Question

我通过数据库迁移插件0.2.1使用Grails 1.3.7 + MySQL 5.5 + Liquibase。

当我在开发环境中时，我将Hibernate配置为使用“create-drop”，但在我的QA环境中，我想使用liquibase来创建我的表。这是我的环境配置：

environments {
    development {
        dataSource {
            configClass = GrailsAnnotationConfiguration.class
            pooled = false
            driverClassName = "com.mysql.jdbc.Driver"
            username = "root"
            password =  ""
            dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
            dbCreate = "create-drop"
            url = "jdbc:mysql://localhost/dripita_dev"      
        }
    }
    localQa {
        dataSource {
            configClass=GrailsAnnotationConfiguration.class
            pooled=false
            driverClassName="com.mysql.jdbc.Driver"
            username="root"
            password=""
            dialect="org.hibernate.dialect.MySQL5InnoDBDialect"
            url="jdbc:mysql://localhost/dripita_localqa"        
        }
    }
 ...
}

当我以开发模式启动应用程序时，数据库表可以正常创建。我执行以下操作来创建更改日志：

$ grails dbm-generate-gorm-changelog changelog.groovy

看起来像这样：

changeSet(author: "javidjamae (generated)", id: "1309959832163-2") {
    createTable(tableName: "payment") {
        column(autoIncrement: "true", name: "id", type: "bigint") {
            constraints(nullable: "false", primaryKey: "true", primaryKeyName: "paymentPK")
        }

        column(name: "version", type: "bigint") {
            constraints(nullable: "false")
        }

        column(name: "buyer_id", type: "bigint") {
            constraints(nullable: "false")
        }

        column(name: "buyer_information_id", type: "bigint")

        column(name: "currency", type: "varchar(255)") {
            constraints(nullable: "false")
        }

        column(name: "discount_cart_amount", type: "decimal(19,2)") {
            constraints(nullable: "false")
        }

        column(name: "paypal_transaction_id", type: "varchar(255)")

        column(name: "status", type: "varchar(9)") {
            constraints(nullable: "false")
        }

        column(name: "tax", type: "double precision(19)") {
            constraints(nullable: "false")
        }

        column(name: "transaction_id", type: "varchar(255)")
    }
}

然后我尝试从更改日志中创建表：

$ grails -Dgrails.env=localQa dbm-update

但是，当我运行dbm-update时，我收到以下错误：

当我在MySQL中复制/粘贴create语句时，我得到了同样的错误。我甚至关闭了ENGINE = InnoDB，看看是否有所作为，但事实并非如此。有什么想法吗？

仅供参考：我在Mac上使用HomeBrew安装了MySQL。

我的猜测是你的QA数据库不知道数据类型double precision(19)是什么尝试将其更改为double precision。

如果失败，请考虑使用其他数据类型：doc表示双精度是“非标准变体”
