This chapter describes the global variables, in alphabetical order, available in Prolifics's database drivers.
A reference page for each global variable includes:
Since some variables store engine-specific values, refer to "Database Drivers" for additional information. For more information on using the global variables as part of your error processing, refer to Chapter 37, "Processing Application Errors," in Application Development Guide.
Variable Overview |  |
The global variables available through Prolifics's database drivers are automatically defined at initialization. All the global variable names used in the database drivers begin with the characters @dm. Since the character @ is not permitted in user-defined Prolifics variables, these variables will never conflict with any screen, LDB or JPL variables defined by your application.
These variables and their values are available to JPL commands and to Prolifics library functions like sm_getfield and sm_fptr.
The variables are automatically maintained by Prolifics. Before executing a DBMS command, Prolifics clears the contents of all its global variables. After executing the command and before returning control to the application, Prolifics updates the variables to indicate the current status.
