今天做项目的时候,遇到个小小的问题,在数据库中查询的时候,要用String类型的ID进行一下排序!(注:ID字段为 varchar 类型) 解决的方法: 如: SELECT * FROM Student WHERE 1 = 1 ORDER BY -ID DESC 或者: SELECT * FROM Student WHERE 1 = 1 ORDER BY (ID + 1) mysql时间格式化,按时间段查询MYSQL语句 2011-04-15 09:01:08| 分类: MySQL |
sql server 分页按时间排序 select * from (select<include refid="Base_Column_List"/>, ROW_NUMBER() OVER(Order by check_date )-1 AS RowNumber from user <include refid="pageListQueryCondition"/> ) c where RowNumber BETWEEN (#{paginati
mysql 自定义排序顺序 实例如:在sql语句中加入ORDER BY FIELD(status,3,4,0,2,1)语句可定义排序顺序 SELECT tsdvoucher0_.VOUCHER_ID AS VOUCHER1_0_, tsdvoucher0_.COMMENT_DEVICE_TYPE AS COMMENT2_0_, tsdvoucher0_.COMMENT_ID AS COMMENT3_0_, tsdvoucher0_.COMMENT_PERSON_NO AS COMMENT4_0_
Mysql 时间格式默认插入值为空时,会以'0000-00-00 00:00:00'填充,这时如果select时会抛出SQLExecption如下: java.sql.SQLException: Value '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp 解决方法如下: 方法一:jdbc的url加zeroDateTimeBehavior参数: datasource.url=jdbc:mysql://localh
