Function DbeList() Foundation

Returns the loaded database engines (DBE).

Syntax
DbeList() --> aDBElist
Return

The return value of DbeList() is a two dimensional array containing information about loaded DBEs. The structure of the array is shown in the following table:

Structure of the DbeList() array
Column Contents Data type
1 Name of the loaded DBE C
2 Hidden flag L

When no database engines are loaded, the function returns an empty array.

Description

The function DbeList() is used to determine which database engines (DBEs) are currently loaded and available. In Xbase++, DBEs can be loaded and also released during runtime of a program. This is done using the functions DbeLoad() and DbeUnload(). When a DBE was loaded as "hidden", it cannot be used directly for file management and is only available as an individual component for generating a new compound DBE. New compound DBEs are created using the function DbeBuild().

Examples
DbeList() 
// The example lists the names of the loaded DBEs 
// as well as their status. 

PROCEDURE Main 
   LOCAL aDBE := DbeList() 

   AEval( aDBE, {|a| QOut(a[1], a[2]) } ) 
RETURN
