CREATE TABLE [dbo].[apcName](
[SysID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[RIN] [int] NOT NULL,
[Name] [varchar](80) NOT NULL,
[DimTab] [tinyint] NOT NULL,
[code]....
If I have an Insert trigger to set the RIN field to the next available number in the sequence of the RIN column, why does the following work for inserting 1 and only 1 record at a time but fails if doing multiple rows with a single insert?
Code:
-- Insert Trigger
UPDATE xRec
SET RIN = (Select MAX(RIN) + 1 from apcName)
FROM apcName xRec
JOIN inserted ins
ON ins.sysID = xRec.sysID
i want to write a database trigger to increment the salary by 10% for technicians who have done three tests on a particular date.
there are two employee types.(1)technicians (2)traffic controllers. employee category is defined in "Type" attribute of Employee table. the increment should happen only to technicians.thank you in advance.
hi,i am a beginner to ms sql server2000i have a tablecreate table ddd (a int, b int)by table structure is a bnow when i enter a value in b column suppose '2' in column bbext time when i insert a value in the column a i have to get the valuein b as 3 is thi spossible with triggersinsert into gdg values (1,2)a b1 2insert into gdg (a) values(2)a b2 3----------------> i have to get this 3 automaticallyis there any method to get thispls help mesatish
I Have a table that needs to have 2 unique number.
detail_id and detail_print_id.
detail_id is already an IDENTITY.
both fields need to be different, because when importing, it imports the same data into a table twice, with only a slight data change (and id is not one of the changes).
So I thought i could do the following:
detail_id INT NOT NULL IDENTITY(1,2), detail_print_id INT NOT NULL IDENTITY(2,2), --blah blah
that way, the detail_id will always be odd, and the detail_print_id will always be even. however SQL Server 2005 only allows 1 identity per table, and both these fields need to be auto generated when the field is inserted, so as to prevent double data.
is there anyway I can create a int column to auto increment, without the column being an IDENTITY??
also, I would prefer to not have to create a second table with a single column just for this work.
i have got 22,000 rows in a table, i want to update the records to have to start id of 70000 which increments to 70001, 70002 ? how would i go about doing this ?
Is there an easy and fast way to increment a value by 1 in a database? For example if a value is 106 I will need to make it 107. Is there a fast way to do this?
If there is one field such as Seq No in a table and if we entered some data .. and if we update one record of Seq No then the below records of Seq No should be incremented in that table
for example there are 10 seq no's and if i had updated the seq no 4 to 5 then the 5 shuld b inc 6 and 6 to 7 etc............
at preasent i wrote only update in sp of that particular record: like this
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go
ALTER PROCEDURE [dbo].[UpdateSelected] (
@Description NVARCHAR(30), @SequenceNo int ) AS
UPDATE Sequence SET Description = @Description, SequenceNo = @SequenceNo
WHERE SectionID = @SectionID but now i need additional functionaly like inc the remaining sq no above that given no...

I have a table with an automatic count int. What I want to know is there an sql statement to return the next increment from the sequence. Any help would be appreciated.
This is my first SSIS query. I have just started with ssis and have the following task
I am looping text files in a folder using foreach. I transfer text file data to sql server. I want to count the total rows are that transferred in all the text files after the foreach loop finishes. I user RowCount but it gives count of only current textfile. It gets reset each time the loop iterates. I want something like @count = @count + currentnoofrows in current text file.
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.
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm.... This example seems to be workingfine so it must be something with my specific schema/code.

This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.
The following code write audit entries to a Table called 'Audit' with columns 'ActionType' //varchar 'TableName' //varchar 'PK' //varchar 'FieldName' //varchar 'OldValue' //varchar 'NewValue' //varchar 'ChangeDateTime' //datetime 'ChangeBy' //varchar

The trick was getting the Table Name and the Primary Key Columns. I hope this code is found useful.
I'm using SQL Server 2000 with MS Management Studio. I have a table that has 400 rows. I have setup the Primary key to increment automatically. How do I setup so that the next record starts at 4001 and up? Right now it starts at 1274, for example. So besides dropping the table and re-creating it, how do reset it so it counts from sequentially from the last row inserted?
How can you increment row by row through a table using a stored procedure? I am trying this but getting error on SET statement - Line 6: Incorrect syntax near '.'. PROCEDURE asuodem.spA_LinkSpinner ASWHILE (tblLinkInfo_OLD2.L_ID IS NOT NULL)BEGINIF (tblLinkInfo_OLD2.L_Rank > 10) AND (tblLinkInfo_OLD2.L_Rank < 300)SET tblLinkInfo_OLD2.L_Rank = Convert(int, (250-25+1)*RAND())ELSE CONTINUEENDRETURN
It's been a long time since I've had to check an index for the highest value, then add 1, to create a new unique key. These past few years, it seems this is usually done for you. But now that I'm working with MS-SQL, I don't see it. Is it there? It's doesn't seem to be inherent in the definition.
Hello, Firstly Hello to everyone I'm new the forum and fairly new to .net I'm working on web datbase application using visual studios 05 and MS SQL05 I've used 2003 (briefly) before but 2005 is very new to me. To my problem I download the GUI interface from microsoft so I can now setup a local database and do my own testing. I have created the table and fields with in it however on a particular table i have made a primary Key and left it as an INT but I would like to set it as auto increment ! I dont know how to select that option as i was used to mysql way of doing things or does this have to be done as a stored procedure ? Any assistance much appreciated.
I am very new to using SQL server 7. I've always used mysql in the past. I cant figure out howto create a autoincrementing key for my tables... is it possible to do in SQL7?? If so.. how.. i thought you just set the datatype to auto increment etc...
I is true that SQL-Server use lower values than last integer value (in auto incremet field). Is there option that i could prevent that. So the Server would always put + 1 for the auto increment value.
I would like to avoid using a cursor. I am updating several rows in a table with sequential numbers starting at a number I pass into the Stored Procedure. Is there a way to do this with one update statement?
Users for a long time have been able to post new topics in our forums. However, a short time ago, the some users began to experience problems. What I have narrowed it down to is that upon inserting into the table, sometimes id value for the topic is the same as an id that is already in the table, so it fails to insert the record (due to a constraint). However, the topic id column is an auto-increment column and should just assign the next number for the id value.
If delete all the records from a table that has an incremental identity. Is there a TSQL way of reset the first number on an insert back to be 1 again without going to the table taking it off then saving it the putting it back on again?
I have important a table from mircosoft access into ms sql server 2000, I've created a new ID row and set the primary key - but I need to use the ID from microsoft access as well. therefore I'd like to add an auto increment +1 on the old access ID field... but how do I do that?

Hi. Am creating a database in SQL and one of the field of my table is customer_id. I want this customer_id to be auto generated and auto increment. I was reading about Identity but it was too complicated to grasp. So how can that be done in a very simple way. Thanks
