创建显性游标:
create or replace procedure test
is
cursor test1 is select
name from devp;
test2 devp.name%type;
begin
open
test1;
loop
fetch test1 into test2;
dbms_output.put_line(test2);
--注意,此处用的是test2变量
exit when test1%notfound;
end loop;
close
test1;
end;
/
create or replace procedure test
is
cursor
test1 is select name from devp;
test2 test1%rowtype;
begin
open
test1;
loop
fetch test1 into test2;
dbms_output.put_line(test2.name);
--注意,此处用的是test2.name
exit when test1%notfound;
end loop;
close
test1;
end;
/
下面用隐性游标试一下:
create or replace procedure test
is
cursor test1 is select name from devp;
test2
devp.name%type;
begin
for test2 in test1
loop
dbms_output.put_line(test2.name); --注意,此处用的是test2.name
end
loop;
end;
/
create or replace procedure test
is
cursor
test1 is select name from devp;
test2 test1%rowtype;
begin
for test2 in
test1 loop
dbms_output.put_line(test2.name); --注意,此处用的是test2.name
end
loop;
end;
/
由于使用的游标的不同,我们最终在使用变量的时候还是有一些小区别的。希望大家以后在调代码的时候少走弯路。[@more@]
