Question

我有一个由整数索引的整数关联数组，我希望能够在select的where子句中使用它。类似的东西：

TYPE myAssocArray IS TABLE OF PLS_INTEGER NOT NULL INDEX BY PLS_INTEGER;

SELECT * FROM MyTable WHERE MyTable_Column IN (SELECT * FROM TABLE(myAssocArray.keys))

和价值观相同。据我所知，这不是直接可能的，因为关联数组不是SQL类型。有没有正确的方法来解决这个限制？提前感谢所有建议！

创建sql级嵌套表集合。并将密钥从AssocArray复制到集合中。

create type l_number is table of number;


declare
   TYPE myAssocArray IS TABLE OF PLS_INTEGER NOT NULL INDEX BY PLS_INTEGER;
   arr myAssocArray;
   vKey PLS_INTEGER; 
   keys_list l_number := l_number();
begin
  arr(1) := 1;
  arr(5) := 1;
  arr(6) := 1;

  vKey := arr.first();

  while vKey is not null loop
    keys_list.extend(1);
    keys_list(keys_list.count) := vKey;
    vKey := arr.next(vKey);
  end loop;

  for rec in ( select column_value from table(keys_list)) loop
   dbms_output.put_line(rec.column_value);
  end loop;

end;
