function Get-DbaAgentSchedule { <# .SYNOPSIS Returns all SQL Agent Shared Schedules on a SQL Server Agent. .DESCRIPTION This function returns SQL Agent Shared Schedules. .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 Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Schedule Parameter to filter the schedules returned .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: Agent, Schedule Author: Chris McKeown (@devopsfu), http://www.devopsfu.com Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaAgentSchedule .EXAMPLE Get-DbaAgentSchedule -SqlInstance localhost Returns all SQL Agent Shared Schedules on the local default SQL Server instance .EXAMPLE Get-DbaAgentSchedule -SqlInstance localhost, sql2016 Returns all SQL Agent Shared Schedules for the local and sql2016 SQL Server instances #> [CmdletBinding()] param ( [parameter(Position = 0, Mandatory = $true, ValueFromPipeline = $True)] [Alias("ServerInstance", "Instance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [Alias("Schedules")] [object[]]$Schedule, [PSCredential]$SqlCredential, [Alias('Silent')] [switch]$EnableException ) begin { function Get-ScheduleDescription { param ( [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [object]$Schedule ) # Get the culture to make sure the right date and time format is displayed $datetimeFormat = (Get-culture).DateTimeFormat # Set the intial description $description = "" # Get the date and time values $startDate = Get-Date $Schedule.ActiveStartDate -format $datetimeFormat.ShortDatePattern $startTime = Get-Date ($Schedule.ActiveStartTimeOfDay.ToString()) -format $datetimeFormat.LongTimePattern $endDate = Get-Date $Schedule.ActiveEndDate -format $datetimeFormat.ShortDatePattern $endTime = Get-Date ($Schedule.ActiveEndTimeOfDay.ToString()) -format $datetimeFormat.LongTimePattern # Start setting the description based on the frequency type switch ($schedule.FrequencyTypes) { {($_ -eq 1) -or ($_ -eq "Once")} { $description += "Occurs on $startDate at $startTime" } {($_ -in 4, 8, 16, 32) -or ($_ -in "Daily", "Weekly", "Monthly")} { $description += "Occurs every "} {($_ -eq 64) -or ($_ -eq "AutoStart")} {$description += "Start automatically when SQL Server Agent starts "} {($_ -eq 128) -or ($_ -eq "OnIdle")} {$description += "Start whenever the CPUs become idle"} } # Check the frequency types for daily or weekly i.e. switch ($schedule.FrequencyTypes) { # Daily {$_ -in 4, "Daily"} { if ($Schedule.FrequencyInterval -eq 1) { $description += "day " } elseif ($Schedule.FrequencyInterval -gt 1) { $description += "$($Schedule.FrequencyInterval) day(s) " } } # Weekly {$_ -in 8, "Weekly"} { # Check if it's for one or more weeks if ($Schedule.FrequencyRecurrenceFactor -eq 1) { $description += "week on " } elseif ($Schedule.FrequencyRecurrenceFactor -gt 1) { $description += "$($Schedule.FrequencyRecurrenceFactor) week(s) on " } # Save the interval for the loop $frequencyInterval = $Schedule.FrequencyInterval # Create the array to hold the days $days = ($false, $false, $false, $false, $false, $false, $false) # Loop through the days while ($frequencyInterval -gt 0) { switch ($FrequenctInterval) { {($frequencyInterval -
