SQL 2012 :: Searching For Table Names In SSRS Reports In SharePoint

I am trying to query the SharePoint database to get a list of how many times a table name is being used in our SSRS reports.Here is my current query:

DECLARE @TEXTTOSEARCH AS VARCHAR(200)
SET @TEXTTOSEARCH = 'tablenamehere'
;WITH XMLNAMESPACES
(DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition',
'http://schemas.microsoft.com/SQLServer/reporting/reportdesigner' AS rd)

[code]...

This works for some tables since the names are unique and I can just do a search for that. However, some of the table names are simple and can also be used as aliases.if there was some way to get the list of table names easier.
