T-SQL (SS2K8) :: After Update Trigger - Only Insert Records Not Exists
Jul 30, 2014
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 ;
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 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.
Ok, I'm looking to get counts on historical data where the number of records exists between two dates with different years. The trick is the that the dates fall in different years. Ex: Give me the number of records that are dated between 0ct 1, 2013 and July 1, 2014.
A previous post of mine was similar where I needed to get records after a specific date. The solution provided for that one was the following. This let me get any records that occured after May 1 per given Fiscal year.
SELECT MAX(CASE WHEN DateFY = 2010 THEN Yr_Count ELSE 0 END) AS [FY10], MAX(CASE WHEN DateFY = 2010 THEN May_Count ELSE 0 END) AS [May+10], MAX(CASE WHEN DateFY = 2011 THEN Yr_Count ELSE 0 END) AS [FY11], MAX(CASE WHEN DateFY = 2011 THEN May_Count ELSE 0 END) AS [May+11], MAX(CASE WHEN DateFY = 2012 THEN Yr_Count ELSE 0 END) AS [FY12],
[Code] ....
I basically need to have CASE WHEN MONTH(OccuranceDate) between Oct 1 (beginning year) and July 1 (ending year).
it's me again :) I've got a - what I think - simple question. There is table A with Col1,Col2,Col3 and Table B with Col1,Col2,Col3
I want all rows from B in A. If a row already exist in A, then update all columns, else just insert the row. Can someone please help me with a small syntax. Thank you!
I have a 'Products' table (with: 'uid' and 'CatName' columns) and 'ProductCategory' table (with: 'uid', 'ProductID', 'CategoryID' columns).
I got stored procedure below to update or insert new row to 'ProductCategory' table whenever 'Products' table has been updated or new products has been added to it.
Update part works just fine but when new row has been added to 'Products' this storedProc dosn't insert it into 'ProductCategory' table, it does that only when 'ProductCategory' table is empty, I'm afraid it's because first column 'uid' in 'ProductCategory' table is an Identity column... I’m not sure how should I go about that problem. This is my stored procedure:
DECLARE @CatNo INT, @CatName varchar(10) SET @CatNo = 2 SET @CatName = 'bracket'
IF exists (SELECT ProductID from ProductCategory, Products where ProductCategory.ProductID = Products.uid and Products.CatName = @CatName ) BEGIN UPDATE ProductCategory SET CategoryID = @CatNo FROM Products WHERE Products.CatName = @CatName and ProductCategory.ProductID = Products.uid END ELSE BEGIN INSERT INTO ProductCategory ( ProductID, CategoryID) SELECT uid, @CatNo FROM Products WHERE Products.CatName = @CatName END
SET @CatNo = 3 SET @CatName = 'cable'
IF exists (SELECT ProductID from ProductCategory, Products where ProductCategory.ProductID = Products.uid and Products.CatName = @CatName ) BEGIN UPDATE ProductCategory SET CategoryID = @CatNo FROM Products WHERE Products.CatName = @CatName and ProductCategory.ProductID = Products.uid END ELSE BEGIN INSERT INTO ProductCategory ( ProductID, CategoryID) SELECT uid, @CatNo FROM Products WHERE Products.CatName = @CatName END (... Goes for another 37 categories)
In MS Access I can do in one SQL statement a update if exists else ainsert.Assuming my source staging table is called - SOURCE and my targettable is called - DEST and both of them have the same structure asfollowsKeycolumns==========MaterialCustomerYearNonKeyColumns=============SalesIn Access I can do a update if the record exists else do a insert inone update SQL statement as follows:UPDATE DEST SET DEST.SALES = SOURCE.SALESfrom DEST RIGHT OUTER JOIN SOURCEON (DEST.MATERIAL = SOURCE.MATERIAL ANDDEST.CUSTOMER = SOURCE.CUSTOMER ANDDEST.YEAR = SOURCE.YEAR)This query will add a record in SOURCE into DEST if that record doesnot exist in DEST else it does a update. This query however does notwork on SQL 2000Am I missing something please share your views how I can do this inSQL 2000.ThanksKaren
I had implemented as in the link to insert or update http://blogs.conchango.com/jamiethomson/archive/2006/09/12/SSIS_3A00_-Checking-if-a-row-exists-and-if-it-does_2C00_-has-it-changed.aspx
What i want to know is... how can i assume there are no duplicate records. I used Distinct keyword and queried it showed me all are distint but some where i find some duplicates just don't know why i am having when i look at the data both are exactly same...
I've decided to post this as a sticky given the frequency this question is asked.
For those of you wishing to build a package that determines if a source row exists in the destination and if so update it else insert it, this link is for you.
If you want to do a similar concept to Jamie's blog post above, but with the Konesan's Checksum Transformation to quickly compare MANY fields, you can visit here: http://www.ssistalk.com/2007/03/09/ssis-using-a-checksum-to-determine-if-a-row-has-changed/
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.
I have a pretty complex query that returns three records. For simplicity sake, the results can be simulated with this query:
Select 5 AS InternalAuditTeamEmployeeID, 1 as InternalAuditTeamID UNION ALL Select 11, 2 UNION ALL Select 14, 3;
I want to take this result and update the Flag field to true in my table tblInternalAuditTeamEmployee (CREATE statement below) for any InternalAuditTeamEmployeeID that is less than or equal to the ones in the results above, but by group. My results would look something like this using the data below and the results above.
I was thinking I could somehow use ROW_NUMBER(PARTITION BY InternalAuditTeamID ORDER BY InternalAuditTeamEmployeeID DESC), but not sure how to get the results of "WHERE <= InternalAuditTeamEmployeeID For each particular group".
