oracle bulk load

First create types in oracle

DROP TYPE CINBELLINP.D_TABLE;

CREATE OR REPLACE TYPE CINBELLINP.d_table is table of Date;
/

DROP TYPE CINBELLINP.I_TABLE;

CREATE OR REPLACE TYPE CINBELLINP.i_table is table of number(10);
/

DROP TYPE CINBELLINP.V_TABLE;

CREATE OR REPLACE TYPE CINBELLINP.v_table is table of varchar2(10);
/

second, create procedure

CREATE OR REPLACE procedure CINBELLINP.pro_forall_insert(v_1 i_table,v_2 v_table, v_3 d_table)
as
begin

forall i in 1.. v_1.count
insert into a values(v_1(i),v_2(i), v_3(i));
end;
/
