I have a basic knowledge on trigger coding but I am not sure how to code the trigger to copy data (from another table) that keyed off field A (of tableA) only if fieldB (of tableA)=999
Trigger on TableA: field A, field B (only if fieldB=999)
TableB: colA, colB,colC,colD, colE, colF
TableC: dfC, dfD
if TableA rows updated and meet the condition(fieldB=999) , copy colC, colD fo tableC WHERE colA of (tableB) = fieldA (of tableA)
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER abc
ON TableA AFTER INSERT,UPDATE
AS
BEGIN
SET NOCOUNT ON;Insert TableC (colC, colD)Select tableA.fieldA From Inserted tableA Inner Join TableB ON tableB.colA = tableA.fieldAWhere tableA.fieldB = 999
END
GO
is this correctly coded? If not please show me your correction.
This Continues a question from previous trigger advice question
Is there no global way to grab all columns for a row I tried using * like you would with select. But it failed. I have been unable to find an example or command that shows if this possible. The all show you have to type out your fields and in my case that would take time. The below does not work. Does anyone have a advice on this, Thanx.
INSERT INTO Archive () Select i.*
This section of the trigger does work. SET IDENTITY_INSERT Archive ON INSERT INTO Archive (grid, name, address, state, zip, arc) SELECT i.grid, i.name, i.address, i.state, i.zip, i.arc fromInserted i inner join deleted d on d.grid = i.grid inner join [Active] a on a.grid = i.grid WHERE i.arc = 1 and isNull(d.arc,0) != 1
I€™ve developed a trigger for SQL 2000 that works great in my test environment, but is a bit inconsistent in my production environment. The goal of this trigger is to find and update the row that was just entered in the OCNTACT2 table. It takes the highest integer value from CONTACT2.UPRONUM (yes, it€™s an nvarchar field), increments it by one, then updates the CONTACT2.UPRONUM field for the newly inserted row. Does anyone see anything wrong with this trigger? Thank you for reading. CREATE TRIGGER Update_UPRONUM_For_Webgrabber ON CONTACT2 AFTER INSERT AS BEGIN SET ROWCOUNT 1 UPDATE CONTACT2 SET CONTACT2.UPRONUM = CAST(C.tempColumn AS int) + 1 FROM CONTACT2 CROSS JOIN (Select top 1 cast(upronum as int) as tempColumn from CONTACT2 AS CONTACT2_1 WHERE (UPRONUM NOT LIKE '%[,]%') AND (UPRONUM NOT LIKE '%[a-z]%') AND (UPRONUM NOT LIKE '%[A-Z]%') order by cast(upronum as int) desc) AS C WHERE (CONTACT2.UPRONUM IS NULL OR CONTACT2.UPRONUM = '') AND (CONTACT2.UCOMPBY = 'WEB') AND (CONTACT2.UWEBDATE > '12/13/2007') SET ROWCOUNT 0 END

I am trying to create a trigger so every time a entry is made on a table, and the Colum1 is 'entry', it starts a job. But the users running the inserts do not have permission to Start jobs so I need to make it run as a super user. Where do i put the syntax in here? I Have tried Execute as login 'superuser' before the exec statement but it errors on the principal not being valid
I keep receiving the following error whenever I try and call this function to update my database.
The code was working before, all I added was an extra field to update.

Forgive the noob question, but i'm still learning SQL everyday and was wondering which of the following is faster? I'm just gonna post parts of the SELECT statement that i've made changes to:
INNER JOIN Facilities f ON e.Facility = f.FacilityID AND f.Name = @FacilityName
OR
WHERE f.Name = @FacilityName
My question is whether or not the query runs faster if i put the condition within the JOIN line as opposed to putting in the WHERE line? Both ways seems to return the same results but the time difference between methods is staggering? Putting the condition within the JOIN line makes the query run about 3 times faster?
Again, forgive my lack of understanding, but could someone agree or disagree and give me the cliff-notes version of why or why not?

how can you convert it to sql syntax
I need to have a nested If statment which I can't do in sql (in sql I have to have select and from Together for example ( I can't do this in sql): select ID, FName, LName if(SUBSTRING(FirstName, 1, 4)= 'Mike') Begin Replace(FirstNam,'Mike','MikeTest') if(SUBSTRING(LastName, 1, 4)= 'Kong') Begin Replace(LastNam,'Kong,'KongTest') if(SUBSTRING(Address, 1, 4)= '1245') Begin ......... End End
end
Case Statement might be the solution but i could not do it.
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)
This is the error it gives me for my code and then it calls out line 102. Line 102 is my buildDD(sql, ddlPernames) When I comment out this line the error goes away, but what I don't get is this is the same way I build all of my dropdown boxes and they all work but this one.

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 nè da queryanalyzer, nè 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?

Hi, i am trying to write a mulitple sql statement. basically i have 5 fields to search:
User ID FirstName LastName Department Site i would like to search the records of the database with any of the fields above, so a user can specify a last name of "smith" and a department of "finance" which would return all the smiths in the finance department. or if a user enters "john" all the johns from any department or site would appear. How would the sql statement go like for this? and could i bind a tableadapter to a datagrid to view the results? Any help would be appreciated. Thank you.

Hi all, I'm trying to build a simple forum. I want to display a list containing the forum names and last post date and last post author. I can view the date, but can't figure out a way to see the author.

I am trying to create a view, but I am having trouble with the syntax (go figure!). It seems that as I reference more and more tables, my result set becomes smaller. For example, I want to return the state for all my customers then everything is fine, but when I want the state plus the site type (home, office, etc.) then I return fewer results. What is would be the correct syntax to use to return all the rows even if some of the columns have NULL?
SELECT TimeZone.LongZone, SiteMain.SiteNumber, SiteType.SiteTypeDescription FROM SiteType INNER JOIN TimeZone ON SiteType.id = TimeZone.id INNER JOIN SiteMain ON TimeZone.id = SiteMain.TimeZone AND SiteType.id = SiteMain.SiteType
