. The tirgger only works if I have the recursive triggers option unchecked on databae properties. Is the way I am trying the only way to accomplish this in the update trigger or is there an more efficient way. Thanks

I need a trigger to know who and when a char(1) column is changed. Â Would like to write the audit trail to its own table I can query and record before and after values.

[Active] [char](1) NULL DEFAULT ('N') --Must use char 1 b/c more than 2 possible values
)
Insert into Test (Customer, Active) Values ('Acme','Y')..I want trigger to tell me whowhenwhere this value was changed. Â If using sql auth capture client windows id if possible and write to audit table Update Test set Active = 'N'

I have a table called my_history that has columns like this
column_name , old_value, new_value, key, date
bankaccount 30 50 1 01-Apr-2008
bankbalance 10 14 2 04-Apr-2008
and so on............
The history table is populated using triggers
The main table called my has a structure like
bankaccount bankbalance bankname name address key
50 50 xyz abc ford 1
30 14 abc xyz east 2
Now using this information can i reconstruct the records in my table before the update happened ?
I am finding it very difficult to do this is there a way to do this in t-sql ?
The problem is my_history table where the column_name keeps on varrying

I have made a server security audit and specify from database audit specification to audit "select" on a certain user and on a certain table. I logged in by this user and made the select statement..when i run this query
"select * from sys.fn_get_audit_file('d:Auditaudit1*',null,null)"
It return a value at which time the query has done
after 15 minutes i repeated the same action, i run the audit query and the same result is showed off on the panel.is it suppose to return a list of values by how many times this user has made the select statement on that table ? for example at 5:00 pm then 6:00 pm and so on
I write a insert trigger on my table LeaveRegister(1000 rows) and inserting rows in audit table, but when i inserting a row in LeaveRegister table. In audit table 1000 + 1 rows are inserting every time.

View 3 Replies View RelatedI need help...here is the problem.Last weekend, the servers in our datacenter where moved around. After thismove, and maybe coincidental, 1 server is performing very poor. Afterrunning a trace with SQL Profiler, I saw the problem which was laterconfirmed with another tool for SQL server performance monitoring. It seemsthat all connections to the SQL server (between 200 - 400) are doing a login/ logout for each command that they process. For example, the user'sconnection will login, perform a SELECT, and then logout. This is not a..NET application. The client software was not changed, it is still thesame. The vendor has said that it is not supposed to do that, it issupposed to use 1 connection that log's on in the morning and logs off atthe end of the day or whenever the user exits. 1 user may have severalconnections to the database.At times, the server is processing over 250 login / logouts (avgeraged for30 second period). Has anyone seen this problem? I have the server inAUDIT FAILUREs only. The server has become very unresponsive, things thattook 3 seconds now take over 15 seconds.Any ideas???

I have a table that has a number of data fields,I need to be able to capture datatime when the date field was entered or entered value changed.I was told I need to create a trigger on that table that contains all the fields.
I have seen the syntax for creating triggers, and read some documentation but I am still in the dark as how to create what I need to.
I was hoping to see if somebody had a similar example or an advice, anything is more than what I have at the moment.

Guid(PK)Not Null,
AcademyId(FK), Not Null,
Name,Null
WorkPhone,Null
CellPhone,Null
Email Id,Null
Other.Null
Since we have given Null to ''Workphone'',''Cellphone '', ''Email ID''.when inserting the data into these table.if the particular columns are empty while inserting also the data will get populate into the table.And.I need is if these columns are ''Workphone'',''Cellphone'' , ''Email ID'' they cant insert the data into table.
Like it must trigger like ''Please enter atleast one of these ''Workphone'',''Cellphone'' , ''Email ID'' columns.

CREATE TRIGGER EileenTest ON OrgCouponTestMainFOR InsertAS declare @emailaddress varchar(50)declare @body varchar(300)declare @fname varchar(50)declare @coupon varbinary(4000)
if update(emailaddress)begin
Select @emailaddress=(select EmailAddress from OrgCouponTestMain as str), @fname=(select EmailAddress from OrgCouponTestMain as str) @Coupon=(select OrgCoupon1 from OrgCouponTest2 as image)
SET @body= 'Thank you' +' '+ @fname +' '+ ',Here is the coupon you requested' +' ' + @couponexec master.dbo.xp_sendmail @recipients = @emailaddress, @subject = 'Coupon', @message = @bodyEND
I have the following
CREATE TRIGGER dbo.tgrCacheCustomers
ON dbo.Customers
FOR INSERT, UPDATE, DELETE
AS
EXEC sp_makewebtask 'C:DependencyFile.txt','SELECT top 1 CustomerId FROM customers'
and I get the following error that I dont understand:
Error 21037: [SQL-DMO] The name specified in the Text property's 'CREATE ...' statement must match the Name property, and must be followed by valid TSQL statements.
Any ideas someone?
