Detailed Description

template<typename VT = signed char>
class mysqlpp::tiny_int< VT >

Class for holding an SQL TINYINT value.

This is required because the closest C++ type, char, doesn't have all the right semantics. For one, inserting a char into a stream won't give you a number. For another, if you don't specify signedness explicitly, C++ doesn't give a default, so it's signed on some platforms, unsigned on others.

The template parameter is intended to allow instantiating it as tiny_int<unsigned char> to hold TINYINT UNSIGNED values. There's nothing stopping you from using any other integer type if you want to be perverse, but please don't do that.

Several of the functions below accept an int argument, but internally we store the data as a char by default. Beware of integer overflows!
