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

Lists details for all indexes on one or more tables / schemas, including row count and size.
If you want data types and other column information and one row per index instead of one row per member column,
  then use Util_ListIndexes_Columns instead.

Update 2009-01-14:
	Added IndexDepth and FillFactor output columns
	Added @Delimiter parameter for the column listing output (Defaults to ,) for accomodating export to delimited files.
	Removed duplicate output of 'is_unique'

Required Input Parameters
	none

Optional Input Parameters
	@SchemaName sysname=''		Filters to a single schema.  Can use LIKE wildcards.  All schemas if blank.  Accepts LIKE Wildcards.
	@TableName sysname=''		Filters to a single table.  Can use LIKE wildcards.  All tables if blank.  Accepts LIKE Wildcards.
	@Delimiter VarChar(1)=','	Delimiter for the horizontal delimited seek and include column listings. For accomdating csv export.

Usage
	EXECUTE Util_ListIndexes 'dbo', 'Cart'
