1. I use Red Gate SQL Compare, but it's somewhat expensive
2. Link (temporarily?) the online and offline databases and write queries.
3. Create an Azure database and use its SQL Sync feature.
5.Move data via import and export, then merge appropriately
6. Other sync vendors: Idera,,


dchristal:  i need to achieve  this using program logic.
Can you give me some different logics to achieve  this ?
I need to better understand what you want to happen:
Do you want to update your local record?
                            Update the online database with this information?
                            Insert this as new information to the online database?

which record to you want to prevail? the online version or your local version?
Are you wanting to sync just one record or all of the records in both tables?



System went offline while user doing  transaction. So all the transactions went to offline database.
System needs to sync all the offline records to online db once the connection is restore. what are the different ways to achieve this ?
first: update production from offline where appropriate

update production  set [Loc#] = o.[Loc#], [Date] = o.[Date], [SaleAmt] = o.[SaleAmt}
from production p inner join offline o on p.[Trans#] = o.[Trans#]

second: insert missing offline records
assumptions: Many

insert into production ([Tran#], [Loc#] ,[ Date] ,[ Item#],[SaleAmt])
select [Tran#], [Loc#] ,[ Date] ,[ Item#],[SaleAmt] from offline
left outer join production on offline.[Tran#] = production.[Tran#] where p.[Tran#] is null
