Gets all columns matching the supplied Filter.

Syntax

Get-ClassificationColumnForFilter [[-Filter] <Filter>] [[-MaxNumberOfResults] <int>] [[-StartResultNumber] <int>] [<CommonParameters>]

Description

Gets all columns matching the supplied Filter.

Available Filter properties: Instances [StringPropertyFilter] Databases [StringPropertyFilter] TablesWithSchemas [StringPropertyFilter] Columns [StringPropertyFilter] Tags [TagsFilter] PredictedInformationTypes [StringPropertyFilter] ColumnDataTypes [StringPropertyFilter] EmptyTablesFilter [One of ('Require', 'Include', 'Exclude')] PrimaryKeyFilter [One of ('Require', 'Include', 'Exclude')] IdentityConstraintFilter [One of ('Require', 'Include', 'Exclude')] CompositeKeyFilter [One of ('Require', 'Include', 'Exclude')] ForeignKeyFilter [One of ('Require', 'Include', 'Exclude')] WithNoTags [Boolean] WithTagsApplied [Boolean]

Where a StringPropertyFilter has the options: Include [string[]] IncludePartial [string[]] Exclude [string[]] ExcludePartial [string[]]

And TagsFilter has: Include [hashtable e.g. @{ "Information Classification" = @("Confidential") }] Exclude [hashtable e.g. @{ "Information Classification" = @("Confidential") }]

And where: 'Include' = Do not apply any restrictions based on this filter (e.g. Include all tables including empty tables) 'Exclude' = Exclude items matching this filter (e.g. Don't include empty tables) 'Require' = Restrict to items that match this filter (e.g. only include empty tables)

Parameters

Examples

-------------------------- EXAMPLE 1 --------------------------

$filter = New-ClassificationColumnFilter
$filter.Instances.Include = @('sqlserver\2016')
$filter.Databases.Include = @('WorldWideImporters')
Get-ClassificationColumnForFilter -Filter $filter

Fetches all columns from instance "sqlserver\sql2016" database "WideWorldImporters".

-------------------------- EXAMPLE 2 --------------------------

$filter = New-ClassificationColumnFilter
$filter.Instances.Include = @('sqlserver\2016', 'sqlserver\staging')
$filter.Databases.IncludePartial = @('world')
Get-ClassificationColumnForFilter -Filter $filter

Fetches all columns from all databases containing the term "world" (e.g. WideWorldImporters) on instances "sqlserver\prod" and "sqlserver\staging".

-------------------------- EXAMPLE 3 --------------------------

$filter = New-ClassificationColumnFilter
$filter.Instances.Include = @('sqlserver\test')
$filter.Columns.ExcludePartial=@('%ID')
$filter.EmptyTablesFilter = 'Exclude'
$filter.WithNoTags = $true
Get-ClassificationColumnForFilter -Filter $filter

Fetches all columns from instance "sqlserver\test" that don't have a name ending with 'ID' that are not in empty tables but have no columns applied.

-------------------------- EXAMPLE 4 --------------------------

$filter = New-ClassificationColumnFilter
$filter.WithNoTags = $true
Get-ClassificationColumnForFilter -Filter $filter  -StartResultNumber 100 -MaxNumberOfResults 25

Fetches up to 25 columns contained within empty tables from all registered databases and instances, ignoring the first 100 matched columns.
