It opens the Sort output data viewer at the Data flow task. The overall SSIS package looks like below.Įxecute the package to perform SQL delete operation. To view the distinct data, right-click on the connector between Sort and Multicast. We only want to check that sort operator is doing the task for us or not. We can add SQL Server destinations to store the data after removing duplicate rows. Once we click OK, it returns to the data flow tab, and we can see the following SSIS package. It performs the SQL delete activity in the SSIS package. Let’s put a tick in this checkbox andĬlick ok. It will do the task of removing duplicate rows for us from the source data.

The sort order, we can choose the column sort order.

Let’s create a sample Employee table and insert a few records in it. This article explores the different methods to remove duplicate data from the SQL table. We need to follow specific methods to clean up duplicate data. It is a best practice as well to use the relevant keys, constrains to eliminate the possibility of duplicate rows however if we have duplicate rows already in the table. Suppose your SQL table contains duplicate rows and you want to remove those duplicate rows. We might also get these data in intermediate tables in data import, and we want to remove duplicate rows before actually inserting them in the production tables. Even we follow the best practices, and we might face issues such as duplicate rows. For example, a table should have primary keys, identity columns, clustered and non-clustered indexes, constraints to ensure data integrity and performance.

We should follow certain best practices while designing objects in SQL Server.

This article explains the process of performing SQL delete activity for duplicate rows from a SQL table.
