Description
The MAXVALUES() function returns the maximum value of the <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 is specified, then the maximum 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 return the maximum value from instead of the current key.
After completion, all record pointers and indexes are returned to their original positions.
Example
use customer order title // Maximum value of balance column for the number of records matching the current key total_balance = maxvalues(balance) // Maximum value of balance column for the number of records matching the key "Mr" m_male = maxvalues(balance, .T., "Mr") // Maximum value of balance column for the number of records matching the current key with an expiry date < today m_expired = maxvalues(balance, expiry<date())
