不要连Sybase11，直接连SYBASE即可，DLL选用SQLSSC32.DLL

64位BDE+sybase客户端本人WIN7+64位测试通过，其它未测试。

BDE是宝兰公司的数据库引擎，BDE给我们提供了和数据库交流的接口，它成功的把应用程序接口和连接数据库部分分开，就方便了程序的移植。 BDE(Borland Database Engine)是borland公司的数据库引擎，它结合了SQL Links允许程序员通过它能够连接到各种不同的数据库（例如oralce,sybase,sql server等）。许多人装了Delphi,发现没有附带BDE,那么需要开发BDE应用的朋友就肯定需要elphi7 bde了，为此东坡为您提供了一个Delphi7 bde独立安装版，方便您对数据库的开发了。数据库引擎BDE主要作用: 数据库引擎BDE主要作用： 1、其应用程序运行效率非常高; 2、BDE通过提供安装相应驱动程序的方式来支持相应数据库的访问能力!因此Delphi数据库应用程序能访问多种类型的数据库!而不是局限于一种数据库!从而Delphi对分布式数据库应用程序编写有很强的支持能力; 3、以提供组件的方式支持数据库编程!编程非常直观、简单； 4、对数据库应用程序(特别是在网络环境下)安装过程中的配置管理非常方便; BDE截图:

使用delphi 6,sybase测试数据库源码其中数据库配置信息测试时需要修改。在数据库多线程编程时，要注意的就是每个线程的数据库组件都要有个独立的TSession对象，线程主要工作是，运行是创建相关对象，并查询数据，结束时，析构申请的资源。

Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, Delphi for .NET, C++Builder, and Free Pascal. The UniDAC library is designed to help programmers develop faster and cleaner cross-database applications. UniDAC is a complete replacement for standard database connectivity solutions and presents an efficient native alternative to the Borland Database Engine and dbExpress for access to Oracle, SQL Server, MySQL, InterBase, Firebird, SQLite, DB2, Microsoft Access, Advantage Database Server, Adaptive Server Enterprise, and other databases (using ODBC provider). UniDAC is based on the well-known Data Access Components from Devart such as ODAC, SDAC, MyDAC, IBDAC, and PgDAC. We have joined the experience of long-term successful development into one great product which provides unified access to popular databases such as Oracle, Microsoft SQL Server, MySQL, InterBase, Firebird, SQLite, DB2, Microsoft Access, Advantage Database Server, Adaptive Server Enterprise, and other databases (using ODBC provider). The UniDAC library is actively developed and supported by Devart Team. If you have questions about UniDAC, email the developers at unidac@devart.com or visit UniDAC online at http://www.devart.com/unidac/. Advantages of UniDAC Technology UniDAC is very convenient in setup and usage. It provides transparent server-independent interface for working with different databases. Selected database provider ensures the best way to perform operations on the server. Universal Data Access UniDAC provides transparent server-independent interfaces for working with different databases, and lets you change the client engine for specific server type just by changing single connection option. It means that you can easily switch between database servers in your cross-database UniDAC-based application. Server-Aware Providers UniDAC chooses the best way specific to the server to perform most operations. Every UniDAC data provider uses server-specific native connectivity. All operations with data are performed by providers automatically considering peculiarities of the selected database server. Optimized Code The goal of UniDAC is to enable developers to write efficient and flexible database applications. The UniDAC library is implemented using advanced data access algorithms and optimization techniques. Classes and components undergo comprehensive performance tests and are designed to help you write high-performance, lightweight data access layers. Compatibility with Other Connectivity Methods The UniDAC interface retains compatibility with standard VCL data access components like BDE. Existing BDE-based applications can be easily migrated to UniDAC and enhanced to take advantage of server-specific features. Development and Support UniDAC is a cross-database connectivity solution that has been actively developed and supported. UniDAC comes with full documentation, demo projects, and fast (usually within one business day) technical support by the UniDAC development team. Find out more about how to get help or submit feedback and suggestions to the UniDAC development team in the Getting Support topic. A description of the UniDAC components is provided in the Component List.
