function Get-DbaDatabase { <# .SYNOPSIS Gets SQL Database information for each database that is present in the target instance(s) of SQL Server. .DESCRIPTION The Get-DbaDatabase command gets SQL database information for each database that is present in the target instance(s) of SQL Server. If the name of the database is provided, the command will return only the specific database information. .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential PSCredential object to connect as. If not specified, current Windows login will be used. .PARAMETER Database The database(s) to process. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude. .PARAMETER ExcludeAllUserDb Returns only databases that are not User Databases. This parameter cannot be used together with -ExcludeAllSystemDb. .PARAMETER ExcludeAllSystemDb Returns only databases that are not System Databases. This parameter cannot be used together with -ExcludeAllUserDb. .PARAMETER Status Returns SQL Server databases in the status(es) listed. Could include Emergency, Online, Offline, Recovering, Restoring, Standby or Suspect. .PARAMETER Access Returns SQL Server databases that are Read Only or Read/Write. To collect both, don't use this parameter. .PARAMETER Owner Returns list of databases owned by the specified logins. .PARAMETER Encrypted Returns list of databases that have TDE enabled from the SQL Server instance(s) executed against. .PARAMETER RecoveryModel Returns list of databases in listed recovery models (Full, Simple or Bulk Logged). .PARAMETER NoFullBackup Returns databases without a full backup recorded by SQL Server. Will indicate those which only have CopyOnly full backups. .PARAMETER NoFullBackupSince DateTime value. Returns list of databases that haven't had a full backup since the passed in DateTime. .PARAMETER NoLogBackup Returns databases without a Log backup recorded by SQL Server. Will indicate those which only have CopyOnly Log backups. .PARAMETER NoLogBackupSince DateTime value. Returns list of databases that haven't had a Log backup since the passed in DateTime. .PARAMETER IncludeLastUsed Returns the Last used read and write Times for the Database using the sys.dm_db_index_usage_stats DMV which will show the information since the last restart of SQL .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Tags: Database Original Author: Garry Bargsley (@gbargsley | http://blog.garrybargsley.com) Author: Klaas Vandenberghe ( @PowerDbaKlaas ) Author: Simone Bizzotto ( @niphlod ) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Get-DbaDatabase .EXAMPLE Get-DbaDatabase -SqlInstance localhost Returns all databases on the local default SQL Server instance .EXAMPLE Get-DbaDatabase -SqlInstance localhost -ExcludeAllUserDb Returns only the system databases on the local default SQL Server instance .EXAMPLE Get-DbaDatabase -SqlInstance localhost -ExcludeAllSystemDb Returns only the user databases on the local default SQL Server instance .EXAMPLE 'localhost','sql2016' | Get-DbaDatabase Returns databases on multiple instances piped into the function .EXAMPLE Get-DbaDatabase -SqlInstance SQL1\SQLExpress -RecoveryModel full,Simple Returns only the user databases in Full or Simple recovery model from SQL1\SQLExpress .EXAMPLE Get-DbaDatabase -SqlInstance SQL1\SQLExpress -Status Normal Returns only the user databases with status 'normal' from sql instance SQL1\SQLExpress .EXAMPLE Get-DbaDatabase -SqlInstance SQL1\SQLExpress -IncludeLastUsed Returns the databases from sql instance SQL1\SQLExpress including the last used information from the sys.dm_db_index_usage_stats DMV .EXAMPLE Get-DbaDatabase -SqlInstance SQL1\SQLExpress,SQL2 -ExcludeDatabase model,master Returns all databases except master and model from sql instances SQL1\SQLExpress and SQL2 .EXAMPLE Get-DbaDatabase -SqlInstance SQL1\SQLExpress,SQL2 -Encrypted Returns only encrypted databases from sql instances SQL1\SQLExpress and SQL2 .EXAMPLE Get-DbaDatabase -SqlInstance SQL1\SQLExpress,SQL2 -Access ReadOnly Returns only read only databases from sql instances SQL1\SQLExpress and SQL2 .EXAMPLE Get-DbaDatabase -SqlInstance SQL2,SQL3 -Database OneDB,OtherDB Returns databases 'OneDb' and 'OtherDB' from sql instances SQL2 and SQL3 if the databases exist on those instances #> [CmdletBinding(DefaultParameterSetName = "Default")] [OutputType([Microsoft.SqlServer.Management.Smo.Database[]])] Param ( [parameter(Position = 0, Mandatory = $true, ValueFromPipeline = $True)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [Alias("SystemDbOnly", "NoUserDb")] [switch]$ExcludeAllUserDb, [Alias("UserDbOnly", "NoSystemDb")] [switch]$ExcludeAllSystemDb, [string[]]$Owner, [switch]$Encrypted, [ValidateSet('EmergencyMode', 'Normal', 'Offline', 'Recovering', 'Restoring', 'Standby', 'Suspect')] [string[]]$Status = @('EmergencyMode', 'Normal', 'Offline', 'Recovering', 'Restoring', 'Standby', 'Suspect'), [ValidateSet('ReadOnly', 'ReadWrite')] [string]$Access, [ValidateSet('Full', 'Simple', 'BulkLogged')] [string[]]$RecoveryModel = @('Full', 'Simple', 'BulkLogged'), [switch]$NoFullBackup, [datetime]$NoFullBackupSince, [switch]$NoLogBackup, [datetime]$NoLogBackupSince, [switch]$Silent, [switch]$IncludeLastUsed ) begin { if ($ExcludeAllUserDb -and $ExcludeAllSystemDb) { Stop-Function -Message "You cannot specify both ExcludeAllUserDb and ExcludeAllSystemDb" -Continue -Silent $Silent } } process { if (Test-FunctionInterrupt) { return } foreach ($instance in $SqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $instance" $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $sqlcredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } if (!$IncludeLastUsed) { $dblastused = $null } else { ##
