I have triggers in place on a table that do various checks on data input. It is clear that because of these triggers I cannot do updates on multiple records in this table. When I do, I receive an error that "subquery returned more than one value." Is there anyway to work around this by temporarily turning off triggers or something else?
Many thanks for advice.
Is it possible to do an update on multiple records. I have fields CusOrderID and CusCreditAmt in table CusOrder; and fields CusOrderID and CreditAmt in table CusCredits. I would like to update the value in the CusCreditAmt field in CusOrder to equal the CreditAmt field in CusCredits where CusOrderID is the same in both tables.
I tried doing this in a stored procedure based on a View with an inner join between the 2 tables as follows:
Update View1
Set CusCreditAmt = CreditAmt
I received an error that the subquery returned more than one value. Is there anyway to do something like this and make it work?
Many thanks for any advice.
Hi...
I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...
this is my sproc...
ALTER PROCEDURE [dbo].[usp_Import_Plan]

)
SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN

So how do i do multiple inserts and updates using this stored procedure...

A server I'm working on has a very unique situation, where user tables and production tables reside on the same database. Users update / create tables or populates these tables, so it can't be a table-specific trigger. However, they give a new meaning to "kamikaze pilots" as it's not uncommon for them to "accidentally" update / insert / delete 500,000,000 + records in a single statement. I've tried educating them to use batching, but to no avail, so now I'm forced to stop these statements BEFORE they execute, based on rowcount, as they fill up the database log so quickly that it goes into recovery mode (It has a 200GB log file - insane, I know).
I recon the mosts transactions allowed should be 1,000,000 records in a single statement. Looking for database trigger to stop them from executing statements with large records?
Hello All
I am running a statment that updates 248 records in a table. That table has a trigger on update.
The First thing that the trigger does is to declare a number of variables and then set them using the values from the inserted and deleted temp tables.
This works fine when you are updating one row at a time but when you run a batch update it errors.
I believe this is because i am assuming that in a batch update a single row will be updated and then the trigger fired, then the next row and so on.
I now know that this is not the case. Is there a way of linking the 3 variables (see Below) so they all return information form a single row.
Declare@ApplicantId Int,
@NewStatus Int,
@OldStatus Int
Set @ApplicantId = (Select ApplicantID from Inserted)
Set @NewStatus = (Select StatusID from Inserted)
Set @OldStatus = (Select StatusID from Deleted)
Hope that makes sense
Thanks for any help.

Microsoft article Q142480 states "Triggers cannot be used to perform cascading updates and deletes if ForeignKey-to-PrimaryKey relationships have been extablished using SQL Server's DRI."
Does this mean that I cannot declare FK's in my scripts if I want to have triggers in the table? Do I just add a column in my table that will have a foreign key in it, but just not reference it in my script? Can someone clarify for me?
Thanks,
Nathan
This isn€™t an problem as such, it€™s more of a debate.
If a table needs a number of update triggers which do differing tasks, should these triggers be separated out or encapsulated into one all encompassing trigger. Speaking in terms of performance, it doesn€™t make much of an improvement doing either depending upon the tasks performed. I was wondering in terms of maintenance and best practice etc. My view is that if the triggers do totally differing tasks they should be a trigger each on their own.

I am trying to update a small subset of records of a given table (TRValue) using the records contained in ParcelTemp. The difficult part is getting the summation from a child file, TRGreen, for those same parcels contained in ParcelTemp. Instead of updating just a few records, all the records in TRValue are being updated, with the wrong values of course!
Basically, Update records in TRValue that are equal to:
Year = P.Year
Code = 'LG01'
Parcel = P.Parcel
with the summation of child records where the child records needed are:
Year = P.Year
Parcel = P.Parcel
Code:
UPDATE TRValue SET
Acres = SumAcres,
CurrentMarket = SumMarket,
CurrentTaxable = SumTaxable,
CurrentTaxAmt = ((SumTaxable * D.CertifiedRate) + 0.50)
FROM ParcelTemp P
[code]....
I am having trouble getting an Update call to actually update records. The select statement is a stored procedure which is uses inner joins to link to property tables. The update, insert, and delete commands were generated by Visual Studio and only affect the primary table. So, to provide a simple example, I have a customer table with UID, Name, and LanguageID and a seperate table with LanguageID and LanguageDescription. The stored procedure can be used to populate a datagrid with all results (this works). The stored procedure also populates an edit page with one UID (this works). After the edit is completed, I attempt to update the dataset, which only has one row at this time, which shows that it has been modified. The Update modifies 0 rows and raises no exceptions. Is this because the update, insert, and delete statements do not match up one-to-one with the dataset? If so, what are my choices?

In a situation where messages are coming in faster than they can be processed, at what point will service broker start up another queue_reader? Also, how do you prevent table locking if part of the processing of that message involves inserting or updating data in a table? We are experiencing this problem because of the high number of messages coming through, and I'm not sure what the best solution is - does service broker have some built-in support for preventing contention on a table when multiple readers are running? Or maybe a pattern that can be used to get around it?

