Hi, Is it possible just using schema api abstraction to share a sequence across several tables? Will it be possible in D7? BTW is there a place to see what are the current feature of D7 DB abstraction layer? I'm going to skip porting to D6 some stuff directly to D7 and I'll have to start with some advance since the stuff is huge. thanks -- Ivan Sergio Borgonovo http://www.webthatworks.it
