23、Electron 连接 MSSQL

1、使用MSsql微软官方npm包，支持不够强大

npm install mssql@3.3.0 使用3X的版本4X的升级了 下面的用不了了。

下面是一个封装，复制至：https://blog.csdn.net/gzy11/article/details/52354441

var mssql = require('mssql');
var user = "sa",
    password = "123456",
    server = "127.0.0.1",
    database = "test";

var config = {
    user: user,
    password: password,
    server: server, // You can use 'localhost\\instance' to connect to named instance
    database: database,
    options: {
        encrypt: true // Use this if you're on Windows Azure
    },
    pool: {
        min: 0,
        idleTimeoutMillis: 3000
    }
};
 
var initConfig = function (user, password, server, database) {
    config = {
        user: user,
        password: password,
        server: server, // You can use 'localhost\\instance' to connect to named instance
        database: database,
        options: {
            encrypt: true // Use this if you're on Windows Azure
        },
        pool: {
            min: 0,
            idleTimeoutMillis: 3000
        }

var restoreDefaults = function () {
    config = {

            min: 0,
            idleTimeoutMillis: 3000
        }
    };
};
 

var querySql = function (sql, params, callBack) {
    var connection = new mssql.Connection(config, function (err) {
        var ps = new mssql.PreparedStatement(connection);
        if (params != "") {
            for (var index in params) {
                if (typeof params[index] == "number") {

                    ps.input(index, mssql.NVarChar);
                }
            }
        }
        ps.prepare(sql, function (err) {
            if (err)
                console.log(err);
            ps.execute(params, function (err, recordset) {
                callBack(err, recordset);
                ps.unprepare(function (err) {
                    if (err)
                        console.log(err);
                });
            });
        });
    });
    restoreDefaults();
};
 
//querySql("select id as roleId,roleName from dbo.role","",function(err,recordset){
//   console.dir(recordset);
//});
