function Get-TPNMAllocation { <# .SYNOPSIS Retrieves allocation data from the database. .DESCRIPTION The Get-TPNMAllocation function retrieves allocation data from the database table 'Allocation'. It joins the Allocation table with ExtRange, Department, and Country tables to provide detailed information about each allocation. .PARAMETER CountryId The ID of the country. It should be a string with a maximum of 5 digits. .PARAMETER CountryName The name of the country. It should be a two-letter uppercase string (ISO 3166-1 alpha-2). .PARAMETER CountryCode The country code. It should be a string with a plus sign and a maximum of four digits (E.164). .PARAMETER DepartmentId The ID of the department. It should be a string with a maximum of 5 digits. .PARAMETER DepartmentName The name of the department. It should be a string with a maximum of 15 characters. .PARAMETER ExtRangeId The ID of the extension range. It should be a string with a maximum of 5 digits. .PARAMETER ExtRangeSpan The span of the extension range. It should be a string with a maximum of 15 characters. .PARAMETER AllocationId The ID of the allocation. It should be a string with a maximum of 5 digits. .PARAMETER AllocationExtension The extension of the allocation. It should be a string with a maximum of 15 digits. .PARAMETER AllocationState The state of the allocation. It should be a valid value from the TPNMAllocationState enum. .PARAMETER ResultSize The maximum number of results to return. It should be a positive integer or the string 'unlimited'. Default is 100. .PARAMETER Skip The number of results to skip. It should be zero or a positive integer. Default is 0. .EXAMPLE Get-TPNMAllocation -CountryId "123" -DepartmentName "Sales" This example retrieves allocation data for the country with ID "123" and the department named "Sales". .EXAMPLE Get-TPNMAllocation -CountryName "US" This example retrieves allocation data for the country with the name "US". .EXAMPLE Get-TPNMAllocation -CountryCode "+1" This example retrieves allocation data for the country with the code "+1". .EXAMPLE Get-TPNMAllocation -AllocationId "12345" This example retrieves the allocation with the ID "12345". .EXAMPLE Get-TPNMAllocation -ResultSize 10 -Skip 5 This example retrieves the fifth to fifteenth allocation data. .NOTES - This function requires the Invoke-TPNMSqlRequest and Optimize-TPNMSqlQueryFilter functions to be available. - The error action preference is set to 'Stop' to stop the function on any error. - The function uses verbose output to provide detailed information about the SQL query execution. .LINK https://github.com/jklotzsche-msft/TeamsPhoneNumberManagement #> [CmdletBinding(DefaultParameterSetName = 'Default')] param ( [ValidatePattern( '^\d{1,5}$', ErrorMessage = 'The id must be at maximum a 5 digit number.' )] [string] $CountryId, [ValidatePattern( '^[A-Z]{2}$', ErrorMessage = 'The Country Name must be a two-letter, uppercase string' )] [string] $CountryName, [ValidatePattern( '^\+\d{1,4}$', ErrorMessage = 'The country code must be a plus character followed by maximum three digits.' )] [string] $CountryCode, [ValidatePattern( '^\d{1,5}$', ErrorMessage = 'The id must be at maximum a 5 digit number.' )] [string] $DepartmentId, [ValidatePattern( '^\w{1,15}$', ErrorMessage = 'The department name must be at maximum a 15 character string.' )] [string] $DepartmentName, [ValidatePattern( '^\d{1,5}$', ErrorMessage = 'The id must be at maximum a 5 digit number.' )] [string] $ExtRangeId, [ValidatePattern( '^\d{1,15}$', ErrorMessage = 'This must be a 15 digit number.' )] [string] $ExtRangeSpan, [ValidatePattern( '^\d{1,5}$', ErrorMessage = 'The id must be at maximum a 5 digit number.' )] [string] $AllocationId, [ValidatePattern( '^\d{1,15}$', ErrorMessage = 'This must be a 15 digit number.' )] [string] $AllocationExtension, [TPNMAllocationState] $AllocationState, [ValidateScript({ if ($_ -is [int] -and $_ -ge 1) { $true } elseif ($_ -eq "unlimited") { $true } else { throw "ResultSize must be a positive integer value or the string 'unlimited'." } })] [Object] $ResultSize = 100, [ValidateScript({ if ($_ -is [int] -and $_ -ge 0) { $true } else { throw "Skip must be zero or a positive integer value." } })] [int] $Skip = 0 ) Begin { # Set the error action preference to stop and trap the error. $ErrorActionPreference = 'Stop' } Process { # Prepare resultset $resultSet = [System.Collections.Generic.List[pscustomobject]]::new() # Query the database for the allocation table $sqlQuery = @' SELECT Allocation.ID AS AllocationId, Allocation.Extension AS AllocationExtension, Allocation.State AS AllocationState, Allocation.CreatedOn AS AllocationCreatedOn, Allocation.Description AS AllocationDescription, ExtRange.ID AS ExtRangeId, ExtRange.Span AS ExtRangeSpan, ExtRange.SpanStart AS ExtRangeSpanStart, ExtRange.SpanEnd AS ExtRangeSpanEnd, Department.ID AS DepartmentId, Department.Name AS DepartmentName, Country.ID AS CountryId, Country.Code AS CountryCode, Country.Name AS CountryName FROM Allocation JOIN ExtRange ON Allocation.ExtRange = ExtRange.ID JOIN Department ON ExtRange.Department = Department.ID JOIN Country ON Department.Country = Country.ID; '@ # Add one or multiple where clauses to the SQL query, depending on the provided parameters $sqlQuery = Optimize-TPNMSqlQueryFilter -SqlQuery $sqlQuery -PassedParameter ($PSBoundParameters.GetEnumerator()) # Invoke the SQL query and add the result to the resultset Write-Verbose "Executing the following SQL query:`n$sqlQuery" Invoke-TPNMSqlRequest -SqlQuery $sqlQuery | ForEach-Object -Process { $resultSet.Add([PSCustomObject]$_) } Write-Verbose "Found $($resultSet.Count) entries." # If no allocation is found, stop the function and return a warning if ($resultSet.Count -eq 0) { Write-Warning -Message 'No allocation found.' return } # If needed, skip and limit the resultset # Then return the resultset, or if the function is used in an Azure Function App, push the resultset including the nextLink Push-TPNMResultSet -ResultSet $resultSet -ResultSize $ResultSize -Skip $Skip } } |
