Parameterized table name in BODS

How can we parameterized table name in SQL transformation of BODS?

The requirement is to fetch and save data to a file/table from multiple tables where the table name is coming from a global variable and value of this variable will change every time as the loop increments.

Select * from [$Table_Name]

I am able to fetch table name in the global parameter "$Table_Name" but not able to extract the data from this table.

Any thoughts??
