Restrictions

Typically, all columns of the DAX function results can be used as a restriction. Additional restrictions may also be allowed.

Return value

A table with the following columns:

Column name Data type Description
[ID] Integer The unique identifier of the column permission
[TablePermissionID] Integer The identifier of the table permission this column permission belongs to

Example

The following DAX query can be run in DAX query view:

EVALUATE
	INFO.COLUMNPERMISSIONS()

Example 2 - DAX query with joins

The following DAX query can be run in DAX query view:

EVALUATE
	VAR _ColumnPermissions =
		INFO.COLUMNPERMISSIONS()

	VAR _TablePermissions = 
		SELECTCOLUMNS(
			INFO.TABLEPERMISSIONS(),
			"TablePermissionID", [ID],
			"Table Permission Name", [Name],
			"RoleID", [RoleID],
			"TableID", [TableID]
		)

	VAR _Roles = 
		SELECTCOLUMNS(
			INFO.ROLES(),
			"RoleID", [ID],
			"Role Name", [Name]
		)

	VAR _Tables = 
		SELECTCOLUMNS(
			INFO.TABLES(),
			"TableID", [ID],
			"Table Name", [Name]
		)

	VAR _Columns = 
		SELECTCOLUMNS(
			INFO.COLUMNS(),
			"ColumnID", [ID],
			"Column Name", [ExplicitName]
		)

	VAR _CombinedWithTablePermissions =
		NATURALLEFTOUTERJOIN(
			_ColumnPermissions,
			_TablePermissions
		)

	VAR _CombinedWithRoles =
		NATURALLEFTOUTERJOIN(
			_CombinedWithTablePermissions,
			_Roles
		)

	VAR _CombinedWithTables =
		NATURALLEFTOUTERJOIN(
			_CombinedWithRoles,
			_Tables
		)

	VAR _CombinedWithColumns =
		NATURALLEFTOUTERJOIN(
			_CombinedWithTables,
			_Columns
		)

	RETURN
		SELECTCOLUMNS(
			_CombinedWithColumns,
			"Role Name", [Role Name],
			"Table Name", [Table Name],
			"Column Name", [Column Name],
			"Metadata Permission", [MetadataPermission],
			"Modified Time", [ModifiedTime]
		)
	ORDER BY [Role Name], [Table Name], [Column Name]
