We use another conditional split to compare value of equivalent columns in source and destination.

ssis updating data-37

Hi, nice explanation am tried with your solution its working fine.

BUT am getting million of records after union all from different local dbs after that sorting and sending to merge join its blocking at sorting can you tell me any better way Hi Anudeep, the blocking part of your package as you've mentioned is Sort Transformation.

UPSERT is about Update existing records, and Insert new records.

I don't recommend using Sort Transformation because it first load all records in memory and then start sorting them which cause performance issues and blocking.

The best way is always sorting with order by clauses in source t-sql commands.

Regards, Reza Hi, Above creating packages is good but merge join and update process took lot of times in case of mine tables have atleast 15K rows at Source and same as dest.. I want fast way to execute thease package within 1 min is it posible?

Please guide Hi Nilesh, There are other methods to do that, each method has pros and cons.

the best method in terms of performance and speed of running the etl, is using Merge command of T-SQL.

There is also an option for using Lookup component, which performs better especially if reference table is small.

Actions that I make and assumptions: - In the target table, I place all persons in the origin and still not in the destination.