Hello,
I am working on a web app and am at a point where I have multiple rows in my GUI that need to be sent to and saved in SQL Server when the user presses Save. We want to pass the rows to a working table and the do a begin tran, move rows from working table to permanent tables with set processing, commit tran. The debate we are having is how to get the data to the work table. We can do individual inserts to the work table 1 round trip for each row (could be 100's of rows) or concatenate all rows into 1 long (up to 8K at a time) string and make one call sending the long string and then parse it into the work table in SQL Server. Trying to consider network usage and overhead by sending many short items vs 1 long item and cpu overhead for many inserts vs string manipulation and parsing. Suggestions?
Thanks you
Jeff
I have a table that is increasing quite largely each day. By now, I have average 300 million of records over 2.5 years. Before we received our new interface, the data we received was aggregated and thus not that big.The problem is that the table is so huge that I cannot use the Slowly Changing Component. I was thinking about making a temp table where I load the incremental data before I load it into the final data mart table.Based on this temporary table I use a script to compare the temp data with the already existing data in the data mart. However, this requires a compare of each records (300 mil records).
View 3 Replies View RelatedWriting this code using a CTE or any other method which do not use a table variable or a temp table as the users do not permissions to run this code from the application because of their roles which are required for creating and dropping the temp tables.

Hi i am getting a weekly transaction file which has two columns trans code and trans date to indicate whether the record is changed, added or modified . and the monthly master file contains blank in these two fields.
How do i update the row coming from the transaction file in the tables which contain the rows from the master file .
to better explain the example is
Master File
ID Name AGE Salary Transcode TransDate
2 dev 27 2777
Transaction File indicating change
ID Name AGE Salary Transcode TransDate
2 dev 27 24444 C 08072007
the ouput should be
2 dev 27 24444 C 08072007
replacing the existing row in the table(updating the whole row)
i have 50 columns in my table and based on the two fields i should replace the rows exisiting in table and if ID doesnot match exist just add them as a new row.
what transformation should i use .... to replace all the columns which have matching ID in table to the current record from trans file and if there doesnt exist matching id just add them as new row.
Thanks...
Hi,
I have few tables. I want to identify the RECORDS for a table which has been created/modified for a particular date and time. I don't want to write a trigger to capture the event for add/update.
Is there any system table which track for date and time using stored procedure each individual records which has been last updated or newly created records??
Note : The application already created without lastModified date and each table... so, we don't want to modify the application or db.
Database : SQL Server 2000 sp4
thanks in advance.
I am a total newbie to SQL Server, but have a good idea about how things operate..
I have a "job" that runs multiple (10) update queries for me in different tables.
Can I create a stored procedure to do these so that I can make one call to them?
If not, how can I call the job to start external to MS SQL?
Is there a way to update all of the records in a table all at once using the results of a select of a different table's data?
For example.
There are two tables, each have a primary index of catnum. One table (invoice_items) contains the line items (catnum) of customer invoices. The other table (sales_history) is a sales history table. I want to select all data from the invoice_items and sum the sales for various time periods (sales_0to30days, sales_31to60days, etc.) I then want to update the sales_history table which has columns: catnum, sales_0to30, sales_31to60, etc.). I want to run this daily to update all records.
Any help would be appreciated. Many thanks.
Using SQL2000, is there another way of optimizing the original query below.TIA,BobUpdate Transactionset field1 = (select (sum(tax)-sum(credit))/sum(credit) from tblOrder wheretblOrder.id = Transaction.id),field2 = (select avg(price) from tblOrder where tblOrder.id =Transaction.id),field3 = (select min(cost) from tblOrder where tblOrder.id = Transaction.id)etc..(there are six additional updates)Is this a quicker way:Update TransactionSET field1 = (sum(tax)-sum(credit))/sum(credit) , field2 = avg(price) ,field3 = min(cost) , etc.....FROM tblOrderWHERE tblOrder.id = Transaction.id

I have a table A that has related records in table B. I need to run an update to concatonate certian values in table B into a single value in table A.
Since an UPDATE can't update the same row twice, is there any way I can do this other than use a Cursor?
Hey, I have couple of triggers to one of the tables. It is failing if I update multiple records at the same time from the stored procedure.
UPDATE
table1
SET
col1 = 0
WHERE col2 between 10 and 20
Error I am getting is :
Server: Msg 512, Level 16, State 1, Procedure t_thickupdate, Line 12
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.
What is the best possible way to make it work? Thank you.
I was able to catch one update but not multiple updates or batch updates done to the table. I know the updated records are residing in inserted and deleted tables. Without using cursors, how can i read and compare all the rows in these two tables?

I wrote a trigger that works fine when I insert record by record in the DB.
However, when I run a Stored Proc to insert a bunch of records at the same time, the trigger only works for the last record.
Anyone has a clue or a possible solution.
The trigger is well tested and works fine.

View 2 Replies View RelatedWhat 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
View 1 Replies View RelatedI am new to trigger and I have following question.
I have two tables: "Customer" & "AccountDetails". "Customer" stored customer's personal information, so one customer will be at one row. "AccountDetails" stored all the accounts information which tie to each customer, so there will be multiple rows for a customer since one customer can have mulitple accounts.
Right now I have a updated trigger on "AccountDetails" table. When there is an updated to this table, it will insert some data to another "CustLog" table for logging when customer does the updates. Let's say Customer "A" has 5 accounts. When "A" updates his accounts' information, all 5 rows will be updated, triggers will be called 5 times, and 5 insert rows will be added to "CustLog". Is that any way to keep track those 5 updated on "AccountDetails" are referred to the same customer (by customer ID or so) so that it will only run the trigger once instead of 5 times?
I hope I make it clear and please help me on this! :o
I have a question regarding Triggers.
Lets say I want to create a trigger for Insert, Update and Delete action. For each action I do different things.
Now I can create a single trigger for Insert, delete and update, and using counts for inserted and deleted table, take the action appropriately.
Or I can create three different triggers each for Insrt, update and delete.
Which option is better for performance?
Thanks
