If I have a trigger on a field in a table, and I update one record trigger fire properly. If I do a update to that same field on all records in the table the trigger does not fire. I the error in the trigger, or do I need to change my update statement?
View 2 RepliesHi to all Gurus,I am working with two tables, where in if a record is inserted in onetable an insert trigger fires and inserts relevant information for thatrecord in the second table. This works well within my applications.But it failed (or the trigger never fired)when we used the DTS Importwizard to insert new data into the table from an excel file.How can I overcome this situation? Any help is greatly appreciated.--Part-time BE

I'm aware that when bulk loading to a SQL 2005 database through an OLE DB Destination, you can enable the FIRE TRIGGERS option. Is this option available when your database target is SQL 2000? I can't find it in the Properties or other windows.
I have a Hits table that tracks the hits on the id of a Link table:
Hits:
int linkId (foreign Key to Link)
datetime dateCreated
varchar(50) ip
We recently had to merge Links from different systems that are implemented similarly. As a result, all the linkIds are now wrong in the Hits table because the ids all changed. I managed to track down all the old ids and their associated new ids and have it in a table that I call joined_links
joined_linksint oldId
int newId
So, how do I do a mass update of these linkIds in the Hits table in SQL? I know I could do it in .NET, but I'd rather not write an app to do that runs thousands of update statements. There's gotta be a way to do it something like this:
UPDATE Hits h SET h.linkId = (SELECT newId FROM joined_links WHERE oldId=h.linkId)
but obviously I don't have visibility of that linkId in the subselect... A Loop maybe?
This is a run of the mill application that moves orders from one table to another. There are 2 tables, Ordersummary & HstOrders.
Ordersummary has the following columns...
Identifier
FollowupId
OrderNumber
OrderReference
OrderReferenceOrigin
......
......
HstOrders has the following columns...
Identifier
OrderNumber
OrderReference
OrderType
......
......
The above two tables are bound by Identifier. After each month end, Orders are moved from Ordersummary to HstOrders.
Now my task is to update all rows in OrderSummary with the order details as seen in HSTOrders for ordertype = 'CREDIT'. OrderReferenceOrigin(in Ordersummary) should be updated with the value of Orderreference(from hstorders).
I have to update each row at a time & I need to write a cursor for mass updates where ordersummary.identifier = hstorders.identifier.
Can someone please help with in writing this update statement as I never wrote a cursor.
SQL Server 2000 on Win2k
I'm fairly new to SQL Server and I'm just wondering if it's possible to Update Statistice for all indexes somehow? I'm looking at the Update Statistics command and it doesn't seem to be possible.
The situation we have is a reporting DB that basically has all it's tables truncated and remade every night by some DTS jobs that import from another datasource and change the data and build some denormalzed tables etc.
Some of the large Insert operations go from taking 8 mins to taking several hours sometimes and updating the stats seems to fix the problem for a while. So I'd like to make sure the optimizer has all the latest stats for all tables.
Any other advice would be appreciated.
Cheers.
Hi,I need to update a field in about 20 records on a table. The table hasan update trigger (which updates the [lastedited] field whenever arecord is updated). As a result I'm getting an error: "Subqueryreturned more than 1 value.", and the update fails.Is there a way in the stored procedure to handle this issue?thanks for your help.Paul
View 2 Replies View RelatedHola!I'm currently building a site that uses an external database to store all the product details, and an internal database that will act as a cache so that we don't have to keep hitting the external database to retrieve the products every time a customer requests a list.What I need to do is retrieve all these products from External and insert them into Internal if they don't exist - if they do already exist then I have to update Internal with new prices, number in stock etc.I was wondering if there was a way to insert / update these products en-mass without looping through and building a new insert / update query for every product - there could be thousands at a time!Does anyone have any ideas or could you point me in the right direction?I'm thinking that because I need to check if the products exist in a different data store than the original source, I don't have a choice but to loop through them all.Cheers,G.
View 2 Replies View RelatedI have a trigger on UPDATE on a table. I'm running some maintenanceUPDATE and DELETE queries which I want the trigger to ignore but at thesame time I want other UPDATE queries that other users might be runningto keep triggering the trigger. Is there a SET statement perhaps thatI could set before my query? Or a clause in the UPDATE statement?This is on MSSQL 2000 server, on Win2k3
View 2 Replies View RelatedI've gotten conflicting info about this in the past so I thought I'd try to get clarification.
When a record is deleted, I'm sure it fires the delete trigger. Does it also fire the update trigger?
Thanks
I am trying to understand how to use instead of trigger using an update.
Here are a few things that I need clarified.
- When using an 'instead of Update' trigger is this replacing any other Update that is happening to the Table.
- Or, is the occurence of the trigger happening after the update?
- Also, I have seen some syntax where people use:
Update table
set field1 = inserted.field1
from deleted, inserted, table
where deleted.field1 = ....
Does this mean that when using the 'instead of' option it keeps track of
what is being deleted and what is being inserted by using such things as deleted.field1 or inserted.field1?
What I need to do is check that the previous value in a particular field is null before updating it. I don't want to update a particular field that already contains a value in it.
Thanks.
What would be the best way to handle different updates for a table, multiple triggers, or just one large triggger? I am not worried about their order of firing, just that they fire

