php - Multiple Select statements into an Insert statement -


i've been searching while , i'm not sure if allowed in mysql.

i know allowed in mysql

insert 'table' (column1, column2, column3) select val1, val2, val3 sometable

also this

insert 'table' (column1, column2, column3) values (val1, val2, val3), (val1, val2, val3)

i not sure if allowed though:

insert 'table' (column1, column2, column3) select val1, val2, val3 sometable, select val1, val2, val3 sometable

obviously gave me error, allowed in mysql?

you can try it, , fail. use union all instead of ,:

insert table (column1, column2, column3)     select val1, val2, val3 sometable     union     select val1, val2, val3 sometable;

i assume single quotes there sort of effect, because first 2 queries work.

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
