oracle使用存储过程返回游标实现报表查询

最近在oracle中通过存储过程实现一个报表查询，查询涉及到数据计算这里使用了临时表和存储过程实现输出查询，java接受游标变量返回结果集

第一步、创建统计使用的临时表

CREATE GLOBAL TEMPORARY TABLE T_TMP_REPORT_YFCHSLZZ(
        DRUG_ID NUMBER(22) not null, --药品id
        MAX_UNIT_ID NUMBER(22) not null, --最大包装id
        DRUG_UNIT_ID NUMBER(22), --药房包装单位id
        RECORD_FLAG NUMBER(4) not null, --记录类型0药品记录,1期初,2入库,3盘点盈亏,4出库,5报损
        PRE_QUANTITY NUMBER(18,4) default 0 not null, --期初发生数量
        QUANTITY NUMBER(18,4) default 0 not null, --发生数量
        RELATION NUMBER(12) --业务单据包装单位换算比
        ) ON COMMIT PRESERVE ROWS
/
create index IDX_TMP_REPORT_YFCHSLZZ_DF
    on T_TMP_REPORT_YFCHSLZZ (DRUG_ID,RECORD_FLAG);
/

第二步、创建存储过程，过程代码省略部分统计语句

create or replace PROCEDURE P_RPT_YFCHSLZZ (
--药房统计存货数量总账用过程 liuyc 20230317
    v_typeIds IN VARCHAR2, --药品类别id逗号隔开字符串
    v_drugId IN VARCHAR2, --药品id
    v_deptId IN INT, --药房id
    v_hosId IN INT, --医院id
    v_includeDisable IN INT, --是否包含停用药品0否1是
    v_beginDate IN DATE, --统计起日期
    v_endDate IN DATE, --统计止日期
    v_result out SYS_REFCURSOR --返回结果列表
)

    v_sql varchar2(2000); --动态执行的语句
    v_expType varchar2(500); --药品类别查询条件

    delete from T_TMP_REPORT_YFCHSLZZ;

    v_expType:='';
    if length(nvl(v_typeIds,''))>0 then
        v_expType:=' and a.DRUG_TYPE_ID in ('||v_typeIds||')';
    end if;
    v_expDrug:='';
    if length(nvl(v_drugId,''))>0 then
        v_expDrug:=' and a.ID='||v_drugId;
    end if;
    v_expDis:=' a.STATUS=''1''';
    if v_includeDisable=1 then

    end if;
    v_sql:='insert into T_TMP_REPORT_YFCHSLZZ(DRUG_ID,MAX_UNIT_ID,DRUG_UNIT_ID,RECORD_FLAG)

第三步、java代码Mapper文件调用存储过程，返回实体代码此处不再展示，方法声明：void listInOutQuantityGL(Map<String,Object> param);

<resultMap id="InOutQuantityGLResultMap" type="cn.net.sunshine.hisManagement.drugStoreReport.bean.InOutQuantityGL">
        <id column="ID" property="id"/>
        <result column="DRUG_CODE" jdbcType="VARCHAR" property="drugCode"/>
        <result column="DRUG_NAME" jdbcType="VARCHAR" property="drugName"/>
        <result column="SPEC" jdbcType="VARCHAR" property="spec"/>
        <result column="DRUG_UNIT_ID" jdbcType="DECIMAL" property="drugUnitId"/>
        <result column="UNIT_NAME" jdbcType="VARCHAR" property="unitName"/>
        <result column="DRUG_TYPE_ID" jdbcType="DECIMAL" property="drugTypeId"/>
        <result column="DRUG_TYPE_NAME" jdbcType="VARCHAR" property="typeName"/>
        <result column="PRE_QUANTITY" jdbcType="DECIMAL" property="preQuantity"/>
        <result column="IN_QUANTITY" jdbcType="DECIMAL" property="inQuantity"/>
        <result column="OUT_QUANTITY" jdbcType="DECIMAL" property="outQuantity"/>
        <result column="INV_QUANTITY" jdbcType="DECIMAL" property="invQuantity"/>
        <result column="LOSS_QUANTITY" jdbcType="DECIMAL" property="lossQuantity"/>
        <result column="FINAL_QUANTITY" jdbcType="DECIMAL" property="finalQuantity"/>
    </resultMap>

    <!--收发存数量汇总查询-->
    <select id="listInOutQuantityGL" parameterType="java.util.Map" statementType="CALLABLE">
        call P_RPT_YFCHSLZZ(
        #{v_typeIds,mode=IN,jdbcType=VARCHAR},
        #{v_drugId,mode=IN,jdbcType=VARCHAR},
        #{v_deptId,mode=IN,jdbcType=DECIMAL},
        #{v_hosId,mode=IN,jdbcType=DECIMAL},
        #{v_disableDrug,mode=IN,jdbcType=DECIMAL},
        #{v_beginDate,mode=IN,jdbcType=DATE},
        #{v_endDate,mode=IN,jdbcType=DATE},
        #{v_result,jdbcType=CURSOR,mode=OUT,javaType=ResultSet, resultMap=InOutQuantityGLResultMap}
        )
    </select>

第四步、java中Service层调用代码，这样就可以获取存储过程返回的结果集。

@Override
    public List<InOutQuantityGL> listInOutQuantityGL(InOutQuantityGLQuery queryParam) {
        Map<String,Object> param =new HashMap<String, Object>();
        param.put("v_drugId",queryParam.getDrugId()==null?"":queryParam.getDrugId().toString());
        if (queryParam.getDrugType()==null || queryParam.getDrugType().length<=0){
            param.put("v_typeIds","");
        }
        else{
            String typeIds = StringUtils.join(queryParam.getDrugType(),",");
            param.put("v_typeIds",typeIds);
        }
        param.put("v_deptId",queryParam.getDeptId());
        param.put("v_hosId",queryParam.getHosId());
        param.put("v_disableDrug",queryParam.getIncludeDisable()?1:0);
        param.put("v_beginDate",queryParam.getBeginDate());
        param.put("v_endDate",queryParam.getEndDate());
        drugStoreReportMapper.listInOutQuantityGL(param);
        List<InOutQuantityGL> list = (List<InOutQuantityGL>)param.get("v_result");
        Integer rowNo = 1;
        for (InOutQuantityGL item:list){
            item.setRowNo(rowNo);
            rowNo++;
        }
        return list;
    }
