#ValidationTags#Messaging,FlowControl,Pipeline# function Get-DbaDbState { <# .SYNOPSIS Gets various options for databases, hereby called "states" .DESCRIPTION Gets some common "states" on databases: - "RW" options : READ_ONLY or READ_WRITE - "Status" options : ONLINE, OFFLINE, EMERGENCY, RESTORING - "Access" options : SINGLE_USER, RESTRICTED_USER, MULTI_USER Returns an object with SqlInstance, Database, RW, Status, Access .PARAMETER SqlInstance The SQL Server that you're connecting to .PARAMETER SqlCredential Credential object used to connect to the SQL Server as a different user .PARAMETER Database The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER 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. .NOTES Tags: Database Author: niphlod Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDbState .EXAMPLE Get-DbaDbState -SqlInstance sqlserver2014a Gets options for all databases of the sqlserver2014a instance .EXAMPLE Get-DbaDbState -SqlInstance sqlserver2014a -Database HR, Accounting Gets options for both HR and Accounting database of the sqlserver2014a instance .EXAMPLE Get-DbaDbState -SqlInstance sqlserver2014a -Exclude HR Gets options for all databases of the sqlserver2014a instance except HR .EXAMPLE 'sqlserver2014a', 'sqlserver2014b' | Get-DbaDbState Gets options for all databases of sqlserver2014a and sqlserver2014b instances #> [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseLiteralInitializerForHashtable", "")] [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [Alias("Credential")] [PSCredential] $SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [Alias('Silent')] [switch]$EnableException ) begin { $DbStatesQuery = @' SELECT Name = name, Access = user_access_desc, Status = state_desc, RW = CASE WHEN is_read_only = 0 THEN 'READ_WRITE' ELSE 'READ_ONLY' END FROM sys.databases '@ } process { foreach ($instance in $SqlInstance) { Write-Message -Level Verbose -Message "Connecting to $instance" try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $dbStates = $server.Query($DbStatesQuery) $dbs = $dbStates | Where-Object { @('master', 'model', 'msdb', 'tempdb', 'distribution') -notcontains $_.Name } if ($Database) { $dbs = $dbs | Where-Object Name -In $Database } if ($ExcludeDatabase) { $dbs = $dbs | Where-Object Name -NotIn $ExcludeDatabase } # "normal" hashtable doesn't account for case sensitivity $dbStatesHash = New-Object -TypeName System.Collections.Hashtable foreach ($db in $dbStates) { $dbStatesHash.Add($db.Name, [pscustomobject]@{ Access = $db.Access Status = $db.Status RW = $db.RW }) } foreach ($db in $dbs) { $db_status = $dbStatesHash[$db.Name] [PSCustomObject]@{ SqlInstance = $server.Name InstanceName = $server.ServiceName ComputerName = $server.ComputerName DatabaseName = $db.Name RW = $db_status.RW Status = $db_status.Status Access = $db_status.Access Database = $server.Databases[$db.Name] } | Select-DefaultView -ExcludeProperty Database } } } end { Test-DbaDeprecation -DeprecatedOn "1.0.0" -EnableException:$false -Alias Get-DbaDatabaseState } } |
