如何在Oracle的其他程序中調用程序，Sql Developer？

Question

CREATE OR REPLACE PROCEDURE ShowShips3Task(
     p_Register IN ship.registry_country%TYPE, 
     o_name OUT ship.ship_name%TYPE, 
     o_capitan OUT ship.captain_name%TYPE) 
IS 
    procedure showshipsDisp(
    o_cap out Ship.captain_name%type, 
    o_dis out Ship.displacement%type) 
    is 
    begin 
    Select Captain_name, Displacement 
    into o_cap, o_dis 
    from Ship Where Ship_name = 'Avrora'; 
    end; 

BEGIN 

    SELECT Ship_name , Captain_Name 
    INTO o_name, o_capitan 
    from Ship WHERE registry_country LIKE p_register || '%'; 

END; 

如何執行一個程序在同一時間內的另一個程序？

如何創建多值參數，意味着第二個程序裏面依賴於第一個程序的參數？

Answer 1

在問題嵌套過程的例子中，只聲明但從未調用。要運行嵌套過程的調用必須BEGIN和END語句之間存在：

BEGIN 

    SELECT Ship_name , Captain_Name 
    INTO o_name, o_capitan 
    from Ship WHERE registry_country LIKE p_register || '%'; 

    showshipsDisp(o_cap => ? 
       ,o_dis => ?); 

END; 

問號應該通過適當的變量來代替。
