T-SQL (SS2K8) :: Update / Insert Trigger With Condition
May 15, 2014
I am currently in the process of writing an INSERT/UPDATE trigger in SQL 2012, the scenario is, I have a table called Quote, what I want to happen is when a record gets added to the table with a field called Approved, populated with a value or a record gets Updated and the Approved field gets populated I want the trigger to execute a stored procedure, passing through a value from a field called Account within the Quote table as a variable. I know I can achieve the action using one trigger "AFTER INSERT, UPDATE" but I am struggling on forming the rest of the trigger.
I currently have a AFTER UPDATE trigger that looks at a specific column being updated. It works great, but I am now needing to also capture the field data when it is initially created as well. Do I need to build a sperate FOR INSERT trigger to capture the initial column data when inserted, or is it possible to build it into my current AFTER UPDATE trigger?
Here is my current trigger: CREATE TRIGGER [dbo].[xResponsible_By] ON [dbo].[PARTS_REQUESTOR] AFTER UPDATE
I have an address table, and a log table will only record changes in it. So we wrote a after udpate trigger for it. In our case the trigger only need to record historical changes into the log table. so it only needs to be an after update trigger.The trigger works fine until a day we found out there are same addresses exist in the log table for the same student. so below is what I modified the trigger to. I tested, it seems working OK. Also would like to know do I need to use if not exists statement, or just use in the where not exists like what I did in the following code:
ALTER TRIGGER [dbo].[trg_stuPropertyAddressChangeLog] ON [dbo].[stuPropertyAddress] FOR UPDATE AS DECLARE @rc AS INT ;
Table A - data example Idno Entity Flag 1 1 y 2 1 n 3 1 y 4 1 y
Table B - data example Idno Entity 1 1 2 1 3 1
Table C - data example Idno Entity 4 1
I want to update the value flag in table A.Update flag from n to y if idno A in table B and and idno A not in table C, so from table A above, first record and 3rd record remain unchange but 2nd record, flag will be changed from n to y. 4th record where idno A not in table b and in Table C so flag will change from y to n. is it possible, or do i need to use the "fetch" method to compare record by record.
IF EXISTS ( SELECT * FROM empList WHERE (unit = 9)
) begin
update [dbo].[empList] set unit = CASE WHEN SELECT na,empID, unit FROM empList WHERE (empID IN (111, 222, 333, 555)) AND (unit = 9)) then '4' else t.fld1 end
I want to change Set clause of Update Statement dynamically based on some condition.
Basically i have 2 Update statments having same FROM clause and same JOIN clause.
Only diff is SET clause and 1 Where condition.
So i am trying to combine 2 Update statements into 1 and trying to avoid visit to same table twice.
Update t Set CASE **WHEN Isnull(td.IsPosted, 0) = 0 THEN t.AODYD = td.ODYD** *ELSE t.DAODYD = td.ODYD* END From #ReportData As t Join @CIR AS tmp On t.RowId = tmp.Max_RowId
I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.
since ten years perhpas the society has a database with some table (person, country, and so on)since last years , the project manager decides to create a new database with some new design because before some information was save in one table well, the problem is when we pass all application to the new model we've notice that some id are not the same !
sample :
table Language old model ------------------------- id frenchDescription english description ---------------------------------------- 3 Anglais English ..... ......
table Language new model
id frenchDescription english description ----------------------------------------- 5 Anglais English ..... .....
Alright , you can understand that the new model must be the same id => 3
Hi, Is it possible to group all my update/insert (one table) ? Cause I hope to have all the update/insert in one Trigger execution. I need to sum up some figures here. I am using ASP.NET 2.0, SQLOLEDB and SQL 2005. Please Help and Thank you.
