Reports information about the indexes on a table or view.

Transact-SQL syntax conventions

Syntax

sp_helpindex [ @objname = ] N'objname'
[ ; ]

Arguments

[ @objname = ] N'objname'

The qualified or nonqualified name of a user-defined table or view. @objname is nvarchar(776), with no default. Quotation marks are required only if a qualified table or view name is specified. If a fully qualified name, including a database name, is provided, the database name must be the name of the current database.

Return code values

0 (success) or 1 (failure).

Result set

Column name Data type Description
index_name sysname Index name.
index_description varchar(210) Index description, including the filegroup in which it's located.
index_keys nvarchar(2078) Table or view columns upon which the index is built.

A descending indexed column is listed in the result set with a minus sign (-) following its name; an ascending indexed column, the default, is listed by its name alone.

Remarks

If indexes are set by using the NORECOMPUTE option of UPDATE STATISTICS, that information is included in the index_description column.

sp_helpindex exposes only orderable index columns; therefore, it doesn't expose information about XML indexes or spatial indexes.

Permissions

Requires membership in the public role.
