Function to returns the total value of a column for a matching series of keys


Syntax

SUMVALUES(<expN> [[, <for condition> [, <key expression>]] [,<tag name or indexorder>] )

See Also

AVERAGE, COUNT, SUM, TOTAL, AMAX(), AMIN(), AVGVALUES(), CNTVALUES(), MAX(), MAXVALUES(), MIN(), MINVALUES(), SQLVALUES(), ALLVALUES()

Description

The SUMVALUES() function returns the total value of <expN> for a matching series of keys. The required <expN> parameter should be a numeric expression referencing columna from the current workarea (or cursor). If none of the optional parameters is specified, then the keys matching the current key is scanned. An optional <for condition> can be specified to restrict the rows included in the sum operation. You can also optionally specify a <key expression> to perform the sum on instead of the current key. An optional <tag name or index order> can be specified also.

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

Example

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