function Remove-DbaAgentSchedule { <# .SYNOPSIS Remove-DbaAgentJobSchedule removes a job schedule. .DESCRIPTION Remove-DbaAgentJobSchedule removes a job in the SQL Server Agent. .PARAMETER SqlInstance The target SQL Server instance or instances. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER 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. .PARAMETER Schedule The name of the job schedule. .PARAMETER InputObject A collection of schedule (such as returned by Get-DbaAgentSchedule), to be removed. .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 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. .PARAMETER Force The force parameter will ignore some errors in the parameters and assume defaults. It will also remove the any present schedules with the same name for the specific job. .NOTES Tags: Agent, Job, Schedule Author: Sander Stad (@sqlstad), sqlstad.nl Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Remove-DbaAgentJobSchedule .EXAMPLE PS C:\> Remove-DbaAgentSchedule -SqlInstance sql1 -Schedule weekly Remove the schedule weekly .EXAMPLE PS C:\> Remove-DbaAgentSchedule -SqlInstance sql1 -Schedule weekly -Force Remove the schedule weekly from the job even if the schedule is being used by another job. .EXAMPLE PS C:\> Remove-DbaAgentSchedule -SqlInstance sql1 -Schedule daily, weekly Remove multiple schedule .EXAMPLE PS C:\> Remove-DbaAgentSchedule -SqlInstance sql1, sql2, sql3 -Schedule daily, weekly Remove the schedule on multiple servers for multiple schedules .EXAMPLE sql1, sql2, sql3 | Remove-DbaAgentSchedule -Schedule daily, weekly Remove the schedule on multiple servers using pipe line .EXAMPLE Get-DbaAgentSchedule -SqlInstance sql1 -Schedule sched1, sched2, sched3 | Remove-DbaAgentSchedule Remove the schedules using a pipeline #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = "Low")] param ( [parameter(Mandatory, ValueFromPipeline, ParameterSetName = "instance")] [DbaInstanceParameter[]]$SqlInstance, [System.Management.Automation.PSCredential]$SqlCredential, [Parameter(Mandatory, ParameterSetName = "instance")] [ValidateNotNullOrEmpty()] [Alias("Schedules")] [object[]]$Schedule, [Parameter(ValueFromPipeline, Mandatory, ParameterSetName = "schedules")] [Microsoft.SqlServer.Management.Smo.Agent.ScheduleBase[]]$InputObject, [switch]$EnableException, [switch]$Force ) begin { if ($Force) {$ConfirmPreference = 'none'} } process { foreach ($instance in $sqlinstance) { # Try connecting to the instance try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $InputObject += $server.JobServer.SharedSchedules if ($Schedule) { $InputObject = $InputObject | Where-Object Name -in $Schedule } } # foreach object instance foreach ($currentschedule in $InputObject) { $server = $currentschedule.Parent.Parent if (-not $server) { $server = $currentschedule.Parent } $server.JobServer.SharedSchedules.Refresh() $schedulename = $currentschedule.Name $jobCount = $server.JobServer.SharedSchedules[$currentschedule].JobCount # Check if the schedule is shared among other jobs if ($jobCount -ge 1 -and -not $Force) { Stop-Function -Message "The schedule $schedulename is shared connected to one or more jobs.
