Util_TablesWithoutPKOrCL
By Jesse Roberge - YeshuaAgapao@Yahoo.com

Lists Schema/Object of tables that are missing a Primary Key, missing a Clustered Index, or the clustered index is not declared as unique,
along with aggregate data for size, rows, indexes, and columns.
Has the same output as Util_TableSearch Mk2 but only outputs tables that are missing a Primary Key or Clustered Index (or both) rather than performing a name pattern search.
Requires the VIEW DATABASE STATE database permission.

Update 2009-01-14:
Fixed Rows Output - Was being erroneously multiplied by (1+#NonClusteredIndexes)
SUM(Rows) Should be SUM(CASE WHEN index_id BETWEEN 0 AND 1 THEN row_count ELSE 0 END)

Update 2009-09-21:
Added HasUniqueIndex, ClusteredIndexIsUnique, PrimaryKeyIsClustered, and NonPKUniqueIndexCount.

Required Input Parameters
none

Optional Input Parameters
none

Usage
