mybatis调用Oracle存储过程

1.创建Oracle存储过程完成库存加减操作，如果按equipType1和equipType2查询记录存在，则在原数量基础上进行增减；如果查询记录不存在，则新增一条记录。

存储过程创建如下：

CREATE OR REPLACE 
PROCEDURE "UPDATE_EQUIPMENT_STOCK" (P_EQUIP_TYPE1 IN NUMBER, P_EQUIP_TYPE2 IN NUMBER, P_NUM IN NUMBER, P_STATION_ID IN NUMBER, P_RESULT OUT NUMBER)
AS
STOCK_NUM NUMBER DEFAULT 0;
E_COUNT NUMBER DEFAULT 0;
BEGIN
SELECT COUNT(ID) INTO E_COUNT from EQUIPMENT_STOCK WHERE EQUIP_TYPE1=P_EQUIP_TYPE1 AND EQUIP_TYPE2=P_EQUIP_TYPE2;
IF (E_COUNT > 0) THEN
SELECT E_STOCK INTO STOCK_NUM from EQUIPMENT_STOCK WHERE EQUIP_TYPE1=P_EQUIP_TYPE1 AND EQUIP_TYPE2=P_EQUIP_TYPE2;
STOCK_NUM := STOCK_NUM + P_NUM;
UPDATE EQUIPMENT_STOCK SET E_STOCK=STOCK_NUM WHERE EQUIP_TYPE1=P_EQUIP_TYPE1 AND EQUIP_TYPE2=P_EQUIP_TYPE2;
--UPDATE
ELSE
STOCK_NUM:=P_NUM;
INSERT INTO EQUIPMENT_STOCK(ID,EQUIP_TYPE1,EQUIP_TYPE2,E_STOCK,STATION_ID) 
VALUES(SEQ_EQUIPMENT_STOCK.NEXTVAL,P_EQUIP_TYPE1,P_EQUIP_TYPE2,STOCK_NUM,P_STATION_ID);
--INSERT
END IF;
P_RESULT:=1;
END;

 mybatis调用

Mapper.xml

<select id="updateEquipmentStock" parameterType="java.util.Map" statementType="CALLABLE">
		{call UPDATE_EQUIPMENT_STOCK (#{equipType1,mode=IN,jdbcType=INTEGER},
			#{equipType2,mode=IN,jdbcType=INTEGER},
			#{pNum,mode=IN,jdbcType=INTEGER},
			#{stationId,mode=IN,jdbcType=INTEGER},#{p_result,mode=OUT,jdbcType=INTEGER})}
</select>

 Mapper.java

public Integer updateEquipmentStock(Map<String, Object> paramMap);

 Dao

public Integer updateEquipmentStock(Map<String, Object> paramMap) {
		// TODO Auto-generated method stub
		return equipmentStockMapper.updateEquipmentStock(paramMap);
	}

 Service

public Integer updateEquipmentStock(Long equipType1, Long equipType2, Integer pNum,
			Long stationId) {
		Map<String, Object> paramMap = new HashMap<String, Object>();
		paramMap.put("equipType1", equipType1);
		paramMap.put("equipType2", equipType2);
		paramMap.put("pNum", pNum);
		paramMap.put("stationId", stationId);
		paramMap.put("p_result", -1);
		equipmentStockDAO.updateEquipmentStock(paramMap);
		return (Integer)paramMap.get("p_result");
	}

 自己搜索资料编写，可用。

PS：pNum参数使用正负数完成库存的增减
