Trigger On Table Which Will Not Allow To Update Value 1 Into Column
Sep 25, 2014
I need to create trigger on table which will not allow to update value "1" into column and if tried to update.. then it should show error massage "Good To GO"
ID Name Roll
1 Ron 1
2 Jon 0
3 Nil 3
4 Par 1
if you try to update value "1" in Roll then it will through error
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.
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?
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
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. We'reworking on running a SQL trace but if anybody has any input, fireaway.Thanks!create table x(Id int,Account varchar(25),Info int)GOinsert into x values ( 1, 'Smith', 15);insert into x values ( 2, 'SmithX', 25);/* Update trigger tu_x for table x */create trigger tu_xon xfor updateasbegindeclare @TriggerRowCount intset @TriggerRowCount = @@ROWCOUNTif ( @TriggerRowCount = 0 )returnif ( @TriggerRowCount > 1 )beginraiserror( 'tu_x: @@ROWCOUNT[%d] Trigger does not handle @@ROWCOUNT[color=blue]> 1 !', 17, 127, @TriggerRowCount) with seterror, nowait[/color]returnendupdate xsetAccount = left( i.Account, 24) + 'X',Info = i.Infofrom deleted, inserted iwhere x.Account = left( deleted.Account, 24) + 'X'endupdate x set Account = 'Blair', Info = 999 where Account = 'Smith'
I 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?
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 am new to triggers and surely could use some help.
I can create a trigger to insert related records based on the main tables ID and insert that value into other related tables fine... but...
How do I create a trigger that can insert a record into one table for a columns given value and then insert a record into another table for another given value?
For instance: New row...
Table1, Column1 (PK) has a value of 101 Table1, Column2 has a value of 'Blue'.
// When a new row is created in Table1 and Column2 has a value of 'Blue'... I want to insert a new row into Table2 - with Table1 Column1's value.
// Now if Table1, Column2 has a value of 'Red' when the new row was created... I want to insert a new row into Table3 - with Table1 Column1's value. Not Table2
This has to be inserted into one or the other tables based on column2's value, not both. Then I want to populate the other related tables (Table4, Table5) with the regular insert statements based on Table1 Column1's value.
This (the conditional part above) has to work with an update to Table1 also. So if someone came back to that record and changed Column2's value from 'Blue' to 'Red', it would have to delete the appropriate record in Table2 and then insert the new row into Table3 and visa-versa.
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:
ALTER trigger [dbo].[antall_liter] on [dbo].[ProdTr] for insert as begin declare @liter as decimal(28,6)
I have an update trigger which fires from a transactiion table to update a parent record in another table. I am getting no errors, but also no update. Any help appreciated (see script below)

I have a trigger on an orders table. It checks against a patientmaster table to see if the sentflag is set to n or y. If it is "n" I need to push a record to a table on a separate db table. The user has permissions on the orders table. Without having the user be added and given permissions on the second db and table, what would be the best approach inside the trigger to handle this. I am using nt/sql security for this
Am in a small fix. my Trigger is updating my entire table records , i don't want that, i want to update a column in the record that is updated by my application using a trigger that tracks updates on that table.
Is there a way i can track the updated record on my table and then update a field in that record through my TRIGGER?
My database is MSSQLServer2005 Enterprise Edition..
Below is my code
CREATE TRIGGER [TR_Employee] ON [Test_1_1].[dbo].[Employee] For UPDATE Not For Replication AS BEGIN
Update Employee set Last_Changed = (select getDate())
I am new to triggers and need help on the following:
I have a hourly table that inserts new rows every hour but I need to either Insert or Update the daily table with the sum of the reading from the hourly table. If a row exist in the daily table with the date of the hourly table, then I need to update this row but if it doesn't exist, I need to insert this row.
