Hi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm.... This example seems to be workingfine so it must be something with my specific schema/code. We'reworking on running a SQL trace but if anybody has any input, fireaway.Thanks!create table x(Id int,Account varchar(25),Info int)GOinsert into x values ( 1, 'Smith', 15);insert into x values ( 2, 'SmithX', 25);/* Update trigger tu_x for table x */create trigger tu_xon xfor updateasbegindeclare @TriggerRowCount intset @TriggerRowCount = @@ROWCOUNTif ( @TriggerRowCount = 0 )returnif ( @TriggerRowCount > 1 )beginraiserror( 'tu_x: @@ROWCOUNT[%d] Trigger does not handle @@ROWCOUNT[color=blue]> 1 !', 17, 127, @TriggerRowCount) with seterror, nowait[/color]returnendupdate xsetAccount = left( i.Account, 24) + 'X',Info = i.Infofrom deleted, inserted iwhere x.Account = left( deleted.Account, 24) + 'X'endupdate x set Account = 'Blair', Info = 999 where Account = 'Smith'
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.  Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with: WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc. Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below) Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government] Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc. Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies. Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
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
using System; using System.Data; using System.Data.SqlClient; using Microsoft.SqlServer.Server;
public partial class Triggers { //A Generic Trigger for Insert, Update and Delete Actions on any Table [Microsoft.SqlServer.Server.SqlTrigger(Name = "AuditTrigger", Event = "FOR INSERT, UPDATE, DELETE")]
public static void AuditTrigger() { SqlTriggerContext tcontext = SqlContext.TriggerContext; //Trigger Context string TName; //Where we store the Altered Table's Name string User; //Where we will store the Database Username DataRow iRow; //DataRow to hold the inserted values DataRow dRow; //DataRow to how the deleted/overwritten values DataRow aRow; //Audit DataRow to build our Audit entry with string PKString; //Will temporarily store the Primary Key Column Names and Values here using (SqlConnection conn = new SqlConnection("context connection=true"))//Our Connection { conn.Open();//Open the Connection //Build the AuditAdapter and Mathcing Table SqlDataAdapter AuditAdapter = new SqlDataAdapter("SELECT * FROM Audit WHERE 1=0", conn); DataTable AuditTable = new DataTable(); AuditAdapter.FillSchema(AuditTable, SchemaType.Source); SqlCommandBuilder AuditCommandBuilder = new SqlCommandBuilder(AuditAdapter);//Populates the Insert command for us //Get the inserted values SqlDataAdapter Loader = new SqlDataAdapter("SELECT * from INSERTED", conn); DataTable inserted = new DataTable(); Loader.Fill(inserted); //Get the deleted and/or overwritten values Loader.SelectCommand.CommandText = "SELECT * from DELETED"; DataTable deleted = new DataTable(); Loader.Fill(deleted); //Retrieve the Name of the Table that currently has a lock from the executing command(i.e. the one that caused this trigger to fire) SqlCommand cmd = new SqlCommand("SELECT object_name(resource_associated_entity_id) FROM ys.dm_tran_locks WHERE request_session_id = @@spid and resource_type = 'OBJECT'", conn); TName = cmd.ExecuteScalar().ToString(); //Retrieve the UserName of the current Database User SqlCommand curUserCommand = new SqlCommand("SELECT system_user", conn); User = curUserCommand.ExecuteScalar().ToString(); //Adapted the following command from a T-SQL audit trigger by Nigel Rivett //http://www.nigelrivett.net/AuditTrailTrigger.html SqlDataAdapter PKTableAdapter = new SqlDataAdapter(@"SELECT c.COLUMN_NAME from INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk , INFORMATION_SCHEMA.KEY_COLUMN_USAGE c where pk.TABLE_NAME = '" + TName + @"' and CONSTRAINT_TYPE = 'PRIMARY KEY' and c.TABLE_NAME = pk.TABLE_NAME and c.CONSTRAINT_NAME = pk.CONSTRAINT_NAME", conn); DataTable PKTable = new DataTable(); PKTableAdapter.Fill(PKTable);

