駱駝sql存儲的java，不能輸入數組作為oracle存儲過程的輸入參數

Question

如何使用駱駝路線輸入數組作為oracle存儲過程的輸入參數

• 數據庫：Oracle XE 11G，表：hr.DEPARTMENTS示例pl / sql，在數組{“ Administration”，“ Marketing”}中發送departments_name期望得到department_id的總和。

1）創建一個嵌套表類型：

create or replace TYPE "NAME_TYPE" IS TABLE OF VARCHAR2(4000)

2）創建一個存儲過程：

create or replace PROCEDURE    test_departments_array
  (  p_dep_names   IN NAME_TYPE,
    r_dep_id_sum OUT INTEGER )
AS
r_dep_id INTEGER;
BEGIN
r_dep_id_sum :=0;
FOR i IN p_dep_names.first .. p_dep_names.last 
LOOP
    select d.department_id into r_dep_id 
    from hr.departments d where d.department_name=p_dep_names(i);

    r_dep_id_sum := r_dep_id_sum + r_dep_id;
 DBMS_OUTPUT.put_line('input:'||p_dep_names(i));

END LOOP;

END test_departments_array;

3）客戶代碼：（證明程序有效）

declare
in_values NAME_TYPE := NAME_TYPE('Administration','Marketing');
out_value INTEGER;
begin

hr.test_departments_array(
  p_dep_names => in_values,r_dep_id_sum => out_value);

DBMS_OUTPUT.put_line('output:'||out_value);

end;

4）輸出：

輸入：管理

輸入：市場營銷

輸出：30

5）Java代碼：

package test.camel.javadsl;

import java.sql.Array;

import javax.sql.DataSource;

import org.apache.camel.builder.RouteBuilder;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Component;

import oracle.jdbc.driver.OracleConnection;


@Component

public class JavaDslRouteBuilder extends RouteBuilder {

@Autowired

DataSource dataSource;

@Override

public void configure() throws Exception {

final OracleConnection conn= (OracleConnection)dataSource.getConnection();

String[] values = {"Administration0","Marketing"};

Array array = conn.createOracleArray("NAME_TYPE", values);;

from("stream:in?promptMessage=Enter to start:")

.setHeader("p_dep_names",simple( "${array}"))

.to("sql-stored:QUERY_DEPARTMENTS_ARRAY(ARRAY ${header.p_dep_names})");

}

}

6）錯誤信息：

Answer 1

我必須進行以下更改才能使其正常運行。 感謝Bedla。

ARRAY array = (ARRAY) conn.createOracleArray("NAME_TYPE", values);

from("timer://runOnce?repeatCount=1&delay=1000")
    .setHeader("p_dep_names", constant(array)) // Used constant to pass array reference instead of simple
    .to("sql-stored:TEST_DEPARTMENTS_ARRAY(ARRAY 'NAME_TYPE' ${header.p_dep_names}, OUT INTEGER r_dep_id_sum )") // Used 'NAME_TYPE'
    .to("log:stream");
