During the design of MySQL database fields today, the prompt is always prompted during table creation.MySQL:Error 1071 (42000): specified key was too long; max key length is 767 bytes.At first, I didn't figure out why, because by default, MySQL restricts the length of the varchar type to between 0 and 65535. Later, I checked other attributes of this field carefully, if the unique attribute is removed, no such error message is returned, which complies with the 65535-byte length limit described in

To find the number of bytes occupied by various data types can call the sizeof function, to find the maximum value of various data types can be called Limits standard library Numeric_limits#include bytes of various data types in C + +

In Java's basic data type, the Boolean has only two states and the default value is False. The value range is {True,false}, which theoretically accounts for 1bit, actually:1. A single Boolean type variable is used when compiling the int type.Boolean a=true;//This A is 4 bytes in the JVM: 32 bits.An array of type 2.boolean is compiled as a byte array at compile time, so each element in the Boolean array takes one byte,Boolean[] B = new boolean[10];//ar

Python3 does not mix str and bytes in any implicit way, which makes the distinction between the two particularly clear, that when using Python, you cannot stitch strings and byte packets, or search for strings inside a byte packet (and vice versa). It is also not possible to tell a string to pass in a function that has a byte packet (or vice versa). In any case, the boundary between the string and the byte packet is inevitable, which is to explain the
