Util_TableSearch Mk2
By Jesse Roberge - YeshuaAgapao@Yahoo.com

Searches for tables who's names contain the search string.  Gives Aggregate Size, Rows, Index, and Column information as well.
LIKE wildcards are not automatic, which allows for easy 'begins with', 'ends with', and 'equal to' queries.
Improvements from Mk1: Added PartitionCount, IndexCount, ColumnCount, TotalMaxColumnLength, HasPrimaryKey, and HasClusteredIndex.
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.
Added searching of indexed (materialized; has a clustered index) views
Added searching of system tables

Update 2009-10-01:
Fixed system object searching (Catelog views do not have sys.dm_db_partition_stats entries)
Added optional output of non-materialized virtual table objects
Size and index output columns will be NULL for these.
All system catelog views and DMVs are non-materialized.

Required Input Parameters:
@TableName sysnameFilters tables.  Can use LIKE wildcards.  All tables if blank.

Optional Input Parameters:
@SchemaName sysname=''Filters schemas.  Can use LIKE wildcards.  All schemas if blank.
@VirtualTables TinyInt=0Search virutal tables (views, table-valued functions) - Size and Index output will be NULL for these
@UserOjbects TinyInt=1Search user objects
@SystemObjects TinyInt=0Search system objects

Usage
EXECUTE Util_TableSearch '%mpi%'
EXECUTE Util_TableSearch @SchemaName='dbo', @TableName='%order%'
