我想创建一个模式级别的 VARRAY，以便我可以将它作为输入参数传递到过程中

Question

这是我一直在尝试的-

create or replace type persons_list is varray(10) of varchar(1) not null;

Declare
peoplesList persons_list := persons_list(1, 2, 3, 4, 5, 6, 7, 8, 9, 'a');

Begin
dbms_output.put_line('hello');

End;
/

但我一直收到这个错误-

Type PERSONS_LIST compiled

LINE/COL  ERROR
--------- -------------------------------------------------------------
3/1       PLS-00103: Encountered the symbol "DECLARE" 
10/0      PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following:     ( begin case declare end exception exit for goto if loop mod    null pragma raise return select update while with    <an identifier> <a double-quoted delimited-identifier>    <a bind variable> << continue close current delete fetch lock    insert open rollback savepoint set sql execute commit forall    merge pipe purge

它是一个缺少的斜杠，它终止了 CREATE TYPE 语句：

SQL> create or replace type persons_list is varray(10) of varchar(1) not null;
  2  /                   --> this is what you are missing

Type created.

SQL> Declare
  2  peoplesList persons_list := persons_list(1, 2, 3, 4, 5, 6, 7, 8, 9, 'a');
  3
  4  Begin
  5  dbms_output.put_line('hello');
  6
  7  End;
  8  /
hello

PL/SQL procedure successfully completed.

或者，您甚至不必声明自己的类型 - 使用 Oracle 中已经内置的类型：sys.odcivarchar2list（如果没有最后一个 'a'，您可以已使用 sys.odcinumberlist):

SQL> Declare
  2  peoplesList sys.odcivarchar2list := sys.odcivarchar2list(1, 2, 3, 4, 5, 6, 7, 8, 9, 'a');
  3
  4  Begin
  5  dbms_output.put_line('hello');
  6
  7  End;
  8  /
hello

PL/SQL procedure successfully completed.

在新行用斜杠替换第一个分号就足够了:

create or replace type persons_list is varray(10) of varchar(1) not null
/
Declare
    peoplesList persons_list := persons_list(1, 2, 3, 4, 5, 6, 7, 8, 9, 'a');
Begin
    dbms_output.put_line('hello');
End;
/

我想创建一个模式级别的 VARRAY，以便我可以将它作为输入参数传递到过程中

I want to create a VARRAY that is on the schema level, so that I can pass it as an input parameter into a procedure

sql

oracle

plsql

varray
