Hi AlabamaPamela,
Unfortunately, there is no way to void out the entire batch. As Matt mentioned you would need to void out each individually. In regards to your second question about changing the void status in SQL. As Matt had also mentioned it would not back out the transactions that were posted to the Bank Rec tables and the General Ledger.
The supported method is to void from the front end of Dynamics GP as Matt mentioned.
