我正在使用带react的流星制作网络应用程序，在我的LedgerMaster.jsx中是

   import React, { Component } from 'react';
   import { createContainer } from 'meteor/react-meteor-data';
   import { LedgerMasterApi } from '../../../api/ledgerMaster';
   import  LedgerMasterForm  from './LedgerMasterForm';
   import  LedgerMasterDiplay  from './LedgerMasterDiplay';
    class LedgerMaster extends Component {
    render(){
    return(
        <div>
          <LedgerMasterForm />
          <LedgerMasterDiplay ledgeres={this.props.ledgeres}  />
        </div>
       );
      }
    }
 export default createContainer(() => {
  return {
     ledgeres: LedgerMasterApi.find({}).fetch(),
    };
 }, LedgerMaster);

所以问题是我必须在用于插入的LedgerMasterForm和用于提取数据的LedgerAsterDiplay中定义我的import { LedgerMasterApi } from '../../../api/ledgerMaster';我不确定。你想干什么就干什么。

使用此查询。

SELECT category.catnap,sub_category.subcatname  FROM category
INNER JOIN sub_category ON TRIM(category.canid) = TRIM(sub_category.canid)  ORDER BY category.catnap ASC

使用此代码

while(rs.next()){
       out.println(rs.getString("catnap")+"."+rs.getString("subcatname"));
}

    rs=stat.executeQuery("select count(catname) as numRows, catname from category group by catname");
    while(rs.next()){
        String cat="";int count=0;
       int catrow=rs.getInt("numRows");
       for (int j=1;j<=catrow.length;j++){
           count=0;
           cat=rs.getString("catname");
           system.out.println(cat);
           rs1=stat.executeQuery("SELECT sub.subcatname from sub_category sub where sub.catid="+'cat'+);
           while(rs1.next()){
               system.out.println(rs1.getString("subcategory"));
               count++;
           }
       }
}
