从字符串转换日期和/或时间时，插入或更新日期字段时出现以下错误转换失败

Question

我正在尝试更新/插入表中的日期时间戳值，我得到‘转换失败时从字符串转换日期和/或时间’：

return UserTableDto.update({
      'firstName': user.firstName,
      'lastName': user.lastName,
      'LastUpdatedBy': user.lastUpdatedBy,
      'LastUpdatedOn': new Date()
    }).then((userDtoResult: UserDto) => {
      resolve(userDtoResult);
    });

用户模型：

import { Table, Column, Model, HasMany, DataType, PrimaryKey, ForeignKey, Default, BelongsToMany, BelongsTo } from 'sequelize-typescript';

@Table({ freezeTableName: true, tableName: 'User', timestamps: false })
export class UserDto extends Model {

    @PrimaryKey
    @Default(DataType.UUIDV4)
    @Column(DataType.UUID)
    userId: string;

    @Column
    firstName: string;

    @Column
    lastName: string;

    @Column
    email: string;

    @Column
    InitCreatedBy: string;

    @Column
    StartDate: Date;

    @Column
    EndDate: Date;

    @Column
    InitCreatedOn: Date;

    @Column
    LastUpdatedBy: string;

    @Column
    LastUpdatedOn: Date;

    @Default(true)
    @Column
    active: boolean;

    @Default(false)
    @Column
    deleted: boolean;

    @Column
    deletedOn: Date;
}

引发以下异常：

我尝试使用new Date().toISOString()，new Date().toUTCString()，new Date().getTime()，但仍然出现相同的错误。

环境：

• 序列化版本: 5.19.0
• Node.js版本: v8.16.0
• 操作系统: Windows 10 64位
• TypeScript版本: 3.3.3333
• sequelize-typescript: 1.0.0
• 单调乏味: 6.3.0

使用sequelize创建了一个问题：Sequelize Issue 11460

Answer 1

我已经通过以下方式解决了我的问题：

return UserTableDto.update({
      'firstName': user.firstName,
      'lastName': user.lastName,
      'LastUpdatedBy': user.lastUpdatedBy,
      'LastUpdatedOn': Sequelize.fn('GETDATE')
    }).then((userDtoResult: UserDto) => {
      resolve(userDtoResult);
    });

它将输出以下查询：

UPDATE [UAM_User] SET [LastUpdatedOn]=GETDATE() OUTPUT INSERTED.* WHERE [userId] = @0

这将适用于SQL server。如果使用Oracle或某些数据库，请使用生成日期的函数。例如，在MySQL中，获取当前时间的函数是NOW()，因此该函数为：

'LastUpdatedOn': Sequelize.fn('GETDATE')

或者需要将object类型从Date改为string，并以yyyy-MM-dd HH:mm:ss.SSSSSS格式传递格式化的日期值：

@Column
LastUpdatedOn: string; // Changed from Date

然后将值传递到此列需要传递格式化的日期值：

    const d = new Date();
    const dt = `${d.getFullYear()}-${d.getUTCMonth() + 1}-${d.getDate()} ${d.getHours()}:${d.getMinutes()}:${d.getSeconds()}.${d.getMilliseconds()}`;

    return UserTableDto.update({
      'firstName': user.firstName,
      'lastName': user.lastName,
      'LastUpdatedBy': user.lastUpdatedBy,
      'LastUpdatedOn': dt
    }).then((userDtoResult: UserDto) => {
      resolve(userDtoResult);
    });
