  • Artikkeli

Version: Available or changed with runtime version 1.0.

Gets the minimum value in a range for a field.

Syntax

Value :=   FieldRef.GetRangeMin()

Note

This method can be invoked using property access syntax.

Parameters

FieldRef
 Type: FieldRef
An instance of the FieldRef data type.

Return Value

Value
 Type: Any

Remarks

This method is like the GetRangeMin Method (Record) method.

Example

The following example opens the Customer table as RecordRef variable, creates a FieldRef for the first field (No.) and stores the reference in the MyFieldRef variable. The SetFilter Method (FieldRef) sets a filter that selects records in the range 10000 to 40000 from the No. field. The GetRangeMin method retrieves and stores the minimum value that is set in the filter, stores the value in the varMin variable and displays it in a message box. The varMin variable contains 10000 which is the minimum value that is set in the filter.

var
    MyFieldRef: FieldRef;
    CustomerRecref: RecordRef;
    varMin: Text;
    Text000: Label 'The minimum value in the filter is %1.';
begin
    CustomerRecref.Open(Database::Customer);  
    MyFieldRef := CustomerRecref.Field(1);  
    MyFieldRef.SetFilter('10000..40000');  
    varMin := MyFieldRef.GetRangeMin();  
    Message(Text000, varMin);  
end;
