How to make 'symfony doctrine:build-sql' task generate 'DROP' statments?

问题

Is there a way to make symfony doctrine:build-sql task generate DROP statments before CREATE TABLE ones as it symfony propel:build-sql does ? ?

回答1:

There is no such possibility, but you can run the doctrine:drop-db task before inserting the the SQL. A regular way with doctrine is:

> symfony doctrine:build-sql
> symfony doctrine:drop-db
> symfony doctrine:insert-sql
