SQL Server Replication Issues with Computed Columns
Introduction: In SQL Server, computed columns are a powerful feature that allows you to create virtual columns with values calculated on-the-fly based on other columns' data. While computed columns can simplify data retrieval and improve data consistency, they can also pose challenges when it comes to replication. This blog post explores the issues associated with computed columns in SQL Server replication and presents solutions to tackle them. Understanding Computed Columns: A computed column is essentially a virtual column within a table. It does not physically store its data in the table unless explicitly marked as "PERSISTED." Instead, a computed column derives its value based on an expression that can use data from other columns in the same table. Challenges in Replication: Replication in SQL Server involves copying data from one database (the publisher) to one or more destination databases (subscribers). However, when dealing with computed columns, replication can e
