function Get-DbaDbccHelp { <# .SYNOPSIS Execution of Database Console Command DBCC HELP .DESCRIPTION Returns the results of DBCC HELP Read more: - https://docs.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-help-transact-sql .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Statement Is the name of the DBCC command for which to receive syntax information. Provide only the part of the DBCC command that follows DBCC, for example, CHECKDB instead of DBCC CHECKDB. .PARAMETER IncludeUndocumented Allows getting help for undocumented DBCC commands. Requires Traceflag 2588 This only works for SQL Server 2005 or Higher .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: DBCC Author: Patrick Flynn (@sqllensman) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDbccUserOptions .EXAMPLE PS C:\> Get-DbaDbccHelp -SqlInstance SQLInstance -Statement FREESYSTEMCACHE -Verbose | Format-List Runs the command DBCC HELP(FREESYSTEMCACHE) WITH NO_INFOMSGS against the SQL Server instance SQLInstance .EXAMPLE PS C:\> Get-DbaDbccHelp -SqlInstance LensmanSB -Statement WritePage -IncludeUndocumented | Format-List Sets TraeFlag 2588 on for session and then runs the command DBCC HELP(WritePage) WITH NO_INFOMSGS against the SQL Server instance SQLInstance #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string]$Statement, [switch]$IncludeUndocumented, [switch]$EnableException ) begin { if (Test-Bound -Not -ParameterName Statement) { Stop-Function -Message "You must specify a value for Statement" return } $stringBuilder = New-Object System.Text.StringBuilder if (Test-Bound -ParameterName IncludeUndocumented) { $null = $stringBuilder.Append("DBCC TRACEON (2588) WITH NO_INFOMSGS;") } Write-Message -Message "Get Help Information for $Statement" -Level Verbose $null = $stringBuilder.Append("DBCC HELP($Statement) WITH NO_INFOMSGS;") } process { foreach ($instance in $SqlInstance) { Write-Message -Message "Attempting Connection to $instance" -Level Verbose try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 9 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } try { $query = $StringBuilder.ToString() Write-Message -Message "Query to run: $query" -Level Verbose $results = $server | Invoke-DbaQuery -Query $query -MessagesToOutput } catch { Stop-Function -Message "Failure" -ErrorRecord $_ -Target $server -Continue } [PSCustomObject]@{ Operation = $Statement Cmd = "DBCC HELP($Statement)" Output = $results } } } } |
