I tried changing the MySQL query with ORDER BY for that specific column but that doesn't help? 回答1: You said "sort the values of a filter " -- do you mean you want to control the order of items in the filter panel? To do so, right click anywhere in the filter panel and choose Organize Filters. There you can use the Move Up/Move Down buttons to arrange to your preference. If instead you want to sort a Table visualization (a basic grid), you can just click on a column header for

If I call the orderBy method a second time, it replaces any previously specified orderings. I can pass two columns as the first parameter: ->orderBy('r.firstColumn, r.secondColumn', 'DESC'); But I cannot pass two ordering directions for the second parameter, so when I execute this query the first column is ordered in an ascending direction and the second

针对网上没有处理最后的排序图标问题。现提供完整的修改方案，如下： BootstrapTable.prototype.onSort = function (event) { var $this = event.type === "keypress" ? $(event.currentTarget) : $(event.currentTarget).parent(), $this_ = this.$header.find('th').eq($this.index()); this.$header.add(this.$header_).find('span.order').remove(); if (this.options.sortName === $this.data('field')) { this.options.sortOrder = this.options.sortOrder === 'asc' ? 'desc' : 'asc'; } else { //this.options.sortName = $this.data('field'); //解决展示字段和排序字段不一致问题 this.options.sortName = $this.data('sortName') ? $this.data('sortName') : $this.data('field'); this

上一篇文章我们测试一些order by查询和分页查询的一些基准性能,现在我们来分析一下条件索引查询的结果集的测试 现在我们继续进行一个 测试相同的表结构插入1亿条数据这次用到的是Innodb表引擎,表名有些变化,这里为甚要新建一个表的很重要元素是原来的那张表是每个uid=1来做的索引,这次uid是1...10不等的数每种1千万条记录 CREATE TABLE `ipdata` ( `id` int(11) NOT NULL AUTO_INCREMENT, `uid` int(8) NOT NULL DEFAULT '0', `ipaddress` varchar(50) NOT NULL, `source` varchar(255) DEFAULT NULL, `track` varchar(255) DEFAULT NULL, `entrance` varchar(255) DEFAULT NULL, `createdtime` datetime NOT NULL DEFAULT '0000-00-00 00:00:00', `createddate` date NOT NULL DEFAULT '0000-00-00', PRIMARY KEY (`id`), KEY `uid` (`uid`) } ENGINE=InnoDB AUTO_INCREMENT=100004857

MySQL is adding more tools to monitor its internals with every new release, but one thing it still lacks is a way to find out who is locking what, and therefore which transactions block which other ones. This is such a vital feature that I’m considering writing my own patch to the source! Still, it is possible, to a limited extent, to find out who’s locking resources. In this article I’ll explain how you can do that. innotop Introduction Here’s the situation: you are trying to update a table and every time you issue the query, it hangs until it times out and tells you the lock wait timeout was

前言： []包含的表示可选，|符号分开的表示可选其一。 本章内容 详解排序查询 详解limit limit存在的坑 分页查询中的坑 一、排序查询（order by） 　　select 字段名 from 表名 order by 字段 1 [asc|desc],字段 2 [asc|desc]; 　　 　　需要排序的字段跟在order by之后； 　　asc|desc表示排序的规则，asc：升序，desc：降序，默认为asc； 　　支持多个字段进行排序，多字段排序之间用逗号隔开。 　　单字段排序： select * from test2 order by a asc; 　　 多字段排序： select * from stu order by age desc,id asc; 　　 　　按别名排序： select age '年龄',id as '学号' from stu order by 年龄 asc,学号 desc; 　　 　　按函数排序： SELECT id 编号,birth 出生日期, year (birth) 出生年份,name 姓名 from student ORDER BY 出生年份 asc,id asc; 　　 　　where之后进行排序：select a.id 订单编号,a.price 订单金额 from t_order a where a.price>= 100
