oracle-外连接left join的应用

需求

自助设备交易统计

输出（新增各业务的交易总额字段）：

我自己在报表工具birt中写的sql

以后用到left join 可以参考上面写的

此外，贴出在birt 的数据集脚本beforeOpen

var text="";
// 交易时间
text += " and  trans.P_REQ_DATE  between  ‘"+ reportContext.getParameterValue("startDate").toString().replaceAll("-","") +"‘ and ‘"+reportContext.getParameterValue("endDate").toString().replaceAll("-","") + "‘";

// 分行
var branchId=reportContext.getParameterValue("branchId"); 

if(branchId != null && branchId!="" && branchId!="null"){
    text += " and branch.INST_ID= " + branchId ;
}

// 支行
var subId=reportContext.getParameterValue("subId"); 

if(subId != null && subId!="" && subId!="null"){
    text += " and subbranch.INST_ID= " + subId ;
}

// 自助银行
var selfId=reportContext.getParameterValue("selfId"); 

if(selfId != null && selfId!="" && selfId!="null"){
    text += " and self.INST_ID= " + selfId;
}

// 终端号
var termId=reportContext.getParameterValue("termId"); 

if(termId != null && termId!="" && termId!="null"){
    text += " and trans.TERM_ID= " + termId ;
}

// 柜员号
var tellNo=reportContext.getParameterValue("tellNo"); 

if(tellNo != null && tellNo!="" && tellNo!="null"){
    text += " and trans.TELL_NO= " + tellNo ;
}

// 设备状态
var deviceState=reportContext.getParameterValue("deviceState"); 

if(deviceState != null && deviceState!="" && deviceState!="null"){
    text += " and device.DEVICE_STATE in ( " + deviceState + ")" ;
}

// queryText中只有一个 --XXXXYYYY--
var oldText=this.queryText.split("--XXXXYYYY--");
this.queryText=oldText[0]+text+oldText[1];
