Hi,
I have a table by the name EmployeeDetails which has Empid, Empname and Date of birth. The empid column is set to auto increment.
Now I want to create a trigger in such a way that, whenever a new employee is added to that table it will display the empid of the newly added emloyee. I don't know how to do that.
I have a trigger written below to update another table when one table is updated. Basically it works when i update row after row from enterprise manager However when i use a script to update 10 or 20 rows then this trigger does not work. Can any one offer any suggestions on where this issue could be ?
DECLARE @iCount INT DECLARE @OldValue VARCHAR(255) DECLARE @NEWVALUE VARCHAR(255) DECLARE @EQNAME VARCHAR(255) DECLARE @EQTYPE VARCHAR(255) DECLARE @TEST VARCHAR(255) SET @NEWVALUE = 'INIT' IF (UPDATE(VALUE)) BEGIN SELECT @OldValue = deleted.value from deleted SELECT @NEWVALUE = inserted.VALUE,@EQNAME = inserted.EQ_NAME FROM inserted where inserted.attr = 'AreaCfg' IF (@@ROWCOUNT =0) BEGIN RETURN END IF ((@NEWVALUE = '') OR (@NEWVALUE is NULL)) BEGIN DELETE [TABLE-1] WHERE ENTITYID = @EQNAME RETURN END IF ((@NEWVALUE != @OldValue)) BEGIN SELECT @iCount = Count(*) FROM [TABLE-1] WHERE ENTITYID = @EQNAME IF (@iCount = 0) BEGIN -- No records are available so insert SELECT @EQTYPE = Typ FROM IP_EQ WHERE EQ_NAME = @EQNAME INSERT INTO [TABLE-1] (AlarmGroupId, EntityID, EntityType, OwnerId) VALUES (@NEWVALUE,@EQNAME,@EQTYPE,'Production Tracker') END IF (@iCount > 0) BEGIN -- No records are available so insert SELECT @EQTYPE = Typ FROM IP_EQ WHERE EQ_NAME = @EQNAME UPDATE [TABLE-1] SET ALARMGROUPID = @NEWVALUE WHERE ENTITYID = @EQNAME END END END
I need to trigger an email to user when a work order due date is approaching 1 day prior to the due date. Also I need to trigger when a user adds, delete, or modify work order to check on work order due.
HelloThe problem is need to find out the querry that has updated or insertedinto the table and in turn 'Triggered the Trigger'. I have the username, the machine name, Application name, but not the query. The updateis not desired and the application is doing it but the applicationbeing so large we are unable to pin-point the code which is doing thedammage.Pls help!RegardsAnubhav
i have set up a linked server. i can query the linked server in query analyzer and also do update/delete. but when i try to run the same query for linked server through insert trigger, i get following error: [OLE/DB provider returned message. [Microsoft][ODBC Sql Server Driver]Distributed transaction error].btw, i am using Sql server 2000, SP4. main server is windows 2003 server and linked server is windows xp pro.any suggestions will be appreciated.
Hey guys maybe you can help me out, been trying to figure this one out all day at work. I know how to use columns in a table to calculate another column in that same table. But I need to do some math on columns from a totally seperate table. Here is my scenario table 1 = stock table table 2 = Purchase order table in table 2 there are line items that have ordered quantities for parts that we have ordered in table 1 under each part number is a field for "quantity on order" I need to compute the "quantity on order" in table 1 by summing all of the quantities in table 2 where the partnumber = the partnumber from table 1
quantity on order (table 1) = sum of all quantities (table 2) where the part numbers match so for part number 516 i have this
In a very busy SQL2000 enterprise edition server with 8GB memory and 6 cpus sp3, I could not install a update trigger, unless all the appl connections are dropped. For this 24 HR running svr, could do it.
then I try to run a query as follows:
if exists (select rfABC.* A from rfABC inner join remoteSvr.XYZDB.dbo.vwIP L on A.Address = L.address and A.metro <> L.metro begin print ' ---- Yes metroID <> LAMetro, start job exec.... -----'
insert into tempCatchMetroIDGPRS select rfABC.*, metro, getdate() from rfABC inner join remoteSvr.XYZDB.dbo.vwIP L on rfABC.Address = L.address and rfABC.metro <> L.metro
update rfABC A set A.metro = L.metro from rfABC A inner join remoteSvr.XYZDB.dbo.vwIP L on A.Address = L.address and A.metro <> L.metro end else begin print ' ---- no metroID <> LAMetro, skip job exec.... -----' end
