List table indexes in Azure SQL Database

The query below lists table (and view) indexes.

Query

select schema_name(t.schema_id) + '.' + t.[name] as table_view,
    case when t.[type] = 'U' then 'Table'
        when t.[type] = 'V' then 'View'
    end as [object_type],
    i.index_id,
    case when i.is_primary_key = 1 then 'Primary key'
        when i.is_unique = 1 then 'Unique'
        else 'Not unique' end as [type],
    i.[name] as index_name,
    substring(column_names, 1, len(column_names)-1) as [columns],
    case when i.[type] = 1 then 'Clustered index'
        when i.[type] = 2 then 'Nonclustered unique index'
        when i.[type] = 3 then 'XML index'
        when i.[type] = 4 then 'Spatial index'
        when i.[type] = 5 then 'Clustered columnstore index'
        when i.[type] = 6 then 'Nonclustered columnstore index'
        when i.[type] = 7 then 'Nonclustered hash index'

Columns

  • table_view - name of table or view index is defined for
  • object_type - type of object that index is defined for:
    • Table
    • View
  • index_id - id of index (unique in table)
  • type
    • Primary key
    • Unique
    • Not unique
  • index_name - index name
  • columns - list of index columns separated with ","
  • index_type - index type:
    • Clustered index
    • Nonclustered unique index
    • XML index
    • Spatial index
    • Clustered columnstore index
    • Nonclustered columnstore index
    • Nonclustered hash index

Rows

  • One row: represents an index
  • Scope of rows: all indexes (unique and non-unique) in databases
  • Ordered by: schema, table name, index id
