RFC1

Complete support for C++ integer types

• Author: Mateusz Loskot
• Date: (not proposed yet)
• Version: 4.0.0
• Status: development

Main purpose of this proposal is to:

• clarify status of C++ integer types supported by use() and into()
• decide on what C++ integer types should be supported in SOCI
• propose implementation of type conversions
• describe handling of boundary and corner cases, and any heuristics involved

in order to provide required C++ integer types support for all database backends available in SOCI.

Exact-width integer types

• TODO: Decide on C++03 integer types support

The following table presents mapping of C++ integer types to corresponding SQL types planned to implement in SOCI. If direct mapping is not possible, an appropriate conversion should be implemented, with careful explanation of how it handles edge cases, integer overflow and errors.

C++11	ANSI SQL	Firebird	ODBC	Oracle	MySQL	PostgreSQL	SQLite3
int8_t
uint8_t
int16_t
uint16_t
int32_t
uint32_t
int64_t
uint64_t
