Get Scope identity for multiple inserts - sql

Question

For table1 Inserted 3 records
It should get those three identities and it should insert 3 records in table3 (but it’s not happening- it inserts 3 records with same identity ie.last scope identity)
create table table1(ID INT identity(1,1),Name varchar(50))
insert into table1 values('Ram'),('Sitha'),('Laxman')
create table table1(ID INT identity(1,1),Name varchar(50))
create table table3(ID INT ,Name varchar(50))
insert into table2(Name)
select Name from table1
declare #id int;
set #id= (select scope_Identity())
begin
insert into table3(ID,Name)
select #id,Name from table2
end
select * from table2
select * from table3
How can get all identities to insert do I need to write a loop (or) do I need to Create a trigger.
Please give me a solution I am strugguling from past 4 hours.
Thanks in anvance

Answer 1

Use the OUTPUT clause to handle multi-row inserts:
INSERT INTO dbo.table2(Name)
OUTPUT inserted.ID, inserted.Name INTO table3
SELECT Name FROM dbo.table1;

Answer 2

You can use the OUTPUT clause to get the identity from any number of inserts.
create table table1(ID INT identity(1,1),Name varchar(50))
DECLARE #T1 Table (ID int, name varchar(50))
insert into table1
OUTPUT inserted.ID, Inserted.Name INTO #T1
values('Ram'),('Sitha'),('Laxman')

Answer 3

DECLARE #IdentityId INT,#Count INT=1
DECLARE #temp AS TABLE (Id INT IDENTITY ,Name NVARCHAR(100))
INSERT INTO #temp(Name)
SELECT Name FROM table1
WHILE #Count <=(SELECT COUNT(SId) FROM #temp)
BEGIN
INSERT INTO table2(Name)
SELECT Name FROM #temp
WHERE Id=#Count
SET #IdentityId = SCOPE_IDENTITY()
INSERT INTO tabel3(#IdentityId,Name)
SELECT 3, #IdentityId,1,GETDATE()
SET #Count=#Count+1
END
