Function Get-AtwsInstalledProductNote
{


<#
.SYNOPSIS
This function get one or more InstalledProductNote through the Autotask Web Services API.
.DESCRIPTION
This function creates a query based on any parameters you give and returns any resulting objects from the Autotask Web Services Api. By default the function returns any objects with properties that are Equal (-eq) to the value of the parameter. To give you more flexibility you can modify the operator by using -NotEquals [ParameterName[]], -LessThan [ParameterName[]] and so on.

Possible operators for all parameters are:
 -NotEquals
 -GreaterThan
 -GreaterThanOrEqual
 -LessThan
 -LessThanOrEquals

Additional operators for [string] parameters are:
 -Like (supports * or % as wildcards)
 -NotLike
 -BeginsWith
 -EndsWith
 -Contains

Properties with picklists are:
NoteType

Entities that have fields that refer to the base entity of this CmdLet:


.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.InstalledProductNote[]]. This function outputs the Autotask.InstalledProductNote that was returned by the API.
.EXAMPLE
Get-AtwsInstalledProductNote -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsInstalledProductNote -InstalledProductNoteName SomeName
Returns the object with InstalledProductNoteName 'SomeName', if any.
 .EXAMPLE
Get-AtwsInstalledProductNote -InstalledProductNoteName 'Some Name'
Returns the object with InstalledProductNoteName 'Some Name', if any.
 .EXAMPLE
Get-AtwsInstalledProductNote -InstalledProductNoteName 'Some Name' -NotEquals InstalledProductNoteName
Returns any objects with a InstalledProductNoteName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsInstalledProductNote -InstalledProductNoteName SomeName* -Like InstalledProductNoteName
Returns any object with a InstalledProductNoteName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsInstalledProductNote -InstalledProductNoteName SomeName* -NotLike InstalledProductNoteName
Returns any object with a InstalledProductNoteName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsInstalledProductNote -NoteType <PickList Label>
Returns any InstalledProductNotes with property NoteType equal to the <PickList Label>. '-PickList' is any parameter on .
 .EXAMPLE
Get-AtwsInstalledProductNote -NoteType <PickList Label> -NotEquals NoteType
Returns any InstalledProductNotes with property NoteType NOT equal to the <PickList Label>.
 .EXAMPLE
Get-AtwsInstalledProductNote -NoteType <PickList Label1>, <PickList Label2>
Returns any InstalledProductNotes with property NoteType equal to EITHER <PickList Label1> OR <PickList Label2>.
 .EXAMPLE
Get-AtwsInstalledProductNote -NoteType <PickList Label1>, <PickList Label2> -NotEquals NoteType
Returns any InstalledProductNotes with property NoteType NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
 .EXAMPLE
Get-AtwsInstalledProductNote -Id 1234 -InstalledProductNoteName SomeName* -NoteType <PickList Label1>, <PickList Label2> -Like InstalledProductNoteName -NotEquals NoteType -GreaterThan Id
An example of a more complex query. This command returns any InstalledProductNotes with Id GREATER THAN 1234, a InstalledProductNoteName that matches the simple pattern SomeName* AND that has a NoteType that is NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
