我正在使用Grails 2.2.4和db-migrate插件1.3.5。我的数据库是mysql。
与数据库同步的现有模型是:
class User {
String description
}
Hibernate用它在mysql中制作了一个varchar(255)。我需要一个较长的文本列，所以我做了:
class User {
String description
static mapping = {
description type: 'text'
}
}
然后我运行了dbm-gorm-diff change-column.groovy -add
并得到以下错误。我该怎么办？
| Starting dbm-gorm-diff
| Error org.hibernate.MappingException: No Dialect mapping for JDBC type: 7
| Error at grails.plugin.databasemigration.GormDiff.areEquivalent(GormDiff.groovy:146)

请您参考如下方法:
正如@raxith所评论的那样，使用dbm从1.3.2升级到1.3.8到grails 2.2.5对我有用
