CUT NAMED SELECTION ( {aTable ;} name )
| Parameter | Type | Description | |
|---|---|---|---|
| aTable | Table | → | Table from which to cut selection, or Default table, if omitted |
| name | Text | → | Name of the named selection to create |
Description
CUT NAMED SELECTION creates a named selection name and moves the current selection of aTable to it. This command differs from COPY NAMED SELECTION in that it does not copy the current selection, but moves the current selection of table itself.
After the command has been executed, the current selection of aTable in the current process becomes empty. Therefore, CUT NAMED SELECTION should not be used while a record is being modified.
CUT NAMED SELECTION is more memory efficient than COPY NAMED SELECTION. With COPY NAMED SELECTION, 4 bytes times the number of selected records is duplicated in memory. With CUT NAMED SELECTION, only the reference to the list is moved.
Example
The following method empties the current selection of a table [Customers]:
CUT NAMED SELECTION([Customers];"ToBeCleared")
CLEAR NAMED SELECTION("ToBeCleared")
