java 实现往oracle存储过程中传递二维数组参数
一、SQL代码
create or replace type t_cableLine_point as object(
ID NUMBER(10),
CABLELINEID NUMBER(10),
ROADPOINTID NUMBER(10),
ORDERNUM NUMBER(10),
REMARK NUMBER(10)
)
CREATE OR REPLACE TYPE ARRAY_cableLine_point AS table OF t_cableLine_point
create table RSC_CABLELINE_POINT
(
ID NUMBER(10) not null,
CABLELINEID NUMBER(10) not null,
ROADPOINTID NUMBER(10) not null,
ORDERNUM NUMBER(10),
REMARK NUMBER(10)
)
create or replace procedure batch_cableline_point(i_object in ARRAY_cableLine_point) is
begin
insert into RSC_CABLELINE_POINT
(ID, CABLELINEID, ROADPOINTID, ORDERNUM, REMARK)
select ID, CABLELINEID, ROADPOINTID, ORDERNUM, REMARK
from the (select cast(i_object as ARRAY_cableLine_point) from dual);
end batch_cableline_point;
二、java测试代码
package com.common;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
public class Test {
public static void main(String[] args) {
Connection con = null;
PreparedStatement pstmt = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@127.0.0.1:1521:orcl";
con = DriverManager.getConnection(url, "test", "test");
String sql = "{call batch_cableline_point(?)}";
pstmt = con.prepareCall(sql);
Object[][] objects = new Object[10][5];
for (int i = 0; i < 10; i++) {
Object[] object = new Object[5];
object[0] = i;
object[1] = 158870593;
object[2] = 333;
object[3] = 444;
object[4] = 555;
objects[i] = object;
}
oracle.sql.ArrayDescriptor desc = oracle.sql.ArrayDescriptor
.createDescriptor("ARRAY_CABLELINE_POINT", con);
oracle.sql.ARRAY array = new oracle.sql.ARRAY(desc, con, objects);
pstmt.setArray(1, array);
pstmt.executeUpdate();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (pstmt != null)
pstmt.close();
if (con != null)
con.close();
} catch (Exception se) {
}
}
}
}
三、遇到的问题
1、java 调用oracle 数组出现??? 的乱码问题。
原因:缺少nls_charset12.jar包。
2、java如何读取plsql的对象数组,抛出异常:无效的名称模式。
原因:“ARRAY_CABLELINE_POINT”不能为小写。
