Description
The COPY TO ARRAYOFOBJECTS command allows all or part of the active table to be copied to the specified array, <array>. The target array will be created or resized to accommodate the field list/records from the table as an array of objects.
FIELDS <field list>
The optional FIELDS clause restricts the operation to those fields listed in <field list>. The <field list> contains a comma-separated list of field names.
FOR <condition>
The optional FOR clause restricts the operation to those records that match the specified <condition>.
WHILE <condition>
The WHILE clause will copy records so long as the <condition> is true (.T.), and is used to restrict the range of records processed. When used in conjunction with the SEEK or LOCATE commands, it allows a quick way of copying selected records. When the WHILE clause is used, the <scope> will default to REST.
COPY TO ARRAYOFOBJECTS supported from Lianja v3.2.1.
Example
open database southwind use shippers copy to arrayofobjects aShipObjects for shipperid < 3 ? aShipObjects Array (refcnt=1) ( [1] = Dynarray ( [shipperid] => 1 [companyname] => Speedy Express [phone] => (503) 555-9831 ) [2] = Dynarray ( [shipperid] => 2 [companyname] => United Package [phone] => (503) 555-3199 ) )
