COUNT

COUNT

Tally records to a variable

Syntax

      COUNT TO <idVar>
             [<scope>] [WHILE <lCondition>] [FOR <lCondition>]

Arguments

TO <idVar> identifies the variable that holds the COUNT result. A variable that either does not exist or is invisible is created as a private variable whose scope is the current procedure.

<scope> is the portion of the current database file to COUNT. The default is ALL records.

WHILE <lCondition> specifies the set of records meeting the condition from the current record until the condition fails.

FOR <lCondition> specifies the conditional set of records to COUNT within the given scope.

Description

COUNT tallies the number of records from the current work area that match the specified record scope and conditions. The result is then placed in the specified variable. <idVar> can be a variable of any storage class including a field.

Examples

      .  This example demonstrates a COUNT of Branches in Sales.dbf:
      USE Sales NEW
      COUNT TO nBranchCnt FOR Branch = 100
      ? nBranchCnt                           // Result: 4
      .  This example tallies the number of records in Sales.dbf whose
      Branch has the value of 100 and assigns the result to the Count field
      in Branch.dbf for branch 100:
      USE Branch INDEX Branch NEW
      SEEK 100
      USE Sales INDEX SalesBranch NEW
      SEEK 100
      COUNT TO Branch->Count WHILE Branch = 100
