在表插入

问题描述

我需要将数据从json文件加载到名为Locality的MysqL数据库表中。下面的代码返回一个MysqL语法错误。适用于aurora MysqL Serverless的MysqL版本5.7.30。我正在使用aws-sdk，导入所有库，创建RDS实例。但是由于某种原因，它会返回sql语法错误。

如果我能看到rds.batchExecuteStatement作为sql产生的内容，这也将有所帮助。我已经尝试过了，但是找不到sql语句是什么。 （帮助？）

我已从以下AWS文档中将python转换为javascript Using the Data API for RDS Serverless

快速链接查看batchExecuteStatement函数： RDS.batchExecuteStatement Docs

const loadLocalities = () => {

    // Read data from the json file
    const data = require('./GeoDyDB.json')

    // Extract the data from the JSON into a format RDSDataService.batchExecuteStatement expects for the parameterSets argument
    const localityParameterSets = data.map(function(location){
        return [
            {name: 'code',value: {stringValue: generate_locality_sort_key(location)}},{name: 'synonyms',value: {stringValue: location.formatted_address}},{name: 'country',value: {stringValue: location.Country}},{name: 'state',value: {stringValue: location.State}},{name: 'city',value: {stringValue: location.City}},{name: 'zone',value: {stringValue: location.Zone}},{name: 'ward',value: {stringValue: location.Ward}},{name: 'colony',value: {stringValue: location.Colony}},{name: 'pincode',value: {isNull: true}},{name: 'lat',value: {stringValue: location.Lat.toString()}},{name: 'lng',value: {stringValue: location.Lng.toString()}},{name: 'geohash',{name: 'obj',value: {stringValue: location.Country}}
            /* more columns */
        ]
    })




    // Create the sql statement to run for all the items to insert as per AWS Docs linked above
    sqlStatement = `INSERT INTO Locality (code,synonyms,country,state,city,zone,ward,colony,pincode,lat,lng,geohash,obj) VALUES (:code,:synonyms,:country,:state,:city,:zone,:ward,:colony,:pincode,:lat,:lng,:geohash,:obj);`


    var params = {
        resourceArn: 'arn:aws:rds:...xxx',/* required */
        secretArn: 'arn:aws:secretsmanager:...xxx',/* required */
        sql: sqlStatement,/* required */
        database: 'mydb',parameterSets: localityParameterSets
    };
    rds.batchExecuteStatement(params,function(err,data) {
    if (err) console.log(err,err.stack); // an error occurred
    else     console.log(data);           // successful response
    });
}

这将返回以下错误

我运行了我希望SQL查询在AWS Query编辑器中执行的操作，以检查是否存在语法错误，但是此查询成功运行。

INSERT INTO Locality (code,geohash) VALUES 
('loc/ncr-newdelhi#patparganj@acharyaniketan',New Delhi,Delhi 110091','India','New Delhi','Shahadra South','Patparganj','Acharya Niketan','undefined','28.6081393','77.29474669999999','India');

起初我以为可能是保留关键字“未定义”，但事实并非如此。我觉得我缺少一些明显的东西，因为它应该是语法错误，但我无法发现它。成为我的StackOverflow天使。

谢谢

解决方法

您忘记向sqlStatement 函数提供SQL查询（rds.batchExecuteStatement），您为其提供了参数，但是没有SQL代码可将其应用于。

我遇到了同样的问题。调试了好几个小时才发现你的sql语句末尾不能包含分号...