I would like to update a record in a table when a record is added. The dilema is I want to update the record I am adding. I tried an insert trigger ( it doesn't fail, it just doesn't update) If I use the same syntax in TSQL after the record has been inserted it handles the update properly. SO I think the syntax is OK. I have the trigger below. The question is - Is there a way to do this? Thanks
CREATE TRIGGER transaction_ins_tr ON dbo.transactions FOR INSERT AS DECLARE @pat_id varchar(5), @location_name varchar(50), @account_id char(12), @tran_num int --get patient id SELECT @pat_id = patient_id FROM inserted select @account_id = account_id from dbo.patient pa where pa.patient_id = @pat_id --get location select @location_name = df_sitename from development..patient_ dp where dp.account_id = @account_id -- update trans location update dbo.transactions set df_sitename = @location_name where tran_num = @tran_num
Tbl1 inserts 1 record(with some fields populated) in tbl2. then I need get values from tbl3 to populate the rest of the fields in tbl2(update the record). tbl1 = tblallBag_data tbl2 = tblBag_data tbl3 = tblShipping_sched
I created a trigger in tbl1 to insert a record into tbl2 and it works fine.
CREATE TRIGGER trgtblBag_Data ON dbo.tbltblallBag_data FOR INSERT AS
INSERT INTO tblBag_data (work_ord_num, work_ord_line_num, bag_num, bag_scanned_by, bag_date_scanned, bag_quantity) SELECT work_ord_num, work_ord_line_num, bag_num, bag_scanned_by, bag_date_scanned, bag_quantity FROM inserted
How can I update tbl2? Should I create another trigger to update tbl2? Should I join the two tbls(tbl2 & tbl3) to find @work_ord_num = work_ord_num , @work_ord_line_num = work_ord_line_num
I have several tables that i need to add a trigger to. One such table is "Clusters". This table contains a column called ClusterFKey which should be the same value as the AutoID column in the Serverdata table (same db) and should be populated every time a record is added to the Clusters table. The value should be joined on the servername column's value in both the Serverdata and Clusters table.
So, when a record is added to Clusters, the ClusterFkey should equal the AutoID key in Serverdata where Clusters.servername = Serverdata.server and Clusters.ClusterFkey is null.
Hi!I wonder how to use conditions in the inserted table(in ainsert/update) trigger? The inserted table contain all the rows thathave been updated or inserted (for an update/insert trigger), but outof all these rows in inserted table, I only want the rows where aparticular field have been updated, for example if idkey have beenupdated it would be in inserted BUT I only want this row if the fieldamount have been updated. Can a use the UPDATE(column) some how? Anyideas?/Jenny
I would like to insert an update trigger which should achieve the following functionallity (as per trigger algorithm) but somehow it is not working. can you please help me since I am still green with SQL and programming, but I need to solve this before I can continue!

I have a table called drugs with a cost, date, and drugname field. I have a history table that I want to insert into anytime the fields are changed in the drugs table. I want to capture the old data along with the new cost. is that possible in a update trigger? What I have below doesn't like when it comes to setting the new cost
create trigger Updt_drugs on drugs for update as -- updates record with sql user and timestamp --created 1-12-02 tim cronin declare @newcost money begin set @newcost = select cost from inserted insert into drugsold ([oldcost],[cost],[cdate],[drug]) select [cost],@newcost,[cdate],[drug] from deleted dt end
I HAVE TWO TABLES IN THE DATABSE AND THE SECOND TALE SI FOR AUDITING. I WANT CREATE THE TRIGGER ON FIRST TABLE SO THAT I CAN PUT THE STATUS LIKE INSERT,UPDATE OR DELETE IN THE STATUS COLUMN IN SECOND TABLE. CAN SOMEBODY HELP IN WRITING THAT TRIGGER..? HOW CAN I DETERMINE WAETHER THE RECORD IS BEEN INSERTED OR UPDATED OR DELETED.
DO I HAVE TO WRITE A SEPERATE TRIGGER FOR EACH ACTIVITY..OR I CAN WRITE IT IN THE SINGLE TRIGGER..?
I have a parent table with 27 Columns and Child Table with 37 colums - when even there is an update in any of the columns on Parent or Child table, I require new record inserted into Audit_Parent and Audit_child table. Please help with SQL Code on Create Trigger and insert records into Audit_parent and Audit_child when an Update occurs on any of the columns. Insert into AuditParent and AuditChild should occur whenever there is an update on either Parent or child table.
