I am new in sql server. I am using TSQL2012 database. I have added a new column in processedOrderCount in Hr.Employees table. And created a trigger on Sales.Orders table that whenever orderId is updated it automatically updated processedOrderCount in Hr.Employees. There is a problem that the orderId is the identity column I can't update it. How can we work with identity column? the code of my trigger is:
If Object_id ('Sales.trig_Calculate_OrderProcessed', 'tr') is not null
Drop Trigger Sales.trig_Calculate_OrderProcessed
go
Create Trigger Sales.trig_Calculate_OrderProcessed
ON Sales.Orders
when i alter non identity column to identity column using this Query alter table testid alter column test int identity(1,1) then i got this error message Msg 156, Level 15, State 1, Line 3 Incorrect syntax near the keyword 'identity'.
i got a little problem. when i insert values into a table a trigger is launched wich updates something in the table too.
CREATE TRIGGER T1 ON Tbl FOR INSERT AS BEGIN IF (UPPER(USER) <> 'CONVERSIE') BEGIN UPDATE Tbl SET Datum = GetDate(), User = USER, WHERE Tbl.ID= (SELECT ID FROM inserted) END END
the error i receive is this: 'can not update identity column id' (id being pk).
I need to populate a temporary holding table from a trigger. The contents of this table will be added to another table when the Trigger has completed processing. The id column of the temporary table will be added to the max value in the final table to create the record identifier. I used an identity field in the temporary table to accomplish this. My initial idea was to create a temp table in the code for the trigger then drop the temp table when each recursion is complete. However I got "cannot use Create table in Trigger". Then I tried to make temp table in stored proc called by trigger. Same message. Then made permanent "temp" table, and tried to Trucate table after each use. I got "Cannot use Trucate Table in Trigger". Finally I used delete from and DBCC Checkident to reseed identity. This worked in Query analyzer. I worked in VB project using ADO. However, I after deployment I was informed that VB project using RDS to make and update ADO recordsets was failing to run the trigger. After troubleshooting I was alerted that DBCC CheckIdent can only be run by table owner. Business rules prevent this. Therefore I would like to know if anyone knows any other way to reseed an identity, before I abandon this approach and start over.
I have to tables : Rank and Item Rank contains a FK named R_I_id which references Item's primary key named I_id, which is also an identity column.
I want the field R_I_id of table Rank to be updated with the value of Item's I_id when a new Item is inserted. So I wrote the following trigger :
CREATE TRIGGER [dbo].[trg_oninsertitem] ON [dbo].[Item] AFTER INSERT AS BEGIN SET NOCOUNT ON SET IMPLICIT_TRANSACTIONS OFF DECLARE @I_id INT SELECT @I_id = SCOPE_IDENTITY()
BEGIN TRANSACTION INSERT Rank(R_I_id) VALUES(@I_id) IF (@@ERROR <> 0) BEGIN PRINT 'error in trigger trg_oninsertitem' ROLLBACK TRANSACTION END COMMIT END
But when I insert a value in Item, I got the following message :
Msg 515, Level 16, State 2, Procedure trg_oninsertitem, Line 17 Cannot insert the value NULL into column 'R_T_id', table 'base.dbo.Rank'; column does not allow nulls. INSERT fails.
and I don't understand, because my trigger is fired after the value is inserted in table Item, so the field I_id should contain a new identity value, not NULL
In my database all columns have Identity Value as a PK.
Now today I check Index Fragmentation I saw that many cluster and Non cluster Index are avg.Fragmentation is around 99 % I thought that in Identity column record is always inserted at bottom so there is no fill factor assigned to it.
So in this case Do I need to set Fill factor for Cluster and Non Cluster Index?
If Yes Then For PK How much - 95 % or what? and same for Non cluster or It should around 85 to 90
My current proc updates(updates using joins of two or three tables) millions of records as per the condition provided for each department.
However, when the proc fails it writes to a ErrorTable, ERROR_MESSAGE(), ERROR_SEVERITY() and which department has failed.
Since the records are updated keeping the selected departments in loop, I get the department in a temp variable.Now, I was asked to log the specific record where the failure was occured.Something like log the identity column value or primary key value which record has failed.
I am writing an Instead of Insert trigger. I would like to fire an error when inserting into an 'Identity' column. Since UPDATE([ColumnName]) always returns TRUE for insert statements, is there an easy/fast way around this? I don't want to use:Â
IF(EXISTS(SELECT [i].[AS_ID] FROM [inserted] [i] WHERE [i].[AS_ID] IS NULL)) here is my pseudo-code... CREATE VIEW [org].[Assets] WITH SCHEMABINDING
[Code] .....
-- How does this statement need to be written to throw the error? --UPDATE([AS_ID]) always returns TRUE
IF(UPDATE([AS_ID])) RAISERROR('INSERT into the anchor identity column ''AS_ID'' is not allowed.', 16, 1) WITH NOWAIT;
-- Is there a faster/better method than this? IF(EXISTS(SELECT [i].[AS_ID] FROM [inserted] [i] WHERE [i].[AS_ID] IS NOT NULL)) RAISERROR('INSERT into the anchor identity column ''AS_ID'' is not allowed.', 16, 1) WITH NOWAIT;
-- Do Stuff END;
-- Should error for inserting into [AS_ID] field (which is an identity field) INSERT INTO [org].[Assets]([AS_ID], [Tag], [Name]) VALUES(1, 'f451', 'Paper burns'), (2, 'k505.928', 'Paper burns in Chemistry');
-- No error should occur INSERT INTO [org].[Assets]([Tag], [Name]) VALUES('f451', 'Paper burns'), ('k505.928', 'Paper burns in Chemistry');
We have to encrypt one of the SQL Server column data at the database level, we don’t want to modify the application programs, because we use ERP application and we don’t want to reapply our customization very few months, so we are looking for an option  to encrypt and decrypt the column level data value using trigger/procedure/function,  I used instead of trigger on that table to encrypt and decrypt the values but it is not working, we want only one user(Application Service account) have an ability to encrypt and decrypt the data, not for any other id.. I read somewhere we cannot automatically encrypt/decrypt the column value using trigger, is that true...