Hello,
I would like to update foreign keys using triggers. At least thats what I think is the solution when having multiple references to a table in order to avoid the "cycles or multiple cascade paths" error message.
Anyway, here are three tables
Dentist table
dentist_id int identity (auto increment)
Patient table:
patient_id int identity (auto increment)
Appointment:
apointment_id int identity (auto increment)
id_dentist int FK to dentist_id
id_patient int FK to patient_id
I am gooling but cant find a way to make a trigger run only when the dentist_id from dentist table is updated. Also, is there a way to get the new id and old id somehow? I saw some posts with new.dentist_id and old.dentist_id but apparently is not for sql server.
Thank you.
SQL Server 2000 : I have a series of tables which all have the samestructure. When any of these tables are modified I need to syncrhoniseall of those modifications with one other table wich is a sort of mergeof the individual tables with one extra column.For most of these tables this is not a problem. The problem arriveswhen one of the tables has an ntext column which obviously can not beused in an update or insert trigger.Here's an example of one of them:CREATE TABLE tblImages(ID INT IDENTITY(1,1) PRIMARY KEY,Inventory nvarchar(8) NOT NULL,Coll nvarchar(8) NOT NULL,ImageFile nvarchar(128) NOT NULL,ImageNotes ntext NULL,TS timestamp NULLCONSTRAINT U_Images UNIQUE NONCLUSTERED (ItemCode, Inventory, Coll,ImageFile)I then had created an update trigger which looked like this:CREATE TRIGGER COLLNAME_UTRIGGER ON COLLNAME_ImagesFOR UPDATEASBEGINUPDATE tblImages SETInventory = inserted.Inventory,Coll = 'COLLNAME',ImageFile = inserted.ImageFileName,FROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Invventory = tblImages.Invventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileUPDATE tblImagesSET ImageNotes=inserted.NotesFROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Inventory= tblImages.Inventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileEND " & vbCrLf)The first update in my trigger, be it an update or insert trigger,works fine. It crashes with the "Cannot use text, ntext or imagecolumns in the 'inserted' or 'deleted' tables." error in the secondpart.I have read various messages through the Internet on this and severalof them reference using INSTEAD OF triggers and views. I have neverused those before as this is my first work with SQL 2000. None of theexamples of INSTEAD OF triggers I have seen yet use the actual insertedtables and I haven't quite understood how to use them correctly.Can someone help me with the basic syntax as this trigger is one ofseveral that I am going to have to get working.Thank you in advance for any help, assistance, suggestions or"direction pointing" you may provide.

Hi
There are 2 databases db1 and db2 on SQL server 7 with tables 1 and 2 respectively.
Both these tables have a field called Quantity. IF quantity gets updated in table 1 then that change should be immediately reflected in table2.
I though an update on table1 would serve the purpose but this trigger doesn't seem to be working however there are no errors during the syntax check.
The code for the trigger that i have used on table 1 is as below
CREATE TRIGGER [Qty_UPDATE] ON [Table1]
FOR UPDATE
AS
IF UPDATE (Qty)
BEGIN
UPDATE db2.dbo.table2
SET db2.dbo.table2.qty = qty
END
Please help
Thanks in advance
I have a table which when certain columns are updated, need a trigger to fire to update a next schedule date in that same table for that record. I can write the trigger, but my question for performance and efficiency is which approach would be better. Separate triggers fo the 8 columns, or a large trigger with an If to check if these columns are updated.
Thanks
am using FOR UPDATE triggers to audit a table that has 67 fields. Myproblem is that this slows down the system significantly. I havenarrowed down the problem to the size (Lines of code) that need to becompiled after the trigger has been fired. There is about 67 IFUpdate(fieldName) inside the trigger and a not very complex selectstatement inside the if followed by an insert to the audit table. WhenI leave only a few IF-s in the trigger and comment the rest of thecode performance increased dramatically. It seems like it is checkingevery single UPdate() statement. Assuming that this was slowing downdue to doing a select for every update i tried to do to seperateselects in the beginning from Deleted and Inserted and assigningcolumns name to specific variables and instead of doingif Update(fieldName) i didif @DelFieldName <> @InsFieldNamebeginINSERT INTO AUDITSELECT WHAT I NEEDENDThis did not improve performance. If you have any ideas on how to getaround this issue please let me know.Below is an example of what my triggers look like.------------------------------------Trigger 1 -- this was my original designCREATE trigger1 on TableFOR UPDATEASif update(field1)begininsert into AuditSELECT What I needENDif update(field2)begininsert into AuditSELECT What I needEND...... Repeated about 65 more timesif update(field67)insert into AuditSELECT What I needEND---------------------------------------------------------------------------Trigger 2 -- this is what i tried but did not improve performanceCREATE trigger2 on TableFOR UPDATEASDeclare @DelField1 varcharDeclare @DelField2 varchar....Declare @DelField67 varcharSelect@DelField1 = Field1,@DelField2 = Field2,....@DelField67 = Field67From DeletedDeclare @InsField1 varcharDeclare @InsField2 varchar....Declare @InsField67 varcharSelect@insField1 = Field1,@insField2 = Field2,....@InsField67 = Field67From Inserted-- I do not do if Update() but instead compare variablesif @DelField1 <> InsField1beginInsert into AUDITSELECT what I needendif @DelField2 <> InsField2beginInsert into AUDITSELECT what I needend............if @DelField67 <> InsField67beginInsert into AUDITSELECT what I needend----------------------------------------------IF you have any idea how to optimize this please let me know. Anyinput is greatly appreciated. I do not have a problem with triggersdoing what they are supposed to, they are very slow this is myconcern. The reason I gave you two examples is because i suspect ithas something to do with the enormouse amount of code inside thetrigger. both examples perform about the same whether i use the twohuge selects from the Inserted and Deleted or not.Thanks,Gent
View 1 Replies View RelatedHi all. I have this problem:
on insert in a new table a have to change one column before insert.
I wrote this trigger:

