Transact-SQL Syntax Conventions
- [ @objname =] 'object_name'
-
Specifies the table on which to provide statistics information. object_name is nvarchar(520) and cannot be null. A one- or two-part name can be specified.
- [ @results =] 'value'
-
Specifies the extent of information to provide. Valid entries are ALL and STATS. ALL lists statistics for all indexes and also columns that have statistics created on them; STATS only lists statistics not associated with an index. value is nvarchar(5) with a default of STATS.
Use DBCC SHOW_STATISTICS to display detailed statistics information about any particular index or statistics. For more information, see DBCC SHOW_STATISTICS (Transact-SQL) and sp_helpindex (Transact-SQL).
The following example creates single-column statistics for all eligible columns for all user tables in the AdventureWorks database by executing sp_createstats. Then, sp_helpstats is run to find the resultant statistics created on the Customer table.
USE AdventureWorks; GO EXEC sp_createstats; GO EXEC sp_helpstats @objname = 'Sales.Customer', @results = 'ALL'
Here is the result set.
