oracle通过存储过程上传list保存功能
作者：丁三寿
这篇文章主要介绍了oracle通过存储过程上传list保存功能,本文通过实例代码给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
一、创建oracle 需要保存的数据类型type和存储过程produce
create TYPE "AL01TYPE" as object
(
-- 描述 : 档案批量转出
-- 作者 : dt
-- 时间 : 2021-05-10
-- 版本 ：dev-1.0.1
aac003 NVARCHAR2(100),
aac002 NVARCHAR2(50),
aat001 NVARCHAR2(50),
aat002 NVARCHAR2(50),
aat013 NVARCHAR2(20),
aae011 NVARCHAR2(20),
aae036 NVARCHAR2(20),
aah002 NVARCHAR2(100)
);
create type AL01TYPELIST as table of AL01TYPE;
-- auto-generated definition
create PROCEDURE SP_HFSZHDA_DOUPLOADAL01(LIST IN AL01TYPELIST,
po_message OUT VARCHAR) IS

--版本：dev-1.0.1
v_object AL01TYPE;
le_error EXCEPTION;
P_renum number(20);
v_aah002 VARCHAR(100);
ls_count number;
ls_aaf025 VARCHAR(50);
BEGIN
P_renum := 0; --初始化
FOR I IN 1 .. LIST.count LOOP
P_renum := 1 + P_renum;
v_object := LIST(I);
select replace(utl_raw.cast_to_varchar2(utl_raw.cast_to_raw(v_object.aah002)),unistr('\0000')) into v_aah002 from dual;
begin
Select count(0) into ls_count from az03 where aat001 = v_object.aat001 AND aat012 = '1';
if ls_count=0 then
po_message := '号：'||v_object.aat001||' 状态异常请核对后再上传！';
RAISE le_error;
end if;
Select count(0) into ls_count From AL01 where aaj022='1' and aat001=v_object.aat001 and aah002=v_aah002;
if ls_count =0 then
-- 开始插入信息
select SQ_AAF025.nextval into ls_aaf025 from dual;
insert into AL01(
aaf025,
aat012,
aat001,

'excel上传数据',
v_object.aae011,
v_object.aae036,
v_aah002
);
end if;
IF P_renum >1000 THEN
commit;
P_renum:=0;
END IF;
po_message :='ok';
EXCEPTION
WHEN le_error THEN
NULL;
WHEN OTHERS THEN
ROLLBACK;
po_message := '上传失败' || SQLCODE || SQLERRM;
end;
END LOOP;
COMMIT;
END SP_HFSZHDA_DOUPLOADAL01;
二、通过过程上传list

if (objlist != null && objlist.size() > 0) {
StructDescriptor structdesc = new StructDescriptor(OracleObj, connection);
STRUCT[] structs = new STRUCT[objlist.size()];
for (int i = 0; i < objlist.size(); i++) {
Object[] result= (Object[]) objlist.get(i);
structs[i] = new STRUCT(structdesc, connection, result);
}
ArrayDescriptor desc = ArrayDescriptor.createDescriptor(Oraclelist,connection);
array = new ARRAY(desc, connection, structs);
}
return array;
}
}
List<Object[]> arrList = new ArrayList<>();
//解析数据datamap

}
//开始调用过程
long startTime=System.currentTimeMillis();
Connection connection = null;
CallableStatement sqlres = null;
String sql = "call SP_HFSZHDA_DOUPLOADAL01(?,?)";
String msg = "";
try {
connection = dataSource.getConnection();
ARRAY paramArr = OracleUtil.getArray(connection,"AL01TYPE","AL01TYPELIST",arrList);

long endTime=System.currentTimeMillis()-startTime;
System.out.println("上传后获取的返回参数为："+msg+"||耗时："+endTime/1000+"秒");
} catch (SQLException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}finally {
try {
if (sqlres != null) {
sqlres.close();
}
if (connection != null) {

}
} catch (SQLException e) {
e.printStackTrace();
}
if (!"ok".equals(msg)){
throw new BusinessException("上传失败！"+msg);
}
}