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]. What I have so far is asfollows:TRIGGER #1:CREATE TRIGGER trgIns_Summary ON [CRPDTA].[F55MRKT119]FOR INSERTASBEGININSERT INTO CRPDTA.F55MRKT11select INS.MHAN8, INS.MHAC02, INS.MHMOT,case when INS.MHMOT='MAG' then 0 ELSE 1 end,case when INS.MHMOT='MAG' then 1 ELSE 0 end,'0' from INSERTED INSWHERE ins.mhan8 not in(select mdan8 from crpdta.f55MRKT11)ENDTRIGGER #2:CREATE TRIGGER trgUpd_Summary ON [CRPDTA].[F55MRKT119]FOR UpdateASBEGINUPDATE CRPDTA.F55MRKT11SET MDMAIL= case when INS.MHMOT='MAG' then 0+MDMAILwhen INS.MHMOT<>'MAG' then 1+MDMAIL end,MDMAG= case when INS.MHMOT='MAG' then 1+MDMAGwhen INS.MHMOT<>'MAG' then 0+MDMAG endfrom INSERTED INS JOIN CRPDTA.F55MRKT11on(ins.mhan8=mdan8)ENDFor instance if I do the following insert:INSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','AL4','0')thenINSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','MAG','0')This is what I expect in both tables:[CRPDTA.F55MRKT119] (2 Records)MHAN8 MHAC02 MHMOT MHUPMJ------ ------ ----- ------212131 VK4 AL4 0212131 VK4 MAG 0[CRPDTA.F55MRKT11] (1 Record)MDAN8 MDAC02 MDMOT MDMAIL MDMAG MDUPMJ----- ------ ----- ------ ----- ------212131 VK4 AL4 1 1 0The insert part works fine in that it iserts in both tables with thecorrect values. However it seems as if the Update protion is failingfor some reason. WHat I have tried so far is setting the trigger orderfor the update to run first and vice-versa, but still no luck. Anyhelp would be appreciated.
Hi,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
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
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
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?
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
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?
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
Here's my current code, if that track the problem in anyway:
Code:
ALTER TRIGGER UpdateTicketID ON Email Instead of INSERT AS IF ((Select charindex('{', [subject]) FROM Inserted) = 0) BEGIN INSERT INTO BadEmail ([Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLInk, SendTo, Cc, ContactID) Select [Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLink, SendTo, Cc, ContactID From Inserted END ELSE IF ((Select substring([subject], charindex('{', [subject])+1, (charindex('}', [subject]) - charindex('{', [subject]))-1) From Inserted) NOT In (Select TicketID From Ticket)) BEGIN INSERT INTO BadEmail ([Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLInk, SendTo, Cc, ContactID) Select [Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLink, SendTo, Cc, ContactID From Inserted END ELSE BEGIN INSERT INTO Email ([Subject], Sender, Body, ticketID, EntryID, LastModificationTime, AttachmentLink, SendTo, Cc, ContactID) Select [Subject] , Sender , Body , substring([subject], charindex('{', [subject])+1, (charindex('}', [subject]) - charindex('{', [subject]))-1) , EntryID , LastModificationTime , AttachmentLink , SendTo , Cc , ContactID From Inserted END
I'm new to this whole trigger 'thing', so forgive me if this question has been asked and answered a few times already.
I'm in the process of writing a trigger that will send an e-mail to an application admin when any table within a given database is altered (IE, a column is added or deleted). I can get the e-mail to fire off when that happens without any issue, but I'd like to be able to let the admin know which table was tweaked and what new column was added.
Is this a relatively easy thing to do and I'm just not finding the right built-in variable name, or does something more need to be done?
Hello,i have a table and if a record is inserted i will test a numeric valuein this table. If the this value is greather as 1 million, than anstatus column should be changed from 'A' to 'B'.Yes and sorry, this is a newbie question.On Oracle this work simple:create trigger myTrigger on tableXasbeginif :old.x 100000 then:new.y:='B'end if;end;ThanksMaik
I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.
This is my statement:
UPDATE [dbo].[sessions_teams] stc SET stc.[Talks] = fmt.found_talks_type FROM @Find_Missing_Talks fmt WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks) AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)
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.
Need to update one table with value of a column in another table plus a constant:
UPDATE TABLE_A SET TABLE_A.COLA=TABLE_B.COLB+'10' FROM TABLE_A INNER JOIN TABLE_B ON TABLE_A.COLA=TABLE_B.COLA WHERE TABLE_A.COLA=TABLE_B.COLA
The above statement works except the concatenated string has space between TABLE_B.COLB text and '10'. How to remove the space (4 characters) so that the string shows as one word 'TABLE_B.COLB10'?
