Function Export-DbaScript { <# .SYNOPSIS Exports scripts from SQL Management Objects (SMO) .DESCRIPTION Exports scripts from SQL Management Objects .PARAMETER InputObject A SQL Managment Object such as the one returned from Get-DbaLogin .PARAMETER Path The output filename and location. If no path is specified, one will be created. If the file already exists, the output will be appended. .PARAMETER Encoding Specifies the file encoding. The default is UTF8. Valid values are: -- ASCII: Uses the encoding for the ASCII (7-bit) character set. -- BigEndianUnicode: Encodes in UTF-16 format using the big-endian byte order. -- Byte: Encodes a set of characters into a sequence of bytes. -- String: Uses the encoding type for a string. -- Unicode: Encodes in UTF-16 format using the little-endian byte order. -- UTF7: Encodes in UTF-7 format. -- UTF8: Encodes in UTF-8 format. -- Unknown: The encoding type is unknown or invalid. The data can be treated as binary. .PARAMETER Passthru Output script to console .PARAMETER ScriptingOptionObject An SMO Scripting Object that can be used to customize the output - see New-DbaScriptingOption .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: Migration, Backup, Export 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/Export-DbaScript .EXAMPLE Get-DbaAgentJob -SqlInstance sql2016 | Export-DbaScript Exports all jobs on the SQL Server sql2016 instance using a trusted connection - automatically determines filename as .\sql2016-Job-Export-date.sql .EXAMPLE Get-DbaAgentJob -SqlInstance sql2016 -Jobs syspolicy_purge_history, 'Hourly Log Backups' -SqlCredential (Get-Credetnial sqladmin) | Export-DbaScript -Path C:\temp\export.sql Exports only syspolicy_purge_history and 'Hourly Log Backups' to C:temp\export.sql and uses the SQL login "sqladmin" to login to sql2016 .EXAMPLE Get-DbaAgentJob -SqlInstance sql2014 | Export-DbaJob -Passthru | ForEach-Object { $_.Replace('sql2014','sql2016') } | Set-Content -Path C:\temp\export.sql Exports jobs and replaces all instances of the servername "sql2014" with "sql2016" then writes to C:\temp\export.sql .EXAMPLE $options = New-DbaScriptingOption $options.ScriptDrops = $false $options.WithDependencies = $true Get-DbaAgentJob -SqlInstance sql2016 | Export-DbaScript -ScriptingOptionObject $options Exports Agent Jobs with the Scripting Options ScriptDrops set to $false and WithDependencies set to true. #> [CmdletBinding(SupportsShouldProcess = $true)] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [object[]]$InputObject, [Microsoft.SqlServer.Management.Smo.ScriptingOptions]$ScriptingOptionObject, [string]$Path, [ValidateSet('ASCII', 'BigEndianUnicode', 'Byte', 'String', 'Unicode', 'UTF7', 'UTF8', 'Unknown')] [string]$Encoding = 'UTF8', [switch]$Passthru, [switch]$Silent ) begin { $executinguser = [Security.Principal.WindowsIdentity]::GetCurrent().Name $commandname = $MyInvocation.MyCommand.Name $timenow = (Get-Date -uformat "%m%d%Y%H%M%S") $prefixarray = @() } process { foreach ($object in $inputobject) { $typename = $object.GetType().ToString() if ($typename.StartsWith('Microsoft.SqlServer.')) { $shortype = $typename.Split(".")[-1] } else { Stop-Function -Message "InputObject is of type $typename which is not a SQL Management Object.
