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?
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!

The primary key of my database (SQL server 2005) table is a uniqueidentifier.
I am using the following code to insert a row into my table:
myCommand.CommandText = sqlEvent.ToString(); //add the sql query to the command
myCommand.Connection = this.dbConnection; //add the database connection to the command
myCommand.ExecuteNonQuery(); //execute the insert query
I need to retrieve the GUID that is automatically generated when the insert command is executed.
Can someone help me? How do I get the GUID that is automatically generated? I have tried lots of things like using
string _id = (string)myCommand.ExecuteScalar();
and I am still stuck. I will really appreciate it if someone can refer me to some code sample.

I am inserting new records stored in SQL Server into a legacy MS Access application using SSIS. During the transformation, I need to get the ID MS Access assigned to the autoincrement column in the MS Access table I am inserting the row into. Is this possible? Can someone give me an example?
Thanks,

once upon a time someone told me how to do this, but i forget, and it was for classic asp..
so what im trying to do is create a new record (a workstation) and get back the auto generated ID (its not actually a GUID, its an int which is set to the identity) and then once i have that create other records (for external devices, different table) that will have a link to which machine they are attached to (that Id im looking to get returned)
I know this can be done in a two step process, create the record, query it for its id, and then slap that in my next insert statement for the external devices... but... i know there was a way to do it before and i assume there is a way to do it now...
anyone know how?
Thanks

I am trying to insert a record to based on the source below, however the GUID of GiftOcc_ID is being returned as zero's so the first record can be added but as it is defined as the primary Key and uniqueidentifier the next record fails with a duplicate entry. Basically how do I ensure that the GUID is created and not nulls. As you can see I am trying to use Newid() which I have inserted as a default value but that does not work. Also as it is a unique identifier the "is identity" is not available
Protected Sub CreateGiftOccasion(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Try
Dim null As New Nullable(Of Integer)
Dim da As New DataSet2TableAdapters.Gift_OccasionTableAdapter
Dim GiftOcc_ID As Guid
da.Insert(newid(), Occ_Type_Text.Text, Occ_Desc_Text.Text, Calendar1.SelectedDate, Calendar2.SelectedDate, 1)
Catch ex As Exception
Response.Write("Ooops")
End Try
End Sub
The code from the table adapter regarding inserts is:
<InsertCommand>
<DbCommand CommandType="Text" ModifiedByUser="False">
<CommandText>INSERT INTO [dbo].[Gift_Occasion] ([GO_ID], [Go_Type], [GO_Description], [GO_DateOn], [GO_DateOff], [GO_Active]) VALUES (@GO_ID, @Go_Type, @GO_Description, @GO_DateOn, @GO_DateOff, @GO_Active);

Hi,
anyone knows if there's an easy way to insert new GUIDs into uniqueidentifier cells when editing data in table on Management Studio Express? or Visual Studio 2005 Server Explorer? I can't find a shortcut, and copying from external tools is pain..
I suppose it's possible to build a VB macro in Visual Studio, would it work when editing table data?
Thanks in advance!
I am using SQL Server Data Tools for Visual Studio 2012. I have a very simple SSIS package with a Data Flow task that exports from an OLE DB Source to a tab-delimited unicode Flat File Destination and a Bulk Insert task that loads from the file. Both the Flat File Destination and Bulk Import are using the same code page. The Bulk Insert task is using the wide char format to read from the file. The process works fine with nvarchar and int columns, but when I add a unique identifier column it fails with "type mismatch or invalid character for the specified code page".

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
Johann

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.

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;

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,
Nick Goloborodko
I use Microsoft SQL Server and also I have several tables. One table has ID like PK, and name. ID use autoincrement number mode, and now when I want start form one but not from 156 or like that.
