Programming with ESQL

How you program with ESQL depends on whether your application requires only static ESQL, dynamic ESQL, or a combination of both. If you specify your SQL statements at compile time and use only static ESQL, you must write your application using Progress/ESQL, and then preprocess your source files to generate the required ESQL-LIB function calls.

To specify SQL statements at run time (requiring dynamic ESQL), you can write a combination of Progress/ESQL and direct ESQL-LIB function calls that you preprocess to generate the remaining calls to ESQL-LIB, or you can completely implement the application with direct ESQL-LIB function calls without preprocessing.

To complete an application using either static or dynamic ESQL, you write some direct ESQL-LIB function calls to manage the interaction between your application and Progress. This chapter provides information on performing all of these tasks, including:
