SQL Server 2000 : I have a series of tables which all have the same
structure. When any of these tables are modified I need to syncrhonise
all of those modifications with one other table wich is a sort of merge
of the individual tables with one extra column.
For most of these tables this is not a problem. The problem arrives
when one of the tables has an ntext column which obviously can not be
used in an update or insert trigger.
Here's an example of one of them:
CREATE TABLE tblImages(
ID INT IDENTITY(1,1) PRIMARY KEY,
Inventory nvarchar(8) NOT NULL,
Coll nvarchar(8) NOT NULL,
ImageFile nvarchar(128) NOT NULL,
ImageNotes ntext NULL,
TS timestamp NULL
CONSTRAINT U_Images UNIQUE NONCLUSTERED (ItemCode, Inventory, Coll,
ImageFile)
I then had created an update trigger which looked like this:
CREATE TRIGGER COLLNAME_UTRIGGER ON COLLNAME_Images
FOR UPDATE
AS
BEGIN
UPDATE tblImages SET
Inventory = inserted.Inventory,
Coll = 'COLLNAME',
ImageFile = inserted.ImageFileName,
FROM inserted INNER JOIN tblImages ON inserted.ItemCode =
tblImages.ItemCode AND
inserted.Invventory = tblImages.Invventory AND tblImages.Coll =
'COLLNAME' AND
inserted.ImageFileName = tblImages.ImageFile
UPDATE tblImages
SET ImageNotes=inserted.Notes
FROM inserted INNER JOIN tblImages ON inserted.ItemCode =
tblImages.ItemCode AND
inserted.Inventory= tblImages.Inventory AND tblImages.Coll =
'COLLNAME' AND
inserted.ImageFileName = tblImages.ImageFile
END " & vbCrLf)
The first update in my trigger, be it an update or insert trigger,
works fine. It crashes with the "Cannot use text, ntext or image
columns in the 'inserted' or 'deleted' tables." error in the second
part.
I have read various messages through the Internet on this and several
of them reference using INSTEAD OF triggers and views. I have never
used those before as this is my first work with SQL 2000. None of the
examples of INSTEAD OF triggers I have seen yet use the actual inserted
tables and I haven't quite understood how to use them correctly.
Can someone help me with the basic syntax as this trigger is one of
several that I am going to have to get working.
Thank you in advance for any help, assistance, suggestions or
"direction pointing" you may provide.
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 recently moved a database from a SQL server 2005 box to new server running SQL server 2012. The update/insert triggers that were working on the tables to handle referential integrity checking are no longer working. Running the same database on SQL Server 2008 and everything works.
Here is one of the trigger that throws the error 44446
USE [M2Data] GO /****** Object: Trigger [dbo].[tblContacts_UTrig] Script Date: 3/11/2014 9:07:13 AM ******/ SET ANSI_NULLS ON
[code]....
I have verified that there is a matching key in tblCompanys. Also, when I run a query to update tblContacts the error message appears but the update does take. If I try and edit the row directly by selecting edit top 200 rows - the error message appears and the update does NOT take.
These triggers were probably added to the database during an upsize from MS Access to SQL Server 7 way back. What am I missing - is it something in the syntax?
I want to be able to duplicate every single record that is inserted or updated in a particular table to another table, but not the delete. Is the best way to set-up a trigger? If so can anyone provide me with an example of how to do this? Also could you just duplicate certain columns in the row I would you have to do all columns?
Hello, I am creating triggers on th efly from stored procedure.I have table 1in db1 and table2 in db2 and i want to capture inserts ,updates and deletes in table 1 to table 2 for which triggers are getting created from SP in SQL 2000.
If i create instead of triggers then its working fine but the row will not be inserted in the main table and i need rows to be inserted in the main table.The tables is having ntext columns.Any work around for this?
A sql server 2000 table contains a ntext field that needs to be updated. The update is replacing a particular string in the ntext field. I heard it's hard to do it in sql server 2000 itself. Can it be done easily in an SSIS? Please kindly provide example. Thanks.
i define a clumn like this: clumn name: Body data type: ntext then i run a store procedure which is defined as : create insert_artcle as ( @body ntext ) insert into article{body} values{@body} but the data get into the database is truncated to 8 charactors what is the problem? Is it has something to do with the ntext size 16?
I need to find a way to update a notes field that is ntext in a table with an update statement. The code will run as a SQL job. I though something like the following, but doesn't like it: update dbo.myTable set notes = notes + ' addtional notes to append' Any ideas? thanks...
Loading thousands of records to the DB through bulk insert. There's one field NText which I have left NULL because it will be hard to gen dummy flat file to it.
I have another table which has the Ntext Value which i will want to copy and duplicate to the other table.
what is the way to do it?
simply said i want to update a record with NULL value from one table with NText field with the value from another table..

