you use a ConnectionProxy for this (will be the "execute" event in 0.7). This example uses a timer, you'd adapt this idea to instead issue a count. You can use threadlocal variables or similar to pull out/reset the count of statements after an execution: http://www.sqlalchemy.org/trac/wiki/UsageRecipes/Profiling > > Regards > NiL > > -- > You received this message because you are subscribed to the Google Groups > "sqlalchemy" group. > To post to this group, send email to sqlalchemy@googlegroups.com. > To unsubscribe from this group, send email to > sqlalchemy+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/sqlalchemy?hl=en. > -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
