Util_ColumnSearch
By Jesse Roberge - YeshuaAgapao@Yahoo.com
Update - Fixed existance check for drop

Searches for columns with names containing @Colname that belong to tables with names containing @TableName (optional) or schemas with names containing @SchemaName (optional). Gives size and rowcount for tables.
LIKE wildcards are not automatic, which allows for easy 'begins with', 'ends with', and 'equal to' queries.
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:
Fixed column_id sorting, now sorts correctly as an int rather than a (converted) string
Added searching of system tables

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

Required Input Parameters
@ColumnName sysnameFilters columns.  Can use LIKE wildcards.

Optional Input Parameters
@SchemaName sysname=''Filters schemas.  Can use LIKE wildcards.  All schemas if blank.
@TableName sysname=''Filters tables.  Can use LIKE wildcards.  All tables if blank.
@VirtualTables TinyInt=0Search virutal tables (views, table-valued functions) - Size output will be NULL for these
@UserOjbects TinyInt=1Search user objects
@SystemObjects TinyInt=0Search system objects
@Sort TinyInt=11=sort by SchemaName, TableName, ColumnID; 2=sort by SchemaName, TableName, ColumnName

Usage
EXECUTE Util_ColumnSearch '%price%'
EXECUTE Util_ColumnSearch @SchemaName='dbo', @Tablename='cart%', @Columnname='%price%'