I need a trigger to know who and when a char(1) column is changed. Â Would like to write the audit trail to its own table I can query and record before and after values.
DDL:
CREATE TABLE [dbo].[Test]( [Customer] [varchar](12) NULL, [Active] [char](1) NULL DEFAULT ('N') --Must use char 1 b/c more than 2 possible values )
Insert into Test (Customer, Active) Values ('Acme','Y')..I want trigger to tell me whowhenwhere this value was changed. Â If using sql auth capture client windows id if possible and write to audit table Update Test set Active = 'N'
Hi, I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time. thanks. varun
I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint
I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
Hi, I have a problem with a instead of Trigger. The Trigger's target is a view. When the Trigger is called during a query insert I must store the data inside two tables. The tables are related with each other by the primary key. So I must: a. Insert the data in the first table. b. Get the value of the Identity c. Insert the data in the second table. But I have a problem: the value returned of the query "SELECT ID FROM FIRST_TABLE WHERE ID = SCOPE_IDENTITY()" is null. I'm sure that the first insert query is executed. Where is the error?
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is : Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be created where the referencing column 'child_table.child_id' is an identity column.
Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time. What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have a problem with an existing stored procedure that is used to insert a new entry to a table (using an Insert statement).
I have been using the @@Identity global variable to return the identity column (id column) back to the calling routine. This has worked fine for years until recently an ‘after insert Trigger’ has been added to the table being updated.
Now the @@Identity is returning the identity value of the trigger that was called instead of the original table insert.
Does anyone know how I can code around this issue (without using a select statement within my stored proc, as these have been known to cause locks in the past).
I would like to use sequences and triggers to update table identity field with int value from sequence via before insert trigger. I'm searching on google for a few days and there are no same or identical article about this subject.
Is there any sample how to create table with column Id, Name, Comment and sequence (for generate int numbers for Int field in table) and trigger which will fired before insert and check is inserted Id is NULL and update this field from sequence or nothing if id is set up.
Hello; My Memebership table has Guid column as Primary key. But I would like to add Auto numbering Identity column to this table. Is this idea OK or it will bring some problems? Thank you in advance for your help
Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column. This column is a key field to othertables, so I want to keep the row numbers that are allready inserted.From the Query Analyzer, how do I do this?Thanks in advance!Regards,Gunnar VøyenliEDB-konsulent asNORWAY
I have a problem described as follows: I have a table with one instead of insert trigger:
create table TMessage (ID int identity(1,1), dscp varchar(50)) GO Alter trigger tr_tmessage on tmessage instead of insert as --Set NoCount On insert into tmessage
[code]....
When I execute P1 it returns 0 for Id field of @T1.
How can I get the Identity in this case?
PS: I can not use Ident_Current or @@identity as the table insertion hit is very high and can be done concurrently.Also there are some more insertion into different tables in the trigger code, so can not use @@identity either.
I am designing a database. I want to define a automatic sequence on a table primary key field. what is the best solution for it?I know I can enable identity property for a field, but it has some problems ( for example its seed jumps on restart and unsuccessful events).I also can use some calculated sequences. for example I can calculate max of the filed values and after incrementing use it as key for new inserted record.
I'm trying to insert records into "holding" table and write back identity column value (Entry_Key) to the original table. So my setup is I have two tables; tblEWPBulk and tbleFormsUploadEWP. Users will enter records into tblEWPBulk and use BatchID to group records, once batch entry has been completed (usually less than 30 records) user will click on UploadAll button and insert records (not all fields) into tbleFormsUploadEWP. One record in tblEWPBulk can be sent multiple times to the holding table but tblEWPBulk will need to have latest Entry_Key captured. Records are sent from holding table to DB2 z/VSE using SQL stored procedure and based on certain logic records are marked uploaded or certain error capture... that part works fine.
So for example I want to sendÂ
BatchID, AccountNumber, Period, ReceiveDate, AccountType, ReturnType, NetProfitOrLoss, TaxCredit FROM tblEWPBulk to the holding table and write back Entry_Key (identity column) back to the record in tblEWPBulk (field called UploadEntryKey). As I said one record could be sent to the holding table multiple times until uploaded or deleted and UploadEntryKey always needs to be updated so that when results are processed response from the DB2 can be inserted into table and presented to the user.
No foreign key relationship exists since records in the holding table get sent to the archive table and table is truncated and entry_key starting value reset back to 2000... just some DB2 restrictions.Â

I have a table of raw data where each column can be null. The thought was to create an identity key (1,1) and set as primary for each row. (name/ address / zip/country/joindate/spending) with surrogate key: "pkid".However other queries will not use this primary key. So for instance they may count the # of folks at a zip, select all names, addresses etc. The queries may order by join date, or select all the people that joined on a specific date.No other code would logically use the primary key (surrogate primary id key), therefore would it still have any performance benefits? at this time the table would have no clustured or nonclustured indexes or keys. I'm curious if there are millions of records.