I recently moved a database from a SQL server 2005 box to new server running SQL server 2012. The update/insert triggers that were working on the tables to handle referential integrity checking are no longer working. Running the same database on SQL Server 2008 and everything works.
Here is one of the trigger that throws the error 44446
USE
[M2Data]
GO
/****** Object:
Trigger [dbo].[tblContacts_UTrig] Script Date: 3/11/2014 9:07:13 AM ******/
SET
ANSI_NULLS ON
[code]....
I have verified that there is a matching key in tblCompanys. Also, when I run a query to update tblContacts the error message appears but the update does take. If I try and edit the row directly by selecting edit top 200 rows - the error message appears and the update does NOT take.
These triggers were probably added to the database during an upsize from MS Access to SQL Server 7 way back. What am I missing - is it something in the syntax?
I want to be able to duplicate every single record that is inserted or updated in a particular table to another table, but not the delete. Is the best way to set-up a trigger? If so can anyone provide me with an example of how to do this? Also could you just duplicate certain columns in the row I would you have to do all columns?
Thanks for help.
I have a series of DTS packages.

Hi,
I have an user table with a single integer column. No indexes, no identities, nothing. I have to insert 600,000 rows via a client app. In tests, using BCP/Bulk Insert/DTS all runs OK (sub 3 seconds). However the app takes 5000 rows a second [considerably slower]. I can mimic this slow perfomance, within DTS, by removing the 'Fast Load' & 'Batch' options.
Question= why would the SQL insert run slower on one server and as fast as BCP/Bulk Insert/DTS on another? What can I check on the 'slow' running server? May there be a file version anomally ??
Version = SQL-2000 SP4
Any help much appreciated !!!
Does anyone know what the best way to do mass updates in SQL server is? I am currently using the methodology suggested in this article
http://www.tek-tips.com/faqs.cfm?fid=3141
But the article is assuming that once I update a field it is going to have a value that is NOT NULL. So I can loop through and update the rows that have a NOT NULL value. But my updated rows do contain NULL values, in this case what is the best way to go about this???

The company i work for changed names and all email addresses within the company have changed. While it was OK for a while they are no longer going to be forwarding email to the old addresses to the new ones. There are Tons of subscriptions and tons of email addresses that need to be changed to the new names.
If i could find the table with the TO: part of the subscription held in it i could just run an update on that field and it would be solved...however, i cannot find that field...
So,
Without going into every subscription in report manager, how can i change the email addresses? Any Suggestions?
Thanks in advance
Hi There
Most of the time my solutions consist of 1 or 2 packages and config files work well.
Now i have a solution with about 50 packages i have to move to QA.
However a config file has the package ID, so even thoug they use the same data source connection. I would have to create and change 50 config files.
Data sources are kept in the package xml , so if i copy all the packages to QA , and then change the Global Data Source connection, i still have to open each package maually and save it again.
Surely there must be an easy way to move all 50 packages and have the connection now point to QA. But config files and global data sources dont do the trick, what am i missing here ?
Thanx

I was wondering if anyone knows of any way, including third party tools, to replicate a design change on a table across many different databases. I have written an ASP script that allows me to copy multiple tables to multiple databases in one go but I need something that will allow me to replicate the design of a table by comparing source and destination tables. So far I have scripted most of it but I have no idea on which system table to get the identity information and it seems there must be an easier way!
Any help would be appreciated,
