View B dependency on table A Issues arising from modifying A

[liyuan116]

In previous version 0.12.2, we created a view B dependency on table A and then deleted table A by changing the primary key of table A or deleting a field of table A. It is good to create a temporary table a_temp and write data from table A. Finally, it is good to delete table A and rename a_temp to Table A.

However, 0.13.3 release is not ok the error is View B depends on Table A not found What's going on？ What's the right thing to do？

thanks～
