我在PL / SQL包中声明了以下类型:
TYPE t_simple_object IS RECORD (
wert NUMBER,
gs NUMBER,
vl NUMBER);
TYPE t_obj_table IS TABLE OF t_simple_object
INDEX BY BINARY_INTEGER;
然后我宣布一个变量:
obj t_obj_table;
但是,当我想使用变量时,我无法初始化或扩展它:
obj := t_obj_table ();
给出以下错误:
PLS-00222: no function with name 'T_OBJ_TABLE' exists in this scope
如果我没有初始化它,我无法扩展它以添加一些日期
obj.EXTEND();
给出了另一个错误:
PLS-00306: wrong number or types of arguments in call to 'EXTEND'
我该如何做到这一点?

你没有扩展一个由“某事”索引的表,你可以使用它......
DECLARE
TYPE t_simple_object IS RECORD
( wert NUMBER
, gs NUMBER
, vl NUMBER
);
TYPE t_obj_table IS TABLE OF t_simple_object
INDEX BY BINARY_INTEGER;
my_rec t_simple_object;
obj t_obj_table;
BEGIN
my_rec.wert := 1;
my_rec.gs := 1;
my_rec.vl := 1;
obj(1) := my_rec;
END;
/
要使用EXTEND语法,此示例应该这样做......
DECLARE
TYPE t_simple_object IS RECORD
( wert NUMBER
, gs NUMBER
, vl NUMBER
);
TYPE t_obj_table IS TABLE OF t_simple_object;
my_rec t_simple_object;
obj t_obj_table := t_obj_table();
BEGIN
obj.EXTEND;
my_rec.wert := 1;
my_rec.gs := 1;
my_rec.vl := 1;
obj(1) := my_rec;
END;
/

您无法扩展关联数组。 只需为其指定值
declare
TYPE t_simple_object IS RECORD (
wert NUMBER,
gs NUMBER,
vl NUMBER);
TYPE t_obj_table IS TABLE OF t_simple_object INDEX BY BINARY_INTEGER;
simple_object t_simple_object;
begin
simple_object.wert := 1;
simple_object.gs := 2;
simple_object.vl := 3;
obj(1) := simple_object;
end;

如果您不想使用关联数组(也就是索引表),则省略“INDEX BY BINARY_INTEGER”子句。然后您的代码可以正常工作:
declare
TYPE t_simple_object IS RECORD (
wert NUMBER,
gs NUMBER,
vl NUMBER);
TYPE t_obj_table IS TABLE OF t_simple_object;
obj t_obj_table;
begin
obj := t_obj_table ();
obj.EXTEND();
end;

或者只使用记录(或关联的记录数组)
create or replace package p_test is
type t_rec is record (
empname varchar2(50),
empaddr varchar2(50));
function p_test_ret_record return t_rec;
end p_test;
create or replace package body p_test is
function p_test_ret_record return t_rec is
l_rec t_rec;
begin
l_rec.empname := 'P1';
l_rec.empaddr := 'P2';
return l_rec;
end;
end p_test;
declare
-- Non-scalar parameters require additional processing
result p_test.t_rec;
begin
-- Call the function
result := p_test.p_test_ret_record;
dbms_output.put_line('Name: ' || result.empname || ' Addr: ' || result.empaddr);
end;
