Is their anybody knows how to make field in Sql Server autoincrement?
pls. help me.
Hi All,
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.
can anyone help?
Thanks

How can I know that a column is auto incremented or not? What are the commands used to know this??

Is it possible to implement autoincrement with SQLexpress edition?
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.
View 2 Replies View RelatedI 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?

Hey guys,
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)
Thanks!
Hi all!
Does anyone knows how to get if a column is autoincrement or not, using the DatabaseMetaData in java, or using de JTurbo driver for it?
Is there any other way to figure this out?
:confused:
Thank you very much in advance for any replies.
Hi All,

Already thanx.

I am creating a trigger in SQL Server that will activate when my Athelete table has something "Inserted"
So far it works except for the fact that it won't insert a null into the Equipment_ID field. I need it to autoincrement, or do the last number + 1...
CREATE TRIGGER TRG_NEW_EQUIPMENT1
ON ATHLETE AFTER INSERT
AS
BEGIN
INSERT INTO Equipment Equipment_ID, Equipment_Model, Equipment_Year, Equipment_Brand, Equipment_Color, Equipment_Condition_Rating)
VALUES ('Big Spin','2016','K2','Blue','5')
END;
GO
Hi,I'm enclosed a snippet of test code which highlights my problem. The Storedprocedure insertValue should insert text into the parent, then insert othertext into the child table but the 2 tables should auto increment in sync(i.e. so that they both end up with the same id numbers). I've tried takingthe auto increment out of the child table but then I don't know how to getthe right parent id into the child table.Any advice appreciated - this is my first database, so I'm just in thelearning process really. Code follows:CREATE TABLE Parent(id INTEGER DEFAULT AUTOINCREMENT,parenttext VARCHAR(16),PRIMARY KEY (id))!CREATE TABLE Child(childID INTEGER INTEGER DEFAULT AUTOINCREMENT,childtext VARCHAR(16),FOREIGN KEY (childid) REFERENCES Parent(id),PRIMARY KEY (childID))!CREATE PROCEDURE insertValues(in p VARCHAR(16), in c VARCHAR(16))BEGINinsert into parent (parenttext) values (p);insert into child (childtext) values (c);END!call insertValues('from parent', 'from child')!select * from parent, child where parent.id = child.childid!

View 4 Replies View RelatedHi,
I'm currently writing a small application that is using SQL Server as a back-end database. A part of my database looks something lie the following:
Tables:
Orders(OrderId[int, PK], OrderDescription[varchar] etc...)
OrderLines(OrderId[int, PK, FK], OrderLineId[int, PK], etc...)
What I need to achieve is - everytime that a new line is inserted into an orderlines table part of the primary key will be the OrderId and the OrderLineId should be auto-incremented from 1 for each OrderId in the OrderLines table.
I know i can do this manually in my program, but i'm just wondering if theres a way to achive this in SQL Server?
Thanks,

Hy! I am a beginner in SQLServer and I have to design a database with a lot of tables (30-50 tables). I have to choose a primary key for every table between an autoincrement and a GUID. If I choose autoincrement after an insert statement (from the client) I will have to go back to the server to get the value of the primary key which is a waste of time. On the other hand if I choose a GUID I can create the guid from the client and send him with the other values of the new row to the server and I have not to go back to the server. I am aware of the disk space of a guid field so which is the best for me: GUID or AUTOINCREMENT? Thank you!