------------------------------ this query hang there could not execute. When I took off the if ... else condition, it run with like 0 second. Wondered if a 'busy' (which updates the IP address continueously) could cause above issues...
I'm trying to update (increment) Company.SumtotalLogons from CompanyUsers.NumberOfLogons where CompanyUsers.CompanyID = Company.CompanyID
I'd like to either write a formula (if it is even possible to fire a formula from one table update/insert to increment a field in another table), or a stored procedure that triggers an auto update/append into Company.SumTotalLogons
I know this is possible in access, so i'm wondering how to go about it in ms-sql?
I have a SQL Server database running on a local PC which will eventually be scaled up once everything is working.
The Database takes data from an Access database, then the SQL Server aggregates this data into several other tables.
I have used a trigger to run this in SQL Server, once a table in SQL Server is appended with a specific value.
I have tested the trigger to do a simple task, and this works.
I have tested the aggregation query which create 18 seperate tables as well. It takes around 25 minutes to run. These are huge tables
When I use Access to append the final value to start the SQL Server trigger it freezes and eventually times out. I assume this is because it is running the 25minute trigger, and Access has to wait until this is completed before it can proceed.
I was hoping it would trigger SQL Server to run the trigger, then Access could go off and do something else!
Need to parsing serverName and databaseName to run a dynamic query to get serverName and databaseName and employee_ID via a accountID parameter. ----------------------------- declare @stringSQL varchar(200) select @stringSQL= 'insert into temp1 select '+@AccountID+' accountID, employee_ID from ' + @serverName +'.dbo.'+@databaseName+'.tblEmployee where inactive=0' print @stringSQL_GetUserName exec (@stringSQL_GetUserName) select * from temp1 ------------------------------ above dynamic query works fine. Howevery, this should be run only under insertion event. When I put it in a proc to run within the insertion trigger or put the whole sql statement within the trigger:
1. when ran at a MSDE server MSDTC on server is unavailable.
2. when ran at a SQL2000 developer testing server with the distributed transaction coordinator on, the insertion a record in the isql/w hang there. Could not even to kill this query, and have to stop and restart the SQL server.
Then I just want to return the dynamic query result without 'insert into temp1 ', the result is still hang... Is there a way to let the insert trigger to run a dyanamic query which linked to around 10 servers?
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.

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

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 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?
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

There are two different Stored Procedures insert data into a table, is it possible to catch what stored procedure name was that trigged the trigger in the trigger?
Hi, I am trying to script a trigger on a table to accomplish the following... If a row is updated then the value in the 'date' column in that specific row would update to getDate(). I have never created a trigger before and finding it very difficult. Thank you very much in advance. Kind Regards, Sean.

I am looking for a INSERT trigger example, to achieve the following objective: I would like the trigger to be fired when a row gets inserted into a table. I want to retrive some value from the inserted row and use this value to insert a new row in table 2. Thanks
is it possible to run a trigger forever... whose work is to archive data from a table. or how can i do the operation to archive automatically ?Regards,Kamrul Hassan
Hi, Does anybody know how could I define a for each row trigger in sql Server 2005? What I need to do is before inserting in the table look through the rows to check wheter that value overlaps with the others. "Overlap" means that this value cannot be betweent the values fo two different columns, that is why I need to go through all the table. In case that was not possible, I propose the following, load the table in a dataset and check the constraint with a for loop despite of the performance could be decreased. Any suggestion?.
