SQL Server - Best Way to Get Identity of Inserted Row

SQL Server - Best way to get identity of inserted row?

• @@IDENTITY returns the last identity value generated for any table in the current session, across all scopes. You need to be careful here, since it's across scopes. You could get a value from a trigger, instead of your current statement.

• SCOPE_IDENTITY() returns the last identity value generated for any table in the current session and the current scope. Generally what you want to use.

• IDENT_CURRENT('tableName') returns the last identity value generated for a specific table in any session and any scope. This lets you specify which table you want the value from, in case the two above aren't quite what you need (very rare). Also, as @Guy Starbuck mentioned, "You could use this if you want to get the current IDENTITY value for a table that you have not inserted a record into."

• The OUTPUT clause of the INSERT statement will let you access every row that was inserted via that statement. Since it's scoped to the specific statement, it's more straightforward than the other functions above. However, it's a little more verbose (you'll need to insert into a table variable/temp table and then query that) and it gives results even in an error scenario where the statement is rolled back. That said, if your query uses a parallel execution plan, this is the only guaranteed method for getting the identity (short of turning off parallelism). However, it is executed before triggers and cannot be used to return trigger-generated values.

SQL Server - Return value after INSERT

No need for a separate SELECT...

INSERT INTO table (name)
OUTPUT Inserted.ID
VALUES('bob');

This works for non-IDENTITY columns (such as GUIDs) too

Select id from last inserted row

You can use the SCOPE_IDENTITY() in your stored procedure to get last inserted record id.

SELECT SCOPE_IDENTITY() :- It will returns the last identity value inserted into an 
identity column in the same scope.

SELECT @@IDENTITY :- @@IDENTITY will return the last identity value entered 
into a table in your current session. 

SELECT IDENT_CURRENT(‘tablename’) :- IDENT_CURRENT is not limited by scope and
session; it is limited to a specified table. 

There are other options also such as

1. Select Top 1 id From Table Order by id desc

2. SELECT max(id) FROM table

How can I reliably get identity ID of a row inserted into a different database

Use the output clause:

declare table @ids (id int);
insert into DB_B.dbo.CustAddress
    output inserted.id into @ids
    values (@newAddress);

select *
from @ids;

Get the last inserted row ID (with SQL statement)

If your SQL Server table has a column of type INT IDENTITY (or BIGINT IDENTITY), then you can get the latest inserted value using:

INSERT INTO dbo.YourTable(columns....)
   VALUES(..........)

SELECT SCOPE_IDENTITY()

This works as long as you haven't inserted another row - it just returns the last IDENTITY value handed out in this scope here.

There are at least two more options - @@IDENTITY and IDENT_CURRENT - read more about how they works and in what way they're different (and might give you unexpected results) in this excellent blog post by Pinal Dave here.

How get last inserted ID in SQL Server 2012

Assuming table is

create table test
(
    id int IDENTITY(1,1) PRIMARY KEY
    , testData varchar(100) NOT NULL
)

this works

INSERT INTO dbo.Test (testData) VALUES ('test')
SELECT @@IDENTITY AS ID

as does this (better answer)

INSERT INTO dbo.Test (testData) VALUES ('test')
SELECT SCOPE_IDENTITY() AS ID

I don't have enough information to know why yours does not work. It is probably in the table structure? I would need more information to answer this.

How to get Identity value from SQL server after insert record

Append SELECT SCOPE_IDENTITY(); to your normal INSERT statement:

Replace the last concatenation with:

SQLString += "; SELECT SCOPE_IDENTITY();"

Then to retrieve the ID:

int ID = Convert.ToInt32(command.ExecuteScalar());
