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())
Products
