sql server 2008 - rollback did not happen with save transaction -


i have 3 questions.

first can tell me why rollback of save transaction did not happen. had entered error 1/0 after delete #t2 in second block of try..catch statement.

second if example procedure t1 calls procedure t2 , there error in t2 procedure outer transaction rolled in case use xact_abort off.can commit transaction.

my third question possible commit save transaction , not entire transaction.

if exists(select * tempdb.information_schema.tables table_name    '%#t1%') begin     drop table #t1     drop table #t2     drop table #t3     drop table #t4     drop table #t5 end  create table #t1(c int); create table #t2(c int); create table #t3(c int); create table #t4(c int); create table #t5(c int);  insert #t1 select 1; insert #t2 select 1; insert #t3 select 1; insert #t4 select 1; insert #t5 select 1; begin transaction  begin try delete #t1     --step 1 end try  begin catch rollback transaction end catch  if @@error = 0  begin save transaction t1 end  begin try delete #t2      ---step 2 select 1/0 end try  begin catch rollback transaction t1 commit transaction end catch

i figure out reason why rollback t1 transaction looked not happening that's because saving transaction after deleting table #t1 , showing null values.its working fine without save transaction. thanks

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
