需求描述

今天遇到一个小的需求,就是要根据Excel中的若干列数据生成多条SQL插入脚本,类似于下面input.txt文件这样:

2   24  0   1   1   a04005  .3

每行数据格式都是一样的,分别代表protocol, slave, number, ptype, pid,name, format,每个字段以'\t'制表符为分隔符。
上面的input.txt是我从Excel中粘贴复制过来的,本想复制到Editplus进行处理,然后生成类似于每行

INSERT INTO tb_param(protocol, slave, number, ptype, pid, name, format)
 VALUES(2, 24, 0, 1, 1, 'a04005', '.3');

这样的SQL插入脚本。
直接用C++也可以写,对于nodejs读写文件不是很熟练,于是上网找资料,得到下面的解决方案:

var fs = require('fs');
var readline = require('readline');
var os = require('os'); 

// Node.js readline 逐行读取、写入文件内容的示例
// https://www.jb51.net/article/135706.htm
// nodejs读取文件、按行读取
// https://blog.csdn.net/weixin_42171955/article/details/100156212

var strInputFileName = './input.txt';
var strOutputFileName = 'output.txt';

var fRead = fs.createReadStream(strInputFileName); 
var fWrite = fs.createWriteStream(strOutputFileName); 
  
fRead.on('end', ()=>{ 
 console.log('end'); 
}); 
  
var objReadline = readline.createInterface({ 
 input: fRead, 
 output: fWrite, 
 terminal: false
}); 

objReadline.on('line', (strLine)=>{ 
 // 获取某一行的数据,数据以\t分割,例如:24  0   1   1   a04005  .2
 var strArr = strLine.split('\t');
 let protocol = strArr[0];
 let slave = strArr[1];
 let number = strArr[2];
 let ptype = strArr[3];
 let pid = strArr[4];
 let name = strArr[5];
 let format = strArr[6];

// 由于readline::output是先写入后调用的on('line')事件, 
// 所以已经读取文件完毕时就不需要再写行号了... 
// INSERT INTO tb_param(protocol, slave, number, ptype, pid, name, format)
// VALUES (2, 29, 0, 1, 2, 'a06011', '.3');
let strTemp = `INSERT INTO tb_param(protocol, slave, number, ptype, pid, name, format)\n `;
strTemp += `VALUES(${protocol}, ${slave}, ${number}, ${ptype}, ${pid}, '${name}', '${format}');\n`;
fWrite.write(strTemp); 
}); 
 
 
objReadline.on('close', ()=>{ 
 console.log('readline close...'); 
}); 

运行代码,在当前项目目录下得到output.txt文件如下:

INSERT INTO tb_param(protocol, slave, number, ptype, pid, name, format)