I've got a table that I have to update in preparation for our environment move (2k to 2005 SP2). The developers that designed the application created a table called schemas, which holds the contents of an XML file inside of an ntext field named Data.I need to parse through the field and do a find/replace to replace all instances of www.site.com with www7.site.com. It's all over the place in the file. The problem is, that the datalength() of each of the fields (there are 2 rows) are above 15000.normally, I'd run something like this:update schemas set data=replace (cast(Data as varchar(max)),'www.site.com','www7.site.com') where data like '%www.site.com%'Smaller columns it works great - but it won't work on these because they're too big (the update will chop anything beyond the varchar(max) value). I could do it manually, but this DB will be refreshed from production on a weekly basis and I'd like to script as many of the environment changes to the DB as much as possible. Any ideas?
Hi, I've been reading all sorts of info on the ntext field. I needthis to store xml documents in sql server via a stored proc.Because of its size, I apparently can not use SET (as in UPDATE)therefore I'm trying to do an INSERT of the row with this field (afterdeleting the old row).CREATE PROCEDURE dbo.UpdateXmlWF(@varWO varchar(50)@strWF ntext@varCust varchar(50)@varAssy varchar(50))ASINSERT INTO tblWorkOrders (WorkOrder, Customer, Assy, xmlWF) VALUES(@varWO, @varCust, @varAssy, @strWF)I'm using MSDE so I can't tell what's wrong...it just won't save theproc.PLEASE HELP!Thanks, Kathy
Hi, I've read conflicting articles on updating an ntext field in acolumn.My ntext field will exceed 8,000 characters (typically twice that size-- but just a text string).One article (I think from MicroSoft) said you could NOT use ntext inan UPDATE statement, but I've seen examples from other people usingit...but don't know if it's related to the size/characters issue.Is this true or not?Thanks very much...Kathy
Hello, what i want is simple. This is a simple forum, it has several topics (that the users can create), when a user create a topic, its stored in forum_topics. The user can then view the topic and post a response that is store in forum_answer, the user can also add this to his favorite list, forum_favorites is simple, contains a TopicID that refers to the topic, a username of the user that has the topic on his favorite list and a auto increment id to be able to delete specified topic favorites. Now my question is: when a user posts a answer to Topic X, i want a predefined message to be sent to post_inbox for all the users that has Topic X in their favorite list. How can i get MS SQL 2005 to get all the users from Topic X and then loop thru them and insert a new post into post_inbox?
I've been reading the docs and playing around, but I'm still notgetting the difference.

I am running this query to an sql server 2000 database from my aspcode:"select * from MyTable whereMySqlServerRemoveStressFunction(MyNtextColumn) = '" &MyAdoRemoveStressFunction(MyString) & "'"The problem is that the replace function doesn't work with the ntextdatatype (so as to replace the stresses with an empty string). I hadto implement the MySqlServerRemoveStressFunction, i.e. a function thattakes a column name as a parameter and returns the text contained inthis column having replaced some letters of the text (the letters withstress). Unfortunately, I could not do that because user-definedfunctions cannot return a value of ntext.So I have the following idea:"select * from MyTable whereCheckIfTheyAreEqualIngoringTheStesses(MyNtextColum n, '" & MyString &"')"How can I implement the CheckIfTheyAreEqualIngoringTheStessesfunction? (I don't know how to combine these functions to do what Iwant: TEXTPTR, UPDATETEXT, WRITETEXT, READTEXT)
I am trying to understand how to use instead of trigger using an update.
Here are a few things that I need clarified.
- When using an 'instead of Update' trigger is this replacing any other Update that is happening to the Table.
- Or, is the occurence of the trigger happening after the update?
- Also, I have seen some syntax where people use: Update table set field1 = inserted.field1 from deleted, inserted, table where deleted.field1 = ....
Does this mean that when using the 'instead of' option it keeps track of what is being deleted and what is being inserted by using such things as deleted.field1 or inserted.field1?
What I need to do is check that the previous value in a particular field is null before updating it. I don't want to update a particular field that already contains a value in it.
Hi there I' d like to make a trigger which will come with some kind of message ( maybe jscript?) or printout, each time I insert new client into the Client table. Clent table has ClientID, ClientName, Address, EMail, and ContactPerson. Please help
I have written an Insert Trigger to examine newly inserted records and set some values. However, each time a record is inserted, all records are checked. How can I make the trigger work only on newly inserted records?
