what exception?
to see what really happens in there, temporarily change *all*
"except:" clauses to
except "foo":
and run your script again, and let us know what it prints.
when you've done that, change the except clauses to
except Sybase.Error:
(you should only use catch-all except clauses if you report the error
in some other way; e.g. by inspecting sys.exc_info, or by using the
traceback module. using catch-all to hide errors from yourself is a
rather lousy idea)
if you want to do things in a more pythonic way, remove *both*
try-except clauses from the x_dml function, and leave it to the
caller to use try-except to look for errors:
import Sybase as DB
conn = DB.connect(DSN) ....
def x_dml(SQL,conn):
c = conn.cursor()
c.execute(SQL)
res = c.rowcount
conn.commit()
return res
...
try:
r = x_dml(stmt,db)
except DB.Error, v:
print "some error", v
else:
print r, "rows updated"
</F>
