Function Get-AtwsAttachmentInfo
{


<#
.SYNOPSIS
This function get one or more AttachmentInfo 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:
 
ParentType
  
 
Type
  
 
Publish
  
 
Entities that have fields that refer to the base entity of this CmdLet:
 
 
.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.AttachmentInfo[]]. This function outputs the Autotask.AttachmentInfo that was returned by the API.
.EXAMPLE
Get-AtwsAttachmentInfo -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsAttachmentInfo -AttachmentInfoName SomeName
Returns the object with AttachmentInfoName 'SomeName', if any.
 .EXAMPLE
Get-AtwsAttachmentInfo -AttachmentInfoName 'Some Name'
Returns the object with AttachmentInfoName 'Some Name', if any.
 .EXAMPLE
Get-AtwsAttachmentInfo -AttachmentInfoName 'Some Name' -NotEquals AttachmentInfoName
Returns any objects with a AttachmentInfoName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsAttachmentInfo -AttachmentInfoName SomeName* -Like AttachmentInfoName
Returns any object with a AttachmentInfoName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsAttachmentInfo -AttachmentInfoName SomeName* -NotLike AttachmentInfoName
Returns any object with a AttachmentInfoName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsAttachmentInfo -ParentType <PickList Label>
Returns any AttachmentInfos with property ParentType equal to the <PickList Label>. '-PickList' is any parameter on .
 .EXAMPLE
Get-AtwsAttachmentInfo -ParentType <PickList Label> -NotEquals ParentType
Returns any AttachmentInfos with property ParentType NOT equal to the <PickList Label>.
 .EXAMPLE
Get-AtwsAttachmentInfo -ParentType <PickList Label1>, <PickList Label2>
Returns any AttachmentInfos with property ParentType equal to EITHER <PickList Label1> OR <PickList Label2>.
 .EXAMPLE
Get-AtwsAttachmentInfo -ParentType <PickList Label1>, <PickList Label2> -NotEquals ParentType
Returns any AttachmentInfos with property ParentType NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
 .EXAMPLE
Get-AtwsAttachmentInfo -Id 1234 -AttachmentInfoName SomeName* -ParentType <PickList Label1>, <PickList Label2> -Like AttachmentInfoName -NotEquals ParentType -GreaterThan Id
An example of a more complex query. This command returns any AttachmentInfos with Id GREATER THAN 1234, a AttachmentInfoName that matches the simple pattern SomeName* AND that has a ParentType that is NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
