开发中经常遇到把多个id拼接在一起符号隔开传入数据库,那拆分呢就是个大事 SELECT nPushID INTO #temp FROM Table1 ), nCoulmn) SELECT * FROM #temp 这里的列针对的是int 型,所以要转换. 针对订单那种订单主从表,从表多个的名称拼接在一起的 --实例1 分割符在前 select isnull ((select '@'+ CommodityName from OrderInfo where OrderInfo.orderid =Or

树形表结构: id parentID isDel 1 0 0 2 1 0 3 1 1 4 2 0 5 2 0 一)根据父级ID查找所有子级ID,并将所有ID用逗号隔开返回 ID=,需要返回的结果(条件为isDel=0,含本身ID): 1,2,4,5 SQL语句如下: with cteCopy as ( union all ) , , '') AS ids 返回 ids 1,2,4,5 二)根据子级ID查找所有父级ID,并将所有ID用逗号隔开返回 ID=,需要返回的结果(条件为isDel=0,不含

用hibernate进行映射查询时,出现Caused by: java.sql.SQLException: Column 'id' not found 异常,检查数据库表及映射都有id且已经正确映射,google后发现原因为: Your query doesn't return a field named id即查询sql中没有查询出主键id列,但返回结果集中用到,故出现异常特此记录. 详细解答见下: http://stackoverflow.com/questions/34164411/cau

例如:有表MO_Cook,字段:FoodRoom,name   有如下数据: 要求:将FoodRoom中值相同的字段合并成一行,并将name的值用逗号隔开. 需要用到:STUFF函数. 查询语句如下: select FoodRoom, stuff((select ','+name from MO_Cook where c.FoodRoom=FoodRoom ,,'') as CookNames from MO_Cook c group by c.FoodRoom 查询结果如下: STUFF (

什么是自增列 在SQL Server中可以将Id列设为自增.即无需为Id指定值,由SQL Server自动给该列赋值,每新增一列Id的值加一,初始值为1. 需要注意的是即使将原先添加的所有数据都删除,然后新增数据.此时记录的Id依然不会从1开始,而是原先的最大值加1. 自增列的取值范围 一般在定义自增列时,都会指定其数据类型为int类型.而且也只有int类型及其相关数据类型的列可以指定为自增列. 下面是自增列可以使用的数据类型: (,,,,,,) 到 (,,,,,,) 字节 (,,,) 到 (,