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 have to create a trigger that will log who changed information on a table and when (NOT what they have changed).
My idea is to get the users name and see if it is in a table if not create it and get the associated ID, also get the ID of table that was accessed along with the ID of the type of task that was performed. Take this data and insert it into a table.
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
How would I write a trigger that updates the values of a Descriptioncolumn to upper case for even IDs and to lower case for odd IDs? Ineed this trigger to fire for INSERT and UPDATE events.
In recent testing, I have found that the trigger function UPDATE under SQL Server 6.5 SP5 behaves differently then SP4. For insert, the update function returns true on items that have not been explicitly inserted.
Is this a bug? Is this a new feature change? Where can I get more information on a bug list for SP5?
Hi, I'm taking an Excel spreadsheet (that could have around 30k rows) and processing it in SSIS. I essentially have a flag in one of the spreadsheet cols that indicates whether the record is already in the database or not.
I'm splitting the data using a conditional split on this column and using a OLE DB Destination (Fast Load) to perform the inserts and a OLE DB Command to fire a stored procedure to perform any updates. Both the OLE DB Destination and the stored procedure are hitting the same table and the two operations could be executing at the same time as they both appear directly after the Conditional Split, so the OLE DB Destination is set NOT to lock the table.
This seemed to work OK until recently. I've just added 2 triggers onto the table in question which I don't want to fire 30,000 times during the import. As the OLE DB Destination is set to use Fast Load, it doesn't fire the triggers - cool. In the update stored procedure it disables the trigger before performing it's update and re-enables the trigger when finished. Currently this does mean that if you only had updates, the trigger could be enables/disabled 30,000 times. That sounds kinda bad, but I don't really know if this carries a large overhead or not?
If, when importing now you have both updates and inserts the whole process locks up. From looking at activity monitor, it seems as though the INSERT gets suspended.
Do I have a fundamental problem with how I've structured the Data Flow or am I just being really stupid in Enabling/Disabling a trigger that many times, which is probably causing the problem?
I have created a job that fill and update a database from a source db with same structure.
INSERT code is made up comparing the pk column in the source and dest db, the missed ones are filled in the destination.
UPDATE: check col by col, if any change value exists, updated is performed with the following statement for any tables in the DB
UPDATE tableADest
SET col1=source.Col1, col2=source.col2, ... coln=source.coln
FROM tableASource source
INNER JOIN tableAdest dest
ON dest.colpk = source.colpk
The main problem is that I cannot identify the row update in the souce db, everytime I have to compare the whole equivalent tables (source and dest db), because there are not timestamp, updated cols or any cols usefuls, to have a subset of data and find any new or upadeted rows.
I tried replication, but it does not work on that db.
So I created a trigger for each table where new insert or updated row must be detected. The PKs are saved on tables.
The problem is that when I run the application it hold-on, when triggers are disabled the application run fine.
How can I use trigger on several tables without affectrunning application?
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 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'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?
I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:
--------------------------------- CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client] FOR INSERT, UPDATE AS declare @currency as char(50) declare @country as char(50)
declare cur cursor for SELECT currency, country FROMinserted
OPEN cur fetch cur into @currency, @country WHILE @@FETCH_STATUS = 0 BEGIN if not exists(select * from listinfoid where listname = 'currency' and listid = @currency) begin set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency') CLOSE cur DEALLOCATE cur RAISERROR (@currency,16,-1) with log return end if not exists(select * from listinfoid where listname = 'country' and listid = @country) begin set @country = (cast(@country as varchar (3)) + ' is not a valid contry') CLOSE cur DEALLOCATE cur RAISERROR (@country,16,-1) with log return end else fetch cur into @currency, @country
END CLOSE cur DEALLOCATE cur update Client set currency = UPPER(currency), country = UPPER(country) ---------------------------------
I use a cursor to handle multiple rows in an update query. (SQL2000-server)
Is there an easier och better way to do this? I´m a bit unsure of this code.
