I have a 3rd party program that creates some tables in my sql server
2005 database, then it does inserts on the tables. Is there a way I
could create a system level trigger that would immediately and
automatically modfiy the table structure after the table is created
(hopefully before the inserts occur)? I need to change a field from
numeric(5, 0) to numeric(15, 0).
Thanks,

I have converted Access database to sql express. Access Database had AutoNumber FIelds for which trigger was generated by Upsizing wizard.
Now when I import data from client the autonumber field value changes because trigger is fired which distroys all links
I want to modify trigger so that it generates new number only when it is not supplied in a insert command.
Please help. Code is given below. Also suggest how to save because when I use save, it asks for a new .sql file name and a new file is generated instead of modifying the same trigger
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[T_AcControlLimit_ITrig] ON [dbo].[AcControlLimit] FOR INSERT AS
SET NOCOUNT ON
DECLARE @randc int, @newc int /* FOR AUTONUMBER-EMULATION CODE */
/* * RANDOM AUTONUMBER EMULATION CODE FOR FIELD 'IntAcControlCode' */
SELECT @randc = (SELECT convert(int, rand() * power(2, 30)))
SELECT @newc = (SELECT IntAcControlCode FROM inserted)
UPDATE AcControlLimit SET IntAcControlCode = @randc WHERE IntAcControlCode = @newc
Within a trigger, is it possible to modify a row before it is inserted in SQL Server 7? I need to update two columns before the row is inserted by the trigger.
View 1 Replies View RelatedI am absolutely stumped here. I have the SQL server management studio loaded up, the trigger in question highlighted. I right click and select "Modify". I see the trigger code in a window, i make my modifications, and hit ctrl-f5. It compiles without any errors. Now I hit CTRL-F4, and it asks me to save to a file. (Now the original trigger was not saved 'as a text file' - that I can find anywheres on my hard drive. I save it anyways, and the editing window is gone.) I right click on the trigger and select "modify" and the code is back to the way it was. I just spent the last two hours trying to modify this - surely there is a way to modify a trigger?

Hi,I'm a newbie to sql server and this may be a really dumb question forsome you. I'm trying to find some examples of sql server triggers thatwill set columns (e.g. the created and modified date columns) if the rowis being inserted and set a column (e.g. just the modified date column)if the row is being updated.I know how to do this in oracle plsql. I would define it as a beforeinsert or update trigger and reference old and new instances of therecord. Does sql server have an equivalent? Is there a better way to dothis in sql server?Thanksericthis is what i do in oracle that i'm trying to do in sqlserver...CREATE OR REPLACE TRIGGER tr_temp_biubefore insert or updateon tempreferencing old as old new as newfor each rowbeginif inserting then:new.created_date := sysdate;end if;:new.modified_date := sysdate;end tr_temp_biu;

Hi,
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
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname

I've a table with an ID column, it is an auto increment id column that increases by 1.
ID
--
9724
9725
When my webhost restarts SQL, or some other random act of God, this ID jumps by 1000. Today it leapt from 9725 to 10725, which just doesn't work for me. It results in my having to upload the last known good copy of the database.
My host says they can't change the 1000 row buffer, MS apparently doesn't deem this an issue, and I'm quite frustrated. I used to be able to modify certain settings in SQL since I was using an SQL 2008 database under SQL Management Console but since my host upgraded to 2012, and I'm running XP, there is no forward compatibility and many options are no longer possible (eg. modifying a column, now it has to be done via clicking query and entering a SQL command rather than just right clicking on the column)
So long story made short... is there a way to modify my table (named "places") to turn OFF the autoincrement Id and perform a simple means to figure out the next possible value?
example:
id, place, locstion, gps, v2, v3, v4, comment
================================================
9720, Bill's House, Toronto, 43.4453, y, n, c, This was a good place to eat
9721, Dime a Dozen, Cambridge, 42.4453, n, e, d, A good place to take photos
I'd have to pull the highest value of ID (+1 to it) and then do a standard INSERT into places (id, place, location, gps, v2, v3, v4, comment) values (9722, etc...)I guess my concern is if the autoidentity is turned off, will SQL allow a new value to be entered via INSERT? I'm also using the @@identity to find the last known ID when I want to direct the user to the entry that they've just created and I don't know what that # is just yet. Would the @@identity still work?
Hi all I was wondering how to do an ALTER command on a Table but without specifying Column Names but rather attempting to overwrite the Table itself with the new fields specified? For instance if I have Table_1 consisting of the following fields:
IDFirstNameSurname
Then use the following ALTER command:
Code Snippet
ALTER Table Table_1
(
ID Int,
FirstName VarChar(50)
)
This would then drop Surname from the Table and leave only ID and FirstName inside it. Is this possible? I have been searching google but can't seem to find what I am looking for.
Thank for comments + suggestions. Regards, Onam.
Dear all
I have a problem about replication, so I want to modify some columns in a table, but my database using replicate. How to do it?
Please solution.
Thank.
PC Kaveesin.
Our ERP vendor is helping us migrate from one version of their product to another. In the new version, they have added some columns and changed a few data types in several existing tables.
They sent us a list of the modifications that were necessary, which we did (painstakingly) by hand. But, for other reasons the update failed and we have to start anew.
This got me thinking: is there any way to do this kind of update via a script/stored procedure? I don't have their exact changes handy, but it was stuff like the table "inmast" needs a column of varchar(50) called "lotc" added to it, and the "intime" table needs the datatype of columns "Mon" "Tue" "Wed" changed from text to varchar(50), stuff like that.
Is it possible to do stuff like that in a SP?
I am quite new to MS SQL, and I want to read rows from a todo table, andwhen a row has been processed, I want to delete that row.Ages ago in MySQL I would probably have locked the table, select, processa row, delete a row, unlock the table.I have been reading through the documentation from MS SQL, but it's notclear what exactly I should do.Since I want to lock only one table in the select (the others just providedata, and are not modified), what's a good solution?--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html
View 2 Replies View RelatedIn Enterprise Manager, I would right click on the table, choose Open Table and Query where I could select specific records and (most importantly) could alter data in a record by deleting the text, adding or over-typing.
In 2005 Server Management Studio I just cannot figure how to do this. I'm guessing that I need the 'Script Table as' option but then what?
I have managed to open selected data using the New Query and then Design Query in Editor, but the results only appear in a kind of view form and I cannot seem to alter any of the data entries, I get dotted lines around the selected field.
Please help, it seemed so much easier in 2000!
What's the answer for this and how ? If it is yes then How ?
View 4 Replies View RelatedHey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

I want to insert a row for a Global user in Table 'A' whenever ADO.Net code inserts a Local user row into same table. I recommended using a trigger to implement this functionality, but the DBA was against it, saying that stored proecedures should be used, since triggers are unreliable and slow down the system by placing unecessary locks on the table. Is this true OR the DBA is saying something wrong? My thinking is that Microsoft will never include triggers if they are unreliable and the DBA is just wanting to offload the extra DBA task of triggers to the programmer so that a stored procedure is getting called, so he has less headache on his hands.Thanks
