If you don't want all of your SQL statements to be echoed, but you only want to see the easily identifiable results of your script, do it this way:
set echo on
REM MyFirstTable
set echo off
delete from MyFirstTable;
set echo on
REM MySecondTable
set echo off
delete from MySecondTable;
The output from the above example will look something like this:
-REM MyFirstTable
13 rows deleted.
-REM MySecondTable
27 rows deleted.
