Chapter 2: The Embedded SQL Interface

Application development using Embedded SQL

Development process overview

Development process overview

Once the program has been successfully preprocessed and compiled, it is linked with the import library for the Adaptive Server Anywhere interface library to form an executable file. When the database is running, this executable file will use the Adaptive Server Anywhere DLL to interact with the database. The database does not have to be running when the program is preprocessed.

One Windows 3.x import library works for all compilers and memory models. One OS/2 import library works for all compilers and memory models. For Windows 95 and Windows NT, there are separate import libraries for Watcom C/C++, for Microsoft Visual C++, and for Borland C++.

Watcom C/C++ supports 32-bit application development under Windows 3.x. For this environment, a static interface library (not a DLL) is provided.

Using import libraries is the standard development method for applications that call functions in DLLs. Adaptive Server Anywhere also provides an alternative, and recommended, method, which avoids the use of import libraries. For more information, see Loading the interface library dynamically .
