INSERT INTO files  title  VALUES   whatever     SELECT   FROM files WHERE id   SCOPE IDENTITY      Is the safest bet since there is a known issue with OUTPUT Clause conflict on tables with triggers  Makes this quite unreliable as even if your table doesn t currently have any triggers - someone adding one down the line will break your application  Time Bomb sort of behaviour   See msdn article for deeper explanation   http   blogs msdn com b sqlprogrammability archive 2008 07 11 update-with-output-clause-triggers-and-sqlmoreresults aspx

There are many ways to exit after insert     When you insert data into a table  you can use the OUTPUT clause to   return a copy of the data that   s been inserted into the table  The   OUTPUT clause takes two basic forms  OUTPUT and OUTPUT INTO  Use the   OUTPUT form if you want to return the data to the calling application    Use the OUTPUT INTO form if you want to return the data to a table or   a table variable    DECLARE  MyTableVar TABLE  id INT NAME NVARCHAR 50     INSERT INTO tableName     NAME       OUTPUT INSERTED id INSERTED Name INTO  MyTableVar VALUES       test          IDENT CURRENT  It returns the last identity created for a particular table or view in any session   SELECT IDENT CURRENT  tableName   AS  IDENT CURRENT    SCOPE IDENTITY  It returns the last identity from a same session and the same scope  A scope is a stored procedure trigger etc   SELECT SCOPE IDENTITY   AS  SCOPE IDENTITY         IDENTITY  It returns the last identity from the same session   SELECT   IDENTITY AS    IDENTITY

Parameter order in the connection string is sometimes important    The Provider parameter s location can break the recordset cursor after adding a row  We saw this behavior with the SQLOLEDB provider   After a row is added  the row fields are not available  UNLESS the Provider is specified as the first parameter in the connection string  When the provider is anywhere in the connection string except as the first parameter  the newly inserted row fields are not available  When we moved the the Provider to the first parameter  the row fields magically appeared

Entity Framework performs something similar to gbn s answer   DECLARE  generated keys table  Id  uniqueidentifier   INSERT INTO Customers FirstName  OUTPUT inserted CustomerID INTO  generated keys VALUES  bob     SELECT t  CustomerID  FROM  generated keys AS g     JOIN dbo Customers AS t     ON g Id   t CustomerID WHERE   ROWCOUNT  gt  0   The output results are stored in a temporary table variable  and then selected back to the client  Have to be aware of the gotcha      inserts can generate more than one row  so the variable can hold more than one row  so you can be returned more than one ID   I have no idea why EF would inner join the ephemeral table back to the real table  under what circumstances would the two not match    But that s what EF does    SQL Server 2008 or newer only  If it s 2005 then you re out of luck

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

You can use scope identity   to select the ID of the row you just inserted into a variable then just select whatever columns you want from that table where the id   the identity you got from scope identity    See here for the MSDN info http   msdn microsoft com en-us library ms190315 aspx

The best and most sure solution is using SCOPE IDENTITY     Just you have to get the scope identity after every insert and save it in a variable because you can call two insert in the same scope   ident current and   identity may be they work but they are not safe scope  You can have issues in a big application    declare  duplicataId int   select  duplicataId      SELECT SCOPE IDENTITY      More detail is here Microsoft docs

There are multiple ways to get the last inserted ID after insert command      IDENTITY   It returns the last Identity value generated on a Connection in current session  regardless of Table and the scope of statement that produced the value SCOPE IDENTITY    It returns the last identity value generated by the insert statement in the current scope in the current connection regardless of the table  IDENT CURRENT    TABLENAME       It returns the last identity value generated on the specified table regardless of Any connection  session or scope   IDENT CURRENT is not limited by scope and session  it is limited to a specified table     Now it seems more difficult to decide which one will be exact match for my requirement   I mostly prefer SCOPE IDENTITY     If you use select SCOPE IDENTITY   along with TableName in insert statement  you will get the exact result as per your expectation   Source   CodoBee
