function Remove-DbaAgentSchedule { <# .SYNOPSIS Remove-DbaAgentJobSchedule removes a job schedule. .DESCRIPTION Remove-DbaAgentJobSchedule removes a a job in the SQL Server Agent. .PARAMETER SqlInstance SQL Server instance. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Schedule The name of the job schedule. .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 Author: Sander Stad (@sqlstad, sqlstad.nl) Tags: Agent, Job, Job Step, Schedule 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/Remove-DbaAgentJobSchedule .EXAMPLE Remove-DbaAgentSchedule -SqlInstance sql1 -Schedule weekly Remove the schedule weekly .EXAMPLE 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 Remove-DbaAgentSchedule -SqlInstance sql1 -Schedule daily, weekly Remove multiple schedule .EXAMPLE 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 #> [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = "Low")] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [object[]]$SqlInstance, [System.Management.Automation.PSCredential] $SqlCredential, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [object[]]$Schedule, [switch][Alias('Silent')]$EnableException, [switch]$Force ) process { foreach ($instance in $sqlinstance) { # Try connecting to the instance Write-Message -Message "Attempting to connect to $instance" -Level Verbose try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Could not connect to Sql Server instance $instance" -Target $instance -InnerErrorRecord $_ -Continue } foreach ($s in $Schedule) { if ($Server.JobServer.SharedSchedules.Name -contains $s) { # Get job count $jobCount = $Server.JobServer.SharedSchedules[$s].JobCount # Check if the schedule is shared among other jobs if ($jobCount -ge 1 -and -not $Force) { Stop-Function -Message "The schedule $s is shared connected to one or more jobs.
