*/

DECLARE
TYPE myrec IS RECORD (
x varchar2(10),
y varchar2(10),
z varchar2(10));

TYPE mytable is TABLE OF myrec
INDEX BY BINARY_INTEGER;

TableXYZ mytable;
Range OleVar;
Value OleVar;



BEGIN
/* Find the range of cells you want to interact with */
Range := EXCEL_WORKSHEET.ole_Range(
:CTRL.interface,
To_Variant('A1:C3'));

/* Get the value of cells in the range from A1 to C3 */
Value := EXCEL_RANGE.Value(Var_tbj(Range));

/* Populate PL/SQL Table; can access cell values using PL/SQL Syntax such as TableXYZ(1).x, TableXYZ(1).y, TableXYZ(2).x, TableXYZ(2).y, etc. */
Var_to_Table(Value,TableXYZ);
