Replication of the current Identity - sql

Question

I have a table Temp_Identity with a single IDENTITY column.
When we are doing the replication, data from this table is correctly replicated. But its current identity is not replicated.
This means, the current identity of that table in the production database is 10. But in the replication database, it is still 1.
Is there any method to solve this automatically without doing manually?
Table Structure
CREATE TABLE Temp_Identity
(
ID Int IDENTITY(1,1) Primary Key,
Name Varchar(100)
)
When I insert the following values in Production DB ,It is correctly effected inn Replication DB
INSERT INTO Temp_Identity
SELECT 'AA'
UNION ALL
SELECT 'BB'
UNION ALL
SELECT 'CC'
When i Insert the given row from the Replication DB,I got a error.
INSERT INTO Temp_Identity
SELECT 'DD'
It is because,In the Replication DB,the table contains that three rows,When we do the above insertion,the value for the ID column is '1' (Current Identity of that table in Production DB is 3.But in the Replication DB is 1. It should be same as that of Production DB). It is already exists in table.So the Primary Key error raised.

Answer 1

Probably this approach may work in this scenario.
create table tmptbl (ID int identity(1,1) Primary key clustered, name varchar(100))
insert into tmptbl
Select 'A' union all
Select 'B' union all
Select 'C'
Create back up table
create table tmptbl_BCK (ID int identity(1,1) Primary key clustered, name varchar(100))
insert into tmptbl_BCK
select name from tmptbl
delete from tmptbl_BCK --to create the scenario this will remove the previous identity keys and create new keys for new insert.
insert into tmptbl_BCK
select name from tmptbl
select * from tmptbl (in original table)
ID name
1 A
2 B
3 C
select * from tmptbl_BCK
ID name
10 A
11 B
12 C
You can take help of Set Identity Insert option to make sure you have same identity in these tables. First make sure to delete the rows.
delete from tmptbl_BCK
set identity_insert tmptbl_BCK On
insert into tmptbl_BCK (ID, Name) select ID, name from tmptbl
set identity_insert tmptbl_BCK Off
select * from tmptbl_BCK
Output you get:
ID name
1 A
2 B
3 C
Now if you want to have same identity value (in your replication table) as production then you do in this way.
Declare #reseedvalue int = (Select IDENT_CURRENT('tmptbl')) --though it gives you the last inserted value, next time it reseeds it will be 4 in your production table and replication table
--select #reseedvalue
--to reseed based on your production table
DBCC CHECKIDENT ('tmptbl_BCK', RESEED, #reseedvalue)
--test if it creates 4 in your back up table
insert into tmptbl_BCK
select 'D'
select * from tmptbl_BCK
