Progress/ESQL and ESQL-LIB
Progress/ESQL provides a portable and consistent syntax for specifying SQL statements in your application. The SQL preprocessor converts Progress/ESQL into calls to ESQL-LIB functions to implement your static or dynamic ESQL statements. However, there are additional calls to ESQL-LIB you must make yourself, even when using Progress/ESQL. These calls provide additional functionality not specified in the SQL standard, but that are necessary or useful for running an ESQL session. Examples of tasks that you can accomplish only through direct calls to ESQL-LIB are logging in and out of the session and retrieving ESQL status messages.
