Description

The MINVALUES() function returns the minimum value of <expN> for a matching series of keys. The required <expN> parameter must be a column name from a table. If none of the optional parameters are specified, then the minimum value of keys matching the current key is returned. An optional <for condition> can be specified to restrict the rows included in the operation. You can also optionally specify a <key expression> to be used instead of the current key.

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

Example

use customer order title 
// Minimum value of balance column for the number of records matching the current key
total_balance = minvalues(balance) 
// Minimum value of balance column for the number of records matching the key "Mr"
m_male = minvalues(balance, .T., "Mr")
// Minimum value of balance column for the number of records matching the current key with an expiry date < today
m_expired = minvalues(balance, expiry<date())
