插入或更新日期字段会出现以下错误从字符串转换日期和/或时间时转换失败

Question

我正在尝试在表中更新/插入日期时间戳值，我收到“从字符串转换日期和/或时间时转换失败”：

    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<UserDto> {

    @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;
}

抛出以下异常：

我尝试使用 new Date().toISOString(), new Date().toUTCString(), new Date().getTime() 但仍然是同样的错误。

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

Answer 1

我已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);
    });

这将输出以下查询：

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

这适用于 SQL 服务器。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()，所以函数是：

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

或者需要将对象类型从日期更改为字符串，并以“yyyy-MM-dd HH:mm:ss.SSSSSS”格式传递一个格式化的日期值：

@Column
LastUpdatedOn: string; // Changed from Date

那么向该列传值需要传入格式化的日期值：

    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);
    });
