I have a data source that is a folder filled with daily txt files.  Everyday I want to be able to automatically read yesterday's file.  In Report Services if I use the following code I am able to see the contents of a file.  
SELECT        *
FROM            12272012.txt

In SSMS if I use this code...
SELECT replace(convert(varchar, DATEADD(d, -1,getdate()), 101), '/', '') + '.txt' as ErrLog

It produces the file name I need (Ex: 12272012.txt) but it doesn't work in the FROM statement of SSRS.   Please help me with how I need to change this to make it work in SSRS?
SELECT *
FROM replace(convert(varchar, DATEADD(d, -1,getdate()), 101), '/', '') + '.txt'

try using a stored procedure instead

 CREATE PROCEDURE myDynamic

AS

DECLARE @SQL NVARCHAR(4000)
DECLARE @table NVARCHAR(100)
SET @table =replace(convert(varchar, DATEADD(d, -1,getdate()), 101), '/', '') + '.txt'

SET @SQL='SELECT * FROM '+@Table

EXEC(@SQL)

Thank you for your help but if I do that I'm not sure how to access the sp.  Currently the data I need to access is a text file so my DataSource is an ODBC connection.  I don't know how to use my ODBC Data source connection and then connect to the sp.  Should I be doing this an entirely different way?

One thing you may want to look at; is made your txt files into XML (layout) file.
since SSRS are just readable XML files.

Thank you for your input!  Is there a place I can go to read more about how to do this?  Or can you provide me with more details?  I would still need to be able to automatically update the txt file to an xml file and I don't know how to do that.

you  will need to most likely do it in VB or C# coding. Their is a standard import file from the framework that has all the info to make and read a XML file. It  would be too much detail work to post here. you may want to get a code book or look online to "How to create and read XML files".
