Re-using Table Variable in Procedure

Hi,

I need to clear content of a table variable (which had data from database table TABLE1) an resue it later in my procedure to select data from different database table say TABLE 2. How do I do this. Trying to reuse gives error as the definitions of the 2 tables are different.

e.g.:

var1 = SELECT * FROM TABLE1;

-- Some logic where I use var1

var1 = SELECT * FROM TABLE2;

Above statement gives error as var1 is already binded to definition of TABLE1.

Thanks,

Anoop
