谁能告诉我是否可以在 oracle 中创建一个接受数组作为输入参数的存储过程以及如何创建?

Can any one tell me if its possible to create a stored procedure in oracle which accept array as an input parameter and how ?

推荐答案

是的.Oracle 将它们称为集合，您可以使用多种集合.

Yes. Oracle calls them collections and there's a variety of collections you can use.

使用 VARRAY 的简单数组示例.

A simple array example using a VARRAY.


DECLARE
  TYPE Str_Array IS VARRAY(4) OF VARCHAR2(50);
  v_array  Str_Array;

  PROCEDURE PROCESS_ARRAY(v_str_array  Str_Array)
  AS
  BEGIN
    FOR i IN v_str_array.first .. v_str_array.last LOOP
      DBMS_OUTPUT.PUT_LINE('Hello '||v_str_array(i));
    END LOOP;
  END;

BEGIN

  v_array := Str_Array('John','Paul','Ringo','George');

  PROCESS_ARRAY(v_array);

  -- can also pass unbound Str_Array
  PROCESS_ARRAY(Str_Array('John','Paul','Ringo','George'));

END;
