_TALLY System Variable

  • Makale

Contains the number of records processed by the most recently executed table command.

_TALLY = nRecords

Parameters

  • nRecords
    Contains a numeric value indicating the number of records processed by the most recently executed table command. When you start Visual FoxPro, _TALLY is set to zero (0).

Remarks

Certain table processing commands return information about their status while they execute. When such a command finishes executing, it displays the number of records processed if the SET TALK command is set to ON. If the command is executed against local views and tables, it stores this number to the _TALLY system variable.

The INSERT - SQL command changes _TALLY if a SQL SELECT command is used to specify the data to insert.

The following table lists the commands and functions that return status information and store the number of records processed in _TALLY only when executed against local tables and views.

Example

   WHERE country = 'USA' ;
   INTO CURSOR temp
? _TALLY
