先建好表，然后写带输出参数的存储过程
CREATE OR REPLACE PROCEDURE "MES"."MES_GETKEY" (KName IN
VARCHAR2,KValue OUT VARCHAR2) AS
BEGIN
select KeyValue into KValue from MES_SYSTEMKEY where Keyname=KName;
end MES_GetKey;
VARCHAR2,KValue OUT VARCHAR2) AS
BEGIN
select KeyValue into KValue from MES_SYSTEMKEY where Keyname=KName;
end MES_GetKey;
然后运行
var c varchar2(50);
exec MES.MES_GETKEY('PRODUCE_NO',:c)
PRINT c;
就可以看到输出结果了，如果用的是 PL/SQL Developer，在命令窗口运行即可
