BEGIN#前提:指定字符串长度为8字符定长#逻辑:循环8次,比对2个字符串相同索引位置下的数值大小,并取结果最大值.#示例:merge1(输入参数source1,输入参数source2,输出结果result)#注意:输入参数必须是8位字符串 set @cindex=1; set result=''; WHILE @cindex<9 DO set @temp1=SUBSTR(source1,@cindex,1)+0; set @temp2=SUBST…
SELECT pid, GROUP_CONCAT(field ORDER BY coder desc) 'msg'from product_field GROUP BY pid 分组加排序 group_concat()函数总结 group_concat(),手册上说明:该函数返回带有来自一个组的连接的非NULL值的字符串结果.比较抽象,难以理解. 通俗点理解,其实是这样的:group_concat()会计算哪些行属于同一组,将属于同一组的列显示出来.要返回哪些列,由函 数参数…
通常我们在ListView中展示一列同类数据,例如城市名称.不过可以对ListView的DataTemplate稍作修改,让其显示层叠信息.例如:需要在ListView中显示省份和省份对应的城市名称.首先准备基础类, City类: public class City : ViewModeBase { private string _name; public string Name { get { return _name; } set { if (_name != value) { _name…
最近工作遇到如下数据:需要合并后只剩下两行的数据,普通的group by 是不能实现的.(如图) 利用如下SQL代码,即可实现需求(如图): 利用 stuff 函数实现分拆合并操作 select TeacherName,TrainingCenterName=stuff ( (select ','+TrainingCenterName from @tmp a where a.TeacherName=b.TeacherName for xml path('')),1,1,'' ) from @tmp…
