I want to create a trigger that, when a field is updated or a record is inserted, counts the number of words in "field1", inserting this numeric value into another field in the same table. What would be the most efficient, fastest method for doing this?
View 15 RepliesI want to update a field and in this field insert a increment count, for example:
When I make, "Select * from Users order by User" displays:
User1 | NULL
User1 | NULL
User1 | NULL

User2 | NULL
and I want to do this:
User1 | 1
User1 | 2
User1 | 3
User2 | 1
User2 | 2
how to do this?

Hi,
I am trying to update a field in a temptable with the count of items in another table. To illustrate, CustomerID=23 and I want the number of occurences in the temp table. Here's the code which DOESN'T work:
INSERT INTO TempTable
(
CustomerID,
FirstName,
LastName,
DateAdded,
AlbumPicture,
LayoutCount
)
SELECT
Albums.CustomerID,
Customers.FirstName,
Customers.LastName,
DateAdded,
AlbumPicture,
COUNT(*) FROM Layouts WHERE Layout.customerID = Albums.CustomerID
FROM
Albums JOIN
Customers on (Albums.CustomerID=Customers.CustomerID)
Please take a look at the COUNT line. Here I want to count the occurences of a specific customerid in another table and put in into th LayoutCount field.
SQL server reports "Incorrect syntax near the keyword 'FROM'". Any ideas how to achieve this?
Many thanks!!

Hello again,
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.
Code Snippet
CREATE TABLE #Assignment
(CallID INT IDENTITY(1500,1) PRIMARY KEY,
AssignmentGroup VARCHAR(25),
Assignee VARCHAR(25)
)
GO
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Jim Smith')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Donald Duck')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Donald Duck')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Mickey Mouse')
GO
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?
Grateful for any advice, thanks

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL
FROM MYOTHERTABLE
I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

I've to write an trigger for the following action
When a entry is done in the table Adoscat79 having in the index field Statut_tiers the valeur 1 and a date in data_cloture for a customer xyz
all the entries in the same table where the no_tiers is the same as the one entered (many entriers) should have those both field updated
statut_tiers to 1
and date_cloture to the same date as entered
the same action has to be done when an update is done and the valeur is set to 1 for the statut_tiers and a date entered in the field date_clture

Hi -
I know my way around VS but I am just exploring "advanced" SQL Server 2005 and have run into a challenge which I think a trigger could solve, but I am not sure and also don't know how to set that up. So any help or links to tutorials are highly appreciated.
Here is the challenge: I have a table with a number of fields, among them RequestID (bigint) and Booktime (datetime). What I would like to happen is whenever someone writes a value different from NULL into RequestID, Booktime gets set to the current timestamp. When RequestID gets set to NULL, Booktime gets set to NULL.
Is there a way to do this with a trigger (or an otherwise elegant way)?
Thanks in advance for ANY help or ideas.

I'm tracking sales reps and the companies they represent. I have 2 tables. A header table that has the SalesRep (a key field) the name, phone, address, etc.A line file that will have the sales rep multiple times, each line having a vendor they represent.
SalesRepHeader table:
SalesRep name phone VendorList
Bob Bob_Smith 111-222-3333
John John_Young 123-456-56789
Mary Mary_Kerns 567-876-98765
[code]...
Whenever the SalesRepLine file is added to or updated I want the header file field VendorList to be updated with a concat of the vendors for this sales rep so the SalesRepHeader file would look like this.
SalesRep name phone VendorList
Bob Bob_Smith 111-222-3333 Samsung, Kenwood, JVC
John John_Young 123-456-56789 Apple, HP

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?

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.

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
[code]....
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.
Here is the SQL I have so far.
-- Primary Database Tables --
CREATE TABLE Physician (

Last_Name varchar(100),
Mobile_Number varchar(15),

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.

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.

View 1 Replies View RelatedHi,
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?
Thanks in advance.
Hello,
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?
Thank

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.
Can I do this with one trigger?
Thanks
