行转列之后的datagrid的保存的相关文章

Easyui Datagrid 修改显示行号列宽度

EasyUI中Datagrid的第一列显示行号,可是如果数据量大的的时候,显示行号的那一列数据会显示不完全的. 可以通过修改Datagrid的样式来解决这个问题,在样式中加入下面这个样式,就可以自己修改显示行号列的宽度了 .datagrid-header-rownumber,.datagrid-cell-rownumber{ width:40px; }

一.行转列在有些应用场景中,如学生成绩.学生所有科目的成绩都保存到一张表里面,当我们需要以列表的形式显示出学生所对应的每一科目的成绩的时候,需要使用到行转列. 示例 1 -- 学生成绩表 2 create table grade ( 3 id varchar2(64) not null, 4 name varchar2(20) not null, 5 course varchar2(100) not null, 6 score number(3) not null, 7 primary key

PIVOT就是行转列，UNPIVOT就是列传行

PIVOT通过将表达式某一列中的唯一值转换为输出中的多个列来旋转表值表达式,并在必要时对最终输出中所需的任何其余列值执行聚合.UNPIVOT与PIVOT执行相反的操作,将表值表达式的列转换为列值. 通俗简单的说:PIVOT就是行转列,UNPIVOT就是列传行一.PIVOT实例 1. 建表建立一个销售情况表,其中,year字段表示年份,quarter字段表示季度,amount字段表示销售额.quarter字段分别用Q1, Q2, Q3, Q4表示一.二.三.四季度. SQL 代码复制 C
