解决java.sql.SQLException: Value '0000-00-00' can not be represented as java.sql.Date

java.sql.SQLException: Value ‘0000-00-00’ can not be represented as java.sql.Date 异常的解决方法

查询数据时候遇到这个异常,stackoverflow上一条回答解决办法是通过给jdbc链接增加zeroDateTimeBehavior参数来解决。

jdbc:mysql://yourserver:3306/yourdatabase?zeroDateTimeBehavior=convertToNull

随后查阅了官方手册,给出的解释如下。

zeroDateTimeBehavior What should happen when the driver encounters
DATETIME values that are composed entirely of zeros (used by MySQL to
represent invalid dates)? Valid values are “exception”, “round” and
“convertToNull”. Default: exception Since version: 3.1.4
http://dev.mysql.com/doc/connector-j/5.1/en/connector-j-installing-upgrading-3-0-to-3-1.html

设置zeroDateTimeBehavior 属性,当遇到DATETIME值完全由0组成时,最终的有效值可以设置为,异常(exception)一个近似值(round),或将这个值转换为null(convertToNull)

随后近一步查阅手册,三个参数的详细解释如下。

exception (the default), which throws an SQLException with an SQLState
of S1009.
convertToNull, which returns NULL instead of the date.
round, which rounds the date to the nearest closest value which is
0001-01-01.
http://dev.mysql.com/doc/connector-j/5.1/en/connector-j-installing-upgrading-3-0-to-3-1.html

默认情况为exception,设置这个属性会抛出一个SQLException异常,其SQLSate码为S1009。这个状态码在写存储过程处理异常时也可以用到。

convertToNull,返回null来替代0000-00-00这样的日期。

round,将日期转换为0001-01-01。

因此,出现0000-00-00 属于一个无效日期,用convertToNull属性即可。
