Hi,
if you select “Create bulk insert statement” in the “Export data” window the file created by SQLyog 3.1 has a line containing just a “;” after every create table of empty tables.
When you try to load the .sql file with “Execute bath file” the import ends after the very first empty table! 😮
The problem exists only with the “Create bulk insert statement”, if you deselect it everything is OK 😉
By the way, there is another issue with the “Export data” window:
in SQLyog 3.1 it allows to export just ONE table (because after the first export the “export” button is disabled). Please leave it enabled because when you have to export 10 tables it's boring to open “Export data” 10 times.
Bye,
Daniele
