Вызов Sql процедуры с весны DAO

Question

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 

Теперь при вызове процедуры

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; 

я могу сделать использование arraydescriptor передать родительский массив ACCOUNT_OBJ_ARRAY, но как передать массив внутри него (массив новых объектов адреса) из вызова процедуры Spring?

Answer 1

См. Вопрос SO «How to call oracle stored procedure which include user-defined type in java?» на примере того, как связать SQL-вложенную таблицу объекта SQL в java. Здесь сам объект SQL также содержит вложенную таблицу объекта. Метод аналогичен (массивы SQL привязаны объектом ARRAY в java, объекты SQL связаны STRUCT).

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 

Я покажу демо с помощью Oracle Java JVM:

SQL> CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "ArrayDemo" 
    2 as

11  public static void passArray() throws SQLException {

13  Connection conn = new OracleDriver().defaultConnection();

15  /*creation of NEW_ADDRS_OBJ*/ 
16  StructDescriptor addrObjDescriptor = 
17   StructDescriptor.createDescriptor("NEW_ADDRS_OBJ",conn);

Java created 

Теперь мы называем процедуру Java:

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