Hi, im trying to insert values into 2 different tables. The primary key in the first table is an auto increment field, which is then the foreign key in the 2nd table.Is there any way to retrieve the autogenerated value before performing the second insert. I have done some searching on the matter, but to no avail.I tried using LAST_INSERT_ID() but i get the error message that it is not a recognized function name. The other option is using @@identity but i cant see how to put that into my SQL statement.Can anyone help please.Thanks in advanceGareth
View 2 Replies View RelatedI'm getting reports of a strange problem with an ASP.NET application I've written. I've checked the database tables and the problem is definately a strange one, and one I've yet to pin down or even recreate.On this system, clients can type in their details through a .NET 2.0 wizard. At the end of the wizard their data is stored on the database using several linked tables. It's always worked for me and my client, but now when their clients are using it, some of the data is missing. The problem, however, is that I can't see how it can just disappear and was wondering if someone could shed some light on SQL.There are two tables that are baffling me. Their structure is like this:Table 1id - autoincrement columnnameaddressetc ...Table 2id - autoincrement columncontactDetailsetc ...The contactDetails column on table 2 is taken from the id column of table 1. When a new record is added to table 1, it obviously increments the id for the new row, then it takes this id (using scope_identity()) and writes it to the contactDetails column of table 2 when a new row is added to that table. All straightforward enough.However, for some reason, some of the new rows in table 1 are missing and yet, the contactDetails column of table 2 contains the ids of those missing rows. How is that even possible? Can there be situations where MSSQL 2000 will generate/return an id even when it has failed to write to the database?

Im still learning my way around SQL and queries and i was wondering :
How do you get a SQL Table to autoincrement a Guid? (is it "Is Identity?" or "RowGuid"....)
How would i create a new row with a new Guid, and insert into the values i want without specifying the Guid?
Hi,
I have a table (Table1) with an autoincrement column (sql server 2005) and in my asp .net code (c#) the user can delete a row (record) in gridview (by clicking on delete link).
The problem is that every time if the user adds a new record in gridview the new row has a wrong number.
What I mean is:
Table1 has two columns: ID and Category
ID Category1 test12 test23 test3 -> delete this row
Now insert a new row:
ID Category1 test12 test24 test3 -> ID is 4, but it should be 3
Could anyone help me please?
Thank you in advance!

Does anybody know the function or any other way in MS SQL Server 2000 or in MS Access or in MS FoxPro that I can get an increment record position in a view?
For example let’s say that I have a table with only one field named persons. The table has three records person1, person2 and person3. What is the way in MS SQL Server 2000 or in MS Access or in MS FoxPro of retrieving the records in a view with an extra field named for example recno which will indicate the record autoincrement number in the view as it is below?
recno persons
1person1
2person2
3person3

In SQL Server 2000, I'm looking for input as to how to set up primary keys (PKs).
Is it safe to use the IDENTITY feature using AUTOINCREMENT as a setting for a PK, or is it best to generate my own and check for dups?
My concern is whether SQL Server at any point will taint the numbers used as the PK -- because as you know, these PKs are going to wind up linking into (relating into) other tables (e.g. client orders).
Certainly it's vital that the clientID not get lost/changed during any regular DB maintenance or use.
Any input would be appreciated.
Is there a way to use the SQL alter table command to modifiy the identity
increment?
Hi just new here in the forum i have a question
is it a good practice to use autoincrement fields in an access database for master and detail? and for unique record identification. if not please tell why..
im currently using access and with autoincrement for unique record identification and for master and detail.. then there is a possibilities to transfer from access to mssql. will i encounter problems when migrating since i am using an autoincrement fields
in mssql is there an autoincrement fields like access?
dont be harsh ok.. just anoob trying to learn. :eek:
Running an insert into a table where a column has a constraint for unique records
i have an autonumber pk that increments but numbers are not in sequence etc. if constraints are found
e.g.
10 records are inserted but only 2 are unique but there is a gap of 8 in the PK autoincrement value (it's like the unique records that were not inserted are still being recorded by the autoincrement).
I'm using a SQL 2008 database on a SQL 2012 hosted server. I have an autoincrement ID for locations that my members create. These go up by 1.... eg. 9400, 9401, 9402.
Tonight a member attempted to make a new location and the ID went from 9407, 9408 and JUMPED to 10408. Any subsequent creations only continue from 10408 onwards.
What happened here? 9409 to 10407 just aren't available.
