mysql - What is the best data type for DATE and TIME -


i have application saves date , time of transaction. initial database design create separate fields date date , time varchar. second option have single field datetime.

what difference of these two??

i recommend use timestamp track every change made database. shou;d use datetime datatype if want store specific value of date , time in column. if want track changes made in values recommend use timestamp. mysql docs:

the datetime type used when need values contain both date , time information. mysql retrieves , displays datetime values in 'yyyy-mm-dd hh:mm:ss' format. supported range '1000-01-01 00:00:00' '9999-12-31 23:59:59'.

...

the timestamp data type has range of '1970-01-01 00:00:01' utc '2038-01-09 03:14:07' utc. has varying properties, depending on mysql version , sql mode server running in.

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
