Is it possible to T-SQL "merge" a text file into a SQL table?

Hi All,

I have a text file that I want to "merge" (i.e., insert, update, and delete) directly into a SQL 2012 table.  Can this be done with SSIS?  I assume not, and that I'll need to load the text file into a staging table before performing a T-SQL merge.

Thanks,
Eric B.
