Get-DbaReplArticleColumn

Synopsis

Retrieves column-level replication configuration details for SQL Server publication articles.

Description

Returns detailed information about which columns are included in replication articles, helping DBAs audit replication configurations and troubleshoot column-specific replication issues. This is particularly useful when working with vertical partitioning scenarios where only specific columns from source tables are replicated to subscribers, or when investigating why certain columns aren’t appearing in replicated data.

Optional Parameters

-SqlInstance

The target SQL Server instance or instances.

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Database

Filters results to specific database(s) containing publications. Accepts wildcards for pattern matching.
Use this when you need to focus on replication columns from particular databases rather than scanning all databases on the instance.

-Publication

Filters results to specific publication(s) within the specified databases. Accepts wildcards for pattern matching.
Use this when auditing column replication configuration for particular publications or troubleshooting column-level issues in specific publications.

-Article

Filters results to specific article(s) within the publications. Accepts wildcards for pattern matching.
Use this when you need to examine column replication details for particular tables or views that are published as articles.

-Column

Filters results to specific column name(s) across all matched articles. Case-sensitive exact match.
Use this when investigating whether specific columns are included in replication or troubleshooting missing columns in subscriber databases.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with “sea of red” exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this “nice by default” feature off and enables you to catch exceptions with your own try/catch.
