Hi,
I need to update a field in about 20 records on a table. The table has
an update trigger (which updates the [lastedited] field whenever a
record is updated). As a result I'm getting an error: "Subquery
returned more than 1 value.", and the update fails.
Is there a way in the stored procedure to handle this issue?
thanks for your help.

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.

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.
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 Replies View RelatedI 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?
Hola!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.

Hello
I've to write an trigger for the following action
When a entry is done in the table Adoscat79 having in the index field Statut_tiers the valeur 1 and a date in data_cloture for a customer xyz

statut_tiers to 1
and date_cloture to the same date as entered
the same action has to be done when an update is done and the valeur is set to 1 for the statut_tiers and a date entered in the field date_clture

I am trying to update one table when records are inserted in another table.
I have added the following trigger to the table “ProdTr” and every time a record is added I want to update the field “Qty3” in the table “ActInf” with a value from the inserted record.
My problem appears to be that I am unable to fill the variables with values, and I cannot understand why it isn’t working, my code is:

I currently have 2 tables as follows:CREATE TABLE [CRPDTA].[F55MRKT119](mhan8 int,mhac02 varchar(5),mhmot varchar(5),mhupmj int)GOCREATE TABLE [CRPDTA].[F55MRKT11](mdan8 int,mdac02 varchar(5),mdmot varchar(5),mdmail int,mdmag int,mdupmj int)What I would like to do is place a trigger on F55MRKT119 which willinsert records to the F55MRKT11 if they do not exist in that tablebased on the [mdan8] field. If the record does exist I would likeUpdate the corresponding record and increment either the [MDMAIL] orthe [MDMAG] based on the inserted [MHMOT].

View 1 Replies View RelatedHi,Does anyone know of a simple way to do this? I want to create aninsert trigger for a table and if the record already exists based onsome criteria, I want to update the table with the values that arepassed in via the insert trigger without having to use all the 'set'statements for each field (so if we add fields in the future I won'thave to update the trigger). In other words, I want the trigger codeto look something like this:if exists (select * from TableA where Fld1 = inserted.Fld1) then//don't do insert, do an update instead (would i want to rollback here?and will I have access to the 'inserted' table still?)Update TableASet TableA.<all the fields> = Inserted.<all the fields>where Fld1 = inserted.Fld1end ifAny help or ideas would be appreciated.Thanks,Teresa

I have created a simple trigger that updates a table called documents in my database. When a row has been inserted it will change the field form_type to 'cabinet A' if a document_type is equal to 'form'.
Im fairly new to triggers and Im uncertain whether this trigger is updating the whole table or the new row? I only want the new row to be updated as the table is fairly large.
create trigger file_documents
on documents_table
after insert
as
begin
update documents_table
set cabinet = 'Cabinet A'
where document_type = 'FORM' end
Setup:
Using SQL 2005
TableA
ID INT PK
Name VARCHAR
RefID FK
ID Name RefID
1 Test1 <NULL>
2 Test1a 1
3 Test1b 1
4 Test1b1 3
5 Test1b1a 4
CREATE TRIGGER Update_ID
ON TableA INSTEAD OF UPDATE
AS
IF UPDATE(ID)
BEGIN
DECLARE @old_ID INT
DECLARE @new_ID INT
SELECT @old_ID = ID FROM DELETED
SELECT @new_ID = ID FROM INSERTED
UPDATE TableA
SET ID = @new_ID
WHERE ID = @old_ID
UPDATE TableA
SET RefID = @new_ID
WHERE RefID = @old_ID
END
SPROC:
UPDATE TableA
SET ID=6
WHERE ID=2
RefID is the FK to ID
ID is also the PK to another table and has the relationship use cascading Delete and Update.
Problem:
"The UPDATE statement conflicted with the SAME TABLE REFERENCE constraint"
This is referring to the first UPDATE of the Trigger.
It was my understanding that Instead Of checks the constraints after it is all done yet it errs with the first Trigger UPDATE.
I was expecting to overcome the self-reference constraint issue by using Instead Of and with the first Trigger UPDATE, change the ID(PK) and then change the RefID(FK) with the second Trigger UPDATE.
Once that was done, it should have not had any constraint problems. Thoughts?
Thanks, Nathan
Say you have an existing populated SQL 2005 database, with 700+ tables, and you want to just change the order of the columns inside every table. Short of manually building conversion scripts, anyone know an automated way to do this? I was thinking thru ways to do them all in one shot, and have tools like Erwin and DbGhost that could be used also. Basically moving some standard audit columns from the end of the tables to just after the PK columns.
Thanks, Bruce
I have a Trigger Instead of Update.
When I Update my table, the trigger runs correctly but my table never is updated.
Hi ,
I have 2 tables (Dept and Emp)
The columns in table Dept are Deptno and Deptname. Deptno is bigint and it is primary key. In Emp table, columns are Empno(PK) ,EmpName and Deptno(foreign key referring to Dept)
To Insert or Update record in Emp through application, value of Deptno is coming as 0(Zero). I want the value of Deptno to be inserted or updated as null if the value is Zero (0). How to do this in sql server 2005 by using trigger on table Emp
Thanks in advance

