無法調用Oracle函數

Question

我有一個包含一個函數的包，如下所示，它需要其中一個參數是數組。

create or replace PACKAGE selected_pkg IS 

TYPE NUM_ARRAY IS TABLE OF NUMBER; 

FUNCTION get_selected_kml(
    in_layer  IN NUMBER, 
    in_solm_id  IN NUMBER, 
    in_feature_ids IN NUM_ARRAY, 
    in_lx   IN NUMBER, 
    in_ly   IN NUMBER, 
    in_ux   IN NUMBER, 
    in_uy   IN NUMBER) 
RETURN CLOB; 

END selected_pkg; 

現在我想從下面的匿名塊調用函數：

declare 
    result CLOB; 
    TYPE NUM_ARRAY1 IS TABLE OF NUMBER; 
    myarray NUM_ARRAY1 := NUM_ARRAY1(); 
begin 
    myarray.extend(3); 
    myarray(1) := 1; 
    myarray(2) := 5; 
    myarray(3) := 9; 
    EXECUTE IMMEDIATE 'truncate table demoresult'; 
    result:=SELECTED_PKG.get_selected_kml(103, 19, myarray, 4.11, 56.27, 4.59, 56.39); 
    insert into demoresult values(result); 
    COMMIT; 
end; 

我收到錯誤

PLS-00306: wrong number or types of arguments in call to 'GET_SELECTED_KML'

可能有人請建議我，我究竟做錯了什麼？

感謝， Alankar

您需要使用您的函數需要

declare 
    result CLOB; 
    myarray selected_pkg.num_array := selected_pkg.num_array(); 
begin 
    myarray.extend(3); 
    myarray(1) := 1; 
    myarray(2) := 5; 
    myarray(3) := 9; 
    EXECUTE IMMEDIATE 'truncate table demoresult'; 
    result:=SELECTED_PKG.get_selected_kml(103, 19, myarray, 4.11, 56.27, 4.59, 56.39); 
    insert into demoresult values(result); 
    COMMIT; 
end;
