Dec 28, 2007
i would to make a column contains of 3 characters and 6 auto increment numbers (example: "DLL - 123456")
and made it primary key and which data type i should use. i do not know whether i use after insert trigger in two columns one for three characters and another for code which has identity property >>>so please help me
Hi,Please can you let me know the best solution for creating a primary key which automatically increments by 1 each time a record is added. My current Primary key is of type "Int" which increments by 1 each time, but I would like my primary key to contain "ABC" before the 1. So each time a record is added I would like to see:-ABC000001 ABC000002ABC000003Etc, EtcI am using SQL Server 2000 and creating an ASP.Net application, will I need to write code in a Stored Procedure to do this?Regards,Brett
How do I make a Primary Key in a table automatically increment as a new row of data is entered? do i have to do it with a trigger?? if so what is the code behind it....what I have is a Applicant table, which holds the ApplicantID (<<<needs auto incremented), FirstName, LastName, Address, City, State, Zip, and PhoneNumber. I enter all the other information through visual web developer, and what I need to do when the hit submit on the form with the data i want to automatically set an id right there. any suggestions will help!
Hi all,I have a table where I have my ProdPK set up as Primary key, turned on "Is Identity" and set the Identity increment to 1. But each time I add a new item, the number incremented by 2... I have couple of other tables and they are all fine, just this particular table increased twice as it should. I check the setting against other tables and everything seems to be the same. By the way, this is adding the data to the table inside MS SQL Server Management Studio manually. I haven't done anything in the ASP.NET page yet. Thank you very much,Kenny.
Dear all, I am using SQL express 2005 in visual studio 2008. I would like to use Form View to insert new record in the table. There is a column call "id". I think it is too stupid to let user enter a unique identifier instead of generating by the system. I know how to generate a random integer number in a normal TextBox. However, when I edit the InsertItemTemplate, I cannot modified the value of that textbox. For example, i couldn't use "TextBox1.Text = temp;" here. How can I achieve to change this TextBox's value by the system that I would like to generate a random interger. Thanks a lot. Regards, Eric Chan
I was just wondering on a very simple database table with lets say a primary key set to columb ID and another columb lets say products, can you make the primary key automaticly increment its self whenever a new entry has been put in?For instance say I have this table set up with ID Being the primary KEY, Columb 1 = ID( INT ), Columb 2 = Products ( VarChar(50) ), and have the fields ID = 1, and products = my product.....and if a user inserts a new record say from a gridview or some sort of data entry the second ID Feild will automaticly be 2 and the products gets updated per user input.......I'm very sorry but I'm having a hard time putting this into words for some reason..umm basicly user adds something into the products feild and the ID field automaticly increments one number higher from the last one?ThanksAdam.
Ok - I have two tables that are relational. I have been inserted data into the tables because of testing. I also have been deleting data. My question is how do I reset the auto-incremented Primary key values. For example: Primary key of table one is bizID. Well there are only 3 record currently in the table. The bizIDs are 1-3. If I insert another record the bizID will be 88 because that was the next auto-incremented number. I obviously deleted the other records. I want to start the primary key value over from zero. How do I accomplish this? thnks
How to auto increment an alphanumeric Primary Key in SQL? :( Because I want to add something like this in the Primary Key, for example i'll add a new data with an alphanumeric value of ABC-0001, then I'll add another 1, and it auto increments to ABC-0002 and so on.. How can I do it? And if I'll add a new alpha character in the Primary Key field, for example DEF-0001, then I'll add another and it auto increments to 002, and so on, and it will go back to 0001 if i'll use another combination of alpha characters. for example, i'll add a new alpha character AAA, will it go back to 0001 or it will continue? T___T I hope u get my point.. I want my table to look like this if i have added the dataABC-0001ABC-0002DEF-0001DEF-0002AAA-0001then if il add a new 1, for example ABCit will auto increment to 0003 in the same field, it will look like this after addingABC-0001ABC-0002ABC-0003DEF-0001DEF-0002AAA-0001Will it be possible? :(
Hi guys,I followed the ASP.net official tutorial to create a DAL & Business Logic Layer (http://www.asp.net/learn/dataaccess/tutorial02cs.aspx). I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing? I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method? Thanks for any help!!! 1 public bool AddDevice(string make, string model) 2 { 3 //cannot have the same device entered twice! 4 if (Adapter.FillDeviceCountByMakeModel(make, model) == 1) 5 return false; 6 7 RepositoryDataSet.DevicesDataTable devices = new RepositoryDataSet.DevicesDataTable(); 8 RepositoryDataSet.DevicesRow device = devices.NewDevicesRow(); 9 10 device.make = make; 11 device.model = model; 12 13 devices.AddDevicesRow(device); << Error thrown Here! 14 int rows_affected = Adapter.Update(devices); 15 16 return rows_affected == 1; 17 }
I have imported a whole bunch of tables. Most of them have an ID (int) column. Is there a way to set the ID columns across all tables to auto increment Primary Keys in bulk?
