Description

The CNTVALUES() function returns the number of records matching a series of keys. If no parameters are specified then the number of keys matching the current key is returned. An optional <for condition> can be specified to restrict the key count. You can also optionally specify a <key-expression> to perform the count on instead of the current key.

After completion, all record pointers and indexes are returned to their original positions.

Example

use customer order title 
// Number of records matching the current key
count = cntvalues()
// Number of records matching the key "Mr"
m_male = cntvalues(.T., "Mr")
// Number of records matching the current key with an expiry date < today
m_expired = cntvalues(expiry < date())
