我有一个针对客户的域类。我最近不得不更改为域类，因为我们正在收集帐单地址和送货地址，但只记录了一个邮政编码值。所以我想一个简单的解决方法。将 zipcode 更改为 billzipcode，然后为 shipzipcode 创建一个新字段。我运行 dbm-gorm-diff 来创建更改日志，然后运行 ​​dbm-update 来执行我所做的更改。到目前为止，一切都很顺利。但随后我去调试应用程序以查看对数据源的更改是否正常。但是，现在当我尝试保存新的客户记录时，会出现以下错误：

    NULL not allowed for column "ZIPCODE"; SQL statement:
insert into customer (id, version, billaddr, billcity, billstate, billzipcode, cell, contact, country_id, custcode, custname, date_created, email, fax, last_updated, organization, phone, shipaddr, shipasbill, shipcity, shipstate, shipzipcode, status, tenant_id) values (null, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) [23502-164]. Stacktrace follows:

我很茫然，因为 ZIPCODE 列不再在域类中。任何指导将不胜感激。

编辑：每个请求这里是迁移插件生成的更改：

changeSet(author: "user (generated)", id: "1363806498118-1") {
    dropColumn(tableName: "admission", columnName: "pen")
    addColumn(tableName: "admission") {
        column(name:"pen_id", type:"bigint")
    }       
}


changeSet(author: "user (generated)", id: "1363806498118-2") {
    addColumn(tableName: "customer") {
        column(name: "billzipcode", type: "varchar(50)") {
            constraints(nullable: "false")
        }
    }
}

changeSet(author: "user (generated)", id: "1363806498118-3") {
    addColumn(tableName: "customer") {
        column(name: "shipzipcode", type: "varchar(50)") {
            constraints(nullable: "false")
        }
    }
}

changeSet(author: "user (generated)", id: "1363806498118-4") {
    addColumn(tableName: "customer_costs") {
        column(name: "subtotal", type: "float(19)") {
            constraints(nullable: "false")
        }
    }
}

如果您注意到您的变更集，则 billzipcode 的条目实际上是添加一个新列，而不是重命名 zipcode 列。因此，您仍然必须管理数据迁移。这样的事情应该适用于你的情况：

changeSet(author: 'user (generated)', id: '1363806498118-4') {
    comment { 'Renaming zipcode to billzipcode' }
    renameColumn(tableName: 'customer_costs', oldColumnName: 'zipcode', newColumnName: 'billzipcode', columnDataType: 'varchar(50)')
}
