OTL介绍： OTL 是 Oracle, Odbc and DB2-CLI Template Library 的缩写，是一个C++操控关系数据库的模板库，最新版本4.0.104，参见http://otl.sourceforge.net/ 优点：a. 跨平台 b. 运行效率高，与C语言直接调用API相当 c. 开发效率高，起码比ADO.net使用起来更简单，更简洁 d. 部署容易，不需要ADO组件，不需要.net framework 等缺点： a. 只有C++才可以使用她 b. 说明以及范例不足（已附带了686个实例） This document describes the Oracle, ODBC and DB2-CLI Template Library, Version 4.0 (OTL 4.0). OTL 4.0 is a C++ library based on C++ templates. OTL 4.0 was designed as a combination of a C++ template framework and OTL-adapters. The framework is a generic implementation of the concept of OTL streams. The OTL-adapters are thin wrappers around the database APIs and are used as class type parameters to be passed into the template framework. OTL 4.0 covers the functionality of a full featured C++ database access library with just a handful of classes: otl_stream, otl_connect, otl_exception, otl_long_string, and several template PL/SQL (Oracle) table container classes, generated from the template framework and the OTL-adapters. The OTL code gets expanded into direct database API function calls, so it provides very decent performance (only 10-15% overhead, compared with the database APIs themselves) and reliability in multi-processor environments as well as traditional batch programs. OTL 4.0, being a template library, is highly portable since it is self-sufficient and compact enough. OTL 4.0 is ANSI C++ compliant (ANSI C++ typecasts, clean templatized code, etc.), tightly integrated with the Standard Template Library (STL) via STL-compliant stream iterators, and natively supports the STL std::string's in otl_stream's. OTL integrates with ACE, and supports ACE_TStrings. OTL 4.0 supports all versions of Oracle starting with 7.3 (natively via the corresponding version of the OCI), DB2 UDB LUW / zOS (natively via DB2 CLI), MS SQL Server 2005/2008 (natively via SNAC), Informix 11 (natively via Informix CLI), TimesTen 7 and higher (natively TimesTen CLI), SAP-MAX/DB (natively via SAP/DB CLI), ODBC 3.x as well as ODBC 2.5 (for legacy applications) compliant data sources in MS Windows, Linux/Unix/Mac OS X (via unixodbc and iODBC driver managers): Sybase, MySQL, PostgreSQL, EnterpriseDB, SQLite, MS ACCESS, Firebird, etc. The list of supported database back ends is growing. In the last few years, transition from the 32-bit platforms to the 64-bit platforms has occurred: OTL's source code is portable, and it support both 32-bit and 64-bit C++ compilers. Also, OTL supports UTF-8 and UTF-16 for Oracle, and UTF-16 for the rest of the database types, when the underlying database API / ODBC driver supports it.
