数据库开发高手请进
大家好,请教个问题
我在plsql   中如是定义数组并初始化:
create   procedure   ...
is
  type   type_record     is   table   of   varchar2(100);
      lv_procedure   type_record   :=   new   type_record();
begin
      ...
end
为何这行会报错lv_procedure   type_record   :=   new   type_record();
Compilation   errors   for   PACKAGE   BODY   DEVBUS.PKG_REPORT_TRANSFER

Error:   PLS-00103:   出现符号   "TYPE_RECORD "在需要下列之一时:
              .(*@%&=-+; </> atin
                    modnotrem <an   exponent   (**)> <>   or   !=   or   ~=> = <= <> andorlike
                    betweenis   nullis   not||is   dangling
              符号   ". "   被替换为   "TYPE_RECORD "   后继续。

---------------------- 单维数组 ------------------------
DECLARE
TYPE emp_ssn_array IS TABLE OF NUMBER
INDEX BY BINARY_INTEGER;

best_employees emp_ssn_array;
worst_employees emp_ssn_array;

BEGIN
best_employees(1) := '123456 ';
best_employees(2) := '888888 ';

worst_employees(1) := '222222 ';
worst_employees(2) := '666666 ';

FOR i IN 1..best_employees.count LOOP
DBMS_OUTPUT.PUT_LINE( 'i= '|| i || ', best_employees= ' ||best_employees(i)
|| ', worst_employees= ' ||worst_employees(i));
END LOOP;

END;


---------------------- 多维数组 ------------------------


DECLARE

TYPE emp_type IS RECORD
( emp_id employee_table.emp_id%TYPE,
emp_name employee_table.emp_name%TYPE,
emp_gender employee_table.emp_gender%TYPE );

TYPE emp_type_array IS TABLE OF
emp_type INDEX BY BINARY_INTEGER;

emp_rec_array emp_type_array;
emp_rec emp_type;

BEGIN
emp_rec.emp_id := 300000000;
emp_rec.emp_name := 'Barbara ';
emp_rec.emp_gender := 'Female ';

emp_rec_array(1) := emp_rec;

emp_rec.emp_id := 300000008;
emp_rec.emp_name := 'Rick ';
emp_rec.emp_gender := 'Male ';

emp_rec_array(2) := emp_rec;

FOR i IN 1..emp_rec_array.count LOOP
DBMS_OUTPUT.PUT_LINE( 'i= '||i
|| ', emp_id = '||emp_rec_array(i).emp_id
|| ', emp_name = '||emp_rec_array(i).emp_name
|| ', emp_gender = '||emp_rec_array(i).emp_gender);
END LOOP;

END;
-------------- Result --------------
i=1, emp_id =300000000, emp_name =Barbara, emp_gender = Female
i=2, emp_id =300000008, emp_name =Rick, emp_gender = Male
