[WHILE <condition>]
See Also
ACC(), AVERAGE, CALC(), LOCATE, SEEK, SET DELETED, SET FILTER, SUM, TOTAL
Description
The COUNT command counts the number of records in the active table. If no <scope> is specified, ALL records will be counted. If SET FILTER TO is in effect, then only those records that satisfy the filter <condition> are counted. If SET DELETED is ON, then records marked for deletion will not be included in the COUNT.
FOR <condition>
If the for <condition> is used then only the records that satisfy the specified <condition> are counted.
TO <memvar>
Using the TO <memvar> clause causes the result of the COUNT operation to be stored in the specified memory variable.
WHILE <condition>
The WHILE clause can be used in conjunction with the SEEK or LOCATE commands to restrict the range of records counted. When the WHILE option is used the <scope> defaults to REST.
Example
use patrons count to nResult for event = "CHOPIN" and date = date()
Products
Recital Server, Recital
