Introduction

We should follow certain best practices while designing objects in SQL Server. For example, a table should have primary keys, identity columns, clustered and non-clustered indexes, constraints to ensure data integrity and performance. Even we follow the best practices, and we might face issues such as 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.

Suppose your SQL table contains duplicate rows and you want to remove those duplicate rows. Many times, we face these issues. 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. We need to follow specific methods to clean up duplicate data. This article explores the different methods to remove duplicate data from the SQL table.

This software offers a solution to users who want to delete duplicate entries in MS SQL Server tables. Simply specify which fields (columns) to use as criteria. All redundant entries are eliminated, leaving one unique entry. This software will save you hours of time by automatically sorting through large quantities of data. SQL Server 2000 or higher required.
