Question

我是oracle的新手用户，我正在创建一个存储过程来显示表中的数据，因为我的教学过程需要它。起初我运行了我的查询。

Create or replace procedure p_ mostrar 
Is 
Begin 
Select ID_MODULO, NOMBRE, URL, ESTADO, ICONO FROM MODULO WHERE ESTADO=1 ; 
Commit; 
End p_mostrar;

他向我抛出了以下错误：

The judgment was expected INTO" After some research changed the syntax and run it as follows:

Create or replace procedure p_ mostrar (C1 out sys_refcursor) 
Is 
Begin Open C1 for Select ID_MODULO, NOMBRE, URL, ESTADO, ICONO 
FROM MODULO 
WHERE ESTADO=1 ; 
Commit; 
End p_mostrar;

我认为运行正常。但现在它不知道如何运行该程序。我提前感谢你，并期待迅速的回应。请记住，我正在学习Oracle SQL Developer。

Answer 1

这应该有效：

var result refcursor
execute p_ mostrar(:result)

Answer 2

当您在存储过程中处理select语句时，需要在select语句中包含 INTO 子句以将值存储在变量中。试试这个

CREATE OR REPLACE PROCEDURE p_mostrar 
IS

v_id_modulo modulo.id_modulo%TYPE;
v_nombre    modulo.nombre%TYPE;
v_url       modulo.url%TYPE;
v_estado    modulo.estado%TYPE;
v_icono     modulo.icono%TYPE;

BEGIN 

SELECT id_modulo, nombre, url, estado, icono 
INTO v_id_modulo, v_nombre, v_url, v_estado, v_icono --needed to catch the values selected and store it to declared variables
FROM modulo                                          
WHERE estado=1 ;                                     
Commit; -- i dont think this is necessary, you use commit statement only when you use DML statements to manage the changes made 

dbms_output.put_line(v_id_modulo||' '|| v_nombre||' '||v_url||' '||v_estado||' '||v_icono); --used to display the values stored in the variables


END;

如何创建一个存储过程，包括＆＃34; SELECT＆＃34;在Oracle SQL Developer中？
