What happens when autoincrement reaches its last value? Does my application crash? Will autoincrement wrap?
Let us assume I figure that my database table will be much smaller than 2^16 records. Since it will be nowhere near the limit, I select smallint (2 bytes wide) as my ID field. I set the seed value to -32,767. I set the increment value to 1. Over the course of actual useage, many records are added and deleted many times. Although I correctly anticipated that the number of records in my database is far less than 65,535, autoincrement has reached 65,535. What will happen next? Ideally I would like autoincrement to wrap and take the next unused value. But does it do that? Or does it freeze at the highest value? What happens?
I want to access sqlserver table properties from asp.net .How do i know that a table defined in sqlserver has autoincrement field or not.Actually i have to access all the tables in a database and execute different function for table with auto increment on and off. I am not being able identify this property from codes.Please help.thank you
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?
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
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 currently working asp.net with c# and inserting data from webpage into sqlserver 2000 data table. I have an auto increment ID in a table. Let's say 10 are inserted. Then you delete those 10. You add another and the auto increment sets the id at 11. How can I get that table to start back to 0? Plz help me and give code for increment id programmatically using c#. Thanks in Adv,
I have designed a simple table named "test" with ID as primary key and Name as a string data. When I delete a row from the table and insert a new row.. then the ID column increments itself by 1.. for eg : if i have 2 rows in my table
1 Karthik 2 you
if I delete the 2nd row and insert your name in the place of 2nd row.. actually my rows shows
I have a table with two primary key fileds. I will be running a process to populate the data into the table.For each process the first field is constant and second field is auto increment one.
My statements are insert into select ** from ** type one.
How do I auto increment second filed per run. Any delivered function available or any suggestion Pl.................
hi experts, i have a table that i did a lot of work with, now i want to add a column and this column has to automatically incremented, now if i change it and save then it will replace my table data to 0 and i do not want to lose all the data, is there a way to insert values like 1 2 3 4 5 6 to this table(Locations) without changing the other data?
i just want to know tht i have table which have large record almost 7 lakh round about , when i set auto increment on it gives me timeout error, is der any easy way to ON auto increment ??
I have a requirement to read a value from table and increment it by 1. There can be multi-threads doing the same operation and would need a ROW LOCK so that read and write both are atomic. How can i put an exclusive lock on the row before I read the value from the table.
CREATE TABLE [dbo].[tblOnboardingSequence]( [OnboardingSequenceID] [uniqueidentifier] NOT NULL, [Name] [nvarchar](255) NOT NULL, [NextNumber] [bigint] NOT NULL, CONSTRAINT [PK_OnboardingSequence] PRIMARY KEY CLUSTERED( [OnboardingSequenceID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]
GO
My Stored Procedure has below logic
DECLARE @NextNumber BIGINT ----------- Acquire row lock here SELECT @NextNumber = NextNumber FROM tblOnboardingSequence WHERE Name = 'TPO' UPDATE tblOnboardingSequence SET NextNumber = @NextNumber + 1 WHERE Name = 'TPO' ----------- Release row lock here
I would like to have a row lock for the row having Name "TPO" before SELECT query and release after UPDATE query. What si the best way to deal with this?
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 had a strange problem today with one of the identity fields in a frequently used table. It appears that the Identity column for a table had stopped incrementing after it reached 2147483585. Since I had inherited this table, I am not sure if the identity column type has been modified from int to numeric, but the current type is Numeric (9) which is 19 precision and 0 scale value.
When resetting the seed to 1, it started working. I tried creating a temp table with numeric value and it increments well beyond billions with no problems.
Has anyone encountered this? Any best practices around defining Identity data type (ie. use int or bigint and avoide Numeric)? Thanks NS
I need to have a script where it ask the user for a value, the script will search for all records that match the value. Then it will display the numbers of records found and ask the user to enter a different value. The rest of the script will use this new value and increment by 1 n times as the number of records found. I started the script where it will ask for "HANDLE" and display the number of records found with that "HANDLE"
declare @HANDLE as varchar(30) declare @COUNT as varchar(10) declare @STARTINV as varchar(20)
set @HANDLE = ?C --This is the parameter to search for records with this value set @STARTINV = ?C --User will input the starting invoice number SELECT COUNT as OrderCount FROM SHIPHIST where HANDLE = @HANDLE
I just can't figure out how to proceed to use the entered invoice # and increment by 1 until it reach the number of records found.
This will be the end results:
Count=5 --results from query STARTINV=00010 --Value entered by user
i have a table for storing username and password. the following are the fields in table ID -int UserName-nvarchar(50) Password-nvarchar(50)

Hi All I am using SQL server Database in one of my table there is a column which is set to Identity=Yes i.e., The ID is increment by one on every insert and if the insertion failed then the id generated goes off then in the next generation it uses new id ..........EXfirst insertion id=1 then in the second insertion if while adding data to other rows if i get some error then the id 2 is not used and when i correct the error and insert it then id=3? can any one give me the solution for this and NextWhen i delete the datafrom the table see the ids are upto 20 and i delete all the records from the table after insertion of new record the id will be 21plese help me in this
This may sound quite easy for you, however I am a newbie in SQL.
So I have an identity field, which I wish to increment automatically every time I do an insert. However the starting integer has to be the MAX value from another table.
So for example I am doing an insert in a #temp table INSERT INTO #temp(name, surname) SELECT name, surname from table1
Now the personId of the #temp table has to start from the MAX of table2 Ie SELECT MAX(personId) from table2
The SELECT MAX(personId) from table2 can also be NULL, ie the first time I am inserting, so I also have to cater for this scenario.
Hi all, i am deleting rows of a table and reinserting new ones. This table has an auto increment primary key. what is the function used to set it to zero each time i delete the rows in order to rebegin counting from 1 when i refill the table. Thanks in advance...
I created a new table in sql server 2005. Primary key is autoincrement value of 1. But when I insert the row, it increments by 4. It goes like 1, 5, 9 etc..what could be the problem ?how can I correct it? Do I need to reseed it? Thanks!!
looking for necessary syntax to alter table id to autoincrement adding identity statement, not sure on syntax for seed an increment, or if it is possible at all.
I noticed in SQL ODBC API reference that SQLGetTypeInfo would return true for AUTO_INCREMENT if a smallint field is defined as autoincrement. Is there a simple way to set a field autoincrement thru the SQL Server`s front end?
I have 2 tables: 1. CommandCode( id AutoIncrement_integer, name string ) 2. FooCode( FooID integer, CommandCodeID integer)
I have the following stored procedure
PROCEDURE InsertRows( CodeName VARCHAR ) INSERT INTO CommandCode ( name ) VALUES (CodeName)
Now right here I need to INSERT INTO the "FooCode" table using the same ID that was just added to the CommandCode table. How can I retrieve the last inserted autoincrement value for "id" in the CommandTable without doing SELECT id FROM CommandCode WHERE name = CodeName
END PROCEDURE
Is there an easy way to do what I described above? If possible I want it to comply with SQL standards (e.g. no MS SQL specific code)
