CREATE trigger trUpdateGEOData
on dbo.BK_Machine
after insert, update
as
updateBK_Machine
setBK_Machine.LOC_Street = GEO_Postcode.STraatID,
BK_Machine.Loc_City = GEO_Postcode.PlaatsID
fromBK_Machine
inner join GEO_Postcode on BK_Machine.loc_postalcode = GEO_Postcode.postcode
and BK_Machine.LOC_Doornumber >= GEO_Postcode.van
and BK_Machine.LOC_Doornumber <= GEO_Postcode.tem
inner join inserted on BK_Machine.MachineID = Inserted.MachineID
Now the thing is that a machine not neccesarily needs a location which mean that if postalcode or doornumber is NULL this trigger should clear the street and city columns.
I'm new to sql server (2000) and I have to make some trigger before it will be too late :( I don't have much time to learn it right now. but I'll defiantly do this some time.
I have 2 tables. tbl_A and tbl_B . in tbl_A I have a field named 'money' and another field 'name' .I need to make a trigger that will run whenever the money field updated. the update should be like that: 10% of the money that are in the update statement goes to every row in tbl_A where name='<name that used in update query>'. in addition, the 10% and the name goes to tbl_B
Does anyone have code for a trigger that when the user deletes the record trigger it to insert into another table? Thanks in advance and appreciate your help!
Hello, It is rare that I have a user for Triggers, but I have a special case. In a table named tbl_PaymhistCurrentWeek, I have a column called 'AcctCode'. This column will contain data that will be derived from another column called AcctCodeWithZeros. AcctCodeWithZeros contains an account code with leading zeros. The column AcctCode needs to contain the value in AcctCodeWithZeros, only without the leading zeros.
I tried to set up something in a Derived Column Transformation within SSIS, but I can't use PATINDEX.
Here is the latest version of the Trigger:
***************** CREATE TRIGGER [dbo].[tr_AcctCode] ON [dbo].[tbl_PaymhistCurrentWeek] FOR INSERT AS
BEGIN INSERT tbl_PaymhistCurrentWeek (AcctCode, Co, AccountNoWithZeros) SELECT id.SUBSTRING([AccountNoWithZeros], PATINDEX('%[^0]%', [AccountNoWithZeros]), 14)AS AcctCode, id.Co, id.AccountNoWithZeros FROM Inserted id END **************** The default for AcctCode is an empty string, which is all I get when I insert into the table. AcctCode will be part of a primary key, so I don't think I can set up AcctCode to be a calculated column. What am I doing wrong?
The DDL for the table is as follows: tbl_PaymhistCurrentWeek ( AcctCode varchar(10) Default ' ' Not Null, Co char(2) Not Null, AcctCodeWithZeros varchar(20) Null CONSTRAINT (PK_PaymhistCurrentWeek) Primary Key Clustered (AcctCode, Co) )
Is it possible to have a login that can access a table, which has an Update trigger on a column, and do some updating on another column but not have the trigger fire?
I cannot disable the Trigger. This db is on production and the trigger cannot be taken off. I also cannot bcp the data out and do the updating and bcp back in. The production table must remain as is, however I need to update some cols without the trigger firing.
I am fairly new to using triggers and stored procs in SQL Server and could use some help.
Scenario:
I have a table on SQL Server database running on a Windows server (of course) that contains information about articles. A second server in the shop is set up as a LAMP (Linux, Apache, MySQL, PHP) box. What I would like to do is any time the SQL server table is updated or a record is added, tables in MySQL would then be updated to reflect the changes on the first server. My thought is to try and do this with triggers and a stored proc.
Questions: 1) Assuming MySQL can be accessed through ODBC, can an ODBC connection be set up inside a stored proc or trigger, or would this have to be done through the Windows ODBC Data Sources tool in the control panel?
2) Can a Stored Proc be used in a trigger?
3) Can a Stored Proc call an outside function, such as an API call for third party software?
I have created a trigger ON a table AFTER Insert, Update staement. In the trigger's body I am making a call to a stored procedure. In the procedure, I want to know the Trigger invoked due to which event : insert or Update as I have to handle bith the cases differently. But I am not able to find out any SQL server function or property which can distinguish between INSERT and Update events of a trigger.