//Helper function that takes a Table of the Primary Key Column Names and the modified rows Values //and builds a string of the form "<PKColumn1Name=Value1>,PKColumn2Name=Value2>,......" public static string PKStringBuilder(DataTable primaryKeysTable, DataRow valuesDataRow) { string temp = String.Empty; foreach (DataRow kColumn in primaryKeysTable.Rows)//for all Primary Keys of the Table that is being changed { temp = String.Concat(temp, String.Concat("<", kColumn[0].ToString(), "=", valuesDataRow[kColumn[0].ToString)].ToString(), ">,")); } return temp; } }
The trick was getting the Table Name and the Primary Key Columns. I hope this code is found useful.
I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.
I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger on a for insert as insert into b(ID)
Hello All, I've been adviced without much detail that the best way to handle updates is with an Update Trigger to write to an AuditTable. I always thought it was better to avoid triggers. I'm getting confused very fast in reading about triggers. Could someone please point me in the right direction?
i am using address table to store the address of employees, agents, students; so can't use cascade update and delete. so i decided to use trigger but i got stuck here as well. Here employeeid is the PK of employee id. so when it is updated, i want to update that id in corresponding address table as well. so what i need is to find out the previous value of EmployeeID before updating to use in WHERE clause and new EmployeeID to use in SET clause.
<code> CREATE TRIGGER [AddressUpdate] ON [dbo].[MCS_Employee] FOR UPDATE AS IF UPDATE(EmployeeID) BEGIN UPDATE MCS_Address SET EmployeeID = 'i am stuck here; how to know the previous value? WHERE EmployeeID = ??? END </end>
ironically, PK in my table can be updateable as well.
Hello all. I have a table which is the exact replication of a different table. Now if an update takes place in the original table I want to copy that row into the new table without the update.I have this but I am not sure if it works.Create Trigger Content_Archive on content For Update As Insert Into content_audit Select * From DeletedI dont know if Updated exists so I am using Deleted. It is returning both rows (before and after update). And the insert should take place as soon as an update takes place in any field in the content table.
THREAD ------- THREAD_ID TOPIC_ID STATUS_ID THREAD THREAD_DATE NAME
I want to update STATUS_ID in TOPIC when I post a new THREAD. I guess the best would be to use a trigger? Don't know much how you write them so if someone please could help or point me in right direction. My plan is to always show the updated STATUS_ID in TOPIC while I have history in the THREAD TBL. I am using MS SQL 7.0
I am new to this and on my way to learning. I hope someone can help me with a trigger. I want to update status of one table when I insert a new threat in another. This is what I have come up with so far.

I HAVE TWO TABLES IN THE DATABSE T1 AND THE SECOND TABLE(T2) IS FOR AUDITING. THE STRUCTURE OF BOTH THE TABLES IS SIMILAR WITH ONE MORE COLUMN 'STATUS' IN THE T2. I HAVE ALREADY WRITTEN THE TRIGGERS FOR THE INSERT AND DELETE TRIGGERS SO THAT I CAN SAVE THE RECORD WITH STATUS OF 'NEW INSERT' OR 'DELETE' OR 'UPDATE' IN THE AUDIT TABLE(T2). HELP ME IN WRITING THE TRIGGER FOR UPDATE. MY PROBLEM IS I DON'T KNOW HOW TO STORE THE UPDATED COLUMNS VALUES INTO VARIABLES AND SO THAT I CAN STORE THE OLD VALUES INTO THE AUDIT TABLE(T2). I M USING SQL SERVER 6.5, SO WE CAN NOT USE COLUMNS_UPDATED() IN THE TRIGGER. PLEASE SUGGEST ME THE CODE SO THAT I CAN STORE THE OLD ROW IN THE TABLE(T1) TO TABLE (T2) WITH STATUS 'UPDATE' IN THE T2.
PLEASE SUGGEST ME..ITS URGENT.

