我正在使用 PHP 和后端 ClickHouse 数据库开发站点。当我使用 like 查询时，它不支持区分大小写的单词。

select id,comments from discussion where  comments LIKE "%Data not reflect%";

有没有办法搜索不区分大小写的单词？

任何人都可以帮助我,如何在节点js中使用node-ssh模块断开ssh连接.另外如何处理错误.

我的代码是

 driver = require('node-ssh');

    ssh = new driver({
              host: '192.168.*.*',
              username: 'user',
              password: 'password',
              privateKey : require('fs').readFileSync('/tmp/my_key')
            });

    ssh.connect().then(function() {
           /*
       some code
        */

            },function(error) {
                console.log(error);

    });

请帮忙.

将 ssh 服务器与节点 js 中的身份文件连接时出现以下错误

错误：无法读取私钥文件

my code:

    driver = require('node-ssh');

    ssh = new driver({
              host: '192.168.*.*',
              username: 'user',
              password: 'password',
              privateKey : require('fs').readFileSync('/tmp/my_key')
            });

    ssh.connect().then(function() {
           /*
       some code
        */

            },function(error) {
                console.log(error);

            });

But if i connect from my linux machine, it is connected.

ssh -i /tmp/my_key  user@192.168.*.*

Please give any solution for this.

我想使用节点js获取mongodb服务器的slavestatus。这是代码。

var Db = require('mongodb').Db, Server = require('mongodb').Server;
        var db = new Db('admin', new Server(conf.host, conf.port));
        db.open(function(err, db1) {
            var adminDb = db1.admin();
             adminDb.command({ "status": 1 },function(err,result) {
                  console.log("output="+result);
            });
    });

但我收到错误。

错误=MongoError：没有这样的命令：'状态'，错误的cmd：'{状态：1}'

我想在CentOS Linux系统中通过PHP连接MSSQl服务器。但是低于错误，

Fatal error: Call to undefined function mssql_connect() in /var/www/h.....

 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.