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.
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'
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;

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)
When a row gets modified and it invokes a trigger, we would like to beable to update the row that was modified inside the trigger. This is(basically) how we are doing it now:CREATE TRIGGER trTBL ON TBLFOR UPDATE, INSERT, DELETEasupdate TBLset fld = 'value'from inserted, TBLwhere inserted.id= TBL.id....This work fine but it seems like it could be optimized. Clearly we arehaving to scan the entire table again to update the row. But shouldn'tthe trigger already know which row invoked it. Do we have to scan thetable again for this row or is their some syntax that allows us toupdate the row that invoked the trigger. If not, why. It seems likethis would be a fairly common task. Thanks.
Salve, non riesco a disabilitare un trigger su sqlserver nč da queryanalyzer, nč da enterprise manager.In pratica tal cosa riuscivo a farla in Oracle con TOAD, mentre qui nonriesco.Mi interessa disattivarlo senza cancellarlo per poi riattivarlo al bisognosenza rilanciare lo script di creazione.Grazie a tuttiHi I need to disable a DB trigger and I'm not able to do this neither withquery analyzer, neither with enterprise manager.I remeber this job was quite simple using TOAd in Oracle.I'm interested in making it disabled not delete it, without run creationscript.Thanks a lot to everybody.
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,
Hi all in .net I've created an application that allows creation of triggers, i also want to allow the deletion of triggers. The trigger name is kept in a table, and apon deleting the record i want to use the field name to delete the trigger
I have the following Trigger
the error is at
DROP TRIGGER @DeleteTrigger
I'm guessing it dosen't like the trigger name being a variable instead of a static name how do i get around this?
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)

Hi all,I am trying to write a stored procedure, which has two insert statements.the first insert statement, is simple which inserts data into a table and returns the primary key for the new row added. using this primary key, i am writing another insert statement, which passes a list of elements which would be then entered into another table, with the primary key of the first table.Is this possible to do in a single stored procedure? I have implemented this using two different sp, but am wondering if it can be done other way?thanks for your help!

I'm trying to construct the following SQL statement but am missing something somewhere.
I get a syntax error with the 1st FROM highlighted.
If i construct a query out of the bit that works and then construct a query on that query then i can get it to work no problem but how to mimic that in SQL ? I can't simply view the SQL of the queries because the query names replace the SQL statements.

We are running Sql 6.5 sp5 on a Pentium II 350 Mhz with 512 Mb. RAM, 1 ScSi 4 Gb hd, one 8Gb ScSi hd and 2 IDE hd (13,6 Gb and 8Gb) computer running windows NT 4.0 sp 6 without any problems. Now have bought a new computer. The new one is a Pentium III 733 Mhz 512 Mb Ram with 2 ScSi ultra wide 2 18Gb each and one 40 Gb Ide Hd. We have installed windows NT 4.0 sp 6 and Sql 6.5 sp 5. We have restored our database to make some tests to it. The database is 7 Gb big. The results of our test are that the old computer is between 20% and 30% faster than the new one when doing sql instructions and using the database even knowing that the hd´s of the new computers are 4 times faster than the old ones.
Would you please give us any help or clue that would make the new computer go faster? We know that upgrading to sql 7 will work but we need first to make this computer work better with the 6.5. Thank you.
I often use DTS to move databases between the servers. When you choose "Transform" data and “Column Mappings and Transformation” window opens, the default option is “Append rows to destination table”. Question: Is there a way to change the default option to “Delete rows in destination table”, so I wouldn’t have to go thru the transformation of dozens of tables every time I move databases around.
P.S. I know that I can save DTS package with my settings and use it later. The problem is that every time it might be different database or objects might change. So, it is not a solution for me.
I have a client requirement. We are integrating two applications. So the problem is that, whenever some updates (meaning to say "create" , "delete" , "update") happens in the SQL DB Tables, i needed to track that data and send it to a different system.
What I have thought abt is that if SQL could generate a file with all the values deleted/updated/created in the DB, then I could take those values and do the needful. Please help me..