I have an update trigger on a table on my transactional database that inserts a row of data into another database (audit database)for any modification made on the transactional database. So if i modify a row on tran db it will write the data modified as a new row in the audit db.
This works fine if I am updating only 1 row with each Update statement. However if I update more than 1 row (multiple rows) with the same Update statement, the update trigger only inserts the last row modified in the audit database. So I lose record of any other rows modified with the same update statement.
Is there a way by which i can change my Update trigger or something, so I get all the rows updated by 1 update statement inmy audit database???
these columns can allow nulls. What i whant to do with my trigger is do a after trigger and check after the load if a certain column is NULL place a X instead like a flag but only on the columns that are NULL how would i do this.
Is there a way I can get the old value of a specific field when using an update trigger? e.g. I want to use the condition 'If Update(Column) ' in odrer to create a logfile which stores the old and new value of a field. The new value can be get from a Select from Inserted table. Is there a way I can get the old value (before update) also??
I have created a table with the following columns Jobnumber varchar(20), weight real(4), freightcost money(8), trackingnumber vchar(50), comments varchar(2000) and voidid varchar(3)

I'm totally new to writing triggers, but managed to get a trigger to update a specific column (ufINCTcost) on change of another column (ufINCKm)
My problem is that the trigger performs this update on ALL rows, which makes it very slow. How can I get it to only update the column on the row where the change was made ?
My trigger looks as follows:
CREATE TRIGGER updateincidents ON [dbo].[_rtblIncidents] FOR UPDATE, INSERT AS IF UPDATE (ufINCKm) BEGIN UPDATE dbo._rtblIncidents SET ufINCTcost=dbo._rtblIncidents.ufINCKm+dbo._rtblInc idents.ufINCToll+dbo._rtblIncidents.ufINCParking+d bo._rtblIncidents.ufINCFlight+dbo._rtblIncidents.u fINCRental
The EMPLOYEE table holds all the basic stuff you would want to know about an employee and it contains a STORE_CODE attribute that points to the same attribute in the STORE table (to keep track of the store they work at). The STORE table has the STORE_CODE attribute, a NUM_EMP attribute that keeps track of the number of employees at that store, and some other information that is of no relevance to the question.
I've written the following TRIGGER to update the NUM_EMP attribute in STORE everytime a row is inserted or deleted from EMPLOYEE. It works fine for inserts and deletes but I am clueless as how to make it work for updates (an EMPLOYEE transfers to another store). I appreciate any feedback and please feel free to tell where I've gone wrong so far.
Thanks!

This is something I have limited experience on. I need to create an update trigger after insert on one table that updates a completely different production table. My development server is being re-done and I'm not sure when it will be back on line. I have created some audit tables using triggers but they a simple inserts into a new table.
I believe the trigger statement should look like this, any advice would be appreciated.
Thanks in advance.

I'm trying to write an update trigger on sql 2005 but having a few issues. Basically I have a table with say 10 records in there. When an update occurs on a record and I want the trigger to recognise this and place a flag of X in a column to mark it.
The trigger then copies the record marked with X into another table. In the source table where the flag is marked X it will then update it with a GetDate function.
Can someone advise what I'm doing stupidly wrong. I want a before update function. But I'm getting an error on the Before Syntax. Any advise/help appreciated

Hi All, I have a table with 5 rows that represent our production machines, that table is updated every 5 sec by our production software but not all the rows change values although the update runs on every row every time. Let me try to give an example:
I need a trigger to count my production, so I have created a temp table that writes a line every time the update is done, but the problem is that the update is done on every line not just on the ones that change value. How do I build a trigger to give me just the line that actualy changes the Prod_Count value?
Have a Rebate table which holds 2 types of records.
Code type 1 which is a customer_no and item_no combo Code Type 3 which is a Customer_type and item_no combo
When an order is entered have a trigger that reads the rebate table and if a match is found write the info that is in the Rebate table to an OrderRebate Table. It is possible there will be code type 1 and 3 that will match a certain customer number. But I want it to check for a code type 1 first, then if code type 1 does not exist then check for code type 3 and use it. So right now if both exist both get written.