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?
any ideas?
Hello again,
I'm hoping someone can help with with a task I've been given. I need to write a trigger which will act effectively as a method of automatically distributing of incoming call ticket records. See DDL below for creation of the Assignment table, which holds information on the call ticket workload.
Code Snippet
CREATE TABLE #Assignment
(CallID INT IDENTITY(1500,1) PRIMARY KEY,
AssignmentGroup VARCHAR(25),
Assignee VARCHAR(25)
)
GO
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Jim Smith')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Donald Duck')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Donald Duck')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Mickey Mouse')
GO
SELECT COUNT(CallID) AS [Total Calls], AssignmentGroup, Assignee
FROM #Assignment
GROUP BY AssignmentGroup, Assignee
ORDER BY COUNT(CallID) DESC , AssignmentGroup, Assignee
What I need to do is write a trigger for on INSERT to automatically update the Assignee column with the name of the person who currently has the least active calls. For example, using the data above, the next PC Support call will go to Mickey Mouse, and the next two Service Desk calls will go to Jim Smith.
So, the logic for the trigger would be
UPDATE #Assignment
SET Assignee = (SELECT Assignee FROM #Assignment WHERE COUNT(CallID) = MIN(COUNT(CallID))
But that's only the logic, and obviously it doesn't work with the syntax being nothing like correct.
Does any one have an idea or pointers as to how I should go about this?
Grateful for any advice, thanks
matt
FYI: I'm using SQL2005 on a windows 2003 server.
So, I've written an Instead of Trigger to update a foreign key field based on information in another field of the same record.
To add some error handling to the process I updated the Trigger to insert any records that don't have legitimate foreign keys into a second table.
This process works great when I test it by just adding a record using the table view in the SQL Management Studio or through a query run in the query browser.
However, when a record is added via an ODBC connection I get foreign key constraint errors and records are not added to the second table. If the foreign key is legit the record is added and the part of trigger that updates that keyed field executes just fine.
Is anyone aware of this issue? Is there a way around it?
I found the following MSKB article but I'm not sure if it applies to my situation:
http://support.microsoft.com/kb/304096

ALTER TRIGGER UpdateTicketID

INSERT INTO

Select

I have a situation where I have Table A, Table B.
View C is created by joining table A and table B.
I have written a instead of trigger D on view C.
I do not insert/update/delete on the view directly.
For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.
And I am unable to see this trigger work on the view if any insert/update occurs on base table level.
Trigger is working only if any operation is done directly on the view.
We have a database on a 2005 box, which we need to keep in sync with one on a 2014 box (until we can turn off the one on 2005). The 2005 database is still being updated with changes that must be applied to the 2014 database, given the nature of the data (medical documents) we need to ensure updates are applied to the 2014 database in very near real time (these changes are - for example - statuses, not the documents themselves).
Cunning plan #1, ulgy - not at all a fan of triggers - but use an after update trigger to run a sp on the remote box via a linked server in this format, with a SQL Server login for the linked server with permissions to EXEC the remote proc.
CREATE TRIGGER [dbo].[SourceUpdate] ON [dbo].[SourceTable]
AFTER UPDATE
AS
SET XACT_ABORT ON;
SET NOCOUNT ON;
IF UPDATE(ColumnName)
[Code] ....
However, while the sp can be run against the linked server as a standalone query OK, when running it in a trigger it's throwing
OLE DB provider "SQLNCLI" for linked server "WIBBLE" returned message "The transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Procedure TheAfterUpdateTrigger, Line 19
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "WIBBLE" was unable to begin a distributed transaction.
Whether it actually possible to call a proc on a remote box via a trigger and if so what additional hoops need to be jumped through (like I said, it'll run OK called via SSMS)?
Hi,
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
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname

Hi,
I'm working with MRS and I've got a table with a lot of entries. For each value in the table I'm trying to get the text colour to be set to 'red' when the value of the cell is less than 0. Otherwise remain black.
I can do this by setting the colour property cell by cell. But I have a lot of cells in the table. Is there a way to set the statement to apply to ALL cells in the table?
Basically I'm asking if there is a way to set the property in bulk instead of going through tediously cell by cell.
Any help would be much appreciated. Thanks!
Hi guys, may I know is it possible to create an update trigger like this ? Assuming there are two database, database A and database B and both are having same tables called 'Payments' table. I would like to update the Payments records on database A automatically after Payments records on database B had been updated. I can't use replication because both tables might having different records and some records are the same. Hope can get any assistance here, thank you.