CREATE TABLE STATEMENT:
CREATE TABLE [tblInternalAuditTeamEmployee]( [InternalAuditTeamEmployeeID] [int] IDENTITY(1,1) NOT NULL, [InternalAuditTeamID] [int] NOT NULL, [EmployeeID] [int] NOT NULL,
we have various user defined fields, so when the user insert new value to this field , i want new records (other user field to get populated) be inserted relevant to the inserted value FROM another table (lookup)
This field is a drop down list , after insert committed , i want other user defined field to populate.
Scenario. Drop down is a list of users, after selecting and updating then i want contact details of the above selected user be populated.
CREATE TRIGGER User_Defined_field_KAE ON [dbo].[AMGR_User_Fields_Tbl] AFTER INSERT
AS
INSERT INTO [dbo].[AMGR_User_Fields_Tbl] (Client_Id, Type_Id, name SELECT Client_Id, '1089', A.USER_PHONE_1 FROM inserted , [dbo].[ADMN_User_Details] as A WHERE name = a.user_id;
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!
CREATE TRIGGER ActiveCard

FOR Insert (when i insert a new row in Access Control)
AS UPDATE UniqueCard
( to update the matching (match IDNum) row within UniqueCard table)
Set UniqueCard.Active = Inserted.Active (card and active are of the same type)
I have a After insert, update trigger. When I update multiple records with unique constraints column in it update fails. But if this a single record update it works.
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.
I am developing an application in vb.net 2005 using SQL Server 2000. In this I have two tables SessionMaster and SessionChild. Fields of session master - SessionMastId, Start_Date, End_Date, Session_Type, Fields of session child - SessionChildId, SessionMastId, UserName, Comment. SessionMastId and SessionChildId are primary keys of respective tables and also they are auto increment fields. Please how to write trigger to insert record into both tables at a time.
Good day to all, I am new here so i hope i am doing things correctly.
The Company i work for make coils of shaped wire and work a 6 - 6 shift pattern
I have a database that is updated from a data collection source (MS Access) at 06:00 every morning. This seems to be working ok, my problem is that most coils fit nicely into the 6 - 6 shift pattern, but some now and again drift over into the next shift. I have written a crystal report that picks up this data. at the moment the coils are put in the database as: [Coil Start Time], [Coil Finish Time], [Coil Start Weight], [Coil Finish Weight], etc.
I have written (been helped to write) a SQL statement that will do the following:
Step 1: If the Coil Finish time is greater than the shift end time, then set the shit end time to be coil end time and zero start and finish wheight. Step 2: The original Coil record is duplicated and Coil Start time set to start time of shift, all other data left alone.
Example of code:
-->>
SELECT [Batch Name], [Batch Start], [Batch End], [Coil Start Weight], [Coil Finish Weight], [Product], [Shift], [Operator ID], [Works Order No] FROM dbo.tblCoilData WHERE (DATEPART(hour, [Batch Start]) >= 6 AND DATEPART(hour, [Batch End]) < 18) OR ((DATEPART(hour, [Batch Start]) < 6 OR DATEPART(hour, [Batch Start]) >= 18) AND (DATEPART(hour, [Batch End]) < 6 OR DATEPART(hour, [Batch End]) >= 18)) UNION ALL SELECT [Batch Name], [Batch Start], DATEADD(hour, 17, DATEADD(minute, 59, CONVERT(char(10), [Batch End], 101))), 0, 0, [Product], [Shift], [Operator ID], [Works Order No] FROM dbo.tblCoilData WHERE DATEPART(hour, [Batch Start]) >= 6 AND DATEPART(hour, [Batch Start]) < 18 AND (DATEPART(hour, [Batch End]) < 6 OR DATEPART(hour, [Batch End]) >= 18) UNION ALL SELECT [Batch Name], DATEADD(hour, 18, CONVERT(char(10), [Batch Start], 101)), [Batch End], [Coil Start Weight], [Coil Finish Weight], [Product], [Shift], [Operator ID], [Works Order No] FROM dbo.tblCoilData WHERE DATEPART(hour, [Batch Start]) >= 6 AND DATEPART(hour, [Batch Start]) < 18 AND (DATEPART(hour, [Batch End]) < 6 OR DATEPART(hour, [Batch End]) >= 18) UNION ALL SELECT [Batch Name], [Batch Start], DATEADD(hour, 5, DATEADD(minute, 59, CONVERT(char(10), [Batch End], 101))), 0, 0, [Product], [Shift], [Operator ID], [Works Order No] FROM dbo.tblCoilData WHERE (DATEPART(hour, [Batch Start]) < 6 OR DATEPART(hour, [Batch Start]) >= 18) AND DATEPART(hour, [Batch End]) >= 6 AND DATEPART(hour, [Batch End]) < 18 UNION ALL SELECT [Batch Name], DATEADD(hour, 6, CONVERT(char(10), [Batch Start], 101)), [Batch End], [Coil Start Weight], [Coil Finish Weight], [Product], [Shift], [Operator ID], [Works Order No] FROM dbo.tblCoilData WHERE (DATEPART(hour, [Batch Start]) < 6 OR DATEPART(hour, [Batch Start]) >= 18) AND DATEPART(hour, [Batch End]) >= 6 AND DATEPART(hour, [Batch End]) < 18
<<--
I have 2 options now
option 1: Leave this as a SQL View and report from this
option 2: Insert updated records to the tblCoilData table so that the data in the table is permanent
I would prefer option 2 but am a bit of a nugget when it comes to writing update / insert statements, Could someone please help me with this
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?
