SSIS

Hi
I need to use variables with my sql script files using SSIS
let's say, I have a file with following sql statements

insert into     neu_10_1_2013_rv4.dbo.edi_ack_code values (1, 'TR', 'Transaction Rejected');
insert into     neu_10_1_2013_rv4.dbo.edi_ack_code values (2, 'TA', 'Transaction Accepted');
insert into     neu_10_1_2013_rv4.dbo.edi_ack_code values (3, 'TE', 'Transaction Accepted W/ Errors');

I need to change database name for different databases
like from neu_10_1_2013_rv4 to TARGET

Or please suggest other solution for the same.