I have a column that is not set to auto increment "IDX and Im inserting 800 part numbers but i want the IDX column to start at IDX 400 and increment 1 time per part number that is inserted. how can i accomplished that task.
EXAMPLE:
IDX PART#
400 abcde 401 fghi 402 jklm
etc. and so forth until the last part# will have IDX 1200...
I'm trying to create a column of numbers that increment by one.
I'm not able to use a #temptable in the application I'm using so I cannot use IDENTITY(int,1,1).
I want to add an Id column to this query:
Select distinct sd.name,ic.TABLE_SCHEMA,ic.TABLE_NAME from sys.databases sd cross join INFORMATION_SCHEMA.COLUMNS ic where sd.name = 'ODS1stage' order by TABLE_SCHEMA,TABLE_NAME
How can I accomplish this without creating a temp table? I would just alter the table and insert the numbers but there are 2000 rows.
i've posted in the wrong forum, so im posting here
hi, im having problems to import data from my excel to a sql table.
in the excel file i have exact the same fields that i have in the table excepts the primary key which is an auto increment. When i try to import data, an error that i can't insert nulls into my auto increment column.
I put enable identity insert in the edit options, but still doesnt work.
first to make column id like this(dll-123456) i made two column first is for three characters and second is int type and have a identity property but when combing two column i faced the problem of can not convert varchar to int so i made it in one column which datatype is varchar and default value is (dll-1) to test at first after that using substring to have the number and add 1 to it but it is activated for 2 row only ,i can not konw why ?
ALTER TRIGGER Trigger2 ON dbo.Supplier after INSERT--, UPDATE, DELETE */ AS declare @supplierid varchar(100); declare @sup varchar(20); declare @nbr int; select @nbr=nbr from inserted;
select @supplierid=supplierid from supplier where nbr=@nbr; if @supplierid is null select @supplierid='dll1';
select @sup=substring(@supplierid,4,1)+1;
if @sup <1 select @sup=1; --select @last=substring(@supplierid,1,3); insert into supplier(supplierid) values ('dll'+@sup) /* IF UPDATE () ...*/
so the column name is supplierid so what the error or if there ara another way for this primary key please state it. thank u in advance for assessting in that matter
Hello all,I'm using SS2K on W2k.I'v got a table say, humm, "Orders" with two fields in the PK:OrderDate and CustomerID. I would like to add an "ID" column whichwould be auto-increment (and would be the new PK). But, I would reallylike to have orders with the oldest OrderDate having the smallest IDnumber and, for a same OrderDate, I'd to have the smallest CustomerIDfirst. So my question is:How could I add an auto-increment column to a table and make it createits values in a particular order (sort by OrderDate then CustomerIDhere)?In the real situation, the table I want to modify has around 500krecords and the PK has 5 fields and I want to sort on three of them.Thanks for you helpYannick
Due to localization I have the need to make child tables, where there is a composite Primary Key, between the Id column and the LanguageSign column. On the parent table the Id column is Identity column with auto increment.
The problem is that during the select into query to copy columns from parent to child, this auto increment behaviour of the parent-Id is copied to the child-Id. However I do not want that, because the same Id will be used by different LanguageSign entries
Is there a way to use 'select into' without copying the auto increment, or is my only option to make a whole new column without auto increment on the child and copy the records?
btw I have used this statement
SET IDENTITY_INSERT MyTable
ON , so that inserting into the Id column is possible. I can see however that this does not take away the auto increment...
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 an MS SQL Server table with a Job Number field I need this field to start at a certain number then auto increment from there. Is there a way to do this programatically or within MSDE?
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 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.
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?
