#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function New-DbaAgentSchedule { <# .SYNOPSIS New-DbaAgentSchedule creates a new schedule in the msdb database. .DESCRIPTION New-DbaAgentSchedule will help create a new schedule for a job. If the job parameter is not supplied the schedule will not be attached to a job. .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. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Job The name of the job that has the schedule. .PARAMETER Schedule The name of the schedule. .PARAMETER Disabled Set the schedule to disabled. Default is enabled .PARAMETER FrequencyType A value indicating when a job is to be executed. Allowed values: Once, Daily, Weekly, Monthly, MonthlyRelative, AgentStart or IdleComputer If force is used the default will be "Once". .PARAMETER FrequencyInterval The days that a job is executed Allowed values: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Weekdays, Weekend or EveryDay. The other allowed values are the numbers 1 to 31 for each day of the month. If "Weekdays", "Weekend" or "EveryDay" is used it over writes any other value that has been passed before. If force is used the default will be 1. .PARAMETER FrequencySubdayType Specifies the units for the subday FrequencyInterval. Allowed values: Time, Seconds, Minutes, or Hours .PARAMETER FrequencySubdayInterval The number of subday type periods to occur between each execution of a job. .PARAMETER FrequencyRelativeInterval A job's occurrence of FrequencyInterval in each month, if FrequencyInterval is 32 (monthlyrelative). Allowed values: First, Second, Third, Fourth or Last .PARAMETER FrequencyRecurrenceFactor The number of weeks or months between the scheduled execution of a job. FrequencyRecurrenceFactor is used only if FrequencyType is "Weekly", "Monthly" or "MonthlyRelative". .PARAMETER StartDate The date on which execution of a job can begin. If force is used the start date will be the current day .PARAMETER EndDate The date on which execution of a job can stop. If force is used the end date will be '9999-12-31' .PARAMETER StartTime The time on any day to begin execution of a job. Format HHMMSS / 24 hour clock. Example: '010000' for 01:00:00 AM. Example: '140000' for 02:00:00 PM. If force is used the start time will be '00:00:00' .PARAMETER EndTime The time on any day to end execution of a job. Format HHMMSS / 24 hour clock. Example: '010000' for 01:00:00 AM. Example: '140000' for 02:00:00 PM. If force is used the start time will be '23:59:59' .PARAMETER Owner The name of the server principal that owns the schedule. If no value is given the schedule is owned by the creator. .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 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. .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, Job, JobStep 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/New-DbaAgentSchedule .EXAMPLE PS C:\> New-DbaAgentSchedule -SqlInstance localhost\SQL2016 -Schedule daily -FrequencyType Daily -FrequencyInterval Everyday -Force Creates a schedule with a daily frequency every day.
