I understand the copy and paste option.
I am generating SQL scripts from elsewhere, say to rebuild the database and to import fixed data from different sources.
I also want to write ad-hoc sql. So within MySql tool I would like to have the following lines
run script to re-build database;
run script to import data;
hand written sql statement/s here;
run script to export data;
Then I want to highlight the ones I want and ctrl F9 to run as usual.
