Get-DbaDbState

Synopsis

Retrieves database state information including read/write status, availability, and user access mode

Description

Gets three key database state properties from sys.databases that DBAs frequently need to check:

• “RW” options: READ_ONLY or READ_WRITE (whether database accepts modifications)
• “Status” options: ONLINE, OFFLINE, EMERGENCY, RESTORING (database availability state)
• “Access” options: SINGLE_USER, RESTRICTED_USER, MULTI_USER (user connection restrictions)

This function is useful for quickly auditing database configurations across instances, especially when troubleshooting connectivity issues or preparing for maintenance operations. System databases (master, model, msdb, tempdb, distribution) are excluded by default since their states rarely change.

Returns an object with SqlInstance, DatabaseName, RW, Status, and Access properties for each user database.

Required Parameters

-SqlInstance

The target SQL Server instance or instances

Optional Parameters

-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

Specifies which user databases to check for state information. Accepts multiple database names as an array.
Use this when you need to audit specific databases rather than checking all databases on the instance.

-ExcludeDatabase

Specifies which user databases to exclude from the state check. Accepts multiple database names as an array.
Use this when you want to check most databases but skip specific ones, such as databases under maintenance.

-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.
