Question

我想使用最新的Slick（3.1.1）分析遗留的mysql数据库（myisam引擎）。

但是，在该数据库上运行slick.codegen.SourceCodeGenerator会导致错误：

slick.SlickException: Could not parse default value Some(0000-00-00 00:00:00) for column foo.bar.baz of type java.sql.Timestamp, meta data: MColumn(MQName(foo.bar),baz,93,DATETIME,Some(19),None,10,Some(false),Some(),Some(0000-00-00 00:00:00),0,1,Some(false),None,None,Some(false))

相关表格（DDL代码）如下所示：

CREATE TABLE `bar` (`baz` DATETIME NOT NULL DEFAULT '0000-00-00 00:00:00') ENGINE=MyISAM

出了什么问题？怎么解决？

scala codegen无法处理datetime而不是默认的'0000-00-00 00:00:00'？