What would be the best way to handle different updates for a table, multiple triggers, or just one large triggger? I am not worried about their order of firing, just that they fire
I try to use trigger to see if Component table update at same time update the AssemblySubcomponent AssemblyID
but it say
Msg 4104, Level 16, State 1, Procedure trigupdateSubcomponentID, Line 6 The multi-part identifier "a.SubcomponentID" could not be bound.
the code look like
create trigger trigupdateAssemblyID on Component for update, insert as begin if update (ComponentID) update AssemblySubcomponent set a.AssemblyID= i.ComponentD from inserted i join AssemblySubcomponent a on a.AssemblyID =i.ComponentID
I have a situation where I need to create an insert trigger on table a which will create a corresponding record in table b. However before I insert the record i must obtain the max value for the record in table b and increment it by one. I have all this working. My question is if I just put a begin and commit with this statement is there a chance that when 2 users insert at the same time the max value may be incorrect say for instance
CREATE TRIGGER tr_cms_prov_ins ON provider FOR INSERT as declare @ndentPrid char(3), @nxtgenPrid char(7), @fname varchar(40), @lname varchar(40) begin tran select @ndentPrid = max(provider_id) from providerdnt if @ndentPrid is null set @ndentPrid = 1 else set @ndentPrid = @ndentPrid + 1
insert into dental..provider (provider_id, first_name, last_name, collections_go_to) select @ndentPrid, first_name, last_name','YYYYYYYYYYYYYYYNNNNN' from inserted commit tran
Will this do it or do I need to enforce some type of locking to handle the max value. There are no inserts into table b directly only by the trigger insert on table a
Hello all, I'm in the process of debugging a trigger i've written (which hasn't been any fun) and i have a question.
records for the table with the trigger are only inserted from a SP using an INSERT INTO ... SELECT statement. Multiple rows at a time.
question is.. does the trigger fire once for that insert into ... select or does it fire for each new row inserted by that statement. I was under the impression that it fires for each row but i'm not sure now because the table the trigger inserts to only has one row after the SP is run.
I created a trigger which looks like Create TRIGGER UpdateGenTables3 ON AWSWQ_Quizzes After insert as Begin SET NOCOUNT ON declare @TableName varchar(20),@Title varchar(20),@code varchar(20),@Gcode varchar(20),@uppercode varchar(20), @Description varchar(50) DECLARE DemoCursor CURSOR FOR Select QuizID,QuizTitle from AWSWQ_Quizzes group by QuizID,QuizTitle OPEN DemoCursor FETCH Next From DemoCursor INTO @code,@Title WHILE @@FETCH_STATUS = 0 BEGIN
INSERT INTO gen_tables (TABLE_NAME, CODE, SUBSTITUTE,UPPER_CODE,DESCRIPTION,OBSOLETE_DESCRIPTION) VALUES ('PRE_REQ_TESTS', @code, '', @code, @title, '') FETCH Next From DemoCursor INTO @code,@Title END CLOSE DemoCursor DEALLOCATE DemoCursor
end
The problem with my trigger is .I am not able to insert into my table AWSWQ_Quizzes the error i get when i try to insert is
Violation of PRIMARY KEY constraint 'pkGen_TablesTABLE_NAME'. Cannot insert duplicate key in object 'Gen_Tables'. The statement has been terminated. ---> System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'pkGen_TablesTABLE_NAME'. Cannot insert duplicate key in object 'Gen_Tables'.
I have been trying to implement a trigger that is fired when a record is inserted in a table, provided that certain fields in the inserted record meet specific criteria (what you'd find in a where clause). All examples I have come across so far involve cases where the trigger is fired off everytime there is an insert regardless of what values are being inserted.
Basically, Assume a table "Address" with colums House Number, Street Name, City, State, Zip Code. How do I make my trigger fire ONLY when a record with City = 'Boston' is inserted??
If I have a trigger on a field in a table, and I update one record trigger fire properly. If I do a update to that same field on all records in the table the trigger does not fire. I the error in the trigger, or do I need to change my update statement?
I would like to update foreign keys using triggers. At least thats what I think is the solution when having multiple references to a table in order to avoid the "cycles or multiple cascade paths" error message.
Anyway, here are three tables Dentist table dentist_id int identity (auto increment)
Patient table: patient_id int identity (auto increment)
Appointment: apointment_id int identity (auto increment) id_dentist int FK to dentist_id id_patient int FK to patient_id
I am gooling but cant find a way to make a trigger run only when the dentist_id from dentist table is updated. Also, is there a way to get the new id and old id somehow? I saw some posts with new.dentist_id and old.dentist_id but apparently is not for sql server.
Hi i have a view that contain multiple tables from my database and i want to view it on datagridview and update it's data some people says you can update joined tables using instead of triggers how is that ?is there any example ?
How do I set up an insert trigger to copy all of the inserted data to another table? In other words, when someone adds a new paramater in the params table, I want to automatically create a matching set of data in the goals table. Thanks,Krista
Hi There are 2 databases db1 and db2 on SQL server 7 with tables 1 and 2 respectively. Both these tables have a field called Quantity. IF quantity gets updated in table 1 then that change should be immediately reflected in table2. I though an update on table1 would serve the purpose but this trigger doesn't seem to be working however there are no errors during the syntax check. The code for the trigger that i have used on table 1 is as below CREATE TRIGGER [Qty_UPDATE] ON [Table1] FOR UPDATE AS IF UPDATE (Qty) BEGIN UPDATE db2.dbo.table2 SET db2.dbo.table2.qty = qty END Please help Thanks in advance
