CREATE OR REPLACE TYPE NEW_ADDRS_OBJ
AS OBJECT (newAddress1 varchar2(20),
newAddress2 varchar2(20),
city varchar2(20),
state varchar2(20),
zip number(20))

create or replace type NEW_ADDRS_OBJ_ARRAY as table of NEW_ADDRS_OBJ

CREATE OR REPLACE TYPE ACCOUNT_OBJ
AS OBJECT (fname varchar2(20),
newAddress NEW_ADDRS_OBJ_ARRAY)

create or replace type ACCOUNT_OBJ_ARRAY as table of ACCOUNT_OBJ

现在调用程序时

    CREATE OR REPLACE PROCEDURE INSERT_NEW_ADDRESS ( account_array in ACCOUNT_OBJ_ARRAY ) AS
tempaddres NEW_ADDRS_OBJ_ARRAY;
begin
  for i in 1..account_array.count loop
   tempaddres := NEW_ADDRS_OBJ_ARRAY();
   tempaddres := account_array(i).newAddress;
  for j in 1..tempaddres.count loop
    insert into TEST_ACCOUNT (ACCOUNT,NEWADDRESS1 ,NEWADDRESS2 ,CITY ,STATE ,ZIP )
       values(account_array(i).fname,
        tempaddres(j).newAddress1,
       tempaddres(j).newAddress2,
       tempaddres(j).city,
        tempaddres(j).state,
         tempaddres(j).zip);
  end loop;
  end loop;
end;

我可以使用 arraydescriptor 来传递父数组 ACCOUNT_OBJ_ARRAY ，但是如何从 Spring 过程调用中传递其中的数组（新地址对象的数组）？

有关如何在 java中绑定 SQL 对象的 SQL 嵌套表的示例，请参阅 SO 问题“如何在 java 中调用包含用户定义类型的 oracle 存储过程？ ”。这里的 SQL 对象本身也包含一个嵌套的对象表。方法类似（java中SQL数组由ARRAY对象绑定，SQL对象由STRUCT绑定）。

SQL> CREATE OR REPLACE PROCEDURE insert_new_address (
  2     account_array IN ACCOUNT_OBJ_ARRAY
  3     ) AS
  4     tempaddres NEW_ADDRS_OBJ_ARRAY;
  5  BEGIN
  6     FOR i IN 1 .. account_array.COUNT LOOP
  7        FOR j IN 1 .. account_array(i).newAddress.COUNT LOOP
  8           dbms_output.put_line(
  9              account_array(i).fname || ', ' || 
 10              account_array(i).newAddress(j).newAddress1 || ', ' || 
 11              account_array(i).newAddress(j).newAddress2 || ', ' || 
 12              account_array(i).newAddress(j).city || ', ' || 
 13              account_array(i).newAddress(j).state || ', ' || 
 14              account_array(i).newAddress(j).zip);
 15        END LOOP;
 16     END LOOP;
 17  END;

Procedure created

我将展示一个使用 Oracle java jvm 的演示：

Java created

现在我们调用java过程：

SQL> CREATE OR REPLACE
  2  PROCEDURE show_java_calling_plsql
  3  AS LANGUAGE JAVA
  4  NAME 'ArrayDemo.passArray()';
  5  /

Procedure created

SQL> exec show_java_calling_plsql

AcctName, address1, address2, city, state, 12345

PL/SQL procedure successfully completed
