PRB: Function Requires Row or Table Buffering Mode

ID: Q128206

3.00 WINDOWS kbprg kbprb

The information in this article applies to:

• Microsoft Visual FoxPro for Windows, version 3.0

SYMPTOMS

Issuing a command or function that requires buffering, without enabling buffering first, causes the following error to occur:

   Error number 1586 "Function requires row or table buffering mode"

CAUSE

A command or function, such as TABLEUPDATE() or TABLEREVERT(), that requires buffering to be enabled has been issued.

RESOLUTION

Enable buffering to resolve this problem. The on error routine listed below can be used to set the default buffering mode programatically if this error occurs:

   ON ERROR DO errhandler

   PROCEDURE errhandler

      =aerror(aLastError)
      DO CASE
         CASE aLastError(1) = 1586
            SET MULTILOCKS ON
            =Cursorsetprop("Buffering",5)
            RETRY
      ENDCASE

MORE INFORMATION

An on error routine can handle a variety of errors that may occur during processing. Include an OTHERWISE section within the DO CASE construct to handle errors that are not specifically included in the on error routine.
