USE ENTITY SELECTION
| USE ENTITY SELECTION ( entitySelection ) | ||||||||
| Parameter | Type | Description | ||||||
| entitySelection | EntitySelection |
|
An entity selection | |||||
The USE ENTITY SELECTION command updates the current selection of the table matching the dataclass of the entitySelection parameter, according to the content of the entity selection.
This command only works with the local or client/server datastore returned by ds.
Note: After a call to USE ENTITY SELECTION, the first record of the updated current selection (if not empty) becomes the current record, but it is not loaded in memory. If you need to use the values of the fields in the current record, use the LOAD RECORD command after the USE ENTITY SELECTION command.
C_OBJECT($entitySel)
$entitySel:=ds.Employee.query("lastName = :1";"M@") //$entitySel is related to the Employee dataclass
REDUCE SELECTION([Employee];0)
USE ENTITY SELECTION($entitySel) //The current selection of the Employee table is updated
