[sqlalchemy] [0.7.X] - Minor omission in documentation of Dialect-specific compilation rules
Hello all. My name is Ladislav Lenart and I am new to SQLAlchemy and this group. I've been reading SQLAlchemy documenation at: http://docs.sqlalchemy.org/en/rel_0_7/core/compiler.html#synopsis I think the section Dialect-specific compilation rules contains an error: * Both decorated compile functions use the same name 'visit_alter_column'. * The sentence immediately below the example talks about 'visit_alter_table'. I think the 2nd (postgresql specific) compile function should be called 'visit_alter_table'. Am I right or not?

Re: [sqlalchemy] fractional second percision- mysql
Yeah, I kind of suspected MySQLdb might have problems here. You need to file a bug report with the DBAPI's bug tracker: http://sourceforge.net/tracker/?group_id=22307atid=374932 I didn't see anything on the subject of fractional second support but I ended up getting the insert working by the format_TIME function in /MySQLdb/times.py to process microseconds: def format_TIMEDELTA(v): microseconds = v.microseconds seconds = float(v.seconds) % 60 minutes = int(v.seconds / 60) % 60 hours = int(v.seconds / 3600) % 24 return '%d %d:%d:%d.%d' % (v.days, hours, minutes, seconds, microseconds) Thank you for your help with the SQLalchemy side of things, redefining how the DDL is emitted for the type and whatnot. Hopefully we can see these changes in future releases of the 0.7 series. --James -- You received this message because you are subscribed to the Google Groups sqlalchemy group.

Hopefully we can see these changes in future releases of the 0.7 series. are you saying you patched mysqldb/times.py directly? yeah, MySQLdb would need to implement this change properly for the SQLAlchemy side of things to be of any use. We can't just tell our users to patch their MySQLdb clients. harmless enough for us to look for the microseconds portion on our end, anyway. -- You received this message because you are subscribed to the Google Groups sqlalchemy group.
